I don't know what an immortal army is!

Xianjia Army does not refer to the Mijia game or Mihayou player group, but refers to the specific player group related to Mihayou Genshin Impact game.

The Xianjia Army originated from the followers of the "Xiandi" (now banned), and they spontaneously formed because of their dissatisfaction with the environment of the rice community or other reasons. This group includes rice players, pure fun people, pure abstract people and so on. They may take anti-gang as the basic organizational form and have a strong abstraction.

Mihayou is a game company, which owns many kinds of games, such as Genshin Impact and Collapse College. Mihayou player group refers to players who like and play Mihayou games. They may get together because of their love for the game and form a larger group of players.

In a word, Xianjiajun and Mihayou player group are two different concepts and cannot be confused.
