Experimental Subject!

Upon hearing that the second method could make them stronger, both Dugu Bo and Dugu Yan felt their breath hitch.

Ying Chengfeng spoke again, "If you are willing to cooperate, I can tell you how to do it."

Dugu Bo looked at Dugu Yan with a complex expression.

If he could, he would have used force to make the other party submit.

That way, he and his granddaughter would not have to suffer this humiliation.

Ying Chengfeng could see that this grandfather and granddaughter were simply prideful.

He said bluntly, "Don't feel pressured; my research is very friendly."

"Hmph." Dugu Bo snorted, not wanting to say more.

But his demeanor clearly indicated that he had practically agreed.

He was in a state of half-reluctance and half-compliance.

Ying Chengfeng could not be bothered to haggle over these trivialities with them.

He said, "The activity of the toxins within your bodies can actually be used to condense a Soul Core."

Dugu Bo asked in confusion, "What do you mean?"

Ying Chengfeng explained, "Your poison can be understood as a fire that never goes out."

"And what you need to do is wrap it up."

"There is a saying that paper cannot wrap fire, but that is only because the paper is not thick enough or of good enough quality."

"Once you wrap this fire, you can completely control it."

Upon hearing this, Dugu Bo had another question, "If the paper wraps the fire, how can you still use this fire to burn people?"

Ying Chengfeng still wore an expression as if looking at a fool, saying, "Before using the fire, can't you remove the excess paper? Let this fire ignite the paper?"

"Wouldn't such a fire be bigger and stronger? Once the battle is over, wrap it back up."

Hearing this, Dugu Bo fell into a long silence.

After a good while, he asked, "How exactly do I do it?"

Ying Chengfeng did not answer his question immediately.

Instead, he beckoned to Yu Feiyan behind him, "Come here for a moment."

Yu Feiyan walked to Ying Chengfeng's side, remaining silent, simply waiting for his instructions.

Only then did Ying Chengfeng answer Dugu Bo, "Gather the active toxins in your body to your dantian and wrap them with your soul power."

After listening, Dugu Bo looked strange, "It's that simple?"

"Simple? Why don't you try it." Ying Chengfeng smiled lightly.

It sounded simple enough, but the difficulty lay in whether one could actually contain it.

Dugu Bo hesitated for a moment; he did not choose to let his granddaughter risk trying it, intending to test it himself first.

Regardless, he was a Title Douluo; even if something went wrong, he could suppress it.

But his granddaughter would definitely not be able to contain it.

With that thought, Dugu Bo sat cross-legged and began to attempt the method Ying Chengfeng had described.

All the soul power in his body converged at his dantian.

At this moment, Dugu Bo finally discovered his own problem.

His soul power had clearly gathered at his dantian, but some toxins still remained in his meridians.

"Are these the active toxins I couldn't control?"

Dugu Bo was completely shocked.

His soul power had always circulated throughout his body before.

He had assumed these toxins were part of his own soul power.

But now, he realized he was wrong!

However, at this moment, he discovered that those toxins were becoming restless.

Like a starving child, they were desperately lunging toward where the 'milk' was.

These active toxins were also heading toward the dantian.

Their food was soul power!

Ying Chengfeng said to Yu Feiyan beside him, "Feel his state carefully."

Yu Feiyan pursed her lips, then said weakly, "I can only look with my eyes; I cannot probe with soul power."

"Then look with your eyes." Ying Chengfeng said, then told Dugu Bo, "Take off your shirt and let us have a good look."

Upon hearing this, Dugu Bo, who was in the middle of trying to wrap the active toxins with his soul power, felt his mouth twitch.

"Kid, don't go too far!"

Ying Chengfeng frowned and said, "Otherwise, should I let your granddaughter strip instead?"

"I said I would teach you what to do, and you would cooperate with my research."

"Are you planning to go back on your word now?"

Hearing this, Dugu Bo calmed down a little.

Compared to his granddaughter being seen, it didn't matter if he, a grown man, was the one exposed.

"Staring at a man's body at such a young age, be careful you don't get a stye." Dugu Bo retorted stubbornly, taking off his upper garment.

At this moment, a green light appeared on Dugu Bo's abdomen.

Although it was faint, anyone with normal vision could see it.

This green light gathered into a mass at his Dantian.

That was not Dugu Bo's soul power, but active toxins manifesting on his body.

Ying Chengfeng stared without blinking, not missing a single detail.

He watched quietly, not thinking about anything else.

He wanted to finish observing before he started to ponder.

After a long while, Dugu Bo paused.

He had already contained the active toxins, but they had not condensed into a so-called Soul Core.

"Kid, where is the Soul Core you spoke of?" Dugu Bo was slightly dissatisfied.

However, he secretly suppressed a hint of excitement and agitation.

He felt that his condition had improved significantly, and there were even faint signs of his strength breaking through.

The key was that he felt his soul power toxins had become stronger.

Unlike before, when he always felt his poison should be more potent but couldn't unleash it.

It turned out the key was that he hadn't controlled all the poison.

Those uncontrolled toxins were attached to his meridians.

Every time he released soul power, they would linger in the meridians and refuse to leave.

But now, they were all wrapped in soul power, thoroughly assimilated, and under his control.

Although they hadn't condensed into a so-called Soul Core, he had indeed become stronger.

At this moment, Ying Chengfeng glanced at Dugu Bo and said, "The failure to condense a Soul Core is your own problem. You have no skill, yet you blame me?"

After speaking, Ying Chengfeng ignored him and asked Yu Feiyan, who was beside him, "Did you see anything?"

Yu Feiyan thought for a moment and said, "The diversity of life forms."

"Oh?" Ying Chengfeng felt slightly surprised.

Yu Feiyan continued, "His poison possesses life. I think my Ghost Fire should also be able to possess life."

Ying Chengfeng nodded and said, "If you can understand this point, then there is no problem."

As he spoke, Ying Chengfeng walked toward the herb garden in the valley.

Azure Luan Elder kept guard by his side the entire time.

Qian Renxue was also there, but she remained hidden and silent.

Just as he reached the herb garden, Ying Chengfeng looked back at Dugu Bo and Dugu Yan, who were about to follow.

He said indifferently, "You may leave."

Hearing this, Dugu Bo was stunned and said, "Aren't we supposed to cooperate with the research?"

Ying Chengfeng said, "The research is already finished. You may go."

From the very beginning, Ying Chengfeng had indeed intended to study Dugu Yan.

However, since Dugu Bo was so cooperative, he simply changed his research target.

And Dugu Bo was quite 'promising,' providing excellent material indeed.

At this time, Ying Chengfeng had already arrived at the herb garden, surveying the precious treasures of heaven and earth around him.

He didn't recognize many herbs, but he could still sense which ones possessed strong vitality.

Ying Chengfeng's gaze was immediately drawn to a red herb that looked similar to a cockscomb flower.

This herb contained vigorous vitality, and it seemed to possess a special flame power as well.

This special flame seemed as if it were undying and inextinguishable.

"Is this the Cockscomb Phoenix Sunflower? Legend says the phoenix can be reborn from the ashes; let me see if I can also turn a dead Ghost Fire into a living one."
