A top hacker was chosen by the Lord God to be reborn into countless worlds, always as an expendable villain.

With no free will, every world became a dead end. Every one of his lives ended tragically.

He expected her to be obedient and submissive, not to resist or show emotions—a perfect pawn in his plan for vengeance.However, when his gaze locked onto the third daughter of the Lancaster family, the one who barged into the living room was her—disheveled and stained with blood. She seemed ordinary, but beneath the surface, she hid an unknown sharpness.“Do you love me?” he asked coldly.“You're crazy!” she rolled her eyes in disdain.In that moment, he smiled with satisfaction, believing he had everything under control.But she fought back. Marrying him was merely one step in her own plan.Four years later, with the Lancaster family completely destroyed, she threw the divorce papers in his face, smiling like the final victor:“Albert Wilson, have you finished using me? Thank you for making me think I once loved you. Now, never see me again, even in death.”Just as she turned to leave in triumph, she accidentally walked into a gang's arms deal, and an explosion forever separated her from him.It was only when he found the two-month pregnancy test result among her belongings that he realized he had lost the only salvation of his life.
