Shangguan Yinling opened the box, and inside was a few letters with a lot of money and personal contacts.

He opened it, and he was blown away by what was inside.

It turns out that there is a person behind him who has been using Qian Dayou to control the rise and fall of salt prices in the capital, so as to make huge profits.

The person behind it is very secretive, and there is no payment on every letter.

"Where did you find this?"

"I found it from a salt farm with a lot of money."

Since discovering that Qian Dayou's family had been killed, in order not to miss any useful information, the brothers of their special case department went to all the salt farms under Qian Dayou's hands, and finally let him find Qian Dayou's correspondence with people in a salt village.

A few letters came and went, and the last thing mentioned was more than a month ago.

And judging from the narrative tone of the last letter, Qian Dayou seems to have not negotiated with his business partner, which led to the termination of the cooperation.

It is very likely that it was because Qian Dayou was no longer at ease under the control of this person, which made him angry and angry, and simply killed Qian Dayou's family.

But if that's all there is to it, why bother to leave bloody handprints on the wall?

The bloody handprints are really a bit ridiculous, they painstakingly printed the bloody handprints on the wall one by one, but in fact, it can be seen at a glance that the bloody handprints were printed by the killer later, at most, it played a terrifying role, expanding the impact of the murder of Qian Dayou's family, and other than that, there is no other meaning.

Could it be that the murderer just wants to make this matter bigger?

But if you really seek revenge, or if the business is not negotiated for malicious revenge, just kill someone, there is no reason to print a bloody handprint again.

Since they have printed bloody handprints, it means that the killer behind this wants them to investigate deeply and find out that there are some unknown things about Qian Da.

Lu Li took the letter in Shangguan Yinling's hand and looked at it generally.

Judging from the first letter, Qian Dayou has been cooperating with this person for some time, although Qian Dayou is not a powerful person, but with his own businessman's mind, he dominates the salt village market in the capital, and the salt village under his command accounts for about eight-tenths of the entire salt village in the capital, and there is no problem for the person who wrote the letter to cooperate with Qian Dayou to plunder money.

However, since Qian Dayou can cooperate with him, this person will definitely not be a simple commodity, at least he is either rich or powerful, or he is a wealthy businessman in the capital, or a court official with power in hand.

Qian Dayou is not short of money, and he should not cooperate with wealthy businessmen, not to mention that in this correspondence, Qian Dayou has always been quite flattering and respectful to the other party, this person is very likely to be a court official, and even a powerful minister with a large official position.

If this matter really has something to do with the killing of Qian Dayou's family, in short, if it was really the person who exchanged letters with Qian Dayou who killed Qian Dayou's family, if he didn't want their cooperation to surface, and the burial of the corpse was almost the same, how could he blatantly leave so many bloody handprints to attract everyone's attention?

"The person who killed Qian Dayou's family should not be the person who exchanged letters with Qian Dayou."

Shangguan Yuling frowned slightly and looked up at Xu Yun.

"What enemies did Qian Dayou have during his lifetime?"

"This ...... My lord, to be honest, Qian Dayou had a lot of enemies during his lifetime. ”

Don't talk about ordinary enemies, even the kind of enemies who hate them to the core, at least there are seven or eight people.

Qian Dayou didn't do a good thing when he was alive, but he did a lot of things that hurt people out of conscience, not to mention that he really had an enemy who hated him to the core, and even the people in the city hated him very much.

This person has offended too many people, and there are many enemies, and everyone may be the murderer of his family, so it seems that the difficulty of the investigation is too great.

"First list the most hatred and suspicion, and bring everyone to the Special Case Division."

"Yes."

After a while, the people who had a deep enmity with Qian Dayou knelt down in the hall.

Shangguan Yuling lowered his eyes and looked at the expressions of these people, they did not have any weakness of heart, but had a happy look on their faces.

That is, in front of Shangguan Yinling, they also restrained a little, otherwise they might have to go to the restaurant to celebrate together.

"Where were you all last night?"

"Back to my lordship, at home, at that time, I had already rested, and everyone in the house could testify."

"Back to the adult, the villain is in the Suwen Building, and the flower girl in the Suwen Building can testify."

"Back to my lord, the villain drank with the same person last night, got drunk, and lay down in the tavern all night, and the second child in the tavern can testify."

Good guys, all of them have alibis.

"I heard that you all have a deep enmity with Qian Dayou?"

"My lord, we don't like to tell lies, to tell the truth, we have all been harmed by Qian Dayou, and we have been doing business with Qian Dayou in those years, and we have been stumbling by him, and we do hate Qian Dayou very much, because Qian Dayou, the foundation of my ancestors has been lost once, and it has not been relieved." These people are upright and don't tell lies, "Qian Dayou was killed, and we are very happy in our hearts, but it is really not our doing." Although we hate money, we can't do such a disgraceful act. ”

"Well, you go back first, and wait for the summons at any time."

"Master Xie."

After sending away several batches of Qian Dayou's enemies, Shangguan Yinling only felt a headache.

There are more than 20 people in a family who can kill all the money in one go, and the killers they are looking for are all strong in martial arts, even if they buy murderers, there is no such professional killer organization, even if there is, the silver taels needed to invite twenty killers with strong martial arts are not a small amount.

Now they can suspect that the killer may not be an ordinary person, or that this person is powerful and has a group of killers with strong martial arts under his hands.

At present, it is impossible to find out more useful information from the investigation of Qian Dayou's enemies, so it is better to turn around and carefully investigate the letters that have dealings with Qian Dayou.

Regardless of whether the money was hidden or someone deliberately let them find out, those letters exchanged will definitely be of great help to the progress of this case.

"Xu Yun, you go and find the list of all the relatives and workers in Qian Dayou's family."

Qian Dayou can also be regarded as a large family in the capital, most of the people in the family should have deeds and documents, starting from these people, you may be able to find clues about Qian Dayou's dealings with people.

Xu Xingzuo was very fast, found the list of personnel, the transfer documents and the identity deed from Qian Dayou's house, compared them, and found a remarkable thing.

"My lord, there are not only twenty people killed in Qian Dayou's mansion, but twenty-one!"

"Where else is the other person at the moment?"
