Because Jiang Jiuli was absent from the growth of his son Fu Mingchu, he was suppressed by his stepmother Lin Roujia and developed a dark personality, activating the world-destroying device. In order to reverse the outcome, she used the underworld pass to return to her son's eighteenth year, and entered the aristocratic academy as a transfer student to protect him, resolve the crisis, and guide him to do good. Faced with Lin Roujia's forged DNA and public smear campaign, Jiang Jiuli teamed up with the old underworld department to expose the conspiracy in public and put him in jail. After the father and son reconciled, the recall order from the underworld arrived, and Jiang Jiuli turned into light and left. She resolutely resigned from the priesthood and entered reincarnation with her memories, hoping to renew the relationship between mother and son in the next life.
