My Three Corpse Insect Cultivation Manual

Qi is divided into clear and turbid. Qing Qi is divided into yin and yang, five elements and twelve branches. It is called spiritual light when it is scattered but not gathered. All things have qi. If you pick it from innate things, you can get clear qi. If you pick it from acquired things, you can get turbid qi. You think this is a story about cultivating immortality, but it is actually a fantasy about cultivating oneself!
