In the vast and mysterious cosmos, only metal and bloodshed form the eternal backdrop. When Lei Yaotian—a man from our world—unexpectedly awakens on a remote planetary outpost, he is thrust into a brutal conflict against terrifying alien creatures. With no understanding of his surroundings and no way back, he must quickly adapt to survive. Under the command of the battle-hardened Sergeant Kalon, Lei—now nicknamed "Fatty Lei"—is forced to join the fray. Equipped with a heavy plasma rifle and surrounded by soldiers of the Divine Glory Empire, he faces a horde of relentless, insect-like monsters threatening to overrun the metal fortress. But this is only the beginning. From a confused and clumsy outsider, Lei Yaotian's journey unfolds into one of unprecedented growth and influence. Behind him one day will stretch an armada of massive warships, blotting out the stars—and he will smile, knowing he too has become a legend.
