I Just Want To Game In Peace

Story:

It costs a drop of blood for one life in the game. Others waste their time playing games, whereas I waste my blood. A dimensional storm befell Earth, and dimensional realms appeared everywhere. Immortals, gods, demons, angels, elves, and many other creatures from other dimensions came to Earth. However, all the mysterious dimensional realms became dungeons in a mobile game. Other people risk their lives to venture into the realms, but I just play the game like crazy.
