A large number of armed police cordoned off the entire office building of Tangqian Company and excluded all people from Tangqian Company. Just as Geng Yuanliang led the task force to cooperate with the investigation team in conducting on-site investigations, Su Le came to the office building of Tangqian Company alone.
For safety reasons, the electricity in the office building has been completely cut off. Su Le went up to the top floor via the walking stairs on the other side of the explosion point. What he had always been worried about Tangqian Company was the monitoring system of the office building. The system exposed from the explosion point
Some people have seen that there are a large number of burned video cables in the ceiling of each floor, so Tangqian Company must have installed a hidden surveillance system.

Evidence may be found that they were involved in selling bank cards to money laundering agencies.
According to Cao Min's explanation, the control room is likely to be located next to the elevator room. Su Le found a metal door without glass next to the elevator room. Because this door was far away from the explosion point, it was not affected by the explosion and fire. Su Le
Le reached out and pressed the door handle and found that the door was locked.
Su Le turned around and looked around. He originally wanted to find a tool to break open the door, but then he thought that there was no need for it now. They had completely sealed the building and could open the door through legitimate channels.
Su Le turned around and went back downstairs, and at a glance he saw the beautiful office director standing in front of the crowd with a frightened look on his face. He spoke to the armed police on duty, and took the beautiful director Xie to the door and said.
"Director Xie, please open this door."
"Here, here, I, can I make a phone call?" Director Xie said with an embarrassed look on his face.
"Whatever." Su Le waved his hand and said.
Director Xie took out his mobile phone and walked aside and made a low-pitched call for a while, then told Su Le to go downstairs to get the key. In order to prevent her from making unnecessary movements, Su Le followed her to the office on the first floor and got the entire office
Spare key to the building.
"Okay, I can go up by myself. I'll take you out now." Su Le said to Director Xie.

"Ah, no, can I go up with you?" Director Xie left like this with obvious reluctance.
"Please go out. I will call you again if something happens." Su Le escorted Director Xie to the outside of the cordon again.
Opening the door of the monitoring room, Su Le was stunned. On one wall of the monitoring room, there was a wall full of monitors. Due to the power outage, the monitors were all black screens, like rows of neatly arranged guards.
It's really pretty.
Su Le took out the tools he carried with him, skillfully opened the computer case and removed the hard drive inside. Looking at the heavy hard drive in his hand, Su Le showed a knowing smile on his face.
After dawn, Liang Shi finally woke up. He rubbed his red and swollen eyes, stretched his aching body, and found himself lying in a strange place. He climbed up and saw the iron railings in front of him.
Liang Shi calmed down, patted his still sore head, stood up and walked to the iron railing, grabbed the cold iron railing and shook it vigorously a few times.
The policeman on duty came over and yelled at him:
"Be honest and sit down."
"Brother, where is this?" Liang Shi asked.
"Police station, don't you recognize it?"
"Why did you bring me in?" Liang Shi asked puzzledly.

"You'll know soon." The policeman on duty turned and walked away.
Liang Shi was quickly taken to the interrogation room.
"Name?" Liang Ronghua asked seriously.
"Liang Shi." Liang Shi looked at the serious-looking Liang Ronghua and the policeman sitting at attention next to him. He was quickly thinking about how he got here? Why did Liang Ronghua look so ugly?
"What did you do last night?" Liang Ronghua began to ask.
"Last night? I went drinking."
"Who did you drink with? Where did you drink?"
"Two elementary school classmates, and one who seems to be named Yao Huang, and this Yao Huang's nephew." Liang Shi frowned and thought carefully.
"Where to drink?"
"Well, it seems to be called Hutongkou Local Food Restaurant."

"What happened while you were drinking?"
"What happened? Oh, it seems like there was a fight with someone." Liang Shi finally remembered that he had been fighting with someone.
"Why do you fight with people?"
Liang Shi tried hard to recall the fight last night, but he could only remember that he had fought before. As for why he fought and the process of the fight, he couldn't remember. Liang Shi thought for a long time and could only shake his head helplessly and said:
"I can't remember."
"Did you know that you killed someone in the fight last night?" Liang Ronghua asked angrily.
"Beat someone to death? Is this impossible? I can't remember it at all." Liang Shi looked at Liang Ronghua with wide eyes and said.
"The witnesses and evidence chain at the scene are complete. It doesn't matter whether you remember it or not."
Liang Ronghua showed the photos taken at the crime scene to Liang Shi. Liang Shi's mouth opened wide and his eyes almost fell out of his sockets. He looked at the photos of the deceased lying in a pool of blood and himself lying in the corner sleeping soundly.
, unable to say a word. He finally understood why he appeared in the police station.
Liang Shi lowered his head in pain, rubbed his sore and swollen temples with both hands, and tried hard to recall the details of the drinking session last night. Suddenly he suddenly raised his head and said:

