Li Yu put away the gift and returned to the foot of the mountain. Seeing that Xiao An was still guarding the charcoal pit, Li Yu saw that he had already blocked the vent. She checked and said, "Xiao An, there's no need to watch here. We'll pick soapberries. We'll come back tomorrow morning to get the charcoal."
"Okay." Xiao An carried the backpack. "Sister Li, what's a soapberry?"
"It's a fruit that can be used to wash things. The seeds inside are medicinal herbs." Li Yu brought Xiao An to the forest with the soapberry trees. Seeing that most of the soapberry fruits were ripe and most of them had turned brownish-yellow, Li Yu pointed at the fruits. "Look, these are soapberry fruits. Xiao An, pick them at the low places. Only pick the yellow ones and don't pick the green ones."
