During the Qi Dynasty of the Ming Dynasty, Li Zhiyuan and Jing Yuande of Huai'an City secretly discussed the White Lotus Rebellion in a tea house, and were overheard and arrested by the captain. Shang Shengzhai and other leaders tried to rescue them and bribed a substitute to rescue the two. Mi Yuanzhang and his apprentices, the "Four Tigers of Shandong Xiaoyi", were provoked by Shi Chaoran because of their fame. The two sides started fighting in Shijiawa, and Shi Chaoran gradually felt overwhelmed with one enemy and four enemies. Later, Mi Yuanzhang and Shi Chaoran resolved their misunderstanding with the mediation of Qi Laosi, and joined the White Lotus Sect together. However, Qi Laosi was assassinated by a female assassin at night, who called him a flower picker. Shi Chaoran told Mi Yuanzhang that there was something hidden behind this. It turns out that Qi Lao had behaved inappropriately when he was four years old, and the assassination may be related to this.
