Then, the fire-type mutant used the power of fuel and the entire valley quickly caught fire from top to bottom. The flames illuminated half of the base.

Wen Yubai was more than a thousand meters away from the south wall. She could not hear the screams of the mutant rats after being burned, but she "saw" the mutant rats rolling in the sea of ​​fire, "looking" at them in great pain, which meant that the fire could burn the mutant rats to death.

But the mutant rats were too smart. When the fire suddenly started, the mutant rats that were farther away from the passage rushed to both sides of the valley. After they were out of the range of the fire, they rolled on the ground and put out the fire on their bodies.

The group of mutant rats that were still very close to the burrow quickly dug holes and hid back in the burrow they came from before the fire reached them. Among them was the mutant rat king.

Wen Yubai felt sorry to "see" that the mutant rat king escaped so easily, but she was also mentally prepared that the mutant rat king would not die so easily.

She counted them and found that the number of mutant rats that died in the valley fire was less than 300. It was not worth pouring so much fuel to burn only more than 300 rats.

After the fire broke out in the valley, the thermal imaging detector on the watchtower turned red, and Captain Fu and his men could not tell how many mutant rats were burned to death.

The thermal imaging detector was also unable to "see" the mutant rat group's passage. Shortly after they set fire to the valley, the mutant rat group changed direction and dug holes along the mountain road to the other side. Wen Yubai estimated that the mutant rat group was planning to attack the gate of Base No. 5.

Base Captain Fu and his men saw from the light curtain that some mutant rats were fleeing out of the valley. They only had a rough idea of ​​how many had fled. Base Captain Fu had already broadcast the communication to the western battlefield, asking them to prepare for battle, so there was no need for Wen Yubai to remind them.

This time, the mutant rats dug the hole even faster than before, and in less than five minutes they reached the side of the road leading to the mountain.

Then the mutant rats surged out like a flood, rushing directly up the mountain road and rushing towards the gate of the base, without stopping like they did before in the valley.

Under such circumstances, it would be too late to set a fire, and it would also easily backfire, so the people on the southwest front faced the mutant rat group head-on.

At this time, the mutant rats that escaped from above the valley also began to climb over the southern city wall.

Although these mutant rats are larger than ordinary house cats, they are not slow at all in climbing over the wall.

Wen Yubai "saw" it clearly. The claws of these mutant rats were as powerful as hooks. They climbed up the earth wall easily. Wen Yubai "saw" Wen Jinsong and others raising their knives to face the mutant rats.

Because of the fire, the number of mutant rats rushing towards the south wall was not large, probably only two or three thousand.

There were nearly a thousand people on the southern battlefield. They were all wearing protective clothing and protective helmets made by Wen Yubai, so they were not at a disadvantage against the small number of mutant rats.

However, the situation at the west gate of the base was not good. Although the number of defenders there was the largest, with nearly 3,000 people, the mutant rat king had moved here, and there were more than a dozen level 2 mutant rats in the mutant rat group. Mutant rats continued to pour out of the cave, and people and mutant rats fought in a group.

At the beginning, humans had the upper hand, but gradually, as the number of mutant rats increased, humans began to lose the upper hand.

Many people were pounced on and bitten by swarms of mutant rats. If they were not wearing protective clothing, they would most likely have died at the hands of the rats.

Seeing that fighting had already begun in the southwest, Wen Yubai could no longer sit still. She asked Base Commander Fu, "Base Commander, please let me go down and join the battle."

Base Captain Fu has been staring at the thermal imaging detector screen since Major Pei left the watchtower. After hearing Wen Yubai's application, he waved to her.

Wen Yubai immediately walked over to him. Base Chief Fu pointed at an image and said to her, "This is most likely a mutant rat king. As soon as we started setting the fire, it dug a hole and got in. Then it dug another hole from the valley and rushed straight to the gate of our base. It's very cunning. You go to the gate of the base first. I will notify Major Pei to rush over as well. You must find a way to get rid of it."

Wen Yubai naturally followed the order and went down from the watchtower. Although she was not as graceful as Major Pei, she was also quick and agile. She slid down to the ground along the metal pillar outside the watchtower with a "whoosh". Then she jumped into the car under the watchtower and rushed to the gate of the base.

Before Wen Yubai's car saw the gate of the base, the golden flying knives had already struck like lightning, killing the mutant rats around her.

She estimated that there were too many mutant rats at the gate of the base, and the crowd could not stop all of them. Many mutant rats had already rushed into the base.

No matter how powerful Wen Yubai's gold element was, her group attack skills were far inferior to those of Major Pei. The mutant rats were rushing into the base in all directions, and she had no way to stop them. She could only kill the mutant rats within her range.

When she killed her way there, she arrived at the gate of the base and saw that the place was in chaos. Most of the fighters were trapped by mutant rats.

The base team defending this side of the base gate are the Fourth and Fifth Regiments. People from the Flame Dragon Mercenary Group, as well as Jiang Tianyan and others are also here.

Wen Yubai saw the situation on the battlefield and guessed that the people on this side of the battlefield were assigned positions according to their combat power. The strong ones were in the front row, and the weak ones were in the back row.

Wen Yubai couldn't tell whether there was a problem with this formation. They were dealing with a large number of fast-moving mutant rats. The people in the front intercepted the high-level mutant rats, and the people with weaker combat power in the back only needed to kill the low-level mutant rats.

But in this way, the high-powered psychics in the front were held back by the high-level mutant rats, and they were unable to kill too many mutant rats, so a large number of mutant rats rushed to the rear.

The psychics in the rear were mostly level zero and early level one. They did not have the ability to kill a mutant rat quickly, so they were surrounded by a group of mutant rats.

When Wen Yubai arrived at the battlefield, he saw that the mutants in the back row were covered with mutant rats, and some were rolling on the ground.

If they hadn't been wearing protective clothing, Wen Yubai estimated that these people would have turned into bones. Even so, several people had already paid the price with their blood.

Seeing the situation on the western battlefield getting serious, Wen Yubai didn't care about the mutant rat king for the time being. He just wanted to eliminate as many mutant rats as possible that had poured into the base.

The metal knife was flying in the air, and soon those low-level psychics who were entangled by the mutant rats and were crying out for help suddenly found that the mutant rats on their bodies suddenly fell off and lay on the ground motionless.

When they looked up, they saw a young woman wearing no protective clothing but only combat clothes walking out from the group of mutant rats. The mutant rats around her fell to the ground on their own, and the mutant rats on them also died.

The author took a day off yesterday, but after exchanging points for a leave application, he found that he didn’t know how to leave a message on the note to tell all book friends that the author wanted to be lazy for a day and not to wait for updates.

Thank you Mimi’s Ruby dear for the reward and support the day before yesterday.
