With the order of the coalition high-level was issued, the various bases were soon in action, and under the arrangement of the coalition high-level, some bases were responsible for collecting materials, some were responsible for transportation, and some were responsible for construction.

Maybe it is impossible for them to build a Great Xia in a few days, but it is much easier to build a city wall.

Because there is no technical content in the construction of the city wall, it only needs to be firm, and in this case, it is completely able to give full play to the huge numerical advantage of the coalition army.

Teams of soldiers were sent out, some of them going to the city, collecting the cement bricks of the collapsed houses and transporting them back in truckloads.

However, more teams still go to the mountains and forests around Yunqing City to mine mountain rocks and use large mountain stones as foundations, which is definitely the best choice.

And when these materials are brought back, they will be handed over to the base responsible for the construction of the city wall, and those soldiers will quickly start building with the construction tools and concrete provided here in Yunqing City.

Basically, every base has walls, and nine times out of ten of these soldiers have been involved in it, it can be said that these things are simply easy to do.

800,000 troops built the city wall together, and the speed can no longer be described as changing with each passing day, it is simply changing every minute and every second, and a city wall nearly 20 kilometers long is taking shape at a speed visible to the naked eye.

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

This is still a case where the tools are insufficient, otherwise it would be possible to double the speed.

When the various bases had dinner and looked at the wall that had replaced their original fortifications, everyone had a sense of steadiness.

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

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

This can be seen from the situation of defending against the tide of rat corpses that night, in the case of relying on the city wall defense, they have a shorter time to fight with zombie rats in close quarters, and there is less time, which directly leads to the fact that the defense time of each base is longer, and the defense is more relaxed.

After feeling this, the faces of both those officers and soldiers looked a lot 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 that have ambitions and want to gain a certain voice in the alliance, because they send a large number of soldiers, and even shake the foundation of the base a little.

If the degree of military strength is weakened by more than 20%, then in the face of this super-large corpse tide, I am afraid it will be dangerous.

After all, such a wave of corpses, people who can survive until now, have experienced it at least three times, and of course understand its horror.

Of course, what the members of the various bases thought in their hearts, Hai Huadong didn't know, but he knew that he was very happy.

Even regardless of the image, he came to the front line in person and found Ye Feng.

"General Ye Feng, this time it's really thanks to your reminder, otherwise, if we find out one day later, it will be more dangerous." Hai Huadong said with a grateful face.

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

Speaking of this, Ye Feng paused, but still said: "However, I feel that the crisis we are about to face is probably not as simple as just the corpse tide. After all, don't forget, our opponent is a zombie rat king with wisdom, and he sends zombie rats to death every day, is it really just a simple delay in time? ”

Ye Feng's words suddenly made Hai Huadong's face change slightly, what Ye Feng said was something he hadn't thought of before.

And if he thinks about it carefully, then the level of trouble encountered in this matter is probably far greater than he imagined before.

"General Ye Feng, did you guess something, or do you have any way to deal with it?" Hai Huadong asked with a little urgency.

However, under his expectant gaze, Ye Feng shook his head, "No, I don't have a clue at all, otherwise, I would have told you this morning." ”

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

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

"As long as we can contain this wave of corpses and still have the strength to fight back, then no matter what the other side wants to do, we can easily deal with it." Ye Feng opened his mouth to comfort.

"It's me who lost my temper." Hai Huadong took a deep breath, his expression returned to calm, and then continued: "Thank you General Ye for reminding me, in the next few days, in addition to arranging people to continue to build the wall, I will make some other arrangements, the good things we brought from Beijing have not been put to use, I think when the time comes, it will definitely bring a big surprise to the zombie rat king." ”

Hai Huadong also has his confidence when he says this, because there are a lot of good things in the armory of the Beijing base, not to mention anything else, just the hundreds of boxes of howitzers can easily bomb the place within three kilometers of the city wall back and forth several times.

Of course, Haihua East also thought of Ye Feng, the team brought by the other party was only 2,000 people, and it reached 27,000 troops, so the combat effectiveness can be imagined.

But in the past few days, he hasn't made a move, and he still felt a little confused before, but now he completely understands that Ye Feng also wants to keep a hand.

After thinking of these things, Haihua East felt even more at ease. With Ye Feng there, he felt that the pressure on his shoulders had been reduced by at least half.

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

Ye Feng also returned to the battalion commander after seeing that today's corpse tide had receded.

Over the next few days, the entire base was busy building defensive lines, and as time went on, the crowd became more and more nervous.

Because on the third day of their construction of the defense line, the zombies of the fourth order had become more and more obvious, and even during the day, they could see some scattered zombies gathering.

Obviously, this is a sign of a large zombie outbreak, and when these zombie animals gather to a certain number, they will actually attack.

This also made the atmosphere of the coalition even more tense, but fortunately, in the past three days, they have almost collected the materials to build the wall, and they can still continue to build.

As for how high a wall can be built before the corpse tide erupts, it can only depend on the will of God.
