Machinery Secret Technique at Full Mastery, a New Use

After Xu Bai finished speaking, everyone present was stunned.

Song De, in particular, always felt that Xu Bai's smile looked creepy.

I can't quite explain why I feel this way, but it's just that chill down my spine, like I'm being watched by something terrifying.

In short, it's absolutely terrifying.

The Prefect Zhou was different. Having been in officialdom for many years, he immediately understood Xu Bai's intention and said with a helpless bitter smile, "Lord Xu, please don't do anything outrageous. These families are top-notch in Purple Wood Prefecture. You can't do anything too crazy."

He felt it was necessary to talk to Xu Bai about it.

After all, the rumors circulating in the martial arts world say that Xu Bai is not only ruthless, but also vindictive and extremely petty.

Although things passed down in the martial arts world often become distorted over time, at least one or two percent of them can still be believed.

"Don't worry, Lord Zhou. Although I am not a good person, I will never make things difficult for you," Xu Bai said cheerfully.

Just kidding, he understands the proper etiquette and social graces, so he naturally knows how to handle things in a more nuanced way.

Prefect Zhou heard Xu Bai say this, he breathed a sigh of relief.

It would be best not to do anything foolish. He was afraid that Xu Bai might get angry and cause bloodshed in the prison, which would be difficult for him to handle.

At that point, if you were to punish him, it would be difficult to explain to Yun Zihai, and even more difficult to explain to His Majesty.

If he is not punished, his prestige in the Purple Wood Prefecture will likely be completely destroyed.

"Then I'll take my leave. Lord Xu, please wait here for me," Prefect Zhou.

Now that he had received Xu Bai's assurance, Prefect Zhou was naturally at ease.

He and Yun Zihai also corresponded regularly, Yun Zihai once mentioned something about Xu Bai.

The gist is that although Xu Bai Xu Bai has some flaws, he is an excellent friend because he never goes back on his word.

Prefect Zhou believed Yun Zihai, and therefore also believed Xu Bai's words.

After Prefect Zhou left, only Xu Bai and Song De remained in the prison cell.

"Lord Song, I originally wanted you to investigate Ji Xiaojian's death, but it seems you'll have to stay quietly in the prison cell for now," Xu Bai said with a smile.

If we follow his method, the other party will inevitably take action when they see these family members imprisoned.

The most obvious thing is that the movement is directed in his direction.

If Song De stays, he'll have another helper.

Xu Bai was always adept at getting people onto the boat.

"Don't worry, Lord Xu," Song De said. "I will hide in a nearby place so that we can open this breach."

Xu Bai nodded; now it was just a matter of waiting for what was to come.

Purple Wood Prefecture.

On an extremely bustling street.

This place is different from other streets; both the surrounding houses and the vendors on both sides sell extremely exquisite items.

The reason is simple: this street is inhabited by wealthy and powerful families.

In this world, in many places, families are at odds with each other, but in many other places, families stick together for mutual support.

Most families in Purple Wood Prefecture adopted a group-based approach to mutual support.

But today, this way of sticking together for warmth has actually brought convenience.

"Walk!"

"Hurry up!"

"Where is your master? Tell him to put on these chains and come with me to the Prefectural Office."

Dozens of constables went from house to house, bringing out the heads of each family.

When these family heads left, they were all completely bewildered, having no idea what had happened.

"Oh, Patriarch Zhao Family, you're here too?"

"Patriarch Ouyang Family, how did you get arrested too?"

"No, why are you all like me?"

Along the way, many family heads exchanged glances. To become a family head, one must naturally possess exceptional abilities.

Soon, they all shuddered, realizing what had happened.

"It must be because of Xu Bai!"

This is their idea.

All twenty-odd of them caused trouble during the day, and by nightfall, they were all caught, not a single one was left. After a little speculation, the conclusion was reached.

"Hurry up."

The yamen runners began to urge them on.

The crowd surged forward toward the Prefectural Office.

Upon arriving at the Prefectural Office, they saw Prefect Zhou waiting there.

One of the family heads, surnamed Zhao, couldn't hold back any longer and shouted, "Lord Zhou, we haven't done anything wrong, why are you arresting us?"

The others echoed this sentiment, saying they had never done anything wrong and questioned why they were all being arrested.

