The old things I repaired have become fine

Chapter 457 Yun Kun: Shen Le, wait for me, I will bring you the secret underwater realm!
"I will return!"

"I will definitely come back!"

"I'll be back in a month at most! Then I'll bring you something good!"

“Bring Haidilao!”

All the sails of Yun Kun were filled with sea breeze, and they untied the ropes and slowly left the port. On the side of the ship, a row of people stood still, trying to wave, but without making a sound;

There was a big speaker hanging on the top of the mast, shouting enthusiastically, but the voice was a bit weird, it sounded like an AI voice...

Shen Le's eyes twitched. Yun Kun, please take the person back!

That is, there are no ordinary citizens around here. If a citizen looks through a telescope and sees a row of paper and cloth dolls standing on your deck, trying to wave...

Do you think people think you are scary or that you are a robot?
Also, it takes three years to learn good things and three days to learn bad things. Before, I could only let the puppet hold the tablet and type, then poke it in front of the person to let the tablet play the voice;
Now, the puppet can hide in the cabin and type, and the voice is played on the loud speaker, pretending to be a person hiding in the cabin and talking...

Shen Le also put a lot of thought into Yun Kun's growth. He spent a whole month accompanying Yun Kun in class:

Attend general knowledge classes, ocean surveying classes, underwater cultural relics exploration and identification classes, navigation classes, and even many military courses.

Well, there is no need to train Yun Kun to be a soldier, but at least he must obey orders and enforce discipline. If you run around recklessly, you will implicate many, many comrades. This should be engraved in Yun Kun's bones!

To be honest, this is not difficult. Yunkun is a Ming warship after all. As long as you make it clear that "you are a soldier and you must abide by military law", the little guy will obey.

Of course, Shen Le only needs to attend a small part of the course, but Yun Kun has to attend the course in three shifts:

The Special Affairs Bureau also invested heavily, hiring teachers with high salaries to teach Yun Kun 24 hours a day.

Fortunately, Yun Kun was a spirit, so he could withstand such high-intensity indoctrination. If it were a human, he would have been mentally broken and completely crazy. Only Yun Kun was still shouting happily:
[I understand! I understand! ]

【I can play this instrument now! 】

[Hey, this is so interesting - if I knew this earlier, I wouldn't be afraid of getting lost when I'm sailing on the sea! ]

The first half of the month was spent on tutoring on the shore, and the second half of the month was spent going out to sea for tutoring.

Poor marine surveying experts, they had to work in three shifts to tutor Yun Kun, huddle in the cabin to work, and at the same time, they had to endure the shattering of their three views:

[Use sonar to scan the seafloor? Why use sonar? I can see it! ]

[Look, this is the situation on the seabed! ]

Yun Kun was responsible for "seeing", the compass was responsible for positioning, and the scroll was responsible for projecting light and shadow. As soon as the light and shadow appeared, the chief surveying and mapping expert who was responsible for teaching Yun Kun made a "click" in his throat and almost fell backwards:
This is a three-dimensional image!

This is a three-dimensional image of the seabed!
It’s even colorful!
The data sent back by the sonar needs to be calculated and the signal needs to be sorted and deformed according to various conditions such as distance, signal, etc. before the result can be obtained.

And what Yun Kun projects is simply an image, which is roughly equivalent to dragging a camera to take pictures on the seabed!
"Record it quickly!"

Shen Le held the professor and turned to shout. Everyone seemed to be awakened, and they were in a panic and worked hard:
He held up the scroll respectfully and carried it to the special room next door;

The instruments on the four walls of the room were turned on to scan the light and shadow cast by the scroll, and the three-dimensional images were recorded into the computer;
At the same time, he put on a smiling face and respectfully asked the wooden boat:
"Mr. Yun Kun, how far can you see? Can you show me your maximum detection range?"

[I’ll give it a try…]

Yun Kun was silent for a while. After a while, the image reflected by the scroll began to blur, blur, like a drop of ink dripping into a clear basin of water:
The ink-spreading picture kept shaking. On the upper layer of the picture was a detailed sea map. Although it was just a blue area, it at least had longitude and latitude grids to mark the location.

At the bottom of the screen, the previous three-dimensional image keeps shrinking, and the seabed image next to it keeps appearing. The further you go, the blurrier the image becomes, and the larger the mosaic grids become;

However, no matter how blurry it is, it is better than the three-dimensional restoration image made by sonar feedback!
That thing basically relies on guesswork and imagination, which is even worse than a sandbox. It would be so great to have an image that can be "seen" directly...

"Alas, it's too small..."

A group of people rushed to look at the map and count the longitude and latitude grids. After counting, they sighed:

"Only two nautical miles, it's too small..."

"Today's sonar, active sonar, can detect up to 30 to 35 nautical miles, and passive sonar can detect up to 60 nautical miles!"

