heart poison

"That's too inefficient." Liu Zhiqin shook his head, "It's very troublesome to deal with Internet companies. If it's a local or provincial company, it's okay to say that they will cooperate with the public security organs to investigate the case to a certain extent, but Weibo is not in Los Angeles. Not in Hanoi. We need to investigate many and complicated things now, and there is no strong evidence. Under normal circumstances, Internet companies will refuse to cooperate on the grounds of protecting user privacy, so some unconventional means are used. Once we have an idea, we will take the official route."

Hua Chong understood, and lightly patted Liu Zhiqin on the shoulder, "Is this your old profession?"

"Almost." Liu Zhiqin smiled, "By the way, Team Flower."

"Ok?"

"Pour me a glass of water, please?"

"White water or chrysanthemum tea?"

"Let's just use plain water." Liu Zhiqin said, "You don't want to boil water, and I don't want to drink chrysanthemum tea brewed in cold water."

A quarter of an hour later, Hua Chong put the chrysanthemum tea brewed in boiling water on the small table in the lounge.

Liu Zhiqin: "Hey, is the sun coming out from the west?"

"Who says I won't boil water?" Hua Chong nodded, "Drink it when it's cold, don't burn it."

The two lines of the serious crime team were parallel, and they did not stop investigating Tang Su and Xu Yujiao's real-life relationships, but the deeper the investigation, the more the team members felt that they had reached a dead end.

"No one has any doubts." Qu Zhi slumped on the seat, holding the iced black tea in both hands, his eyes glazed over, "How can this murderer be so good at hiding?"

"Tang Su and Xu Yujiao's bags and mobile phones have not been found so far. Sanghai and Qiu Dakui have never admitted that Xu Yujiao's death was related to them." Zhang Mao said: "As for the blood on the hammer and fruit knife, no matter how you ask, their answers It's all 'don't know'. Flower team, I don't think they are pretending."

"Then Tang Su and Xu Yujiao are really jealous by strangers on the Internet?" Qu Zhi said as he took out his mobile phone to see if he had flaunted his wealth in Moments, and deleted it quickly if he did, "This murderer's psychology is dark enough , If you kill people with such a shit, you won’t be mentally ill, right? You said that if we catch ‘him’ in the future, ‘he’ will open a psychiatric examination, wouldn’t he be exonerated?”

"'He' is not mentally ill." Hua Chong stroked his chin and said, "I think 'he' is very sober."

"That's true." Qu Zhi said: "With such a strong sense of anti-reconnaissance, it is impossible to have a mental illness. By the way, how is the investigation with Brother Xiaoliu?"

"Still investigating." Hua Chong stood up, "I'll go out for a while."

"Where are you going?" Qu Zhi covered his sore waist and grinned, "I'll be with you."

"You rest, don't break your old waist." Hua Chong slightly raised his hand, "I'll go to Xu Yujiao's house to see."

After the case happened, no one lived in Xu Yujiao's home. Even Xu Qiangsheng and his wife were only accompanied by the police to pack some of Xu Yujiao's things.

Hua Chong put on the shoe covers and went directly to the second floor.

Xu Yujiao's computer had already been taken away. The Technical Detective had checked it thoroughly but found nothing. Liu Zhiqin is currently keeping the computer.

The study was still the same as last time. Hua Chong stood in front of the bookcase for a long time, opened the door, and took out the history books inside one by one.

He didn't know if he could find anything in this study.But now the case has reached a stalemate, and everything that can be investigated has been investigated, and the only thing left is the deceased's network relationship.But even so, it is impossible to put the treasure on Liu Zhiqin alone.If Liu Zhiqin couldn't identify the suspect, then these two cases would really become unsolved cases.

This kind of thing must not happen.

Liu Zhiqin is right, crime is addictive.

Judging from the ceremonial acts of venting anger performed by the murderer on Xu Yujiao, "he" enjoyed the process of torture and killing very much, and obtained unparalleled pleasure from it.Tang Su died on January 1th, and Xu Yujiao died on March 4th, with an interval of two months and ten days.According to the law of addiction, the time interval between the murderer's next attack will not exceed two months and ten days, and 'he' may be eagerly looking for the next prey.

Who is it!

Hua Chong sat on the ground, flipped through one book, and then another.Xu Yujiao has a good reading habit, so she should cherish books very much and never bend the corners. The bookmarks she uses are exquisite and beautiful, and each one is different.

"Each book deserves a bookmark?" Hua Chong sighed and continued to move other books in the bookcase.

Suddenly, a book placed on top fell down and fell upside down on the ground.Hua Chong bent down to pick it up, the pages rustled, and a piece of paper wider than the bookmark slipped to the ground.

It's a postcard.

Hua Chong squatted down, frowning slightly.

On the front of the postcard was Suzhou Shantang Street, and on the back were written three lines:

To Jiunian

This is my first time to Shantang Street, I really like it here.Send us the pictures of Jiu Xiaonian, best wishes!

Stars determined to travel all over China

Hua Chong held the corner of the postcard, and his heart beat suddenly.

The sender signed the letter "Xing Xing" and called Xu Yujiao "Jiu Nian", which could only be a friend Xu Yujiao met on the Internet.

Before Zhang Mao and others had checked very clearly that Xu Yujiao never chatted with colleagues, relatives and friends about online affairs, and even her parents didn't know that her online name was "Chang'an Jiunian".

This "star" knew Xu Yujiao's address, and sent Xu Yujiao a travel commemorative postcard on Shantang Street. It should be a netizen who has mutual fans with Xu Yujiao.

