Chapter 586

"Huh?"

Zhang Su was stunned for a moment, then lunged toward Liu Tianji's bed in a flash, grabbing the palm that had been chopped off earlier. He squeezed it—it had elasticity and warmth! "A real hand?"

Zhang Su looked at Liu Tianji in shock. Seeing the expressions of astonishment appearing on the faces of the few people around, he quickly suppressed his emotions.

"It's a real hand. My severed limb has regrown. Brother Su, can you believe it?"

Liu Tianji's face was practically blooming. Although his eyes still saw things in black and white, the fact that his hand could grow back was already a heaven-sent grace! Can he believe it? Of course he can; it's right in front of his eyes, why wouldn't he...

"Why did this happen?"

Zhang Su wasn't happy right away. He knew about Chen Hanzhou's current situation and naturally would be vigilant about the subsequent reactions of those bitten like Liu Tianji, fearing they might also experience similar situations. He turned to look at Ke Zhiyu on the opposite bed.

"I, I'm also better. King of Hell, thank you, thank you for saving my life!"

Seeing Zhang Su look over, Ke Zhiyu hurriedly rotated his recovered palm. He would never forget Zhang Su's decisive strike back then. If it hadn't been for the timely amputation of the affected area, he might have already kicked the bucket. Now, not only had he been reborn, but his hand had even grown back. It was a genuine miracle!

"I am happy for you both."

Zhang Su also checked Ke Zhiyu's hand—it was the real deal, a brand-new palm.

While speaking, Zhang Su suddenly sensed a trace of a special emotional fluctuation.

Liu Tianji and Ke Zhiyu's excitement was quite intense and almost effortless to identify. Duan Wuhu was like a monk confused by a second monk, full of curiosity and bewilderment. Even Xie Yanshan, standing in front of the desk, was confused and thoughtful, his mind a tangled mess.

These emotions were all easy to explain, but what was that faint trace of urgency?

Why be in a rush? What was there to be in a rush about? "Being able to regrow a severed limb is indeed worth celebrating, but I want to know... Dr. Fu, Dr. Xie, how was this achieved? Such a major breakthrough—if we don't know the principle, it would be a pity!"

Zhang Su's gaze fell on the faces of the two researchers.

"This..."

Xie Yanshan smiled politely at Zhang Su. He had been interrupted by Liu Tianji as soon as the other party entered and hadn't had a chance to greet him. Seeing the other party looking at him, he wore a face full of contemplation, mixed with embarrassment, "This, this phenomenon should be related to totipotent stem cells, but I don't have a clue about the specifics."

Regrowing severed limbs had always been a difficult problem that human medicine wanted to conquer, and until the disaster broke out, it had remained at the laboratory stage without any significant breakthroughs.

Liu Tianji and Ke Zhiyu's encounter was quite explosive for humans, but looking at the natural world, it was nothing at all. Not to mention plants, even among animals, there were many players capable of regrowing severed limbs, relying on totipotent and pluripotent stem cells.

"Could it be the effect of the Zombie Transformation Blocking Fluid?"

Zhang Su pressed on, while shifting his gaze toward Fu Weijun.

Feeling Zhang Su's gaze, Fu Weijun's heart skipped two heavy beats, and his hand gripping the wheelchair armrest tightened by two degrees.

"Dr. Xie's inference is very reasonable. According to my speculation... the regrowth of the severed limb should be that some kind of connection occurred between the zombie robots in their bodies and the human cells. It cannot be ruled out that the Zombie Transformation Blocking Fluid played a catalytic role. As for the exact reason, it would require precision instruments to detect the results."

After Fu Weijun finished speaking, he spread his hands with slight regret. The meaning was clear: with the current hardware conditions, the research had reached a dead end.

"Oh? Is that so?"

Zhang Su kept his heart peaceful, and all emotions vanished. This allowed him to perceive the emotions of the people around him more accurately. Among the complex fluctuations, he did not sense regret, but he did detect Fu Weijun's inner tension and panic.

