During these five days, Ye Feng would observe the tide of corpses every night.

On the third day, Ye Feng relied on his powerful spiritual power to find a mouse that reached the fourth level in the vast tide of rats.

Even if such a mouse reaches the fourth order, it is insignificant among the huge group of rats.

However, Ye Feng keenly captured a very important information when the appearance of this fourth-order mouse.

Moreover, during the observations in the next two days, Ye Feng gradually discovered more fourth-level zombies and mice.

In order to confirm his thoughts, Ye Feng no longer only observed the zombies, but also went deep into Yunqing City during the day to observe the zombies.

During these observations, Ye Feng's conjecture was confirmed because Ye Feng also discovered some zombies that had reached the fourth level.

Although among the tens of thousands of zombies, perhaps only one has reached the fourth level, this is a clear signal, indicating that the zombies are likely to be promoted to the fourth level on a large scale, and thus enter the middle stage of the end of the world.

If this is true, then these zombie mice attack every day, which makes it understandable.

Obviously, the opponent wants to use the continuous attack to delay the pace of the coalition forces. As long as it can delay the zombies entering the fourth level on a large scale, it will become extremely beneficial for those zombies and mice.

First of all, as the zombies enter the fourth level on a large scale, the overall strength of the rat group will also make a qualitative leap.

Second, when the zombies are promoted to the fourth level, a large-scale zombie tide will trigger. At that time, it will not be the only ones who attack Yunqing City. If the other party’s commander has wisdom, this excellent opportunity will definitely not be wasted.

Of course, although the above two points are the reason why the other party tried so hard to delay, Ye Feng vaguely felt that things should be more than that simple.

Because there are many ways to procrastinate, the other party can constantly send zombies and mice to harass them. If a small part is sent every day and constantly harassing them on the periphery, the effect will definitely be better and the damage will be much less.

With the wisdom shown by the other party, it is impossible to imagine these things, but the other party still does this, so there is a high possibility of greater planning.

Of course, no matter what the other party wants to plan, the zombies will enter the fourth level and a large-scale zombie tide is about to break out. This is almost a foregone conclusion, and the other party will definitely make good use of this opportunity.

Therefore, Ye Feng felt that the alliance was necessary to attract high standards and prepared in advance.

......

"General Ye Feng, are you sure that your speculations are correct?" In the office of the top leaders of the coalition forces, Hai Huadong looked surprised after reading the information in his hand.

Of course, after saying this, he also felt that his words were a little abrupt, so he quickly added: "General Ye, I just want to confirm it, don't get me wrong."

Ye Feng nodded lightly and expressed his understanding, "These are my speculations, and I dare not confirm 100%. Of course, there are definitely more than 90% of the confidence. Zombies are about to enter the fourth level on a large scale. You can confirm this by sending people into the city and conducting a detailed investigation."

"There will definitely be an unprecedentedly large corpse tide. You should know that after the psychics enter the fourth level, their strength will have a qualitative leap. This leap is not only owned by us humans, but also by those zombies. Although the total number of troops here will exceed one million, we cannot be taken lightly, especially since we have a large number of people, the tide of corpse will naturally be more."

After hearing Ye Feng say this, Haihuadong immediately realized the seriousness of this matter. If the zombies are really promoted to the fourth level and a super-large tide of corpses breaks out, it will definitely be a disaster for their coalition forces.

Not to mention anything else, just their coalition forces are camping on the periphery of the base, and even the city walls are not as fatal as this.

Could it be that they really rely on the fortifications made of sandbags to resist the overwhelming tide of corpses?

You know, the super-large zombie tide caused by the promotion of zombies is not like zombie mice. It ends in an hour and is likely to last for several days. If there is no city wall, how can they resist those tireless zombies with their flesh and blood?

After thinking of such things, Hai Huadong's face became a little ugly, "General Ye Feng, I'm afraid I can't entertain you anymore. I will hold a meeting immediately to arrange defense work."

"Yeah!" Ye Feng nodded and said, "Actually, you don't have to worry too much. According to my estimate, there is still one week before the zombies are promoted to the fourth level on a large scale. We have plenty of time left. As long as you launch various bases of the coalition forces to build a wall, there is still no problem."

Hearing Ye Feng's reminder, Hai Huadong's face suddenly calmed down a lot. After nodding gratefully to Ye Feng, he hurriedly left the office.

Looking at Hai Huadong's departure back, Ye Feng shook his head. In the end, he still failed to express his guess about the zombie rat.

After all, it was just a guess. It would be useless to say it before you figure out what the other party wanted to plan. It would be of no use other than adding trouble to Haihuadong.

Soon, Ye Feng also left the office in Haihua East and returned to the place where the army camped.

Haihuadong was very efficient. Less than five minutes after Ye Feng returned to the battalion commander, a sergeant hurried to various military camps.

Then these messengers were brief in language and told me that the zombies were about to break through the fourth level on a large scale and would have a super large corpse tide.

Even if Ye Feng was inside the tent, he could clearly hear the uproar from various bases outside.

Obviously, this incident has brought great impact to all bases.

All bases have experienced the massive zombie tide caused by the massive advancement of zombies. Of course, they know how terrifying that zombie tide is. Moreover, it is said that after these zombies enter the fourth level, they may undergo qualitative changes like humans.

And they don’t even have a city wall here now. It would be strange if these soldiers and officers could be calm when they heard this news.

Of course, the next order from the senior coalition leaders immediately made these people feel much more at ease, that is, to build the city wall.

According to the plan of the senior coalition forces, another city wall will be built outside the Yunqing City base to enclose all the tents.
