The end of the world is coming, and countries are in crisis. In order to cope with the crisis, Country X set up seven emergency bases. The outside of the base is filled with zombies, nuclear beasts, and robots that have escaped human control. They are constantly eating away at the humans outside the base. What's even more frightening is that the seven bases are also in crumbling condition, and the last home of mankind is about to be destroyed. Young geniuses, like the North Star before dawn, shine brightly and bring the last hope to mankind.

An orphan abandoned by a wealthy family accidentally obtained the system and began a life of awesomeness.
