"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 clear 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, which could provide space for one person to walk, so the three of them lined up in a row, walking forward, middle and behind.
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 a dozen 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 coming out constantly.
"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.
Di Qiongyin thought, if this is the water source for the residents of Shijiu Town, then the spring water contains cryptotoxin. Xu Qingyun will be poisoned if he drinks the water like this.
Xu Qingyun stood up, smiled and said: "My body is different from ordinary people. I am invulnerable to all poisons. Moreover, this spring water is not poisonous. I have tested it out."
Di Qiongyin and Mo Yanyu relaxed after hearing this.
But then, Di Qiongyin became confused again: "Without Yinkui's poison, wouldn't Yinkui flower be here?"
"Yes, Yinkui flower is not here. Although it is dark and humid here, it is surrounded by rocks and there is no soil suitable for Yinkui flower to grow." Xu Qingyun said.
"Yin Kuihua, if you're not here, where could you be?" Di Qiongyin became even more confused.
Mo Yanyu said at this time: "When we came in, there was a fork in the road that we didn't explore."
Xu Qingyun nodded, and Mo Yanyu thought about it together.
"That's right, we have to go back. Yin Kuihua may be right in front of that fork in the road." Xu Qingyun said.
Several people then left here and walked back.
After walking back for a few minutes, we came to a fork in the road, where there was another fork.
Several people stood in front of this fork, looking inside.
The golden light in Xu Qingyun's eyes flashed away, and the Eyes of the Candle Dragon opened.
Look directly into the fork cave.
The dark cave in front of him became brighter in Xu Qingyun's eyes, as if he were looking at objects during the day, and his sight became farther and farther away.
After a while, Xu Qingyun withdrew his gaze, and just as he was about to close the Eye of the Candle Dragon, he couldn't help but catch a glimpse of Di Qiongyin from the corner of his eye.
Xu Qingyun took one look, was slightly startled, and then took a second look.
"Doctor Xu, what's wrong?" Di Qiongyin noticed Xu Qingyun looking at her and couldn't help but become confused.
"It's okay." Xu Qingyun shook his head and looked away.
But in his heart, he was surprised.
Xu Qingyun used the perspective of the Zhulong Eye and accidentally discovered Di Qiongyin's biggest secret.
She turned out to be a girl.
Xu Qingyun didn't know what method Di Qiongyin used to change his gender, but under the eyes of the candle dragon, all disguises were useless.
The eyes of the candle dragon saw through Di Qiongyin's daughter.
Xu Qingyun thought to herself, no wonder Di Qiongyin's face is more beautiful than a woman's, it turns out she is a woman.
I just don't know why she wanted to hide her daughter's identity. Xu Qingyun thought about it and could actually guess some.
Although Di Qiongyin's disguise had been seen through, Xu Qingyun did not point it out.
Xu Qingyun recovered his thoughts and said, "Let's go, Yin Kuihua should be in this fork."
Xu Qingyun just used the Eye of the Candle Dragon to explore and already made a discovery.
Xu Qingyun and others entered the fork cave. There was also a stream here, but it was smaller. This stream was like a tributary and would eventually merge into the mainstream.
Xu Qingyun leaned down directly, picked up a handful of water and put it into his mouth just like before.
This time, Xu Qingyun felt that the stream clearly contained Yinkui toxin.
"It's true, we have found the right place. There is Yinkui's poison in the water this time, and Yinkui flower must be right in front." Xu Qingyun said.
"Very good!"
When Di Qiongyin heard this, her face showed joy.
By finding Yinkuihua, not only the residents of Shijiu Town were saved, but her mother was also saved.
