Pain Tribulation

One of the 3 "tests" a cultivator must endure to progress to the next level of existence, namely the Heroic ranks and the Divine ranks.

Characterized by a cultivators flesh (anything "unfit" for the new form the cultivator will gain) being ripped from the bones, as well as said bones breaking in half, only to be remade by the cultivators Breath into the new, stronger form. Generally considered the easiest one.

"Like the dantian boiling away most of its impure "Breath" to reach a higher purity when it increased in rank, so did the body. Flesh was a mortal material, "Breath" was the true source of energy. All those impure body parts had to be expelled to form a purer body, able to successfully store "Breath" of a higher quality."

This Tribulation is known to kill nobles who have a weak pain tolerance, as it is entirely reliant on the cultivators remaining conscious.
