After boosting morale, there was another problem in front of Wu Yu, that is, how to get in touch with the people in the other two buildings. The buildings are not very far apart, but only a few tens of meters, but the campus is full of zombies at the moment, and it is not easy for people to walk through them.

"Huzi, you don't pay attention to the training of sign language in your troops, it's the kind of gesture used to make simple communication when the special forces are fighting."

Listening to Wu Yu's question, Huzi smiled embarrassedly. Then he said: "We are just ordinary armed police, not special police, so we don't need that kind of sign language." ”

"It would be nice if there was a navy on the other side, and if you put a flag, the other party would understand what we meant." Wang Wei used to serve in the special forces, and not only knew the sign language for the special forces, but also knew some about the flag language of the navy. But in the face of ordinary armed police who don't need any codes, they really can't think of a good way to communicate over a long distance.

"If it really doesn't work, we have to send someone over directly." Wu Yu thought for a moment, "The largest distance between these buildings is no more than two hundred meters, and if you sprint with all your might, you can rush through it in dozens of seconds." I think we can try. ”

"I'll leave this task to me." Wang Wei took the initiative to ask, "This time I promise to complete the task." ”

"Without further ado, you can prepare your weapons and ammunition now." Wu Yu agreed to Wang Wei's invitation to fight, in fact, among the dozen or so people in this experimental building, except for Wu Yu, there is only Wang Wei who has this ability and courage. Although it looks safe downstairs at the moment, there are many unknown factors after all. Wu Yu couldn't leave easily, so he had to hand over this difficult task to this veteran.

"Rourou, go and gather all the food you find in those combat vests, and everyone will act when they are full." Wu Yu thought to himself that the soldiers and horses had not moved the grain and grass first, and everyone was probably hungry after a busy morning. After eating this full meal, he has the strength to act, especially Wang Wei has to do a 100-meter sprint to avoid the attack of zombies, and he has to eat and drink enough.

After a while, everything to eat was gathered. The most is compressed biscuits, which everyone thinks is too hard to eat, so they put it aside and keep it as dry food. Fortunately, the individual food of the field troops is not as monotonous as before, and there are many canned and self-heating foods in addition to compressed biscuits. Everyone opened the canned food and put the sauced beef and dehydrated vegetables into the stainless steel basin that was washed and used for physical experiments, added water, and then set up the basin, and put several alcohol lamps under it to heat it together.

Smelling the aroma of the broth in the basin makes people feel appetizing, and the water has not stopped because the power is out now, otherwise you will have to eat it dry, and the taste will be greatly reduced. Seeing that the soup in the pot was already hot, everyone tore open the self-heating rice packaging bag and poured water into it, and soon the hot rice was ready.

"It's been a long time since I've eaten field food in the army, but I didn't expect to eat it again here today." Wang Wei has a lot of affection for the life of the army back then, and now eating these individual soldier rations, he can't help but think of the days when he was a soldier again. Most of the others were eating it for the first time, and they all felt it was fresh, so they all munched on it.

"Bearded, there are these good things in the army, and your cooking class will be free." Qinghua asked, just now everyone knew that Hu Youcai was originally a cooking soldier, and they all liked to joke with him about this.

"This is eaten during exercises, and I usually eat this every day, so how much does it cost." Hu Youcai said while eating, don't look at him as a cooking soldier, he is not picky about eating. This simple quick food seemed to suit his appetite.

"When I was looking for these stainless steel basins for cooking just now, I found a lot of good things." Rourou smiled mysteriously after speaking, as if she had a lot of secrets.

"If you want to talk about it, hurry up, and you won't have time to talk when you're done eating." Wu Yu knew that she couldn't be too obedient to deal with this little girl, otherwise she would have to ask you to beg her, and she would have to beg her well before she was willing to tell the secret.

"I noticed that in the basement where these basins were kept, there were a lot of bottles and jars left over from the old chemistry lab. There's a lot of work in there. ”

"We don't have time to do experiments now, what's the use, can you say it quickly?" Qingyu was also intrigued by Rourou's pretended mystery.

"Those bottles and jars are full of chemical raw materials that can be used to make explosives with a little addition. When the time comes, we will have explosives, but we won't have to be afraid of zombies. A few explosive packets were thrown down, and all the zombies were blown up into the sky. You say I'm not a great idea. The more she talked, the more excited she became, she didn't even bother to eat, she stood up and talked as she walked, constantly describing to everyone the bright prospects she had in mind.

