Right when the firing room for cement was built, Roland had already assigned labs for the several follow-up projects. Most of the labs were being built around the North Slope Mine area so that the labs could be efficiently guarded—the construction of the labs was speedy due to their simple composition of adobe walls and wooden roofs. And their construction would not intervene with the construction of the city wall.
The saltpeter purchased from Willow Town was delivered to the nearby warehouse to be stored. It would be ground, measured, and sent to the labs when it was time to use them. Charcoal and sulfur would go through the same process. The transport and mixture of the three ingredients would be completed by different groups of people. This way, Roland could eliminate the risk of the plan being leaked out.
Roland took 20 pounds from the pre-made gunpowder, and slowly poured it onto a cropped sheepskin.
