Reborn as the Villain, I Marry the Protagonist's Fiancée from the Start

Transmigrated as the young master of the demonic path, he’s supposed to be publicly rejected by the chosen son of destiny, Xiao Mofan, right from the start? No, this isn’t how the story’s supposed to go! Ye Xiao instead pulls his shocked fiancée into his arms and announces their wedding on the spot, activating the [Destined Villain System]! Every time he snatches an opportunity from the chosen son of destiny, he gets a hundredfold return! From that moment on, everything changes. He steals the protagonist’s “Azure Lotus Earthheart Flame”? The System rewards him with the “Red Lotus Karmic Flame,” which incinerates all things! He tames the protagonist’s future “Guardian Divine Beast”? The System rewards him with the offspring of the “Four Primordial Great Fiends”! The cultivation techniques, magical treasures, and spirit medicines the chosen son of destiny works so hard to find... Sorry, they’re all mine now! From then on, the so-called chosen son of destiny is reduced to a “treasure-hunting rat” working for Ye Xiao. Wherever he goes, Ye Xiao follows, snatching everything in sight! The protagonist’s confidantes are won over by Ye Xiao’s imperial tactics and become the most loyal guards of the Demon Empress! His loyal brothers are impressed by Ye Xiao’s iron-fisted methods and become the vanguard in his war against the righteous sects! By the time Xiao Mofan’s Dao heart is shattered and he becomes an outcast of heaven, Ye Xiao has already led an army of hundreds of millions of demons, trampling the old world’s order beneath his feet. “Destiny? Hah. It’s nothing but a stepping stone on my way to the top!”
