The old things I repaired have become fine

Chapter 566: Shen Le gets the opportunity, the research institute gets rid of the burden, a win-win situation!
Shen Le sat upright in front of the workbench, pedaling the swivel chair under his feet, turning in a circle now and then.

He moved the two workbenches very close together, leaving only a one-meter-wide aisle in between, allowing him to come and go and refer to work at any time.

On the workbench at one side was the helmet he had unearthed, placed in a special oxygen-free and water-free environment to minimize external corrosion.
On the workbench on the other side, three computer screens were spread out in a "U" shape, allowing him to observe from all angles effortlessly.

On the left screen, a large amount of information was opened, including various types of helmets from the Tang Dynasty, murals, clay figurines, and various restoration models;

On the screen in the middle, the helmet he had unearthed was opened, along with various related documents. There was a 3D reconstruction of the CT scan - and metal flaw detection was also done;
The helmet was scanned using X-ray fluorescence imaging technology, and the element distribution map was restored, with the gilded pattern outlined on the helmet;

There are also various drawings, photos, and records before...

As for the screen on the right, it is still blank at the moment. Well, the file he has opened now is still blank.

Shen Le switched the information on the left and middle screens and read them back and forth until he had a general grasp of it in his mind. Then he began to paint on the right screen stroke by stroke.

The helmet he found looked like a whole piece at first glance, but under the 3D scan of the CT scan, it showed that each of its parts were different:
A whole curved top, a curved piece attached to the side of the top, and a smaller nail piece connected to the bottom of the curved piece.

The raised ear guards on both sides of the helmet, and the stacked neck guards behind the ear guards...

Over thousands of years, they have rusted, deformed, and glued together. However, under CT scans, they have revealed their original forms piece by piece:
"Well, based on these prototypes, we should be able to infer what it originally looked like..."

Shen Le looked at the scan, drew a nail piece, looked at the scan again, and drew another nail piece.

The top, the hole on the top, the shape of the curved piece, the shape of the earmuff... draw a nail piece, copy it a few times, draw another nail piece, and copy it a few more times.

When the copies are almost complete, drag the nail pieces and stack them up one by one, making sure that the holes for threading the ropes overlap each other:

As they put together the pieces, a relatively normal-looking helmet appeared suspended in the air on the screen, rotating and flipping continuously as Shen Le dragged the mouse.

Outside the studio, several students watched through the surveillance screen, drooling with envy:

“I’m so happy!”

“One person can use three monitors!”

“Such a good computer!”

"We can only use one screen each, and our computer performance is much worse than his, and it often freezes..."

"He can ask the teacher for advice at any time! He can ask questions! We can only ask for advice when the teacher is free, or when we are doing a task assigned by the teacher and we really don't know how to do it..."

"Envy, envy, all you know is envy of others!" Professor Bai walked over with a gloomy face and slapped the most excited student - who was also his own student - on the forehead:

"You all have PhDs, but I'm still just a Master! A Master! Or a Master who started out on his own after graduation, and didn't stay in school, museums, or research institutes!"

In comparison, his own students had studied for at least three years longer than Shen Le, and had three more years of guidance from the teacher:
"People have done this kind of restoration and have done it quite well! Even so, the restoration is still a spiritual thing, and they have to work under so many interferences!"

"Also, the computers and screens they use are not owned by our institute." Another professor walked over slowly and said calmly:
"Although they are all in our office, these devices are at best just occupying our territory... The budget was provided by the Special Affairs Bureau!"

"In fact, it is also good for us that the Special Affairs Bureau puts these things... If you don't fix some things, they will continue to emit very bad fluctuations, which will harm all of us."

Professor Bai has a clearer understanding of the Special Affairs Bureau:
“However, if it is repaired, there is a certain chance that it will be able to communicate, harmonize the atmosphere, make the surrounding environment softer and more comfortable, and give back to the restorer.

——Therefore, there have always been people who risked their lives to repair these cultural relics and restore them to their original state. They were sealed up only when they could not be repaired. Now there is someone who can repair it..."

He sighed deeply, and stared at Shen Le's busy figure across the surveillance screen:

“How wonderful…”

"Well, teacher, would you like to take out some of the things that are sealed in our warehouse and have them repaired for him?"

The student couldn't help asking, "Isn't it said that it can make the surrounding environment softer and more comfortable?"

We don't expect to be supported in return, as long as we can make the surroundings more comfortable and the conditions in the institute better, at least everyone's health will be better!
"you……"

Professor Bai raised his hand, as if to hit the student. Seeing the student holding his head and shrinking his neck, he put his hand down and sighed slowly:

“There are so many things piled up in our warehouse, why should anyone help you fix it?
——Well, let’s put the warehouse in order. Take out the cultural relics that are not very valuable and are related to the restoration of armor, and the things that he might use for practice…”

"Okay, Boss! We'll be there right away!"

