Dian Wei and Zhao Feng followed Huang Xu to Huang Zhong's house. It was a small yard southwest of the village. The decorations in the yard were extremely simple and there were no miscellaneous items.

"Mom! Guests are here! I'm here to find dad!" Huang Xu shouted into the house.

"Oh, it's out." As soon as the words in the house were finished, the door was opened with a creaking sound. A woman walked out of the house, although she was dressed in ordinary clothes or shabby, but her temperament was not stained by mud, which really made Zhao Feng's eyes lit up.

"Uncle, this is my mother, Yao." Huang Xu said.

"Xu'er, who are these?" Yao asked.

"Sister-in-law, my name is Zhao Feng, and my courtesy name is Zihu. He is a scholar who came to study abroad. I heard that Brother Huang Zhong had the courage to be a thousand men, so I came to visit him now." Zhao Feng said.

"It turns out that I came to find Han Sheng. It's really a coincidence. Han Sheng said that he had a toll on the government office today and might not come back until the hour of You." Yao said.

"It's okay, I'll wait here." Zhao Feng looked like he would not leave if he was beaten to death, but he would not leave if he couldn't be beaten to death.

"Then please ask the two to go into the house for a while." Yao didn't want Zhao Feng, a stranger, to enter the house, but seeing Zhao Feng insisting on waiting, and he didn't look like a bad guy, he invited the two to go into the house for a rest.

"Thank you, sister-in-law." Zhao Feng bowed to Yao.

"Sister-in-law, I think my son seems to be suffering from illness?" Zhao Feng asked after entering the house.

"Hey! Yes, I found a lot of doctors, but none of them could cure Xu'er's disease." As he said that, Yao almost cried.

"Sister-in-law, don't be in a hurry. I know two miraculous doctors. They should be able to cure the son's illness!" Zhao Feng said.

"Really?" Yao asked in surprise.

"Yes, sister-in-law, one of these two people is Hua Tuo, who is good at surgical treatment, and the other is Zhang Zhongjing, who is good at internal medicine. Both of them are also mastering Mr. Zhang Bozu, and their medical skills have made achievements." Zhao Feng said, "And if they are not good, then I will ask Mr. Zhang Bozu to take action. I believe that the son's illness will definitely be cured!"

"Zhang Bozu?!!" Yao was overjoyed, "Is it that Zhang Bozu from Changsha?"

"That's right!" Zhao Feng nodded with a smile.

"The sky has eyes! The sky has eyes!" Yao cried with joy, "Xu'er, you have saved it, you have finally saved it!"

"Sister-in-law, if you can, I will clean up today and set off tomorrow and go back to Changsha with us." Zhao Feng said.

"Okay, okay, I'll clean up now!" Yao's concern for Huang Xu's safety, nodded quickly, as if afraid that Zhao Feng would not take them to see Zhang Bozu, so he quickly got up and packed up.

"My wife... sister-in-law, aren't you afraid that I am a bad person?" Zhao Feng was shocked by Yao's actions. Is this too quick?

"No, how could you lie to me as a woman who has nothing to do with you in dress like this? Moreover, I don't think you are a local, so you travel thousands of miles to lie to me as a village woman?" Yao replied.

"Okay, sister-in-law, you don't have to worry about it. After Brother Hansheng comes back, you will tell him about this before making a decision." Zhao Feng said.

"Yes, I'm too impatient. You sit here and I'll prepare dinner for the evening." Yao said.

"Sister-in-law is not busy for now. We just came here after dinner. Let's wait for Brother Hansheng to come home to have a meal together." Zhao Feng stopped Yao's actions and said.

"Then, okay, just wait for Han Sheng to come back together." Yao nodded, sat down again, and continued to sew the clothes that had not been sewn just now.

"What is this Huang Xu disease? Do you know? Qing'er." Zhao Feng came to the system space and started communicating with Qing'er.

"Hmm? Now I remember to ask me about this lady?" Qing'er said.

"Hehe, good Qing'er, tell me brother." Zhao Feng said.

"Hmph! I'll give you so much knowledge to you for free!" Qing'er said, "Look at Huang Xu's blushing face, sweating, skin scratches, and muscle trembling. What are the symptoms?"

"Is this... mercury poisoning?" Zhao Feng guessed in a low voice.

"bingo!" Qing'er said, "It seems that the stupid brother is still not that stupid!"

"Wait, Qing'er, I have suspected that he was mercury poisoning before, but this was ancient times, how could mercury poisoning occur?"

"What happened in ancient times? Is there no mercury in ancient times? In nature, mercury mostly exists in the properties of compounds, mercury is compatible with copper and sulfur, so most of the mercury is distributed in the form of mercury sulfide (cinnabar). It is estimated that Huang Xu must have been exposed to cinnabar, and it is not a minority!" Qing'er said.

"It seems that's the case!" Zhao Feng scratched his head and exited the space. "Sister-in-law, I'll ask you, what did the son come into contact with before he was poisoned, or where did he go alone?"

"What? No, right? It seems that he went hunting alone when he was 9 years old, and then he came back and became like this!" Yao thought for a while.

"That's right? Xu'er, do you still have an impression of what happened to you when you went hunting? Can you tell me?" Zhao Feng asked.

"Well!" Huang Xu thought for a while, "That was the first time I entered the mountain by myself. At first, there was nothing, but later I hunted a hare. I was very happy. It was the first time I had something by myself. Then I saw a wild boar. I chased the wild boar for a long time. Finally, it seemed that I had arrived at an unknown cave. The cave was full of red stones and stones, which were very beautiful. I picked up a piece of the moderately sized and most beautiful one and took it home. Since then I got this disease."

"Is that stone still there now?" Zhao Feng was shocked. As Qing'er said, Huang Xu had come into contact with cinnabar!

"Here, because it's very beautiful, I keep it all the time, uncle, look!" As he said that, Huang Xu took out a blood-red stone from his pocket, which was exactly what Qing'er said about cinnabar!

"Xu'er, if I tell you, your disease comes from this stone, do you believe it?" Zhao Feng looked at the cinnabar and said.

"Ah? No way? How could a small stone make me sick?" Huang Xu couldn't believe it.

"This stone is called cinnabar, which is a mixed mineral! It contains a toxic substance. If it is worn for a long time and has not been processed, it will cause poisoning!" Zhao Fengdao.

"You mean Xu'er was poisoned? Not sick?" Yao said.

"Well, Xu'er is mercury poisoning! If she doesn't treat her in time, she may..." Zhao Feng didn't continue.

"It turns out that it's all because of this broken stone!" Huang Xu was angry.

"Well, go and bury this harmful stone. I don't know how to detoxify this thing, but it is true that Mr. Zhang is good at. When you arrive in Changsha, you can all the poisons you will get rid of!" Zhao Feng nodded.
