A new police officer joins the team and solves a major dismemberment case

Han Xu paused and continued, "One type of lock is quite complex. It can be said to be a combination of craftsmanship and skill. The key is to incorporate the wisdom of the ancients into it. Not only is the appearance beautiful and elegant, but the inside is also complex and exquisite. There are many mechanisms! Even if ordinary people open it, some even give you the key, but they are still confused and have no idea how to start. "

"Damn it, it's so ridiculous?" Li Le became more and more confused as he listened. He didn't expect that such a small lock contained so many things.

Lao Zhang was also excited after hearing this, so he just had to give it to Li Lelai again.

Han Xu chuckled, "No, the suspense is still behind. According to relevant records, the mechanisms inside some locks are extremely complex. According to the shape and mechanism design of the secret door, it can be divided into two types: exposed locks and concealed locks. Orange What he held in his hand was not actually a hidden lock.

After all, there is still a keyhole outside.

This kind of lock that can clearly see the keyhole is also called an exposed lock, and it is relatively easy to open. But the hidden lock is different. At first glance, there is not even a keyhole in the whole body, and you can't even tell that it is a lock. It is quite interesting.

Secret door mechanism locks like this one are divided into maze locks, chain locks, and even more bizarre three-palm locks, etc.

In that industry, the labyrinth lock is the most popular, which can be said to be a masterpiece of the world. The simplest and classic labyrinth lock is designed with many ingenious secret door devices inside the lock. The keyhole cannot be seen at a glance, thus allowing ordinary people to There is no way to unlock it. "

"Damn it, there are no locking holes, so how do you open this thing?"

Li Le couldn't hold it back and played the role of admiration again.

Han Xu smiled again, "Most of those hidden locks have a lock cylinder inside, and their main bodies are mostly composed of one or more lock posts. The number of lock posts in each hidden lock varies. To put it simply, , that is, the more lock posts on the lock core, the more complicated the steps to open the hidden lock will be!

Never underestimate the wisdom of the ancients, it is quite scary.

I have seen a movie before, where there is a maze lock, which even requires two keys to cooperate with each other, one looks like a crab claw, and the other looks like a wishful thinking.

After the two keys were inserted into the keyhole together, an extremely complicated technique was required to successfully open the lock. "

"Tsk, tsk, the more I talk about it, the more suspenseful I am."

"But I estimate that no matter how Xuanhu is, there is no Xuanhu as good as the lock in Cheng Zi's hand!"

Han Xu glanced at the orange next to him again with his peripheral vision. As a result, the guy remained the same, but he no longer tinkered with the iron knot. Instead, he raised his chin with one hand, as if he was thinking about something, and sometimes frowned. , and sometimes giggle...

Good guy, I'm completely obsessed!

Li Le was startled when he heard Cheng Zi's giggle. He was about to say something, but was stopped by Lao Zhang.

"Li Le, please keep your voice down, and don't interrupt Chengzi's epiphany, otherwise this kid will come back to his senses and break your other foot!"

When Li Le heard this, he quickly shut his mouth. Good guy, with Cheng Zi's violent temper, what Lao Zhang said is true!

"I looked at the iron bump on Chengzi's arms. It doesn't look like a hidden lock," Li Le took the opportunity to change the subject.

Han Xu shook his head, "I can't tell. Although this thing has a keyhole, it is too small. Instead, it is more like a secret lock. I just don't know how complicated it is. But looking at Chengzi, it must be like this." The internal structure of the lock is amazing!”

Lao Zhang had tinkered with the machine lock before, but he didn't see the reason at all.

If Han Xu hadn't said it was a lock, he would have thought it was just an iron bump.

And he's very cunning, so I'm afraid he's not sincere.

"Okay, this guy has been tinkering with it for a long time. It's probably going to be quite difficult. Don't even think about opening it easily!"

Li Le couldn't help but conclude again.

But this mechanism lock can be said to be extremely important physical evidence.

It cannot be opened with violence. There may be some complicated design inside that can destroy the things stored inside.

So Han Xu could only place his hope on Chengzi, the magical locksmith.

Not long after the car drove, Yongxi Town had already entered the sight of several people again.

However, Chengzi was still the same as before, and Han Xu didn't know how to communicate with him.

Fortunately, Cheng Zi suddenly slapped his thigh and let out an "ah" sound!

Good guy, no matter how big the space is, the raptor can't handle howling so suddenly.

Li Le, who was sitting in the back seat, was so frightened that he almost jumped up from his seat.

"Damn it, Cheng Zi, you're going to die, you were so shocked!"

Chengzi ignored Li Le completely, but his eyes became much clearer. He turned to Han Xu and said, "Han Xu, where did you find this mechanism lock?"

Oh, my dear, I have intermittent amnesia!

In other words, since embracing this iron knot, people have drifted away from the world and entered the second dimension?

"I'll go, Chengzi, didn't you listen to a word just now?"

Even Lao Zhang was shocked. He had never seen a person with such an exaggerated concentration.

Chengzi turned his head in confusion, "Hey, Brother Zhang, when did you get in the car?"

Ah!

Lao Zhang:......

Li Le looked at Chengzi, then at Lao Zhang, and finally couldn't help holding his belly and laughing out loud, "Chengzi, can you stop being so funny? You're going to kill me with laughter!"

Lao Zhang shook his head, unable to do anything with the two living treasures.

Han Xu was still rational enough and couldn't help asking, "Chengzi, have you researched anything?"

"You're talking about this lock, you haven't told me how you got it yet," Chengzi couldn't help asking about the origin of the lock.

Before Han Xu could say anything more, Lao Zhang replied concisely, "Chu Yuntai's relics."

When Chengzi heard that this thing was Chu Yuntai's relics, he frowned and muttered in a low voice, "It shouldn't be, how could this lock be left here? No..."

"Chengzi, what are you mumbling about?" Li Le asked bluntly.

Chengzi came back to his senses after hearing this, pretending to be mysterious, "Do you know where this thing came from?"

"Hey, when did you learn to keep people in suspense? If you have something to say, say it quickly, if you have something to say, fart quickly, why are you talking so much nonsense!" Li Le didn't tolerate Chengzi, and he started to talk nonsense!

Chengzi glared at Li Le fiercely, and then slowly said, "If I'm not mistaken, this thing is called Nine Mandarin Duck Interlocking Core!"

"What the hell?" Li Le didn't react at all when he heard it, "Wow, there is such a long name? Chengzi, you didn't make it up randomly, did you?"

"These are all things that have been passed down in an orderly manner. This kind of lock belongs to the northern lock, and the design is grand and majestic, unlike the southern lock, which pursues a delicate and exquisite design!"

An expert knows whether it is true or not as soon as he speaks!

"Nine Mandarin Duck Interlocking Core? Is there any other name for this thing?"

Han Xu couldn't help but ask.
