I Grow Mushrooms in Another World

I thought I could learn magic, make gunpowder, and realize Industry 2.0 In another world by traveling to a so-called alien world. However, I found that the rules were different. I could only adapt to local conditions and create a fungal version of industrialization, from muscle engines to wetware processors, from spore "air guns" to biological mechas... "Sir, limestone-secreting bacteria have grown in the mushroom house, and we have no food rations!" "Mixed into the mud and sold as cement, the children next door were so greedy that they cried." "Sir, the steam engine you are talking about is more powerful than a sheep, not to mention the horsepower!" "Look at this mycelium, which is long, white and elastic. Use it to make a muscle engine." "Sir, a woman has grown out of the ground and claims to be the Queen of Fungi!" "Bring it to my room..." This is the story of a doctor of microbiology who was infected by a mysterious fungus and traveled to another world to comprehensively build Fungus Industry 2.0.
