Fortunately, as a transmigrator, Lucas also mysteriously awakened a system that allows him to evolve his summons into their mythical beast counterpart. Follow Lucas and his journey to greatness as he evolved his beasts into never been before seen mythical creatures.
Aurora Grey thought she could win her husband, Lucas Rossi's heart, even if it took years. For three long years, she endured his coldness, hoping that one day he would see her as more than just a convenient substitute. But when she reads the headlines announcing Lucas’s return to the city with his ex-girlfriend, Julia Mayhem, the truth hits her like a dagger—she never had a place in his heart. Lucas's affection had always belonged to Julia, and now that she’s back, Aurora knows her time is up. No longer willing to be the woman in the shadows, Aurora takes control of her fate. With a sharp resolve, she demands a divorce, choosing to reclaim her dignity rather than watch the man she loves cherish someone else. But Lucas Rossi isn’t a man who easily lets go of what he considers his. The moment Aurora steps out of his life, he realizes just how deeply she had entwined herself in his heart. Driven by a need to reclaim what he’s lost, Lucas tracks her down, determined to make her see that she belongs with him—and no one else.
