"Okay, let's go and see Lin Xiaoxiao's whereabouts in the past two days. Why don't you go to investigate the murderer first?" Meng Xingchen asked.

"I still have to send people to keep an eye on the six people from yesterday 24 hours a day. At the same time, send someone to check Charin's small social connections, if the murderer is not among the six people! Moreover, I think that if we find the lighter first, the murderer will naturally come to us. Shui Bingyu said.

Meng Xingchen then arranged for people to keep an eye on the six people and investigate Lin Xiaoxiao's social relationship.

After arranging these tasks, Shui Bingyu and Meng Xingchen came to the information center of the police station and activated the system surveillance video.

Shui Bingyu asked the technicians to call up the surveillance video of Lin Xiaoxiao's whereabouts for nearly a week.

"This Lin Xiaoxiao's daily life is quite regular, home, supermarket, gym, three points and one line. Meng Xingchen said while watching the surveillance video.

"Team Meng, have you noticed it, the day before the accident, Lin Xiaoxiao actually went to the gym three times! This is very unreasonable!" Shui Bingyu said with a frown.

She used to go to the gym once a day, and she came out in about two hours. Then go to the supermarket to buy something to eat and go back to the apartment. The day before she was killed, she went back and forth to the gym three times! Moreover, the next two times she came out in less than ten minutes! Could it be that she lost something and went back to the gym to find it?" Meng Xingchen asked.

"I think maybe she's hiding her lighter in the gym. Shui Bingyu said.

"She hid the lighter in the gym, so where can she hide it?" Meng Xingchen asked.

"In the locker of the gym!" Shui Bingyu said after a moment's thought.

"It's possible! Let's go to the gym now. Meng Xingchen said.

The fitness center that Lin Xiaoxiao often goes to has luxurious decoration and advanced equipment.

Although the little girl at the front desk of the fitness center took Shui Bingyu to find the locker rented by Lin Xiaoxiao, the locker was locked with a combination lock, and the fitness center did not have a spare unlocking tool. If you forget the secret, you need to send a verification code to the mobile phone of the person renting this locker before you can change the password to unlock it again.

Lin Xiaoxiao's mobile phone has been taken away by the murderer, if the murderer finds out that Lin Xiaoxiao put the lighter here, it will be troublesome!

"What could the password be?" Meng Xingchen asked with a frown.

"I think Lin Xiaoxiao is a smart girl, if she can guess that she will be killed by the murderer, she will definitely leave clues for the police!

When the two returned to the police station, the police officers who were responsible for investigating Lin Xiaoxiao's social relations and tracking the whereabouts of the six people also returned.

"Team Meng, water police officer, I am responsible for investigating the family background of the deceased, through contact with the responsible officer of the police station in the city where the deceased lived, I learned that the deceased was from Harbin, both parents are in Harbin, she went to Kyoto alone at the age of 16 to work, worked as a waiter in a restaurant, a cashier in a supermarket, and only started to do live broadcasts on the Internet in the last six months. She has no other relatives or friends in Kyoto, and usually spends time alone. However, according to the security guard of the apartment complex, the deceased's private life was not very scrupulous, and in the past six months, strange men have often been seen looking for her. A police officer reported.

"No wonder you have the money to get a membership card for that high-end fitness club!" Meng Xingchen couldn't help but sigh.

"Have you investigated Lin Xiaoxiao's social network?" Shui Bingyu asked again.

"Investigated. By contacting the operator of the social network, I was able to obtain the account and password of the deceased on the major social networks, but unfortunately, after logging in, the content was basically deleted. Even all her QQ friends, WeChat friends, and all chat history have been deleted. The little officer continued.

"Could it be that the murderer is one step ahead of us and has already deleted all this information?" Meng Xingchen asked.

"If the murderer really deleted all this information, it proves that the murderer is also not a simple person! Maybe we will soon find out that Lin Xiaoxiao hid the lighter in the locker of the fitness center! He has Lin Xiaoxiao's mobile phone in his hand, and it is very convenient to change the password and open the locker! We must quickly find the password of the locker. Shui Bingyu said with a solemn expression.

"Do you have any ideas?" Meng Xingchen asked.

"I haven't thought of it yet, so let's listen to the investigation of a few other people first. Shui Bingyu said.

"Team Meng, Marine Police Officer, I have contacted the forensic doctor, and the cause of death of the deceased was suffocation. At the same time, the composition of the anesthetic was found from the body of the deceased, which should have been injected from the back of the deceased's neck. A police officer reported.

"I checked yesterday that she had a tiny pinhole in the back of her neck, which turned out to be injected with anesthetic. Shui Bingyu nodded and said.

"Team Meng, Marine Officer, I was in charge of monitoring the six people in the apartment after last night, and none of them left their room last night. A police officer reported.

"Let's go, Team Meng, let's go to Lin Xiaoxiao's apartment again. Shui Bingyu said after listening to the situation report.

