When he awoke, Feng Lin discovered that it was unknown when he had floated up in the sky.
Spiritual qi formed a vortex, resembling a tornado that lifted him into the air.
A concentrated aura was emitted from him, causing ripples to form in the atmosphere.
He glanced at the time and discovered that for this bout of cultivation, he had unknowingly entered seclusion for about a month. He hadn't sensed any changes to his body at all.
For this point, it was completely different when compared to mythological gene cultivation which emphasized strengthening the mythological genes in one's body.
For ancient cultivators, they cultivated the cycles of energy within their bodies, matching it with the cycles of heavens and earth. They were able to breathe in the formless spiritual qi to replenish their energy consumption and enter a type of state where they could abstain from food.
