The Legend of Baiyun’s Apotheosis

【Mortal-style cultivation + slow-burn progression + no System + one female lead + factions plotting against one another + no mindless power fantasy】Yun Qi, a transmigrator from Earth, arrives in another world of cultivation. The Immortal Realm has collapsed, and a great calamity is about to begin. Every faction faces upheaval on a scale unseen in ten thousand years: the schemes of an immortal who once governed reincarnation, the Eastern Sea demon race's plan for revival, and the conflict between the righteous and unorthodox factions. Watch as Yun Qi rises to the pinnacle amid the machinations of these forces... Note: The protagonist has deep ties with several women, but only ends up with the female lead.
