Human testing site.

The moment he said those words, the huge and empty laboratory suddenly fell into a dead silence.

The man who was two to three meters away was struggling, and the rustling sounds suddenly became particularly loud.

Ning Yu was expressionless, while Dr. Cheng was gasping for breath. His hands were hanging by his side, and he subconsciously clenched his fists.

"Then what are you going to do now?" Sinan stared at Ning Yu and asked slowly, "Turn me into a zombie too?"

Ning Yu seemed to be a little surprised by Sinan's steadiness, and answered casually, "No, I'd be crazy to do that."

But after a pause, he added, "But if it's necessary, I will."

"… What do you want to do?" Sinan frowned and asked.

Ning Yu smiled and said, "You're missing the point.

The problem is not what I want to do, but what I've already done. "

He got up and walked to the test bench. Sinan's eyes followed him. Ning Yu opened a device on the table that looked like a rice cooker, and used a pair of tweezers to pick up a blood collection tube. Sinan recognized the rice cooker, it was a blood centrifuge.

He suddenly lowered his head, and as expected, he found a cotton ball with blood stains fixed by medical tape on the vein of his right arm.

"This is your serum."

Ning Yu put the blood collection tube into the device and took off the cover. He said attentively, "I should have taken the blood from your left hand, but I heard from Romuir that you're a very outstanding individual combat expert … so I decided to take the blood from your right hand as an extra insurance."

Sinan clenched his right fist. Sure enough, there were sequelae from taking a large amount of blood at once. His fingers were cold, weak, and slightly soft.

"Romuir?

Did he tell you that my left and right hands are the same? "Sinan sneered," If you really want to be safe, you should take all four of my limbs in turn. "

Ning Yu replied, "If necessary, I will. You don't have to provoke me."

Sinan struggled against the handcuffs, which made a clattering sound, but the metal did not move.

Ning Yu didn't even raise his head. "Don't bother. It's made of stainless steel."

"…" Sinan finally gave up struggling. "Why did you take my serum?"

Ning Yu used an outdated method to manually calculate and remove the cover while recording something on a piece of paper. Unexpectedly, he didn't ignore the question, but answered it in an orderly manner.

"A few months ago, Romuir came here and used the semi-finished antibodies in his hands as bait to get us to pay attention to your traces along the coast.

His inexplicable stubbornness piqued my curiosity, until your people brought a group of survivors here … "

Ning Yu's calculation speed was very fast and didn't slow down because of his narration. "I asked Doctor Cheng and learned that when you first joined the survivors' camp, you claimed that you were bitten by a zombie and had a high fever that night."

"It was later proven that it wasn't a zombie, because I wasn't infected!"

"No." Ning Yu said, "I suspect that you were infected that time."

Sinan was confused. "… What do you mean?"

Ning Yu finally stopped calculating, picked up a string of pendants from the test bench, and shook them at Sinan.

"Are these your parents?"

— — It was the brass necklace that Sinan always wore.

"I'll pay you back."

Ning Yu looked at Sinan's expression and said, "It's just that after I saw this photo, I realized that you might be the one I've been looking for … Sorry, you're the experimental target that I've always suspected."

Sinan Xin said, "Suspected?"

"I've seen your parents." Ning Yu seemed to have seen through his doubts, but he didn't explain. Instead, he changed the topic.

"When I was sixteen years old, I went to A Country to study for a doctorate. Dr. Zhong Wan and his wife, Dr. Alisa Ferman, were my fellow apprentices.

At that time, we were studying a topic related to viral genetics under the same supervisor. The main idea was to use viruses to invade the genetic chain, promote modification and perfection, enhance the human genetic quality, and prolong the average life span. "

Sinan was caught off guard when he learned the real names of his parents. He was stunned for a moment.

"Since we're both Chinese, Dr. Zhong Wan gave me a lot of professional help, but the good times didn't last long.

A few months later, Dr. Zhong Wan was infected with a virus in an experimental accident and unfortunately died. Dr. Alisa Ferman took his body and you and disappeared from the research base. "

"… You …" Sinan's voice began to tremble. "I don't remember these. Tell me more. My parents …"

He was eager to know what his parents were like in his memory. He wanted to know more, more specific details, even if it was just a few insignificant childhood trifles.

