At the same time, these mutant beasts have stronger combat power and will also use superpowers to attack Xu Yi.

They cooperated well, which made Xu Yi feel the danger.

However, as the murderous aura continued to accumulate, Xu Yi became more and more braver in the battle, and began to force these mutant beasts to retreat.

They cooperated with each other and fought and retreated, which made Xu Yi unable to take advantage.

Although these mutant beasts have many wounds on their bodies, none of them are very fatal.

Xu Yi summarized that he could deal with two fourth-level mutant beasts at the same time, but even with his sharp sword, he could not kill any of them.

As long as he attacks one of them, the other three will decisively attack Xu Yi, forcing him to give up killing one of them.

If he killed one of them desperately, he would be injured himself.

Although the air shield is good, it is still difficult to prevent the attack of three and fourth-level mutant beasts at the same time.

Although Xu Yi has pills and medicines, he can quickly recover after being injured.

But no matter how fast it is, it will take some time.

Here, there are more than these mutant beasts, who will rush out at any time.

So, he can't let himself be hurt.

Even if he failed to kill any of them, Xu Yi was unwilling to hurt himself in the wild.

In the wild, the risk of injury is too high.

After the four mutant beasts were injured a lot, they decisively chose to escape.

If you continue to fight with Xu Yi, you will inevitably be killed by Xu Yi.

Even, they will be killed by other mutant beasts that suddenly appear.

Therefore, they decided to escape.

Xu Yi did not chase after him, after all, he didn't want to hurt himself.

Xu Yi thought it was already very good to be able to force these mutant beasts to retreat.

After greeting Tai Chi, Xu Yi continued to run wildly towards the direction of the railway.

If this place wasn't suitable for driving, Xu Yi would have taken out his all-terrain car.

Not long after running out, Xu Yi heard the screams of mutated birds coming from the air.

They seemed to have discovered the injured mutant beasts.

Xu Yi looked back and saw that more than thirty mutant birds all "smashed" towards the ground.

He was very glad that he did not chase and kill the mutant beasts, otherwise he might have been attacked now.

"Tai Chi."

Xu Yi shouted, and Tai Chi immediately jumped towards Xu Yi.

Xu Yi decisively activated the flying backpack behind him and flew directly at low altitude.

Because the mutated birds were too close to him, it was easy to find him.

His running speed is much slower than his flying backpack, so he just wants to take a look and start the flying backpack directly, preparing to use the speed of his flying backpack to widen the distance from those mutated birds.

After all, they attack those mutant beasts, and they must eat if they kill them.

Therefore, Xu Yi felt that this was the best time to escape.

Sure enough, Xu Yi did not notice the mutant birds catching up with him.

After flying quickly for more than ten minutes, Xu Yi raised the flight altitude a little.

However, just after raising the height, Xu Yi saw some huge black shadows appearing in the sky ahead.

That was another group of mutated birds, with only three.

But Xu Yi felt that their size was greater than that of large passenger aircraft.

This kind of mutated bird cannot be provoked.

God knows what level they are.

Therefore, Xu Yi chose to fly at low altitude very decisively.
