After becoming a cultivator at the spirit sea level, Lu Qing had a better understanding of the power system of cultivators.
The level of the spirit sea was related to the cultivation of the cultivator. The Qi refining stage was the beginning, where the Qi was absorbed into the body. The foundation establishment stage was to train the cultivator's body and transform the body into a state suitable for cultivation; The initial enlightenment stage was to strengthen the soul, similar to the foundation establishment stage. It was to strengthen the cultivator's soul to the point where it could be cultivated further. And because the spirit was built on the physical body, the initial enlightenment stage had to be built on the foundation establishment stage.