"We will. After you finish taking notes here, we will send you to the detention center. In the detention center, you can recall the details of the drinking and fighting last night."
After finishing the interrogation of Liang Shi, Liang Ronghua dialed Liang Yinghong's phone number.
"Miss Liang, I have some bad news for you. Liang Shi has been arrested."
"Ah, why?"
"He was drunk and beat someone to death last night."
"He beat someone to death? How is this possible? He was at a party with his elementary school classmates yesterday."
"When we arrived at the scene, he was lying next to the deceased and sleeping soundly. Witnesses confirmed that he chased the deceased into the alley."
"What did Liang Shi say himself?"
"He himself doesn't remember the fights and injuries. He must have been drunk."

"Drunk? That's even more impossible. You should know how much he drinks. Three pounds of liquor is just a mouthful to him. How much did they drink yesterday?"
"These matters are still under investigation, Miss Liang, please don't worry yet."
"Okay, anyway, I think it's impossible for Liang Shi to get drunk."
"Well, Miss Liang, now that Liang Shi is not with you, you have to be more careful. Otherwise, you should go to the south and stay for a while. Liang County is becoming more and more unsafe."
"So many things have happened recently, how could I just walk away?"
"Okay then, be safe."
"Oh, by the way, I heard that there was an explosion in the office building of Tangqian Company." Liang Yinghong asked.
"Yes, I looked at it at night. It seemed that a car was packed with explosives and parked behind the Tangqian company building. A corner of the office building was blown off. The damage should be considerable. Now the task force has taken over the case.
"
"Who would attack the Xie family?"
"Yes, I feel very strange too. I don't understand how such a thing could happen."

"Okay, we will communicate in time if there is any situation."
"Okay, Miss Liang, please pay attention to your safety."
After a whole day of intense investigation, the task force and investigation team had basically completed their investigation and evidence collection work by 12 o'clock on the night of the explosion. They gathered at the task force's office and held a meeting overnight to report the case.
Experts from the investigation team first introduced clues about explosives.
"From the smoke rising from the explosion site and the analysis of the chemical elements remaining at the site, we determined that this was still an explosion caused by ammonium nitrate. We also found residues of emulsion explosives and the outer packaging of the detonator at the explosion site."
"At the explosion site, we also found the same original electrical components as those used in the explosion of Liang Fei Co., Ltd. We also found a mobile phone sim card at the site. Fortunately, the card number of this sim card is complete."
"Based on the above information, we believe that this explosion and the Liang Fei Co., Ltd. explosion may be a series of cases planned by the same group of criminals."
Subsequently, members of the task force also introduced their findings at the explosion site.
"We also found some clues in the bombed van with only the front half remaining."
"Through the inspection of fingerprints in the cab, we found that the entire cab had been carefully cleaned, and we did not find any fingerprints on the steering wheel, door handles, etc. This shows that the criminals were wearing gloves after cleaning the fingerprints in the car.

"However, we found a pack of blackened facial tissues under the driver's seat. The facial tissues had been opened and used, and there were still 7 pieces left in it. On the outer packaging of the facial tissues, we found three fingerprints."
"In the sewing interface of the driver's seat, we also found a hair about 12 centimeters in length. We conducted DNA identification on the hair, but no matching object was found in our DNA information database."
"We also found another item in the broken cab, a bronze bracelet." The technician picked up the physical evidence placed in the plastic bag and showed it to everyone.
Su Le stood up suspiciously, walked behind the technician, took the bracelet and observed it carefully. What he didn't expect was that the bracelet was exactly the same as the one in his pocket. Su Le took a breath of cold air.
Angry, he did not boldly explain his findings to the task force and investigation team.
"We investigated the SIM card found by the investigation team and learned the phone number it corresponded to. We also found the communication records of this phone number. We found that another phone number had called this phone number when the explosion occurred.
number. We believe the criminals used this call to detonate the detonator."
"We checked the phone number and found that the name of the owner of the phone number is Liang Yinghong."
The appearance of this name did not surprise Su Le. When he saw the bracelet just now, an unknown premonition had already arisen in his mind.
