Of course, in terms of Li Hu's current strength, this zombie is not enough.

Another kick kicks the zombie away. Li Hu takes Yang Ze's machete and rushes up to chop.

The zombie quickly became smaller with the speed visible to the naked eye, first with both hands, then with both legs, and finally with only one head kicked by Li Hu like a ball.

"Brother Yi, kill it." Li Hu stepped on the head of the zombie and panted.

His body has been a lot of injuries, chest has been blood red, deep visible bone.

It can be seen that even with Li Hu's current strength, it is difficult to kill this zombie.

"Old man, is your broken extract safe or not? After a while, I became a zombie. "

After a few breaths, Li Hu couldn't help saying.

This secondary evolutor will become a zombie immediately after using the extract. Is it possible that the effect will be much slower if they have a higher level?

As soon as he said this, Yang Ze's face became bitter.

Just now, he also used extract.

"Well, I don't know." Professor Cheng waved his hand.

"Damn, I'll become a zombie soon, and I'll kill you first!" Li Hu roared with staring eyes.

Professor Cheng can be scared enough, shivering away from these two people.

"No, he's a zombie, but you'll never be."

At this moment, Wang Yi suddenly came forward, opened the code box, and took out an extract from it.

"If my guess is right, the zombie virus in the extract has not been completely separated. The reason why Li Hu and Yang Ze are OK is that they are evolutors of level 3 or above. They have antibodies against zombie virus in their bodies for a long time. Therefore, they have not become zombies."

"And this man." Wang Yi said, pointing to the fragmented corpses on the ground.

"He was a secondary evolutor before, and there was no antibody against zombie virus in his body, so he was infected as a zombie."

"Damn it, old man Cheng, you said that the refining liquid has been finished!" Li Hu's anger flashed in his eyes. He turned his head and stared at Professor Cheng. A second-class soldier died directly because of the zombie virus. If he was put on the battlefield, it would be possible to kill ordinary zombies, not to say against mutant zombies.

"Well, it's... but that army dog is OK." Professor Cheng stammered.

"Yes, brother Yi, the military dog also used the extract, but it did not become a mutant animal?"

Li Hu said with a puzzled face.

"I don't know. Maybe..."

"Roar!"

As soon as Wang Yi finished speaking, he heard a deafening roar, and then a burst of gunfire came from the cage not far away.

"Go and have a look."

Wang Yi's face sank, and he ran to the front. When he got to the place, he saw a bloodstain in the cage with the military dog. The military dog was also covered with blood and was lying on the ground twitching. Outside the cage, there were several soldiers with zero one rifles.

"What happened?" Wang Yi asked.

"Newspaper... Report chief, just now we were playing with the tank here. Unexpectedly, it suddenly went crazy, and then hit the iron cage that closed it crazily."

The soldier shivered and pointed to the iron cage. Next to him, he had been knocked out of a convex mouth. You should know that the steel bar was close to the thickness of his arm, and it was directly hit by the military dog. We can see how terrible its power is.

"And then you shoot it with rifles?" Li Hu pointed to the army dog that was not dead in the cage,

Maybe I felt that there were so many people coming outside, and the head of the military dog turned fiercely. With such a great effort, it changed a lot. Its eyes were red, and its two teeth doubled.

"I remember." Just then, Professor Cheng patted his head and said.

"Yesterday, when I used it for experiment, I only injected a small amount of extract into it because I was worried that it was small and could not bear too much energy. Is this the reason why it has been infected until now?"

Wang Yi smell speech, thought for a moment, gently nodded.

Zombie virus infection, in different species, different physique, the time of infection is completely different.

Of course, as long as we don't reach the level of third level evolutionist, we can't avoid being infected if we are caught or bitten by zombies. It's just a matter of time.

"Well, old man, I don't think you can find the reason. Maybe you are cheating us." Li Hu hummed.

"How can I lie to you? I have separated all the zombie viruses in the extract. Who knows there will be?"

Professor Cheng said helplessly,

"The virus in zombie blood can't be completely isolated." Just then, Wang Yi said in a deep voice.

