Xue Ya'er agreed to Yao Zhi's request and glanced at Steward Han. He quickly went to fetch the brush, ink, and paper. It took him around 10 minutes to return. Besides that, he also asked people to carry a desk over.
After he prepared everything, Yao Zhi walked to the desk and picked up the wolf-hair brush. The ink had been ground, but Steward Han still stood on the side and ground more ink.
Yao Zhi drew the design for the bamboo water pipe, complete with the instructions, precautions, and how to maintain it.
As he ground the ink, Steward Han saw how fluid her movements were and couldn't help but look at her with amazement. No wonder he was the heir of the Nuwa Clan. His knowledge was far above that of ordinary people.
It took Yao Zhi 50 minutes to finish the design. Thinking that she was already at it, she decided to add the drip irrigation system. This type of irrigation fits the northern area since the land is located near the mountains and the ground height varies.
