This one gets you with the worst possible roommate situation in cultivation fiction: you wake up a thousand years in the past, and the skull you're renting belongs to the man who killed you. Lv Shaoqing never asked for the Spring and Autumn Ring, and the righteous immortal alliance never cared, they slapped "world-destroying demon" on him and ran him down for it, which tells you everything about how righteousness works in this genre. So the fights here aren't sword-versus-sword, they're a possession war fought inch by inch over control of one body, in the middle of the enemy's own house, where getting caught thinking too loud is fatal. Forty-eight episodes of ONA runtime means it actually sits in that tension instead of powering through it. If you like your xianxia protagonists winning by nerve and timing rather than raw cultivation levels, this is your poison.

After stumbling onto the immortal treasure called the Spring and Autumn Ring, the cultivator Lv Shaoqing is declared a world-destroying demon by the righteous immortal alliance and hunted until he dies. Instead of ending there, he finds himself a thousand years in the past, living in the same body as the enemy who killed him. Stuck deep inside that enemy's stronghold, he matches wits with his host to take over the body and stay alive, predicting the enemy's plans so he can gather rare treasures first. Along the way he becomes the most loathed playboy of the righteous path. As long-buried secrets of the cultivation world start to surface, he realizes that history has already shifted course. This action fantasy ONA runs for 48 episodes.
