Qi Chen, codenamed Lone Blade, was once the chief instructor of China's top special forces team Dragon Blade. He joined the army at the age of sixteen and took charge of the Dragon Blade field operation at the age of twenty-one. In eight years, he traveled to desperate situations abroad and carried out forty-seven high-risk missions without ever losing. He was the feared king of individual soldiers on the road. Three years ago, during a joint mission to suppress drug lords and overseas mercenaries outside the country, twelve comrades in the team died heroically to protect him from completing the core goal. Qichen was fatally injured. He was lucky enough to survive, but was entangled with endless guilt and post-war trauma. He voluntarily submitted a retirement report and disappeared. He lost all his military glory and sharpness, and returned to his hometown of Jiangzhou, where he had been away for fifteen years, with the only yellowed childhood photo in his arms, just to find his biological sister Qi Yue, who was separated due to family changes when he was five years old. He originally wanted to hide in the city and spend the rest of his life as an ordinary person, suppressing the killing and cruelty in his bones. However, Jiangzhou's underground forces are intricately entangled, and street bullying and evil forces oppressing the people are frequent. His deliberately restrained edge was eventually broken by malicious intentions time and time again. What he never expected was that the man behind the sacrifice of his comrades was inextricably linked to the "Dark Pavilion", a secretly rising underground force in Jiangzhou. The road to find a girl, a bloody feud, and a stable market all tied up the returning soldier king. He didn't want to hold the sword anymore, but the world forced him to unsheath it again. Ordinary life was completely shattered, and an urban storm belonging to a solitary blade had just begun.
