In the conference room of the Criminal Investigation Detachment of Zhongjiang City Police Station, He Xiaohui, Su Le and the others were watching attentively as Dr. Qiao displayed his calculation process on the big screen through the computer.
"The height of the Eye of the Middle River is 128 meters. Based on the height of the subject and the location of the photographer, the angle between the camera and the window sill behind the subject can be calculated. According to the distance between the window sill and the Eye of the Middle River that we measured from the photo,
Looking at the angle between the eyes and referring to the ground undulations in Zhongjiang City, we can calculate that the height of the window sill is between 315 meters and 34 meters. From this, we can determine that the location where the photo was taken may be on the 10th or 11th floor.
." Dr. Qiao drew a circle somewhere on the screen with his stylus among a large pile of formulas.
"We investigated the area covered by Beicheng No. 116 Signal Tower. In this area, there are 11 high-rise buildings with a height of more than 10 stories. Based on the relative position of the shooting location shown in the photo and the Eye of Zhongjiang, we excluded
The other nine high-rise buildings are targeting the New Zhongjiang Hotel and the Central Building next to it."
Pictures of two high-rise buildings, the Sun Chung Kong Hotel and the Central Building, were displayed on the big screen. Dr. Qiao straightened his hair on his forehead and continued:

"The Xinzhongjiang Hotel is a 52-story building with a height of 150 meters. The 10th floor is the guest room of the Xinzhongjiang Hotel. The Central Building is the office building of the Central Industrial Company of this city. It is a 10-story building. What I can do at the moment
This is the information provided.”
"Okay, Xinzhongjiang Hotel or Central Building, Su Le, which one do you think we should go to first?" He Xiaohui asked.
"Well, let's go to the Xinzhongjiang Hotel first, and then send someone to check the background of Zhonghuan Industrial Company," Su Le said.
"Okay, let Yiran do the information checking, and let's set off with Pengfei."
The Xinzhongjiang Hotel building has guest rooms from the 8th floor to the 16th floor. When He Xiaohui and the others arrived at the hotel, they first checked the hotel's guest registration information and found no guests checking in with the names of Xie Xingye's family members. Then they focused on the 9th to 12th floors.
The list of guests staying at the Eye of the Chaozhong River in recent days did not find anything suspicious in the list. They also came to the guest room on the 10th floor.
They entered a standard double room. The window was facing the door. There were two layers of curtains on the window. There were two small sofas and a small coffee table under the window sill. In the middle of the room were two single beds.
bed.
Su Le stood at the window and looked out. The Eye of the Zhongjiang River in the distance was clearly visible. Comparing the angle, this location was similar to the shooting location in the photo. However, the difference was that there were curtains hanging on the windows of the hotel, while the one in the photo was
There are no curtains on the windows. Also, the style of the hotel window frames does not match the ones in the photos.
"Are all the windows in your hotel rooms the same?" Su Le said, pointing upstairs.
"Same, the guest rooms in our hotel are decorated together and have the same style." The waiter replied.
"Are there any hotel rooms without curtains?"

"How is that possible? If the curtains are not hung, the guests will not check in." The waiter replied in surprise.
"Okay then, let's go to another one."
When Su Le, He Xiaohui and Zhang Pengfei were in the elevator, He Xiaohui received investigation information about Zhonghuan Industrial Company from Ding Yiran on his mobile phone.
Information shows that Zhonghuan Industrial Company is a company engaged in coal mining, sales, and logistics transportation. Before the rectification of the coal mines in Zhongjiang City, Zhonghuan Industrial Company controlled and participated in dozens of private coal mining companies. After the rectification of the coal mines, Zhonghuan Company's main business shifted.
The company engaged in coal sales and logistics transportation. Through further investigation, it was discovered that the controlling shareholder of Zhonghuan Industrial Company was actually Hexi Tangqian Financial Investment Management Company.
"Haha, I really didn't expect that there is a company controlled by Tangqian Company in Zhongjiang City, thousands of miles away." Su Le said with a smile after reading the information sent by Ding Yiran.
"It seems that there is a high possibility that it is in Central." He Xiaohui said.
"Then how do we get in?" Zhang Pengfei asked.
"Since Zhonghuan Company is suspected of illegal and criminal acts in major cases, we can just go in and conduct a search," He Xiaohui said.
"What if they get wind of harming or transferring hostages?" Su Le said.
"Their purpose should be to put the hostages under house arrest or hold them hostages. We don't have to worry about them harming the hostages for the time being," He Xiaohui said.

