Because Wen Yubai had been using her mental power to search for the mutant rats, she didn't notice when Major Pei came over, but she wasn't scared either.

"No, I'm just a little worried and feel a little bad." Wen Yubai said meaningfully.

"Do you feel anything?" Major Pei asked sensitively.

Wen Yubai heard something in his question, so he looked up at his expression and found that he looked very serious.

Wen Yubai began to suspect that he might have misunderstood something. He always thought that he was a mutated psychic whose only ability was to control the air and turn it into wind energy, and he had no ability to perceive mental power.

But she didn't know much about wind-type psychics. How could she know whether their perception ability would increase as their ability level increased?

Judging from Major Pei's expression, he might also feel that tonight might not be peaceful.

"Did you feel something too?" Wen Yubai asked instead of answering.

Major Pei may have been afraid of affecting others, so he did not answer her question, but Wen Yubai saw a word "yes" in his eyes.

"It shouldn't be that fast. Do you want to take a break?" Major Pei asked in a low voice.

The mutant rats were approaching them, so Wen Yubai had no mood to rest.

"I think you should look more carefully." Wen Yubai signaled him to go back and observe quickly.

About an hour and a half later, when Wen Yubai's mental power was finally able to "see" the situation underground, the mutant rats' tunnel had almost reached the foot of the mountain.

After the mutant beast in the front activated its superpowers, the soil in front of the cave seemed to become very soft, and the other mutant rats easily pulled the soil back.

The mutant rats moved extremely quickly. In less than a minute, they had dug out a hole about one meter in diameter and more than two or three meters long.

The movements were so fast that it seemed as if they did not need to stop at all and kept moving forward.

The leading mutant rat king seemed to be able to feel the terrain of the ground. After the tunnel was dug to the foot of the mountain, it stopped digging forward and started digging towards the ground.

It was winter at this time. Due to the strange changes in the heaven and earth, the plants that had not lost their leaves in winter in previous years were now withered, and dead branches and leaves were everywhere on the mountains and hills.

Wen Yubai felt that the mutant rat king seemed to have some special identification method. He dug up from that position and entered the entrance of the valley. There were withered bushes there, which could completely cover their movements and could not be captured by satellite monitoring.

Wen Yubai watched with his own eyes as the mutant rats poured out of the passage like a flood, and quickly poured into the valley under the cover of the bushes.

Wen Yubai looked at Major Pei and Base Captain Fu. The two were looking around the base with binoculars, completely ignoring the valley at the foot of the base.

Wen Yubai thought of setting fire to the valley to kill the mutant rats lurking in the valley.

Although this method is somewhat dangerous and can easily cause fire to the base, with the presence of Major Pei, a wind-type mutant, tragedy can be avoided.

But the biggest problem is how can she hint to Captain Fu and the others that the mutant rats are lurking in the valley without exposing her psychic abilities.

Because of this, she was in a daze for two minutes, and "saw" that the number of mutant rats pouring out of the cave had exceeded 500, but there were still an endless stream of mutant rats pouring out of the cave, gradually spreading towards the mountain road of the base gate.

During this time, none of the mutant rats made much noise during their movements, and the people in the watchtower remained unaware of anything. Major Pei and Base Captain Fu's telescopes did not see any important places at all.

The worst thing was that Li Haixin went to the next floor to rest, leaving her without anyone to use.

The last time the mutant ant colony appeared too suddenly and the situation was too dangerous, Wen Yubai had to react immediately. Major Pei did not ask her how she discovered the mutant ant colony afterwards, but instead made her wonder if he knew something.

So Wen Yubai really didn't dare to move, but if she didn't move, she would lose the initiative, so she was a little anxious.

"I thought of a question." Wen Yubai finally couldn't help but speak.

Although she tried hard not to let her voice sound anxious, it was so loud that not only Base Captain Fu and Major Pei, but even those who were able to leave their work turned around to look at her.

"What's the problem?" asked Base Captain Fu.

"I wonder if the mutant rats like to dig holes and move around like mice. Can satellite monitoring observe this?" Wen Yubai asked with some concern.

"We can scan up to eight meters underground, and so far we have found no signs of mutant rats digging holes," said Major Pei.

Wen Yubai originally thought that they had not thought of this and wanted to remind them. However, because satellite monitoring has this function, they did not notice it and thought that the mutant rats would not come in by digging holes.

Wen Yubai frowned. "Just because we didn't see it doesn't mean it doesn't exist. Satellite monitoring can only detect up to eight meters deep. What if the mutant rats dig holes from below eight meters?"

Base Captain Fu and Major Pei's faces changed slightly after hearing this. The other four were observing the people outside with binoculars. Although they did not turn around, Wen Yubai found that their actions had also changed. The binoculars turned from looking into the distance to looking at their feet.

Soon, the observation soldier who was observing from the south shouted loudly: "Report, there are many mutant rats in the valley."

Base Captain Fu and Major Pei immediately strode to the light curtain and ordered, "There is something going on in the valley. Aim the thermal imaging detector there immediately."

In fact, they didn't need to give any orders. After hearing their conversation, Adjutant Meng, who was sitting in front of the light curtain, quickly adjusted the camera. Before the two of them walked in front of the light curtain, the image of the valley in the dark appeared in front of everyone.

Everyone's faces changed drastically after seeing clearly, because the light curtain was filled with densely packed red mutant rats, which almost made Wen Yubai's claustrophobia come back.

"Group one, group one, there is a group of mutant rats in the valley, attack with fire immediately according to the plan." Base Captain Fu immediately turned on the satellite watch and gave orders to the other end.

"Yes." Captain Shan's loud voice came from the other end.

Major Pei saluted Base Commander Fu, walked out of the command room quickly, jumped off the watchtower, then used the wind energy to calmly fly through the air and landed in front of the south wall guarded by Captain Shan and his men.

At the same time, Base Captain Fu sounded the alarm, and a sharp long whistle rang out throughout the base.

Even though he was on the watchtower in mid-air, Wen Yubai could see the uneasy commotion in the base. Presumably, the people in the base knew what this alarm meant and quickly hid in the safe houses.

Major Pei went to the south city wall to help in the battle. He was the best helper in setting fire to the mountain.

Wen Yubai "looked" at the members of his mercenary team. Everyone was in good condition, so he felt relieved and continued to use his mental power to "watch" the situation in the valley.

Although the light curtain is now showing one side of the valley, it is not as clear as what she can "see" herself.

Thank you Yi Hai Ting Feng for the monthly ticket.
