Desecrating the Immortals

Black-hearted, devoted Demon Lord top X cold and unfeeling Immortal Venerable bottom. Scheming, disabled disciple X aloof, pure master. A younger disciple-and-master romance. The bottom is the head of an immortal sect. The top was his disciple when he was mortal, but after being cast out of the sect, he cultivates into a Demon Lord and returns for revenge. No angst or complicated plot, just a cozy, healing, sweet little story. A fanfic of the game [On How to Build a Cultivation Sect]. Don't pay too much attention to the game. It's just an idle text-based cultivation game. The story exists to make up for the regret of the first disciple, whom the scummy author expelled from the sect. Basic worldbuilding: Cultivation levels: Qi Refining, Foundation Establishment... Unity, Tribulation Transcendence, Mahayana, Ascension. Treasures are ranked in eight grades: Heaven, Earth, Profound, Yellow, Universe, Cosmos, Vastness, and Wilderness. Theme: Don't get addicted to games. It's easy to end up with an update hiatus.
