Return to 1983 and be a detective

Kaibing County is indeed very small, with only three oil mills in one county.

Among these three oil mills, two are slightly larger and mainly produce rapeseed oil.

After squeezing the rapeseed oil, you can fold it into oil cakes, which can be used to make nests and lure fish very efficiently.

After pressing the tea seed cake, it seems that it can only be used as fertilizer.

So the three of them, Xu Shan, went directly to the oil mill that specialized in tea seed oil extraction.

This oil mill uses an old waterwheel. The waterwheel is placed on a fast creek. The water drives the wheels and then drives the hammer, which keeps squeezing oil.

This method is quite old and quite inefficient, but it gives Xushan a special feeling. Sometimes, although modern industry brings rapid development, many humanistic feelings are also lost in the process of development.

Especially in later generations, after the emergence of many artificial intelligences, many people seem to have been alienated into the existence of tool humans, unable to have fun in work and life.

Now seeing this ancient waterwheel and ancient oil mill, Xu Shan has another feeling. In fact, there is no need to run forward in our lives.

The owner of this oil shop is a young man who is quite handsome, but unfortunately one of his legs is a bit disabled.

He is the fifth generation descendant of this oil mill, and his name is Fu Cuishan.

Hearing Xu Shan ask about the customers of this oil mill, Fu Cuishan recalled it and slowly reported all the customers who came to his place to press oil in the recent period, as well as the tea seed oil brought by these oil press customers. Number of kilograms.

Xu Shan asked Ma Qing to write down all these customer lists. Ma Qing also knew the memory palace and remembered it every time he listened to it.

Then I turned around and immediately discovered an important clue.

That was among the five members of the exterminated family, the pregnant woman had come here to extract oil.

In other words, the tea seed oil used as ignition at the fire scene was most likely from the victim's own home.

This brings up another question: What kind of person would lock this family in the house, light a fire with their tea seed oil, and burn down their house?

How cruel this is, what kind of hatred or resentment is this.

Ma Qing and Gu Dahai knew that the clue was broken at this point, so they couldn't help but feel a little disappointed.

But Xu Shan is very optimistic: "You don't have to be so disappointed, at least we have eaten a lot of delicious food these days."

"But this case has to be solved, otherwise we will eat and drink for free every day and it will become a public trip." Ma Qing said.

Xu Shan knocked him on the head: "Correction, the meals these days are all paid for by me, not at public expense. In addition, it is not that we have gained nothing, at least we can eliminate one wrong answer."

"But this doesn't seem to be making any progress for us in solving the case."

"You are wrong to think so, why not? Think again, why are we here this time? To investigate the source of this tea seed oil, haven't we already investigated clearly? They bought it themselves."

"So what? The oil you squeezed by yourself can only mean that the oil is from their home and was taken by the murderer. It seems to have no effect at all on determining who is the murderer."

"It really has no effect at all? Dahai, you say."

Gu Dahai frowned when he was suddenly named, but soon relaxed: "Ma Qing, what you said is wrong. Master Xu means that now that we have found the source of the ignition, in fact, it is difficult to judge Who the murderer is helps a lot.”

"What help?" Ma Qing was puzzled.

"It seems that you just memorize something every day. Memorizing is useless. You still have to think." Gu Dahai said with a little ridicule.

"Okay, you can think and explain it to me."

Ma Qing was teased and a little angry.

"Okay, let me tell you this. Judging from the fact that the tea seed oil used in the fire came from the victim's own home, it can be explained that the murderer probably did not commit the crime in advance. If it was a premeditated crime, Then he will definitely bring some combustion aid or other things."

"What you said makes sense, is there anything else?"

"Of course, we can't rule out that this is a premeditated crime, but the premise is that the murderer is very familiar with this family. At least he visited the family's kitchen during the time he arrived at the scene in August. Is that right, Master Xu?"

Xu Shan nodded with satisfaction: "The analysis is good. This analysis has given us a clear direction. At least if we investigate from this direction, we are likely to gain something. Let's go. Li Yanzi and the others will come back later. Let's follow them. With a pair of clues, important facts of the case should come to light.”

Soon everyone gathered together, and the place where they gathered was very strange, it was a restaurant.

Xu Shan specially requested a private room. In the hotel, everyone chatted about the case while eating, which was quite relaxing.

Once everyone summarizes their work progress, they will really gain a lot.

Li Yanzi's side is responsible for investigating interpersonal relationships.

She said that they found out that the male owner of this family, a pregnant man named Hong Xinyao, had some problems with his style. It was said that he had broken shoes outside. Later, when the man from the family came back, he even got into a fight. It was for this reason. , their family moved to the city.

The person on Su Jing's side who was responsible for investigating this guy's financial situation also got an important clue, that is, the male owner Hong Xinyao had always been an ordinary tea farmer. Although the Longding tea in Kaibing County was very It's valuable, but tea farmers don't have brand awareness yet, so they haven't been able to sell it at a high price.

Then one day, around August, a few strange people came to Hong Village where Hong Xinyao was. These people were obviously not from this province. I heard that one of them was carrying some Northeastern food. Accent, they rented the empty house of Hong Xinyao's family and lived in it, and then they acquired some special things here.

What they want is a fungus from the soil called a ghost pen.The price offered is very high.

There were also some people in the village who were interested. They tried to find it and sold it to them. As expected, they made a lot of money. Among them, Hong Xinyao was the most active. He was the first to know what these people collected. As their The landlord, not only did he collect a lot of rent, but he also found a lot of mushrooms called ghost pens for them and made a lot of money.

Hearing the name ghost pen, Xu Shan probably had a guess in his mind. This kind of thing is actually a poisonous mushroom. There are very few ghost pens with strong hallucinogenic properties. This kind of thing is not suitable for ordinary people. It is very harmful, but for practitioners, it may be a very good elixir that can greatly improve people's practice in a short period of time.

So those who look for these ghost pens are either ordinary people with evil intentions or practitioners.
