My Football Group Is Full of Really Big Guys

In 2015, 17-year-old Li Kai accidentally joined a "football boss chatting group." The names of football giants such as "Alien Ronaldo", "Roberto Carlos", and "Didier Drogba" are all in the group. They will discuss some football issues and then send out some exclusive red envelopes. Li Kai originally thought they were just a group of fanatic fans of the stars... Wait, why does the red envelope say "The End of Ronaldo"?
