Steel Fortress: The Fists of the Empire Purify Spirit Cage

High Yu Xuan, an Imperial Fist officer, died in battle during the Siege of Terra. Blessed by the Emperor, his soul transmigrated to the Spirit Cage world, where he returned in a complete Astartes body with the [Legion Summoning System]. He arrived just as Mark's wilderness-hunting team set out, and launched an utterly merciless war of purification against the Mana ecosystem, armed with the Imperial Fists' iron will and overwhelming might. Faced with the barely surviving Lighthouse, he offered only a cold choice: submit to the laws of the Golden Fortress, or turn to dust alongside the xenos.
