Why should Fei Xuan thank the bleak?

The reason why Fei Xuan thanked Bleak was that Bleak saved Fei Xuan. In the film and television drama Song of a Boy, Fei Xuan paid the price of her life for the mission of watching her fate, but she didn't let Fei Xuan interpret divination, which saved her life. "The Boy's Song" is an antique network cartoon produced by China Film every year and co-produced with Bi Li. This work is adapted from Zhou Munan's original novel of the same name and tells the story of four young chivalrous men with strange life experiences and heroism.