Prefect Zhou expressionless, not even bothering to say anything, and waved his hand, saying, "Throw them all into the jail! If anyone dares to resist, you don't need to lift a finger; just let him run. I'll just accuse him of fleeing from justice."

These family heads, ranging from the lowest to the fifth rank, might be difficult for the yamen runners to stop if they really started causing trouble.

But after hearing Prefect Zhou's words, the heads of the families all fell silent.

Seriously though, they might be able to escape, but what happens after that? Are they supposed to be wanted by the Great Chu Kingdom and live as fugitives? They all have families and children, and some even have considerable wealth; how could they do such a thing?

Upon thinking of these things, the heads of the families all fell silent.

Soon, the constables drove the group away, took them to a special cell, locked it, and left.

The heads of the families exchanged glances and looked around at their surroundings.

Unlike other dark and damp cells, this cell was well-lit.

The furniture, in particular, is very complete in all shapes and sizes.

Even the bed was covered with a soft mattress.

It's exquisite and well-made.

Especially noteworthy is that there was someone lying on the chair next to the bed.

People? The family heads rubbed their eyes, wondering if they were seeing things.

Why is there someone else here? A young man was sitting in a chair, and his posture was extremely arrogant.

In the young man's right hand, he held a knife.

The blade was sharp, gleaming coldly in the light.

"Xu Bai!" The head of the Zhao Family family, who had recognized the young man at the beginning, exclaimed in surprise.

When he shouted that, everyone around him reacted.

Having all reached the position of family head, they naturally had information. Those who reacted quickly had already gathered together, all cautiously watching Xu Bai.

Legend has it that Xu Bai is a vengeful and powerful man, so they naturally have to be on guard against him.

"Don't be afraid, everyone. I'm not a man-eating beast. Don't make that face," Xu Bai said casually, waving his hand.

His appearance only made the heads of the family more suspicious.

Among this group, the head of the Zhao Family family was obviously the leader. After hearing what Xu Bai said, he quickly said, "Xu Bai, I advise you not to be impulsive. The worst of us is a seventh-grade expert. There are more than twenty of us. You may not be able to defeat us."

For some reason, he felt that what he was saying lacked any confidence.

Despite having more people on their side, they felt completely insecure, while the opponent, who was only one person, terrified them.

"We're all civilized people. Fighting and killing like this is too uncivilized." Xu Bai smiled gently, but his words made people feel like they were in an ice cellar. "Besides, if I really wanted to kill you, you lot wouldn't be enough to fill my teeth."

As soon as the words were spoken, the family heads all took a step back.

It's not that they lack courage; on the contrary, they are quite courageous.

Each of them fought their way to the position of family head through fierce battles; without courage, they could never have achieved such a status.

But sometimes, when you're penniless, you're more decisive.

Having achieved their current wealth and status, they have become timid and hesitant, after all, with so much wealth and glory to enjoy, how could they possibly give it up here?

"You mean... not to make a move?" The Zhao Family patriarch understood the implication and asked.

"Of course, as long as you tell me who instigated you and put me in this situation, then everything is negotiable," Xu Bai said calmly. "If you don't tell me... I won't take action against you, but do you all know how you got in here?"

"What is it?" The Zhao Family patriarch looked around, and seeing that no one answered, he had to speak again.

"I'm merely suspected, without any evidence. Your combined pressure is bordering on false accusation," Xu Bai said. "Of course, it's not a big deal, but as you all know, His Majesty the Emperor values me highly. If I'm innocent, I only need to say a few words to His Majesty..."

He didn't continue speaking, but the meaning was already quite clear.

In Xu Bai's view, there was no need to resort to force at this time. A little intimidation would be enough to make these family heads, who were used to being pampered, confess one after another.

"As long as you answer my questions, the so-called charges will naturally disappear," Xu Bai continued.

"What's the problem?" the Zhao Family patriarch asked.

In fact, he had already heard it very clearly.

Everyone present, including him, understood the meaning behind his words.

If that's the case, they're essentially slapping the emperor in the face.

In the Great Chu Kingdom, what are the consequences of slapping the emperor's face? Even being torn to pieces wouldn't be enough.

The thought of all this sent chills down the spines of the family heads, some even pounding their chests in regret.

I was too excited and impulsive at the time. If only I had played it safe, otherwise I wouldn't be in this situation. "Tell me, who exactly instigated you to put pressure on us?" Xu Bai played with the Ghost-Head Saber, his eyes narrowed slightly.

