Knowing that the other party would arrive at five o'clock in a vehicle transporting drugs, Zhang Wenhao has been guarding the top of the water tower motionless, for more than two hours, these people will rarely use the walkie-talkie to communicate with each other, basically in absolute silence, until 4:40, a voice came from the walkie-talkie, said: "Cheer up, the car will arrive soon!" ”

The five guards outside immediately heard the sound and moved, the guard on the roof simply stood up and looked around, from the roof of the factory, you can see the road outside the food factory, Zhang Wenhao was condescending, and soon saw the car lights in the distance, looking at the distance between the two lights, it should be a truck.

In about a few minutes, the truck drove to the door of the food factory, the door of the food factory was opened, after the truck poured in, the gate was immediately closed, and then, the door of the factory opened, and six young people wearing work clothes and masks came out at once, and the containerized truck opened the door from the tail, and the workers moved the rectangular boxes from the car and moved them directly into the factory, but after everyone moved things in, they had to stay in it for two or three minutes, two or three minutes later, These people took out all the boxes they had moved in before, sent them to the car, and then brought down another batch, and so on.

The whole unloading and loading time lasted for nearly an hour, and the time reached about half past six, and the intercom came again from the previous commanding voice, saying: "Everyone come in first to rest, Xiaosi, you go out to guard the door, and wait until after half past eight." The truck then leaves, and when the time comes, the food on the truck is delivered directly to the dealer. ”

The intercom came the voice of everyone confirming the order. Subsequently, all five guards entered the inside of the factory. In the entire courtyard, only the truck and the driver remained, and there was a guard in a security uniform.

This drug processing factory, which was disguised as a food factory, did a lot of drama, and according to their sporadic conversations, Zhang Wenhao could basically guess their operation mode and the vehicle that transported the food. The food that was supposed to be ordered from elsewhere was brought here and transported here with the drugs, which were then detained by the people in the factory, and then the trucks delivered the food to the dealers. To make the illusion of normal operation, for such a remote and inconspicuous small food factory, no one will take the initiative to doubt it.

At half past eight in the morning, the truck drove out from the food factory, the door of the food factory was closed, but the small door was opened, and the guy in the security uniform came directly to stand guard outside the door with a rubber stick, and from the outside, the food factory opened the door. And there are security guards standing guard, presumably they have already started working, even if ordinary people pass by in front of the door, they will never be suspicious, but no one knows, at this time, the people inside, but all of them are resting in the factory, waiting until the evening, and then continue to engage in their illegal activities.

Zhang Wenhao was also at this time. I put away my bird-watching goggles and tripod, entered the water tower from the top of the water tower, left the bird-watching goggles and tripod in the water tower, and left here quietly.

After driving back to Zhonghai City, Zhang Wenhao found a high-end hotel to live in, and after taking a simple shower in the room, he came to the desk in the suite and drew a simple flat map on it with a pen and paper.

According to his memory, Zhang Wenhao first planned the most suitable approach route, after planning the approach route, Zhang Wenhao looked at the floor plan, the figure on the roof of the factory, and couldn't help but worry.

In any case, killing the guards on the roof is his first step, and it is the most difficult to kill him, and he must not let anyone notice, only in this way can he make a good advance measure, first ambush on the roof, waiting for the arrival of Ruan Da and Ruan Er.

However, how long will it take for Ruan Da Ruan Er to arrive?

…,

Although the two of them have formed a law in their actions, they will never strictly abide by a certain rule in terms of time, so that after Zhang Wenhao kills the person on the roof, if he waits on the roof for one more minute, he will be more exposed.

Zhang Wenhao thought of Xiao Er, who had great powers, and asked: "Xiao Er, if you invade the monitoring system of the entire industrial zone, can you accurately grasp the time when Ruan Da and Ruan Er arrived at the food factory?" ”

Xiao Er opened his mouth and said: "Boss, over there in the industrial zone, the surveillance video is not complete, the monitoring equipment at some intersections is in disrepair, and it is also a forgotten lot in the eyes of the traffic police, Ruan Da Ruan Er started from the urban area, after driving into the expressway, the distance of the monitoring equipment is very large, some sections of the road have no intersection for more than three kilometers in a row, that is to say, there is no monitoring equipment for three consecutive kilometers except for the electronic speed measurement device, in this section of the road, I can only roughly locate them through mobile phone signals, but, Only through the mobile phone signal positioning, the vehicle is moving, the accuracy is not high. ”

Zhang Wenhao smacked his lips and said: "If the accuracy is not high, the error will be widened, and if I start one minute earlier and one minute late, it may bring trouble." ”

Xiao Er nodded and said: "I can only capture their images through surveillance when Ruan Da Ruan Er enters the first intersection of the industrial zone, but from there, it is only about a kilometer away from the food factory, and there is almost no car on the road at night, so they may arrive within a minute." ”

