I built the Black Tower City in Sumeru.

Chapter 31 This thing seems to be able to cure Demon Scale Disease.

Chen Bo entered the room and announced loudly and earnestly, "Senior Farusan, Senior Cole, I conducted a bio-alchemy experiment at home today and came up with something amazing."

Farusian paused for a moment: "Weren't you busy building your own mechanical doll these past few days? How come you're doing alchemy experiments again?"

"Senior Farusan, I'm a student of the Bio-Alchemy School. Mechanics is just a hobby; bio-alchemy is what I should be studying." Chen Bo casually made up a story, skipping over the topic.

Cole listened in stunned silence.

These past few days, Chen Bo has been learning about the Guardians of the Ruins from Farusan, designing blueprints, assembling machinery, and even finding time to conduct alchemy experiments.

I'm still at the stage of simply recognizing characters...

Does his day equal someone else's month? How can he learn so much?

"So, you've come to share your alchemical achievements with me?" Farusan asked.

"My bio-alchemy results this time are amazing, let me demonstrate." Chen Bo picked up a paper cutter from the table and made a very forceful and rapid cut on his left forearm.

A blood-red gash appeared in front of the two people.

"Anil! What's wrong with you?" Cole screamed in fright, dropping her pen. She frantically turned to rummage through the medicine box.

Farusan was also startled. She moved swiftly, snatching the knife from Chen Bo's hand: "Have you gone mad from doing research? Why are you hitting yourself like that!"

"Let me stop the bleeding first."

Farusan acted quickly, using a knife to cut open her skirt in preparation for bandaging Chen Bo.

Not far away, Ke Lai also ran over carrying an emergency medical kit.

However, when Farusan was holding the cloth to stop the bleeding from Chen Bo's arm...

The wound has completely healed.

It was as if it had never happened, as if what we just saw was just an illusion.

The arm was so smooth, without a trace of blood.

"You didn't see it clearly just now, did you? Let me demonstrate again."

Chen Bo took the prop from Farusan and once again forcefully slashed a hideous wound on his arm.

There was no bandage, no medicine applied. The gruesome wound seemed to have a life of its own, with the muscle tissue on both sides rapidly writhing and connecting.

In just one second, the wound closed completely, leaving not even a scar.

Smooth as ever.

Cole stood there, holding the first-aid kit, completely dumbfounded.

Farusan grabbed Chen Bo's arm and rubbed it repeatedly, even pinching it with her fingernails.

"Wait a minute, you mean you've already fused your own bio-alchemy materials?"

Chen Bo nodded: "After the biological experiment, I dipped my finger in the finished product to observe its properties. Then, the alchemical material fused into my body."

"Then, my body became what it is now. My body gained an extremely strong self-healing ability, and the toughness of my skin increased by at least ten times."

He looked at Cole, his tone becoming serious: "I think this might help Cole fight against the Demon Scale Disease."

The room fell into a deathly silence.

The Demon Scale Disease, a terminal illness that has plagued generations of people in Sumeru, seems to actually be solvable by this thing.

Farusan frowned. As a senior, she considered things more thoroughly and meticulously: "What is the origin of this material? Is there any rejection reaction? Is it repairing itself by overdrawing its life force, or by absorbing elemental energy?"

Do you feel very tired right now?

"There don't seem to be any side effects so far." Chen Bo knew the answer, but didn't know how to explain it.

This ability to repair comes from the power of destiny.

Abundant materials inherently possess extremely strong repair capabilities, and Nguyen Mai's bioalchemy endows these materials with terrifying adaptability.

According to the system's description, it can adapt to all living organisms.

After thinking about this amazing material, Chen Bo decided to characterize it as an accident. Chen Bo said, "This was a bio-alchemy I did casually. I just randomly added all the materials I found, and I didn't even recognize many of them."

"But this is the result for now. Should we let Cole try fusing it with my bio-alchemy material?"

Farussan pondered for a moment: "Research cannot rely on guesswork. Cole's situation is very complicated. Demonscale disease is not just a skin problem; the skin is just the surface. If we are unsure about the stability of this material, trying it rashly may backfire."

"After all, your situation is different from Cole's, and the changes that have occurred in you may not be repeated in Cole."

She looked at Ke Lai, then at Chen Bo, and suggested, "How about this, first cut off a small piece of Ke Lai's skin and let it come into contact with your bio-alchemy material to see if there's any rejection reaction."

"Cut off a piece?" Upon hearing this, Cole's body trembled violently.

She instinctively took a few steps back, bumping her back against the bookshelf.

Memories of being locked in a laboratory, of having one's body cut by cold instruments, of being injected with demonic remnants, and of various potions surged forth like a tide.

"No...no." Cole's face turned pale, and her breathing became rapid.

Farussan realized she had said the wrong thing.

What he had just said probably reminded Cole of his childhood memories of being used as a test subject by the doctor.

Looking at Cole's slightly trembling shoulders, she seemed frightened.

Farusan rushed over and pulled Cole into her arms.

"It's alright, child, it's all over now."

Farusian gently patted Cole's back and whispered comfortingly, "We won't do those messy experiments anymore, I promise, we won't do them again."

Cole snuggled closer to Farusan, feeling the warmth emanating from her, and her emotions gradually calmed down.

"It's alright, Senior Farusan, the experiment still needs to be done."

Although there was still a slight tremor in her voice, Kolei's attitude was resolute: "I will actively cooperate with the treatment. Master Tinari said that avoidance and resistance will not cure the disease. As long as I can be cured of Demon Scale Disease, I can overcome anything."

Chen Bo stood aside, watching this strong girl who was heartbreaking to see.

Chen Bo knew for certain that there were no side effects.

Because the system didn't say, and if it didn't say, then it doesn't exist.

However, he had no reason to convince Farussan and Cole that there were no side effects.

"Let me observe myself for a while first," Chen Bo broke the silence. "Let me see if this stuff has any hidden side effects. Once I'm completely sure there are no problems, I'll consider letting you try it."

After thinking for a moment, Farusan said, "In that case, let me give it a try too."

"I have the Eye of God, and my physical fitness and elemental resistance far exceed those of ordinary people. If this thing really consumes life force or has other negative effects, I can clearly sense it."

Cole immediately stopped her, saying, "Senior Farusan, you don't need to take this risk with me."

This is her business; how could she let Senior Farusan test the medicine on her?

"What do you mean by adventure? This is called rigorous academic verification." Farusan raised her chin, her expression serious. "Medicine and mechanical arts are the same; both require bold hypotheses and careful verification. Since Anil used it without problems, there's no reason for anything to happen to me."

Chen Bo knew there were no side effects, so he wouldn't try to persuade Farusan to be careful or anything like that.

He took out a petri dish, dipped a small amount of the material into a utility knife, and handed it to Farusan: "Just touch it with your finger."

"It's pretty simple." Farusan stretched out her finger, ready to touch it.

Unexpectedly, before Farusan could touch the material, Cole grabbed the paper cutter and touched the material.

"Senior Falusan, let me do it."
