But in ancient times, artificial rainfall was not possible.
However, constructing water conservancy was.
"Chu Yuxiao, do you have any water conservancy projects here?" Su Yan asked.
Chu Yuxiao looked at her sideways, puzzled, pursed his lips, and asked,
"What is a water conservancy project?"
Su Yan thought that perhaps the term was too modern for him to understand.
"It's about building reservoirs in some central areas, storing water in winter, and using it for irrigation during summer droughts."
A glint of light flashed in Chu Yuxiao's eyes.
He stared at her intently, a thoughtful shade crossing through his dark pupils.
"How do you know of this method?"
Well, looking at him, it seemed they hadn't built reservoirs to store water here yet.
"I saw it in a travelogue. It's been so long, I can't remember which one," Su Yan fabricated a reason.
She couldn't tell him her origins yet, perhaps one day when he fully trusted her, she would tell him.
