"To have a part of your original body with you, it can be anything from skin to blood, even a very minuscule amount would do.
If you have that, then once your soul is healed, in case it was damaged too, you connect with it on a spiritual level and after that—your whole body will regenerate to its original state.
This method is only possible for high realm cultivators, where physical injuries heal in mere seconds.
And considering my realm, I can regenerate myself from a single dried drop of my blood, much less a fully preserved one, which I have kept till now."
Jiang Hao was stunned. He was sure he hadn't seen any blood drop inside the ring. He instinctively checked again, as he truly wanted to see the blood of a cultivator who had reached the peak of everything.
