Return to 1983 and be a detective

From Hong Dayong's confession, Xu Shan found some clues, so he found Hong Dayong's brother-in-law, Xiang Huaqiang.

This Xiang Huaqiang looks quite energetic, but he is deaf. It is said that he caught a cold when he was young and was given antibiotics, which made his ears deaf.

So talking to him is more difficult.

Thanks to Fang Yongjun's mute language skills, he was able to speak and gesture with him, and was able to get the complete confession out of his mouth.

Xiang Huaqiang confessed that his brother-in-law originally entrusted him with guarding this warehouse. Later, because two old cousins ​​came, he had to give up this position to the two old cousins.

He turned into a gatekeeper.

Don't look at it, it seems that the door job is quite easy.

But there is a lot less oil and water. When he is looking at the warehouse, if he is hungry, he can steal some cans to eat and take some home.So even though he was deaf, many people came to propose marriage to him.

Now that he has become a gatekeeper, this invisible benefit is no longer available. In addition, his brother-in-law Hong Dayong is very stingy and does not take special care of him, so he went to find those two old cousins. In the end, the man among the two old cousins ​​reached a cooperation with Xiang Huaqiang, and he could help Xiang Huaqiang get some cans out.

This kind of cooperation made the relationship between the two of them very close. Xiang Huaqiang also knew that this guy named Lao Cao was originally a teacher and was good at calligraphy. In addition, the beautiful woman Xiao He was good at burning. vegetable.

Xiang Huaqiang often goes to their place to eat and drink some wine.

Until one day, this old Cao suddenly died in the warehouse. It is said that he died on top of a pile of cans.

This made Xiang Huaqiang very worried and a little guilty. He always wondered whether Lao Cao accidentally fell to his death because he was holding cans for him.

Because Lao Cao's legs and feet are not very convenient, but if he wants to take cans, he has to go to the top, which can easily lead to accidents.

Hong Dayong didn't care about this and asked Xiang Huaqiang to take Lao Cao's body to the mountain and bury it.

After burying Lao Cao, Xiang Huaqiang still often went to Xiao He. His intention was to take care of Xiao He for Lao Cao, and Xiao He basically accepted Xiang Huaqiang. Gone together.

However, Xiang Huaqiang proposed several times that he wanted to marry Xiao He, but Xiao He did not agree. This made Xiang Huaqiang very angry and ignored Xiao He for several days.But then he thought about it and it was not impossible to maintain the status quo. However, when he went to find Xiao He again, he found that Xiao He was missing.

Later, it was he who fished Xiao He out of the pond and took him to the mountain to bury him.

He felt that Xiao He must have missed Lao Cao and finally chose to commit suicide, so he took it upon himself to bury the two bones together.

Xiang Huaqiang's confession is quite complete, and there should be nothing to hide.

After all, if he really wanted to hide it, he could not tell anyone about his relationship with Xiao He, because this relationship could easily be associated with love murder and make people associate Lao Cao's death with Xiang Huaqiang.

According to Xiang Huaqiang, all this seems reasonable. Lao Cao slipped and fell to his death, and Xiao He died of love.

But in this case, why did Xiao He develop another relationship with Xiang Huaqiang before his death?Isn't this superfluous?

This confused Xu Shan.

It is estimated that only by unraveling this point can he understand the truth of the canned human flesh case.

He asked Fang Yongjun to ask again: "Where are the clothes Xiao He is wearing? Why haven't they been fished out of the pond?"

This is indeed very strange. Both corpses seem to be without clothes.

Xiang Huaqiang blushed and said, "It's not because I thought these clothes were quite good, so I took off their clothes and gave them away."

Well, this guy is really a bit unscrupulous.

Those who were wearing the clothes he sent out would not know how they would feel if they knew that the clothes were stripped from the dead.

I guess Hong Dayong knew this brother-in-law very well and knew that his hands and feet were dirty, so he transferred him from the warehouse to the guard position.

