Chrissy paused, but finally tried to stay calm, shaking the syringe in her hand: "This is the virus stock extract from that ordinary zombie. I want to inject the virus into you......"

Before the words fell, Chen Yuxin, who was busy preparing practical equipment, was stunned, and hurriedly turned around and denied: "This is absolutely not good." It is against medical ethics to use humans to perform human realization. I don't allow you to take such risks unless you first do pharmacology, toxicology, etc. ”

"We don't have time."

As if they had a heart in their hearts, Lu Li and Chrissy looked gloomy at the same time. Chen Yuxin was stunned, and then still insisted on her own opinion.

"Even so, I won't allow you to take any chances."

Speaking of this, her tone softened, and she almost pleaded and persuaded: "We can shorten the process of real yàn, first perform real yàn on the mouse, and observe for three days to get the number of jù." Then find a way to enter the zoo, catch a few monkeys for realization, and observe for another three days. If it's all right, let's do the human body again. Six-day ...... It should be in time. ”

"It's been too long."

Lu Li shook his head, and firmly rejected Chen Yuxin's suggestion: "The speed of zombie evolution has exceeded imagination. It's only been two weeks since the virus broke out, and there's already a guy among them who is as tough as the corpse next door. I don't dare bet on whether the zombies will give us enough time to work out the corresponding countermeasures. ”

Chen Yuxin was speechless. She had already seen the corpse of the fortified zombie. Indeed, the corpse that was supposed to decompose stopped the decay process and instead developed a crust similar to the cuticle.

When collecting the number of specimens, she saw Liu Qiang use a saw as if sawing wood, and it took a lot of effort to barely cut through this layer of hard skin. The keratinized crust toughness is self-explanatory.

With such a tough crust, the firearm that humans rely on has almost lost its maximum effect. If such a strengthened zombie hordes hit the human defenses...... Chen Yuxin couldn't help but think of that apocalyptic scene in her mind.

In the rain of bullets, zombies rushed all the way to the rain of bullets. The dense bullets hit them, and they didn't hurt at all, except for making them shake their bodies. They rushed into the defensive line. The survivors were scratched and bitten by them in their wails and turned into zombies. City A became hell in the blink of an eye.

Subconsciously, she covered her mouth, took two steps back with a panicked face, and touched the real platform behind her. The tremor made the instrument hum. She hurriedly turned around and held down the real platform.

Her face was very bad. She thought back to her previous painful encounters.

Chrissy and Lu Li glanced at each other, and did not disturb Chen Yuxin, who was caught in painful memories. Lu Li sat down again and stretched out his right arm in front of Chrissy. The latter understood, disinfected it with an alcohol swab, and then picked up the syringe. The needle is pierced into the blood vessel, and the gray virus stock solution is slowly injected.

After a while, Chrissy pulled out the needle, turned around and picked up the notebook and pen on the table, and began to observe. Five minutes later, she immediately threw out a barrage of questions.

"Dizzy or not?"

"Do you have a fever?"

"How does it feel?"

“……”

Lu Li carefully felt the subtle changes in his body and answered the questions raised by Chrissy truthfully. The two asked and answered, and they seemed to have a very tacit understanding.

At this time, Chen Yuxin had already broken free from the painful memories. She was pale and covered in a fine layer of sweat on her forehead. Seeing the two of them looking focused, she couldn't help but laugh bitterly at herself.

I'm obviously troubled. At a time like this, do we still need to be ethical?

She quietly turned around and began to resume her previous work. But she was a little absent-minded at the moment. The tacit understanding between Lu Li and Chrissy made her ashamed. A thought came to my heart for no reason.

"Things gather by like, and people are divided by groups."

Only people like Lu Li and Chrissy who are not bound by common sense can be so powerful, right?

After more than an hour, Lu Li and the two stopped talking. Chrissy instructed without looking back, "Give me a clean test tube and syringe." ”

Chen Yuxin was stunned, and hurriedly gathered her mind and handed over the things that Chrissy had ordered. Chrissy took the syringe and needle, quickly pierced the needle into the blood light of Lu Li's right hand, and drew about ten milliliters of blood from it.

After collecting the blood, she immediately turned around and handed the test tube to Chen Yuxin: "Do your best to complete the analysis." The report was out and sued me as soon as possible. ”

"Hmm."

Chen Yuxin took the test tube, turned around and walked to the analyzer, and began the preliminary treatment of the blood. On the other side, Chrissy continued to ask Lu Li how he felt.

Time flies. More than two hours later, Chen Yuxin got the analysis report. She handed the analysis to Chrissy. The latter took the report and glanced at it quickly. Finally, the gaze is fixed on one of the columns. She was slightly stunned and subconsciously frowned.

"How can the white blood cell content be so high?"

