Equation originally challenged the Dungeon Dungeon of Rules in the original time and space, but during a challenge, he was attacked by an unknown creature. When he woke up, he found that he was in another time and space. Lucky people were being selected from the sky to challenge the dungeon of this time and space. The properties of the two time and space seemed to be the same, but in the original time and space, they were challengers representing their own countries. Here, it would be more appropriate to use players to describe them. In order to return to the original time and space, Equation had to start a new round of dungeon challenges.
Purpose: Challenge the dungeon with wisdom and change your destiny with your hands