In the past, if there had been such a major discovery, Fu Weijun would definitely have been excited and thrilled, and would have been impatient to conduct in-depth research. But what was this reaction now? One moment anxious, one moment nervous, one moment panicked—this emotion was clearly not right! Xie Yanshan nodded along with Zhang Su's question: "Yes, without entering the microscopic world, we remain on the surface, only able to rely on rough experiments to slowly grope around. Not only is the efficiency slow, but many experiments simply dare not be attempted, and no results can be obtained."

Zhang Su didn't chime in, but instead looked at Liu Tianji: "Little Liu, let me ask you, besides injecting you with the Zombie Transformation Blocking Fluid, did the two doctors use any other medicine?" As soon as the question was asked, the atmosphere in the room instantly solidified.

By rights, this question shouldn't be asked to the patient, but rather to the rescuer to be more polite, but Zhang Su had no need to be polite to a suspect.

Duan Wuhu felt that the atmosphere was wrong. The contemplation and curiosity on his face faded, and he looked at Fu Weijun with an inquiring gaze. As a result, with just one look, his heart skipped a beat, and he secretly thought, "Oh, no."

He and Fu Weijun had met during the apocalypse and had spent a long time together. They knew each other very well, and their daily communication was very tacit. Therefore, with just one look, Duan Wuhu could see that Fu Weijun was hiding something! "Other medicine? There was..."

Liu Tianji raised his regrown palm and pointed at Fu Weijun: "Before you left, Dr. Fu came to give us some medicine, but it wasn't anything special, just some painkillers."

"Painkillers?"

Zhang Su looked at Xie Yanshan and asked: "Dr. Xie, do Liu Tianji and Ke Zhiyu's conditions require painkillers?"

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

Big Dumb, the nickname Liu Tianji gave Ke Zhiyu.

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

"No need to ask!" Fu Weijun suddenly raised his head, took a deep breath, as if he had made up his mind, and said frankly: "It was I who gave them something unusual to eat, which is why this happened!"

After the words fell, everyone on the scene was speechless.

"This, ah, this, this..."

As the parties who took the medicine, Liu Tianji and Ke Zhiyu stared at each other, only feeling their blood run a little cold.

Xie Yanshan looked at Fu Weijun, dumbfounded, thinking to himself that this was too bold!

Duan Wuhu covered his face with his hand, feeling very helpless, and his heart was also a bit panicked.

Zhang Su pursed his lips and frowned at Fu Weijun, who was gripping the wheelchair armrests tightly: "Fu Weijun, oh Fu Weijun, tell me, have you forgotten my words? Did I not say that I absolutely do not allow any experiments on our own people?"

"The Zombie Transformation Blocking Fluid could at least be seen as treatment. What did you just say? You gave them something unusual to eat. What was that, huh? You definitely didn't even know what that thing's efficacy was, yet you dared to feed it to them randomly. Are you crazy?"

Regrowing a severed limb was indeed worth paying attention to, but Zhang Su felt that Fu Weijun's behavior was very malicious and needed to be stopped immediately.

"Yes! Weijun, how could you mess around like this!"

Duan Wuhu hurriedly chimed in, pointing angrily at Fu Weijun: "Messing around like this goes against the spirit of scientific research. You are playing with human lives! Why don't you hurry up and apologize to Brother Zhang, and, and apologize to these two little brothers!"

Duan Wuhu was like a parent whose child had caused trouble outside, and Fu Weijun was that troublesome brat. He was scolded from head to toe. This matter was definitely not justifiable; if he didn't admit his mistake quickly, he was afraid it wouldn't end well.

"This... my hand is indeed better, and it can be considered a stroke of luck. Sigh, this matter... no matter what, you shouldn't feed us random things. You, you, you took us too lightly!"

Liu Tianji had originally thought that his severed limb regrowth was all thanks to Fu Weijun, so why bother about so much? But when he saw Zhang Su's eyes, he immediately changed his tune. Wrong is wrong, not to mention whether the severed limb regrowth was really because of some strange medicine was still unknown.

Ke Zhiyu's expression was complex. As a victim and also a beneficiary, he wanted to say something, but his status was too low, so he finally raised his head to look at the ceiling and said nothing.
