The Eternal Supreme, Li Yunxiao

Ranked third among the strongest warriors on an entire continent, Gu Feiyang is still not strong enough. His cultivation has been stuck at the Nine Heavens Martial Emperor realm for years, blocked by the very rules of the world itself. So he does what any desperate genius would do — he manipulates someone who loves him, burns through forbidden demonic energy, and kills himself to start over from scratch. He reincarnates as Li Yunxiao, a 15-year-old nobody on the Tianwu Continent, where martial strength is everything and he currently has none of it. The catch is he remembers all of it — the power, the schemes, the people he used to get here. Now he's got the mind of an emperor trapped in the body of a teenager, trying to climb back to the top while dealing with all the enemies and unfinished business from his previous life. This ONA from Dancing CG Studio adapts a web novel and leans into a pretty intricate power system that blends traditional martial arts cultivation with the reincarnation restart. The historical setting gives it real texture beyond just fight scenes. If you liked the cultivation world-building in Fighter of the Destiny or the morally grey protagonist energy of Mo Dao Zu Shi, this sits in a similar lane. It also shares DNA with Congqian Youzuo Lingjianshan in how it handles an overpowered character navigating a system they already understand. The vibe is action-heavy but character-driven underneath — there's enough scheming and relationship tension to keep things interesting between the fights.
