Ran Xiaoke carefully observed every detail of the video of Zhang Meng being tied.

A very small room, with a window in the background, the outside light is obscured by a curtain cloth, a layer of ordinary screen curtain cloth embroidered with a peony pattern, but it can be seen that it is already dark outside, and no light is letting in. There are walls on the left and right, and there is a wall clock on the left wall, the hour hand points to 7, and the minute points to 35, which means that the time in the video is 7:35!

Ran Xiaoke immediately raised the Longines mechanical watch in his left hand, 7:35!

It is almost certain that the video is a live video, not a historical footage.

There is nothing particularly valuable about the other environment.

Ran Xiaoke turned her eyes to Zhang Meng, she was tied her hands behind her back on the iron chair, her mouth was gagged, and she looked very tired after struggling for a while, but she was slightly flustered, her eyes were desperate and helpless. Dressed in some sportswear, cleanly dressed and free of blood or other obvious signs of beatings.

Ran Xiaoke didn't expect that he would never see each other again after graduation, and his girlfriend who occasionally remembered would meet again in such a scene.

His intuition told him that Zhang Meng was innocent and came for him Ran Xiaoke.

The environment in the house was too simple and did not give Ran Xiaoke more information.

Just when Zhao Yixin was in a hurry and Ran Xiaoke was thinking. The video screen is rotated 180 degrees, as if the camera has been rotated half a circle.

The man in black appeared in front of the camera, still wearing a baseball cap, pressed so low that it almost covered his face, and only his mouth leaked.

At this time, the computer speaker made a sound.

"Hello Detective Ran! Don't ask me who I am, it doesn't matter, I'm just a nameless character. The important thing is that I need you to help me do something that should have been done by me, maybe, I don't have time, so I need to trouble you", the sound produced by the speaker is obviously processed by voice change.

"Your girlfriend is safe for the time being, as long as you and your father appear on the rooftop of the Sky Tower at 8:30 tomorrow morning, you accompany him, I will call you on time at 8:30, if your father is not there, or your phone can't get through, I'm sorry, you may say goodbye to Zhang Meng! By the way, I have your phone number."

The man in black did not say why Ran Xiaoke brought his father to the Skyrim Tower, nor did he explain why he wanted to talk to his father.

Then the man in black turned the camera 180 degrees and turned it at Zhang Meng. The man in black tilted the camera up a little angle, and a sharp sword hanging about 1 meter on Zhang Meng's head appeared in the lens, and the man in black took an electronic display screen and gave a close-up in front of the camera, there was an electronic display screen on the object, and the man in black pressed a button, and the time on the electronic display screen began to change.

14:00:00——13:59:59——13:59:58......

The man in black connected the line of the electronic display screen to a small motor next to it, and the shaft of the small motor is connected to a small vertical iron bar, as long as the small motor rotates, the vertical small iron bar will turn horizontally, and touch a row of dominoes, and obviously, the mechanism connected behind the dominoes in the lens is bound to trigger the flint roll at the end, and collide with another flint, light the candle next to it, and when the candle burns halfway, it will burn the rope next to it, and this rope, Just pulled the sword on Zhang Meng's head and hung it under the ceiling......

Very well designed!

There is no man in black in the camera.

In other words, Ran Xiaoke must follow what the man in black said, and take his father to the rooftop of the Skyline Tower at 8:30 tomorrow morning, and the man in black must talk to his father, otherwise, Zhang Meng will be torn up.

Zhao Yixin didn't know what to say anymore, he didn't expect that soon after he joined the work, he would encounter scenes that only appeared in movies, or that he had never seen such scenes in movies, and beads of sweat had already appeared on his forehead.

Ran Xiaoke's brain was running at high speed, and at the moment he didn't understand why the man in black wanted to see his father, why he was talking to his father, why he was on the rooftop of the Skyline Tower, the center of the entire city, the landmark building, the highest place, and to some extent represented the image of the mountain city.

He was very hesitant and entangled, should he obey the orders of others, or find a way to rescue Zhang Meng?

Time passes minute by minute, 13:59:30-13:59:29......

There was no choice, he decided to walk on two legs, trying to rescue Zhang Meng, and at the same time contacting his father, who was far away in the county seat, to rush to Shancheng immediately.

"Yixin, immediately contact Miss Xiao Wang to inquire about the IP address of the video surveillance peer, and see if you can verify the IP registration address; In addition, I immediately reported the situation to the leadership of the agency, requested technical support, and conducted a technical analysis of the sound just now, and analyzed the ambient sound to see if there was any point that could be broken through."

Ran Xiaoke passed the recording of the man in black who had just secretly used his mobile phone to use the special software for crime investigation to Zhao Yixin, he was still quite calm and clear-minded, Zhao Yixin admired the master even more, and the aura of Mount Tai collapsed in front of him and remained unchanged was very powerful.

"Understood", Zhao Yixin immediately acted according to the master's instructions.

Ran Xiaoke walked out of the living room to the balcony, looking at the lights outside, his feelings were very complicated, why his father would be involved, he was very puzzled, picked up the phone, flipped to the phone number of "Dad" in the address book, and was very hesitant to call him. If you tell the truth, how to describe the whole process. If so, what kind of justification should be made?

Fragments of his memories of him and his father slowly appeared in his mind.

He remembers that when he was a child, his father was busy with business to support the family, and many times he was out and about, and sometimes he was not able to come back during the New Year's holidays, and he spent more time with his mother. A lot of memories are vague, to a certain extent, his father's love is absent, Ran Xiaoke didn't know what business his father was doing outside, until Ran Xiaoke graduated from college, his father basically returned to the county, lived in the county for a long time, opened a store and did a small business with his mother.

