Don't Possess Me, the Righteous Path Is Running Out of People

Ji Nanbei transmigrated into a cultivation world and became the junior disciple of a declining demon sect. His master was always drunk and absent, his senior brother was being hunted by the righteous path, and his only senior sister just wanted to use his misfortunes as entertainment. Just as he was packing his bags to flee, the 'Strongest Demon Cultivator System' finally activated. The system function [Possession] unlocked, allowing him to randomly occupy others' bodies and synchronize their cultivation insights. On his first possession, a flash of light. Ji Nanbei looked at the cold and ethereal girl in the mirror, feeling the vast golden core spiritual power within her, and fell into deep thought. He seemed to have possessed the legendary righteous path's holy maiden—a prodigy who reached Qi Refining at six, Golden Core at twelve, and was unmatched among her peers. Even more absurdly, this rumored icy and aloof number one of the righteous path spoke timidly in his mind: 'Can... can you not do bad things?' From then on, the demon sect's junior disciple's style completely deviated. By day, he was a lazy demon sect disciple, bitterly cultivating. By night, he was the righteous path's prodigy, using the most supreme immortal body to practice the wildest demonic arts, while also soothing the timid 'host' inside his body.
