On one day, divine beings descended from heaven all over the world in different countries of the planet, who announced the day of judgment. It was the beginning of the end of the world. Divine messengers announced that towers had appeared in every country around the world. These are survival towers. There are 100 floors in the towers and in order for the deities not to destroy the earth, people must go through all 100 floors with different monsters. It's like an RPG game. People could upgrade their levels, classes, skills, weapons, and more. Is it a real-life game? Every month, all the people of the planet automatically move to a new floor of the tower trying to survive.
