In the year 2135 by Blue Star reckoning, human industrial civilization reaches its pinnacle. Decades of accumulated industrial might give rise to the first deep-space fleet.
In search of the secrets of the universe, richer resources, and new homes where they can settle, humanity breaks free of the solar system and sets out for the vast sea of stars, beginning its exploration at the edge of the Canis Major Dwarf Galaxy.
The interstellar civilization of the Canis Major Dwarf Galaxy considers the Blue Star deep-space fleet's reckless exploration an act of unwarranted intrusion.
Without diplomatic negotiations or a warning of war, two standard-issue fleets cross the sea of stars and annihilate humanity's entire deep-space fleet with their overwhelming technological superiority.
When the smoke clears, the alien forces analyze the wreckage of the fleet, follow the shattered data trail, and pinpoint the blue planet in the solar system.
Dozens of deep-space warships hidden among the stars silently approach the outskirts of the solar system. Using advanced technology beyond human comprehension, they disable every nuclear weapon on Earth, send the satellites in the sky crashing down, and sever all ground radar, scanning beams, and communications networks.
A colossal interstellar fortress hangs in geosynchronous orbit above Earth. From then on, Earth is reduced to a prison.
In the depths of the apocalypse, the genius boy Lu Chen continuously upgrades his mecha, breaks through the alien blockade, and leads the surviving humans in a desperate counterattack, step by step, to defend their home.
