Ning Yue smiled. "I know how to make it."
Crash…
The fragments in Uncle Su's hand fell to the ground again. He looked at Ning Yue in shock. He didn't expect this woman to not only be a divine doctor, but also know how to make ice!
What a genius.
The ice cubes were basically made in the winter and stored in the icehouse for use in the summer.
For various reasons, ice was not easy to store. Therefore, in summer, ice was a hot commodity. If Ning Yue could really make it, she would be a walking money bag!
Uncle Su looked at Jiang Ying eagerly, wishing he could agree on behalf of Jiang Ying.
Jiang Ying did not agree or refuse. He had seen Ning Yue's information. How could a young lady know how to make ice?
He couldn't help but ask, "What are the materials used to make these ice cubes? Are they expensive?"
"Do you have saltpeter?" Ning Yue asked.
"What do you want that for?" Jiang Ying frowned.
