Shen Xiao, the leader of the port city, was assassinated. Shen Yuyan, the only daughter, hid her grief and took over the chaotic "Nancheng Pier" with a gun - this was her father's hard work and a Shura field surrounded by hungry wolves. When she first took power, she bumped into Fu Chenzhou, who monopolized half of the city's underground business. The man held a cigarette between his fingertips, and his eyes were cold: "Little girl, territory is not defended with tears." But Shen Yuyan chose a bloody fight to let everyone see clearly: her blade was sharper than a man's gun; her ruthlessness was as ruthless as any old fox. Fu Chenzhou thought it was a new prey, but in repeated confrontations, he discovered that the handle of this "blazing blade" was actually engraved with old marks related to his youth. When the fire in the south city meets the ice in the north city, will it burn the city and seize the land, or will the edges of the blades collide, which one will be moved first?