"It's a letter. We all received a letter." The Zhao Family patriarch took out the letter from his pocket and said, "The letter says that you are a murderer. If we don't get rid of you, none of our families will survive. And you just happen to be in prison, so... we are worried that we might be implicated, so we joined forces to put pressure on you as the letter says."

"You carry the letter with you at all times?" Xu Bai asked, frowning.

He felt that perhaps they had been living in peace for too long, and these family heads had lost not only their former vigor but also their courage.

"I'm just in case things change, so I can pin the blame on this letter." The Zhao Family head handed the letter to Xu Bai and said, "Lord Xu, that's all."

At this point, he also changed how he was addressed.

Xu Bai took the letter, pulled out a paper crane from his pocket, ignored the group of people, and instead used the Seeking Traces on the letter.

The paper cranes fluttered up and down before settling on the letter.

A moment later, it turned into a pile of ashes and disappeared.

"They're really cautious; they've even cut off their escape route," Xu Bai thought to himself, stroking his chin.

This approach completely cuts off any Seeking Traces. Clearly, the other party also knows that if they leave any clues, Xu Bai could easily follow the trail.

But here's the problem: the trail seems to have gone cold again.

The other party left no loose ends when they did things.

Xu Bai was frowning in thought, while none of the family heads dared to answer, all standing trembling to the side.

After all, this person's status is different now, so it's best for them to speak as little as possible to avoid causing any trouble.

"Someone come here!" Xu Bai walked to the door and called out to the outside.

A yamen runner came in from outside, clasped his hands in greeting, and said, "Greetings, Lord Xu Lord Xu?"

The Prefect Zhou had already instructed them to do their best to meet any requests Xu Bai made, so the yamen runners were very respectful.

"Take these people to other cells, the farther away from here the better," Xu Bai said.

Since the matter was over, Xu Bai didn't want to say anything more.

"Yes!" the constable replied.

The family heads came in looking completely bewildered, and were then taken away, also looking completely bewildered, to a cell far away from Xu Bai.

After everyone had left, Xu Bai looked at an empty spot and asked, "Lord Song?"

Song De's footsteps sounded as he walked to Xu Bai's cell and said, "Lord Xu, it seems the other party is truly meticulous."

"Not entirely," Xu Bai said. "Lord Song, you don't need to stay here with me. Go and investigate the other families. Those that haven't joined forces to exert pressure may have problems."

Since the pressure is being exerted through joint efforts, the more families involved, the better. But with only twenty-odd families involved, something fishy is clearly going on.

If the other party wants to clear themselves of any wrongdoing, this is undoubtedly the best approach.

When the incident comes to light, the other families who were not involved will naturally minimize their suspicions.

Song De said, "Actually, I was also planning to investigate, but Lord Xu, do you think it's better to investigate openly or secretly?"

As the head of the Bureau of Surveillance, Song De was quite capable, having handled many cases and naturally understanding this principle.

His dilemma lies in the interplay of light and darkness.

Whether to investigate openly or covertly, there's a nuance to it.

An open investigation might alert the enemy, but it's easier to launch a surprise attack and achieve unexpected results.

Investigating covertly avoids alerting the enemy, but it often restricts one's actions, as it's conducted in secret and therefore requires secrecy, preventing the implementation of many maneuvers.

"Of course, we'll investigate and monitor them covertly," Xu Bai said. "We don't need to investigate too thoroughly, just keep an eye on them. If the other side wants to move these pieces, they will definitely make a move. I just don't know if Lord Song has enough manpower?"

Song De was the only one on this trip, but dozens of families did not participate.

"I will go to Lord Zhou to borrow people." Song De's meaning was clear. "Now that things have come to this point, I actually understand that this matter has absolutely nothing to do with Lord Xu, but we must find out the true identity of the person behind it, otherwise it will be a slap in the face to my Bureau of Surveillance."

All the signs are now clear; all that's missing is the crucial piece of evidence, otherwise Xu Bai could leave at will.

"Whether I go out or not is not important," Xu Bai said with a smile. "As long as I am here, the other side will take action, and that is the most important thing."

"Alright, then Lord Xu, please be careful. I'll go investigate thoroughly right away." Song De didn't waste any time and turned to leave.

After Song De left, Xu Bai leaned back in his recliner and quietly worked on the progress bar.

