In Warhammer, I Just Want to Grow Mushrooms

How is a graduate student in applied mycology—and a lore-only Warhammer fan—supposed to survive in a place like this? Fortunately, Lino’s cheat ability is a portable mushroom farm. First, he takes odd jobs to save up for mycelium and growth media. Then he opens the farm interface and starts growing mushrooms. After that, he sells the mushrooms, buys equipment, and expands production. At first, Lino thinks he can only grow ordinary mushrooms. Until one day, he encounters Ork spores—and everything changes. Who says growing mushrooms can’t save the Imperium of Man? — Description from novelcodex.org
