Hun Junlan’s small face was very serious. "Zhu Yanyi studies Traditional Chinese Medicine. I study our tribal medicine. They are different, but both come from ancient ancestors. Let’s just talk about tribal medicine. We mainly use herbs, but sometimes we need acupuncture. However, we mostly use moxibustion with herbs. Needles are too strange for us. Even my dad, who learned acupuncture, can only use silver needles now. She only uses them if absolutely necessary. My dad said acupuncture is the most profound part of our heritage. If done well, it can remove all pain from the body. But if done carelessly, it can take a life. The hardest part is using gold needles."
Ma Yaya spoke up. "I see gold needles and silver needles are both needles. What’s the difference?"
Hun Junlan’s expression became even more serious. "That’s because you don’t know the difference. To others, they look the same. But those who know traditional medicine understand the only difference: gold needles are very soft. Not just a little soft. Have you seen gold rings?"
"Of course I have," Ma Yaya said, glancing at Hun Junlan. Her family wasn’t poor, so she had seen gold rings.
"The gold used today has other metals mixed in, so some rings feel hard. But pure gold rings are soft. Many older people know that to check if gold is pure, you just bite it. Silver is much harder. If you don’t believe me, compare a gold ring and a silver ring at home. Gold is definitely soft. Gold needles and silver needles are the same. Gold needles are thin and long, but also soft. So, someone using gold needles must control their strength and be very precise. If they miss, it could be fatal. If they can’t pierce the skin, the illness can’t be cured." Hun Junlan explained to them.
"Based on what Hun Junlan says, Zhu Yanyi’s medical skills are very high," Zheng Feier said seriously.
"Yes," Hun Junlan nodded. "Definitely higher than my dad’s. I think I should learn more medicine from her."
"Is that how geniuses always make people feel bad?" Zheng Feier asked without thinking.
Luo Kun laughed loudly. "It seems our roommate is not simple. But it doesn’t matter. We are still roommates."
"She is not simple, and you are not simple either," Ma Yaya said, glancing at Luo Kun. Perhaps no one in their special recruitment dormitory was simple.
At that moment, Zhu Yanyi, the genius they thought was not simple, was talking to Grandpa Yao about something.
"Grandpa Yao, I want to show you something," Zhu Yanyi said. She took a roll of thread from her medical box and handed it to Grandpa Yao. "Grandpa Yao, look at this. What do you think?"
"Is this the thread you use to sew wounds?" Grandpa Yao looked at it. The thread was pure and even in thickness. It looked like catgut, but seemed different from what they usually used. There was a faint medicinal smell on it. With his years of medical experience, he knew this medicinal thread was special. "This is not ordinary surgical thread."
