Gravis' mind stopped as he heard the old man's words.
How did he know!?
A ton of questions appeared in Gravis' mind, and he became nervous. This was not something simple! One of the Peak Sects knew that he had a beast body. If they decided to send a Peak Immortal King, everything would be over.
Yet, the question was, why didn't they? If they had known that he was a beast, why hadn't they arrived to kill him yet?
Gravis was sure that his secret couldn't have been found out just now. After all, there was no way that a Peak Immortal King was in such an unimportant and remote location.
This could only mean that the old man had noticed it back then. Additionally, the old man could have unveiled Gravis' status right then and there. At that time, Gravis would have been helpless against any Immortal King, and there had been a lot of them.
