I, {Lin Chen}, suffered a misfortune in the beginning when my fiancée broke off the engagement in public and became the laughing stock of the whole city. In a desperate situation, I activated the historical mission system. The system releases tasks that integrate real historical events. Upon completion, you can unlock generous rewards, improve your strength, and obtain scarce resources. Faced with the unscrupulous media who smeared me, the scheming mistress who provoked the superiors, and the yandere villain who was secretly watching, I carefully planned every step, used the power of the system to rise steadily, and slapped all those who despised me in the face. The arrogant fiancée is secretly paying attention, and gradually conquers her own fall; the system comes with highly intelligent AI, which imitates human thinking to assist in decision-making. I will eventually create my own glory in a different world that integrates real history.
