Wu Xiaoyu rushed into the room, and when she came back, she had something extra in her hands.
Looking at the unlabelled bottle in her hand, Wang Dahai said, "This isn't essential oil, is it?"
He took it over, twisted off the cap, and sniffed.
Wu Xiaoyu said, "I remember now, Rongrong mentioned that this seems to be Safflower oil."
Wang Dahai hummed in approval, "It indeed is Safflower oil."
He guessed it must be because Qin Rong was often out on fieldwork.
Occasionally she would suffer from sprains or strains, or perhaps she kept it on hand at home because long-term fieldwork caused backache.
However, she couldn't possibly reach her own back, could she?
Wu Xiaoyu asked, "Can this be used as essential oil?"
"It can be used as well."
"Are there any side effects?"
"There aren't any," Wang Dahai said with a smile. "Essential oils only serve as a lubricant, whereas this Safflower oil can also relieve fatigue. It's actually much better than essential oils."
"Really?"