He wasn't in a hurry at all, because no matter what the scheme was, it would be futile if it couldn't overwhelm him in terms of strength.

The progress bar is slowly increasing; this book, "The Machinery Secret Technique," is almost finished.

A lakeside far from the prison cells.

The man in the straw hat sat on the ground, not fishing, but just staring at the lake, motionless, as if in a daze.

The surroundings were extremely quiet, and the lake was as calm as still water, but the man in the straw hat was not at peace.

Ji Xiaojian is dead. He erased all clues, but as a result, the matter made no progress. On the contrary, he suffered one loss after another.

"Does this Xu Bai really possess extraordinary abilities?" the man in the straw hat thought to himself as he looked at the calm lake.

Just then, the man in black arrived on time, his steps hurried.

"Report!"

Accompanied by hurried footsteps, the man in black shouted.

"Speak!" The man in the straw hat snapped out of his thoughts and glanced indifferently at the man in black.

The man in black stopped abruptly, panting heavily, and said, "Sir, it's over."

"Nonsense!" the man in the straw hat roared. "What do you mean 'that's it'? Speak properly!"

The man in black was startled and quickly calmed himself down, saying, "Those who joined forces to exert pressure have all been arrested and imprisoned, accused of... false accusation."

"Boom!"

A terrifying pressure emanated from the man in the straw hat.

The lake surface was suddenly blasted up with water splashes three meters high, shattering the tranquility.

"Excellent! Excellent!" The man in the straw hat trembled with anger. "What a brilliant move to turn defense into offense! By arresting all those who were putting pressure on us, there are no more people putting pressure on us. Truly ingenious!"

The man in black dared not utter a single word, fearing that he might offend the man in the straw hat.

The man in the straw hat fell silent, simply standing by the lake, watching the surging waves.

Silence fell again.

After a long while, the voice of the man in the straw hat could be heard.

"Since he's gone this far..." the man in the straw hat said coldly, "Send over the Twelve Sword Formation, and I'll take his life!"

Although he appeared calm on the surface, the man in the straw hat could not hide the anger in his heart.

"The Twelve Sword Formation?" The man in black shuddered. "But sir, they are our last trump card. If we fail..."

"Can't succeed?" The man in the straw hat grabbed the man in black by the collar and said, "Who am I? I will not fail!"

The man in black instinctively replied, "But..."

This was just something he said subconsciously, because the man in black didn't know what to say next.

"If we fail, we'll take everyone and flee the Purple Wood Prefecture," said the man in the straw hat. "We'll avenge this another day."

The man in black had his face covered by a black cloth; if it weren't for the black cloth, his expression would have been quite interesting.

In the beginning, who said they would only kill Xu Bai?

Now, who is it that's talking about running away?

Do people change so quickly these days?

Of course, the man in the straw hat didn't notice the man in black and continued talking to himself.

"Hehe, besides the Purple Wood Prefecture, he has several other places. When he joins forces with others, it will be a natural outcome."

At this point, the man in the straw hat didn't want to try any other methods.

Plans can be adapted.

In other words, plans can be changed when they don't work.

He also realized where he and Xu Bai differed.

Actually, if he had planned carefully, he might not have lost, but the problem was that the whole thing involved killing Xu Bai.

Xu Bai is ridiculously strong, how can we kill him?

When someone possesses the strength to overcome skill with brute force, you cannot solve the problem even if you use all your tricks.

This is like certain special moments where, as long as you are strong and tough enough, you don't need to change your posture to ease the tension. You can just stick to one posture and no one can withstand it.

Therefore, the man in the straw hat felt that he had no chance.

If there's no chance left, why stay here and throw your life away?

Nobody likes to die. Xu Bai's journey to the Upper Capital is still long, and this isn't his last chance, so he's not worried at all.

Along the way, Xu Bai wasn't the only one who tried to kill him. The enemy of my enemy is my friend. When we unite, it'll be perfect.

That so-called Twelve Sword Formation was his last attempt, and the strongest method he could muster, since the old guys didn't dare to come out, so this was all he could do.

If that doesn't work, I'll have to run away.

"Go and do it quickly!" the man in the straw hat said. "Remember, don't let a word of it leak out. I'll take you with me when the time comes."

"Thank you, sir!" The man in black quickly agreed and left without lingering.

After the man in black left, the man in the straw hat looked at the lake in front of him and sighed.

