At this moment, the zombies who had previously thrown stones across the Xin'an River had a new move.

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

At the beginning, the soldiers on the city wall could not understand the behavior of these zombies, but as more and more stones were thrown into the river, and after filling a place where they could step on the river, everyone finally understood what these zombies were doing.

These zombies are indeed unable to build bridges, but they can fill rivers and build roads!

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

With so many materials, let alone filling out one way, it is not a problem to fill out dozens of them.

Looking at the slowly piled up stones, these soldiers couldn't help but be anxious. There were more than 20,000 zombies with wisdom on the opposite side.

Even if each of these zombies carries a stone and throws it into the river, it will be dozens of tons in total.

At this speed, it may not take long before these zombies can fill out a path.

Looking at the incredible scene in front of him, Li Bei wanted to slap his mouth twice, and he would really come whatever he said.

Wu Hai and others beside him glared at him angrily. Although they knew that this was not Li Bei's fault, the crow's mouth was indeed annoying.

"Want it, fight me. First, kill these wise zombies. I can see how they can fill the river and build roads." Li Bei ordered loudly.

At the same time, he also snatched the automatic rifle from a guard beside him, and shot several zombies that 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, and then the soldiers of other regiments also fired guns and responded after seeing them.

For a moment, with the death of second-level zombies, the momentum of filling the river was temporarily curbed.

However, before everyone could breathe a sigh of relief, they saw the mutant zombies wandering around the river bank and began to roar.

As the roar of the mutant zombies, the ordinary zombies beside them seemed to go crazy at this time, rushed towards the river bank and mixed into the wise second-level zombie team to resist bullets for them.

At this time, the zombies' spirit of not fearing death was once again reflected. These zombies did not understand what fear or pain meant. Even if they were shot, as long as they did not die on the spot, they would desperately rush towards Xin'an River with the stone in their arms.

There were even many zombies who ran to the shore and were shot dead. They also hugged the stones tightly and fell into the river together. Their bodies would also become part of the river filling, which would speed up the river filling speed.

In just 5 minutes, the zombies on the opposite side filled up to 20 meters. If you follow this speed, wouldn’t you be able to fill up here in less than 25 minutes?

Even if the terrain in the center of the river is low and the river is turbulent, it should not exceed half an hour.

"Teacher, what should we do now?" Wu Hai was also a little stunned when he saw this scene. He asked Peng De beside him.

Such a situation was something they had never expected before.

After hearing Wu Hai's words, Peng De narrowed his eyes slightly. At this time, 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 out all the thoughts in his mind, and then turned his gaze again, the group of zombies who were still constantly filling rivers and building roads.

No matter what the future changes will be for the zombies, the most important thing now is to overcome this difficulty.

"How many howitzers are there?" 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 these twenty howitzers, ten were purchased by Sun Xue through a caravan from Shuangzhou City. Otherwise, they would have left even fewer of this heavy weapon of destruction.

"Then let the soldiers of the artillery battalion prepare. After the zombies fill up the road, they will directly knock it down from the middle." Peng De ordered.

After hearing Peng De say this, the team leader around him lit up his eyes. This was indeed a very good solution. It also made them feel a little relieved.

Bang bang bang bang!

Gunshots were ringing one after another, and the soldiers on the city wall were constantly aiming and shooting, killing second-level zombies holding stones.

When they find that the zombies in front are killed, they will fall down from Xin'an River with stones in their arms, and these soldiers will instead shoot the zombies in the rear. In this way, these zombies will never fall into Xin'an River.

After killing the zombies behind, they will not fall into the Xin'an River. However, when these zombies fall to the ground, the zombies beside them will lift the corpses, bring the stones on the ground, and throw them into the Xin'an River together.

And in this process, they were like corpses as shields, making it more difficult for soldiers to kill them.

Obviously, no matter whether you shoot the zombies in front or the zombies behind, you can't do a good job.

What they can do now is to shoot and kill these zombies as fast as possible. By then, without these zombies with wisdom, there would be no more corpse tides coming.

Bang bang bang bang!

Under the pressure of the crisis, these soldiers performed extraordinaryly. Zombies kept falling down, and were then lifted up by the zombies beside them and threw them into Xin'an River together.

The battle continues, almost every minute and every second, this road that was filled out can extend a lot.

It soon passed twenty minutes, and at this time, the road filled with zombies and huge rocks had extended to two-thirds of the Xin'an River.

"Tell me the order and let the artillery battalion take a shot in the middle of this road." At this time, Peng De finally gave an order.

"Yes!" After hearing this, the messenger beside him immediately entered a military salute and hurried away.

Less than thirty seconds after Peng De's order was issued, a grenade shot into the sky from the Xin'an base. After crossing a beautiful parabola, it accurately fell into the center of the road that had been filled with half.

boom!
