Delirium, an unknown Chinese overseas student, became a sparring partner for the university football team due to the pressure of life. He thought it was just a job to make money, but he accidentally awakened to the "legendary football system". From precise passing to beastly charging, from tactician master to locker room leader, Zhen Tailin relied on the abilities given by the system and his unremitting efforts to step by step from the sparring bench to the starting lineup, and from the college arena to the professional league. He conquered his teammates, coaches and audiences with his incredible performances, broke racial prejudice, and was eventually crowned the supreme king of the rugby world.
