Reborn as a Legitimate Daughter: Top Agent Starts a Dynasty

[Alternate History] Modern agent Su Qingyuan suffered a huge explosion and his soul penetrated the body of the legitimate daughter of the Duke of Zhenguo of the Dayao Dynasty. The original owner's spiritual veins were sealed with poison by his concubine, turning him into a "waste". Ji Yanyan was further framed by his concubine and his fiancé for having an affair, and died out of hatred. Su Qingyuan was reborn with her memories, killed her on the spot and slapped him in the face, unlocked the seal and awakened her chaotic spiritual veins. From winning the championship with the sect, rescuing his father at court, retreating from the enemy at the border, forming an anti-demon alliance, and then joining forces with the hidden royal family Ye Xuanyuan to kill the demon god, the former laughing stock counterattacked step by step, and finally became the goddess of war who protects the human world. All those who have insulted the original owner will pay with their blood!
