In 5 15 BC, He Lv, the son of Wu, asked Zhuan Xu to assassinate Liao in order to seize the throne. Zhuan Xu hid a dagger in a fish's stomach, took the opportunity to serve food, stabbed the prince, and himself was killed by the prince. Comet hitting the moon is a rare astronomical phenomenon, which is used to indicate that Zhuan Xu stabbed Skyquake, and also to indicate that the assassination was very rapid.
According to Records of the Historian Biography of Assassins, Yan Sui, a rich man, had a grudge against Hou Han and asked him to assassinate Han Hou. Nie Zheng broke into Han Fu alone, tried to kill Han Gu, then broke his face and committed suicide. Bai Hongguan means that Nie Zheng's actions touched the sky, which also means that his swordsmanship is as fast as electricity.
After He Lv usurped the throne, Qing Ji, the son of Wu Wangliao, fled to Weiguo. The ambassador and Lu wanted to leave to assassinate Qing Ji. He lied that he had offended the king of Wu, absconded with guilt, gained the trust of others, and stabbed him to death unexpectedly. It is said that an eagle crashed into the palace at that time, which was both a metaphor for leaving the sword and a move to touch the sky.
