Honghuang: Tongtian's Son, From the Start I Became a Disciple of Taiqing

(The protagonist establishes a demon court; muddles through the Witch-Demon War and the Investiture of the Gods; in Journey to the West, he specializes in setting traps for Buddhism... Everyone powerful escapes unscathed, except Jieyin and Zhunti.) Cang Lan wakes up to find himself inside a giant egg. He binds to the Heavenly Fortune System and receives his beginner's reward, only to discover that his father is Sect Master Tongtian. He immediately berates the System: "You useless thing! Your beginner's reward isn't even as valuable as the welcome gift my family gave me." Tongtian: "My precious son has finally hatched..." Laozi: "As the son of my third brother, he should naturally inherit the Dao of the Three Pure Ones. Third Brother, how about making him my disciple?" Yuanshi: "Hey, Elder Brother beat me to it. But Lan'er should count as my disciple too." Tongtian: "Haha, sure, he can be both..." From then on, the crown prince of the Interception Sect becomes the eldest disciple of the Human Sect, and the Primordial World descends into utter chaos.