"Yun Kun, can you try harder and look farther? Two nautical miles is too close. By the time we get to two nautical miles, the other party will have already run away!"

Yun Kun turned around and around in the sea. Sometimes he floated on the surface, sometimes he sank into the water. As he turned around, he complained:
[Who told you not to let me have enough spiritual energy! ]

[As long as I eat enough, I will definitely be able to see far! Very far! I won’t be laughed at by them! ]

[If you don't let me eat, I definitely can't do it! ]

[The emperor has plenty of hungry soldiers! ]

Not only did it complain and get angry, it also refused to work. The experts could only glare at Shen Le and criticize him:
"It is! It is!"

"Who told you not to let him eat enough!"

"What's wrong with eating a little more? It's not like we can't afford it..."

"Look how hungry the child is! Don't ever do this again!"

While accusing, she winked and winked. For a moment, Shen Le felt a sense of absurdity, "Dad doesn't give you food, Dad is bad, grandma beats Dad to vent your anger - look, she beats you."

He had no choice but to turn a deaf ear to it, patted the wooden boat wall, and soothed it softly:

"Okay, okay, next time we go to that secret place, I'll tell them to let you take in more spiritual energy and eat your fill. As for now - focus your attention and look in one direction?"

With omnidirectional scanning, if the diameter is two nautical miles, and you look in one direction, the distance may be able to reach 5 nautical miles, 10 nautical miles, or even more?
"Also, it's okay if the accuracy is lowered a bit... How accurate does the sonar scan need to be? At a distance of 20 nautical miles, do you need to be able to recognize a ship? Recognize a submarine?"

He turned to the group of experts. Among the experts, the one in charge of military sonar took a step forward and shook his head vigorously:

"Then the accuracy should be higher, and it should be able to display the speed in real time - for example, a torpedo?"

That's true. Shen Le patted the wooden boat wall:
"You heard me, right? As long as you can recognize the torpedo, that's all. By the way, how big is the smallest torpedo?"

"The smallest in history is the A200, with a diameter of 123.8 mm and a length of 883.4 mm..."

[Then the accuracy still needs to be very high...]

Yun Kun tried it while crying. The experts sighed and started to work:
To analyze the information collected by Yunkun;
We need to continue the experiments on board;
I have to continue teaching Yun Kun:
"You not only need to be able to 'see', but also be able to read the picture! For example, the horizontal line here and the horizontal line here look very similar, but what do you say they are?"

【What? 】

"This horizontal line is obviously the mark left by the anchor chain, and this horizontal line is the submarine optical cable... No! Wait! Don't touch it! If you damage it, something terrible will happen!"

[Is it not okay for me to touch it? I will know if I touch it...]

The expert was helped down to massage his chest, pat his back, drink water, and take a quick-acting heart-saving pill. An expert from another direction followed up and took over the teaching of Yun Kun:

"No, just being able to 'see' is not enough! For example, in this section of the seabed, in the canyon between two raised mountains, we need to measure its flow rate, which is very important for submarines...

Here, this laser Doppler deep-sea current velocity measuring instrument, show me how to use it..."

[But why do I need to learn how to operate these instruments? Don’t you have a pole for measuring current velocity? Give it to me, I’ll stick it into the seabed, and I’ll retrieve it after a while!]

The expert almost fainted for the second time. Speaking of these deep seas, straits, and rapids, we wanted to insert Doppler measuring instruments into them, but we couldn't dive down!
The only submersibles that can dive down there are a few like the Jiaolong. When they go out, they make a huge noise, and the whole world is watching...

So you can go down?
Is it easy for you to go down there?

The "pole" does exist. The domestically produced self-contained storage current meter has high accuracy, long endurance, and large capacity.

As soon as Yun Kun shouted, someone immediately brought him a bunch of them:
"So how are you going to get it in?"

[Tell me where to insert it! ]

"Well, I'll teach you once, and you'll know what to do next time. Come, do you see that trench down there?" The expert steeled his resolve and started to ask for a big idea:
"Insert one at the far left, far right, and in the middle of the trench entrance. Then, follow the trench inward and insert one every 500 meters. If there are less than 500 meters, insert one at the bends..."

With a swish sound, a water shield rose above Yun Kun's head and pressed down at full speed. As he dived downward, he quickly became smaller and smaller.
At the same time, a group of puppets in the cabin took the current meter and ran to the deck.

Even a white cat jumped up lightly, snatched a pole from the expert's hand, landed on all four paws, and ran briskly.

He jumped over the puppet's head and shoulders, climbed up the stair railing, and even surpassed the puppet, and was the first to run onto the deck:

"mum!"

A cable was thrown out from the edge of the deck, entangled the current meter, and was thrown out and penetrated deep into the seabed.

