Since ancient times, humanity has been the protagonist of this world.
Yet the world is vast. Though humans are gifted with intelligence, they are born frail and are regarded by the other races as livestock for slaughter.
To protect humanity's legacy and ensure its bloodline would never die out,
the ancestors used humanity's fortune as fuel and its bloodline as a furnace to forge battle armor for the protection of the race, laying the foundation for humanity's hidden lineage.
Moving through the darkness, the hidden lineage safeguards the lights in countless homes and protects the unbroken inheritance of humanity's bloodline.
For countless years, humanity and the other races have waged a hidden war. Humanity's fortune has been shaken again and again, and repeated crises have threatened to sever its legacy. As a result, the deeds of humanity's guardians have gradually faded into historical legend.
The Xuanhuang Battle Armor, once the guardian of humanity's legacy, was also forced into slumber, waiting for someone who could awaken it.
