Why Provoke Her? An Ancient Demon Lord Dwells Within!

Su Ye transmigrates into a romance novel—as the heroine's companion bound to a Blackening Investment System. Every time the pure-hearted Luo Qinghuan succumbs to darkness, he reaps rewards. The darker she falls, the greater his gains. So Su Ye does the unthinkable: he deliberately corrupts the destined savior of the realm. When the heavens' mightiest warriors discover the sacred maiden has become a demon empress radiating sinister power, they cry out in horror. The gods descend to destroy her—until Su Ye steps forward, having invested everything in her transformation.
