My 999th Life: Omniscient Overlord

For eighteen years, Li Chengyu was the dull, academically failing son of a chaebol, the target of constant ridicule and bullying. Everyone thought he was a simpleton, but little did they know... he wasn't dull—he was just finally awakening from suppressing 999 lifetimes of apex knowledge! From immortal cultivation to interstellar tech, economic mastery to peak combat, Li Chengyu is a reborn grandmaster of everything. Now, with his mind unsealed and Foundation Building achieved, the \"idiot\" is ready to enjoy his long-deserved vacation, starting with a perfect score on the college exam and a trillion-dollar stock market play. But how long can an all-powerful being truly \"relax\" when cosmic forces stir and ancient enemies might just remember him?
