With the orders from the senior coalition leaders issued, each base soon took action. Under the arrangement of the senior coalition leaders, some bases were responsible for collecting materials, some were responsible for transporting, and some were responsible for construction.

Perhaps it is unlikely that they will build a Daxia building within a few days, but it will be much easier to build a city wall.

Because things like city walls do not have much technical content when constructed, they only need to be solid. In this case, the huge number of coalition forces can be fully utilized.

A team of soldiers were sent out, and some of these teams would go to the city to collect the cement bricks from the collapsed houses and transport them back.

However, more teams went to the forests around Yunqing City to mine rocks and use large pieces of rocks as the foundation. This is definitely the best choice.

When these materials are transported back, they will be handed over to the base responsible for building the city wall. The soldiers quickly started building with the construction tools and concrete provided by Yunqing City.

Basically, each base has a city wall, and most of these soldiers have participated in it. It can be said that these things are so familiar to do.

The speed of 800,000 troops built the city wall together could no longer be described as changing with each passing day. It was simply changing every minute and every second. A city wall that was nearly twenty kilometers long was forming at a speed visible to the naked eye.

By the evening, the city wall had been built at a height of two meters.

This is still the case of insufficient tools, otherwise it is possible that the speed will be twice as fast as possible.

When the various bases had supper and looked at the walls that replaced their original fortifications, everyone felt a sense of peace.

When they were at their base, these city walls were the best survival guarantee, so now they feel like this when they see the city walls.

In fact, the function of this city wall is really much better than fortifications.

This can be seen from the situation of defending against the tide of rats that night. With the defense of the city wall, they fought with the zombie mice for a shorter and less time. The direct result is that the defense time of each base is extended and the defense is easier.

After feeling these, both the officers and soldiers looked much better, at least they were not so worried about the upcoming super-large corpse tide.

Even compared to them, these people are more worried about their own bases, especially those with ambitions and want to gain a certain voice in the alliance, because they sent a large number of soldiers, which even shook the foundation of the base.

If the military power is weakened by more than 20%, then facing this super-large corpse tide, it will probably be in danger.

After all, people who can survive this tide of corpse have experienced it at least three times, so of course they understand the terribleness.

Of course, Hai Huadong didn't know what the members of each base were thinking, but he knew he was very happy.

He even went to the front line in person regardless of his image and found Ye Feng.

"General Ye Feng, thanks to your reminder this time, otherwise we would find out one day later, which would be a little more dangerous." Hai Huadong said with a grateful look on his face.

Ye Feng looked at the retreating rat tide and smiled and said, "General Hai is polite. I'm afraid you will find out in a day or two without my reminder."

Speaking of this, Ye Feng paused and said, "But I feel that the crisis we are facing is probably not just as simple as the corpse tide. After all, don't forget that our opponent is a zombie rat king with wisdom. It sends zombie rats to die every day, which is really just a simple delay in time?"

Ye Feng's words immediately changed Hai Huadong's face slightly. What Ye Feng said was something he had never expected before.

If you think about it carefully, the level of trouble encountered in this matter will probably be far beyond his previous imagination.

"General Ye Feng, have you guessed something or have you deal with it?" Hai Huadong asked slightly anxiously.

However, under his expectant gaze, Ye Feng shook his head, "No, I have no idea, otherwise I will tell you this morning."

Ye Feng's words immediately made Hai Huadong's face look a little ugly again.

"But you don't have to worry too much. No matter what the other party's conspiracy is, one thing that is certain is that the conspiracy was carried out under this super-large tide of corpse."

"As long as we can curb this zombie tide while leaving the extra energy to fight back, no matter what the other party wants to do, we can handle it easily." Ye Feng comforted.

"I'm losing my composure." Haihuadong took a deep breath, his expression calmed down, and then continued: "Thanks to General Ye for his reminder. In the next few days, in addition to arranging people to continue to build the wall, I will also make some other arrangements. The good things we brought from Beijing have not been used yet. I think that when I use them, it will definitely bring great surprises to the Zombie Rat King."

Hai Huadong said this with his confidence. There are a large number of good things in the arsenal of the Beijing base. Not to mention anything else, just hundreds of boxes of howitzers can easily bombard the city wall within three kilometers.

Of course, Haihuadong also thought of Ye Feng. The team brought by the other party reached 27,000 units with only 2,000 troops, so the combat effectiveness is conceivable.

But in the past few days, he has never taken action once. He felt a little confused before, but now he fully understands that Ye Feng also wants to keep one.

After thinking about these things, Hai Huadong became even more at ease. With Ye Feng around, he felt that the pressure on his shoulders was reduced by at least half.

Next, after the two talked a few more about defense work, Hai Huadong left. After all, his identity is still relatively sensitive, and it is not suitable to stay here all the time.

After seeing the tide of corpse retreat today, Ye Feng also returned to the battalion commander.

In the next few days, the entire base was busy building defense lines, and as time went by, everyone became more and more nervous.

Because on the third day of their construction of the defense line, the fourth-level zombies were becoming more and more obvious, and even during the day, some scattered zombies could be seen gathering.

Obviously, this is a sign of a large corpse tide. When these zombies gather to a certain number, they will launch real attacks.

This also made the atmosphere of the coalition even more tense, but fortunately, during these three days, they had almost collected the materials for building the city walls, and they could continue to build them.
