Earth Monster Concentration Camp

Monsters emerge from a strange door, and humans awaken to their power. After more than thirty years of doomsday nightmares, they awaken on the eve of the doomsday and gain the ability to control all matter. The safe base that humans need most is built in the blink of an eye. With the strengthening of abilities, human civilization recovered bit by bit. When the second door to another world opened on the earth, countless steel cities had appeared on the earth. Spaceships shuttled at an altitude of 10,000 meters to patrol the monsters on the ground. The strong men who walked out of the training room entered their world through the connection point where the monsters came to this world. The vastness of the creatures in the universe was completely unfolded on the earth.
