Three days later, in the morning, at the gate of the International Conference Center.

In these three days, the wind and waves were calm, there were no clues, and nothing happened, the murderer seemed to have disappeared, this calm before the storm made Yang Zheng more and more worried, the only fortunate thing was that the special weapon arrived, and the thirty people who supported the SWAT team also arrived, and the leader of the team was the familiar captain, named Liu Wei.

Yang Zheng stood at the gate of the International Conference Center and looked out, in front of which were open squares and streets, the streets used to be high-rise buildings on both sides, the terrain was complex, and there were many doors in the International Conference Center, and the traffic was convenient, which meant that it was convenient for the murderer to infiltrate, and the defense was rarely increased.

Although Yang Zheng came with Gao Shou and Ah Mei, as well as Liang Fan and Liu Wei, Yang Zheng turned on the terrain around him for a moment, opened the map, drew circles at some intersections with a pen, and after drawing twenty, he motioned for everyone to gather around, and said in a deep voice: "Captain Liu Wei." ”

"Yes." Liu Wei hurriedly agreed, his eyes eager.

Since meeting Yang Zheng, Liu Wei has found that he can get credit for every action, and he likes this feeling very much, and is full of gratitude and admiration for Yang Zheng.

"With the conference center as the origin, there are many intersections within a radius of three kilometers, I have chosen twenty, I need you to appoint twenty people to go over, no one is squatting at an intersection, with a pistol on standby, you can help see if these twenty locations are suitable?" Yang Zheng said.

Liu Wei looked at the circles drawn on the map, covering almost all intersections, and also considered factors such as highways, expressways and one-way streets, and quickly said: "There is no problem." ”

"Don't be modest, if there are shortcomings, just say, we are all for the task." Yang Zheng said.

"It's really no problem, why don't I discuss it with you later?" Liu Wei explained.

"Okay, thirty of you came, select ten of the highest marksmanship, and the other twenty people will be assigned to these places to squat, listen to orders at any time, and report any abnormalities immediately." Yang Zheng admonished.

"Okay, I'll arrange it right away, but our people are scattered and ambushed three thousand meters away, what if something happens here? Wouldn't it be too far? Liu Wei kindly reminded.

"Liang Fan, what strategy do you usually adopt when you encounter this kind of thing?" Yang Zheng didn't answer immediately, but looked at Liang Fan next to him and asked in a deep voice.

"Generally, the inside is tight and the outside is loose to ensure the safety of the primary target, except for special ones." Liang Fan replied.

"This conventional strategy must be able to guess the murderer, so, I'm going to come the other way around, tight on the outside and loose on the inside, there are internal guards in the conference center, don't worry, we just need to close the outside, once the murderer is found, the grass startles the snake, scare the other party away, the murderer runs out three thousand meters away and does not see the pursuit, and generally relaxes, this is, the ambushed SWAT brothers carry out a sneak attack, and subdue the target in one fell swoop." Yang Zheng explained.

"Understood, I'll tell everyone, but we don't have a vehicle, and once the killer escapes, we can't pursue him." Liu Wei hurriedly agreed.

"It doesn't matter, if the murderer runs away, don't chase it, the pursuit is not good, it will hurt the innocent, let them run, and then sneak attack when they settle down, isn't there ten people reserved, these ten people are the reserves, however, I need the help of my brothers in the transportation department." Yang Zheng said and looked at Liang Fan.

"You say." Liang Fan hurriedly said.

Yang Zheng didn't answer immediately, but drew more than a dozen circles on the map, and then advised: "The brother of the special police is in the dark, and it can't be exposed unless necessary, these dozen points are about two kilometers away from the conference center in a straight line, and they are counted as the first defense line on the surface to help check for suspicious vehicles." ”

"No problem, I'll communicate with them." Liang Fan agreed.

Then, Yang Zheng drew more than 30 circles on the map, and continued: "These 30 locations are about 1,000 meters away from the conference center in a straight line, and they are also very important, and they are the necessary places for the flow of people. ”

"Yes, I'll arrange it right away." Liang Fan agreed.

"In addition, we need the armed police to help set up control and protect the surroundings of the conference center, the number of people cannot be less than three hundred, the Luo Bureau has already coordinated, you come up with a defense deployment plan as soon as possible, everyone must have clear standards in what position they stand in, it is recommended to rotate in two shifts and change the guard every hour." Yang Zheng admonished.

"Yes, I'll contact the armed police in a moment." Liang Fan hurriedly agreed.

Yang Zheng nodded, looked at Liu Wei and continued: "I also need the support of the SWAT team, it is best to send thirty people over, a group of two, men and women, and then police dogs, divided into two shifts, demarcate patrol areas, make a good rotation plan, etc., this is no problem, right?" ”

"I'll get in touch with my superiors right away." Liu Wei agreed.

"In addition, you will send another mobile team, four directions of the conference center, and deploy a mobile team in each direction, equipped with special vehicles, and put weapons on the vehicles for backup at any time, so as to calculate the third line of defense on the surface." Yang Zheng continued, glancing at the surrounding tall buildings.

"Understood, I'll report it as well." Liu Wei promised that the stakes were very high, and he could not make his own decisions.

"There are all high-rise buildings around, any place can be used as a sniper point, it is very dangerous, and it brings huge hidden dangers to our security. Yang Zheng admonished.

"Yes." The two hurriedly agreed.

Yang Zheng said in a deep voice: "Hurry up and deploy." ”

The two hurriedly walked to the side to make a phone call, Yang Zhengze looked ahead and pondered, Gao Shoushan came forward, stood side by side with Yang Zheng, and asked in a low voice: "Is the roof of the building ready to be handed over to me and Ah Mei?" ”

"Yes, thank you two for your hard work." Yang Zheng said in a deep voice.

"Little things." Gao Shou smiled.

Yang Zheng nodded, looking at the front with a calm face, his eyes gradually fell on a group of elderly tourists, more than a dozen people, who were talking and laughing in the area by the side of the road in the square, constantly taking pictures, or taking selfies, the tour guide was a little girl, explaining what to everyone.

"What's wrong? It's just a tour group, it's very common. Gao Shou asked in a low voice in disbelief.

"yes, it's very common, there are tours like this every day, right? So it's easy to be negligent, not to mention this kind of elderly group, it doesn't look threatening, it's more hidden, you pay attention to the man in the team who helps people take pictures, he looks about sixty on the outside, and his body is not very good, but he has been taking pictures in a half-squatting position for several minutes, and he constantly directs everyone to pose in various poses, tirelessly, and his body is so good? Don't you think it's weird? Yang Zheng said in a deep voice.
