When everything was ready on Director Liu's side, a message came from Officer Zhang's side that they had made a new discovery there.

So far in the Meishan case, the first valid witness has finally appeared, and this valid witness took the initiative to find Officer Zhang that day and told him that he knew some things back then

At first, Officer Zhang and the others didn't believe this person's words, and even doubted the origin of this person, because there had been an undercover agent on the mountain before.

Now no one can say for sure that these people may have been sent by someone else, and later several people made some inquiries about this person with vigilance.

Officer Zhang was surprised to find that this person might indeed be an eyewitness back then.

But why did such a big event happen in such a big beautiful mountain, but there are very few people who know about it now, and those who know it are either already dead or unwilling to say it.

Why did this person take the initiative to stand up at this time and tell the police some things back then?

After the questioning of Officer Song and Officer Li, it was later learned that this person used to be a stickman in the mountains, who had gone up the mountain many times to cut firewood, and sometimes hunted some small animals back.

At that time, because the family was poor, they would often take off the skins of animals and sell them in the market.

But once he found something in the fur of an animal, and found a note in it, which was yellowed, and when it was opened, there was nothing written on it, which the man thought was very strange.

Later, this person didn't throw away the note, but found a random place to put it away, but by chance, he suddenly thought of this note again, and the reason why he remembered this note was because of the arrival of Officer Zhang and the others.

It stands to reason that these animals that they hunt and kill have been active in the mountains for some years.

It was not surprising that something was found in their fur, but why was it a note, and there was no writing on it.

Later, he handed the note to Officer Zhang, who also took the note and studied it carefully, although it seemed that there were no words.

But Officer Zhang suddenly remembered a previous method, and made some water by himself, and smeared out the words on the paper little by little, only to see that it was written: 繁...... Kill......

Officer Zhang and the others were stunned, and then they asked the villager where they had caught the animal, and the villager recalled that the animal had been captured in the vicinity of the place where they now found the corpse pit.

It stands to reason that there should be no animals, because there is no vegetation growing in that place, and animals live on food, and if there is no food and water, animals generally do not settle there.

When the villager said this, Officer Zhang thought of something, and they found that there was no lush grass growing near the corpse pit, but the grass in other places had been growing vigorously.

Could it be that there is a problem with the soil there, but they are all in the same place and in the same weather, and even if there is a sudden change, then the least change should be the same. But why is there almost no grass growing around the grave?

Officer Zhang suddenly put this person there and left Officer Song and Officer Li to guard it.

As for himself, he hurried back to the vicinity of the corpse pit at the scene of the crime, he only looked at the soil around the corpse pit, and heard the sound of birds coming from not far away.

Officer Zhang remembered that on the first day, when the policemen first went up the mountain, they initially thought that they had a serious reaction to water and soil adaptation, everyone vomited and diarrhea, and sometimes there were red rashes on the skin.

At the time, I thought it was a mosquito bite in the mountains, but now it seems that everything is not so simple.

As if he had figured out something, Officer Zhang immediately called Director Liu to report to them, telling them that he could start with the terrain around the corpse pit, which had obviously been treated over many years.

And why this man keeps the place without trees for many years, and even the animals generally don't want to come, must be to make people less likely to find it, because people often go to the mountains to cut wood, and catch animals or take herbs.

Officer Zhang couldn't help but shudder when he thought of this, but he felt happy again after a while.

The reason why Officer Zhang was frightened was because he thought that this person was very thoughtful and tried to eliminate all possible possibilities, so the possibility of the crime scene being discovered would be greatly reduced.

But how could he have imagined that after so many years, an animal would suddenly come to this place, and it happened that he would be chased here by a stickman.

And all this is very likely that the murderer did not expect, of course, it is very likely that the murderer guessed that this place would be discovered sooner or later, maybe he was already fully prepared.

But no matter what, Officer Zhang is really not very happy, because these days, he finally has a clue about the development of the case, and it is also the result of their hard work for a period of time.

When Officer Zhang looked at the group of policemen under him, he remembered how they vomited and diarrhea when they first went up the mountain. Now he can't help but feel a little excited, because he knows that there is a lot of poison in the air or environment around him.

It's just that the dose of this poison is very small and not enough to make people deadly, so for many years around here, not only do not small animals escape, but even plants and trees basically do not grow.

But if the murderer wants to maintain a place like this all the time, then it will definitely not be a day or two, and it will definitely persist for many years.

Officer Zhang later thought that if he really couldn't do it, he first asked Director Liu to see if he could send an expert with geological considerations to test the soil composition and the surrounding air.

He believed that something would be discovered here, and Officer Zhang believed very much in his feelings, and he could not go wrong this time.

Because he had already suspected it before, the little policemen who went up the mountain with him were all young and strong.

And all of them are athletic, how can they simply vomit and diarrhea when they encounter water and soil, and even dehydration, and even walk unsteadily.

At that time, I was still thinking that there should be a certain degree of adaptation to water and soil, but the little policemen at that time seemed to have far exceeded that degree.

But at that time, his attention was all focused on these cases, and he had been looking for the source of these bones and the traces found on the bones, and he did not turn his attention to this aspect at all.
