Tv series, right? The drama mainly tells the story of the gratitude and resentment between the master and apprentice, brothers and sisters of the northern Wulin Sect "Swallow Gate" from the 1920s to 1950s. Combined with the historical vicissitudes of warlord melee, War of Resistance against Japanese Aggression and civil war, it shows the life track and growth process of Yan Zimen's three outstanding disciples with different beliefs and pursuits. This drama promotes China Wushu, with its internal strength and lightness skill. It is a rare good film with educational significance and more entertainment and appreciation. The most breakthrough highlight of this drama is that the real protagonist of the story is actually the villain Li Yunlong. In general TV series and movies, the protagonist will never take the negative side as the story, at least he will turn over a new leaf. However, Li Yunlong, the protagonist of the story, has gradually fallen from a fledgling cynicism to perdition, which is thought-provoking. According to the ranking of the cast, Li Yunfei's positive image should be the protagonist. However, this character is very thin, which is nothing compared with Li Yunlong's plump portrayal. I don't know if it was the director's intention or the shooting error. But in any case, this is the most breakthrough highlight of this drama, and it is a thought-provoking framework preparation for this drama.
