In AD 3088, human civilization came to an end in the world war that was called the Armageddon War in later legends.
The sky is covered with dust, the sea is filled with toxins, and the earth is covered with mutated barbarism.
The surviving humans have sealed themselves in the underground city, lingering and struggling to support themselves for tens of thousands of years.
Humans, who were on the verge of extinction, sent out the last exploration team, only to find that without the knowledge of the humans, the earth had already gone through great changes and there were thousands of races.
