But he only had twenty-six copper coins in his pocket, not enough to buy a bag of urea, so he had to earn money immediately.

Their rice paddies weren't far from a water source, but they had to carry water by hand, which was too inefficient. Even if Zhao Xiaosheng and Zhao Xiaoshan worked until dark, they still couldn't irrigate their small rice paddy properly.

After examining the terrain and water sources, he had a clear idea of ​​what to do and wanted to build a waterwheel immediately.

He called his two younger brothers to his side and began to instruct them. The two brothers looked at him blankly, not knowing what their scholar brother meant.

“Little Sheng, it’s about fifty steps from the river to our rice paddy. You can dig a ditch, which should take about an hour. I’ll go back and build a waterwheel, so we won’t have to carry water anymore.”

It would be ideal to have water in the fields without having to carry water for irrigation, but they had never heard of a waterwheel before.

"What is a waterwheel? Can it really draw water to irrigate rice paddies?" Zhao Xiaosheng asked with a look of surprise.

“There is a record in the ancient book that I will take Xiaoshan back to make a waterwheel. Now you dig the ditch, and dig the ditch deeper so that the water can flow into the rice field.”

Zhao Xian didn't know how to explain it, so he could only say that it was in an ancient book.

"Okay, I understand."

Zhao Xiaosheng began to survey the terrain and choose the best route for digging ditches.

"Xiaoshan, come back to the village with me to build a waterwheel." After saying that, Zhao Xian quickly led Zhao Xiaoshan back to the village.

The scholar was a learned and knowledgeable man. I wondered what kind of waterwheel he was talking about. If this thing could irrigate, then the brothers wouldn't have to carry water anymore, which made me very happy.
