Emberfang

[Hard science fiction + soft science fiction + external mechanical bone marrow biochemical technology + alien race battlefield + interstellar high technology + future story of the struggle between humans and alien races] In 2300 AD, the Blue Star ecosystem collapsed. Humanity spans 84 light-years and establishes a new home on the exoplanet NX-2291b, which is more massive than the Earth. For hundreds of years, the colonial star field prospered until the Silicium Kraang, the psychic Elda and the biochemical Devourer arrived one after another. In order to avoid being exterminated, humans were forced to implant the forbidden technique "external mechanical bone marrow" into their bodies. It was not a traditional powered armor or an exoskeleton, but a biochemical-mechanical symbiote growing out of the bone marrow cavity. It will protect you and it will eat you. Xiao Handong is the only survivor of the Kadra III colonial satellite. His body has been transformed by biochemical machinery. His left arm is from Kerang, his breastplate is cut out from a tyrant-level beast, and his sword is called Ember Fang. When Ark's silver eyes lit up, no one could tell whether he was a human or a living weapon crawling out of the ruins of the colonial star. Humans fled Blue Star in order to survive. But the price of surviving on an alien planet is becoming less and less human!
