Su Chen was an ordinary delivery boy, until one rainy night, he delivered a spicy hot pot to the rooftop of an unfinished building in the city center. What was waiting there was not a hungry customer, but a woman in black who claimed to be from the "Martial Temple". She handed Su Chen a dusty copy of "Basic Breathing Techniques" and a note that read "Three days later, Qingyun Martial Arts School, or you will die if you don't come." Su Chen thought he had encountered a lunatic and threw the booklet into the car. The next day, he found that he was out of breath while delivering food and climbing the seventh floor, dodging a charging electric car as fast as a gust of wind. On the third day, three strong men covered in steam blocked the door of the Tongzilou where he rented. On the fourth day, Su Chen stood in front of the heavy jujube door of Qingyun Martial Arts School, still holding two unfinished cups of milk tea in his hand. His urban high-level martial arts life begins with taking orders overtime.
