Because these common infectious agents are cannon fodder, in short, they are sent to death.

Instead of being killed by fire guards and pulling guns, it's better to use it to fill the pit and facilitate the infected population to move forward.

In spite of the loss of the infected body group, some five meter deep pits were quickly filled up, full of infected body bodies.

With being trampled by the infection group behind, most of the infection bodies in the pit were trampled to death and turned into meat sauce.

Even if some of them are not dead, they can only be buried below and can't move. It's estimated that they won't have a chance to come up in their lifetime

Two minutes later, the infected population moved a hundred meters further, which means that they filled the 100 meter hole.

You know, there are at least 20 big pits in this distance. Slave workers and ground diggers dug for nearly a day and filled them in just two minutes, which is enough to show the horror of the infected population.

Of course, they also pay a huge price, nearly 300000 infected bodies are permanently buried under these pits, resulting in a sharp reduction of the first echelon of infected body population by a quarter.

In addition to the infected bodies killed by fire guards and artillery, the number of ordinary infected bodies left in the first echelon is less than one million.

At this time, it is less than half an hour from the beginning of the battle, which is enough to show the intensity and cruelty of the battle.

Although the results of the war were brilliant, the people on the side of the road army were not happy. They were all dignified.

Because they have consumed two groups of ammunition in the past few minutes, there is not much ammunition left now, so it is difficult to continue the fight in the future.

The most important thing is that there is still no sign of the mental barrier breaking in front of them. If they continue to do so, their ammunition will be consumed, and sooner or later the infected population will push forward.

"Don't panic, don't panic at all. We've dug enough holes, and there are not enough infected bodies to fill. By then, we may be able to bury the second echelon of mutated infected bodies, so that the pressure behind us will be much less..." Anan's voice with some tremors, I don't know whether to comfort the people or to comfort myself.

But just as Anan finished the sentence, Xiaowan's voice came from the short-range communicator: "no! There's something new in the infection group! The fourth echelon of common infectious agents are surging up, the number is about two million, it is estimated that they are coming up to cooperate with the pit filling! "

This early warning changed people's faces. Originally, their idea was similar to Anan's, and they thought that they could use the big pit to limit the infected population.

But now it seems that the corpse control also thought of this, and made prevention in advance, so that they were caught off guard.

"Boss Lu, we can't consume ammunition any more. Otherwise, when these pits are filled, there will be no obstacles for those mutated infectious bodies behind. We must reserve some ammunition for defense!" The butcher suddenly stood by the soldiers and offered his advice.

"No, the firepower can't be stopped, otherwise everything done in front will fall short, and the rear will continue to increase the firepower for me!" The army directly rejected the butcher's proposal.

"But..." What else does the butcher want to say to the army.

"Needless to say, I know what you think and what you worry about." The passer-by raised his right hand, otherwise the butcher would go on and stare at the opening of the spiritual barrier above. "But I have a hunch that the corpse controller will be unable to hold on soon. The mental barrier will be broken in ten seconds. Let's hold on for another ten seconds!"

A few seconds later, we could see that the rear firepower guard and the artillery attack increased a lot. It is estimated that the rebel members passed on the order of the road army.

In this case, the mental barrier began to collapse at the speed visible to the naked eye, and it was about to crack completely.

It is estimated that the corpse controllers can also feel the emergency, and immediately strengthen the mental output, so that the mental barrier gradually returns to normal.

It is obvious that the spiritual barrier at this time is just like a balloon about to shrink. It is immediately full of air bombs and becomes full.

One side is attacking and the other side is defending. The result is a stalemate.

"Boss Lu, this..." The butcher's face was a little ugly. He pointed to the spiritual barrier in the distance and wanted to say nothing.

"Continue to attack, the corpse controller is supporting hard, can't hold for long, don't stop!" The soldiers said it directly in the short-range communicator. This was a conversation with the rebel members in charge of defense facilities and Xiao Wan.

"Understand, we will continue to maintain maximum output firepower!" Members of the resistance responded.

"Understand, we will continue to attack!" Xiaowan also sent back a voice.

Then she let all the flying mutant beast powers open, at any cost to attack the mental barrier.

Although there are no flying infected animals on this side of the infected population, they have long-range attacks.

At the next moment, some of the splitters and lickers in the third echelon stepped forward with the help of the elite infectious agent and attacked the flying creatures on Xiaowan's side with the limit distance.

Half the sky was filled as acid bombs and thick tongues shot out of the mouths of the gapers and lickers.

If it's normal, this attacking flying creature can completely escape, and even fly to kill the gaper and licker.But now there is a mental barrier, which belongs to the state that the infected body can hit the flying creature, and the flying creature can't hit the infected body.

In addition, the flying creatures were busy attacking the mental barrier. They stood in a dense position and couldn't be separated all of a sudden. They were hit in the right direction, causing a lot of casualties.

Fortunately, the sentinel dinosaurs of the road army had a long distance to attack. They stayed behind and didn't let the infected body attack them.

Xiaowan also asked the flying creatures to withdraw in time, which opened the distance from the spiritual barrier.

In this way, the splitters and lickers can only stand and watch. Their attack distance is so far that they can't push forward. After all, there are more than one million common infectious agents in front of them.

In this way, after a short fight, the two sides fell into a stalemate.

During this period, the firepower of the road army was constant, and all kinds of ammunition were rapidly consumed. Infected people are strong with the help of mental barrier against the fire of the road army.

In the case of no casualties, the infected body advanced very fast, and immediately arrived at the traps set by the slave workers, that is, the big pits.

These ordinary infected bodies with no brain do not look at the ground, but directly enter the pit, "Baji" fell down, and can no longer climb up.

The infected bodies behind are the same, falling into the pit one after another, and hundreds of infected bodies jump in every second.

The corpse controller knows that there is a pit in front of him, and he can control the infection. Don't jump. But they didn't do it. They didn't even care.
