"About ten kilometers." Cai Yao said with a slight pause.

"How do you know..."

Before Shen had finished speaking, he heard the roar of the guards.

"Report! The mutant herd still has ten kilometers to reach the capital gathering place! "

Shen Zhenguo looked at Cai Yao with an incredible look on his face.

Originally, he thought that Cai Yao was just an estimate, but even if it was estimated, it could not be so accurate, right?

"Cai Yao's ability is distant pupil. She can see things far away clearly." Wang Yi explained.

In fact, the effect of CAI Yao's distant pupil in the dark is not so good, mainly because the number of mutant herds is too large, even in this case of poor light, Cai Yao can also see vaguely.

"So it is." Shen Zhenguo's eyes flashed a look of thinking. Cai Yao's powers can be said to be generated for large-scale combat. Unfortunately, there is only such a CAI Yao. If there is one in his army, it will definitely play a vital role in his future plans.

However, he could only sigh to himself. Wang Yi would never give up such an important person.

"Chirp, chirp!"

At this time, a harsh sound suddenly sounded, the people on the wall, including those soldiers, were stunned, subconsciously looked up at the dark sky.

"Then... What's that noise?"

Li Hu's face was puzzled, but he instinctively felt something was wrong.

The voice of the mutant animal is roar, which everyone knows, but just now that voice is completely similar to the voice of birds.

"No! There is a large group of UFOs in the air approaching quickly! "

Cai Yao said with a tight look, just now she put all her attention on the ground, but when she heard the sound, she subconsciously looked up into the air and found a large gray flying object approaching at a high speed.

The speed is far beyond Cai Yao's cognition!

"It's a mutant bird!"

Cai Yao said, biting her teeth.

"How could there be mutated birds?" Li Hu's face is full of disbelief.

"Birds are also animals. If you don't see them, it doesn't mean they don't have them."

Wang Yi shook his head in a deep voice. It was obvious that Wang Yi was much calmer than others. However, Wang Yi did not expect that mutant birds appeared at this time, and Shen Zhenguo's scouts didn't notice at all.

You should know that in the previous life, among the mutated animals, the biggest casualty to the survivors was not the large animals such as mutated boa constrictor or mutated bear, but the mutated birds!

Because of the special reasons of mutant birds, they can fly, and even have faster flight speed than before the outbreak of doomsday. Therefore, all the ground walls cast by human beings have no defensive effect on mutant birds.

Mutant birds can cross the city wall and directly attack the survivors inside the city wall, but Wang Yi didn't expect that they could form a scale at such an early time, and there are still millions of them!

Hoo... Hoo

Just at this time, a violent wind suddenly sounded. The soldiers on the wall only felt a hurricane blowing down from the top of their heads. Some soldiers were blown upside down, and even a few soldiers were blown down directly from the wall. You know, this is a distance of more than 30 meters, and the soldiers who fell down were directly thrown into meat mud.

"No! Everybody get down

As soon as Wang Yi's face changed, he immediately roared with a ferocious voice. As Wang Yi's voice went out, the soldiers on the wall immediately responded and went to the ground one by one. But after all, the wall was so wide, and no one thought that there would be a so-called mutant bird air attack just now. They all thought that the danger came from the ground, so they stood in a very dense position,

Only a part of the soldiers got down as they wanted, and many of them had no place to get down at all.

However, the reaction speed of several people around Wang Yi was not slow, especially Cai Yao was pressed by Wang Yi almost at the same time.

It's at this moment.

Whoosh, whoosh!

A dense burst of air burst out, and the air on the city wall was like a sharp arrow falling from the sky. One was gray and black, and the big one spread out its wings, which was ten meters wide. The small one almost caught up with a mutant bird with an open arm, and fell from the sky, directly on the soldiers on the city wall.

Click, click, click!

There was a sound of fragmentation. Looking around, the soldiers who didn't lie on the ground in time were taken from the city wall by the mutant birds one by one, and their shoulders were scratched. There was a sound of bone fragmentation.

"Help

"Help me!"

"Let go of me!"

With the sound of panic, Wang Yi felt the wind over him. He looked up and saw that hundreds of soldiers were brought directly into the air by the mutant birds.
