According to the current reasoning, even if the person who stole the ancient books in the Literature Hall before was not the murderer of Mr. Wenbo and Fang Zilun, it must have something to do with this case. In other words, the purpose of the person who stole the ancient book was to commit murder, but it is not yet known what his purpose was.

After receiving this clue, the people of the detective team reorganized their thinking, in order to find out what the real reason for the murderer to create these two cases, if these two cases are linked to that ancient book, they must first understand what is recorded in that ancient book!

I saw the photos of the borrowing records on Chu Ming's computer before, and at present, if you want to know what is recorded in this ancient book, you still need to ask from people who have borrowed it before.

However, at this time, trouble came again, just when several people were looking up the relevant address information of the borrower, there were two more police calls from the office.

After Shu Xiaoran closed the phone, he told Ling Yu that he received two police calls this morning, one occurred in the Ethnic Research Museum, and the other happened in a mobile phone store, and now there was another murder, but the crucial clue about the ancient book could not be checked, so Ling Yu divided several people, Qin Jian and Chu Ming were responsible for trying to get clues about the content of the ancient book from the mouth of the person who borrowed the ancient book before, and Ling Yu and Shu Xiaoran went to the scene of the murder.

With a command, several people quickly began their work, and it can be seen that these people usually have a little noise of their own in their free time, but when it comes to work, they all exude an admirable atmosphere.

Chu Ming and Qin Jian went separately to the address of the person who borrowed the ancient book before, Ling Yu and Shu Xiaoran went to the two places where the accident occurred, fortunately, the two places where the accident occurred were located in the bustling neighborhood of Chengguang City, and they were not too far away, if the two of them walked, it would take less than five minutes to reach each other.

If the murderer of these two people is the same person who committed two crimes before, then the murderer may have taken advantage of this to the point where he was able to commit two crimes in one night!

When Ling Yu came to the family group research hall, as soon as she entered the door, the scene presented to her was a little unbelievable. All kinds of marine creatures were scattered on the ground in the broken pool, not only that, the seawater in the fish tank had been sprinkled on the ground, and it was about to dry, and the debris of the glass fiber reinforced plastic was all over the ground, Ling Yu continued to walk inside, on a desk, some research reports on marine organisms, and the classification of various organisms were clearly remembered on it.

It appears that the family group research institute was used to study a number of marine species and to classify them in detail.

Ling Yu then came to a corner, where the body was found, and the deceased was a male whose entire head had been submerged in a seawater fish tank, apparently drowned. At the same time, below the corpse, a string of conspicuous words appeared in Ling Yu's eyes:

"No matter who you come into contact with, you can't change the fate of their bloodline, unless you encounter a knot!"

Similarly, a large cross is drawn around the corpse.

It seems that this is another victim in the serial murder case, so if this is the case, will Shu Xiaoran's side also have some relevant information left around the body.

After Ling Yu thought of this, she immediately went to the mobile phone store where Shu Xiaoran was at this time. It didn't take a few minutes for Ling Yu to run to the location of the mobile phone store, she saw Shu Xiaoran standing next to the corpse at this time, the deceased was a woman, there were traces of being knocked on the back of the head, and the mobile phones in the store were also scattered all over the place, among them, the police found that there was a mobile phone with blood stains on it, which should be the tool used by the murderer when he committed the murder.

Looking around the corpse, Ling Yu also found the information around the corpse, but this time it was different from before, the clues left before were all words, but this time it was a number, and the information in front of him was in the blood, constantly meeting Ling Yu's eyes:

“9——22。”

What does this mean, there is also a big fork around this corpse, it seems that it is the same as I guessed before, the person who committed these two cases should be the same person who killed Wen Bo and Fang Zilun before. In other words, the two people who were just killed were also part of the murderer's plan to commit the crime this time, but I don't know if it was the last part!

"Xiao Ran!" Ling Yu's name is Xiao Ran.

"Sister Lingyu." Xiao Ran came to Ling Yu's side.

"When did the deceased in the mobile phone store die?" Ling Yu wanted to verify it further.

"It's been tested just now, it's four o'clock in the morning." Xiao Ran replied.

"Okay, you go to the family group research institute and find out when the deceased died." Ling Yu said to Shu Xiaoran.

"Well, I'll go." After Xiao Ran finished speaking, he ran towards the research institute of the family group where Ling Yu came just now.

After that, Ling Yu looked at the message left by the corpse, and recalled in her mind the information she had just seen at the Institute of Ethnic Studies. Try to deduce what these two strings of information mean.

After a while, Ling Yu's mobile phone rang, and it was Shu Xiaoran who called, and it should be news from the autopsy report over there.

