When Xu Qingyan heard the news, she looked slightly stunned.

She also wanted to test it again at night, so as to determine the way to crack it, who knew that this Qin County order hurriedly issued such an order, it was really a vigorous and resolute character!

But he can't be blamed, after all, it's been a year since this kind of strange thing happened in this county, and if it were a ruthless county order, I'm afraid they would have all been executed a long time ago.

After thinking about it, she had no choice but to ask Lingxian to take her worship sticker to the county office: "You tell Lord Qin that the county lord has found out, let him arrest people in a smaller way, catch the city first, and let the outside of the city go first, and then discuss it after tonight." ”

"Yes." The fairy took the post and went.

Xu Qingyan turned around and went back to the room, thinking about what to do next?

A prefecture-level county has a population of tens of thousands, and half of it is five or six thousand. So many people need healing, even if her merit and gratitude are really effective, she can't bear to make such a thing.

And she doesn't necessarily have that much merit! It's a really sad thing.

After half a pillar of incense, Xu Qingyan was studying the formation diagram left by her master, when she heard the spirit fairy report outside: "Miss, the county commander asks to see you." ”

"Wait a minute" put away the formation diagram, Xu Qingyan straightened her clothes, and then opened the door and said, "Let's go." “

In the lobby downstairs, Qin County Ling stood with his hands in his hands, and behind him stood two officials who had come in the morning, and when he heard the movement, he hurriedly turned around and bowed: "Louhuai County Ling Qin Cheng has seen the county lord of Le'an. “

"Lord Qin, please take a seat, and the spirit fairy will serve tea."

"I heard the fairy girl say that the county lord has discovered the strange things in this county, I don't know what I found, can I tell the lower officials to hear about it?" As soon as Qin Chengcheng sat down, he got straight to the point.

Xu Qingyan looked around, maybe Qin Chengcheng also knew the confidentiality of this matter, so he cleared the scene in advance, and at this time, there were no other idle people in the lobby except for them.

"It's been a year since the strange thing happened in your county, have you ever wondered why the sick man only had a seizure at night, but in the day he recovered as before, and he didn't remember what happened at night?"

"I thought about it, but in the end I couldn't come up with a result, the official also invited a famous doctor, but they were helpless, seeing that after the infected person had a seizure, the impact became worse and worse, the official was both sad and helpless, so he could only choose to strengthen the soil and break his wrist to save the remaining people."

"Don't be in a hurry to be pessimistic, after last night's observation, the lord of this county has discovered the mystery of their recovery during the day, and has thought of a way to crack it, but it has not been tested, and it cannot be confirmed."

"That's... I wonder when the county lord will be able to experiment? Qin Chengcheng asked with a slight hesitation.

"After nightfall, when they get sick again, it's the best time."

"Ahh Qin Chengcheng didn't expect Xu Qingyan to be so fast, and thought that she would drag on for a few days. came back to his senses and said busily: "Then I don't know what the officials can do, what needs to be cooperated, but the county lord said that it doesn't matter." “

"It's nothing, just the adults will transfer ten infected people individually, men, women, and children of all ages, between nightfall, and go to a place where no one is disturbed, preferably a clean place like a separate courtyard."

"That's fine." Qin Zhengcheng nodded: "I don't know if the county lord wants anything else, such as medicinal herbs or something?" ”

"No, this disease is not an ordinary disease, and ordinary medicinal materials are of little use to it, I will prepare what I need, as long as Lord Qin is responsible for what I just said."

"No problem, don't worry, county lord."

"That's okay, by the way, I forgot to ask the adults, I don't know when these people got sick?"

"This official doesn't know specifically, but he only knows that when he discovered this problem, the flood in this county had just receded for three days."

"Do you think this has something to do with the flood?"

"Floods? No, this disease is not contagious at all, and it is by no means an epidemic. “

"I didn't say he was a plague." Xu Qingyan smiled: "It's just that so many people suffer from a non-contagious disease at the same time, which is even more frightening." “

Most of these things have a commonality, and if you can find this commonality, you can find the source of their illness.

Only when the source is eliminated can the disease be truly cured.

"What does the county lord mean?"

Seeing Qin Chengcheng's dazed look, Xu Qingyan sighed: "Forget it, it's really a little difficult to ask Lord Qin about finding the source, it's still night, I'll ask the patient myself." ”

"The source, the county lord is looking for the source of the disease?"

"Well, what's the matter, Lord Qin knows?"

Qin Chengcheng hesitated for a moment and nodded: "When this incident first happened, the official sent someone to verify it, and later said that when the flood occurred, they seemed to have been washed into an unnamed valley outside the city at the same time. “

"The valley?" Xu Qingyan sat up straight in an instant.

"Well, they also said that there is a stone road leading to the Li River in the mountain valley, and when they were rushed in, they tightly grasped the stones protruding from the stone wall, and only then did they escape, and some people who did not catch them were directly washed into the Li River, and there were no bones."

"Where is that valley? The lord of this county wants to go and see it. “

"Twenty miles to the right of the east city gate, near the Li River, there is a mountain, just to the west of that mountain. The official also took someone to see it, but found nothing. ”

Next, the two exchanged pleasantries for a while, and Qin County Ling took his leave.

Xu Qingyan returned to the room and continued to take out the previous formation map, which was left to her by her master Dugu Bancheng. The Cultivation Realm Instrument Array is not separated, and Dugu Bancheng is the sect master of the Instrument Sect, so the formation path is naturally not weak in this aspect.

This array diagram is brief, from the lowest first-grade spirit gathering array to the super-grade time formation, there is everything. And Xu Qingyan stared at the low-grade spirit gathering array or thoughtfully.

In the outside world, the arrest order issued by the Qin County Order caused an uproar in the city, and many family members of the patients expressed strong protests against this, and various means of evading pursuit brought tremendous resistance to the arrest of officers and soldiers.

When Qin Chengcheng heard this, he was furious, and directly said: "If anyone dares to resist arrest, the whole family will sit together." “

As soon as this order came out, all the wilderness was silent.

Two hours later, after dispatching the officers and soldiers of the garrison and all the yamen, all the sick were finally arrested before sunset.

According to Xu Qingyan's request, Qin Chengcheng personally selected ten people among this group of people, and then let them be escorted to the Chengnan Courtyard alone.

When she received the report from the yacha, it was already dark, and Xu Qingyan had nothing to prepare, even Zelan and Lingxian didn't bring it, so she followed the yacha alone.

The carriage circled around the city for half a moment, and finally stopped in front of a long-abandoned house, if it weren't for the faint yellow lights inside, Xu Qingyan would have thought it was a haunted house.

Lord Qin was already waiting inside, and when he heard the movement, he hurriedly brought people out to salute.

"Why did the adults choose such a place, looking at it at night, it's quite infiltrating."

"Forgive the county lord, although there are many courtyards in the city, only this one is ownerless, the county lord said that it should be clean and no one disturbs, this courtyard covers a huge area, and the neighbors are far away, so no one will disturb them."

Xu Qingyan wasn't really afraid, she just made a joke casually, smiled when she heard the words, and asked, "What about the person I want?" “
