If the Ghost Emperor discovers Su Yu's abilities, it would be troublesome.
This guy definitely has research on the Power of Time and might make specific arrangements against it.
Or the Ghost Emperor might find Su Yu's abilities too powerful and directly escape, remaining invisible, to avoid being detected by Su Yu.
If the Ghost Emperor remains hidden, no matter how strong Su Yu's Power of Time is, it would be useless if he can't find him.
At that time, the Ghost Emperor is in the dark, and Su Yu is in the light, eventually leading to an ambush.
Although even if Su Yu falls into an ambush and dies, he can still be resurrected, it is ultimately still a hassle.
Perhaps if he dies enough times, the Ghost Emperor would find a way to kill Su Yu permanently.
Actually, Su Yu has another option, which is to travel back further in the past, a year ago when he last faced the Ghost Emperor face-to-face.
