Only Ou Yezi's Dragon Spring Sword Art could restrain it, but it could also be restrained by the Seven Stars Art. This cultivation technique required both the upper and lower levels to cultivate. If one cultivated only one volume, the lighter the case, one would not be able to reach the highest realm. The more serious the case, one would go berserk and become neither human nor ghost.

Judging from the situation of the Black and White Impermanences who cultivated the upper and lower scrolls, the Black Impermanence had a backlash, but the White Impermanence did not. Perhaps the side effects of the male full cultivation were greater.
