Chen Hui thought that Prince chang would wait in the prince's mansion as before, but he didn't expect that he would go with Chen Hui.

Naturally, Chen Hui could not refuse. Now he went out with Prince Chang.

Prince Chang had arranged to follow Chen Hui, and the warrior who was under Chen Hui's command wanted to follow him, but Prince Chang waved him to retreat.

Just as Chen Hui and Prince Chang just left the palace, the warrior in charge of taking medicine came back with a huge burden on his back.

The burden is naturally the medicine Chen Hui wanted.

In front of Prince Chang, Chen Hui opened the burden outside the prince's house, and according to the dosage of the prescription, asked the warrior to suffer from the decoction.

If this kind of thing is carried out in the prince's house, Prince Chang will not conflict with it.

Chen Hui explained the amount of water in detail, and told the warrior to endure for a long time. After suffering, he immediately sent the decoction to the home of the sick civilians in Hengcheng for them to drink.

This kind of thing Chen Hui just needs to tell him. Prince Chang will naturally let these warriors do it.

"Check the water first." Chen Hui said: "the last time shuizu Hengcheng was investigated from the source of water."

Prince Chang and Chen Hui were walking in the streets of Hengcheng. All the warriors and civilians who saw Prince Chang saluted him and retreated to the roadside. After Prince Chang and Chen Hui passed, they left quickly.

Chen Hui noticed this scene. When he saw another civilian retreat to one side, Chen Hui paid a little attention to his look.

There was a look of fear on the civilian's face. Chen Hui could not help but judge Prince Chang more in his heart.

Chen Hui lived in the capital before, and the Lord of the city was Peng. Even before Peng became the Lord of the city, the civilians in the capital didn't show fear when they saw the two greedy guys, the former Lord of the city and the wizard.

Chen Hui also went to Hengcheng, the Shui nationality. At that time, there was the black emperor of the Shui nationality. The people of Hengcheng of the Shui nationality would salute the black emperor of the Shui nationality and the Lord of Hengcheng, but they didn't show such fear. They all saluted respectfully.

The same is true of the King City of the wood nationality. The common people will salute when they see the warriors and witches, but no one shows such a look of fear. They all look respectful.

When people in Hengcheng city saw Prince Chang, they were afraid to take the place of reverence. It only showed that Prince Chang was very strict in his administration of his fiefdom.

"What happened in Hengcheng of Shui nationality?" Prince Chang asked at this time.

"It's caused by the infection of prey brought back by hunting." After a brief answer, Chen Hui asked, "how many wells are there in Hengcheng?"

"Three Prince Chang spoke and walked leisurely.

Chen Hui followed Prince Chang and soon arrived at the first well. Chen Hui pumped some well water and drank it directly. After about ten minutes, Chen Hui slowly shook his head and said, "there is no problem with the water source of this well."

Prince Chang didn't ask much. He took Chen Hui to the second well.

Chen Hui still fetched water and drank it directly.

The well water is slightly bitter at the entrance. This is the bitter taste of Chen Hui's medicine. This bitter taste is very mild. It's not something that people who have been dealing with medicinal materials for many years can't drink, especially after heating.

"The water source of this well is not quite right." Chen Hui said: "I'm a warrior. I don't have any symptoms. I asked Prince Chang to order hengchengzi people to drink well water for observation."

Prince Chang waved his hand directly, attracted a civilian and said, "drink some well water!"

This civilian quickly took Chen Hui's water ladle and drank a large ladle full of well water. Within five minutes of drinking the well water, he began to get a little hot, but his own feeling was a little cold.

Chen Hui reached out to his forehead and said, "go to the prince's residence, find the warrior who is suffering from medicinal herbs, and ask for a bowl of soup to drink. After drinking it, it will be better!"

When the civilian heard Chen Hui's words, he looked at Prince Chang.

Prince Chang waved his hand before the civilian dared to leave.

"The water from this well can't be drunk by Hengcheng people for the time being." "Let's go to the last well," Chen said

There is no problem with the third well. The Qing emperor put all the pills given by Chen Hui into the second well. After a few days, the effect of the pills decreased a lot. This is also the reason why the common man had a fever like symptom, but he didn't feel powerless.

"This time Prince Chang granted the land to the people who got sick, it didn't infect people. It was just that the people who drank the well got sick." Chen Hui said at this time: "it can already be concluded that it is a water source problem!"

Prince Chang frowned and asked, "the water in this well can't be drunk in the future?"

"You just need to deal with the water." Chen Hui said.

"I'll trouble the tiger warrior." Prince Chang said, "it's getting late. The dinner should be ready. Let's go back to our house."

Chen Hui followed Prince Chang back to the city Lord's residence. He first selected some medicinal materials and ordered them to be boiled into soup and poured into the second well.

In fact, there are many civilians who have drunk the second well. Although the medicinal materials are enough, the decoction is not enough. At least it needs to be boiled several times.

Prince Chang naturally would not let Chen Hui continue to take care of the decoction. After Chen Hui grasped the medicinal materials, he took Chen Hui to the dinner party.

The dinner party was set in the wing room on one side of the city Lord's mansion. In order to show our gratitude to Chen Hui, we naturally need someone to accompany us.

The company is the wizard and warrior of Hengcheng.

However, the warriors of Hengcheng left one after another after they had enough to eat. Their reason for leaving was to replace other warriors on duty.

Prince Chang didn't say much. After they left, he ordered people to take down the banquet and serve a table again.

This time, there were not many dishes, but they were more exquisite than before.

After the warriors left, only prince Chang and the wizard of Hengcheng were left.

Hengcheng, the wizard, is a sixth level cultivation, but not a alchemy wizard. Instead, he chooses to continue to practice in preparation for the seventh level cultivation.

Chen Hui has already known about the relationship between Qingdi and Prince Chang. Naturally, he knows that this wizard is one hundred percent of Prince Chang's people.

"It's quiet at last." Prince Chang picked up the wine pot and poured wine for Chen Hui himself. He said, "tiger warrior, before I came to Hengcheng, who can tell you something?"

"Yes!" Chen Hui said quickly, "a wizard who is familiar with me tells me that I will answer whatever Prince Chang asks, and everything will be answered truthfully."
