Blue Star was selected by the "High-Dimensional Fairy Tale Book", and copies were randomly opened around the world. Each fairy tale is an independent horror plane, following twisted logic and bloody rules. The fate of each country is bound to the tasker. If the tasker dies, the fate of the country will decline. If you clear the level, you will be rewarded with incredible resources or technological breakthroughs. All mankind witnessed "survival" through live broadcast.
