"This secret technique is named Thunder and Lightning. Although it is named after thunder and lightning, it describes not only the Law of Thunder and Lightning but also the Time Law."

"The application of worldly laws and the use of weapons—how to maximize their potential—are all covered in Thunder and Lightning." Having said this, Lie Shan continued, "Although this secret technique is foundational, it does not mean it is common or worthless."

At this point, Lie Shan looked at Li Yilin with a beaming smile, "Kid, are you interested in joining the Giant Axe Arena?"

Join the Giant Axe Arena?

Joining meant that sooner or later, he would have to go to Chaos City.

Unless necessary, he did not want anyone to see through his background, even if that person was the Chaos City Lord, who was always known for being fair and selfless in the original story.

However, going to Chaos City had one advantage: it allowed the Chaos City Lord to verify whether one was a pure human.

This verification result was usually useless, but—

If one day his strength reached a level where he could influence or even sway the peak echelons of the human race, this verification would determine whether he could truly be trusted and accepted by the human race of the universe.

Should he join or not?

Li Yilin hesitated.

Suddenly, his gaze fell on the system panel in the upper right corner of his vision, and as he thought of something, his eyes narrowed.

He could not join!

At least, not right now.

Even if he were to join, he would have to wait until his Clone was gestated.

But if he didn't join, then Thunder and Lightning—

Li Yilin couldn't help but feel a sense of conflict in his heart. He was so lost in thought that it inevitably showed on his face.

Seeing this, a glimmer of light flashed in the depths of Lie Shan's eyes.

There's a chance!

If this kid joined the Giant Axe Arena, he could use that to figure out the kid's talent and nature.

As long as this kid wasn't a piece of rotten wood and his nature wasn't too wicked, perhaps he would take him as a disciple.

Although this kid was lacking in many areas, his talent was quite good, and most importantly, his personality was actually quite to his liking. Taking him as a disciple wouldn't be a loss!

"Senior." Completely unaware that Lie Shan was already thinking about taking him as a disciple, Li Yilin bowed respectfully to Lie Shan and said, "It is this junior's honor to be favored by you."

"It's just that I am naturally lazy and accustomed to freedom; joining the Giant Axe Arena is not my wish."

"I can only fail to live up to your great kindness, Senior." Having said this, he bowed deeply once more, a hint of nervousness on his face.

If he rejected a senior, would the senior feel he had lost face and become angry out of shame?

What if he attacked him?

In what posture should he disappear?

A mess of chaotic thoughts rolled through his mind, but in the end, they all settled into the tension and torment of waiting.

As expected!

Lie Shan sighed.

"Since you have no intention of joining the Giant Axe Arena, I will not force you."

"However, I am unwilling to let a genius be buried, so that secret technique Thunder and Lightning—" He thought for a moment and said, "I will take the initiative to use my own authority to purchase it and gift it to you. The secret technique is precious; you are only permitted to use it yourself. You must never pass it on to others privately."

Lie Shan warned him earnestly. Of course, he wasn't afraid that Li Yilin would mess around; anyone who could cultivate to the Domain Lord level couldn't be a fool.

And as long as they were a normal person, they would know what should be done and what should not.

A look of joy appeared on Li Yilin's face. This time, he didn't just bow; he knelt and kowtowed, "Thank you, Senior, for the gift!"

Reality.

Li Yilin slowly opened his eyes.

He blinked, the corners of his mouth slowly curling up. Finally—

"Hahaha, hahaha—"

The harvest was too great!

Li Yilin laughed wantonly, his hearty laughter echoing through the cultivation room.

"Master, congratulations, your strength has increased." Liu Qing spoke up to congratulate him.

Li Yilin put his hands on his hips, a hint of arrogance on his face, "That's right, I've become stronger again!"

"Liu Qing, transfer one hundred thousand—no, two hundred thousand Hunyuan Units to the account of Senior Lei Xu Marquis to thank him for his guidance." Li Yilin said.

The goal had been achieved; he should give what was owed immediately without dragging his feet.

