Zhou Rong's lips moved, as if he wanted to say something, but he held it back.

Chen Yajing immediately asked sensitively, "Do you want to say 'you are a group of lunatics'?"

Zhou Rong was indifferent, "I'm sorry, but I'm a soldier. I'm not educated enough to evaluate your behavior." He pointed to the first line on the first page of the death list and asked, "Who is this person?"

"… My husband."

Chen Yajing paused for a moment and sighed almost silently. "When my husband was in university, Ning Yu taught his class. That's how they got to know each other."

Chen Yajing's husband was at least 40 years old, which meant that when Ning Yu taught his undergraduate class, he was not even 15 years old. Zhou Rong didn't say anything, but asked, "What did you say about the vaccine research?"

Chen Yajing asked, "Tens of thousands of zombies are outside. Are you sure you want to talk about the vaccine at this time?"

Zhou Rong said, "If you really developed the antidote vaccine, at least at this moment, I will put the importance of the vaccine above all other tasks."

Chen Yajing looked at Zhou Rong for a moment and seemed to see something, "You are really a goal seeker …"

"Yes."

Zhou Rong admitted, "That's why I didn't immediately shoot you when I saw the death list.

Don't talk about other things, just talk about the vaccine. "

"Oh?

It seems that I can live for a few more minutes. "Chen Yajing slightly twitched the corner of her mouth and said dispiritedly.

"About the vaccine and Ning Yu …"

Chen Yajing changed her sitting position under Zhou Rong's impatient gaze and said slowly, "As I said before, when the zombie virus broke out, the institute sacrificed unimaginable manpower and material resources to do two things. The first was to repair the local communication system, and the second was to search for Ning Yu."

"Ning Yu once participated in the research of the zombie virus in A Country, and even met Romuir, who was the sponsor of the research.

After he quit the research and returned to China, he lived in seclusion in a rural area. After we took him back to the research institute, he came up with a terrifying idea. "

"He thinks that part of the reason why the zombie virus is so difficult to conquer is because it's too low-level. It keeps changing forms during the process of transmission, so it's very difficult to develop a vaccine that can lock it down.

For this reason, he decided to use genetic recombination technology to promote the evolution of the virus. When the virus reaches an advanced form, the speed of division and mutation will be relatively stable, and the development of a vaccine will go from 'almost impossible' to 'possible.' "

"He soon began the genetic recombination experiment against the virus, but the new virus needs to be tested, and we can't provide him with the necessary test subjects — gorillas or chimpanzees.

The only supercomputer in the research institute that can simulate the human immune system was smashed at the site of the disaster. Its system is too sophisticated, and we couldn't fix it even after a long time.

In a helpless situation, the research institute conducted the first drawing of lots … "

Chen Yajing took a deep breath.

"I've taken out the first five names on your list. My husband is one of them."

In the darkness, the air flow became very slow, and it was heavy in Zhou Rong's lungs and blood.

"If the research of the virus is exposed, this base will usher in an unprecedented large-scale panic and riots. The frightened people will be too scared.

So in the beginning, Ning Yu conducted experiments outside the base. After sacrificing dozens of volunteers, the evolution of the virus finally succeeded. The new virus has the characteristics of animal intelligence and hunting instincts. "

"But in an accident, the experimental zombie escaped and brought the new virus out. This is the origin of the low-level intelligent zombies you see outside."

Zhou Rong asked hoarsely, "What about the vaccine?"

"Ning Yu has tried to synthesize dozens of antibodies against the new virus after the evolution, but they all failed.

The closest example of success is right in front of you, and that's me. "

Chen Yajing pointed to her leg. "But the antibodies didn't completely kill the virus. The other four volunteers who were injected with me all became zombies. Only I was half-zombified."

"… So Ning Yu has been testing the improved antibodies on you?" Zhou Rong asked suspiciously.

"There are very few people who know the inside story. For example, Wan Biao is the backbone in charge of the base's security.

So in several armed conflicts between our base and the base next door, we captured a lot of prisoners of war. After that, we intercepted some … innocent survivors … "

Chen Yajing raised her hand and rubbed her face hard.

Zhou Rong finally understood. "So when Sinan and I were hijacked, Wan Biao stopped Yan Hao from killing the robbers because he wanted to bring them back to Ning Yu?"

"Yes," Chen Yajing said helplessly. "But Yan Hao's marksmanship is too fast."

Zhou Rongyi didn't know what to say.

"You can ask Ning Yu to explain the detailed theory. I will only briefly explain the vaccine plan to you."

Chen Yajing raised a finger. "In the first step, Ning Yu will first inject the new virus into the experimental subjects to infect them. Then, he will synthesize the antibodies and try to cure them.

If the first step shows signs of success, in the second step, he will inject the antibodies into me to verify.

As long as the degree of zombification can be reversed, it proves that the antibodies have achieved the final success. So far, I have been tested five times, and the antibodies are only one step away from success. "

"Ning Yu believes that Noah's serum is the key to this one step away.

