In 2333, Mercury's resources are about to be exhausted. In order to avoid the resource crisis, humans have to explore other galaxies.
Some strange meteorites were brought back to Mercury. The strange energy emitted by the meteorites unknowingly changed the composition of the air. A large number of Mercury creatures mutated and launched attacks on humans.
The meteorite that was brought back grew into a beast's nest, and a large number of alien beasts rushed out of the meteorite. Human society instantly lost control, and the three parties launched a long-term war.
Although humans also found ways to become stronger, they persisted for seven years and were finally defeated under the attack of alien beasts and mutant creatures from Mercury.
In order to survive, humans left the land, and a small number of people moved to temporary huge flying objects. Here, humans continued to resist foreign invasion.
The air bases that are still flying are also named "Lighthouse"! It means the last hope of mankind.