"Because zombie blood is a virus. Even if there is a drop of trivial zombie blood in the extract, zombie virus will appear."

"But I have already..." Professor Cheng was stunned.

Yes, how can he tell that the zombie virus has been extracted? "

Now is not the original world, with the microscope to see is not necessarily all, perhaps, those zombie blood anything there is zombie virus.

"There are still 48 refined liquid left, Yang Bing. You can leave 20 for use in the gathering place of Lianfeng mountain. Remember to let the right soldiers choose by themselves, don't force them." Wang Yi said,

After all, the refined liquid is no better than other things, and Wang Yi can't guarantee whether there will be any side effects in the future.

However, this is also Wang Yi's own worry. After all, both Han Wan'er and Zhang Fei have used the extract, and it's not a short time now, and there is no problem.

"I understand." Yang Bing nodded and ordered his men to take out 20 pieces of refined liquid from the password box.

These things can enable any three-level evolutor to upgrade his strength to a higher level in a few minutes, which is not unimportant.

"And there's another important thing about my coming." Wang Yi said.

"Important?" Yang Bing thought about these two words.

The most important thing of Lianfeng mountain gathering place is to guard against the attack of corpses in Hohhot, and the other is the refining liquid and military factory. Wang Yi has already mentioned it. What else is important?

"Now, it's March. In more than a month, the snow in the north will melt..."

Wang Yi said softly.

Since August last year, the doomsday broke out and Zombies were rampant. After a winter, the surviving human beings have finally settled down. However, we don't know how many of them were eaten by zombies and how many of them fell on the cold winter night.

But this winter will soon pass, and mankind will welcome the first spring after the end.

This season, even in his previous life, was also Wang Yi's favorite.

No summer heat, no winter cold, but can plant hope to live.

"Brother Yi, you mean..."

Yang Bing was stunned, and immediately responded, with a flash of light in his eyes.

"That's right. When I came back from the coal gathering place, I saved a professor who thought he was specialized in agriculture. He had the latest research results, which could be planted many times in a year." Wang Yi said.

"Brother Yi, when spring comes, shall we plant grain?" Yang Bing said.

"Yes, although there is a lot of grain in our gathering place now, which can support the food consumption of the gathering place for several months, once it is used up, we have to go to Hohhot or other surrounding cities to collect it. It is too dangerous, and it is not certain whether the collected grain can be eaten in a few months."

Wang Yi said solemnly.

After all, there should be a shelf life for grain, and it will be less and less, and it will be more and more difficult to collect. Instead of working hard for a little grain at that time, it is better to take the lead in planting grain when there is a chance, at least not to starve until the next winter.

"But where should we plant it?" Yang Bing looked bitter and asked.

Looking around, we can see that there are all zombies around the two gathering places. If we want to grow food for hundreds of thousands of people a year, the scale can't be small. But the zombies are not dead, and they may attack at any time. If we attack the two gathering places, we can resist for a while, but if we spoil the food growing places, There's no way but to watch.

"That's what I want to discuss with you." Wang Yi glanced around and said.

"Let's go to the conference room and say."

In the conference room, there were only Wang Yi and Yang Bing. Wang Yi didn't let other people in, but it wasn't a secret matter to discuss. The main thing was that the food related to the future development of the gathering place. Like Li Hu and Yang Ze, they didn't have any opinions, and it was useless to come in.

"Brother Yi, this is the map of the whole Mongolian province." Yang Bing laid a huge map on the table.

"If you look around us, there are some places suitable for large-scale grain cultivation." Wang Yi said.

After a long time, Yang Bing looked up in disappointment.

"No, in our neighborhood, the only area suitable for large-scale cultivation of food is the area between Daqingshan and Hohhot. Other places are either hilly areas or scattered counties and towns. If they are planted, the zombies will come out from time to time to harass them. We can't get rid of these counties and towns one by one, One is that we don't have such a large number of troops, and the other is that it's not worth the loss. "

Yang Bing said with a disappointed face.

"But this area is next to Hohhot. No one knows when the corpses in Hohhot will suddenly riot. If we plant food, we will be in vain if we are ruined by the corpses."
