Five years ago, he was an abandoned son of the Li family in Jiangcheng. He was expelled from his home for "collaborating with the enemy" and became a street gangster who could be bullied by everyone. Five years later, he changed his name to "Lone Wolf" and returned with honor from the border battlefield of blood and fire, holding in his hands the power and secrets that could subvert Jiangcheng. Faced with a family that has long since changed, enemies who are eyeing him, and an old love who reunites unexpectedly, Li Zhongyi loses his youth and tears apart the veil of hypocrisy in the city with his iron-blooded skills. He roamed the business world, made plans in the dark, used loyalty as a blade and strength as a shield. While washing away the grievances of the past, he trampled all enemies under his feet. Finally, he built his own business empire and underground order in Jiangcheng, becoming an urban dragon that no one dared to mess with.
