What Do You Mean, Cold and Aloof Fairy? Give Me Some Sweetness!

My name is Li Changye. I transmigrated here and eventually joined a demonic sect, painstakingly cultivating my way to the position of elder. But then I was framed by a despicable villain. In the end, I escaped with an unparalleled secret technique for dual cultivation, which accidentally sent my body back to childhood.

Though I'm small again and all my cultivation has vanished, I still have that peerless secret technique. Give me a little time, and I'll return to my peak, strike out in the name of revenge, and become the supreme ruler of the demonic path! But first, I have to survive... Oh? A fairy says she wants to adopt me? Whoa! And she's from a sacred sect, the leader of the righteous path! I'm in! Heh heh heh, watch me turn the sacred sect upside down!

...Years later, the demonic path has been wiped out, the righteous path rules supreme, and the sacred sect has been elevated to the status of the Supreme Immortal Sect.