"One minute" Zhang Wenhao pondered for a long time and said: "If I say so, I must approach the wall at the back of the factory before Ruan Da Ruan Er arrives at the first intersection of the industrial zone, and I can't be discovered by the guards on the roof, and then, when Ruan Da Ruan Er appears at the first intersection, I have one minute to quietly kill the guards on the roof." ”

"Yes." Xiao Er said: "This is the most stable, as long as the boss can solve that person within a minute, Ruan Da and Ruan Er will arrive immediately, after the two of them arrive, at most another minute, the door of the factory will be opened, but, when the factory gate is opened, Ruan Da Ruan Er should have arrived at the door, and the moment they enter the door, it is only a few seconds, and you have to kill the remaining four guards as quickly as possible at this moment of a few seconds, and then kill Ruan Da Ruan Er, at the same time, You also have to prevent the other party from closing the door, otherwise, you will not be able to enter. ”

Zhang Wenhao thought for a moment and said: "If that's the case, when Ruan Da Ruan Er is about to enter the door, I can first use flashbangs to temporarily blind the people outside the door and the people near the door, and they are suddenly attacked and temporarily blind, within a few seconds, it should not be possible to close the door very accurately, at this time, with M4A1, it should be possible to kill all six people outside, including Ruan Da Ruan Er, and then go down directly from the roof, before the gate has time to close, kill the people in the factory and the closest to the gate." ”

Xiao Er nodded and said, "Then you can throw another flashbang into it, and then rush inside and finish everyone else." ”

Zhang Wenhao sighed and said, "If there is not much defense force inside, it should be possible to complete the clearance in a very short time." ”

"What about after the clearance?" Xiao Er asked curiously, "Boss, what are you going to do?" ”

"First destroy all the clues related to me, including footprints and bullet casings, and then drag all the corpses into the factory and burn the entire factory."

Xiao Er said: "Boss, don't forget, start from where you parked, after you get out of the car, walking close to the factory and climbing the factory will leave traces, you need time to get all these traces, but if you set fire to the factory, the fire in the factory will soon be exposed, although there are few people, but such a big thing as a fire in the middle of the night can also be seen from a distance of several kilometers." ”

…,

Zhang Wenhao nodded and said, "Then I'll think of a way to delay or remotely control the ignition, people withdraw first, and after all traces are done, then ignite." ”

"I have a way." Xiao Er smiled: "You go and buy a mobile phone, and then buy the most ordinary resistance wire, and some simple tools." ”

Zhang Wenhao asked curiously, "Little Er, what are you going to do?" ”

Xiao Er smiled: "Teach you to make the simplest remote control ignition device." ”

Zhang Wenhao immediately went out and bought a mobile phone with a battery capacity of 1,500 mAh, and then according to Xiao Er's instructions, he bought the most common resistance wire for electric stoves, and bought equipment to disassemble the mobile phone, and then returned to the hotel.

As soon as he returned to the hotel room, Xiao Er instructed Zhang Wenhao to cut the resistance wire first, and the cut resistance wire was only about one centimeter long, and then Zhang Wenhao used the small file he bought to grind the resistance wire very finely.

Then, Zhang Wenhao used a screwdriver to remove the front of the mobile phone, removed the miniature vibration motor of the mobile phone, and then pulled out the power supply line and connected it to a resistance wire that was only one centimeter long and had been finely grounded.

After connecting, Xiao Er smiled and said: "Boss, you change the vibration mode of the mobile phone to a long vibration, and then your hand must not touch the resistance wire, just put it aside, pull a paper towel from the side and cover it on the resistance wire." ”

Zhang Wenhao nodded, and directly put the modified mobile phone on the table, and then, the mobile phone that was originally locked suddenly lit up! It even prompted that there was a call incoming.

When a phone call comes in, the mobile phone that is set to vibrate for a long time will continue to deliver power to the vibration motor to rotate the motor and cause vibration, but the vibration motor has been removed by Zhang Wenhao and replaced with a finely ground resistance wire.

The resistance wire is the heating equipment used in the electric furnace, once the power is on, the resistance wire will be heated, but this resistance wire is used in the electric furnace, the length of the original circle is more than half a meter, and the resistance wire is thicker, if you want to drive such a resistance wire, you must at least have a voltage of 220V, and the power is also more than 1500 watts, but now the resistance wire connected to the mobile phone is only about one centimeter long, and it is ground very fine, so the power of the mobile phone is enough to make it start heating.

Soon, white smoke began to come out of the paper towel covering the resistance wire, and then the part of the paper towel closest to the resistance wire began to turn yellow and black, and suddenly, the flames burst out.

Zhang Wenhao hurriedly took away the paper towel, threw it into the paper basket and extinguished the fire with the water in the cup, and then looked at the small section of the resistance wire, which was burned red!
