At this time, the zombies on the other side of the Xin'an River who had thrown stones before had a new action at this moment.

I saw that what they picked up on the ground was no longer those small stones, but large stones or other heavy objects, picked them up, and then threw them into the Xin'an River.

At first, the soldiers on the city wall could not understand the behavior of the zombies, but as more and more stones were thrown into the river, and a place to step on the surface of the river was filled, everyone finally understood what the zombies were doing.

These zombies can't build bridges, but they can fill rivers and build roads!

If it was before, these zombies in the suburbs would definitely not be able to find so many stones to fill the river, but the problem is that in order to stop the zombies just now, they blew up more than half of the houses in the suburbs, and these bricks and stones are ready-made materials.

With so many materials, let alone filling in one road, even if you fill in dozens of them, it is not a problem.

Looking at the stones that were slowly being piled up, these soldiers couldn't help but be anxious, there were more than 20,000 of these intelligent zombies on the other side.

Even if each of these zombies held a stone and threw it into the river, it would add up to dozens of tons.

At this rate, I'm afraid it won't be long before this group of zombies can fill in a path.

Looking at this incredible scene in front of him, Li Beidu wanted to slap his mouth twice, which was really what he said.

And Wu Hai and the others beside him glared at him angrily, although they knew that it was not Li Bei's fault, but this crow's mouth was indeed infuriating.

"Fight, give me all the fights, first kill these wise zombies for me, and I'll see how they fill the river and build roads." Li Beida ordered loudly.

At the same time, he snatched the automatic rifle from the hand of one of the guards next to him, and with a few shots, he killed several zombies who were about to throw stones into the river.

Hearing Li Bei's order, the soldiers of the fifth regiment under him took the lead in action, followed by the soldiers of the other regiments, and after seeing it, they also shot in response.

Suddenly, with the death of second-order zombies, the momentum of this river reclamation was temporarily contained.

But before everyone could breathe a sigh of relief, they saw the mutated zombies wandering around the riverbank, and began to roar angrily.

And with the roar of those mutated zombies, the ordinary zombies beside them, like crazy, rushed towards the river bank at this time, blending into the team of intelligent second-order zombies, and resisting bullets for them.

At this time, the spirit of the zombies who are not afraid of death is once again reflected, and these zombies don't know what fear is and what pain is. Even if they were shot, as long as they didn't die on the spot, they would desperately hold the stones and rush to the Xin'an River.

There were even a lot of zombies who ran to the shore and were killed, and they also hugged the stones and fell into the river together. And their corpses will also become part of this river reclamation, which will speed up the degree of river reclamation.

In just 5 minutes, the zombies on the opposite side were filled with 2o meters, if it was according to this degree, wouldn't it take 25 minutes to fill this side?

Even if the center of the river is low and the river is fast, it shouldn't take more than half an hour.

"Commander, what should we do now?" Seeing this scene, Wu Hai was also a little dumbfounded, and he asked Peng De beside him.

Such a situation was something they had not expected before.

After hearing Wu Hai's words, Peng De's eyes narrowed slightly, and then he remembered that Ye Feng had said before that the evolution of zombies would become more and more terrifying, could it be that the current situation is a change that will occur after the evolution of zombies?

Peng De shook his head, threw all these thoughts out of his mind, and then moved his gaze back to the group of zombies who were still filling in the river and building roads.

No matter what happens to the zombies in the future, the most important thing now is to get through this difficult time.

"How many howitzers are there on our side?" Peng De suddenly asked.

Hearing Peng De's inquiry, the guards on the side immediately replied: "Report to the division commander, we still have twenty howitzers." ”

Among the twenty howitzers, ten of them were purchased by Sun Xue through the caravan that came from Shuangzhou City, otherwise they would have even fewer of these heavy weapons of destruction.

"Then let the soldiers of the artillery battalion prepare, and when the zombies fill up most of the road, they will directly bombard it in the middle for me." Pender opened his mouth and ordered.

Hearing Peng De say this, the eyes of the regiment leaders around him lit up, this is indeed a very good way. It also made them feel a little relieved in their hearts.

Bang bang bang!

Gunshots rang out one after another, and the soldiers on the city wall were constantly aiming and shooting, killing second-order zombies who were holding up stones one after another.

When the zombies in front of them are killed, they will also fall down the Xin'an River with the stones, and these soldiers will shoot the zombies in the rear instead, so that these zombies will never be able to fall into the Xin'an River.

After killing these zombies in the back instead, they really won't fall into the Xin'an River. It's just that when these zombies fall to the ground, the zombies next to them will lift these corpses, take the stones on the ground, and throw them into the Xin'an River.

And in the process, they have the corpse as a shield, making it more difficult for the soldier to kill them.

Obviously, whether you shoot the zombies in front or the zombies in the back, you can't have a good effect.

All they can do now is to shoot this group of zombies as fast as they can. At that time, without these intelligent zombies to stir up the situation, no matter how many corpse tides there are, they will not be able to come over.

Bang bang bang!

Under the pressure of the crisis, these soldiers often waved, and one by one the zombies kept falling, and then they were picked up by the zombies next to them and thrown into the Xin'an River together.

The battle continues, and almost every minute and every second, this road that has been filled in can extend a lot.

Twenty minutes passed quickly, and by this time, the road filled in by zombie corpses and boulders had extended to two-thirds of the Xin'an River.

"Pass my order and let the artillery battalion give a shot to the middle of this road." At this time, Peng De finally opened his mouth and gave the order.

"Yes!" When the herald beside him heard this, he immediately gave a military salute and hurried away.

Less than thirty seconds after Peng De's order was given, a grenade shot into the sky from the base in Xin'an City, and after crossing a graceful parabola, it fell accurately into the middle of the half-filled road.

Rumble!

Then came a deafening sound.
