I, Who Failed to Ascend, Relied on Female Nuns to Become an Immortal?

Sheng Xiao, a peerless genius who practices the Nine-turn Xuantian Technique, opened the Heavenly Gate with his sword when he had practiced for less than a thousand years, transcended tribulations and soared, but he understood the true meaning of the technique during the thunder tribulation. If you want to ascend perfectly, you must go through nine reincarnations and rebuild. When he was dying, in order not to affect the practice of magical skills, he used the power of laws to set several restrictions on several beauties who were also at the top of the world. However, what he didn't know was that each of the beauties was better at exploiting loopholes in the rules than the last one. So, I, who originally wanted to become an immortal by relying on my own strength, actually became an immortal by relying on female cultivators?
