The spiritual energy quietly revived, and the animals began to become spirits. Chen Xiao, a retired soldier and true master of Xingyiquan, hid in the market and became a courier in order to find out the truth about the death of his comrades. During the day, he shuttles between buildings, befriending a delivery cat demon who is worried about rent, and a loyal dog that works as a security guard; at night, he transforms into an urban knight, using traditional Chinese martial arts to fight against dark organizations that use goblins to do evil. When the human race extremists and the demon race radicals are at loggerheads, a war affecting the city is about to break out. Chen Xiao stood at the end of the bridge with a horizontal stick, and behind him stood his brothers - whether human or demon. "My express delivery area is guarded by my rules. Anyone who wants to destroy this balance should first ask me about the kung fu passed down by my ancestors." This is a story about protection, brothers and morality, and rekindling the soul of martial arts in the reinforced concrete jungle.
