The so-called qi was the qi that formed and maintained the life activities of the human body!
Similar to spiritual power, there were two sources of spiritual power: innate spiritual power and acquired spiritual power.
Innate spiritual power – this kind of essence qi was born from the body. It was the basic substance of life. It was inherited from the parents, so it was called innate essence.
The spiritual essence of acquired spiritual power was contained in the food, medicinal herbs, or the spiritual qi that existed in nature. As this type of essence energy was obtained after birth, it was called acquired essence.
As for qi, it was the source of motivation for ancient martial arts secret techniques.
Qi and spiritual power were too similar. People often overlooked it when they were feeling the mysteries of the human body.
