Zhao Yazhi in the room had a complicated expression, at first, she found a problem in a family with a fever, but this problem could not meet the conditions for the outbreak of the epidemic at all.

In medical books, the conditions and specific characteristics of the occurrence of epidemics are recorded, and the characteristics of epidemics are varied, but the conditions are the same.

After seeing one of them, Zhao Yazhi stood up suddenly, looked anxious, and shouted at the little guy beside her.

"Go and find them Huayan, I have something to tell them!"

Jiang Yin was summing up, and suddenly the people around Zhao Yazhi came running anxiously.

After hearing what the little maid said, Jiang Yin was shocked and ran towards the restaurant, Hua Yan and Bian Qing also followed, and Xie Cheng followed behind Jiang Yin with a few imperial doctors......

"Come and see, the book says that the disease may be due to the surrounding water source or the land."

Several people looked at the above record with solemn expressions, if it was because of the water source and land, this epidemic would definitely be more serious, and they had to find the problematic water source or land.

Zhao Yazhi looked at everyone and told her discoveries in the vernacular, she ruled out the causes of the epidemic one by one according to the records in the medical books, only water source and soil, she did not have the time and energy to study.

"I'll go, just leave this matter to me, and you can leave the method of judgment to me."

Zhao Yazhi looked at Jiang Yin in surprise, and when she was about to refuse, Xie Cheng beside her also said that she was going to investigate.

Hua Yan and Bian Qing, who were going to go together, could only take a step back, and the current affairs that Jiang Yin and Xie Cheng needed to deal with could not be replaced.

Zhao Yazhi handed the bottle she had prepared a long time ago to Jiang Yin.

"Okay, this is the way to judge, hard two, if you find anything, use this to bring things back."

Jiang Yin was originally a little surprised by Xie Cheng's voice, but now he is fully engaged in finding the source of the epidemic.

Xie Cheng looked at Jiang Yin with a serious face, and his heart softened.

In the following days, Jiang Yin and Xie Cheng walked together from the city to the outside of the city, but they did not find anything strange.

Time turned back to the day they first set off, and as soon as the two of them set off together, Jiang Yin said the doubts in his heart.

"Why are you involved?"

Xie Cheng smiled and told Jiang Yin the reason for his voice.

"Hua Yan and Bian Qing both have things to do, if they are allowed to go, they will have to rearrange people to go over, but the affairs in my hands, just arrange a imperial doctor to take office."

Jiang Yin nodded, if it was because of this, Xie Cheng would be worthy of being sent by the Holy Lord.

In fact, what Xie Cheng didn't tell Jiang Yin was that he originally planned to let Bian Qing and Hua Yan handle this matter together, but when he learned that Jiang Yin had the intention to take the job, he gave up his original plan.

In this way, Jiang Yin and Xie Cheng supported each other, they explored all the places, and the relationship between the two became harmonious as they advanced step by step.

Jiang Yin knew what Xie Cheng liked to eat, and Xie Cheng also understood Jiang Yin's thoughts better, and the distance between the two gradually shortened during this period of time......

"We didn't find the right water or land, and I suspect there are other reasons for the disease."

Zhao Yazhi smiled bitterly, when Jiang Yin and the others went out to find the source, the condition in the city became more and more serious.

Many people skip the fever stage and enter the final stage of the epidemic, which is only one step away from death.

Jiang Yin saw that Zhao Yazhi was in a hurry, she didn't know why the epidemic had developed so quickly, and they had only left for five days.

Zhao Yazhi copied out the record of herbs separately and handed it to Jiang Yin, this herb had been seen when she first came to this city, according to the habit of herb growth, Zhao Yazhi could conclude that there was definitely herb growth near this city.

"I need you to find a herb, as long as there is this herb, I can prepare an antidote, even if I don't find the source, it doesn't hurt if I don't find the source."

"Okay, don't worry, we'll look for it, you've worked hard these days."

Zhao Yazhi looked at Xie Cheng's handsome face, smiled, and waved his hand to let Xie Cheng and Jiang Yin leave quickly.

The two didn't stay long, took the paper and left.

After the two left, Zhao Yazhi looked at the backs of the two and laughed coldly.

Xue Yuexin walked out of the curtain behind her, and the two of them looked at each other and smiled.

Jiang Yin and Xie Cheng walked outside the city, took out the content of Zhao Yazhi's excerpt, and compared the herbs in front of them little by little.

"Otherwise, we will memorize the characteristics of the herbs first, so that we don't have to compare them little by little."

Xie Cheng agreed with Jiang Yin's proposal, if each herb had to be compared in detail, even if they were given a month, they would not be able to compare all the herbs and weeds in this area.

Jiang Yin wrote down all the characteristics and went to the woods with Xie Cheng.

The two of them searched all the plants left and right, but they didn't find the herbs they needed, most of the herbs only met two or three characteristics, and the ones that matched perfectly never found them.

"It's getting dark, let's find an open place to make a fire, and we'll be here tonight."

Jiang Yin nodded and followed behind Xie Cheng, carefully dodging the thorns around him.

With the help of Xie Cheng, Jiang Yin successfully caught a little rabbit, and under the raging flames, the two of them fell asleep.

The next day, Jiang Yin got up from Xie Cheng's arms, a little confused.

As soon as Jiang Yin moved, Xie Cheng subconsciously opened his eyes and met Jiang Yin's shy gaze.

"Let's go ahead and look for it, find us sooner and go back sooner."

Jiang Yin avoided Xie Cheng's eyes, stood up, patted the grass clippings stained on his clothes, and left Xie Cheng's side, his hurried back full of shyness.

Xie Cheng smiled, without breaking Jiang Yin's cover-up, the two of them were looking for herbs like this, and where they didn't see it, Shen Yang was gathering momentum in the grass.

"Xie Cheng, come on, there is an herb here, and its characteristics are exactly the same as what is written on the paper!"

Hearing Jiang Yin's call, Xie Cheng came to Jiang Yin's side.

At this time, the two were on the edge of the cliff, and the herb that Jiang Yin found was on the edge of the cliff.

Shen Yang took advantage of the fact that the two of them were studying herbs, and pushed the two of them off the cliff with a push of both hands, and even the herb was taken off the cliff.

"It's a pity, I don't know when this epidemic will end......" Shen Yang smiled, turned away from the edge of the cliff, and prepared to return to the city.

Jiang Yin and Xie Wanwan never expected that someone would secretly kill them while they were observing the herbs.

Unfortunately, the man did not expect that this so-called cliff was actually a small canyon, which looked vertical and narrow, but in fact it was steep and low, and it was not so thrilling.
