"A bathtub? What do you need my bathtub for?" Long Xingxing asked, puzzled.
Chu Yang said, "You don't need to know that."
After thinking for a moment, Long Xingxing said, "I don't have a bathtub, but I do have a soaking tub."
"However, since I have a hot spring here, I hardly ever use the soaking tub, so it might be a bit dirty."
Chu Yang said, "It doesn't matter if it's dirty, just wash it."
Long Xingxing said, "Alright then, my soaking tub is in the bathroom."
Chu Yang told Liu Dan, "Go to the bathroom and scrub the tub clean, then fill it with more than half of water, I will need it for later."
Liu Dan replied and turned to enter the bathroom to scrub the tub.
Chu Yang went to the dining room, placing the Jade Cicada Shell and other necessary herbs on the dining table.
Curious, Long Xingxing came over to Chu Yang and asked, "What are you going to do?"
"Make medicinal powder for the medicinal bath," said Chu Yang.