"Good. Meng Xingchen said categorically.

Coming to Lin Xiaoxiao's apartment again, the two began to search like a carpet again, not letting go of any items that could prompt the password.

The two of them were about to rummage through Lin Xiaoxiao's room, and they almost went to the house to uncover the tiles, but they still didn't find any valuable clues.

Just when both of them were about to give up, Shui Bingyu suddenly found that there were six original English books on the writing desk in the living room!

According to what I learned, Lin Xiaoxiao came out to work when he was 16 years old, and his education level was not high. How could she read these original books in English?

If she didn't look at it, she would buy it back and put it on her desk for what she would do?

Could it be that it is used as a façade? Let the people who come to her house see it, and think how high her education level is?

However, according to the security guard of the apartment, the people who came to find Lin Xiaoxiao were all men, and they should only look at Lin Xiaoxiao's appearance, who would care if she was a literate person?

Besides, she doesn't have to speak English during the live broadcast, and she doesn't need to learn English by herself?

The more Shui Bingyu thought about it, the more she felt that there was something strange about those six English books, so she walked over and began to look through those books.

She picked up the first book and found that there was a page with a corner folded!

She quickly picked up the next five books in turn, and found that one page in each book was folded!

She looked closely at the page numbers and was surprised to find that they were six digits!

27839！

Could this be the six-digit password for the locker!

Shui Bingyu was about to tell Meng Xingchen about this discovery excitedly, but heard Meng Xingchen say: "Come and see, I found a shredded photo from the trash can in the living room, and I put it together again." ”

Shui Bingyu hurriedly walked over and took a look, it turned out to be a photo of Lin Xiaoxiao and a man skiing in the snow resort!

Because both of them were wearing skiing equipment, ski hats, and face towels shining on their faces, they couldn't see the man's appearance clearly!

However, Shui Bingyu was surprised to find that the place where Lin Xiaoxiao and the man took pictures was actually in the ski resort where Shui Bingyu and the others went!

Could it be that Lin Xiaoxiao's death is related to Liu Mengbai!

"Let's go, Team Meng, let's go to the fitness center right away. Shui Bingyu said.

"What, have you found the clue to the password?" Meng Xingchen asked in surprise.

"I'll tell you on the way. Shui Bingyu said anxiously as she walked out of the house.

On the way to the fitness center, Shui Bingyu told Meng Xingchen about discovering the six English books.

Meng Xingchen was also very excited when he heard it, and felt that it should be the password prompt left by Lin Xiaoxiao.

The two came to the fitness center, Shui Bingyu came to Lin Xiaoxiao's locker again, she pressed the six numbers 27839, and the password lock was really opened!

In the locker, it was the lighter.

Shui Bingyu and Meng Xingchen took the lighter back to the police station.

Meng Xingchen turned on the lighter and saw what was inside, he couldn't help but exclaim: "This is a USB flash drive!"

"It seems that Lin Xiaoxiao must have mastered an ulterior secret before he was killed! This USB flash drive must have hidden the information that the murderer wanted!" Shui Bingyu also sighed.

Meng Xingchen immediately inserted the USB flash drive into the computer, and there was only one file in it, and he immediately clicked on the file.

20170126101055000

It's a full screen of number symbols again!

"Is it the transaction time and amount again?" Meng Xingchen asked in surprise.

"That's good!" Shui Bingyu nodded and said.

"Wouldn't this have something to do with Liu Mengbai's devil again?" Meng Xingchen asked in disbelief.

"You guessed right! When I saw Lin Xiaoxiao and that man, that ski photo, I thought of it! They also took photos in that ski resort! Now, seeing these number symbols, it proves even more that the murderer is related to Liu Mengbai! At least he had a transaction with Liu Mengbai to forget his worries!" Shui Bingyu said slowly.

"In the process of interacting with the murderer, Lin Xiaoxiao accidentally discovered this secret, and secretly copied the electronic file of the murderer's transaction details, wanting to extort the murderer fiercely! Unexpectedly, he was killed by the murderer!" Meng Xingchen continued.

"Lin Xiaoxiao must have thought that she would be killed by the murderer! That's why she hid the real USB flash drive in the locker of the fitness center, and there was nothing in the lighter at home! Moreover, she also left clues to the password for the police! Lin Xiaoxiao was really a smart girl! Unfortunately, her cleverness was not used in the right place, but on the contrary, she harmed herself!" Shui Bingyu said with some regret.

"It's a pity, I can't see that man's face clearly in that photo! He should be the real murderer!" Meng Xingchen said with some annoyance.

"It doesn't matter, I've probably guessed who the murderer is!" Shui Bingyu said confidently.

"Who is it? is it one of those six people?" Meng Xingchen asked with interest.

"Don't worry, if my guess is correct, he'll show up on his own in no time. When the time comes, you'll know. Shui Bingyu replied with a smile on her face.