If he can be used as a petri dish to cultivate the final vaccine to end this worldwide catastrophe, then there is no doubt that your Omega will be the savior of the entire human race. "

Zhou Rong's mind went blank. His finger on the trigger trembled slightly.

"In the near future, as long as we release the new virus to infect all the survivors and cure them with the vaccine, we can complete the complete purification of the virus on Earth."

Chen Yajing stared into Zhou Rong's eyes. In the darkness, her eyes flashed with a faint light. It was hard to tell whether it was sarcasm or sadness. "Whether you or Noah is willing or not, as long as there are antibodies in the serum … he will be the savior of the world."

Zhou Rong's ears were buzzing. He closed his eyes hard, as if he wanted to force himself to calm down. But the moment he blinked, Chen Yajing suddenly lowered her head and hid behind the experiment table.

"…!"

Zhou Rong rushed forward, but it was too late.

The cold and hard muzzle was pressed against the back of his head. Ning Yu's cold voice sounded, "Put down the gun, Captain Zhou. Bullets don't have eyes."

Zhou Rong looked forward. The dim light in the corridor shone on the hospital bed not far away, which was half covered by a white curtain. The iron bed frame faintly reflected a swaying figure.

Zhou Rong noticed something. He gently loosened his grip and the gun fell on the experiment table.

"Now," Ning Yu carried the medical kit and said impatiently, "Go out and deal with the zombies. Go out of the arsenal and turn left 300 meters away. Don't make trouble here … Oh!"

Ning Yu's throat was strangled from behind. At the same time, another muzzle was pressed against his temple!

"Put down the gun, Doctor Ning," Sinan said lightly, "Bullets don't have eyes."

Ning Yu's expression looked like he wanted to curse, but he was strangled by Sinan. His blood vessels were bursting and he couldn't even make a sound.

Zhou Rong turned around like a whirlwind, picked up Ning Yu and threw him to Yan Hao. The whole movement was done in one breath.

Yan Hao tacitly twisted Ning Yu's elbow and pressed it against the wall. Then Guo Weixiang squeezed into the room and pointed his gun at Chen Yajing, who had no choice but to stand up from the experiment table.

Then, Zhou Rongyi picked up Sinan.

Si Nan was almost 1.8 meters tall, but Zhou Rong picked him up in the air as if he were a child. He turned around and put him on the test bench. Then, he pressed the back of Si Nan's head and held him tightly in his arms.

"Si Xiaonan, my Si Xiaonan …" Zhou Rong repeatedly stroked his hair and rubbed his ears, as if to make sure that the treasure was not damaged at all. His voice was unsteady.

"Good, good, I didn't expect you to come and save Brother Rong. You're really good …"

Sinan was very comfortable in his strong palm. He squinted his eyes and said, "Oh … I also saved Yan Hao and Big Rooster just now. It's all good."

Yan Hao: "…"

Big Rooster: "…"

Guo Weixiang looked like he wanted to argue for himself, but Sinan looked up from Zhou Rong's arms and glared at him.

Guo Weixiang suddenly remembered the grenade he threw at the entrance of the experiment site. He instantly covered half of his mouth and didn't say anything.

Ning Yu politely struggled, but he gave up under Yan Hao's iron grip. He pressed his face against the wall and gritted his teeth. "Why are you here?

Didn't I tell you to stay in the laboratory? "

Sinan tilted his head and glanced at him. The meaning in his eyes was obvious: I'll stay wherever you want me to.

"… Idiot."

Ning Yu murmured and cursed. He was almost powerless. "The alloy door of the laboratory is very strong. Even if it's full of zombies, it won't be broken. There's also a spare warehouse behind it. It's enough for you to eat and drink for three months. It's enough for you to survive until the zombie wave passes …"

"Forgive me for being presumptuous," Zhou Rongyi put his arm around Sinan and said politely, "Doctor Ning, you're now a captive. It's better if you don't talk too much."

Ning Yu turned his face and closed his mouth tightly.

Zhou Rong carefully took out a fruit candy from his pocket and fed it to Sinan. He and Yan Hao quickly exchanged information about each other and the situation outside.

"Chun Cao and Da Ding are helping with the defense. But the civilian weapon inventory is limited. If the defense is broken, tens of thousands of zombies will all rush in."

Zhou Rong pondered for a few seconds and asked Chen Yajing, "I don't believe that your base doesn't have emergency measures. At least, you have a transfer tool, right?"

Chen Yajing looked at Ning Yu hesitantly.

Ning Yu was expressionless. He looked completely resigned to his fate.

The air fell into a deadlock of silence until a slightly hoarse voice sounded, "The secret of your base has been exposed. Miss Chen, there's no point in staying here."

Chen Yajing looked at the voice. It was Sinan who spoke with candy in his mouth.

"If my serum works, Ning Yu's experiment can continue anywhere.

