1 + 1 is equal to two, but sometimes qualitative change will lead to leap quantitative change.

The skin of level-2 zombies is much stronger than that of level-1 zombies. Ordinary daggers can't hurt him. Even guns can only pierce the surface. As for internal organs, it's even more wonderful.

Level-1 zombies will change over time, and their internal organs will rot more or less. The smell is like the stench produced by being buried in the soil and decomposed by bacteria.

But level two zombies are different.

Their internal organs will produce a similar stench, but the degree of decay is smaller than that of first-class zombies. Moreover, their hearts will beat, very small beat.

Of course, the rupture of the heart will not lead to the death of the second-class zombie, but it is no longer human, and the heart will beat. Isn't it a very strange thing?

Take out the last potion and drip it into the body of the zombie with a dropper. A burst of white smoke rises slowly.

But the stench is better than just now.

Eighteen took out the scalpel and continued to dissect. When he finished everything, the level II zombie with begging eyes was vicious. Looking at eighteen, he wanted to devour him alive.

Eighteen long and narrow Danfeng, with a cold light at the bottom of her eyes, lightly crossed the face of the second-class zombie and walked away.

The sole collided with the ground and made a dull sound. The final impression of the secondary zombie was darkness.

Throw the protective clothing stained with zombie blood into the garbage basket, go to the data analysis room, take out the blood of catkins, and then analyze it.

Looking at the data analysis results, eighteen blinked in surprise.

On the vessel, after contacting with the air, the blood of catkins quickly changed from black to beautiful blood red. Instead of losing the unique odor of blood, it exudes a smell of erosion, just like what he smelled in the supermarket that day. According to the data analysis, the similarity between catkins' blood and human blood is only 40%, The blood immune cells of catkins only have a small number of leukocytes, and most of them are strange phagocytes.

These phagocytes can devour everything, but they seem to work only when they encounter air.

Presumably, this kind of immune cells swallowed up the zombie virus, only because they did not touch the air and did not completely swallow it, but only inhibited the zombie virus. Because the virus injected into catkins was an extracted improved virus, there was a small part of variation.

and.

The blood of catkins seems to have produced antibodies. Give her another period of time, I'm afraid it will completely devour the virus he injected, and even produce immune antibodies.

Eighteen raised his hand and rubbed his forehead, which was tired because he didn't sleep all night. Sure enough, this catkins is worth studying.

It's just that she's not so lucky this time.

Eighteen, put the improved virus in your pocket and get ready to greet catkins.

Drive back to the base.

18. Turn on the monitoring of the room while starting the automatic driving mode.

But the bed where Jiu Jiu was lying was already empty. Eighteen eyelids jumped, and there was a bad feeling in his heart. He opened the monitoring and observed the house in all aspects, but he didn't see Jiu Jiu's figure.

There is no trace of clothes on the bedside table. There is water trace in the bathroom. It can be seen that Jiujiu has taken a bath. Enlarge the water trace, look at the water trace, and use the water steaming time to infer that Jiujiu has been away for more than six hours.

Based on this inference, it can be seen that Jiujiu went to take a bath after he turned off the monitoring.

Set the time when he turns off the monitoring.

Ten minutes after he turned off the monitor, Jiujiu got up from bed, took a bath, and finally climbed out of the window.

Looking at Jiujiu's back and the smile at the corner of her mouth when she finally turned back, it can be seen that she clearly had thought about everything for a long time, even calculated her time from the base to the laboratory, and even showed a sarcastic smile when she left. It can be seen that she knew she would call out the monitoring.

This woman.

She dared.

When she thought of her lovely and submissive appearance when she left, it was clear that she had already thought of leaving. Her cleverness, her submissiveness and her obedience were all because she wanted to leave herself. Eighteen felt a chill.

He didn't understand that he had given Jiujiu the best. Why did she leave herself? If it was because of what happened that night, he apologized, but why did she leave herself.

He really likes her very much. She quietly broke into her life and told herself that she is Jiujiu and her own woman. But now, she looks cold and even tries to leave him. It is clear that she is the one who does everything. Why is he the one who is hurt.

Eighteen drooped his eyes and sat quietly in the carriage. He didn't move for a long time. Even the experimental data that satisfied him didn't make his heart splash a little.

If he didn't promise Jiujiu to travel by time machine, wouldn't these things happen? Would she still be her own, won't forget herself, won't deceive herself, or even hurt herself like this.

His heart hurts.

After leaving the 18th apartment, Jiujiu directly stops a soldier and asks him to take him to Lin Li.

Hearing Jiujiu's request to see Lin Li, Xiaobing's ears moved, and his side eyes looked up and down at Jiujiu. After seeing Jiujiu's exquisite face, there was a touch of surprise at the bottom of his eyes, but the surprise was fleeting, and a moment later he was numb.

There are too many beautiful women, and their beautiful faces are all the same. Moreover, at the end of the moral collapse, when everything is missing, beautiful women are like a gem on clothes. Now people are running out of food. Where will anyone care about the gem on clothes.

And Lin Li is famous for his selflessness. From the establishment of the base to now, countless women have come to hook up with Lin Li, but none of them have really succeeded. Therefore, they agree with Jiujiu's eyebrow soldier, but despise her coming to Lin Li.

"The general is very busy. I'm afraid he doesn't have time..."

Before Xiaobing finished, Jiujiu directly said, "tell Lin Li, I know how to make zombie vaccine."

"What?" the soldier looked at Jiujiu in surprise and stared at the boss.

"I'm a scientist. I participated in the research of zombie vaccine before the end of the day. Please help me inform Lin Li." the research of zombie vaccine was really carried out before the end of the day. Lin Li also knew this, but he didn't know that the main person in charge of vaccine development at that time was Xu night.

Because it was urgent, Xiaobing immediately took Jiujiu to Lin Li's office.
