I Found A Planet

There is no doubt that the value of a mechanical watch with an embedded atomic clock for error correction is enormous.

Not only can it be used as a representative of high-precision products, but also provide a reference for the industrial development of country Z.

It also has high practical value.

For example, it can be used as an aerospace watch for astronauts, providing accurate time data.

Adventurers who like to participate in outdoor adventure activities, even if there is no signal or power on their mobile phones, with this watch, they don’t have to worry about not knowing the current accurate time.

Another example is in the case of getting lost, this kind of watch, in an environment with sunlight, divides the time displayed by it by 2, and then points the number to the sun, and then the direction pointed by the watch at 12 o'clock is north... It can be used This way to identify the direction.

Even if the time displayed by your watch is accurate enough, and according to some special methods and formulas, you can still calculate your latitude and longitude... This is also the positioning principle of GPS navigation in country M and Beidou navigation in country Z.

In short, as long as a precise time is provided, a lot of high-value information can be calculated.

Such a mechanical watch with great practical value, how can it be said that it is just a meaningless product for decoration and pretense?

So as expected, most of the thousands of mechanical watches piled up with gold, silver and jewelry in the Great Pit camp on Hellfa planet are high-precision watches with built-in atomic clocks.

"Fortunately, only one of these mechanical watches is lost... No!"

Chen Jin's face suddenly changed drastically.

It's over!

It seems that there is more than one piece.

In addition to the one given to Dad as a gift, there seemed to be seven or eight gold-plated and diamond-encrusted watches that were sold to jewelry recycling companies or pawn shops.

Another mechanical watch inlaid with a large sapphire from a pigeon egg was handed over to Sotheby's auction house for auction, and it was sold at a high price of more than 3 million.

what to do?

What to do with these mechanical watches that may also be faulty?

"We must find a way to get those watches back!"

Chen Jin couldn't sit still anymore, cold sweat broke out on his forehead.

He couldn't imagine that if someone saw the problem with those watches, and then launched an investigation, and finally locked them on him along the clues... He didn't dare to think about it any more.

"No matter what price you pay, those watches must be retrieved!"

So early the next morning, Chen Jin drove out early, and searched around in Shanghai City based on the remaining impressions in his mind.

Gold and silver buildings, jewelry stores, pawn shops...

As long as he still has some residual memory of these institutions he visited two months ago, he will go in and ask them.

"Boss, I sold a watch to you two months ago, is that watch still there?"

"Boss, I sold you a watch before, and now I want to redeem it, that watch is very important to me!"

"Boss, do you remember me, two months ago, I was your thing..."

For three consecutive days, Chen Jin, who was in a hurry, went to hundreds of stores that he had no memory of.

But even so, he only got back three yuan for those watches.

It cost more than 500,000 yuan, nearly ten times the price.

There may be three to four watches left. Some of the bosses said they had sold them to customers, and some said they had "processed" them... There is basically no possibility of getting them back.

The sapphire watch that was handed over to Sotheby's auction house, the other party said that according to the contract, since the item has been auctioned, it cannot go back on its word, and refused to disclose the buyer's personal information. Chen Jin had no choice but to return.

Those huge "hidden dangers" that were spread outside made him a little restless and anxious.

In order to relieve his anxiety, he did a "elimination method", trying to determine whether the mechanical watches with gold-plated diamonds that have been handed out are all embedded with atomic clocks?

You must know that gold-plated and diamond-plated watches, and the user groups who buy such watches, are by no means pursuing the practical value of the watch. The biggest purpose may be "show off".

It is entirely possible that diamonds and gemstones inlaid on the watch will take up the precious dial space, making it impossible to insert the atomic clock.

Chen Jin took the three recovered mechanical watches, went to the Dakeng camp, called the robot Dabao over, let it release laser heat to heat up, and violently opened the three watches.

As expected!

Due to the limited internal space, the first mechanical watch did not have an embedded atomic clock inside, but a conventional mechanical mechanism.

The same is true for the second and third blocks, which do not have built-in atomic clocks.

Chen Jin finally breathed a sigh of relief!

"Let me just say, these watches are inlaid with so much gold and diamonds, where is there room to put the atomic clock in? I should be worrying too much!"

But there are no absolutes, Chen Jin dare not be 100% sure that none of the mechanical watches he sold had an atomic clock embedded in them.

He had no choice but to continue to use the method of elimination to screen out all the mechanical watches inlaid with gold and diamonds from the pile of treasures.

A total of 286 yuan.

Then use laser heating to disassemble and watch the internal structure.

It was finally confirmed that 268 blocks were of conventional construction, and 18 blocks had embedded atomic clocks.

The probability that such a watch is classified as a high-precision atomic watch is ... 6.3%.

"This probability, multiplied by the 9 watches I sold, the number of atomic clocks passed down is - 0.56."

"That is to say, excluding the atomic clock that I gave to my father, there may be 0.56 atomic clocks circulating in the society."

Rounding up, it is counted as one piece. In theory, the number of people who get high-precision atomic clocks can be increased by one more person at most.

The probability of accidental exposure is quite small.

Not particularly scary.

"Besides, most of the people who buy this kind of watch are rich people, not engineers like Dad. They don't particularly care about whether the time is accurate or whether the error is large. They buy this kind of watch mainly for decoration. It's just forcing...you may not find something wrong."

Even if something was wrong, it would be very difficult for the other party to find Chen Jin, who didn't leave any personal information, through the shops in the middle.

So... the probability of an accident should be one in ten thousand.

Basically nothing.

The fluke mentality that low-probability events should not happen made Chen Jin give up his efforts to continue searching.

After all, it was too troublesome and tiring! It's pretty good that he lasted for three days.

He didn't want to devote 100% of his energy and time to a small probability event of one in ten thousand, which seemed to be worth the loss.

After all, he needs to deal with the affairs of the jewelry store.

On the other side of the Dakeng camp, the robot has recently shipped back a large amount of equipment and raw materials, and he has to start arranging the next step, such as completely solving the power shortage problem in the Dakeng camp.

Even if it really happened, he could only use soldiers to cover up the water and soil, trying his best to fool him.

...

In the evening, at the dinner table.

When Chen Jin announced that he would give up his efforts to find the stall owner.

He Li said with some distress: "Son, you have been looking for three or four days. You go out early and return late every day. You have lost a lot of weight. Don't look for it anymore! You have tried your best. Besides, you have your own career. How can you Are you busy with this kind of thing all day?"

After speaking, she put a lot of vegetables into Chen Jin's bowl.

"Okay~"

Chen Gang couldn't say anything more. He saw his son's hard work in the past few days. He ran all over Shanghai City. He really tried his best. It was not his fault that he couldn't find the stall owner.

It is completely understandable to say that I am tired now.

Chen Jin nodded calmly, and thought to himself: Dad is easier to fool.

In this way, the matter of finding the stall owner gradually faded away.

And the atomic clock stored in the precision instrument research room of COMAC eventually turned into an unsolved mystery in the history of Z country's technological development.

This chapter can be regarded as a foreshadowing, it may be poisonous and inappropriate, but this loophole cannot be completely ignored, although I want to ignore it
