Pseudo multiple wear revenge.
On the surface, it is a fake story. After being cannon fodder by the protagonist of his own world, the story of the favored man of heaven makes a deal with the devil for revenge and replaces the cannon fodder of other worlds to fight evil. In fact, it is the story of two bastards who are destined to fall in love and kill each other through reincarnation - Fei Shuangwen.
The open thread is a quick thread (but it is estimated to be threaded very slowly and will not be crossed too many times), and the dark thread is the emotional thread.
Point of difference: The protagonist is female when she meets the devil... Because her gender is uncertain when she travels through various worlds. In the end, it may be 1V1 or no CP, the protagonist is the attacker... And the sufferer is essentially the same person's past and present lives.
Protagonist: Wen Qingle (yue) × Wen Qingli
