Ten minutes later, when Major Pei drove over from the south, Wen Yubai had killed four to five thousand mutant rats by himself. Now there were only more than three thousand left on this side of the battlefield, which greatly eased the pressure on this side of the battlefield.

Major Pei drove the car directly to Wen Yubai and said without getting out of the car: "Let's go to the north quickly. The mutant rat king has seen that this side has been unsuccessful and has gone that way."

Wen Yubai naturally also "saw" the movements of the mutant rats, but she could not expose her psychic abilities, so she was anxious to kill all the mutant rats on this side so that she would find an opportunity to move to the northern front.

However, now that Major Pei was here, she could naturally get in Major Pei's car and go to the northern battlefield.

Base No. 5 is backed by a mountain, and there are cliffs on the northeast and northeast sides. When Wen Yubai and his companions arrived at the battlefield in the north, they saw groups of mutant rats jumping down from the cliffs and pouncing directly on the humans' heads.

I have to say one more thing here. Fortunately, everyone was wearing protective clothing and helmets, otherwise there would be a lot of casualties.

The arrival of Wen Yubai and Major Pei reduced the pressure on the northern battlefield.

When it comes to group killing, Wen Yubai is really not as good as Major Pei. However, in the middle of a fight between humans and rats, Major Pei cannot guarantee that his wind blade will not cause accidental injuries, so he has to restrain himself and cannot be as unrestrained as Wen Yubai.

But by the time they cleared a path and reached the wall, the mutant rat king had already disappeared.

Major Pei had to rely on satellite monitoring to locate the mutant rat king, but Wen Yubai had been "keeping an eye" on it.

The mutant rat king was too cunning. As soon as she and Major Pei arrived at the northern battlefield, it seemed to have discovered something and immediately led the mutant rats around the eastern wall.

Forty to fifty thousand mutant rats attacked the base from four directions, but the mutant rat king hid far away. In addition, it had earth-related abilities, so it was not easy for Wen Yubai and the others to kill it.

After Major Pei and Wen Yubai chased around the base, they confirmed that the mutant rat king ran away as soon as it sensed their presence.

The two men learned their lesson and no longer paid attention to the situation on the battlefield, but instead focused on the mutant rat king.

But every time, Major Pei flew to the mutant rat king's location with Wen Yubai in his arms, the mutant rat king cunningly burrowed underground.

Neither the wind blade nor the metal knife could hurt the mutant rat king.

Although Wen Yubai's metal flying knife chased along the hole in the ground, the mutant rat king cleverly misplaced his position. Although the flying knife still hit the mutant rat, the force of pursuit had weakened due to the change of track, and it did not cause much damage.

And after this experience, the mutant rat has been hiding in the burrow and never came out.

Even though the two of them killed all the mutant rats around them, the mutant rat king did not come out from underground. Instead, it fled in the opposite direction of the base.

As soon as the mutant rat king escaped, the entire mutant rat group seemed to have received some signal and dispersed and fled towards the base.

This battle with mutant rats lasted only more than two hours, and the mutant rat king escaped with most of the mutant rats.

Wen Yubai and Major Pei looked at each other, and both felt helpless.

"No wonder scientists say that mice are the second most intelligent creatures after humans. After humans become extinct, they are most likely to replace humans and become the intelligent creatures on the Blue Water Planet." Wen Yubai sighed.

After the end of the world, every time she cooperated with Major Pei, she could be said to be invincible, but this time there was nothing she could do.

"If we can't eradicate the entire population, there will probably be endless trouble. At least half of the mutant rats have escaped." Wen Yubai said.

"The most worrying thing is that it will go to other bases. There are no level three mutants in other bases. Even if there is only half of the mutant rat group left, with the mutant rat king here, I'm afraid those small bases around us will not be able to withstand it." Major Pei thought more broadly.

Wen Yubai's focus was on Base No. 5 and Base No. 1. As for those small bases, she would not worry about them unless the Lord God and the system asked her to do so, so she did not respond to this question.

After making sure that the mutant rats had retreated, Wen Yubai knew that cleaning up the battlefield and dealing with post-war matters were not her business. She parted ways with Major Pei and returned to the south city wall to find her companions.

The Wen family and the Future Era Mercenaries were safe and sound. Although the mutant rats first appeared in the valley on their side, because they had set fire to the Mountain Man Valley, the number of mutant rats on their side of the battlefield was the least.

The soldiers at the base were busy most of the night before they returned, but Wen Yubai and other members of the mercenary team went home early to sleep.

When Wen Yubai got up the next day, Wen Jinsong had already gone out to get information and came back. It was said that more than fifty people died in the mutant rat attack in the entire base.

"So many people died." Zhang Xiying sighed.

Wen Yubai glanced at her without saying anything. These people didn't know that in the previous life, this group of mutated rats broke into Base No. 5 unhindered and killed nearly 100,000 people.

One hundred thousand people versus fifty people, Base No. 5 in this life can almost be said to be unscathed.

This is because some people were reluctant to spend their crystal cores on purchasing good protective clothing, which is why so many people died.

The protective clothing made by Wen Yubai is only enough to be provided to the army and his own mercenary team.

Although some people specifically ask her for custom-made products, not many people come to her because she sets the prices so high that most people cannot afford it.

Among them, Wen Jinsong, whose charging price is only one-sixth of Wen Yubai's and whose gold-related abilities are second only to Wen Yubai, has become the most welcome person among all major mercenary teams.

Wen Jinsong actually earned 50,000 crystal cores with his protective suit. Wen Yubai was really shocked. He didn't expect that his father could earn so many crystal cores.

She only earned 10,000 yuan from custom-made products, while the Future Mercenary Corps and the Base Army charged only half of that. All in all, she earned only a little more than Wen Jinsong.

There was no problem with the protective suits made by Wen Jinsong and Zhang Chungen, two second-level gold-type psychics, because the mutant rat king did not step into the base under the suppression of Major Pei and Wen Yubai.

In order to save crystal cores, some mercenary teams only buy protective clothing made by first-level gold-type mutants.

However, they did not expect that there were more than twenty level two mutant rats in the mutant rat group. Those who were wearing protective clothing made by level one gold-type mutants were in trouble when they encountered them, and their protective clothing was torn apart in an instant.

However, there were only a dozen or so people with special abilities who died in the mutant rat swarm, and the other thirty or so people who died were ordinary people in the base who did not hide in the safe house.

God knows if these people are tired of living and run outside the safe house to die.

Wen Jiangzhu and his son, as well as the ordinary people of the Future Era Mercenary Group who did not go into battle, did not do anything suicidal and just stayed in the mercenary group's building.

However, an ordinary member of the Wenyun Mercenary Team was bitten half-crippled. It was not known whether he wanted to die, but he left the Wenyun Mercenary Team’s base in a suicidal manner.

The base of the Wenyun Mercenary Team was defended by Wen Yubai himself, and even the fourth-level mutant rat king could not break it.