The importance of white blood cells to the human body is self-evident. As the first line of defense against diseases, white blood cells can engulf and digest germs and viruses that invade the human body. The total number of white blood cells in the average person is basically the same. The total amount of white blood cells in the blood is nearly 20 times higher than normal.

Lu Li heard Chrissy muttering to herself, and her heart suddenly felt bad. He immediately asked, "How?" ”

"I'm not sure yet."

Chrissy shook her head and raised her eyes to look at Lu Li: "I need a more detailed number." ”

After saying that, she turned her head to look at Chen Yuxin and instructed, "Prepare it for me, and prepare it immediately." ”

Chen Yuxin nodded and immediately began to prepare. At this time, Chrissy said to Lu Li again, "I need to collect samples from all over your body. ”

"Okay."

Lu Li was very crisp, sat on the chair and rolled up his sleeves. Chrissy turned around and took a scalpel and collected samples of blood, skin, and so on from his hands and feet.

Scientific practice is very cumbersome, especially the extraction of a particular substance. For a whole afternoon, the three of them stayed in the real room and did not go out. Especially Chrissy and Chen Yuxin.

The two goddesses were focused, sometimes talking briefly, sometimes arguing for a while. Soon they shook hands and made peace, concentrating on analyzing and studying the samples collected from Lu Li's body.

Unlike the two daughters, Lu Li is obviously much more relaxed. He was not idle either. At Chrissy's urging, he rummaged through the various instruments stacked at the foot of the wall, then turned on the power for simple adjustment, and finally sent them to the real platform.

The hard work of the three was not in vain. At dusk, Chrissy got the latest results. She stared intently at the results in her hand. Gradually, a touch of joy welled up between the brows.

"The results are in."

Chrissy was relieved, and her tone was very relaxed: "The white blood cells in your body have mutated. This mutated white blood cell is capable of engulfing the zombie virus. So you'll be safe and sound after being infected with the zombie virus. ”

Lu Li thought for a moment and asked hesitantly, "Can they detect this mutated white blood cell in my body?" ”

"Nope."

Chrissy shook her head: "There is no evidence yet that they are capable of detecting the inside of the human body. But I guess it's the virus that has mutated and developed intelligence. At the same time, it also produces instinct-like abilities. ”

Speaking of this, she seemed to guess that Lu Li Tie would definitely not understand, and explained in detail: "Modern science has proven that a large number of unintelligent creatures may produce group intelligence. For example, ants, bees and other insects. The same should be true of this zombie virus. This also explains that they have basic thinking skills. ”

"It's because they generate the wisdom of the crowd that they're the weakness. Once separated, it falls below the level of generating the wisdom of the crowd. Then they will become zombies who only act on instinct......"

As soon as she said this, Chrissy and Lu Li's faces changed at the same time. The two looked at each other, and both saw the same meaning in each other's eyes.

The scales of the Goddess of Victory have begun to slowly tilt in favor of humanity.

Chrissy quickly grabbed her pen and wrote it in her notebook. After a while, she raised her head with her eyebrows fluttering and cheered uncontrollably.

"I'm sure you're not a virus vaccine, you're a virus buster."

Without waiting for Lu Li and Chen Yuxin to speak, she explained with a little excitement: "The main mechanism of action of the mutant white blood cells in your body is not to phagocytose viruses and produce antibodies, but a target cell. The virus enters the body, is attracted to this target cell, and is then engulfed and digested. It is precisely because of this target cell that it has a fairly strong attraction to the virus. Therefore, those zombies who have developed wisdom will instinctively feel the danger and will turn away from you. ”

At this point, she came to a categorical conclusion: "Give me a little time." I was able to grow large numbers of these mutant white blood cells. At that time, no matter what course the zombie evolves to, it will no longer be a problem. ”

"How long will it take?"

Lu Xuan was lightly relieved and quickly asked, "Is a week enough?" ”

"Three days, give me three days."

Chrissy raised her delicate chin and looked confident: "This time is different from last time. Extracting mutant white blood cells is relatively simple. The main reason is that the preparation of the medium is more complicated. Don't say it's me, even Yuxin can do it. ”

With that, she quickly wrote down more than a dozen materials on the blank page of the notebook, then tore them off and handed them to Lu Li: "You help me find all these things in the past two days, the more the better." ”

"Okay."

Lu Li nodded happily and turned around and walked outside. As soon as he took a few steps, Chrissy stopped him again: "If you can, catch a few more live zombies for me." I need to do clinical practice on them. ”

……

At night, Lu Li summoned Liu Qiang and the others. He told the three of them what Chrissy had discovered. Knowing that this disaster was coming to an end, the three of them looked a little excited.

Lu Li was silent, allowing the three of them to digest the good news. Finally, he took out the list that Chrissy had given him.

"We've had a busy couple of days."
