"Dr. Xu, I actually don't understand why it takes more than ten years of Prunella vulgaris to pick Cynthia vulgaris?"
As Di Qiongyin walked, she asked the doubts in her heart.
Mo Yanyu also looked slightly sideways at Xu Qingyun, obviously she was also a little curious about this question.
Xu Qingyun smiled and explained: "This problem is actually related to the characteristics of Yinkuihua itself."
"The Yinkui flower is cold and yin, so it generally only grows in places with heavy Yin Qi. If it is picked improperly, the Yinkui flower will be destroyed."
"The attribute of Prunella Vulgaris is yang. After burning, the heat can dispel the yin and cold. One yin and one yang, the two are opposite."
After listening to Xu Qingyun's explanation, Di Qiongyin's eyes lit up slightly: "It turns out there is such a reason."
"Prunella vulgaris also has high medicinal value. It can clear away heat and purge fire, improve eyesight and liver, dissipate knots and reduce swelling..." Xu Qingyun said.
A few people walked quickly while talking about some topics about traditional Chinese medicine, and finally arrived at Shijiu Cave in Shijiu Mountain.
A gurgling stream flows continuously from Shijiu Cave.
This clear stream is the water source for the residents of Shijiu Town.
The Shijiu Cave ahead looks dark and unfathomable from the outside. It is a huge natural cave that has not been developed.
Xu Qingyun, Mo Yanyu, and Di Qiongyin entered the cave entrance easily.
The temperature outside is still very high, but when standing in the cave, there is a cool breeze blowing, and it feels very cool.
Just after entering the cave, there was still light. Inside the cave, the stream was gurgling, and the sound of falling water could be heard.
If you have leisure time and appreciate it carefully, you will find that this cave is also a kind of wonder and beauty.
In fact, Xu Qingyun didn't need a light and could still see in the dark, but Di Qiongyin and Mo Yanyu couldn't do it, so Xu Qingyun still prepared a lighting lamp.
The light illuminates the cave and we continue to explore deeper inside the cave.
A few people walked forward along the stream first.
The water washed out a narrow embankment that could be walked by one person, so the three of them lined up in a row, in front, middle and behind, and walked forward.
There were many bats on the cliff inside the cave. The bright lights seemed to alarm these bats, and they flapped their wings and flew around.
The atmosphere was tense, and it actually felt like an adventure.
The further you go inside, the lower the temperature becomes. At this time, the temperature is only over ten degrees.
Xu Qingyun himself doesn't feel cold because of this temperature, but he doesn't know what Mo Yanyu and Di Qiongyin are like.
"How are you doing? Are you feeling cold?" Xu Qingyun asked.
"Dr. Xu, I'm fine, you don't have to worry." Di Qiongyin said.
"Don't look down on people too much. I've experienced the environment of more than ten degrees below zero and carried out missions. This is nothing." Mo Yanyu said with disdain.
Xu Qingyun had forgotten that the two of them were actually not ordinary people.
Not to mention Mo Yanyu, Di Qiongyin seems to have some cultivation skills as well.
"This cave is really magical. It's so hot outside, but it's so cool here." Di Qiongyin said casually.
"This is the magic of nature." Xu Qingyun also said casually.
After walking for about half an hour, a clear spring suddenly appeared in front of me. The water in the spring was not big, and there were wisps of dense air constantly coming out.
"Is this the water source for the residents of Shijiu Town?" Di Qiongyin looked at the spring water and said.
Xu Qingyun did not answer. He went directly to the spring water, leaned down, picked up a handful of spring water with his hands, put it into his mouth, and tasted it carefully.
"Ah! Doctor Xu, it's poisonous, don't drink it!" Di Qiongyin screamed when she saw this.
Mo Yanyu also looked worried. This chapter has been completed!
