The entire class crosses over to cultivate immortality for five hundred years, carrying Golden Core and Nascent Soul cultivation bases to return to Blue Star wanting to dominate the present world, except for the "transparent person" Liu Di who claims to be a rogue cultivator at Foundation Establishment. Little do they know he is already at the peak of the Demon Emperor! Due to investigating a parasitic mortal enemy, Liu Di keeps a low profile and lurks, but successively encounters contempt from classmates and clamor from external enemies. He flattens overseas demon dens, subdues ancient divine palaces, crosses the sea to deter external powers, casually pulls out hidden ancient monsters, and even boasts wildly to feedback global cultivation of immortality, crushing everything with absolute hegemony to reach the summit as a modern deity!
