The Demon Ancestor wanted to cultivate his own desires into entities to assist him, ultimately achieving a harmonious fusion to break through the Chaos Origin.
With Nezha's current comprehension and cultivation, he quickly understood the Demon Ancestor's idea. The method was not bad, but it couldn't compare to the Three Corpses Cutting Method because Luo Hou was defeated by Hong Jun.
Nezha completed the last piece of the puzzle regarding how to break through to the Chaos Origin while maintaining his self-awareness.
First, one must 'nurture' — cultivate one's emotions to make them more abundant. Then 'divide' — after excessive emotions separate from oneself, one still maintains a normal self. Finally, 'cut' — let the avatar with a single emotion, more aligned with the Heavenly Dao, carry out the cultivation that could erode humanity.
