Transcendent realm cultivators had an exuberant vitality and the ability to regrow severed limbs, so no matter how severe their physical injuries were, they could only consume their blood and Qi, unable to truly kill them.
However, if one's primordial spirit was obliterated and completely disappeared, the transcendent realm cultivator would die completely, leaving behind an "immortal" body.
In the various major systems, there were only two ways to kill transcendent Warriors:
First, by continuously striking, the martial artist's qi and blood would be worn down until he was exhausted. Then, he would dismember the martial artist and seal him.
Two, by using a special method, the martial artist's primordial spirit could be extracted, and after a long period of refinement, the primordial spirit could be obliterated to kill him. At that time, what was left of the martial artist was just a shell.
