"The Delivery Guy's Counterattack of the Sword God": The delivery boy Lu Chuan accidentally activated the "Sword God System" and started a ridiculous urban martial arts legend. The system allowed him to master swordsmanship instantly, and also forced him to recruit apprentices and compete in martial arts, in order to revive the swordsmanship in the modern era. Lu Chuan successively accepted apprentices such as genius girls, rich second generations, and retired special forces soldiers. Under Lu Chuan's guidance, their swordsmanship improved greatly, and they jointly faced challenges in the martial arts world. From martial arts schools to competitions, from black boxing to killer organizations, Lu Chuan used his sword to prove his strength. As his strength increased, Lu Chuan discovered that there was a bigger secret hidden behind the system: why was he chosen? What is the "Kendo Revival"? In pursuing the truth, he faced powerful enemies and inner choices. This is a story about growth, responsibility and inheritance, the collision of traditional martial arts and modern life, the integration of ordinary little people and extraordinary systems, including passionate martial arts competitions, funny daily routines, and profound thoughts.