The end of the cable suddenly spread out, breaking into seven or eight hemp ropes, which moved flexibly like octopus tentacles, fixing the current meter:

[Okay! Next!] Experts: “…”

This, this job is really beyond the limit... This cable is easier to use than the robotic arm on our submersible!
Yun Kun was very happy, sometimes rising to the surface of the sea and sometimes sinking to the bottom of the sea. The experts had to concentrate all their energy and work hard, but for Yun Kun, he just treated it as a game.

Not only can it scan inch by inch and display the changes in the seabed topography inch by inch, but it can also catch a few fish from time to time and throw them onto the deck to provide a snack for the experts.

Even, from time to time, it sits down on the seabed:
[Hey, there's a boat here! Do you want to fish it out? It's an ancient boat! Shen Le likes it! ]

Shen Le: “…”

You get up first, float up a little bit... If you sit down, we won’t be able to see the boat!

The military experts temporarily went offline to sleep. The marine cultural relics research experts, mainly the doctoral students, were urgently awakened and went online to work:

"Raise yourself a little first! Give us a full picture! Yes, give us a full picture... Tsk, now we can see it clearly, it is indeed a sunken ship, it is divided into three sections..."

"Come on, can you salvage some? First salvage some targeted items, such as intact boxes, or things scattered outside... No! Wait!!!"

There was a splash of water. On the deck, a long cable broke through the mud and flexibly wrapped around a box.

Halfway through the ascension, the box broke into pieces, and the contents inside it fell onto the deck like flowers scattered by a fairy, smashing into pieces on the spot...

"Wait a minute!!!"

The doctor's heart ached. He rushed forward bravely, slid directly onto the deck, and hugged a ball of... something that fell from the sky:
"Yun Kun! Yun Kun, stop! Don't throw things around! Put them down gently...

No, forget it. We'll prepare a box for you. You can put the salvaged things in the box and then carry them up, okay?"

Shen Le was trying to hold back his laughter and sighing beside him. Alas, Yun Kun is just a child!
When you let him do the work, you must talk to him carefully and provide him with guidance on every detail!
Now, he has done everything you need to do. The box is broken because of its strength, and the child doesn't understand...

The doctoral student covered his face and sighed.

A group of doctoral students who were engaged in the salvage and restoration of marine cultural relics had to put on gloves and go to the deck to pick up the cultural relics.

While taking photos, picking up the pieces, numbering them one by one and putting notes on them for record, I was also tutoring the wooden boat:

"After being submerged in the sea for hundreds of years, the strength of a sunken ship would become very poor...very fragile..."

"Things that sink to the bottom of the sea will quickly oxidize and decay if they come into contact with air..."

"So, we usually use special salvage boxes, pack the cultural relics and the boxes together, even with the silt and seawater, and bring them out directly...

Bring it to a laboratory with cultural relics preservation conditions, and then carefully open it to avoid damage to the greatest extent possible..."

[Yeah, yeah, I get it... ah! That! That thing has fallen off! It has fallen off!!!]

"The dust has fallen off because it has oxidized... Look, it turned out to be such a beautiful color... So remember, when you salvage underwater cultural relics in the future, you must pack them up before you salvage them!
Otherwise, the beautiful ancient artifacts you wanted to give to Shen Le will be gone and turned gray... We used to send large ships to pack the sunken ships on the seabed and bring them back..."

[Yes! Yes!] Yun Kun kept agreeing, obviously taking all the words in. After listening to a lecture, he suddenly shouted happily:
[I understand! Then can I salvage it this way? ]

There was another splash. This time, a stream of water, carrying a new box, rose slowly from the mud.

The water outside the box swirled rapidly, forming a circle. Near the box, a crystal clear, quiet water ball enveloped the box. Even the seaweed growing on the outside of the box did not move...

The water ball rose from the seabed to the edge of the deck, breaking through the crystal clear water wall and landing directly on the deck. The two doctors hurried over with the box to receive it:
"Alright, alright! That's all! Yun Kun, come, put the box down..."

The water flowed like a thin, crystal-clear ribbon, suspending the water ball high in the air and placing it in a special cultural relic storage box. Then, the water level in the box slowly rose, slowly rose, and slowly rose...

"Alright, alright! Enough, enough, enough!"

The water flowed down slowly, filling the entire box. Then, a long stream of water remained on the top, which suddenly rolled up and plunged into the water wall and disappeared.

"Ah, Yun Kun is so capable... so well behaved..."

The doctors went up to cover the box, locked the lid, and carried the box to the cabin. As they walked, they also tried their best to flatter the wooden boat:
"This salvage method is much more efficient than using a professional salvage ship, sending frogmen down to fix ropes, and measuring, calculating, and verifying beforehand!"