"Didn't you say it all yourself, something is missing?" Wu Yu didn't have much interest in Rourou's whimsy, "You have to know that ** is very unstable. If it blew itself up during manufacturing, it would be much better than letting a zombie bite to death. ”

"You know, I was a top student in the Department of Applied Chemistry when I was in college, and this is just a small thing for me, and it couldn't be easier." Rourou was confident in herself, "It's a pity that it's still a little bit of something, otherwise I'll let you see what I'm capable of." ”

"We can't make bombs, but we can make some Molotov cocktails." Wang Wei was inspired by Rourou and also came up with an idea. "There's diesel fuel in this building for backup generators, and these empty bottles, let's make some Molotov cocktails. You'll be able to save a lot of bullets then. ”

"Alright, let's talk it over." Wu Yu didn't have much confidence in this kind of homemade weapon, so he didn't want to invest too much energy, but was busy observing the movements of zombies on campus.

Everyone else finished their meals and went about their business. After Wang Wei talked to Rourou, he came over to discuss the safest route with Wu Yu, and it was time to prepare to go. Wang Wei hugged Xiaowen, Xiaowen couldn't help crying, and Tongtong sobbed quietly when she saw her mother crying. This made the atmosphere in the whole hall sad, after all, the danger factor of this task was still too high.

"There's a way, I've found a way." Originally, the sad atmosphere in the hall was brewing well, and everyone was ready to cry. But this atmosphere was interrupted by Rourou, and everyone turned their heads to look, but their eyes lit up. This time, Rourou is not bragging, she really found a good way.

I saw that Rourou was holding a homemade Molotov cocktail in her left hand, but in her right hand were a few walkie-talkies brought out by Wu Yu from the factory. At this time, it has only been two days since the zombie outbreak, and the walkie-talkie is basically useless for this time, and the electricity in it must be enough to make a long call.

"This is a charcoal in the snow, Wang Wei, after you bring this over, briefly explain the situation, open it, and then we can have normal contact with that side." Although there is a walkie-talkie, it still needs to be sent over, but this makes the significance of Wang Wei's action even more significant.

After that, a few people who followed Rourou to make Molotov cocktails also took the made Molotov cocktails to the hall, and everyone knew that the time for action had come, and they didn't say anything more.

Qinghua led a few people to open the door, Wang Wei put on all the weapons and equipment that could be used, and rushed out with a few Molotov cocktails. Under the cover of Hu Youcai and Huzi's firepower, Wang Wei smoothly rushed downstairs. During this time, the zombies who rushed to the front were knocked down by the bullets fired by the two coverers. If it was a horde of zombies, Wang Wei threw the Molotov cocktail over.

I have to say that the power of this self-made weapon is still very great, and it can be used to fight tanks in World War II before, and it is natural to deal with these unprotected zombies at this time. As long as the Molotov cocktail hits the ground and shatters, the liquid flowing out of it will ignite all the zombies around it. I saw these zombies howling in pain. But there was no way to extinguish the flames on his body.

Wang Wei didn't dare to fight, so he threw it away and ran away. There are not many Molotov cocktails on his body, after all, and they will be thrown away in a short time. At this time, in the face of the zombies that pounced on him, he didn't have time to raise his gun and shoot. I just hope to take advantage of the speed advantage and run to the school building where the lieutenant and them are staying before the zombies surround them.

Wu Yu did not stay in the hall on the first floor like the others, but took Qingyu to the rooftop of the top floor.

"You take the binoculars to help me observe the environment, and I'll cover your cousin." After Wu Yu handed the telescope to Qingyu, he set the gun on the fence of the rooftop and aimed it.

At first, Kureha didn't shoot, because the two people downstairs were enough to provide cover. But as Wang Wei ran away, there was not enough vision downstairs to shoot zombies. In order to avoid accidentally injuring Wang Wei, they had to close the door of the building and wait after knocking down the zombies that pounced on them around them.

At this time, Wu Yu began to shoot, although it was not a sniper rifle in his hand, but just an ordinary bayone bar. But at such a close distance, it is not a problem to fight a few zombies. The specific path has been discussed with Wang Wei before, as long as there are no accidents during the period, Wang Wei will not run too far away, and Wu Yu does not have to worry about accidentally injuring Wang Wei.

Soon Wang Wei approached the teaching building, and at this time, the guns in the teaching building also rang out.
