Douluo Dalu: Demon God of Desire

This is a butterfly effect. After transmigrating into Douluo, Chen Yuan's Martial Soul fed on the desires of all living beings. But the prey its instincts craved most was Xiao Wu. He fought with all his might to keep hold of himself, refusing to give in to his instincts, all to protect those he cared about. All because the pebble he had cast into the pond had set ripples spreading through Douluo Dalu, completely diverting its fate. Spirit Hall watched from the shadows, the original characters' timeline fell into chaos, and the story was rewritten with a thunderous crash. Yu Xiaogang helped conceal the truth, Flender arrived, and Shrek was hastily founded ahead of schedule. Chen Yuan decided that instead of being swept passively into the undercurrents, he would take the initiative, enter the game, and go from pawn to player, personally disrupting the fate that had once seemed set in stone. [Note: A serious character-driven story, guided by logic, with no mindless power-fantasy speedrun.]
