Su Qingyuan, the legitimate daughter of the Yongning Marquis Mansion, mistakenly trusted the prince Xiao Jingheng and his concubine Su Qingrou in her previous life, and spent all her family to help the prince ascend to the throne. In the end, she ended up with her entire family being executed and she died tragically. Before she died, she realized that Prince Jing Xiao Jin, who was regarded as the "living king of hell" by the world, was the only one who truly protected her and fought for her.
Once reborn, Su Qingyuan returned to the age of fifteen - the day when the prince was betrothed.
With memories and hatred from her past life, she exposed her concubine's poisoning plot on the spot and refused to marry the prince in public, shocking the whole capital. In order to protect her family and avenge the scumbag, she took the initiative to approach Prince Jing Xiao Jin, whom she had alienated from her previous life, and made a marriage contract with him on the condition of "helping him consolidate his power".
From then on, Su Qingyuan relied on the prophets in his previous life to make progress step by step.