In Ran Xiaoke's memory, his father was an ordinary person who couldn't be more ordinary, had no temper, and had no ability, and he didn't have the impression that many people had that his father was very tall.

He dialed the phone anyway, although he still didn't know the purpose of the black man's request, but in order to save Zhang Meng, he had to prepare for the worst.

The phone is connected.

"Dad, are you at home? Why? Ran Xiaoke's tone is normal, a homely way of chatting.

"At home, I'm watching TV with your mother," Ran's father replied.

"Our Public Security Bureau will organize a blind date tomorrow, and we require that at least one parent must accompany us, can you come?" , Ran Xiaokedao.

"Don't say it early, when is tomorrow? Your mother has caught a cold in the past two days and is not feeling well, if you must come, then I will come", Ran's father said.

Ran Xiaoke was happy in his heart, "It will start at half past eight tomorrow morning."

"Tomorrow morning at half past eight? Why didn't you say it earlier? Ran's father complained.

"Oh, don't you have several cases on your hands, and I've been running back and forth, I almost forgot about it, but the Political Department of the Public Security Bureau just called me to remind me, and I just remembered," Ran Xiaoke explained.

"Well, it's so late, I'll just drive from the county early tomorrow morning," Ran's father said.

"Okay, then you get up early, set an alarm clock at half past six, don't be late, and dress more formally tomorrow", Ran Xiaoke said.

"Okay, then I'll come to the city early tomorrow morning, see you somewhere," Ran's father asked.

"See you at 8:20 at the entrance of the Skyline Tower", Ran Xiaoke said.

"Okay, then first, I have to take out the suit and iron it," Ran's father said.

"Okay, then I'll see you tomorrow morning," Ran Xiaoke said.

Hanging up the phone, Ran Xiaoke let out a long breath, and his palms were sweating when he had basically never lied.

"Yixin, go back to the Criminal Investigation Department first", Ran Xiaoke said to Zhao Yixin.

"Oh," Zhao replied.

Back in the office, Ran Xiaoke came to the information brigade to see if the monitoring IP address was found, but the news he got was disappointing.

"Ran Tan, we checked the IP address of the monitoring, the IP of the other end is virtual, logged in from the virtual server in Southeast Asia, there is no use to land the actual address, the other party should be a network master, sorry, we can't do anything for the time being", Cai Glasses of the Information Brigade said to Ran Xiaoke.

"Thank you for your hard work", Ran Xiaoke didn't get angry with Cai Glasses, because he knew that the knowledge of the Internet was too big, and Cai Glasses did their best.

"Yixin, contact the public security bureau where Zhang Meng lives to see if there is a report that Zhang Meng was kidnapped, and if the local public security bureau is already investigating, see if there are valuable clues", Ran Xiaoke instructed Zhao Yixin.

"Okay, I'll contact you right away", Zhao Yixin said, and went to the office to inquire about the contact information of the Public Security Bureau where Zhang Meng was located.

Back in the office, Ran Xiaoke lay on the sofa and breathed a sigh of relief, too many things have happened in the past few days, and the amount of information is too much.

Lao Du seems to have died in a car accident, Lao Du's tattoo is exactly the same as the tattoo of the three truck drivers who were killed before, a man in black appeared at the scene, Lao Du's daughter-in-law committed suicide by gas poisoning at home, as if the gourd baby was suspected of cheating and murder, in fact, he had no time to commit the crime at all, the gray Great Wall Haval borrowed by the gourd baby appeared at the scene of the Lao Du accident, and was found at the abandoned construction site after being stolen, and received a mysterious note in the dance hall, which led the investigation direction to the original petrochemical plant, and found the story of He Ji Noodle Restaurant in the original petrochemical plant, The man in black is very likely to be the son of He Runfu, the owner of He Ji Noodle Restaurant, and he didn't find any clues about his son at He Runfu's house, but the computer showed a video of Zhang Meng being kidnapped, and he wanted to blackmail Ran Xiaoke to take his father to the rooftop of the Skyline Tower, as well as Zhang Meng, he never thought that his girlfriend who he hadn't seen for many years would appear in such a way, which was indeed a big surprise to him, and he didn't dare to act like this in the TV series......

He also remembered the picture of Zhang Meng being tied, the curtains, the clock on the wall, everything was not too special, and there was no more information, but he remembered that there was a faint sound of a train passing by when the man in black spoke, and the sound of the collision between the railway and the rails was low but crisp, there is indeed a railway in Shandu, but there are too many communities in the whole city through which the railway passes, and it is not clear which place it is, and even a general range cannot be clarified.

Thinking about it, Ran Xiaoke fell asleep on the sofa......

"Master, master", Zhao Yixin woke up Ran Xiaoke, "I got in touch, the local public security bureau said that it received a report from Zhang Meng's parents, saying that Zhang Meng lost contact when he went out to work in the afternoon, there were no witnesses, the mobile phone was turned off, and the local public security bureau has not yet grasped the exact facts that can reflect that Zhang Meng was kidnapped, so it is currently only being dealt with as missing, and the case has not been filed, and there are no more valuable clues."

"Got it, did you hear the sound of the train passing by in Zhang Meng's surveillance video?" , Ran Xiaoke asked.

"It seems that there is, a very low and slow sound of the train passing, there is", Zhao Yixin said in surprise, "But there are too many places where the train passes, and the scope cannot be demarcated", Zhao Yixin was a little disappointed again.

"Yes, we need at least one more piece of information to be able to delineate the approximate range," Ran Xiaoke said to himself.

At present, it seems that there is no better condition to rescue Zhang Meng, she should be safe for the time being, wait tomorrow to see what direction things are going Ran Xiaoke asked Zhao Yixin to rest first, and he fell asleep in the office in a daze......
