Lu Changsheng transmigrates to the Primordial World and gives up the Grandmist Violet Qi from the start, hiding in the boundless sea to fish.
That's because he's bound to the Record of Tribulation-Evading: Evade a tribulation and gain what remains; defy fate and incur a debt to the tribulation.
During the Dragon-Han Tribulation, he saves the Qilin and rejects the Ancestral Dragon. In the battle between Dao and Demon, he awakens Hongjun with a single sentence, then turns back to cultivating formations. When a seat is reserved for him at the Purple Cloud Palace, he waves it away and stays home, yet the Primordial World spreads rumors that he's already a sea-dwelling sage.
Lu Changsheng: “Stop spreading that around. I'm only at the Qi Refining stage.”
Luohou watches the sea, the Three Teachings make their moves, and mighty beings from every heaven and world test him.
He has only one rule: I can keep a low profile, but if anyone dares touch my sea, I'll make sure they die in my formation.
