Worker in the Wasteland World

From that day on, the flame of human civilization was extinguished, and the long night fell. From that day on, the embers of human civilization still exist, and there is still glory on the other side. Due to an unknown crisis, the technological civilization that had evolved to the interstellar era was deprived of it, and human beings continued to lose their territory of survival until they retreated into the fortress. The fortress is defended by a gray and dead wasteland, strange beasts that seek to devour people, and an undercurrent of crisis. On top of the ruins, there are still people who stubbornly build the Tower of Babel that reaches the sky, eager to climb the steps to pay homage to God and gain new life.
