In the near future, the national competitive project "Extreme Card Arena" will replace traditional e-sports. The competition will be held in a real stadium. Players will use somatosensory operations and card construction to complete offense and defense, running positions, confrontation and tactical chains. It will be a live broadcast of online games, competitive leagues and sports viewing. The protagonist was once a well-known "underworld routine" anchor on the Internet. Because his playing style was too cheap, his words were too bad, and he made countless opponents cry, he was dubbed a "professional villain" by the audience. After a live broadcast accident, he was forcibly signed by a club on the verge of relegation, asking him to lead a group of troubled teenagers into the top league. But he soon discovered that there were people in the league using "legendary cards" to manipulate the game environment, and the reason why he was banned was not just because of his bad mouth.