If my serum doesn't work, Ning Yu will only be killed by zombies if he stays here. The door of the laboratory has been blown up by us. "

Sinan's right cheek was a little swollen because of the fruit candy, but his expression was very calm. "This base has sheltered tens of thousands of people. Now it's time for it to complete its mission. Get ready to evacuate."

This day was bound to come. In fact, Chen Yajing knew it even if he didn't say it.

Although the ending came earlier than the introduction of the vaccine, it was fated, and there was nothing that could be done about it.

Chen Yajing raised his head and made a decision for himself. Then he smiled tiredly. "Yes, you're right."

"Go out of this building and head north. There's a signal tower at the corner of the base. There's a helicopter hidden on the roof of the gray cement building nearby. It's specially prepared to protect Ning Yu on the day the base falls. You can let Ning Yu and Noah board the plane and evacuate first."

Chen Yajing tore a piece of paper and quickly drew a route map. "There are 68 buses and buses in the parking lot at the east end of the base. They can evacuate about six to seven thousand people at one time.

I'll arrange for the elderly, women, and children to board the buses first. If the fortification can't hold, the combatants will evacuate in shifts. "

She handed the route map to Zhou Rong with both hands and raised her chin. "I'll leave it to you, Captain Zhou."

Zhou Rong gestured with his finger on the map. He took a submachine gun from Guo Weixiang's tactical backpack and pointed it to the sky.

"Yan Hao and I will escort Sinan and Ning Yu to find the helicopter. Xiangzi, you take Miss Chen and that unlucky Brother Wan outside with the gun. Go to the front line to find Grassy Da Ding. Yan Hao and I will come to support later.

Any objections? "

Sinan suddenly glanced back at him, but the indescribable expression in his eyes was hidden in the dark underground.

Zhou Rong quickly took two steps forward and grabbed Sinan's hand. Their fingers intertwined and their palms pressed together.

However, he didn't dare to look at Sinan. He looked up and coughed.

"Very good. No objections. Let's go."

When they returned to the ground, Wan Biao had just woken up and was still dizzy. When he saw Zhou Rong, he immediately rushed over to fight him.

However, before he could take two steps forward, he caught a glimpse of Chen Yajing, who was pointed at by Guo Weixiang, and Ning Yu, who was pointed at by Yan Hao. He immediately stopped.

Guo Weixiang asked them to get into the nanny van and turned around to go back to the front line to support Grassy.

There was also a Jeep. Ning Yu consciously got into the driver's seat, and Yan Hao sat in the passenger's seat, pointing the gun at his head.

"What's the point of doing this?"

Ning Yu frowned and asked, "Even if I run into a tree now, you won't shoot. You will even jump over to protect me with your body. So, what's the threat?"

Yan Hao replied, "But if you run into a tree, Doctor Ning will be the first to die."

"Do I look like I'm afraid of death?" Ning Yu retorted.

Yan Hao pondered for a moment and agreed, "You're right." Then, he moved the gun down and pointed it at Ning Yu's crotch.

"…" Ning Yu's face kept twitching. He had no choice but to start the car. "… You win."

Zhou Rong seemed to have a premonition. He held Sinan's hand tightly in his arms and sat in the back seat without saying a word.

The Jeep shuttled through the secluded abandoned area in the dark of the night. It drove past unoccupied research buildings. Their heartbeats were close to each other as the car shook slightly. After some time, Sinan called out softly, "Zhou Rong."

"It's okay. Don't think too much," Zhou Rong also whispered, "Brother Rong just checked. This base is very sturdy. It won't be broken.

Even if it's broken, it doesn't matter. I'll retreat with the bus. Let's meet at the port. Brother Rong will get you a chocolate to eat … "

Zhou Rong buried his face in Sinan's neck and greedily sniffed the scent that was mixed with his own pheromone. Then, he lifted Sinan up and sat him down on his lap.

Sinan rested his elbows on Zhou Rong's broad shoulders. The two of them faced each other in the narrow back seat, their foreheads pressed against each other.

"Remember to call Sinan when you're in danger …" Sinan said softly, "As long as you call for me, no matter how far I am, I'll come and save you …"

Zhou Rong's eyes were bloodshot. He stared at Sinan's clear amber eyes.

"Hmm?" Ning Yu asked casually, "Isn't your name Noah?"

Sinan didn't even turn his head. "Who the hell is Noah? Forget about him."

Zhou Rong couldn't help but smile. Sinan lowered his head and kissed his thin and warm lips in the shaking car.

"Bang!"

The Jeep suddenly stopped. Everyone was caught off guard by the inertia. Yan Hao almost pulled the trigger. His face instantly turned pale. "What are you doing?!"

Ning Yu didn't care about his crotch at all. He stared at the flickering shadows in the front lights and squeezed out a few words from his teeth. "There's something."

Yan Hao reached out his hand to turn on the high beam, and the bright beam of light immediately extended out. In the vast darkness ahead, more than a dozen figures were staggering towards the jeep.
