Chapter 702 - 573: How Could You Do This!

"Ah?"

Zhang Su was momentarily stunned, then swiftly dashed to Liu Tianji’s bedside, grabbing the hand that had been previously severed with lightning speed. He squeezed it; it was elastic and warm!

"A real hand?"

Shocked, Zhang Su looked at Liu Tianji, noticing the astonished expressions on the faces of several people around him. He quickly suppressed his emotions.

"It’s a real hand; my limb has regenerated, Brother Su, can you believe it?"

Liu Tianji’s face was about to burst with joy; although he still saw things in black and white, having his hand grow back was a divine blessing!

Can you believe it?

Of course, why not with it right in front of you...

"Why did this happen?"

Zhang Su wasn’t immediately delighted. He knew about Chen Hanzhou’s current situation, naturally being cautious about the subsequent reactions of others bitten, fearing they might have similar experiences. He turned to look at Ke Zhiyu on the opposite bed.

"I... I’m recovered too, King Yama, thank you, thank you for saving me!"

When Ke Zhiyu saw Zhang Su looking over, he quickly rotated his recovered hand. He would never forget Zhang Su’s decisive cut back then; if not for promptly severing the affected area, he might have perished. Now, not only reborn, but his hand has grown back, truly a miracle!

"I’m happy for you both."

Zhang Su also inspected Ke Zhiyu’s hand, undeniably a new hand.

As he spoke, Zhang Su suddenly sensed a special emotional wave.

The excitement of Liu Tianji and Ke Zhiyu was intense and identifiable, Duan Wuhu was utterly baffled, filled with curiosity and confusion. Even Xie Yanshan at the desk was perplexed and contemplative, his thoughts a tangled mess.

These emotions could be explained, but what was that hint of urgency about?

Why urgency? What needs rushing?

"Being able to regenerate limbs is indeed worth celebrating, but I want to know... Dr. Fu, Dr. Xie, how was this achieved? Such a significant breakthrough, if the principles are unknown, isn’t it a pity!"

Zhang Su’s gaze landed on the two researchers.

"Well..."

Xie Yanshan politely smiled at Zhang Su. Earlier, Liu Tianji caught him as soon as he entered, without a chance to greet. Looking at Zhang Su, his face was full of contemplation mixed with embarrassment: "Well, this phenomenon might relate to omnipotent stem cells, but I have no definite idea."

Limb regeneration has always been a challenge in human medicine, stuck in the experimental stage before the disaster with no clear breakthrough.

The experiences of Liu Tianji and Ke Zhiyu were quite explosive for humanity, yet in the natural world, it’s barely significant. Leaving plants aside, even among animals, many can regenerate limbs, relying on omnipotent stem cells and pluripotent stem cells.

"Could it be the effect of the Corpse Transformation Inhibitor?"

Zhang Su continued to inquire, shifting his gaze to Fu Weijun.

Feeling Zhang Su’s gaze, Fu Weijun’s heart raced twice, his hand gripping the wheelchair handle tightened slightly.

"Dr. Xie’s conjecture is reasonable. Based on my hypothesis... Limb regeneration might involve some association between the Zombie Robot within the two individuals and human cells, not ruling out the Corpse Transformation Inhibitor as a catalyst. As for the specific reason, precise instruments are needed to ascertain it."

Fu Weijun finished, regretfully spreading his hands, the meaning clear: given current hardware conditions, the research had reached its limit.

"Oh? Is that so?"

Zhang Su maintained his composure, all emotions vanishing, allowing him to better perceive the emotions of people around him. Amidst mixed waves, he didn’t sense regret, yet he detected Fu Weijun’s inner tension and panic.

Previously, with such a significant discovery, Fu Weijun would surely be excited and eager to delve deeper into the research. But now, impatience, tension, confusion marked his responses, which clearly didn’t seem right!

