章 1077: The second stage of evolution

This discovery surprised Xu Cheng.

First of all, ultrasound was a basic characteristic of bats. Xu Cheng had it himself, and so did Chekhov. It seemed like the first ability that bats had when they discovered their potential was always ultrasound.

But what surprised Xu Cheng was that his ultrasonic wave now had a range of five kilometers!

Chekhov was two kilometers!

And other than the bat's ultrasonic ability, even Chekhov didn't have any other abilities.

But this Duke was different. It wouldn't be surprising if he blew up Chekhov and himself with the same ultrasonic system. After all, it was normal for an old monster who had lived for 200 years to have such genetic evolution.

However, he could fly like a bat and also drink its blood, which surprised Xu Cheng. Maybe the only thing that could keep him alive was this extreme blood-drinking ability?

Could it be that the gene excavation of a certain species also had different levels?
