Liu Danyuan, the ninth prince of the Han Dynasty, was loved by his father and the emperor in the past and enjoyed great success. Once the situation suddenly changed, he was framed by the queen's party and his biological mother, Shu Fei, committed suicide unjustly. He was also secretly "executed" and his body was thrown into the wilderness.
Ten years later, the former noble prince returned from hell. He changed his name to "Yuan" and hid in the streets of Chang'an, a city full of dragons and snakes. With scars all over his body and ten years of forbearance, he vowed to bring down the enemies who framed his mother and son one by one, and pay with blood.
At the court, the prince who framed him has become a powerful prince, and the queen has become a queen mother, with overwhelming power. Liu Danyuan worked step by step, stirring up the situation in Chang'an with a non-existent identity. He devised ingenious schemes, set up puzzles, took advantage of people's hearts, provoked party strife, and sent every enemy to a dead end.
This is a lonely road of revenge, and every step is on the edge of a knife. He must walk alone in the darkness, search for the truth in the fog, and ignite the fire of revenge in despair until the entire decaying court is burned down.
