The thought of Yijin comes from Taoism and has the same origin as Guzhuangquan, both originating from the lineage of ancient body cultivation. The highest state is not that the vajra is indestructible, but that one enters the Tao through martial arts and becomes a saint in one's body. If you practice to the extreme, you can rival Yuanying or even a god-transforming monk. The internal strengthening method of Yi Jin is combined with the external strengthening technique of ancient Zhuang boxing, which is a martial art that cultivates both internal and external.
When the martial arts of mortals confront the immortal path of spiritual roots, which one is stronger and which one is weaker?
The spiritual roots of heaven will eventually be exhausted, and the world of martial arts will rise.
