Taking over the world was easy enough. Create a few super soldiers and a sentient A.I. and you'll defeat any nation on Earth. The real issues come after that.  What do you do with the full efforts of a united mankind? Spread out as far as you can and make pretty things. The natives of the sol system spread out and occupied the every planet and moon. The polulation was skyrocketing under the support of new food and medicine systems. Back on Earth, the mastermind behind all this created something that was so powerful, the heavens themselves would send down a tribulation. After surviving the ordeal, he would ascend to a higher plane. Thrust onto the stage of martial world cultivators, he finds the world poor, dirty and dangerous. Magic is nice, but science had been coming along nicely. They had almost breeched the Void Wall at the edge of the solar system. The only option available to him now was to educate these warring savages and lay the groundwork for a proper industrial society.
