Qin Feng, the soldier king of the century, was tired of killing on the battlefield. In order to fulfill his promise to his comrades who sacrificed their lives, he retired and hid in the Lanhai City Fire Brigade under the pseudonym "A Feng". He was willing to be an ordinary firefighter who was despised by everyone. The once-in-a-century Typhoon Poseidon struck, with strong winds tearing off roofs and huge waves hitting the embankment. The sea embankment was in danger of bursting and was about to burst and flood 100,000 people in the old city. At the critical moment, Qin Feng no longer hid, carried hundreds of kilograms of steel bars with his bare hands to seal the leaks, rappelled to the extreme in the strong wind to rescue a family of three trapped on the top floor, and held his breath underwater for half an hour to drag out the wrecked fishing boat. During the rescue operation, he accidentally discovered traces of military explosives left in the cracks of the dike, and was shocked to realize that this "natural disaster" was actually a conspiracy of overseas spy organizations. They used the typhoon to cover up the dike and attempted to sneak into the submarine base to steal secrets. While leading his team members to race against the typhoon to evacuate the people, Qin Feng fought against the spy organization alone, using the fighting skills and blasting knowledge of the special forces to resolve crises one after another. In the end, in order to protect the students trapped in the school bus and the military secrets that were about to be exposed, he detonated the remaining explosives to seal the breach. At the moment when the huge waves swallowed him, the Medal of the Soldier King on his chest fell off.
