Perfect World: the Highest Road

This is a story about a world where Gojo Satoru was tired of spells and wanted to find a stronger place. He instilled the knowledge of time and space into Su Nuo, and thereby reincarnated into the lower realm of the perfect world, where he competed in the sky and climbed to the highest level. (It can be regarded as a fanfic of Gojo Satoru and Perfect World, including female transformation, which is a semi-cool story)
