This is it, the Holy Fist!
How could one possibly fight and kill an Ultimate Dark Entity as vast as a mountain range without possessing a power that could rival it?
At the peak of the Secret Martial Art stand the Holy Fist, Tyrant Fist, and Extreme Fist.
It had fully entered a terrifying state akin to that of a god.
In terms of lifespan, so far, none who possessed the realm of the Holy Fist had died of old age; they had died in battles against Ultimate Dark Entities or drained to death in struggles against Calamity Source. Theoretically, as long as the will of the Holy Fist did not perish, they would not succumb to death, and their Qi would continue to circulate and grow.
