There should be a master tactician in this group of people, who has designed this ingenious method of attacking the prison camp, and even hid some traps inside, just waiting for Zhang Shengli to get into it by himself.

Zhang Hua came to the high wall with a few spears that he had made in his spare time these days, but after a few attempts, he gave up attacking the motorcyclists...... Because his ability can't lock onto a target that's moving at such a high speed.

After several motorcyclists on four-wheeled mountain bikes led the corpse tide to the vicinity of the prison, they immediately sped away, and the corpse tide, which had lost its target, remained near the prison gate, but only wandered aimlessly around the periphery, and did not mean to approach the prison wall.

Now the situation of Zhang Shengli and other team members in the prison is quite embarrassing, they are cooking on the fire, and at this time they all stopped under Zhang Shengli's order, staying in the prison and not daring to move, not daring to make any noise.

Because once the noise is made, it is likely to attract the attention of this wave of corpses, and according to the usual habit of these zombies, they will immediately come close to the sound and try to enter the prison, and they will even build a human ladder on the high wall outside the prison to achieve this purpose.

The attack ability of two thousand zombies should not be underestimated, and it is not difficult for them to build a human ladder to climb the eight-meter-high wall, and there are still many wounded in the prison now, in this case, whether it is defense or transfer, it will be a big problem.

Just as Zhang Shengli was highly vigilant observing the corpse tide around him, his mind was quickly thinking about how to deal with it. The direction of the back wall of the prison, the one that had not yet been occupied by the tide of corpses, was suddenly thrown in with a few firecrackers, and they were lit firecrackers.

The sound of these loud firecrackers immediately attracted the attention of all the zombies in the vicinity. They were originally following the motorcycle, after losing the attraction of the roar of the motorcycle. Just wandering around the prison unconsciously. At this moment, when they heard the sound of firecrackers, they rushed frantically towards the prison wall.

Although Zhang Shengli immediately arranged for someone to rush over to extinguish the firecrackers, more than 2,000 zombies had already surrounded the prison from near the big iron gate because of the sound of firecrackers, and after arriving at the edge of the high wall, they soon smelled the smell of fresh flesh and blood wafting from the high wall, which made them go crazy and try to climb the high wall to enter the prison.

Fortunately, the prison is big enough. Two thousand zombies were not enough to pile up a human ladder, and they quickly dispersed along the high wall, and the threat of dispersion and dilution was not very great. But because of the smell of fresh flesh and blood in the prison, they gathered around the high wall and screamed and refused to leave.

Occasionally, there are places where zombies are concentrated, and at most only two or three layers of human ladders have been erected, and then they have retreated and collapsed because of the weak foundation, which does not pose much threat to the prison for the time being.

But soon Zhang Shengli found that the situation was a little bad, just now the motorcyclists from the distant field did not make much noise and quietly returned to the place where they had brought the zombies before, about twenty minutes later, these motorcyclists went and returned, and attracted another wave of corpses, this time much more than the last time. About 4,000 or so came to the vicinity of the prison.

Zhang Shengli found a few gunmen and shot at the motorcyclists with scoped rifles and assault rifles. Unfortunately, they had large shields, they were extremely fast, and they were far away, and the gunners were not professionally trained, their accuracy was poor, and it was difficult for bullets to hit them, not even on their motorcycles.

Soon several mountain bikes accelerated to escape, zombies have a hobby of gathering, those zombies who were attracted by them again after losing the goal of the roaring motorcycle, found that there were a lot of screaming zombies gathered around the prison wall, so they subconsciously converged here.

After the rendezvous, these zombies also smelled the fresh smell of flesh and blood inside the high wall, and gathered together with the two thousand zombies that were originally gathered around the high wall, and began to build a new human ladder.

After more than 4,000 zombies were added, the total number reached more than 6,000, and the efficiency of the tower ladder was obviously much higher than before, and soon a place where zombies gathered more had a ladder that broke through the height of the high wall, and several zombies roared and climbed the high wall one after another, Zhang Shengli had to lead people to rush over, wielding a fire axe to slash these zombies on the spot.

The sound of the battle attracted the other zombies on the side of the nearby high wall, they set up a human ladder even more frantically, more zombies climbed the high wall, Zhang Shengli and others could barely hold the high wall here, he had to throw a grenade down, exploded at the foundation of the human ladder, and finally solved this wave of zombie fierce attacks after a burst of flesh and blood.

In order to prevent the zombies from gathering too much outside the high wall somewhere, Zhang Shengli had to arrange all the people who could be used on the high wall, and according to the distribution of the zombies outside, let the guards standing on the high wall in different positions shout loudly to attract the attention of these zombies, not to let them gather too much, and not to let the ladder pile up too high.

At the same time, Zhang Shengli also asked the women to make some Molotov cocktails out of gasoline and empty beer bottles in the warehouse, replacing the small number of grenades to carry out burning attacks on places where zombies are concentrated. However, the storage of glass bottles in the prison is limited, and one of the team members was smart and directly poured gasoline on the high wall with a lunch box, and as a result, he accidentally burned himself into a burning man, and the person who went to help was also burned and had to retreat, watching the team member scream and fall to the ground with severe burns.

Zhang Shengli hurriedly stopped the team's gasoline attack, gasoline is a very dangerous thing, after there are many fire points outside the prison, playing with gasoline like this is likely not to burn the zombies outside, but to burn his own people alive in the prison.

As the attention of the zombies outside the high wall was attracted by the players on the high wall, they all desperately crowded near the high wall, and there were more and more places to set up human ladders, which made Zhang Shengli feel like he couldn't guard against it.

Soon, another human ladder broke through the defense of the high wall, and several zombies roared and climbed the wall, and Zhang Shengli had no choice but to throw out a grenade to blow up the human ladder.

In the apocalypse, even if a place like a prison is strong, it is not a good idea to be trapped inside, and it may be easier to deal with mindless zombies, but it is not so easy to deal with players and survivors who covet this place, and they will come up with all kinds of perverted ~ siege methods to torture and kill the people trapped inside.
