[Hard Sci-Fi] [Soft Sci-Fi] [External Mechanical Bone Marrow Biochemical Technology] [Alien Battlefield] [High-Tech Interstellar Civilization] [Chronicle of the Future Human Struggle Against Alien Races]
In 2300 AD, Blue Star's ecosystem collapses. Humanity travels 84 light-years to establish a new home on the exoplanet NX-2291b, whose mass is greater than Earth's. The colonial star systems prosper for centuries, until the Silicon Crystal Krong, the Psionic Elda, and the Biochemical Devourers arrive one after another. To avoid extinction, humanity is forced to implant the forbidden art of “External Mechanical Bone Marrow” into their bodies. It is neither traditional powered armor nor an exoskeleton, but a biomechanical symbiote that grows from the marrow cavities. It will protect you, but it will also devour you.
Xiao Handong is the sole survivor of Kadera Three, a colonial satellite. His body has been transformed by biomechanical machinery: his left arm came from the Krong, his breastplate was carved from a tyrant-class beast, and his blade is called Ashfang. When the Ark's silver eyes light up, no one can tell whether he's human or a living weapon that crawled out of the ruins of a colony. Humanity fled Blue Star to survive. But the price of surviving on an alien world is becoming less and less human!
Extra-mechanical bone marrow technology, advanced civilization technology, and alien battlefield themes. Human alien colonists are faced with the invasion of hostile alien races, alien monsters, and alien zerg races, and they must fight to protect their new home!
