In the winter in Shencheng, the snow is colder than a knife. Sanda assistant Lin Feng wanted to treat his mother with his meager income, but he was targeted by Zhao Hu, the leader of Beitang Hall, because of the "old grudge" left by his father - the stall was smashed, his mother was intimidated, and even his only shelter was burned to ashes.
Desperate, Lin Feng stepped into the underworld at the urging of Lao Scar. With a "life-threatening" ferocity, he started out as a gangster collecting debts for others. With his fists and unconventional thinking, he fought his way through gang wars. He got acquainted with the clever mouse, and developed a complicated relationship with the involuntary Su Qing. On the verge of life and death, he glimpsed the truth of Shencheng's underworld: Jin Ye's balancing skills, Li San's wolf ambition, Zhao Hu's bloodthirsty nature, and the deeper conspiracy behind his father's death.
From avenging his father to protecting the people around him, from being coerced by the world to trying to rewrite the rules, Lin Feng stepped on blood and snow every step he took. When the Jinmen Gang invades on a large scale and the Yilian Gang falls apart, he must hold on to the bottom line amidst betrayal and killing, and use the "hard spirit" of a Northeastern man to roar his own dragon roar in this steel city.