"Well, that makes sense."
"I will immediately dispatch a small team of armed police to guard all the entrances and exits of the building to prevent them from transferring the hostages," He Xiaohui said.
Several police cars blocked the front door of the Central Building with their lights flashing. Armed police with live ammunition filed out of the police cars and began to block all entrances and exits of the Central Building in an orderly manner. There were armed police guarding the front door, back door and side door.
Anyone can enter or leave the building. The three elevators of the building are controlled by armed police on the first floor. Others go upstairs along the walking stairs, and people are left guarding the entrances and exits of each floor.
On the eighth floor of the Central Building, He Xiaohui met the panicked general manager of the Central Company. The general manager was sweating profusely and holding the phone in his hand, constantly inquiring for information. When he saw He Xiaohui and others coming in, he quickly put down the phone and came forward.
"Officer, officer, what's going on?"
"Your company building is suspected of harboring hostages. We need to conduct a thorough search of the building." He Xiaohui said seriously.
"Ah, harboring hostages? Search, search, you can search whatever you want." General Manager Zhang Er's monk was confused.
"Okay then, let's start from this floor first. Send someone to follow us and open the door."
"Okay, I'll make arrangements right away."
The general manager quickly took out his hand and called their security director.

"Minister Xie, where are you?"
"General Manager, I'm on the first floor."
"Come to my office quickly."
"General manager, but they don't let you use the elevator."
"You're not going to fucking come up!" The general manager was nervous and cursed.
He Xiaohui heard this and arranged through the intercom to allow Minister Xie to go up to the eighth floor via the walking staircase.
A few minutes later, Minister Xie, who was as fat as a ball and almost collapsed, came to the general manager's office, bent over and panting heavily. Upon seeing this, the general manager quickly introduced:
"This is Xie Yaqiu, the security director of our company. He is in charge of all the keys to the company. Ask him to take you to search."
"Okay, I, I'll take you, take you there." Xie Yaqiu was still struggling with his respiratory system.
"Okay then, let's take a look at this room first."

He Xiaohui and Su Le walked to the window unceremoniously and found that the location on the eighth floor was indeed a bit lower. The angle of the Eye of the River in the photo was not right, and the style of the office windows was also inconsistent with the photo, so they went straight up.
On the ninth floor.
The situation on the ninth floor was basically the same as that on the eighth floor. They searched all the rooms on the ninth floor and found that they were all independent offices and conference rooms. No clues related to the hostages were found.
After arriving on the tenth floor, Su Le first opened the window of a room facing the Eye of the Central River, compared it with the angle of the Eye of the Central River seen in the photo, and found that this position was very close to the angle in the photo. So they opened the window of the room on the tenth floor.
Searching every room found nothing, and the windows on the tenth floor were the same as those on the ninth and eighth floors, completely different from the windows in the photo.
"Why is this happening? Is there an error in calculation?" Su Le was communicating with He Xiaohui.
"Impossible, I trust Dr. Qiao's judgment."
He Xiaohui took the photo from Su Le and walked to the window. He held the photo in front of his eyes and compared it with the actual scenery. After looking at it for a while, He Xiaohui turned around and said:
"Su Le, I think this position is a bit low."
"Oh, is it on the top of the building?" Su Le pointed to it and said.
"Let's go and have a look."
He Xiaohui came to the corridor and said to Xie Yaqiu who was waiting:

"Where to go to the roof?"
"Ah! The roof of the building, from, from over there." Xie Yaqiu pointed to one side of the corridor, his expression obviously starting to look unnatural.
When they came to the stairs leading to the roof, an iron door blocked everyone's way, with a large copper lock hanging on the door.
"Please open this lock." He Xiaohui ordered.
"Oh, this door hasn't been opened for a long time. I'm going to look for the key." Xie Yaqiu replied.
Su Le stepped forward to observe the door lock and found that there was almost no dust on the door lock. It did not look like it had been touched for a long time, so he said:
"Okay, I'll go find the key with you."
When Su Le passed by He Xiaohui, he quietly said to her:
"Team He, call someone to extract the fingerprints on the lock."
Su Le followed Xie Yaqiu upstairs and downstairs several times, but could not find the key to the lock. However, the sweat on Xie Yaqiu's head was getting more and more, and there were already large sweat stains on the shirt on his chest. Back to the door
When he was in front of the door, he saw that technicians were already extracting fingerprints from the lock, and Xie Yaqiu's face became increasingly ugly.

After the technicians finished extracting the fingerprints, Su Le stood in front of Xie Yaqiu, asked Xie Yaqiu to stretch out his arms, and signaled two armed policemen to grab one of his hands and make him stand like a big character.
"Minister Xie, since you can't find the key, I'll help you find it."
Su Le reached into the inner pocket of Xie Yaqiu's left chest and took out a key with a lanyard attached to it. People at the scene were shocked when they saw Su Le's actions. They didn't know why Su Le could
Know exactly where the key is hidden.
"Haha, okay, great detective, now he is going to become a god!" He Xiaohui praised in public.
"What the hell, I'm just paying attention. In the process of looking for the key, Minister Xie unconsciously touched his pocket several times."
Su Le waved his hand and walked to the iron door and easily opened the door lock with the key. Xie Yaqiu could no longer stand at this time, so two armed policemen grabbed him and handcuffed him.
