Rather than being shot to death by fire guards and drawn artillery, it is better to use it to fill pits to facilitate the progress of the infected group behind, which is also a bit of contribution.

As the infected group moved forward regardless of loss, some five-meter-deep pits were quickly filled up, and the pits were full of infected bodies.

After being stepped on by the infected body group behind, most of the infected body in the pit was trampled to death and turned into meat sauce.

Even if there are no dead, they can only be buried underneath and cannot move. It is estimated that there will be no chance to come up in this life...

Two minutes later, the infected group had advanced hundreds of meters, which also meant that they had filled the 100-meter pit.

To know that there are 20 large pits in this distance, the slave laborers and the digging sandworms dug for nearly a day, and they were filled in only two minutes, which is enough to explain the horror of the infected group.

Of course, the price they paid was also huge. Nearly 300,000 infected bodies were buried under these pits forever, causing the first echelon of the infected body group to drop sharply by a quarter.

In addition to those infected bodies that were killed by fire guards and drawn artillery before, there are currently less than one million ordinary infected bodies left in the first echelon.

At this time, it was less than half an hour before the battle started, which was enough to show the intensity and cruelty of the battle.

Although the results of the battle were impressive, the people on the road side were not happy, and all of them looked solemn.

Because they also consumed two sets of ammunition in the past few minutes, now there are not many ammunition left, and it is difficult to continue the battle.

The most important thing is that there is still no sign of the spiritual barrier in front of it being broken. If this continues, even if their ammunition is exhausted, the infected group will advance sooner or later.

"Don't panic, don't panic, we have dug enough pits, these millions of infected bodies are not enough to fill, then they may be able to bury their second-tier mutant infected bodies, so that the pressure behind us will be Much smaller..." Anan's voice was trembling, not sure if he was comforting everyone or comforting himself.

But as soon as Anan finished speaking, Xiaowan’s voice came from the short-range communicator: “No! There are new actions in the infected group! The fourth echelon of ordinary infected bodies are coming up, and there are a lot of them. Two million or so, it is estimated that they came up to fill the hole!"

This warning made everyone's expressions change. Originally, their thoughts were similar to those of Anan, and they felt that they could use the big hole to limit the infected body group.

But now it seems that the corpse controller also thought of this, and made precautions in advance, making them a little caught off guard.

"Boss Lu, we can no longer consume ammunition. Otherwise, waiting for these pits to be filled, there will be no hindrance to the mutant infected bodies behind. We must reserve some ammunition for defense!" The butcher suddenly stood beside the Lu Army and made suggestions.

"No, the firepower cannot be stopped, otherwise everything I did before will fall short, and the rear will continue to increase the firepower for me!" The Lu Army directly rejected the butcher's suggestion.

"But..." The butcher wanted to say something to the Lu Army.

"Needless to say, I know your thoughts and concerns, but I have a hunch that the corpse controller will soon be unable to hold it. The spiritual barrier will be broken within ten seconds, and we will hold it for another ten seconds." Lu Jun Raised his right hand, otherwise the butcher continued to speak, and then stared at the mental barrier above.

A few seconds later, the fire guards and the plucked artillery at the rear could be seen attacking a lot more fiercely. It is estimated that the members of the resistance army passed the order of the road army.

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

It is estimated that the corpse controllers can also feel that the situation is urgent, and immediately strengthened their mental output, allowing the mental barrier to gradually return to normal.

It can be clearly seen that the mental barrier at this time is like a balloon that is about to shrink, and it immediately fills up again and becomes full.

While one side is fully attacking and the other side is fully defending, the result is a stalemate.

"Boss Lu, this..." The butcher's expression was a little ugly, he pointed his finger at the spiritual barrier in the distance, and he stopped talking.

"Keep on attacking, the corpse controller is holding on. It won't last long, don't stop!" The Lu Army said directly in the short-range communicator. This was to the resistance army members and Xiaowan who were in charge of the defense facilities.

"Understand, we will continue to maintain the maximum firepower output!" Rebel members replied.

"Understand, we will continue to attack!" Xiao Wan also returned her voice.

Immediately after, she let all the flying mutant beast abilities be fully activated, attacking the spiritual barrier at any cost.

Although there are no flying infected beasts here, they have long-range attacks.

In the next moment, some of the rippers and lickers in the third echelon stepped forward with the help of the elite infected body, and attacked the flying creatures on Xiaowan's side with the extreme distance.

When a thick sour bomb and thick tongues ejected from the mouths of the rippers and lickers, half of the sky was filled.

If it is normal, this kind of attacking flying creature can completely avoid it, and even fly over to kill the rippers and lickers.

But now there is a mental barrier to block it, which means that the infected body can hit the flying creature, but the flying creature can't hit the infected body.

In addition, the flying creatures were busy attacking the mental barrier, and the positions were relatively dense, and they couldn't disperse at once, were beaten upright, and immediately suffered a lot of casualties.

Fortunately, the Lu Army's spiked dinosaurs attacked a long distance, staying behind, did not let the infected body attack.

Xiaowan also promptly told the flying creatures to withdraw back, opening the distance from the spiritual barrier.

In this way, the rippers and the lickers can only stand in place and watch them. Their attack distance is so far that they can't squeeze it further. After all, there are more than one million ordinary infected bodies in front of them.

In this way, after a brief encounter, the two sides fell into a stalemate again.

During the period, the firepower on the road side continued, and various ammunition was rapidly consumed. The infected people use the spiritual barrier to forcefully advance against the firepower of the road army.

In the absence of casualties, the infected body was advancing quickly and immediately reached the traps arranged by the slave laborers, that is, the big pits.

These ordinary infected bodies with no brains didn't even look at the ground. They walked directly into the big pit, fell off with a sound of "Hawk", and couldn't climb up again.

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

The corpse controller knows that there is a pit in front, and can also control the infected body not to jump down. But they didn't do that, and they didn't even control it.

Because these ordinary infected bodies were originally cannon fodder, in short, they were sent to death.
