Guo Ying covered his face with unusual grievances, but he had a strange feeling in his heart, feeling that he couldn't disobey Zhang Xiaofan's order, so he said to the people behind him: "Have you heard it, guard here, and obey Zhang Xiaofan's orders." ”

"Yes, my goddess."

At this moment, the girls of the four groups all walked to the edge of the wall at the back and prepared to leave, Su Qianqian and Lin Rou were from the medical team, although they didn't want to leave, but under Zhang Xiaofan's unquestionable order, the two of them had to leave.

There were more than half of the people on the field at once, which was also a helpless move, because if you retreat in a hurry, there will be too many people, and at that time, I am afraid it will be too late to retreat.

Almost half of the fighters here now have nail guns, and the rest have seven or eight people with pistols, which Wang Hu has worked so hard to get, because of the limited number of bullets, so he was reluctant to use them at first, but seeing that there are more and more of these killers, it is not possible to use them.

"Comrades, nearly three hours have passed, and if we hold on for a few more hours, we will be able to get through this difficulty, so we can delay for a while, and we must not let these killers attack our positions, remember, behind us are our families, all doctors, and our girlfriends, our failure, is their death, we must not take a step back, understand?" Zhang Xiaofan shouted.

"Understood!" What is surprising is that Guo Ying was the first to respond, and she shouted indignantly: "Support Boss Xiaofan, Boss Xiaofan's order is my order, understand?" ”

"Yes!"

Zhang Xiaofan was quite satisfied with Guo Ying's reaction at the moment, he said: "Prepare, shoot!" ”

The people who had already loaded the nail guns fired one after another, while Wang Hu and Zhang Xiaofan took out their pistols and began to shoot.

"Bang bang, bang bang ......"

Gunshots rang out everywhere, and fires flew everywhere.

At this moment, it seems to be a realistic version of Plants vs. Zombies, Zhang Xiaofan They belong to plants, and the killer troops opposite are zombie groups, but fortunately, the killers are slow, so they can't attack for a while, but gradually, the number of killers is increasing.

Not far away, the group above the toilet finally couldn't hold on, and the killer troops actually let their companions climb on top of them and attack, and at first it was okay, these people were able to drive the killer down.

But then, as the numbers grew, the killers finally climbed up.

On the top of the toilet, a female killer smiled and said, "Good familiar classmates, hello everyone, I'm here again, let's send you to death, it's my greeting gift." ”

This girl was the first person in the class to die, and at this moment her resentful gaze scanned the audience and slashed the scythe out.

A boy held a machete to resist violently, but the texture of the machete was so bad that he was cut in half by the sickle at once, and then the sickle was castrated, instantly cutting the boy's neck!

"Poof......

"The boss is dead, the boss is dead......"

"Run, I don't want to die......"

The death of the leader instantly broke the small group, and the classmates jumped from the toilet in a panic, and then were hacked to death by the killer troops who had been waiting for a long time under the toilet.

In the end, only two or three classmates escaped from the small group with their injuries.

As the last fortification on the playground was breached, now only Zhang Xiaofan and them were left, Zhang Xiaofan sent out fireballs one after another, trying to resist the army of killers on the opposite side, but there were more and more killers, and soon the number exceeded thirty.

"Oh no, I ...... My nail gun got stuck. A boy fiddled with a nail gun and said in horror.

"Made, are there no new ones?" Wang Hu scolded.

"The new ones have long since run out."

Zhang Xiaofan's expression was unusually grim, he was still careless, the intensity of the battle this time exceeded his imagination, he didn't expect that there would be so many killers, and the nail guns prepared before were simply not enough.

Zhang Xiaofan threw out a few fireballs and shouted: "It's really not okay to hit it with stones!" ”

"Yes!"

As time passed, the killers inevitably got closer and closer, and Zhang Xiaofan finally gave the order to retreat to the second position.

At this moment, Song Feng and Shen Fengxing and these killers also got up, they all ate a lot of meat just now, and they were almost recovered, Shen Fengxing sneered and said: "Zhang Xiaofan, you caused me to die, I won't let you go." ”

"Chen Jing, Chen Jing, this girl killed me, I won't let her go." Song Feng shouted.

Finally, the army of killers attacked the second position, and Zhang Xiaofan ordered and shouted: "Retreat, enter the escape hole, and start the van!" ”

On the other side of the wall, several vans had already been parked here, but there were also many killers on the other side of the wall, and after seeing people suddenly emerging from the hole, they surrounded them.

"It's not going to go on like this, let's get them away first."

As the guardian of the medical team, Xu Shiyong immediately ordered his subordinates to drive the van to knock the army of killers who surrounded him out, and then looked back, he opened the door behind the van, and shouted arrogantly: "Turtle sons, you have the ability to chase your grandfather, hahaha......"

Although the killer is a high-tech robot, he has retained his past memories and sanity, and when he heard the provocation, he naturally rushed over.

"What are you to dare to provoke our killer robots."

"Yes, we sent death for you, if you are not grateful, forget it, and scold your mother, it is really hateful, since this is the case, we will destroy you!"

The killers rushed over one by one, and for a while there were no killers on this side of the wall, Su Qianqian and Lin Rou walked out one after another, and then opened the remaining car doors.

"Quick, get in the car." Su Qianqian organized the crowd and said.

The girls in the cave climbed out one by one, although they were frightened, but they also understood that this was a race against time, so they obediently got into the car one by one.

These vans have been modified, with iron windows welded to the outside of the cars, and a half-meter-long iron spear is placed inside to pierce the inside of the car, and the front of the van is also equipped with an iron spear tip for ramming.

Zhang Xiaofan's side is now fighting hard, and there are only about a dozen people left, and most of them have evacuated, even Guo Ying asked her to evacuate first.

Finally, the army of killers entered the second position, where the pit had already been dug and fell into it one by one due to their faltering steps.

"Good, it's all buried!"

Zhang Xiaofan gave an order, and several strong men threw down the mud woven bags that had been prepared long ago.

For a time, more than a dozen killers were buried alive underneath.
