Outside the laboratory, the zombies kept scratching and slapping the tempered glass and the door. The cacophony of noise wafted into the room, not affecting the love of the two people inside in the slightest.

"It's an enzyme that has never been seen before. So far, no one has found this enzyme in the human body. ”

Chrissy's eyebrows fluttered, not at all like she was in a desperate situation. She happily handed the test report that had just come out of her hand to Lu Li, but unfortunately the latter pushed it away very simply.

Facing Chrissy's displeased gaze, Lu Li was very single-minded, and straightforwardly dispelled Chriss's desire to study and discuss with him.

"From childhood to adulthood, the creature has not passed once."

"Well, I overestimated your IQ."

Chrissy shrugged helplessly. There's nothing more frustrating for a researcher than discovering something new and not finding someone to share it with.

There was a brief silence in the room. A few minutes later, Chrissy couldn't hold back the surprise of discovering something new, and couldn't help but chat with Lu Li again.

"You should always know where the energy needed by the human body comes from, right?"

"Fat?"

"It's okay, it's not so stupid that it can't be helped."

Chrissy shook her head and sighed, "Fat is just one of the body's energy storage substances. In addition, proteins can also be degraded through guò to release energy. ”

Speaking of this, she blinked, stared at Lu Li with blazing eyes, and asked, "Do you understand?" ”

"Understood."

Lu Li replied casually in boredom. Angry that Chrissy kicked him hatefully, and blurted out a dirty word: "You understand a fart." ”

Without waiting for Lu Li to react, she raised her hand angrily and poked Lu Li's chest, and shouted, "The way for us to get out of trouble is you." ”

"Me?"

Lu Li was surprised. When Chrissy saw this, she immediately raised her hand in surrender. She raised her hand to stop Lu from leaving, and patiently explained with an expression that was defeated by your IQ.

"The main components of the human body are divided into muscle, fat, bones, internal organs, and so on. Although they have become zombies, their body composition is the same as ours. The kind of enzymes you have in your blood that can degrade proteins and fats in a short period of time, releasing a lot of energy. I, for example, just bit a little bit of skin on your arm and inadvertently ingested trace amounts of enzymes. As a result, I recovered my body. ”

The more Chrissy continued, the more surprised Lu Li became. At the end of the sentence, it dawned on him that Chrissy was trying to convey something. He asked uneasily.

"You mean to use this enzyme to degrade protein and fat at a high rate, so that the muscles on the zombies outside can be digested?"

"Yes, you've finally got the hang of it."

Chrissy was relieved. Lu Li pondered for a moment, stopped talking, and finally said in understanding: "Your idea is very creative. It's just not much of a feasibility. Take 10,000 steps back, this enzyme really works, so how long does it take? A day, or a week. I'm afraid we'll not make it that far. ”

"Of course, for an idiot, the idea is crazy."

Chrissy didn't care, and proudly lifted her delicate chin. She rolled her eyelids and sneered disdainfully, "Anything you can think of, I've already thought about it." That's not a problem at all. ”

She folded her hands, paced back and forth for two steps, and confidently explained, "They're dead, and they've been dead for days. This means that the muscles on their bodies have begun to decay. It's just that for some unknown reason this process has slowed down. All we need to do is add a little bit of weight to the scale. The result will be ......"

She drew a scale, lifting one hand and lowering the other. Before she could finish explaining, Lu Li already understood.

A piece of grass crushes a camel.

That's what happened. If the process of muscle decay is inhibited, then the balance in it is disrupted, and the process of decay becomes uncontrollable. Coupled with the chain reaction caused by the efficient degradation of enzymes, the process of spoilage is greatly shortened.

"What to do?"

Lu Li immediately asked. Chrissy confidently walked to the test table, picked up a syringe on it, and then turned to look at Lu Li's arm with a smile.

"In the first step, I need a lot of blood to extract enough of this enzyme from it. Muscle decay produces proteolytic enzymes as well as lipases. Since the virus inhibits the process of corruption in some unknown form. Then you need to use this special enzyme to break the balance. ”

After hearing this, Lu Li took the initiative to roll up his sleeves and stretched out in front of Chrissy: "As long as I guarantee that I can't die, I can smoke as much as I want." ”

Soon, Chrissy drew nearly ten milliliters of blood. She injected blood into a clean test tube and then drew another ten milliliters from a blood vessel in Lu Li's arm. In total, she took a total of 500 milliliters of blood. The clean test tubes were all used cleanly, and each contained 10 milliliters each.

Five hundred milliliters of blood were drawn at once, and Rao is Lu Li was strengthened by the human body enhancer, and he couldn't help but feel dizzy and almost fainted. He held on to the test table, rubbing his head weakly and complaining.

