Lanzhou Yu Emperor Feng Tianyi was forced into the palace by the Xue clan, an important minister of the imperial court, on his wedding day. Feng Tianyi was desperately sent out of Nanyu City by his guards, and strayed into the forest on the border of Nanyu City. He met Yu Huanzhen, an organ master who was living in seclusion there, and was rescued by Yu Huanzhen.
Feng Tianyi felt that he had lost everything and that his life was meaningless, so he prepared to commit suicide and die for his country.
Yu Huan really had an appointment with his master Ji Shu, so he invited Feng Tianyi to go with him to meet Ji Shu's appointment.
