Eventually, Qing Chen still refused to use Xiao Xuedou's bone powder on Jing Yan.

First, the success rate was too low. Not to mention that he hadn't researched the theory behind it, whether he could sort it out and find a practical method to integrate the two and superimpose their power was still unknown. The chance of failure was too high, making it pointless to even try.

Secondly...

Qing Chen held out his hand.

"Give it to me."

"What?" Jing Yan was taken aback.

"Lord Han's eyeball."

"...That's Lord Han's last remains! What, what, what are you going to do?"

"Don't worry, I won't mess around."

If Lord Han's eyeball still has some residual... maybe...

Various theoretical formulas flashed through Qing Chen's mind, but the premise was whether Lord Han's eyeball still had any source power.

Others might not know, because few people had discussed the concept of the Yu-level with Lord Han, what kind of existence people at that level were.

But Qing Chen, because of his rich theoretical knowledge and strong desire for knowledge, had discussed the situation of Yu-level experts with Lord Han.

Simply put, at the Yu-level, the power used is all driven by source power.

Only power involving the source can truly injure a Yu-level expert and truly kill one!

When Lord Han came to Qing Si County, he once declared that he would not die so easily, relying on his source power!

Below the Yu-level, very few people possess the ability to inflict damage involving source power, so naturally he didn't take the people of Qing Si County seriously.

It was just that Lord Han's condition at the time was that only his head remained, and his source power could only be used for passive self-preservation, unable to be used for offense.

This involved the problem of martial arts. Lord Han's skills did not include researching how to exert force and kill with only a head remaining.

Creating such a martial art was not impossible, but the time required would be measured in years, and the probability of success was very low.

According to Lord Han's own account, he had actually thought about studying martial arts that relied on a head to drive the source to inflict damage.

But thinking that he only had a few years left to live, and that he probably wouldn't be able to figure it out before he died, he gave up on the idea.

The reason for mentioning this was only because Qing Chen wanted to emphasize a concept: the source!

What is the source? The source of life is the source!

Lord Han once reached the peak, but then encountered an accident, falling from the peak to the half-step Yu-level, and then plummeting to this state.

Even so, that past peak had brought great accumulation to Lord Han.

The thickness of his source power was simply unmatched by ordinary Yu-level experts!

Simply put, the total amount was large, but his ability to exert force was not as good as others.

So he could only be beaten, unable to fight back, but also difficult to kill.

After all, the total amount was there.

Therefore, even Lord Han's eyeball had a probability of retaining source power.

If it were another Yu-level martial artist whose body was blown up, leaving only an eyeball, the eyeball would most likely not have any source power left and would be completely dead.

But Lord Han was different. Having once reached the peak, any part of his body might contain a huge amount of source power.

Therefore, even just an eyeball had a chance of retaining source power.

"Does that mean Lord Han is still alive?!"

"...Unfortunately, that statement is not valid."

Qing Chen also hoped that Lord Han was still alive, but simply having residual source power was far from enough.

It would also require various means to possibly pull Lord Han back from the depths of hell.

Even if everything went smoothly, Lord Han's lifespan would definitely not exceed one year... or even less than half a year, he would die in two or three months, and he would also kill...

Qing Chen glanced at Jing Yan.

"By the way, are you really willing to be my experimental subject? The risk is very high, you might die."

"Uh... can you reduce the risk?"

"Then I will definitely do my best in all aspects before conducting the experiment on you."

Qing Chen pushed up his non-existent glasses frames, acting serious: "After all, I am a theorist! I am not willing to do practical operations until the theory reaches its peak!"

"Brother Qing Chen is awesome! Brother Qing Chen is the best! From today on, I am a loyal fan of Brother Qing Chen! If you tell me to chop people, I will never chop watermelons, if you tell me to chop watermelons, I will never chop people!"

Qing Chen's face darkened. This guy's mouth was so unguarded, he seemed unreliable at all.

But it was rare for Jing Yan to be willing to be an experimental subject, so he naturally couldn't make any demands.

Having one was better than nothing. After all, this wasn't the underground stronghold. The Phoenix Organization didn't treat human lives as lives, so there were naturally many materials. He only had Jing Yan, who wasn't afraid of death, so what could he do? He had to make do.

After carefully examining Lord Han's eyeball, Qing Chen's expression became somewhat ugly.

"What's wrong?"

"...Preliminary results are out. Lord Han's source power still has some residual."

"Isn't that good news?"

"It's too little... and it's diminishing over time, although not quickly, but this is a normal phenomenon after the source collapses. If we want to save Lord Han, we need to act quickly. We don't have much time left."

"Then what are we waiting for?"

"...Jing Yan, I heard people say before that you were the one who analyzed the underground stronghold's passage, which means you should have good intelligence. But after getting in touch with you, I feel like you're not very smart."

Listen to that, is that human language?

Jing Yan felt depressed. He was anxiously trying to improve his strength. Didn't you know that if the game crashed, he would die? How could he not be anxious? How could he be wise?

Wise my ass, Jing Yan couldn't wait for a cheat to come and max out his character's strength!

Unfortunately, there was no way to do that.

Besides...

Jing Yan knew that he had analyzed the underground stronghold based on the actual situation and logical analysis.

But this scientific research stuff, he didn't even have basic knowledge of it, so how could he be wise?

However, a man must bow his head under the eaves.

Qing Chen was now Jing Yan's provider, his good big brother!

Whether he could turn the tables and get a full meal in the [United Society]'s prison depended entirely on Brother Qing Chen!

Now that Brother Qing Chen was educating him, what could he do? Admit his mistake!

"Brother Qing Chen is right. I'm actually very stupid. How can I be as smart as Brother Qing Chen! To tell you the truth, Brother Qing Chen is actually the object of my worship. Brother Ye? Just a brute!"

"Ah, this... I think Boss is quite amazing."

No way... Could it be that someone couldn't see that Brother Ye was actually not very smart?

Jing Yan quickly seized the opportunity to change the subject and stop dwelling on the problem.

Otherwise, pointing out that Qing Chen didn't actually have much of an eye for people would be too awkward.

Isn't it because he was so short-sighted that he accepted him as an experimental subject!

So, it's good to be short-sighted!

It's nice that even a piece of trash like him can shine!
