In 227 BC, the Qin army moved its troops to change the river. Prince Dan of Yan made a desperate move and planned to assassinate Qin to death.
The rumored "world's best assassin" Jing Ke was just a futile exile who lost the meaning of his life and was forced to pay for his life; the "righteous man" Fan Yuqi who died generously was a sacrifice who was forced to sacrifice his head under the weight of lies and righteousness. In this expensive gamble full of pig iron, poison and power, the men of the Warring States Period were rushing to hit the cold war machine of Great Qin. Only Wei Su, a Mo family secret agent who possesses Yue Nu's swordsmanship, watched this ridiculous carnival coldly with extremely sober eyes. She saw through the hypocrisy and cruelty behind "a scholar dies for his bosom friend" and refused to be buried with him.