"Hello? Xiao Ran. ”

"Sister Ling Yu, the test has come out, this deceased really died at three o'clock in the morning!"

Ling Yu seems to have gotten the confirmation she wanted:

"Okay, notify the people over there, protect the scene, extract useful things and close the team!" The clues that should be obtained at the scene are almost done, and the next thing to do is to return to the police station, analyze the two cases that just happened, try to connect them with the previous two cases, and see if there is any suitable breakthrough.

【Chengguang City Public Security Bureau】

Chu Ming and Qin Jian haven't come back yet, there are only two people in the office, Shu Xiaoran and Ling Yu, the first time they came back from the scene, Ling Yu developed all the photos taken at the scene, pasted them on the whiteboard, and began to investigate.

The first is the deceased in the Ethnic Research Center, the information shows that the deceased's name is Wang Kun, male gender, age 43 years old, head of the Occupational Ethnic Research Institute, the cause of death is drowning, and the time of death is around three o'clock in the morning; The second is the deceased in the mobile phone store, the information shows that the deceased's name is Zeng Xiaoling, gender female, age 35, professional mobile phone store owner, the cause of death was excessive blood loss in the brain after being hit with a blunt object, and the time of death was around 4 o'clock in the morning.

Next is the information left by the two deceased, before returning to the police station, Ling Yu has been thinking for a while, and there is some idea in his mind. Let's take a look at the message left in the Ethnic Research Institute: "No matter who you come into contact with, you can't change the fate of your bloodline, unless you encounter a knot!" "In the previous two cases, the key to decryption was the location and number, and if the murderer this time was the same person as the previous two cases, he would inevitably leave clues in this form, which may also be carried out according to what was mentioned in the ancient books.

If the mystery is still a number this time, the key to decryption is the location, the Institute of Ethnic Studies? Coupled with the information revealed by the text, no matter who you come into contact with, you can't change the fate of their bloodline, unless they encounter a knot.

"Sister Ling Yu, do you see something? What is bloodline, and what are the knots? Shu Xiaoran was a little puzzled, and he didn't have a clue at all.

After a while, Ling Yu spoke: "If the mystery is a number, the meaning of this sentence becomes, no matter who you contact with, the nature of this number will not change, unless you come into contact with something special, it will change a little, is that right?" ”

Ling Yu continued: "Xiao Ran, do you think, a number, no matter who you come into contact with, it will retain its original nature, what will you think of?" Ling Yu seems to have an answer.

"It's an even number!" Shu Xiaoran seemed to understand something.

"That's right, that's the number..."

"It's 2!" Shu Xiaoran replied in front of Ling Yu.

"Yes, that's it, no matter which number 2 is multiplied with, the final result must be even, 2 itself is an even number, therefore, he is still an even number in the end, and he can't change his nature, then the node should refer to the number 0, and the final result of multiplying 2 and 0 is 0, although 0 is also an even number, but it is a special even number, so what this string of words wants to express should be the number 2!" Ling Yu replied firmly.

"What about the clues in the mobile phone store? What is left in the mobile phone store is not a clue, but a string of numbers 9-22." Xiao Ran then asked Ling Yu.

The corners of Ling Yu's mouth raised slightly: "I can see this in the mobile phone store." ”

"What is it?" Xiao Ran wanted to know.

"What do you think of in a mobile phone store?" Ling Yu is prompting Xiao Ran.

"Mobile phone store?" Shu Xiaoran finally muttered to himself, and then closed his eyes, as if to verify his conjecture.

"I know,If the mobile phone store is the key to decryption,The most important word must be the mobile phone,There is a dash between several numbers,The front of the '9'If you look at the nine keys on the phone,Then the following '22' represents the meaning of pressing the second key twice,According to the pinyin above the nine keys,It is likely to press out'ba',So,The final content of this string of information is the number '8'!" Xiao Ran was testing her reasoning with Ling Yu.

"Yes, that's the message left in the phone store." Ling Yu is sure of Shu Xiaoran.

After the two cases, they now get two more numbers "2" and "8", plus the previous two numbers "1" and "4", and now they get a total of four numbers, but what is the connection between these four numbers? I'm afraid this will not be clear until Chu Ming and Qin Jian get some relevant clues on the ancient books from the people who borrowed the ancient books before.

"1", "4", "2", "8", what do these four numbers mean, and the time of death of the four deceased people is one o'clock in the morning, two o'clock in the morning, three o'clock in the morning, and four o'clock in the morning, and these times are all their birth times, as well as the fork next to the four corpses, these mysteries are now constantly wandering in Ling Yu's mind, impacting Ling Yu's brain.

"Jingle bell!"

At this moment, Shu Xiaoran's mobile phone rang, it was Yan Fei calling!
