The psychic attacker takes action, and killing zombies and rats on such high efficiency and large-scale scope has greatly improved morale.

With the help of these psychics, the elite troops formed by the coalition forces have also continuously broadened the front line and posed a greater threat to zombies and mice.

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

No one doubted that at this pace, they were able to clean up the entire zombies and mice in the cave.

However, looking at all this, Ye Feng frowned. Although their speed of killing enemies was getting faster and faster, there were still too many zombies and rats.

Even if all the elite soldiers come down and slaughter them day and night, it will take a day and a night to kill so many zombies.

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

Sure enough, five minutes after Ye Feng's guess, the zombie mouse took a new move.

Originally, these zombies and mice rushed up frantically when they saw the soldiers on their side.

However, at this time, these zombies and mice changed their previous madness, from attacking to constant harassment.

As they continued to run, the difficulty of shooting for their soldiers was greatly increased. Moreover, a large number of zombie mice no longer attacked head-on, but climbed up above them along the walls of the cave, and then jumped down.

Such an attack made these soldiers very uncomfortable. Now they not only have to deal with the zombie mice rushing forward, but also constantly shoot the mice climbing up the wall. Otherwise, when they come to the top of their heads, they will cause great trouble.

It can be said that the change in the attack method of zombie rats directly reduced the attack efficiency of their own soldiers by half.

The changes in the zombie and mouse were clearly presented to us this time. In this head-on battle, Ye Feng could see more things.

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

Moreover, judging from the reaction speed of these zombie mice, the real commander hidden behind the scenes is not here, but is remotely controlled by these fourth-level mice. Otherwise, it would not have been delayed for so long before these zombie mice were adjusted.

This is also the result that Ye Feng is most reluctant to see, because in this way, he will be unable to carry out the beheading operation.

Just as Ye Feng frowned, the zombie mice in front of him changed again, and their speed of digging the cave began to accelerate.

Originally, these mice were just digging with their claws, so they did not dig too fast.

However, they have now changed the way of digging. Many zombies and mice will drill directly into the surrounding walls and tops and then dig from the inside.

With the combined efforts of many zombies and mice, they can quickly dig out a partition inside the wall and the rock formation at the top.

In this case, the entire area would collapse, and large areas of rocks and soil would fall easily.

Then the zombie mice below will rush up and transport the excavated rocks and soil through the channels on the other two sides.

After changing the way of digging, the zombie mice have increased their digging efficiency by at least five times.

If there is anything wrong with this excavation method, it is that the noise is too loud, especially when more than a dozen tons of rock and soil at the top of the cave fall, the entire cave is shaking slightly.

If zombies and mice had used this method of digging from the beginning, they would have been discovered long ago, but now that things have been exposed, they have no worries.

Not only Ye Feng saw these changes in front of him, but even others could see them clearly. Therefore, the originally relaxed and happy expressions on the faces of these soldiers changed instantly and became extremely solemn.

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 feel a little anxious.

However, they had no choice but to kill zombie rats desperately. And sadly, even though their killing efficiency is already very fast, they still feel powerless when facing the dense zombie rats like a tide.

"Boss, this won't work! I'm afraid that if we didn't kill all these zombies and mice, the base above would be dug up by them." Xu Youcai said anxiously.

If the base above collapses, they will be buried alive in an instant. It would be strange if Xu Youcai is not nervous.

On the other hand, after this period of recovery, Yiyalan's face had become much rosy. At this time, she also looked at Ye Feng, but there was no rush in her beautiful eyes, but there was a hint of expectation.

Of course, she was not expecting the cave to collapse and bury them alive, but looking forward to Ye Feng coming up with a good solution.

No girl is in love with her, even a mature beauty like Iyalan is not immune to the vulgarity. Of course, she hopes that the man she likes will show heroism and can turn the tide at the most critical moment.

Under Yiyalan's anticipated gaze, Ye Feng did not disappoint her. After pondering for a moment, he said to Xu Youcai: "You go and notify the commander of the coalition forces and let him come over. We cannot let the situation continue to develop like this. We must stop these zombies and mice from digging the cave."

"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.

"Hello, General Ye Feng! My name is Lu Yang. Before I came down, Lieutenant General Haihua asked me to obey your arrangements in everything. I don't know what you have to give." Lu Yang saluted Ye Feng and said politely.

Hearing the other party say this, Ye Feng immediately replied with a military salute, "General Lu Yang, I dare not take it. You have seen the current situation. I want to discuss with you how to curb the actions of these zombies and mice."

"General Ye Feng, then I wonder if you have any good ideas?" Lu Yang asked immediately after hearing Ye Feng say this.

To be honest, the series of changes in the zombie rat just now really made him feel a little unconscious, let alone any good solutions.

"I dare not take a good idea. It's just a stupid solution. 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 he was. The other party really had a solution and hurriedly said, "I hope to hear it carefully!"