"Xu Bai, I will kill you!"

The same words were spoken, but this time they came out without much confidence.

Time slips away.

Several days have passed in the blink of an eye.

Over the past few days, Song De has been monitoring the movements of the remaining families.

But here's the problem: those families seem to have vanished, going about their daily lives without making a sound.

That's easy to say, since the other party must have concerns, worried that acting rashly might arouse suspicion.

Song De didn't care about this, since his job was just to keep watch.

But Xu Bai saw something different.

Does the fact that the other party remains silent mean they are exhausted and unable to continue?

If that's the case, then it's an excellent opportunity.

As for whether it's true or false, just try it and everything will be clear.

Song De's voice rang out in the brightly lit cell.

"Lord Xu, I heard you were looking for me?"

During this period, Song De had been closely monitoring those families.

This was the first time Xu Bai had met him recently.

Looking at Xu Bai, who was lying leisurely in the chair, Song De's lips twitched.

This isn't jail time; this is clearly a vacation.

All that's missing is two girls from the Spring Rain Pavilion to dance here.

If that were the case, Song De would rather he were the one imprisoned.

That would feel so good...

Looking at Xu Bai's leisurely demeanor, and thinking about his own busy schedule over the past few days, Song De felt a tightness in his chest.

"Oh? Lord Song has arrived already?" Xu Bai stood up from his chair, put the "Machinery Secret Technique" aside, and said with a smile, "Of course, I have a favor to ask of Lord Song."

"What Lord Xu is doing is naturally my business, Song's business." Song De patted his chest loudly and said, "Lord Xu, please speak freely."

Xu Bai walked a short distance in front of Song De and said, "Actually, it's not particularly important. I just want Lord Song to go out and spread a message that if he apologizes to me for the wrongs he committed before, I will forgive him."

Upon hearing this, Song De was slightly taken aback, not understanding what Xu Bai meant.

This is hardly a good strategy, is it? The other party is most likely the kind of person who is extremely loyal. Even if this request gets out, it might not be effective. It's better to continue monitoring them.

Of course, he couldn't express it, so he could only lower his head and think hard, trying to persuade Xu Bai with other reasons without hurting Xu Bai's feelings.

Xu Bai, of course, saw through it and laughed, "Lord Song, how could I not know such a simple question? I don't necessarily want the other side to surrender; I just want to create discord between them."

Upon hearing this, Song De, who was deep in thought, immediately brightened up.

He seemed to have discovered the brilliance of the plan.

The other party had previously used pressure tactics.

Xu Bai's current strategy is remarkably similar.

"Lord Xu, I understand now," Song De said.

"It's good that Lord Song has understood. If this matter succeeds, the other side will definitely take action. We will then adapt to the situation and see if we should close the net," Xu Bai said.

As our ancestors said, conquering cities is inferior to conquering hearts and minds.

Even if they themselves are as steadfast as a rock, they don't know what the others in their own camp are thinking, and naturally, this rift will emerge.

Once a rift develops between you, things will be much easier later on. You can then close the net and get back to what you were doing.

Song De left quickly, as he was excited because he was about to see clues.

Xu Bai remained as steady as Mount Tai, continuing to work on "The Machinery Secret Technique," the progress bar of which was becoming increasingly complete.

The next day.

The sun today was as warm and peaceful as ever.

However, in some places, dissenting voices have emerged.

The man in the straw hat, listening to his subordinate's report, suddenly turned his head and asked, "What do you think of this matter?"

The man in black stood to the side, forcing a wry smile. "My lord, I am absolutely loyal, but I can't guarantee what will happen to the others, after all..."

He didn't say what came next, but the meaning was already quite clear.

"The Twelve Sword Formation must be completed, but I don't know if these twelve people will be loyal." The man in the straw hat paced back and forth, thinking to himself.

After a long while, he raised his head again and said, "You keep a close watch on the Twelve Sword Formation. If anything goes wrong, come find me immediately. By the way, have you chosen the right time?"

The man in black nodded quickly and said, "Every five days, at noon, Prefect Zhou will go out to inspect the situation in various places. This is his habit. At that time, only Xu Bai will be in the prison cell."

The Prefect Zhou is a scholar and a skilled fighter. We must avoid these people, otherwise killing Xu Bai will become even more difficult.

"Alright, go now and tell them that the day after tomorrow at noon is the day to make your move," the man in the straw hat said slowly.