However, Ning Yu was expressionless. He only answered him with six words, "No time, no interest."

"After the experimental accident," Ning Yu replaced the blood vessel and continued, "the research project was considered to be highly dangerous and confidential. Therefore, the military funded the entire research institute and began to search for Dr. Ferman's whereabouts.

The body of Dr. Zhong Wan she carried and the series of mutated behaviors produced by the body became a target of great interest to the military. "

Sinan noticed his choice of words. "Mutated behaviors produced by the body."

"A body can behave?"

"Although you were very young at that time, you should remember that there was always a bloodthirsty, wailing father who constantly tried to violently attack you and leave all kinds of wounds on your body.

Dr. Zhong Wan's behavior … I'm sorry, I don't want to call that thing Dr. Zhong Wan … After its behavior was monitored by the military, it was considered to be a great proof of virus research and a milestone.

It was also from that year onwards that the research base began to conduct live experiments under the command of the military. "

Dr. Cheng, who was listening by the side, was stunned.

Sinan closed his eyes. Countless disordered memories flashed through his mind. He opened his eyes and said in a trembling voice, "… White Eagle Base?"

"I don't know what it was later renamed," Ning Yu said, "because that year, I quit the research team and fled back to China."

Ning Yu took out the test tube with a pair of tweezers. Inside the test tube was the separated light yellow serum.

Sinan glanced at the man beside him who was groaning and groaning. Then, he looked at Ning Yu. "After you returned to China, you continued to conduct experiments on live humans and caused the virus to break out?!"

"Am I crazy?" Ning Yu said impatiently.

Sinan was speechless.

"To tell you the truth, at that time, all the capable countries in the world were conducting research in this area. Human beings' pursuit of 'better self' and 'longer life' was endless … The only difference was whether to insert the virus as a genetic modification method and whether to use live humans as test subjects.

By the way, I'm very sure that our country used chimpanzees, and I have no doubt that this would be a heavy foreshadowing before the disaster. "

Ning Yu walked to the side of the man who was turning into a zombie. He pushed out the air in the syringe and injected the biochemically synthesized serum into the man's blood vessels.

"As for me," he said, "I only began to use live humans as test subjects after the virus broke out … For example, the one in front of you."

The man's chest rose and fell violently, and he let out an inhuman scream. Dr. Cheng closed his eyes.

Sinan asked hoarsely, "Is this why Chen Yajing accepted survivors?!"

"Of course not.

But I do use opponents and lone survivors as test subjects, so it's harder to be discovered. "

Ning Yu finished pushing out the whole tube of serum and pulled out the needle, "For example, this person was mentally unstable because of too much pressure some time ago. Even if he went missing, it's easy to cover it up."

There was no fierceness in his tone when he said this. On the contrary, it was no different from "add an extra egg to your lunch box" or "the weather is a little cloudy today" — because it was so calm and natural that it sent a chill down her spine.

"… You injected him with the virus and let him be infected before testing the serum?"

Sinan asked incredulously, "Why didn't you use animals, or just use a simulated immune system?!"

Ning Yu did not answer him immediately. Instead, he picked up the camera and took a few photos of the man on the operating table. Then, he opened the notebook and began to quickly record.

The man had been completely infected, but he had not completely turned into a zombie.

The serum was quickly broken down, absorbed, and locked on to the antigen in his body. The invisible, smoky, and massive war began.

"The zombie virus does not infect animals. I think you've already noticed that."

Ning Yu said without raising his head, "No matter how the dose and toxicity are reduced, the only result of the zombie virus entering the body of an animal is immediate death. Only injecting the virus into humans and chimpanzees can produce a mutation effect. And I'm not running a zoo, so how can I catch so many chimpanzees?"

"As for the simulated immune system, it's even more ridiculous.

I need infected people under very specific conditions and during the transformation process. The requirements in all aspects are very high. Do you know how long it took me to build this laboratory?

Do you think I can build a supercomputer with my bare hands to do a simulated system? "

The man's screams suddenly became louder. His pupils suddenly dilated and then quickly closed again.

Ning Yu raised his eyes and looked at Sinan mockingly.

After more than ten seconds, Sinan softly squeezed out a sentence from between his teeth.

"How many people have you killed?"

