Chapter 5152: Unlocking expert

"After talking for a long time, I still have to rely on me." Sergey walked over and tested the wall with his hand.
Then he quickly found a hidden button. After opening it, a baffle floated on the wall, revealing the fingerprint lock behind it.
"It looks very advanced on the surface, but it's actually an old device from a few years ago." Sergey knelt down and opened his toolkit.
"Can you open it?" Lin Rui asked in a low voice.
"It may take some effort. The core of any electronic device is to use electronic signals to control machinery.
Electronic locks are ever-changing, but there are only a few mechanical structures, and there will not be much change.
It is like an unmanned car. Even if the vehicle can be driven unmanned, only the control system is changed. But the structure of the car itself has not changed, and there is still a chassis with four wheels. "Sergey looked closely, and reached out and took out something from his bag.
"Military thermite." Quickma nodded.
"This thing can quickly dissolve a hole, and then I can pull the thread out of it." Sergey nodded.
"You mean it's like stealing a car, just use two thread ends to light the fire?" Another mercenary asked in a low voice.
"If it is really that easy, everyone will become a master. This is a technical job. Without more than ten years of experience, it can't be done." Sergey whispered while picking the lock.
"Can't you just be quiet and concentrate on unlocking?" Kuaima shrugged.
"Speaking can disperse the pressure. This is a delicate task. It is not sloppy at all." Sergey said in a low voice, "In order to learn how to unlock, I worked as an apprentice in a German lock factory for two years, just to learn the lock body. structure."
Lin Rui winked at Kuima, "Be careful to cover him."
Quickly nodded.
Lin Rui pressed the communication headset and asked the black Mamba and others in the guard duty room.
"I'm Rick, what's the current situation? Is there any abnormal movement of the guard?" Lin Rui said in a low voice in the communication headset.
"Everything is normal at the moment. We can monitor the situation of the entire building here. Including your current location.
But there seems to be a problem. There is no camera surveillance behind the door you are opening.
In other words, when you open that door and enter, we may not be able to provide any assistance. "Black Mamba replied.
"Understood. Keep staring, and we will resolve it as soon as possible." Lin Rui cut off the communication.
Sergey is already using thermite to boil the sealed steel plate at high temperature. The intense light and scorching heat erupted from the thermite is slowly burning the solid steel plate.
After it boiled, Sergey kicked the panel suddenly, and a heavy steel plate rolled down, still emitting scorched blue smoke from the edge.
"It's done, brother." Sergey put his hand inside, carefully pulled out a circuit board, and observed it carefully.
"The three-circuit structure is quite complicated." Sergey frowned.
"What's wrong? Is it difficult?" Lin Rui asked.
"It's a little troublesome, but it will take a while, and it will be able to open sooner or later." Sergey nodded. "This three-layer circuit structure ensures that this station cannot be opened by violence. Because if the circuit board is simply used for short-circuiting, it may cause the electronic information circuit and the mechanical lock to be forcibly locked, thereby being completely locked.
I have to find a way to solve this problem. It takes about ten to twenty minutes. "
"As soon as possible." Lin Rui frowned.
He glanced down at his watch. It was nearly thirty-two minutes since they entered.
Although it was still early for the guard to change shifts, Lin Rui knew very well that he didn't have much time.
After all, although they have successfully sneaked in, the white gloves as the main target of the action have not been found.
If the delay continues, the situation may become very difficult.
But now even urging Sergey is useless. Unlocking is a meticulous job, and Sergey is a master in this.
The only thing they can do now is to continue to wait and pray that there will be no accidents.
As time passed, Sergey was still busy, and the others couldn't help much. Can only wait on the sidelines.
After waiting for about ten minutes, Sergey was still busy reconnecting the circuit board, which was a very complicated process.
He used a knife to carefully scrape the insulating layer of the circuit board, and then carefully completed the transfer.
Finally, I took out a pencil and drew it carefully on the circuit board.
Seeing quickly, he was a little anxious, he couldn't help but said, "Do I need a pencil to open the lock?"
"I don't need a pencil to unlock the lock, but I need to modify the circuit. First, I scraped off the insulating layer on the back of the circuit board with a knife, and then used a pencil to draw along the circuit I needed to modify.
Because the main component of the pencil lead is graphite, which is a conductive material, as long as you draw a few more layers, the circuit on the circuit board can be reconnected.
The current signal will follow the line I changed. Finally, the effect of changing the circuit board is achieved. "Sergey said as he kept doing it.
In fact, he is also quite nervous, as can be seen from the sweat on his forehead.
"Help me wipe my sweat." Sergey whispered, "If sweat drips on the circuit board and burns the circuit board, it will be over. You have to be very careful."
Quickly walked up and wiped his sweat.
"Thank you, it's almost a success." Sergey gritted his teeth and finally completed the modification of the circuit board.
"Di." There was a response on the fingerprint input device, and the light-emitting diode on the circuit board also lit up.
"It's done." Sergey finally breathed a sigh of relief.
"Alert!" Lin Rui immediately raised the weapon in his hand.
Kuaima stood beside him at the same time, and pointed the gun in front of him, the partition wall slowly rising.
When the partition wall was raised, they discovered that the entire partition wall was made of heavy steel plates.
No wonder Sergey had to use such a troublesome method instead of directly using blasting.
Behind the partition wall is a corridor leading to the last room.
Lin Rui waved his hand and made a warning to move forward.
The players all followed, and Sergey took up his weapon and followed them.
The three men formed a battle formation and burst into the door of the room.
"Go!" Lin Rui turned his head and made a gesture.
Kuaima immediately stepped forward and opened the door with a heavy kick. At the same time, Sergey threw a grenade that had opened the insurance through the door.
"Boom!" The fragmentation grenade made a huge explosion, and there was a scream from inside.
Lin Rui and Kuai Ma immediately rushed forward without losing the opportunity, and carried out a merciless massacre on the people inside.
The two assault rifles sprayed out long tongues of flame. The secret society militants who had just been attacked by grenades were shot and killed immediately before they recovered.