"Yes!" the man in black replied, preparing to turn and leave.

But just then, he suddenly felt a pain in his chest, and a section of the fishing rod pierced through his body.

"My lord, I have been so loyal to you, yet you still believe I would betray you?" the man in black asked with difficulty, enduring the pain in his chest.

"Even if Xu Bai dares to disregard past grievances, I cannot guarantee whether it is absolutely safe. Only the dead are truly safe." The man in the straw hat said slowly, "Besides, you will be going to find the Twelve Sword Formation. Don't worry, I will personally monitor the Twelve Sword Formation. If there is any abnormality, we will simply run away."

The man in black gave a bitter smile, "It seems that in the eyes of adults, no one is trustworthy anymore."

The man in the straw hat remained silent, not uttering a single word, but his meaning was already quite clear.

"You will lose, you will lose badly, because you are no match for Xu Bai." The man in black used all his strength to mock, "At least Xu Bai knows that you should not use those you doubt and you should not doubt those you use, but you are full of suspicion. I will be waiting for you down there. I believe you will come soon."

"Hehe, that's my business." The man in the straw hat exerted a little force, and a powerful force seeped out from the fishing rod.

The man in black was torn to pieces, turning into a cloud of blood mist.

After doing all this, the man in the straw hat went to the lakeside, placed his fishing rod in the water, and gently shook it to clean off the bloodstains before leaving the lakeside.

Not long after the man in the straw hat left, the air around him rippled, and another man in black appeared, covered in sweat.

"The lord... indeed suspected us."

"No, I have to run, or I'll die."

"No, I can't run away. That's it! Xu Bai said he'd forgive and forget, I need to go to him."

Thinking this, the man in black twisted his body again, merged into the air, and disappeared.

Xu Bai was unaware of what was happening in the outside world.

During this period, he truly embodied the meaning of "staying at home".

Every morning, noon, and evening, professional staff deliver meals; otherwise, it's just about grinding progress.

Xu Bai's assessment of this was simply—awesome.

Being waited on hand and foot, and even having your strength enhanced—it's impossible not to feel happy about it.

If things could continue like this, and with the addition of two top courtesans from the Spring Rain Pavilion, it would be wonderful.

Song De's side was also very helpful; after the message was sent out, they continued to monitor those families.

As for the rest, the other party hasn't made any moves.

Xu Bai said this was normal.

It takes time for an arrow to fly from the bowstring and hit the target.

Such big news needs time to process, right?

Staying calm and composed is the most important thing.

Before me, the progress bar of "The Machinery Secret Technique" finally reached its last bit, achieving perfection.

Looking at the pale blue smoke in front of him, Xu Bai smiled contentedly.

Another book is complete! The pale blue smoke transformed into words, gradually condensing and becoming clearer and clearer in the blink of an eye.

You have grasped the Machinery Secret Technique and Machinery Secret Technique.

This time, there's no fusion option; instead, it's a completely new skill.

A flood of information rushed into my mind, and at the same time, a new attribute panel appeared before my eyes.

[Name: Xu Bai]

[Realm Level: Fourth Rank Loose Cultivator.]

[Severing Break Three Styles (Tier 4): Max Level]

[Inverted Purple Firmament Gale Wind Yin Yang Break (Tier 6): Max Level.]

[Returning Wind Flowing Snow (Tier 5): Max Level.]

[Movement-Armor Break Second Revolution (Tier 4): Max Level.]

[Cosmic Shift (Tier 4): Max Level]

[Vajra Heart Demon Body (Tier 4); Max Level.]

[Strengthening Kidney Gathering Art (Tier 5): Max Level.]

[Hundred Poisons True Explanation (Tier 3): Max Level.]

[Paper Art Essence (Tier 5): Max Level]

[Undying Body (Fragment) (Tier 5): Max Level.]

[Machinery Secret Technique (Tier 5): Max Level.]

[Comprehension: Max level.]

As expected, it's another Tier 5 skill. No wonder it took so long to grind for.

Even just a fifth-tier skill is worth it, let alone a skill that he is extremely interested in.

Xu Bai slowly closed his eyes, carefully sensing the information in his mind.

After he had absorbed all the information, he suddenly opened his eyes.

His gaze fell on the Ghost-Head Saber in his hand, and he muttered to himself, "So, Machinery Secret Technique can be used like this?"
