My Ex-Girlfriends Who Traveled with Me Through the World of Cultivating Immortals

[Traditional Immortal Cultivation] + [Harem] He Chuan was devoted to his career and showed mercy and regrets in his previous life. What!

Can the perfection that was not achieved in the previous life be achieved in the world of immortality? I want them all (hands)!
