The Ability's side of the attack, such a high efficiency and a wide range of killing zombie rats, has a great morale boost.

And with the help of these supernatural people, the elite division formed by the coalition forces has also continued to broaden the battle line, posing a greater threat to the zombie rats.

It can be said that everything is moving in a good direction.

No one doubted that at this pace, they would be able to clean up the entire cave of zombie rats.

However, looking at all this, Ye Feng's brows furrowed, although their killing speed was getting faster and faster, there were still too many hundreds of millions of zombie rats.

Even if all the elite soldiers came down and slaughtered day and night, I am afraid that it would take a day and a night to kill so many zombie rats.

However, what they lack most now is time, not to mention the commander behind these zombie rats, how can they watch them slaughter these zombie rats!

Sure enough, five minutes after Ye Feng guessed like this, there was a new move on the zombie mouse's side.

Originally, these zombie rats, after seeing the soldiers on their side, all pounced on them frantically.

However, at this time, these zombie rats have changed their previous madness, from attacking as if they were dead, to constantly harassing.

As they keep running, it will be much more difficult for their soldiers to shoot. And a large part of the zombie rats, instead of attacking head-on, climbed above them along the walls of the cave, and then jumped down.

This kind of attack made their soldiers very uncomfortable, and now they not only had to deal with the zombie rats rushing in front of them, but also constantly shot the rats that climbed the wall, otherwise it would cause great trouble when they jumped down overhead.

It can be said that the change in the attack mode of the zombie rat directly reduced the attack efficiency of its own soldiers by half.

The changes of the zombie rats, this time they are presented in front of him very clearly, and in this kind of hard-fought battle, Ye Feng can see more things.

He found that among these zombie rat groups, there were some fourth-order zombie rats hidden. The attack of the rat swarm was commanded by these fourth-order zombie rats.

And judging from the reaction speed of these zombie rats, the real commander hidden behind the scenes is not here, but is remotely controlled through these fourth-order rats, otherwise it would not have been delayed for so long before these zombie rats were adjusted.

This was also the result that Ye Feng was most unwilling to see, because in this case, he would not be able to carry out the decapitation operation.

Just as Ye Feng frowned, these zombie rats in front of him changed again, and the speed at which they dug the cave began to increase.

Originally, the rats were only digging with their paws, so they didn't dig too fast.

However, they have now changed the way they dig, and many zombie rats will burrow directly into the surrounding walls and tops, and then dig from the inside.

With the combined efforts of many zombie rats, they were soon able to dig a partition layer into the wall and the rock layer at the top.

In this case, the entire area will collapse, and large swaths of rock and dirt will easily fall down.

Then the zombie rats below will swarm up and transport the excavated rocks and dirt through the passages on the other two sides.

After the zombie rats changed their digging methods, their mining efficiency increased by at least five times.

If there is anything bad about this excavation method, it is that the movement is too great, especially when a dozen tons of rock and dirt fall from the top of the cave, and the whole cave is trembling slightly.

If the zombie rats had been digging like this in the first place, they would have been discovered a long time ago, but now that the matter is revealed, they have no scruples.

These changes in front of him were not only seen by Ye Feng, but even other people could see them clearly, so the originally relaxed and happy expressions on the faces of these soldiers changed in an instant, becoming extremely dignified.

Whether it was the surrounding walls or the top of the cave, the fall of every huge rock seemed to hit their hearts, making them a little anxious.

However, they have nothing to do but desperately kill the zombie rats. And sadly, even though their killing efficiency is now very fast, there is still a sense of powerlessness in the face of the tide, dense zombie rats.

"Boss, you can't go on like this! I'm afraid that if we don't kill all these zombie rats, the base above will be dug up and collapsed. Xu Youcai said anxiously.

If the base above collapses, they will also be buried alive in an instant, so it's no wonder that Xu Youcai is not nervous.

On the other side, Yi Yalan's face had become a lot more ruddy after this period of recovery, and at this time she also looked at Ye Feng, but there was no hurry in her beautiful eyes, but there was a trace of expectation.

Of course, she didn't expect the cave to collapse and bury them alive, but she expected Ye Feng to come up with a good solution.

Which girl is not pregnant with spring, even a mature beauty like Yi Yalan is not exempt from vulgarity. Of course, she hopes that the man she likes will show heroism and be able to turn the tide in the most critical time.

Under Yi Yalan's expectant gaze, Ye Feng did not disappoint her, and after a moment of silence, he said to Xu Youcai: "You go and inform the commander of the coalition forces and ask him to come over, we can't let the situation continue to develop like this, we must stop these zombie rats from digging caves." ”

"Okay!" After Xu Youcai agreed, he immediately got into the crowd.

Not long after, an officer with the rank of major general followed him and came to Ye Feng's face.

"General Ye Feng, hello! My name is Lu Yang, and before I came down, Lieutenant General Haihua asked me to obey your arrangements in everything, and I don't know what you have to say. After Lu Yang saluted Ye Feng with a military salute, he said quite politely.

Hearing what the other party said, Ye Feng immediately returned a military salute, "General Lu Yang, don't dare to make arrangements, you have also seen the current situation, I want to discuss with you how to curb the actions of these zombie rats." ”

"General Ye Feng, I don't know if you have any good ideas?" Hearing Ye Feng say this, Lu Yang immediately asked.

To be honest, the series of changes in the zombie rat just now really made him a little uncomposed, let alone have any good ways to deal with it.

"I don't dare to take a good idea, it's just a stupid idea, and I don't know if it works." Ye Feng shook his head and said.

Hearing Ye Feng's words, Lu Yang didn't know where the other party really had a way, so he hurriedly said, "I want to hear it!" ”

"It's easy!" Ye Feng said and pointed to the passages on the other two sides of the cave, "As long as we send troops over and control these two passages, so that the zombie rats cannot transport these boulders and dirt excavated, we can curb their movements to a certain extent." ”
