Try Not to Destroy My World

He died, met a goddess, and spun the wheel of fate. Instead of a clean reincarnation, he landed on the one result she clearly hated: Regressor. Now he keeps being reborn into the same world with every memory intact. In one life, he changed too much too fast and was murdered for it.In another, he tried to act normal and died anyway.In a third, he learned everything, trusted no one, and lived long enough to watch the world burn. On his fourth life, he finally understands the real problem. The Demon King’s invasion is not fixed.The stronger and more visible he becomes, the sooner the end begins. So this time, he has to do the impossible: build power without drawing attention, survive court politics without looking dangerous, and prepare a broken world for a war that will come the moment the north notices him. He has knowledge from multiple lifetimes.He has no manual, no safety net, and no guarantee of a fifth try. The goddess only gave him one instruction: Try not to destroy her world.
