At noon, the street where the Literature Hall is located is full of cars and people, and this old gentleman, who usually seems to be very kind and persistent in the study of literature, has encountered an accident in his later years. It is not so much that so many people are watching because the old man was killed, but because the old man's influence in Chengguang City is so great that the first time he learned that the old man had an accident, people who had come to the Literature Hall came here.

At present, the ancient book that was lost in the Literature Hall not long ago has not been missing, but at this time Mr. Wen was killed again, if this is not a coincidence, then everything is too unusual. Before, the search for ancient books was a private matter, but now that the old man has been killed, he has to deal with this matter impartially.

The complexity of Shu Xiaoran's mood now is only known to herself, Ling Yu looked at Shu Xiaoran, who had cried to the point of losing her voice, she couldn't bear to disturb her and the old man in the last moments at this time.

However, Ling Yu's attention was now focused on the string of information next to Mr. Wen's corpse. Looking at the content displayed in the text, this is obviously not left by the old man before he died, the old man was hit in the head with a blunt object, and other parts of the body are not stained with blood, so the only person who can leave this string of information is the murderer himself.

In the corner of the lobby of the Literature Hall, the criminal police who came in to inspect found a delicate antiquity, with a small amount of blood stains on it, and the bloodstained area was slightly damaged, it seemed that this should be the murder weapon that killed the old man. However, the fingerprints on it have been cleaned and no one's fingerprints have been found.

If this string of words is what the murderer left behind after the murder, then what is his purpose in doing so, and what is the content he wants to express?

The meaning of the sentence "to a hundred is not white" is clearly to express the number "1", before from Shu Xiaoran, Ling Yu also learned that although Mr. Wenbo is a friend of Shu Xiaoran's grandfather, but the age difference between the two is also relatively large, Shu Xiaoran's grandfather is only over seventy years old, but Mr. Wenbo is already ninety-nine years old, if the content shown in the text "hundred" refers to age, the old man is ninety-nine years old this year, and it will soon be a hundred years old, will there be any connection between this?

Also, in addition to the clue of the number "1" revealed in the text, what is the meaning of a big cross next to the old man? What kind of connection is hidden behind the seemingly unrelated?

"Officer Ling."

Just as Ling Yu was thinking, she heard someone behind her calling herself, turned around, and Ling Yu saw that it was Yan Fei, who had been focusing on the news of Shu Xiaoran and the deceased just now, but she didn't even notice that Yan Fei had also followed.

"Oh, it's Yan Fei, why did you come in with you?" Ling Yu asked Yan Fei.

"It's like this Officer Ling, I was having dinner with Xiao Ran just now, and then she was in a hurry to leave after answering a phone call, her car was blocked, so I sent her in." Yan Fei explained.

"Oh, that's right."

"Officer Ling, Xiao Ran, she ......" Yan Fei was afraid that Shu Xiaoran would be stimulated by something, after all, he was also a doctor, and he knew what conditions people were most likely to have at this time, both physically and psychologically.

"Let her stay with the old man for a while, there is no way to conduct an autopsy in her current condition." Ling Yu took care of Xiao Ran, afraid that Shu Xiaoran would be stimulated by anything in the process of conducting the autopsy.

"No, Sister Ling Yu, I can do it!" Xiao Ran said after listening to Ling Yu's words. She also knows what kind of mood she is in now, but Mr. Wenbo is no one else, she must personally conduct an autopsy to find out the murderer of Mr. Wenbo.

"Are you sure you want to do this?" Ling Yu confirmed with Shu Xiaoran.

"Sure!" Shu Xiaoran wiped a handful of tears and replied firmly.

"Good!" After Ling Yu finished speaking, he found someone to record data by Shu Xiaoran's side.

Shu Xiaoran took a deep breath, and after making a slight adjustment to his state, he took the gloves from the assistant and put them on. Through his previous experience as a forensic doctor, Xiao Ran told the people around him about his autopsy results.

After about fifteen minutes or so, after the time report was sorted out, Ling Yu looked at the contents of the report:

The deceased was hit in the head with a blunt object, causing excessive blood loss and died, and the time of death is presumed to be around 1 a.m. today.

The Literature Hall closes at about nine o'clock every night, at that time the neighborhood of Chengguang City is still out of the hustle and bustle, there is no other entrance to the Literature Hall except the main entrance, the windows are tightly closed, if the murderer wants to come in, he will definitely knock on the door when no one is there, wait for the old man to open the door, and then enter the Literature Hall and kill the old man.

However, the results of the on-site investigation showed that there were no fingerprints left by the murderer when he knocked on the door, and it should have been disposed of. But the old man loves literary research in his life, and he doesn't have any enemies, the only strange thing is that a few days ago, an ancient book recording metaphysics was lost in the old man's literature hall, isn't it that the old man's death is related to this book? If not, what is the real purpose of the murderer to kill the old man?

