But this is where the Martial Ancestor's brilliance lies: the "Self" is merely a temporary "Self," while the "External Items" are the true "Self."
It is completely a reversal of the usual way! Thus, yielding to Heaven to obtain the Dao Fruit becomes much easier.
At this moment, everything Xiao Chen is doing is the process of cultivation by defying Heaven.
Turning his true Self into dead wood, withdrawing Divine Sense and Life Essence completely, to create an "External Item." Then pouring Divine Sense and Life Essence into the Ancestor God Flesh Shell, temporarily creating a Self, in order to sacrifice this temporary "Self" to fulfill the "External Item" he crafted, to cultivate the true fruit in defiance of Heaven.
Xiao Chen is prepared to sacrifice the Ancestor God Flesh Shell to achieve the "External Item," which is also the like-dead-wood "Self."
