In the future world, the game "Crossfire" can already allow players to enter the game world in person. Even if they "die", they can immediately return to reality. All this is because of an energy source - Ekel Ore, which is used for game operations and big data processing. However, a highly intelligent alien creature has taken a fancy to this kind of mineral from the earth, and reached an agreement with the earth. It creates game monsters first, and then allows players to attack. If all players fail, the Ekel Ore will belong to this creature, otherwise the planet of this alien creature will explode.
