Reborn as the Demon Cult's Young Master, but I Failed to Lie Flat

[Dual male leads + wuxia + revenge + a male lead who's wild and unhinged at first, then takes on an immortal's air, paired with a timid, submissive love interest who later rises up and turns dark] (1) Song Xi: I'm not looking for much in life. I just want to lie flat. Jiang Mudi replied with a gentle smile: We want the same thing. one hour later… Song Xi: Jiang Mudi, you bastard! When I said I wanted to lie flat, I didn't mean the two of us lying naked on a bed! (2) Later, Song Xi became the supreme leader of the martial world with the help of two moves. First move: Jiang Mudi, get him! Second move: Jiang Mudi, save me.
