Su Qingyuan, the legitimate daughter of the Zhenguo General Mansion, mistrusted others in her previous life. She was treated as a pawn by her stepmother Liu Yuru, her father Su Hongyuan, and her concubine Su Yurou. She was forced to celebrate the death of the crown prince due to illness. She was eventually killed without even being able to save her body. At the same time, her most respected second uncle Su Jingyuan was also plotted by Liu Yuru and Su Hongyuan to fake his death in battle and embezzle the military power and family property of the Hou Mansion. Once reborn, Su Qingyuan returned to the time when the tragedy had not occurred. All innocence had faded from her eyes, leaving only determination and sharpness. Pretending to be cowardly, she lurked in the general's mansion, secretly contacted her second uncle who was hiding, and collected evidence of Liu Yuru and others' crimes, waiting for an opportunity to take revenge. By chance, she discovered that Prince Xiao Che did not die of illness, but was secretly imprisoned, poisoned and murdered by relatives of the Liu family. In order to protect their second uncle, avenge their blood, and break their fate, Su Qingyuan and Su Jingyuan joined forces and waited for an opportunity to contact the prince and form an alliance. They gradually disintegrated Liu Yuru's conspiracy, exposed Su Hongyuan's cowardice and betrayal, and took back everything that belonged to him and the Su family. From an abandoned girl who was bullied by others, to a strong man who strategized revenge, and then to an empress who dominated the harem, Su Qingyuan used blood and tears as a blade to change her fate against the will of heaven, and was reborn in Nirvana. She finally became her own backer, protected the people she loved, and took charge of her own glory.
