Dragon Flag Fluttering

In the future Blue Star, war is raging. Different countries, different races, and different religions, for their own interests, regardless of the safety of Blue Star, have used various destructive weapons in an endless stream, blasting the entire Blue Star full of holes. The sky is covered with dark clouds, there is no sunshine, and acid rain is dripping. In some places, the ground is bare; in other places, it is covered in heavy snow and ice. The entire Blue Star's ecology has suffered unprecedented destruction. The surviving people can only survive like gophers, hiding in deep underground fortresses. Blue Star is in danger. At this time of crisis, a mysterious hero emerges. Save the building from collapse, turn the tide and the crisis. Blue Star has since moved towards an era of peace, prosperity and strength in outer space colonization.
