The Regressed Archmage Builds a Civilization (OP MC, LitRPG)

Kieran Ashvale is the only human who ever reached Tier 9—and he witnessed his species go extinct. Humanity's greatest Archmage never died. He only returned to ensure his species would never again need a savior. For three hundred years, Kieran climbed the Tower alone after humanity ended. Cities burned. Sanctuaries collapsed. Ancient races hunted the last humans like obsolete artifacts. He mapped every System trap, every Class designed to fail, every Pact that destroyed from within. He was strong enough to survive until Floor 273—yet individual strength was never enough to save a species that had lost its critical mass on Floor 134. Then he awoke in a pre-Tower world—with three centuries of experience intact in his mind. The System had not yet descended. Classes had not yet bound human potential. The world was fragile, primitive, and open to those who knew what was coming. Kieran had one chance to do what should have been done from the start: build humanity to compete, not merely survive. This time, Kieran will not wait for the System. He will teach pure magic before it is frozen into Classes. Build Hybrids who fight while casting. Create Enchanters who understand logistics, and Battle Mages who don't need a backline. He knows which Bloodlines give birth to high-Tier potential, which builds survive contested Floors, and which early choices create permanent limits. When the Tower finally appears, the ancient races will expect scattered, easy prey. What they will face is a war-ready civilization—built by an Archmage who has witnessed the end of everything. A civilization fully prepared. Zero tolerance for the Tower's eradication games. And this time, humanity is not the prey.