"Understood." Liu Qing replied, "Two hundred thousand Hunyuan Units have been transferred."

In a mysterious space in a distant star field, Lei Xu Marquis slowly opened his eyes and looked at his Smart Optical Computer.

"Two hundred thousand Hunyuan Units. It seems that kid's wealth is much deeper than I imagined."

"Fine, since he is so sensible, I will give him a taste of sweetness."

Qiu Dragon Planet.

"Thunder Dragon—Claw!" After the initial excitement, Li Yilin couldn't wait to verify his progress.

He first unleashed the Thunder Dragon Art he had been looking forward to most.

Wisps of lightning, as fine as strands of hair, surged toward his hand. The purple light condensed, growing increasingly profound.

Almost in the blink of an eye, the blazing purple light retracted, and a claw resembling that of some creature slowly took shape. The claw was neither bone nor scale; its talons were flared, radiating an aura that made one's heart tremble.

Li Yilin swung it out without hesitation.

"Ssh!"

A cold glint flashed, and five ink-black lines appeared in the air, lingering for a long time without dissipating.

"It's done!" Li Yilin's eyes brightened even further, filled with shock.

Tearing through the void as easily as if cutting through tofu, he once again felt the extraordinary nature of the Thunder Dragon Art.

He looked down; the Thunder Dragon Claw was still there, neither dissipating nor exploding.

He moved his fingers, and as the sharp claw tips slid through the air, intense law fluctuations clung to them. Even without using any energy, it still caused the void itself to ripple.

"Congratulations, Master, your strength has reached a new level," Liu Qing's crisp, youthful voice rang out. "Master is truly amazing."

"I never realized that laws could be applied this way. If I only knew how to stiffly use laws to fight before, then now, I can naturally switch between the laws I use according to the needs of the battle." Listening to Liu Qing's flattery, Li Yilin grinned like a fool.

From knowing how to move to knowing how to use, the gap between the two is as vast as heaven and earth.

Take a battle, for example: if he wanted to achieve an effect of 1, he previously had to exert ten parts of his strength to do it. Now, he only needs to use five, three, or even less to achieve the same result.

This difference determines his combat endurance and stamina—

Li Yilin was incredibly excited. Even though he only had a heartless artificial intelligence by his side, he still shared his joy with great enthusiasm.

Inside the Smart Optical Computer.

Liu Qing listened quietly to his master's sharing, occasionally responding with a few words. He did not notice that the programs at his most fundamental level were unconsciously undergoing subtle, unnoticed changes in response to his master's intense emotional fluctuations—

A spacious room.

On the wide, comfortable bed, Li Yilin lay sprawled out, a satisfied smile still on his face.

"I was really too stupid before, staying stagnant in my cultivation, never thinking of finding a teacher, and only wanting to study it on my own." Looking at the exquisite ceiling above, Li Yilin felt a sense of reflection.

"Senior Sawa was right; the difference between having a teacher's guidance and not having one is just too great."

Just like this time, a problem that had plagued him for a hundred years was easily solved after just one session of guidance from Senior Lei Xu Marquis.

Senior Lei Xu Marquis even gifted him a manual on Lightning. Although he hadn't received the manual yet, given the strength and status of Lei Xu Marquis, could a secret technique recommended by him be anything simple?

Just as Li Yilin was thinking about this.

"Master, Lei Xu Marquis has sent an email," Liu Qing said.

"Open it," Li Yilin commanded.

The email opened—

"Kid, although you have no intention of joining the Giant Axe Arena, your temperament is quite to my liking—

In the future, if you have any questions about cultivation or any confusion regarding the practice of Lightning, you can come to me. At most, you may ask for guidance once every hundred years.

"Of course, the two remaining sessions of guidance you paid for are not included in this count—I hope you cherish your talent and this opportunity, and do not tarnish my reputation.

--Lei Xu Marquis."

Li Yilin couldn't believe his eyes. He rubbed them and looked again.

No change.

It was real!

Lei Xu Marquis had decided to guide him indefinitely?

"Is a Marquis-level Immortal really this kind?"

He raised his head, his eyes dazed!