Waiting a moment, Xu Shan suddenly realized another problem: "Where are the things in their house, have you taken them away?"

"Are you talking about those guys they brought? I didn't take that, oh no, I took a ledger..."

"What are you doing with the ledger?"

"Ahem, isn't that right? Besides drinking some wine, I also like to play cards. So I owe a little money. I borrowed money from Lao Cao before, and Lao Cao was very loyal and lent me a lot of money. Money. I never had the money to pay back, and then he took the account book and urged me to pay it back.

Later, when he died, I thought that the debt would be wiped out after death, so I stole the account book. "

Xu Shan was speechless on the spot.

Doesn't it mean that when the debtor dies, the creditor will no longer pursue the debt?

If Huaqiang performs a reverse operation, if the creditor dies, his debt will be cancelled?

"Where is this ledger now?"

Xiang Huaqiang did not hesitate, and directly took out a work notebook he carried with him and handed it to Fang Yongjun, who in turn handed it to Xu Shan.

Xu Shan opened the work notes and looked at them carefully. He found that the writing on it was quite neat and beautiful, reaching the level of a calligrapher.

It does say how much money so-and-so owes.

In addition to Xiang Huaqiang owing him money, it seems that Xiao He's original wife and some workers in the kiln factory also owe this old Cao a lot of money.This is no wonder why when he was with Xiao He, he only received a beating.It's no wonder that the two of them disappeared. Those people had no intention of looking for him at all. They must have the same idea as Xiang Huaqiang. If people die in the opposite direction, their debts will disappear.

Xu Shan flipped through the pages, and he found that in addition to accounting, there were some password-like records on the account book, such as four-digit numbers like 0135, 0210, and 2110.He thought about it for a while and then handed the account book to Fang Yongjun: "What do you mean by these numbers?"

Fang Yongjun took these numbers, considered them, and asked Xu Shan: "Xu Shan, are these codes? If you want to know these words, do you need to decipher these codes?"

"I think so too. Look at the series of numbers written on the last page. It's a clear statement. I guess as long as this series of numbers is cracked, we can figure out how this guy died. "

"But looking at these digital passwords, I always feel that this password needs a corresponding code book to crack it. Where can we find this code book?"

Fang Yongjun's doubts were also Xu Shan's. This simple string of numbers should be the page number in a book, followed by the serial number of the word. It is a first-level cipher text that can be easily cracked.

The real difficulty lies in how to find that codebook and find the corresponding words.

"If you ask this deaf man again, ask him if he has read what books this old Cao often reads."

Fang Yongjun didn't understand why Xu Shan called Xiang Huaqiang "Deaf Five", and muttered: "He is deaf, but he doesn't seem to be the fifth at home, so why call him Deaf Five?"

Naturally, Xu Shan would not explain, but just urged Fang Yongjun to ask quickly.

Xiang Huaqiang thought for a while and replied: "He seems to have a shabby book called Cai Gen Tan. I can't understand the words in it, but he likes to read it. He told me several times that the great man once said that you can chew the vegetable roots. Everything can be done. It is said that this Cai Gentan contains principles of life and dealing with things. If I have nothing to do, I can learn more, which will be good for me. "

"What now? Where is the book?"

"I don't know about this. I went there late, and it seems that all his things were taken away. I don't know if they were sold as junk or collected by others."

There is definitely something going on here. Xu Shan and Fang Yongjun looked at each other. It seemed that Cai Gentan was Lao Cao's code book. Moreover, the publishing houses of this era were far less developed than later generations, and there could not be so many different versions. Basically, except for reference books like Xinhua Dictionary, most books will not change editions every five or ten years.What's more, this Cai Gen Tan is actually an unpopular book. At least now, it is absolutely unpopular, and it is impossible to have many versions.

So Xu Shan and the others realized that as long as they found a Cai Gen Tan, they could unlock the code and know the truth behind Lao Cao's death wish.