The students dispersed in a hurry. Those things that had been piled up in the warehouse for ten, twenty, fifty years, with seals and talismans from the Special Affairs Bureau on them, could finally be cleared out!

These things will also interfere with the electromagnetic field, making it impossible for robots to move boxes - of course, robots have not developed to this level, but they don’t have unmanned forklifts either!

They could only let these young people, wearing isolation equipment provided by the Special Affairs Bureau, go in to clean up and carry out the transportation.

Over the years, I have watched the warehouse grow bigger and bigger. It used to occupy the edge of the institute, but now it is the best location. It is not easy to move!
"Go, go, go! Get the list, get the equipment, and drive the forklift! - Hurry up, get out a batch of iron products, silk products, leather products, and linen products!"

The students went to work with great enthusiasm. Shen Le didn't know that he was about to have a lot of work to do. He just frowned at the iron helmet in front of him:

...So, where do I start?
Clean up?

Rust removal?

These things are all stuck together, it’s not easy to deal with them!

After thinking for a long time, flipping through books and papers, and consulting several old professors, Shen Le finally picked up the small brush.

The brush will still cause physical damage to cultural relics. No matter how minor the damage is, it will still cause some damage.

So, can we use cleaning techniques or mental power to clean it?
How can we ensure that when using mental power to clean it, it will not, or as little as possible, damage its body?

The sand was firmly embedded in the iron helmet and almost hidden in the cracks in the rust!
"Mr. Shen! Mr. Shen!"

Just as he was feeling embarrassed, someone knocked on the door outside, mixed with excited shouts. Shen Le stretched and stood up to open the door:
"Ah, don't be so polite. We are all majoring in cultural relics restoration. According to the time of admission, I should actually call you senior brothers?"

"I don't dare to be a senior brother. We are not allowed to work independently..." The leading student smiled brightly and pointed at the handle of the cart:
"Come on, come on. The boss is afraid that you have never repaired such rusty things, so we sent a batch over for you to practice. Go ahead and repair them. We won't feel bad if they break!"

Shen Le didn't even have to check each item one by one to feel the strange fluctuations in the boxes on the cart.

He quickly took the handle and pulled the cart into the room, while preventing the young researchers from entering:
"I'll do it, I'll do it. You know the rules of the Special Affairs Bureau. There are some places that are difficult for you to enter. It's easy to get hurt. Are they all here?"

"They're all here! - 35 pieces in total. Check the serial numbers and sign if there's any problem! By the way, except for this place where we can't enter, we can still come into contact with each other on weekdays, right? Let's go eat together after get off work?"

"it is good!"

Shen Le smiled. He would stay in this institute for at least one or two months, and of course he had to build good relationships with the local researchers.

Otherwise, it would be so lonely here! Even if you want to have a bite to eat, there are no locals to recommend you a good restaurant!

Shen Le checked the serial numbers on the boxes one by one and watched the young researchers leave. He turned around and clapped his hands:

"Come on, everyone, do me a favor and take out everything inside and keep them one by one!"

With the sounds of swishing and clacking, Huang Yutong spread out on the floor. Girls in silk skirts and clay figurines rushed out and started working one after another.

On the surface of the box, various talismans, sealing strips, and sealing tapes of the Special Affairs Bureau were densely stacked. Some were brand new, some were dull and faded, and their age varied.

It seems that the seal needs to be reinforced every few years: this is not a small project, and the budget is very daunting!

The little guys worked in groups, several by several, around the boxes, working hard. Suddenly, the sound of "sizzle", "sizzle", and the sound of tearing tape to unzip the boxes filled the air:
You have to tear off all the layers before you can open the box. It will take a long time to tear off so many seals!

[Get out of the way! Get out of the way! Follow my command!]

After tearing off the tape and the seal, the wooden box underneath was exposed, and the little inkstone immediately jumped out of the ancient house.

Brothers with their own woodworking tools pointed out:
[Pry the nail out from here! ]

【Next pry this! 】

[Very good, be careful! Smash, smash, smash! Broken? Oh, don't use brute force. These nails that have been driven in for decades will become very fragile if they rust!]

[Forget it, don't do it, I'll do it!] Chisels, hammers, claw hammers, nail pullers, all flew around, and even a saw helped.

Shen Le, on the other hand, couldn't help. He just sorted the safes one by one according to the list of items, plugging in the power supply and connecting the nitrogen to the boxes that needed to be connected.

