As Soon as He Became the Demon Lord, He Became Terminally Ill and Went Back in Time to Snatch the Saint First.

I, the Demon Lord, am reborn. In his mind are the scripts of all the opportunities, secret realms and powerful men in the next hundred years! While others were still working hard to learn skills from their masters, I had already rescued the future saint in advance and took away her sect's treasure. While the peerless genius is still fighting for life and death for a single skill, I have found a god-level inheritance based on my memory. In this life, I will use my omniscient and omnipotent perspective to stage a dimensionality reduction attack! Oh, by the way, those Destined Daughters who will be famous all over the world in the future are all mine now. This novel and its characters are purely fictitious.
