Following the list given by the night scene, Lu Yunqian began to visit the poisoned people door-to-door, because she had already bought a disease detector from the small treasury of the system, so what kind of poison those people had, she knew at a glance that it was just a very ordinary food poisoning, which would cause vomiting and diarrhea for a day or two, and then it would be nothing.

In the process of visiting, Lu Yunqian found that those poisoned families all lived in the same area and felt very close to a certain shop, so Lu Yunqian recorded one by one which store they bought the salt from, and the result was that it was all in the shop that Zhang's father gave to Zhou Lang.

In this way, Lu Yunqian understood what kind of process this poisoning incident was, it was nothing more than that in the store where it was given, it could be poisoned unconsciously, and then the Zhang family bought some ordinary people, bought salt and pretended to be sick to bring up the rhythm, and then the group effect, some people were convinced.

The final result is nothing more than that no one dares to buy the Zhou family's salt anymore, after all, it is a matter of life, and everyone would rather believe it than dare to take risks.

After investigating all this, it was almost dark, and Lu Yunqian planned to go home first.

Along the way, Lu Yunqian was thinking about countermeasures, if he directly went out with everything he found, then I'm afraid no one would believe it, after all, the Zhang family has been monopolized for so many years, even if everyone has some complaints about it, they will not believe that people will poison it.

In the end, there is no clear evidence, reasoning is always just reasoning, and for those who are already convinced, they will not only not believe it, but will also feel that they are making excuses to shirk responsibility.

Thinking of this, Lu Yunqian couldn't help but feel a little depressed, the case-solving technology of this era is really difficult compared to modern times, so he knows the truth, but sometimes he still can't bring the real bad guys to justice.

When she returned home, Zhou's mother saw that Lu Yunqian was the only one and didn't bring Zhou Lang home, so she started crying again, but Zhou's father was much calmer, and he could calmly ask Lu Yunqian what was going on now.

Because he was worried that Zhou's father and Zhou's mother would make a move to startle the snake, Lu Yunqian did not tell them what he found, but only told them that he had asked the Overseer to take care of Zhou Lang, and his side was also stepping up to find out the truth, so as to restore Zhou Lang's innocence.

"How long will it take to investigate? Lang'er has been imprisoned, I'm really afraid that he will be bullied!" Zhou's mother said worriedly while wiping her tears.

"I'm trying to figure it out, we all know who did it, but we don't have any proof. Lu Yunqian didn't have the heart to comfort Zhou's mother, she just frowned and said her worries.

As soon as she heard this, Zhou's mother instantly turned from sad and angry to angry, and she said with anger on her face: "Their Zhang family dares to put my son in prison, and I don't want their daughter to have a good time!"

Saying that, Zhou's mother immediately rushed towards the courtyard where Zhang Ping was, as if she was going to kill someone.

Mother Zhou and Lu Yunqian hurriedly stopped Mother Zhou, Lu Yunqian explained vigorously that she couldn't startle the snake, but Mother Zhou just didn't listen, and in the end, Father Zhou yelled angrily: "Old woman, do you want to kill the second child?"

Being yelled at like this, Zhou's mother regained her senses, and then burst into tears and cried bitterly.

Lu Yunqian really couldn't stand such a scene, and felt like she couldn't think, so she said categorically: "Father and mother, don't worry, I will definitely rescue my uncle!"

After finishing speaking, Lu Yunqian went back to the room alone, she needed to think about what to do next.

"Is there the same poison in the small treasury?" Lu Yunqian asked the system 1203 as soon as he returned to the room, although Zhou's mother's impulse was stopped just now, it reminded Lu Yunqian, making her think of a good way to solve this matter.

"Host, what do you want this for?" System 1203 asked, somewhat confused.

Lu Yunqian immediately replied without thinking about it: "I naturally want to treat the other way and put the same poison into the Zhang family's salt shop, I just want to tell everyone that there is nothing wrong with the Zhou family's salt field, it is completely because of the problem with the Zhang family's shop." ”

System 1203 couldn't help but be a little dumbfounded, and it asked in a daze, "But won't this poison cause harm to people?"

I didn't expect that system 1203 was so inflexible, Lu Yunqian said angrily: "The effect of that medicine is to vomit and diarrhea for two days, to put it bluntly, it is a detoxification effect, but those people who are scared are all soldiers, not to mention that you have a way? This is your upgrade task!"

Hearing this, the system 1203 doesn't feel that there is any problem, not to mention that this is still for its upgrade task, so naturally there is nothing to say.

So System 1203 began to look for the poison that Lu Yunqian wanted in the small vault, and finally looked for a long time before saying: "Host, there is no identical poison, but there is a similar effect, do you want it?"

"Why is your little vault as unreliable as yours?" Lu Yunqian thought that the small vault of system 1203 had nothing, but there was no medicine, and she couldn't help but complain a little disappointed.

"Do you want the host? If you don't, you can just prepare some pills yourself!" System 1203 said unconvinced, and at the same time, it didn't forget to remind Lu Yunqian: "The host still has fifty experience points on credit, I don't think you should continue to take credit, you can work hard and match it yourself!"

Lu Yunqian didn't expect that she just said a word, and the system 1203 gave her so many sentences back, so she said very dissatisfied: "Listen to me or listen to you?

"It depends on how many hosts there are, and a hundred experience points can be used for about two stores. System 1203 said truthfully.

After listening, Lu Yunqian couldn't help but be silent, the Zhang family has not ten salt shops in Jinzhou, but also eight, doesn't that cost her four or five hundred experience points? It is really a bit extravagant, especially when she thinks of her previous experience of all kinds of hard-earned experience points, it makes Lu Yunqian feel that it is not worth it.

After perceiving Lu Yunqian's mental activity, System 1203 said approvingly: "What the host said is right, in fact, you have already bought the prescription at that time, and you go to the Zhou family's medicinal herb shop to make your own pills, and it will not be wasted, it is much easier than you to earn experience points." ”

"You're right, I really can't take credit anymore, lest I have no experience to buy a baby next time I encounter danger. ”

After weighing the pros and cons, Lu Yunqian nodded, she also felt that it was worth it, the poison of the Zhang family was made by herself, and there was no reason why she couldn't do it. The heart was moved and immediately acted, so Lu Yunqian did not stay for a moment, and immediately rushed to the Zhou family's medicinal herb shop.