"You're welcome."

Chrissy didn't bother. She put the tube in the centrifuge, closed the lid, and pressed the switch. The centrifuge immediately buzzed slightly. About half an hour later, she opened the lid.

She took out a test tube and picked up the syringe that had been prepared to extract the clear liquid from the upper layer. Immediately afterward, she did the same and extracted the serum from another test tube. Next, after she instructed Lu Li to continue to separate the blood in the rest of the test tubes, she began to get busy.

After a whole afternoon, it was getting dark, and she finally stopped her work. She proudly stretched out a syringe in front of Lu Li and sighed slightly regretfully.

"It's a pity that the equipment here is a bit rudimentary, and there is a lack of high-precision centrifugal separators. Otherwise, the purity can be increased by more than 50%. ”

"That's it?"

Lu Li stared at the small speck in the syringe, about a milliliter, pale yellow, slightly turbid liquid, and asked in disbelief: "This is what kind of enzyme?" ”

"Not bad."

Chrissy pulled a bullet out of her pocket. She carefully applied the liquid from the syringe to the warhead. After a while, she handed the bullet to Lu Li and commanded.

"You should know how to use this bullet."

Lu Li nodded and took the bullet. He picked up the police gun that had been placed aside and placed the bullet in the chamber. With a thud, he looked up.

Capture the thief and capture the king first.

This is a truth that has remained unchanged since ancient times. Especially the group of zombies outside, it is obvious that the evolved zombie is looking at the horse. Kill that evolved zombie, and the rest is under control.

Lu Li's expression was very solemn. He knew he only had one chance. In order to hit the zombie, you have to open the gate. Once you miss, a flood of zombies will pour in. Even Superman can't stop him.

"Whew."

Lu Li took a deep breath. Suddenly, he felt a surge of vitality in his body, and his whole person became energetic. Both attention and the five senses have reached a new level.

Immediately, he didn't bother to study this strange phenomenon, rushed to the door, and jumped onto the laboratory table. He flew up, and the gate was overwhelmed, and he flew out with a click, smashing over several zombies at the door.

Taking advantage of the fact that the zombies had not yet filled the vacancy, he held his breath, raised his gun, aimed, and shot in one go. With a thud, the bullet jerked out of the muzzle and went straight through the hallway, through the window, and hit the evolved zombie in the chest.

The momentum of the bullet made it shake. Suddenly attacked again, it was furious. A low roar echoed. The zombie hordes suddenly went crazy.

They scrambled to the doorway, which was less than a meter away. In a short period of time, at least five zombies squeezed into the gate. They were stuck in the doorway, still trying their best to stretch out their unrestricted hands to Lu Li in front of them.

At this time, Lu Li had already jumped off the test bench. He stepped on the edge of the test table, resisting the zombie's onslaught, and asked anxiously.

"How much time does it take for that digestive enzyme to work?"

"According to my calculations, it will take about three minutes."

Chrissy looked calm, ignoring the zombies. But Lu Li didn't have such a good mood. The zombie hordes hit again and again, making him feel very difficult. And he noticed that these zombies had also evolved in some way.

For example, their power.

It was only the impact of less than ten zombies, and he was subjected to a huge backlash, and there was a faint tendency to be shaken away. He quickly calculated, and was depressed to find that he would only be able to support it for about three minutes at most, and then exhaust his body, which had finally recovered.

But at this point, he can't regret it. He stubbornly resisted the test table, and his heart was anxiously silent. A minute passed, and the zombie still angrily gave orders to command the zombie horde to rush into the laboratory.

Two minutes passed, and Lu Li was busy and caught a glimpse of the zombie and began to become a little agitated.

Three minutes passed, and the zombie suddenly let out a scream full of terror.

Lu Li heard this scream and hurriedly looked up. I saw that the zombie's whole body seemed to melt. Large swaths of rotten flesh fell like liquid. It tore at the carrion from its body desperately, as if doing so would stop it from rotting. It's a pity that this has accelerated the speed of corruption even more.

The effect is beyond Lu Li's imagination. Chrissy was a little surprised, but soon returned to normal. The two of them silently watched the zombie melt like a candle, and a smile appeared on their faces.

It worked!

Finally, it let out a terrified roar and turned to leave. With a roar, the zombie horde suddenly stopped attacking. It was as if they had received some kind of command, and the tide receded in an orderly manner.

As soon as the zombie group retreated, Lu Li's tense nerves relaxed. At this moment, Chrissy walked up to him, smiled strangely, and uttered a word.

"I need to do a full check-up on you."
