Young Liu Hengshun dreams of becoming a hero, inspired by Duan Lin, the steadfast director of Jiuhe Town’s Security Department. However, his ambition is constantly hindered due to his stove disease, a rare condition that limits his physical capabilities. When the Zhongyuan Festival River Lantern Festival stirs up memories of the Baiting Mountain fire tragedy, Liu Hengshun, alongside Du Shuai and Sun Xiaochou, embarks on a daring midnight expedition to uncover the long-buried truth. Their journey leads them to Xiaobai, a mysterious saint of the Mogudao sect, who has been hiding in the ruins.
As the layers of deception unravel, Liu Hengshun realizes the fire from a decade ago was no accident. The emergence of the elusive Pipe Man, a shadowy mastermind manipulating events from behind the scenes, throws the investigation into deeper chaos. What seemed like a simple pursuit of justice turns into a web of secrets, betrayals, and hidden forces that threaten to bury the truth forever. With the lines between friend and foe blurring, Liu Hengshun must push past his limitations to expose the real culprits before history repeats itself.
