You Cultivate as an Immortal, I Cultivate as a Demon, and We Join Forces to Dominate the World of Cultivation

(Two male protagonists + two strong men + cultivation + unlimited pull + vest + master and apprentice) Jiang Huai just took a nap and time traveled, and he still traveled to a big locust tree. Fortunately, this is a world where you can cultivate immortals, but unfortunately he can only cultivate demons. One day he fell in love at first sight with a beauty who was cultivating immortality, and finally he was able to turn into a human being. Of course he chose a man, but who knew that the beauty was also a man! The world is so malicious to me! What to do? In fact, sometimes gender doesn't need to be so rigid, what do you think? Master!
