Hello y’all, I am trying to find an apocalyptic BL novel, but I don’t seem to find it. The MC had an spiritual body and was raised by the patriarch of an evil sect to kill him and absorbe his cultivation, but then he transmigrated to the body of a second generation dandy. The sister of the MC original body returned to before the apocalypse happened and since in the future it was the MC faulty that she died, she tried to kill him, but since he was a cinnamon bun he gained the heart of a Male Lead that is an officer in the army. Then the boyfriend of the sister also falls in love with him and leaves her for him. The MC then domesticates a zombie. Other Male lead is the top notch in a prison.
