Although Su Wan's voice was not loud, Chu Mohan's hearing was very good, and he heard what Su Wan said very clearly.

Su Wan knew that Chu Mohan heard what she had just said.

pouted his lips and returned to preaching; "Then I'll pack up and get ready to leave in the afternoon."

The group had lunch.

The slammers have arrived.

Leading the way was a tall, thin middle-aged man.

The tall and thin man walked up to Chu Mohan and saluted Chu Mohan: "The grass people see the night king, the grass people are the masters of the Ancheng County Ya, and the grass people's surname is Li." ”

Except for Chu Mohan, Master Li didn't know the identities of the others.

Obviously, Chu Mohan didn't want to tell him either.

In addition to Master Li, there are more than 20 officials.

The Ancheng County Commander wanted to come in person, but he could think of Chu Mohan's words, he was afraid of making Chu Mohan angry, so he had to let the master and the officials who had been carefully selected by him come.

The breeze coughed lightly; "Take us to the villages where the strange disease is happening."

Master Li responded.

The crowd came to Sheung Shui Village, the closest village to Anseong.

Master Li introduced; "Sheung Shui Village is the closest to Anseong, this village is located in the middle of the mountain, there are a total of more than a dozen households in the village, because it is located in the middle of the mountain, most of the villagers in Sheung Shui Village are elderly."

Su Wan wondered; "What about the young people in the village?"

Master Li sighed; "Most of the young people in the village have moved to Xiashui Village down the mountain."

Master Li pointed to the village at the foot of the mountain, and he sighed again; "It's a pity...... It's a pity ......"

Su Wan shook his head while sighing when he saw Master Li, and said suspiciously; "What a pity?"

Master Li said; "It's a pity that the villagers who moved to the foot of the mountain also survived."

Su Wan frowned; "Master Li, do you mean that the villagers of Xiashui Village also have that strange disease?"

Master Li nodded; "There are a total of four villagers who have that strange disease, Shangshui Village, Xiashui Village, Liujia Village and Mojia Village."

Mojia Village is the village that Su Wan and others passed by when they came to Ancheng.

Su Wan asked; "Except for these few villages, no other villages have found strange diseases?"

Master Li shook his head; "Except for these four villages, there are no strange diseases in other villages."

Su Wan let out an "oh".

Su Wan looked sideways at Chu Mohan and said with a smile; "I walk around."

Chu Mohan nodded.

The village is not big, there are only a dozen families, from the head of the village to the end of the village, it didn't take long for Su Wan to see more than a dozen new tombs on the hillside.

Su Wan thought that these new graves should belong to the villagers.

Compared with Mojia Village, there are indeed a lot fewer villagers in Sheung Shui Village.

Su Wan circled the village.

"Did you find anything?" Bi Xiaoyao asked.

Su Wan shook his head; "Nothing has been found, the villagers have already been buried, more than a month has passed, and the corpses of the villagers should have decomposed and turned into white bones by now."

Bi Xiaoyao frowned; "Can't we find the similarities?"

Su Wan Dao; "Let's go to Xiashui Village at the bottom of the mountain first."

Master Li led the group to Xiashui Village.

"In fact, this Xiashui Village and Shangshui Village were the same village before, but many of the villagers in Shangshui Village moved to live at the foot of the mountain, so there was the last Xiashui Village."

As before, Su Wan walked around the village.

The last group came to Liujia Village.

It was already dusk.

This time, Su Wan did not go around the village as before.

Looking at the sunset on the horizon, the corners of Su Wan's mouth were slightly hooked.

Although she didn't know what kind of disease the villagers had, she already knew how the villagers got sick.

Chu Mohan saw a confident smile on the corner of Su Wan's mouth, and he thought that the little girl should know something.

"It's getting dark, let's go back." Chu Mohan said.

Before the sun had completely set, the group returned to the inn.

They were separated from Master Li and them at the Ancheng City Gate.

As soon as he entered the inn hall, Bi Xiaoyao shouted that he was hungry; "I'm so hungry that I haven't even drunk a sip of water this afternoon."

The group found a place to sit down, and Xiao Er immediately served a pot of tea.

Bi Xiaoyao poured a cup of tea for everyone.

Su Wan slowly drank the tea in the cup and asked; "Have you noticed anything in common between these villages?"

Su Wan saw that Chu Mohan and Ye Youjing looked calm and unhurried, and knew that the two of them had discovered the common ground between these four villages.

Leng Xue'er and Bi Xiaoyao were confused.

The two shook their heads.

Leng Xue'er wondered; "What do these four villages have in common?"

The corners of Su Wan's mouth raised slightly; "Some of these four villages are relatively close, such as Shangshui Village and Xiashui Village, and some are relatively far away, such as the village we passed by when we came to Anseong, but these four villages have one thing in common, that is, there is a river next to the village that is not very wide."

Leng Xue'er thought about it, and really told Su Wan that there is a river next to these four villages.

Bi Xiaoyao Road; "You mean, the villagers drank the water from that river to get this strange disease?"

Su Wan nodded; "It's entirely possible, I'll ask Qingfeng to get a map of Anseong when I come back."

Before Su Wan's words fell, the breeze just walked into the inn.

Su Wan waved at the breeze.

A light breeze walked over to the table where they were sitting.

Su Wan asked; "Did you get a map of Anseong?"

The breeze said respectfully; "The map was given to his subordinates by Master Li."

Light Breeze pulls out the map from her bosom.

He spread the map onto the table.

Su Wan pointed to a certain river on the map; "You see, this river is the river next to those four villages."

Everyone's eyes fell on the river that Su Wan pointed to.

The river actually flowed through the four villages.

There are exactly only four villages located on the river.

Bi Xiaoyao raised his eyebrows; "It seems that the water is polluted, and the villagers will get a strange disease when they drink the polluted water, so people who do not return to the village all year round do not get a strange disease."

Su Wan pointed to the small river channel with a white finger; "If we want to find out why the villagers are sick, we have to go down the river to see if there is anything wrong with the river."

Knowing that there was a problem with the water that the villagers drank, the villagers contracted a strange disease, and early the next morning, Su Wan and his party went upstream.

Today, Chu Mohan only picked a few, after all, he was familiar with the nearby terrain.

The crowd came to Sheung Shui Village again.

The river was left from the mountains.

"Are you ready?" Just in case, Su Wan asked everyone to prepare food and water.

You can't drink the water here, and if you drink it, you don't know if you will get sick.

"I've got everything with me."

"Then let's go."

The group walked along the riverbank all the way up the mountain.

After walking for a short time, we came to the end of the river.
