This cultivation technique does not conflict with the Thousand Evil Poison Technique he practices. Thousand Evil Poison Technique requires poison to improve cultivation and does not need to use Immortal Energy for cultivation.
However, the Qiankun Nine Palace Technique requires the combination of Immortal and Evil Qi to condense the Power of Life for cultivation.
Immortal Energy is everywhere in Taoyuan World, but Evil Qi is hard to find. According to the Qiankun Nine Palaces Technique Jade Scroll, Evil Qi is a rare thing in Taoyuan World, and once obtained, it must be cultivated to rapidly form the Qiankun Nine Palaces Technique.
Many past practitioners of Qiankun Nine Palaces Technique have given up due to the lack of Evil Qi.
