It's worth mentioning that.
After reaching the Integration of Void Stage, aside from a few special cultivation techniques, most of them lost their effectiveness.
The so-called Integration of Void is refining one's own void and integrating one's own path. The best path is always the one walked by oneself.
"Since I became an immortal through the 'Ingesting Qi Decision', I shall take this as my foundation and develop my own cultivation techniques." Xuanqing made up his mind.
Ingesting Qi Decision makes one swallow a mouthful of innate energy to nourish the physical body and the god soul. When combined, they can shed the mortal body and achieve the immortal body.
"Great Immortal Zhenyuan once said that after becoming an immortal, one needs to cultivate the Three Flowers and verifying Gathering the Crown, and also collect the Gold, Wood, Water, Fire, and Earth Five Qi within their chest to verify the Chaoyuan Power."
