When Zhou Hua and Lin Cheng re-entered the residential building, Wang Dang walked up immediately, and before Lin Cheng could speak, he said apologetically, "Little brother, don't mind too much just now, I really didn't mean anything malicious when I said that, it's just that I have a bad mouth, and I haven't changed it. I apologize to you, I was wrong. "
As the saying goes, don't hit a smiling person with your hand. Seeing that Wang Dang said that, what else could Lin Cheng say, he could only smile, and said calmly: "It's okay, I can understand that you were not in a good state of mind at the time. "
Seeing that the two had already talked, Zhou Hua said: "Okay, time is running out, little brother, you should hurry up and help us open this damn anti-theft door!",
Lin Cheng nodded, knowingly said: "No problem."
Having said that, he walked straight to the anti-theft door. Lin Cheng first checked the status of the anti-theft door, and then took out a piece of wire from his pocket.
Coincidentally, this piece of wire is exactly the section that was used to help Zhou Lei open the fence gate just now.
Originally, he was going to throw this piece of wire into the trash can outside, but who would have thought that by chance, he would encounter Zhou Hua's affairs again.
As a result, this wire came in handy again.
Lin Cheng even doubted whether this food delivery system had the ability to foresee the future, otherwise, why was it such a coincidence that he had just obtained the lockpicking skill, and as a result, he encountered two consecutive incidents of trying to pick the lock.
Under the watchful eyes of everyone, Lin Cheng broke the tip of the wire into a special shape with his fingernails. This shape is somewhat similar to the head of a cobra, which is triangular.
After finishing these, Lin Cheng poked the tip of the wire through the keyhole.
Seeing Lin Cheng's actions, Jiang Fan, who was the most curious among the anti-narcotics police, suddenly asked curiously: "Brother, what is the purpose of bending the wire into that shape?"
Watching Jiang Fan ask a question, Zhou Hua frowned suddenly.
He wanted to scold Jiang Fan for not being able to distinguish priorities, and now that the situation is so urgent, this kid still has the time to ask questions.
But in the end he still didn't say anything.
Because Zhou Hua found out that after Jiang Fan raised this question, not only him, but many young people in his team couldn't help looking at Lin Cheng, with curiosity shining in their eyes.
To be honest, even Zhou Hua himself was somewhat curious about the answer to this question.
Although their police force has relations with many locksmiths, if they need to open the door when they are on missions, these locksmiths will come in handy. .
However, even if those masters pick the lock, they still use tools to complete it, and the process is quite satisfactory, there is nothing novel at all.
But this delivery boy is different. Although he also picks the lock, he only uses an ordinary wire, which is really too rare.
In a job like Zhou Hua's, they usually come into contact with people of all levels and teachings, so naturally they have seen some thieves use wire to pick locks.
But which locks are just the most common padlocks, as long as you know the internal structure of the padlock, and then practice a few more times, let alone those thieves, even Zhou Hua can pick a padlock open.
And what about the delivery boy in front of him?
Although he also picks locks, although he also uses iron wires, don't forget, what he is picking now is the lock of the anti-theft door!
The internal complex structure of the lock head of the anti-theft door far exceeds that of ordinary padlocks.
What's more, Lin Cheng just said that what he is prying now is not an ordinary anti-theft door, but a specially modified anti-theft door, and the difficulty of prying it open has doubled.
It is precisely because of this that Zhou Hua couldn't help becoming curious after hearing Jiang Fan's question.
How did he manage to pry an extremely strong anti-theft door with an extremely leaky iron wire, and what is the principle?
It turned out that Zhou Hua was a little worried about whether this question would distract Lin Cheng.
However, after Lin Cheng started to answer the questions, Zhou Hua didn't say anything anymore, because he had seen that while he was explaining the principle, the movements of his hands seemed to be faster.
Lin Cheng's eyes were fixed on the iron wire in his hand, and at the same time he said in a low voice: "Generally, the lock cylinder inside the anti-theft door has two gears and three locks, that is, the key rotates once, the lock bolt moves back one gear, and the key rotates twice. The deadbolt retreats two gears, and continues to rotate to drive the oblique tongue to retreat, thus opening the door. The reason why I bent the tip of the iron wire that way just now is actually very simple, and it is nothing more than hoping that the tip of the iron wire can buckle the anti-theft door the deadbolt, and then use the power of the wire to turn theTurn to complete the steps to open the anti-theft door. "
After listening to Lin Cheng's narration, everyone couldn't help but nodded.
Lin Cheng's explanation was fairly easy to understand, and most members of the anti-drug brigade already understood the principle of unlocking.
A few younger people have even begun to think about trying the security door of their own home after this task is over.
Seeing the eagerness on the faces of his subordinates, Zhou Hua shook his head helplessly.
If it is really that simple to pick a lock, then people who know how to use a wire to pick a lock will not be so rare.
Obviously, although Lin Cheng told them the principle of unlocking, it is not so easy to actually unlock it.
For example, most people know that atomic bombs are made through the principle of nuclear fission, but in the whole world, how many people can make nuclear bombs?
This is the truth that is easier said than done.
Pat!
Suddenly, a strange sound came from inside the security door.
"Little brother, what is this sound?" Zhou Hua asked a little excitedly.
Lin Cheng smiled slightly, and said: "This is the sound of the lock tongue retreating. Because I use iron wire, it is slightly different from the sound of the key opening the door."
Pat!
Just as Lin Cheng was speaking, the same voice sounded again.
Hearing the same voice again, an expression of excitement appeared on Zhou Hua's face.
He remembered clearly just now that Lin Cheng said that the lock cylinder inside the general anti-theft door has two gears and three openings. As long as the deadbolt is reversed by two gears, then the distance to pry the anti-theft door is already very close.
Now that the two deadbolts have retreated, doesn't that mean that the anti-theft door will be opened soon?
Thinking of this, Zhou Hua's hand subconsciously touched the pistol on his waist, and at the same time he asked: "Little brother, is the door lock about to be opened?"
Lin Cheng shook his head and said, "It's far away. The lock of this anti-theft door is unique, and its internal structure is far more complicated than that of ordinary anti-theft doors. But you don't have to worry, since the deadbolt has been moved back two steps, then The following work will be simple." (Remember the website URL: www.hlnovel.com
