Infinite Flow: The Vicious Cannon Fodder Kisses the Saintly Heartthrob

[Dual male leads + infinite-flow + shou's point of view + equally matched powerhouses + multiple personalities + mutual salvation? + devoted to each other + happy ending + power fantasy + sweet romance] [Vicious, unhinged, scheming beauty shou + saintly, universally adored/black-lotus, dark and unhinged gong (mostly the saintly, universally adored personality at first, with random switches later)] [Butterfly effect: The instances the shou experiences are all different from those in his previous life.] In his previous life, Xu Jin was killed when Pei Yi and the others sacrificed him to resurrect the dead Yu Gui. After being reborn, Xu Jin hates Pei Yi and the others to the bone. Xu Jin is consumed by the desire to grow stronger, then make Pei Yi and the others weep in despair and beg for mercy on their knees before sending them to hell. Just as he draws closer and closer to his goal, Yu Gui becomes the biggest variable. In his previous life, Xu Jin never interacted with Yu Gui. He had only heard of him: a powerful but saintly player. At the time, Xu Jin had dismissed it as nonsense. How could a player who survived the instances possibly be a saint? Xu Jin isn't one to reason things out. Whether Yu Gui is really a saint, or knew anything about the sacrifice in his previous life, he doesn't care. He hates Yu Gui with all his heart now. In this life, the two inevitably spend a long time together, and Xu Jin discovers that the man really is a saint. They clash constantly. Xu Jin hates Yu Gui, because whenever he sees him, he remembers how he was killed like a stray dog in his previous life because of Yu Gui's death. Yu Gui, meanwhile, believes Xu Jin is crooked in character, but not beyond redemption, and keeps trying to set him straight. Xu Jin's desire to kill him grows stronger by the day. At last, he finds his chance.
