A shabby Taoist priest encounters the overbearing and evil Prince Zhao, which involves hundreds of years of cause and effect. Every cause has its effect. How can we meet each other if we don't owe each other.
Hu Zhenqi: I really committed sins in my last life. I don't know how much debt I owe to Zhao Zichen, that little bastard.
Zhao Zichen: I must have been a good person in my previous life, otherwise how could I have met such a good master? One day I was a teacher, and the rest of my life I was... A husband?
