The spiritual energy is revived and the city is undercurrent. Delivery boy Zhang Fan realized the true meaning of Chinese martial arts against monsters from the old boxing skills left behind by his grandfather. During the day, he walked through the streets and alleys, taking out food and serving fireworks; at night, he transformed into a hidden descendant, guarding the peace of the city with a pair of iron fists. When the ancient martial arts family despised his humble background, and when the Super Academy questioned the tradition, Zhang Fan just silently delivered the last order, turned around and smashed the head of the giant beast that attacked the city with a punch. "Delivering food is life. Teaching martial arts is our mission. The lights of these thousands of homes are guarded by ordinary people like me." Let's see how the strongest food delivery man can rekindle the soul of Chinese martial arts in the age of spiritual energy and write unparalleled legends for ordinary people.
