Siheyuan: Rebirth of a comfortable life starts with Shazhu

He Yuzhu thought that in his previous life he was the ancestor of all thieves.

He can open 80% of the locks in the old courtyard alley with just a wire and a hairpin.

Of course, in that kind of situation, he needs a quiet space and time to listen to the noise.

To put it simply, unlocking relies on a precise hearing ability to hear the different sounds made when a wire is moved inside the lock cylinder.

Then you also need a sensitive sense of touch, holding the wire in your hand, to feel where the difference is, and finally find the only loophole left by the designer.

But this was truly the first time He Yuzhu had ever seen someone pick a lock with a strand of hair.

Damn, this has increased the difficulty by hundreds of times.

Old Man Shi performed a slow-motion video for He Yuzhu and the others.

To put it simply, it's a very simple matter.

People like them buy and study all the locks on the market.

They already know exactly where the lock cylinder switch is.

So, when he unlocks the lock, he simply uses a strand of hair to make a loop, inserts it inside, and activates the mechanism that unlocks the lock—that's all.

"...Ordinary locks before liberation only relied on the spring plates inside for operation."

So, by using a single tool to test the feel of each notch and moving the springs, you can align all the notches.
This type of lock has a simple internal space and stress points.

With just a little skill, you can separate a single strand of hair.

····
"The pin tumbler lock is a little more difficult, but that's about it. It's just a matter of adding a hacksaw blade at most..." Old Man Shi said happily, but suddenly a rather thin and long hacksaw blade emerged from his sleeve.

That hacksaw blade was clearly specially processed.

It's long and thin, hidden in the sleeve, so it's really hard to spot.

Anyway, Lao Xia's face has turned as black as charcoal.

After finishing speaking, Old Shi belatedly looked at Old Xia and said with an awkward smile, "Leader Xia, don't worry, I don't have any other hobbies, I just like to study these things."

To be honest, I was adopted by my master when I was six or seven years old, and I've made a living with this skill ever since.

Picking soap from boiling water, retrieving copper coins from a pot of boiling oil...

I rely on this skill to earn a living...

I only just saw the liberation of the new country.

Since liberation, I was arrested and imprisoned for more than ten years, and I haven't been able to make a living this way.

"After I got out, I preferred to paste matchboxes rather than do this kind of thing again..." Old Man Shi hurriedly explained to Old Xia, afraid that Old Xia would misunderstand him and send him back in.

"Hmph..." Old Xia snorted coldly, but did not bother to argue with him anymore.

What's there to fuss about?
He's retired.

As for Old Man Shi, the fact that he was willing to perform these skills in public shows that he has truly reformed.

He Yuzhu coughed lightly before saying, "Master Shi, let's go to the factory and take a look."

Let me share my thoughts with you again. ......

"I was thinking of designing our locks with three or five locks."

First, there's the standard door latch, the angled latch, which can be reinforced with an additional square latch for added safety.

Safety latches at the top and bottom, safety latches on the left and right, ...
They all need to be protected by a lock cylinder.

····
"That's what you need to worry about." He Yuzhu was referring to the working principle of mechanical locks in the 1980s and 90s.

It's not that he hadn't seen something more advanced; he had actually seen one in his past life, in Lou Xiao'e's hotel manager's office.

But mechanical locks are sufficient for now.

Besides, no matter how advanced Old Man Shi's lock-picking skills are, he has only seen so many lock cylinders.

If you explain it in too advanced a way, people might not be able to understand it.

"I have only one requirement: the lock you designed cannot be opened by most petty thieves on the street using things like wire or toothpicks."

Just tell me your theory, and I'll arrange for a few fitters to work with you.

Don't worry, I keep my word. As soon as the new lock comes out, I will fulfill everything I promised you.

If you don't believe me, you can have your descendants come over now.

"I'll temporarily assign him a temporary job..." He Yuzhu made too many promises that day. There was no other way; talented people are hard to find.

A top-notch thief is at least as good as a skilled locksmith, though slightly less so than a top-notch designer.

But that's enough to be considered equivalent to a senior technician in a typical lock factory.

That's pretty good.

A school-run factory couldn't even hire a fitter with a skill level of six or above.

Not to mention having a senior technician permanently stationed at the factory.

This is not to say that a technician is better than an eighth-grade fitter.

One is the chief designer, the chief dismantling planner...

The most important skill for an eighth-level fitter is manual dexterity.

Therefore, once a fitter reaches a high level, they can take the technician exam.

However, no technician was thinking about taking the fitter's certificate exam.

"Boss, it's a deal!" Old Shi's eyes lit up, and he stretched out his hand to He Yuzhu.

"A promise is a promise!" He Yuzhu said with a light laugh, extending his hand.

The next day, Old Man Shi brought He Yuzhu a small bean.

It really is a little bean.

Although He Yuzhu's school recruits students nationwide,
But in reality, most of the applicants are from the surrounding areas of Beijing.

Nobody else knows that there is such an academy in Beijing!
So while everyone's height wasn't as exaggerated as that of young people in later generations, it wasn't short either.

For example, Liu Sheng's wife is less than 1.5 meters tall, making her the shortest person in the school.

Not only teachers, but students also often ridiculed her.

But the one that Comrade Lao Shi brought today is just as bad as Liu Sheng's wife.

She was about the same height, but a bit thinner than Liu Sheng's wife.

She does resemble a smaller version of Guo Shumiao.

The reason it was compared to two women was because Old Shi brought a tomboy and a little girl.

His face was a mess, like it had been smeared with soot from the bottom of a pot.

Delicate features, tattered clothes...

She has no feminine characteristics whatsoever.

"Principal He, this is my granddaughter."

Her father was originally my apprentice, and her mother was my goddaughter.

I only found out a few years ago, after I got out of there, that her parents had already passed away.

Don't worry, although I taught her a lot of skills, I never allowed her to do anything petty or despicable.

The child is still clean.

She's fifteen this year, I beg Principal He, could you please give her a bite to eat?" Old Man Shi's eyes reddened when he spoke of the tomboy's parents, whether he was acting or genuinely sincere.

It's probably another tragic fate!

Looking at the girl with the bowl-cut hair and oval face standing in front of him, He Yuzhu asked softly, "What's your name?"

"Xiao Xiaochong!" the girl whispered, her head bowed.

"Hehe... How can a girl be called that?"
Old Shi, you should think about changing your granddaughter's name.

"Otherwise, how will I find someone later?" He Yuzhu laughed.

He liked this shy girl.

Not only is she beautiful, but she's also incredibly shy.

She's even more shy than Guo Shumiao was when she was a child.

He looks very refined. (End of Chapter)
