Cao Fu.

When Li Tai found Cao Ze with the broken watch, Cao Ze was directly confused!

it!

Are you a second ha?

I let you play with the watch, didn't I let you play as if you were dead?!

Seeing Cao Ze's strange face, Li Tai's heart suddenly sighed!

He was curious about how the watch worked, but he ignored the value of the watch itself.

This thing is so delicate and complex, it must be worth a lot of money, right?

The immortal master's expression now, shouldn't he be angry......

Oops......

If this is stabbed to my father, I seem to be unlucky......

……

"Immortal Master, I was so curious before...... Li Tai said embarrassedly, "So I couldn't hold back for a while......"

"It's fine." Cao Ze waved his hand: "Just ask whatever you want." ”

"Immortal Master, you're not angry?" Li Tai was obviously stunned: "This thing is so precious......

"Since it's sent to you, it's yours." Cao Ze said speechlessly: "Tell the point." ”

"Immortal Master, this watch is moved by this thing inside, right?" Li Tai hurriedly went straight to the point: "It's just that I still don't know how it works. ”

"How did this thing bounce back when it was pressed down and bounced back?"

"What are the things that are fixed in these little holes, and how should they be removed?"

"And the material of this watch part looks like iron and non-steel, what is it made of?"

……

Li Tai boring a lot of problems came out.

"It's called clockwork." Cao Ze explained one by one: "The ones in the small holes are called screws, which are fixed. Don't think about the material, Datang can't make it now......"

After listening, Li Tai was stunned.

It turns out that this watch is moving by taking advantage of the elasticity of the mainspring......

"Immortal Master." Li Tai continued to ask: "Although Datang doesn't have such good materials now, if I replace it with other materials, can I imitate this thing?" ”

Li Tai feels that the working principle of the watch does not seem to be complicated.

The material is not satisfied, which does not prevent him from making a low-profile version.

"Theoretically, yes." Cao Ze nodded: "But in fact, it's almost impossible." After all, such a small part can't be made by Datang now, and there is no corresponding material. ”

"And what if I make it bigger?" Li Tai's eyes were full of curiosity.

"If you make it bigger......" Cao Ze thought about it for a while: "It seems to be okay, but if the clockwork is not up to standard, the time will not be accurate at all." ”

"Time is not accurate, you can slowly debug and improve......" Li Tai subconsciously muttered.

"Then you can try." Cao Ze replied.

As for whether Li Tai can copy the watch, Cao Ze is not very optimistic.

Although the principle of this thing is simple, it is not so easy to make it.

Of course.

It's also a good thing that Lee Tae can maintain a strong interest.

"Oops!" Li Tai suddenly exclaimed.

"What's wrong again?" Cao Ze said speechlessly: "You are a dignified prince, you are always so babbling......

"Immortal Master ......" Li Tai said bitterly: "This thing has been smashed like this by me, there is no reference......"

He was so patronizing it before that he didn't pay attention to the specific size of the broken parts.

If nothing else, there must be a number of corresponding proportions, right?

Although Li Tai may not have the word proportions in his mind, the concept is still there.

The so-called difference is a thousand miles.

Without references, he couldn't do anything......

"It's easy." Cao Ze smiled slightly, and took out several watches again: "You take these back and play with them casually." ”

"Thank you, Immortal Master!" Li Tai hurriedly accepted the watch excitedly.

"By the way, you wait a minute." Cao Ze had an idea, took the paper and pen on the table and got busy.

What Cao Ze thought of was a screwdriver.

Although Datang's current technical level is enough to make such a small screwdriver, it doesn't hurt to let Li Tai try it.

In that case, let's just get out the wrenches, pliers, and whatever.

Anyway, these things will be used sooner or later, so you should prepare in advance.

After finishing the painting, Cao Ze explained them one by one.

The more Li Tai listened, the more obvious the excitement in his eyes became!

It's all good!

Li Tai's hobbies are quite extensive.

For some of the Mo family's agency news and other things, he is also somewhat involved.

After hearing the purpose and function of these tools, Li Tai immediately popped up with many new ideas in his mind.

"The things that are held in those little holes are called screws." Cao Ze pointed to the pattern of the screws and explained: "In fact, there are such a circle of protruding lines on the outside of a cylinder, which has a fixed effect by rotating. ”

It's just that Cao Ze's painting is too abstract......

In addition, what he said was a bit general, Li Tai listened to it and knew nothing about it.

In desperation, Cao Ze found an army of 100,000.

Under Cao Ze's guidance, the two carved out a rough screw model.

Well, it's really, really very rough......

It is definitely not possible to use it, but it is enough for Li Tai to understand the working principle of screws.

With the physical object, Li Tai really figured it out quickly.

I see!

It's magical!

"If you're interested, go back and study it slowly." Cao Ze handed over the model and drawings to Li Tai.

"Thank you, Immortal Master!" Li Tai thanked him and left excitedly.

Cao Ze is also very satisfied with this result.

Although I think Li Tai may not be able to make any one, two, three, but maybe.

After all, the wisdom of the ancients should not be underestimated.

Isn't that how it was before the crossing?

Many ancient things, experts have studied for a long time and have not understood the principle.

Besides, Li Tai, as a prince, definitely has no shortage of talent resources, so if he can't turn around, he will be able to surprise himself.

Not long after Li Tai left, Cheng Chumo came again.

It turned out that the sales of the watch were too good, and the shop was out of stock.

Those who arrived later were immediately upset when they saw that they were out of stock.

Fortunately, after the female shopkeeper told them that there would be new goods soon, they stopped making trouble.

Of course, even if there was a fuss before, it was just a complaint.

After all, these boys are not stupid.

You can pay the bill with chip coins, plus the sign of Cheng Ji.

Fools know who is behind the scenes.

Give them a hundred guts, and they don't dare to go wild in the Cheng family's shop......

"I've put things in the storeroom, you can let them get them." Cao Ze gestured.

After seeing the soaring turnover of grocery stores in the system interface, Cao Ze was ready.

"By the way, after selling enough for 2,000 yuan today, don't sell it yet." When Cheng Chumo was about to act, Cao Ze admonished.

"Okay." Cheng Chumo hurriedly responded.

Although he didn't know why Cao Ze did this, he didn't ask much.

The immortal master must have his reason for doing this.

Talk less and do more, that's right!

After Cheng Chumo left, Cao Ze pondered in his heart.

2,000 watches add up to just a thousand.

After deducting the cost and Cheng Chumo's dividends, it will be hundreds of times.

Although Cao Ze knew that there would definitely be more to sell when it was opened, he was not in a hurry.

Hang the appetite of those who have the rich first.

Wait for tomorrow Cheng to bite the gold and bring the goods to ferment for a day or two, and then sell it slowly.
