The story takes place in the fictional dynasty Dayong, a world where rivers, lakes and temples are intertwined. Dayong established the country with force, and the imperial court established Tianshu Yuan to control the Jianghu sects. At the same time, hidden stakes were spread all over the world. When the protagonist travels to this crisis-ridden world, it is the time when the Three Kingdoms of Dayong, Beidi, and Xihu are at odds with each other. The struggle between the "Qingliu Party" and the "Xungui Sect" within the court is intensifying. There are undercurrents of forces such as the Tang Sect (a family of organ poisoners), the Medicine King Valley (a holy land of medical skills), and the Blood Knife Sect (a demon killer organization) in the rivers and lakes.
