Nine Radiance Reversing the Sky

After a parting at the vast sea, his immortal bones shattered and his soul scattered. Reincarnated on the Blue Star, the former Immortal Venerable Muge awakens his memories. In his past life, he cared for all beings but was betrayed by the gods, schemed against by the Demon Lord, and betrayed by his Dao companion. In this life, he abandons foolish kindness, acts decisively, and never tolerates injustice. The city hides dragons, secret realms vie for supremacy, he crosses the star sea, and crushes all heavens. Every being that wronged, schemed against, or betrayed him, he will visit one by one to settle accounts. — Description from novelcodex.org
