Ten years ago, in order to control the government and seek peace abroad, the current prime minister conspired with an assassin organization to kill the current general. The general's daughter, Qing Tian, witnessed her father's murder and coincidentally learned that the prime minister who adopted her was, in fact, the mastermind behind her father's assassination. One of the assassins who carried out the killing, known as Shadow, had assumed the name Wei Ping and was serving as the head of the guards in the prime minister's mansion. Qing Tian devised a plan to lure the assassin organization into killing her, with the real target being everyone connected to her father's death. The prime minister, the fugitive guard Li Dong, and even the assassin leader An all died under Qing Tian's scheme. In the end, when faced with Wei Ping's retaliation, Qing Tian learned that Wei Ping had deliberately shown hesitation during the assassination attempt to avoid killing the general, which led to him being expelled from the assassin alliance. Consumed by hatred, Qing Tian's plan ultimately unraveled, and only Wei Ping, who steadfastly held onto his beliefs, survived.
