I Build a Sanctuary in Warhammer

Cohen traveled to a strange and terrifying future world, where pure death was a luxury... In the dark underground metal world, the dark forces barely maintain order. In the deeper ancient giant building structures, there are countless strange and human-eating existences hidden: Bloody mutants, body-modified survivors, ancient killing machines, and warp demons who came through the rift! Cohen desperately discovered that this was actually the Warhammer world! HOLY! SHIT! Along with him traveling into this world, there is also a magical system called "Shelter". Cohen builds his own super shelter by searching for supplies in the bottom nest. Ceramic fortress, ancient technology, Astartes biological modification threads, casting blueprints... Hundreds of years later, when the Zergs are raging, subspace demons are invading reality, and the green-skinned orcs are starting a war, countless battleships loaded with super soldiers shuttle in to save the human world! "This is Coin's world, this is my Great Expedition!"
