After handling the matters of the Divine Pill and the Southern Wei people, Zhao Yao began to busy himself with establishing the water mill workshop. Previously, he had designed the Water Wheel to solve Lingnan's irrigation problems. Later, he created windmills to address the harvesting issues, but after harvesting, rice needs to be processed to become edible.
Regarding grain processing, not just Lingnan, but the entire Great Zhou relied on the ancient mortar and pestle passed down from the previous dynasty. These tools were not only time-consuming and labor-intensive but also yielded little grain, making them highly inefficient.
Zhao Yao initially did not notice this problem. When the whole of Lingnan was busy harvesting the second season of rice, he discovered this issue.
He thought of the world in Zhao Yao's dreams where the Song Dynasty used water mills to process grains, and thus he planned to recreate all those water mills from the Song Dynasty.