Xie Yanshan nodded along with Zhang Su’s inquiry: "Yes, without entering the micro world, we remain superficial, relying on crude experiments to explore slowly. It’s not only inefficient, but many experiments are too risky to attempt, yielding no results."

Zhang Su remained silent, instead looking at Liu Tianji: "Xiaoliu, let me ask you, besides injecting the Corpse Transformation Inhibitor, did the two doctors administer any other drugs to you?"

With this question, the atmosphere in the room instantly became somewhat stiff.

Ideally, this query should be directed at the rescuers rather than the patients, but Zhang Su felt no need for courtesy with someone he suspected.

Duan Wuhu sensed the off atmosphere, his curiosity and contemplation faded from his face, he looked at Fu Weijun with an inquisitive gaze, only to feel a chill internally on a single glance, thinking ’Oh no.’

He and Fu Weijun met during the apocalypse, having spent significant time together, understanding each other well, their daily interactions full of rapport. So, with merely a look, Duan Wuhu realized Fu Weijun was hiding something!

"Other drugs? There were indeed..."

Liu Tianji raised his newly grown hand, pointing at Fu Weijun: "Before you left, Dr. Fu brought us some medicine, but nothing special, just some painkillers."

"Painkillers?"

Zhang Su turned to Xie Yanshan, asking: "Dr. Xie, do Liu Tianji and Ke Zhiyu require painkillers?"

"Um..." Liu Tianji raised his hand, answering first: "Brother Su, I actually don’t need them because I still don’t have any sensation of pain, but Big Dumb still feels pain."

’Big Dumb,’ Liu Tianji’s nickname for Ke Zhiyu.

"As far as I know, no..."

"No need to ask anymore!"

Fu Weijun suddenly lifted his head, took a deep breath, seemingly making a decision, candidly saying: "I gave them something unusual to consume, which led to this incident!"

After his words, everyone was left speechless.

"This, ah, this is..."

As those who took the medicine, Liu Tianji and Ke Zhiyu stared at each other, feeling their blood chill slightly.

Xie Yanshan was dumbfounded, looking at Fu Weijun, thinking how bold this was!

Duan Wuhu covered his face with his hand, feeling helpless, alongside some internal panic.

Zhang Su pursed his lips, frowned at Fu Weijun, who was tightly gripping the wheelchair handle: "Fu Weijun, Fu Weijun, tell me, have you forgotten my words? Didn’t I say, under no circumstances should we conduct any experiments on our own people?"

"The Corpse Transformation Inhibitor can still be considered treatment, but what did you say earlier, give them something unusual arbitrarily, what is it, huh? Surely even you don’t know what effect that stuff has, yet you dared to feed it to them, have you lost your mind?"

Limb regeneration is indeed noteworthy, but Zhang Su found Fu Weijun’s actions utterly reprehensible, requiring immediate prevention.

"That’s right! Weijun, how can you be so reckless?"

Duan Wuhu quickly chimed in, angrily pointing at Fu Weijun: "Your reckless actions violate the spirit of research, you’re playing with lives here, quickly apologize to Brother Zhang and offer restitution to these two young brothers!"

Duan Wuhu acted like a parent confronting a child who caused trouble outside, while Fu Weijun was that troublemaking child, receiving a thorough scolding. There’s no justification for this; if an error isn’t promptly acknowledged, the ramifications might be hard to manage.

"Well... my hand is indeed healed, so perhaps it was a fortunate mistake, but seriously... you shouldn’t just feed us anything randomly, you, you, you don’t take us seriously at all!"

Liu Tianji initially thought his limb regeneration was thanks to Fu Weijun, so why harbor so much resentment? Yet upon seeing Zhang Su’s gaze, he immediately changed his tune, wrong is wrong—and whether limb regeneration resulted from some peculiar drug remains uncertain.

Ke Zhiyu’s expression was complicated, as both a victim and a beneficiary; he wanted to say something, but given his humble status, he ultimately raised his head to the ceiling, saying nothing.
