This story could have been really great but it suffers from a weak main leads, weak writing and lackluster execution.
The main leads had as much chemistry as two rocks, which is sad cause I really liked the main actress when she was in The Legend of Yun Xi, the main actor is just all around bad, can barely show any emotions. The monk and Xioaqing would have made better leads.
The story was redundant and weak, it had some good moments but not nearly enough to save the show, it was lucky to be short so you can power through it.
Overall, I would say watch it if you're a fan of the actors or if you're interested in the lore of it but I can't say I'd ever re-watch this.