[Hehehe... Hehehe! Am I very good? Am I very good? ]

Yun Kun laughed so hard that the sails of the boat moved without wind, making a rustling sound. After a while, the loud speaker on the boat suddenly raised the volume. God knows how it learned to increase the volume to express "raising the voice":
[I have a special trick! I can take this wooden boat back with me! Let’s go——]

The sound of water roared. On the underwater scene projected on the scroll, a crystal clear water dragon rose up around the boat and dived down -

The water dragon circled, completely wrapped around the hull of the sunken ship, and suddenly lifted it up. The seabed was filled with mud, seaweed, small fish and shrimp.

Through the screen, everyone even felt that they could hear the "creaking" sound of the sunken ship breaking apart...

"Wait! Yun Kun! Stop for a moment!!!"

Shen Le couldn't bear to watch it anymore. The broken planks of the sunken ship were equivalent to the destruction of cultural relics, which would bring countless troubles to future workers.

It's like cutting his flesh and digging out his heart and liver!
"Just mark this place! We can come back to fish it out later!

Once the artifacts we just fished out have been appraised and it is confirmed that this ancient ship is valuable, we will bring a large ship to fish it out and preserve it and take it away directly!"

[But, if you come back to fish it out again, it won’t be yours anymore…] Yun Kun hesitated:
[A ship is worth 3000 billion US dollars! 3000 billion! ]

"No, Yun Kun, I'm really not that short of money..." Shen Le didn't know whether to laugh or cry:
“It’s not that I don’t want so much money, but if I really had 3000 billion, I wouldn’t know how to spend it…

And these are just numbers on paper! Have you forgotten the numbers on paper? You can’t sell them for cash!”

After much persuasion, reasoning, coaxing, and praising (yes, Yun Kun still has a childish personality, so he should be praised), the little guy was finally calmed down.

The cultural relics experts on board the ship started working urgently, sorting, cleaning and identifying, and the final result was that this was a merchant ship from the Qing Dynasty...

"And the artifacts inside are not of high quality. I'm sorry, Mr. Shen, but you can't make a fortune from this shipwreck alone."

It makes me sound like I'm going to get rich salvaging a sunken ship... Shen Le rolled his eyes silently. He wasn't disappointed, but Yun Kun was very disappointed, and he whimpered for a long time. Shen Le had to comfort him:
"It's okay, it's okay. If we find a good shipwreck in the future, we'll salvage it. Most importantly, if we come across an ancient artifact with strong spiritual energy in the future, will you salvage it for me?"

[That's absolutely no problem!] Yun Kun was finally happy:

[Look at me! Not to mention spiritual objects, I will find you one even if there is a secret place under the sea! ]

During this trip to the sea, the world views of all the experts, military personnel, and special affairs bureau personnel were greatly changed.

When they finally returned, the experts who worked in three shifts almost collapsed on the ground as soon as they got ashore. They had to get enough sleep anyway:

How nice it is to be on shore!
How wonderful it is to be alive!
So many people were cramped in a 400-ton wooden boat, with half of the space to store instruments, supplies, and equipment, and it would dive to the bottom of the sea from time to time...

You also have to adapt to "a ship that can talk, a ship that can dive, a ship that can sail itself, a ship that can do things that you humans can't do..."

Even if you have been informed beforehand, being informed is different from seeing it with your own eyes and experiencing it in person, right? !
Although the personnel from the military and the Special Affairs Bureau have stronger wills, they also have more to adapt to in terms of professional skills, and they look exhausted at the moment.

Only Shen Le not only had no time to rest, but was also respectfully invited by the Special Affairs Bureau:

"Mr. Shen, we are really grateful for your help. We will certainly not be short of Yun Kun and his men's reward, and we will not be short of your reward either—"

The director of the Magic City Special Affairs Bureau respectfully picked up a large 16-page color book and placed it in front of Shen Le:
"You have previously selected several items to be restored in the Special Affairs Bureau's warehouse. That warehouse is only the outermost part. We still have many core collections for you to choose from..."

Shen Le opened the color book and the first page of the catalogue was bronzes, bronzes, bronzes, and bronzes.

Turning to the back, there are jade, porcelain, pottery, calligraphy and painting, textiles, weapons, and various miscellaneous items...

In short, all the cultural relics that Shen Le could think of were listed there. Shen Le even saw two ancient buildings:

"Why is there an ancient building here? Is it a haunted house? A haunted house?"

"It's not a haunted house, but it can run away..."

Shen Le flipped through the pages of the color book, making a clattering sound. The director gave instructions:
"This list is from Magic City. In fact, we have communicated with the higher-ups. If you are interested, you can go to the National Special Affairs Bureau's general library to take a look.

There are a lot of good things there, including a lot of old and spiritual things. As long as you promise not to resell them, you can choose whatever you want..."

Resell?

How could it be resold?

The things I repaired were all inspired by me, my own little ones. Selling your own children?
Absolutely impossible!

"Where is the warehouse in the Magic City? Take me to have a look first!"
