It's still embarrassing to show you, but there's a pottery I'm working on these days.
Um...this is a secret, but if you help me, I'll tell you.
Can you help me?
It's to use the Rough Stone...
If Rough Stone is well processed,
the porcelain can be made to let air flow well in and out.
When you put warm food in it, you can keep it longer than any other bowl.
Thus, the price will also go up.

Rough Stone is precious here.
It's a scarce mineral.

Thank you. Will you help me again?
You are the only one who knows my secret.
