I'm so glad that this spin off was created after The Untamed. This movie allows us to take a deeper dive into Nie Huaisang, which we didn't get in The Untamed. Huaisang is a smart, clever, selfless, and kind person. He only wants to live freely, doing the things he's passionate about while his brother Nie Mingjue is master. Unlike Huaisang, Mingjue excels at martial arts and so the two brothers often butt heads. In this movie the two set off with disciples of the Nie Clan to seal the sword spirit in the family tomb that has gone array. The journey is not an easy one and both brothers face many obstacles. It's through these obstacles, you get to see how strong their relationship is and that both are willing to sacrifice so much for each other. There's more love there than one would have imagined just from watching The Untamed. This movie really allowed me to love these characters even more, and I won't lie, I cried a couple times. Their relationship is a beautiful one and I'm glad to know Huaisang much later on got his revenge for his brother's death.
