The sound of banging metal echoed along with the sound of water vapor. A large steam engine with six spider-like water pumps kept moving up and down. In the center of the machine was a large glass chamber. Inside was an egg with a transparent shell.
This machine was a caecilian egg incubator.
The dwarves seem to be working diligently despite the humid and hot conditions in the cave. Some of them put firewood into the combustion engine. Some checked that the iron pipes on the machine were not leaking. Some are keeping the water tank in the steam engine from running out. They all work together to ensure that the incubator machine continued to work perfectly.
It has been twenty-five days since the incubator machine was built. The process has only reached 90%. Although not fully completed, the incubator can already be used, although not automatically. Therefore, the dwarves have to do some work manually.
