[The New Year has passed, resuming the update of chapters with 3,000 characters!!!]
The physical trial of Death Qi is an invocation of a deeper metamorphosis of flesh and blood, from life to death, and from death to life, alternating between the Qi of life and death and keeping the body in a dynamic balance relative to equilibrium.
With the sensation of Death Qi, one can continuously expel the decaying flesh and blood within the body, always maintaining the vitality of the flesh!
Similarly, this is also the basis for Flesh Rebirth. Xiao Chen's flesh was sturdy, with an astounding recovery force from injuries. Even now, should his limbs be severed or his hands smashed, he could rely on the blood energy within his body for rebirth, all because of the boon of vital flesh.
Only by perceiving life and death can one truly control oneself, Blood Rebirth!
