As Tiandao sent his palm slapping down, time accelerated, and the feeling that everything in the universe was changing at a rapid rate encompassed the Astral Ancestor.
This was the level 10 black magic—Withering of Time.
It was impossible even for one's martial will to exist for eternity. The martial will would also age as time passed. However, it would be at a much slower rate compared to the ageing of the physical body.
The Withering of Time could accelerate the ageing of the martial will, depleting the other party's lifespan. It would instantly turn one's consciousness into dust, leaving no damage on the physical body.
Tiandao was going to destroy the opponent's will and the use the Time Resurgence Technique to snatch his physical body.
Under this palm, the Astral Ancestor's will seemed to age through several years or several decades, as if it would disintegrate at any moment.
