The young man who rushed towards the outside of the city was of course Ye Feng. At this time, he had already rushed into the dense tide of corpses and began to fight.

If an ordinary evolver dares to do this, he will definitely die miserably, and even rush in, he may not be able to get out.

However, at this time, Ye Feng was rushing around inside, and countless zombies rushed from all directions, but they couldn't even touch Ye Feng's sleeves.

Even Ye Feng's attention at this time was not focused on the zombies attacking around him, but released his mental power and began to investigate the surroundings.

"Not?" Ye Feng frowned slightly.

With his fourth-level mental power, he could immediately understand what was within four or five hundred meters with just a little investigation.

However, within this range, there was not even a fourth-level mutant zombie, and the commanders of the corpse groups were just ordinary zombies who were promoted to the fourth-level.

After Ye Feng's eyes swept, two three-inch-long flying knives appeared in his hand. After injecting his true energy, he swished twice and flew in both directions.

These two flying knives seemed to have spirituality, heading in two different directions, bypassing one zombies, and finally accurately hit two female zombies with slightly raised belly.

These two are both fourth-level zombies, and when the zombies reach the fourth level, their strength will have a qualitative leap. The most direct manifestation is that their skin will produce a stratum corneum. After having this stratum corneum, the skin of these zombies will be enhanced.

Basically, after the zombies reach the fourth level, ordinary pistols no longer have any threat to them, and even their skin defense cannot be broken.

Even automatic rifles that are several times more powerful will greatly reduce the damage they cause. Even if they hit the head, it will take at least two to three shots to kill a zombie.

It is precisely because of these reasons that the threat level of zombies will increase exponentially after they reach the fourth level. Of course, this is not the reason why Ye Feng took action and killed the two zombies. After the zombies reach the fourth level, there is another more important change, that is, their bodies have almost merged with the zombie virus.

The most direct result of this is that their physical functions have basically been improved, which also includes fertility.

Ye Feng just hunted two pregnant zombies. As long as they were given enough food, they could give birth to a small zombie in just ten days. This second-generation small zombie was basically not a human form when born. More than 90% of them were directly in the form of mutated zombies, while the second-generation mutated zombies will exceed the first generation of mutated zombies in all aspects.

It can be said that every second-generation mutated zombie is a huge threat to humans. It is also because of these reasons that Ye Feng is willing to spend some time solving them.

After dealing with the two female zombies, Ye Feng was no longer entangled with the surrounding zombies. He stepped on the ground with his right leg and rose up, stepping directly on the heads of these zombies and heading towards the city.

For others, the group of corpses that cannot be moved by inch are like walking on the ground, with the assistance of mental power. Ye Feng was able to accurately step on the heads of these zombies in mid-air, and within one step, they could fly more than ten meters, and soon they broke away from the range of the group of corpses.

......

Although Ye Feng's entry into the city also caused some trouble at the Yunqing City base, it was quickly calmed down under the closure order of Haidong.

And in these last two days, everyone devoted 200% of their energy to the construction of the city wall.

However, even though these people have worked very hard, the city wall cannot be built overnight, especially as it gets later, it becomes more difficult. It is not easy to just send materials to the eight-meter-high city wall.

Therefore, the height of the city wall eventually stays at the level of ten meters.

Of course, if you do your best, you should be able to build eleven meters, but since you have to leave some time to install city defense equipment, you will eventually stay at this height.

However, such a height is completely enough, because according to the calculations of the General Staff of the Alliance, only a five-meter-high city wall is needed to help them overcome this crisis. Now the ten-meter-high city wall is enough to make the soldiers of the Alliance feel at ease.

Soon, time came to the last day, and even ordinary soldiers felt like they were about to come.

As long as you stand on the city wall, you can find that these zombies have gathered to an extremely amazing level. Moreover, they are no longer far away, but are constantly approaching with time. Now they are less than ten kilometers away from their base.

At this time, the sun was hanging high, and these zombies were still slow and seemed a little lazy. However, everyone had a consensus that as soon as the night came, these zombies would become crazy, and by that time, it would probably be the time to formally siege the city.

Xu Youcai stood on the city wall, looked at the pointer on his arm, and pointed to the three days in the afternoon. At this time, the sun had already begun to set a little west, and there were only three hours left before the mountain went down.

Deng Yuxin stood beside Xu Youcai, looking at the dense zombies in the distance with a look of fear. Before, she was just an ordinary person, so every time there was a tide of corpse outbreak, she could only hide in the room and pray.

In short, this was the first time she had intuitively felt the horror of the corpse tide, so she couldn't help but hold Xu Youcai's arm tightly.

"Don't be afraid!" Seeing Deng Yuxin's reaction, Xu Youcai reached out and gently hugged the other person's waist.

When Xu Youcai hugged her, Deng Yuxin's body suddenly stiffened, and a blush appeared on her face, but she did not struggle.

Perhaps after experiencing the incident in Jinzhou City, the relationship between Xu Youcai and Deng Yuxin has gradually heated up over the past few days, and the relationship between the two has suddenly developed into a similar couple.

Perhaps because the atmosphere was a bit awkward, Xu Youcai coughed lightly and said, "What are these corpse tides? When the boss comes back, he can easily settle the problem by twice the amount."

Xu Youcai's words made Yi Yalan, who was standing in the distance, sigh leisurely, "I just don't know when he will come back."

Yiyalan said, looking towards the city, with a hint of worry.

Although everyone knows that Ye Feng is very powerful, even if he can go to the city alone, he is still worried. After all, no one can guarantee that there will be no powerful existence in the city.
