"Long Night Gale" is set in Jincheng, a city with flashing neon lights but turbulent undercurrents. It tells the story of Shen Che, the young master of "Lietang", who struggles between loyalty and betrayal, darkness and twilight in the bloody whirlpool of alternating power. Shen Che was adopted by Shen Xiao, the leader of the "Fierce Hall" since he was a child, and was responsible for the mission of protecting the organization. However, during an operation against the hostile force "Youth Federation", he discovered that Shen Xiao was closely related to the truth about the destruction of his family. On one side is the grace of upbringing and the bond of brothers who have gone through life and death, on the other side is the concealed family blood feud and guilt for innocent people. Shen Che tears apart the layers of disguise amidst the light and shadow of swords, trying to rebuild order in the collapsed faith. When the "Youth Federation" presses harder, internal elders have their own agendas, and mysterious third-party forces disrupt things one after another, he must hold on to the knife and guard his heart in the long night - should he become a new tyrant, or open a bloody road to dawn?
