When Master Wu heard his son's words, his eyes lit up.
The weather was hot then.
Even in the capital, there weren't many families that could afford to use an ice basin.
If he could get the recipe for making ice and use it for others to do him a favour in the capital, there would definitely be endless benefits.
He could also make ice and sell it at a high price to those who were rich but lacked ice.
Master Wu thought for a moment and said, "Get that Fourth Son Shi to talk to that wretched girl and see if she can sell this technique."
In his opinion, she was a wild girl who did not have much experience.
That was why she would sell them the little black balls with 600 taels of silver the previous time.
Eldest Young Master Wu nodded. "Alright, I'll go and look for Fourth Son Shi now."
Just as he was about to leave, Master Wu asked, "How's the progress of those little black balls?"
