Survive in the Doomsday Survival Game

It has nothing to do with reality, it's all made up. If you want to see something that is consistent with the facts, please avoid it. There is no rebirth, there is a golden finger, and the plot development depends on whether there is CP or not. A global disaster has befallen Blue Star, known as the doomsday world. However, at the same time as the doomsday comes, Blue Star is controlled by an unknown higher planet, requiring everyone to enter a survival game. In the game, people can survive through their own efforts and even gain powerful power, but they may also lose their lives and sink into the game. Blue Star, which was about to fall, had a chance of survival with the intervention of the survival game. Is it to gain powerful power from the survival game to change the current situation of Blue Star, or to disappear into the survival game and become one of those who barely survives, or to sink into the game and forget about oneself...
