Next, Wong Qiao poured lamp oil into the small iron trough, lit a few wicks, and placed them under the stand holding the water canister.
As the heating process began, Wong Qiao pointed at the lit wicks and the small water canister and began explaining, "Our machine is too small, so we can only heat it using the oil lamp method. Previously, when we experimented with the steam engine in Peach Grove, we used charcoal fire. This model can only heat the water to boiling using the lamp wick, and as steam rises continuously and gathers..."
Under Wong Qiao's explanation, the water in the canister gradually heated up. Before long, an iron rod as thick as a matchstick began to push forward. As the rod advanced, the crankshaft and gears connected to the rod also started turning.
Through a few simple connected transmissions, the disc fitted with the small wooden monkey also moved. The wooden monkey on the disc's edge began to make rounds, initially very slowly, and then gradually accelerated.
