In the last years of Yuanhe, the Tang Dynasty was in full decline, with feudal vassals and towns being divided and eunuchs monopolizing power. Qin Yinshu, the son of the Eastern Zhejiang Observer, was massacred overnight. He was the only one who was adopted by the Jianghu assassin organization "Ye Crying Tower" and developed a unique assassination technique. Ten years later, he changed his name to "Han Chan" and sneaked into Chang'an as a luthier, targeting the eunuch Tutu Chengcui, the lieutenant of the Shence Army. However, his assassination failed and he was captured by Pei Yanzhi, the commander of the Forbidden Army. Pei Yanzhi did not kill him, but handed him a secret scroll: "You have more than one enemy." When Qin Yinshu thought he was using Pei Yanzhi for revenge, he discovered that Pei Yanzhi's bottomless eyes hid a secret deeper than him. This is a game that begins with utilization and ends with sincerity. It is also a chess game in which the entire Tang Dynasty is the bet. When the truth was revealed, Qin Yinshu discovered that the person he wanted to assassinate was never a person, but a cannibal dynasty.