On Tang Su's desk, there is also a picture postcard framed in a photo frame.At that time, Hua Chong wanted to open the photo frame to see what was written on the back, but was interrupted by Liu Zhiqin's words, and then forgot about it.

The front of that postcard is not Suzhou Shantang Street, but a nondescript mountain forest. Hua Chong couldn't tell where it was for a while.

Now Xu Yujiao's home also has a picture postcard. Is there any connection between the two?

Hua Chong put the postcard from Shantang Street on the table. On the address column of the postcard, only Xu Yujiao’s address was written. The place where the letter was sent was a time post office on Shantang Street. Judging from the postmark, the letter was sent 4 years ago. September 9.

The surveillance from 4 years ago has long been deleted.

Hua Chong picked up the phone and dialed Liu Zhiqin.

"Flower team." Liu Zhiqin's voice was a little distorted, and he seemed to be a little less smiling than when talking face to face.

"Check if there is a 'star' in the ID among Xu Yujiao's mutual friends." Hua Chong thought for a while, and then said: "If you change the ID, can you still find out?"

"Yes. Put it on me."

After hanging up the phone, Hua Chong continued to search on the bookshelf.

I didn't read carefully the last time I came here, but this time I realized that many books contain postcards of scenery.

Xu Yujiao seems to be using them as bookmarks.

Hua Chong neatly placed the postcards he found on the table. There were 14 in total. They came to Los Angeles from all over the world and sent them to a girl named "Jiu Nian".

Then the one in Tang Su's photo frame might have been sent by a netizen.

Just thinking about it, the phone rang.

"I found out, 'Xing Xingjiang who never sheds tears', female." Liu Zhiqin said: "She has interacted with Xu Yujiao a lot, and she also posted a gift from Xu Yujiao on Weibo. She once collected information on Weibo. The address of the netizen, who said she wanted to send a postcard, Xu Yujiao sent her a private message to tell her her home address."

Hua Chong pursed the corner of his lower lip.

"However." Liu Zhiqin paused, "This girl passed away 2 years ago."

"Dead?" The instinct of the police made Hua Chong immediately vigilant, "What is the cause of death?"

"Sudden cerebral infarction. Her real name is Zhou Chenxing, from Yaoshi. She was only 25 years old when she died of illness. Her family posted an obituary on her Weibo, and there was a message from Xu Yujiao in the comments." Liu Zhiqin asked: "Flowers Team, did you ask me to check her to find out that she has something to do with the case?"

Hua Chong opened the chair and sat down, his eyes fell on the postcards on the table, "Before I called you, I found the postcard sent by Zhou Chenxing from Suzhou Shantang Street in Xu Yujiao's bookcase. Since she knows Xu Yujiao's Home address, then I guess, as a netizen, they should have a good relationship. And her signature is "Xing Xingjiang who is determined to travel all over China". She. But then I found another 13 landscape postcards, of which 14 are from domestic scenic spots and 9 are from abroad. It seems that they were all sent by Xu Yujiao’s netizens. Put them together with these postcards, Shantang Street This one is no longer specific.”

Liu Zhiqin was silent for a few seconds, "Flower Team, I seem to understand why you care about 'resolve to travel all over China'."

"Ok?"

"Fulfilling one's wish can bring people endless joy and a sense of accomplishment, but what about the fulfillment of the wish?" Liu Zhiqin said: "While the wish of 'traveling all over China' is fulfilled, I see the friends who sent postcards in the past travel around freely. What's the mood in the whole world?"

"Normal people's mood is of course envy, and then continue to live their own lives." Hua Chong was a little surprised - when dealing with a case, he is used to collecting many clues that have no clue, but he doesn't think about them immediately What is the deep relationship between the clue and the case.Zhou Chenxing's "traveling all over China" made him care, which can be said to be out of professional instinct and sensitivity.But at least for now, he hasn't had time to think about the reason.

Liu Zhiqin helped him think about it.

"And the suspect we are looking for is destined not to be a normal person."

Hua Chong leaned back in the chair, "I seem to have caught a clue."

A very light laugh came from the receiver.

Hua Chong felt something like a feather was scratching his eardrum.

He straightened his back and cleared his throat, "I'll send you photos of the backs of these 14 postcards, first you can see if you can find the Weibo corresponding to the sender. I have seen the postmark time, and they are all 4 years ago It was sent, which means that Xu Yujiao and her circle used to send postcards to exchange feelings four years ago."

"Okay." Liu Zhiqin asked, "Are you staying at Xu Yujiao's house?"

"I'll go to Tang Su's house later. Remember, when we went last time, there was a framed photo on her desk, and there was also a picture postcard inside, which is the same type as Xu Yujiao's house." Hua Chong said : "But Xu Yujiao used the postcard as a bookmark and put it in the pages of the book, which didn't seem to be very cherished. But Tang Su put that in the photo frame and can see it every day, which means that it is a postcard that is very important to her. "

"Flower Team, you observe carefully." Liu Zhiqin said.

While chatting about the case, Hua Chong was suddenly praised. Before he could answer, Liu Zhiqin said with a smile: "Learn from the Hua team."

Hua Chong almost saw Liu Zhiqin salute with a slight smile.

After putting down the phone, he was in a daze for a few seconds, and suddenly felt an elusive feeling in his heart.

I haven't been with Liu Zhiqin for a long time, and I haven't seen him do similar actions, but it's effortless to imagine it just now, as if Liu Zhiqin saluted him with a smile a long time ago.

Deja vu, but difficult to trace back.

He furrowed his eyebrows and closed his eyes subconsciously.
