Having received a wooden token, Kevin finally officially moved into St. Louis.
This place looked like a prison, but it had already become an underground city.
It had its own mines, the slag from which would be mixed and calcined to produce good building materials.
It also had relations with other places; some of the lumber mills had been bought up by the Angel Envoys and were continuously supplying raw materials here.
After careful calculation, Kevin found the amount of materials needed here was absurdly large.
The resources of the entire Yifate seemed barely sufficient to satisfy the appetite of this prison, and the modified steam engine was like a terrifying beast, ingesting the raw materials and churning out products.
The system here was also quite peculiar; Angel Envoys and residents were intermixed, forming numerous guilds, coordinating their respective production lines to keep producing a variety of products without interruption.