Ning Yu said, "Who remembers this?"

"… If you're really so scientific, why don't you experiment on yourself first? Why don't you inject yourself with the virus first?!"

"If it's necessary, I will."

Ning Yu repeated this sentence for the third time. Compared to the previous two times, his tone and tone were not the slightest bit different. It was a sharp contrast to Sinan's anger.

"Now, please lie back down. The experiment has reached a critical stage."

Sinan's eyes were red. He gritted his teeth and leaned back in the recliner, almost forcibly suppressing his emotions.

"Ah … Ha … Ah —!"

The man suddenly struggled with all his strength. His bones and tendons were almost broken by the straps!

The explosive force at that moment was terrifying. Dr. Cheng reflexively took two steps back, but Ning Yu quickly stepped forward and turned on the flashlight.

He carefully observed the face in front of him, whose facial features were distorted and whose mouth was wide open. He didn't care at all that the man's teeth almost touched his hand several times.

Every minute and second felt like a century. After a few minutes, the man's pupils changed significantly. His eyeballs were rapidly filled with blood, and the veins on his neck were bulging!

Dr. Cheng stammered a few words, "Heart … Heartbeat!"

Ning Yu and Sinan turned their heads at the same time.

The straight line on the instrument that had become horizontal suddenly twisted, then jumped up and down and began to pulsate.

Ning Yu's hand loosened, and the flashlight fell to the ground with a clang, rolling under the operating table.

"Ahhhhh —" The man let out a heart-wrenching roar like a beast!

But everyone present could tell that the roar was different. The roar was not the mournful wail of a zombie, but the unconscious venting of a human being in a state of delirium.

Ning Yu rushed to the operating table and grabbed a syringe. Before he could run back, he heard the man's intermittent voice.

"Save … Save … Save …"

"He spoke." Dr. Cheng coughed and gasped. It was unclear whether it was extreme excitement, agitation, or fear. "He spoke!!"

It happened in just a few seconds.

The man clutched the bedsheet tightly. His whole body arched upwards like a balloon that had been blown to its limit. The next moment, it burst.

He fell heavily on the operating table. His mouth, nose, and ears were quickly filled with blood. In an instant, he stopped breathing.

The curve of the instrument calmed down again. It emitted a monotonous beeping sound that enveloped the dead silent hall.

Ning Yu gasped for breath. His whole body suddenly relaxed, and he took a few steps back in dejection.

"He … he's dead." Dr. Cheng's hands were trembling. He finished the examination with trembling hands and said, "The signs of zombification … zombification have disappeared. The serum … serum vaccine actually worked …"

Although it was only for a short moment, the serum did work.

The combined effect of the virus and the serum strangled this life, but the serum successfully stopped the virus from turning this body into a zombie!

Ning Yu raised his hand and covered his face tightly.

"… Impossible," Sinan murmured in a daze. "Impossible, how could I …"

Ning Yu wiped his face hard and said, "It's just as I expected."

Sinan and Dr. Cheng stared at him, but Ning Yu did not say anything. He turned back to the test table and quickly turned on the centrifuge. Only then did Sinan realize that there was a row of blood collection tubes on the test tube rack.

Ning Yu was too ruthless. It seemed that he had at least taken all of Sinan's blood while he was unconscious.

Sinan was light, and the total amount of blood in his body was not high. It was no wonder that Dr. Cheng thought that Ning Yu was going to kill him when he was watching from the side.

"I need a person," Ning Yu suddenly said in a low voice.

At first, Sinan did not realize what he was talking about, but in an instant, he realized what he was talking about.

"I want to remix the virus," Ning Yu repeated in a low voice. He looked at Sinan who was handcuffed to the recliner and said,

"I need a living person."

The two of them looked at each other for a moment. The gold-rimmed glasses blocked Ning Yu's gaze, and Sinan Sinan slowly felt a trace of coldness that he had never felt before.

Suddenly, a trembling voice broke the silence. "… There's … there's one here."

The two of them looked at the same time. Dr. Cheng staggered forward and blocked Sinan with his body. Then, he took out a handgun that he had hidden for a long time and pointed the muzzle at Ning Yu.

"There's … a living person here," he choked. The muzzle of the gun trembled, but his other hand was firmly pointed at himself. "You can experiment on him."
