Dachuan, who has been a military fan since childhood, has always dreamed of becoming a marine, and at worst, an armed special police officer to catch drug lords. But because of his mistake, he became a fireman. Dachuan is simple and persistent, full of curiosity, but he often makes some low-level mistakes when he is in a daze. However, Dachuan at the scene of the fire has an unusual potential to save people. Relying on his inexplicable intuition and reckless courage, he overcame countless difficulties and saved dying people in countless unexpected places and times. Reckless Dachuan often goes his own way and is not bound by rules and orders, but he didn't know the value of the team until he really paid a huge price. ...

Shi Peng

A recruit who trained with Dachuan. Unlike Dachuan, Shi Peng was saved by a fireman when he was six years old, so he dreamed of becoming an ordinary fireman since he was a child. He is an avid fire fan. When he was at school, his greatest hobby was watching the fire brigade on the street corner. (Later, I was assigned to this squadron with Dachuan. ) Shi Peng's personality is rigorous and stubborn, and he regards fire control as extremely sacred. He speaks with a set of theories and rules he has mastered, and it is his dream to become a radiant hero. Shi Peng has always looked down on Dachuan, thinking that a bumpkin who knows nothing like him is not worthy to be a fireman. The two men have been at odds since they were recruited. ...

Li Mingliang

The oldest noncommissioned officer of Ping 'an Squadron, the acting squad leader, and the direct leaders of Long Dachuan and Shi Peng. Brett is a natural optimist, lively and active, with a strange idea on his forehead. In his eyes, Dachuan and Shi Peng are as stupid as wood and as stubborn as stone. Nothing is more interesting than teasing these two people. The squad leader Li, who seems to have set himself on fire, is completely different. He is accurate and quick-witted, planning the distribution of fire points and the control of fire control facilities, and almost never makes mistakes. In his mind, fire is heartless, but people are affectionate. Leaving more happiness to the comrades around him will make him happier than leaving it to himself.

Zhou Yu

The squadron leader of Ping 'an squadron, an old fireman with more than ten years of fire fighting experience. Captain Zhou is usually unsmiling, strict and overbearing, and even often ruthless. When Long Dachuan and Shi Peng first entered the squadron, they could hardly adapt. But after getting along for a long time, two people realized that Zhou Team is a hard-spoken, hard-hearted, strong, kind and true spiritual leader.

Liu Haiyang: The deputy squadron leader, the frontline commander of general disasters, is the "living map" of the squadron. Compared with Zhou's team, it is much gentler and likes to mingle with the soldiers. But Liu owes his family a lot. He is a competent fireman, but he will never be a competent husband and father.

Huo Lingling

120 nursing staff in emergency center. Hot temper, a stubborn girl who never gives up. Lingling and Dachuan are middle school classmates.