The clues that can be reflected in the scene have almost been collected, and Ling Yu is about to return to the police station with Shu Xiaoran. The old man's body will also be buried soon, which may be the last time Shu Xiaoran will see her Grandpa Wen.

The Literature Hall has to be cordoned off until the case is over, and the piano, chess, calligraphy and paintings inside are all sealed inside, maybe these ancient literary things should accompany the old man to the last journey.

【Chengguang City Public Security Bureau】

After sending Yan Fei away, Ling Yu took Shu Xiaoran back to the police station, out of consideration for Shu Xiaoran, Ling Yu originally planned to let Xiao Ran not participate in this case for vacation adjustment. But Xiao Ran insisted on staying.

Ling Yu looked back at this case, since the old man had no enemies during his lifetime, ruling out the possibility of vendetta, of course, it would definitely not be suicide. The purpose of the murderer's murder is still unclear, and no relevant clues have been left. The only clue is a string of words left by the killer on the ground.

A few days later, there was still no breakthrough in the case, and Mr. Wen had already been buried, at the funeral, Shu Xiaoran cried like a tearful man, and at the same time, Shu Xiaoran's grandfather, who was far away in other cities, also rushed over to attend the funeral of an old friend. Shu Xiaoran cried bitterly in his grandfather's arms.

However, after the funeral, Shu Xiaoran quickly adjusted her state, she knew that now was not the time to be sad, and the most important thing was to solve the case quickly. It's just that there aren't many clues now, and there is still no progress in the case.

At noon, when Shu Xiaoran was eating, his phone rang. Shu Xiaoran saw that it was Yan Fei calling, since the last time he was separated in the Literature Hall, Yan Fei has not looked for Shu Xiaoran, he wants Shu Xiaoran to buffer for a while, but he is still more worried about Shu Xiaoran, aside from the previous relationship between lovers, as a college classmate for many years, this concern should also be deserved.

"Hello? What happened to Yan Fei? Xiao Ran asked.

"Xiao Ran, it's nothing, I'm just worried about you, ask how you are doing lately." Yan Fei on the other side of the phone replied.

"Don't worry, I'm fine, I'm fully engaged in my work now, and I won't be affected by personal feelings." Xiao Ran replied.

"Uh-huh, I'm relieved to know you're okay." Yan Fei said.

"Thank you, Yan Fei."

"Oh, what's this, they're all old classmates, anyway, it's good to know you're okay."

"By the way, my uncle has been in good health recently, and I heard that his condition seems to be getting worse." Xiao Ran suddenly remembered that he mentioned Yan Fei's father's body in the college circle of friends the day before yesterday, and he had always wanted to ask Yan Fei, but Mr. Wenbo's case was more difficult and he had been ignoring this.

"Alas, I don't know what happened a few days ago and suddenly fainted, but I have been sent to the hospital, and now I am awake, with my status in the hospital, they still take better care of my father, don't worry." Yan Fei replied.

"Well, it's fine."

"Okay, then Xiao Ran, you should be busy first, concentrate on work, and we'll talk when we have time." Yan Fei said to Shu Xiaoran.

"Okay, let's talk." Shu Xiaoran hung up the phone after speaking.

Recently, my work has been really in a high-pressure state, and I have to say that if it weren't for the phone call from Yan Fei, I might not have been able to relax for a moment, but fortunately, my state has been adjusted a lot. She firmly believes that in the end, she must find out the murderer of Mr. Wen.

In the early morning of the next day, the detective team quickly launched an investigation into Mr. Wenbo's case, but the matter was far more complicated than they imagined. Mr. Wen's case has not yet been resolved. Soon the phone on the desk in the detective team's office rang again.

This time, I received a call about another homicide, and the place of death was at a place in an English training center in Chengguang City - Way English Corner!

There was no time to pack up their things, Ling Yu, Shu Xiaoran, Qin Jian, and Chu Ming rushed to the scene of death as soon as possible. By the time they arrived, the site was in shambles, and the exhibition hall of the English training center had been completely smashed. The deceased lay flat in the hall.

The deceased was the head of the English training center, Fang Zilun, and there was a strangulation mark on the deceased's neck, which seemed to have been strangled and suffocated. After Ling Yu arrived, after seeing the situation at the scene, he asked other unrelated personnel to leave, and most importantly, Ling Yu found that there was also a string of messages written in blood on the side of the deceased: "Mr. Fang met his son Xiaorui", and similarly, there was a big cross drawn next to the corpse, and this way of leaving information was exactly the same as the previous case of Mr. Wenbo.

If the person who killed Mr. Wenbo and Fang Zilun were the same person, then what was the message left by the murderer this time?

Although the clue this time is also text, Ling Yu noticed one point, among the words "Mr. Fang met his son Xiaorui", only the words "Fang", "even" and "Rui" were described a little rougher, what does this mean? Is there something else in this message? Again, the meaning of this big cross is still not understood.