By the way, fellow old professors, you really think highly of me - with so many cultural relics, if I don't use magic, it will take me forever to cultivate them!
Well, it's okay for me to use magic, right? Anyway, these artifacts with special energy shouldn't be placed in ordinary museums, right?
In other words, they have been relegated to a separate category from the very beginning, and orthodox cultural relic restoration institutions no longer have much hope for these cultural relics...

After opening the boxes one by one and putting the items into the safe one by one, Shen Le finally let out a long sigh.

This is the characteristic of cultural relics in the Northwest region - because of the extremely dry geographical environment, many cultural relics are well preserved and almost not decayed, which is quite rare in the Central Plains.

For example, the famous Han Dynasty brocade with the inscription "Five stars rising from the east bring good luck to China" was discovered in a site in the Hotan area.

Another example is the Astana Tombs in Turpan, where more than 400 ancient tombs from the Jin and Tang dynasties were cleared out:

Among the tens of thousands of historical relics unearthed, there are mummies, documents, silk, wool, cotton and linen fabrics, clay sculptures and wooden figurines, leather goods, fruits and food...

Some of them are basically impossible to preserve in the Central Plains!
Where in the Central Plains can you find a place with an average annual temperature of 14.1 degrees, an annual precipitation of 16.6 mm, an evaporation of more than 2800 mm, and an air humidity of about 30%!
Of course, the cultural relics sent to him now are still quite rusty, probably because there is still some water in Dunhuang - people cannot live without water.

Shen Le held out a pile of rusted metal pieces, squinted his eyes, and looked left and right. Apart from probably some coins, he couldn't see anything else:

They are big and small, thick and thin, overlapping each other, and the edges are slightly curved - not regular, probably because a lot of them were lost during the rusting process.

As for the text on it, it is basically rusted and can't be seen at all. Well, there is a lot of dirt and gravel on it, and after a long time, it has basically merged with the coin...

"Shen Le, just start with this, no problem!" The microphone in the corner of the room rang again, and Professor Bai began to give him on-site guidance:
"It doesn't matter if they get damaged. Anyway, these coins have been unearthed in large quantities all over the country, and there are also quite a few unearthed nearby. Just give it a try, try boldly!"

Shen Le sighed, put the metal sheet into the box, fixed it on all sides, and held it under the microscope. With a small brush in one hand, he held his breath and brushed patiently:
Once, twice, three times. First brush across the surface, roughly, then brush along the grooves and bumps.

When working under a microscope, if you move too much, the tip of the brush will fly off to who knows where, so you have to be extremely careful and proceed slowly;

However, it was brushed really clean. After several rounds of cleaning, the cleaned part and the uncleaned part next to it were obviously different!

The brush is very effective for loose dust, but it is completely useless for dirt that is more firmly attached. Shen Le put down the brush, picked up the specially prepared fine needle, and cleaned it carefully one needle at a time:

Instead of using a fine needle to poke and pick out the dirt, press the tip of the needle onto the dirt and press back and forth from all directions to loosen it.

Until under the microscope, you can see that their roots are loose and almost leaving the surface of the object, then move the needle tip away and use another piece of dirt to loosen it:

"I feel like my work is as meticulous as neurosurgery... In general surgery, stitches don't need to be done under a microscope, right?"

Shen Le grumbled and complained, and he also had to control the strength of his hands so as not to damage the object. Even if it was just a grain of copper rust, it was best not to drop it!
The copper rust itself is part of these coins!
He worked so hard that he was dizzy. He used a brush first, then a needle, and after the needle was loosened, he used a vacuum cleaner to clean it up:

The museum's specially equipped vacuum cleaner, with the smallest output, vacuums one square centimeter at a time, fearing that a slightly stronger wind would damage the fragile artifacts.

It takes about two hours for a hand surgeon to sew up a severed finger if the cut surface is smooth.
Shen Le was a little faster than them, but after two hours, he only cleaned a small area of less than 10 square centimeters.

Compared with the surface area of the entire pile of metal sheets, this work efficiency is so low that it is despairing.

"This efficiency is too low..."

Shen Le let out a long sigh, turned his head to look at the time on the mobile phone screen, and lamented.

He did see in the paper that a restoration teacher repaired a pair of leather shoes from the Tang Dynasty, yes, also unearthed in the northwest region, and it took several days just to clean it;

I also saw a senior teacher repairing a bronze ware. He would sit in front of the table for almost a whole day and a half without moving, and there was almost no visible progress.

However, at this speed, will it take one or two years, or three or five years to repair the entire piece of armor?

The Special Affairs Bureau always has things waiting for his help, and Yun Kun wants to go out to sea with him!

Forget it, let's try magic. Shen Le moved the metal piece under the microscope and found a corner farthest from the part that had been cleaned before.

Then, he once again lay on the microscope, held his breath, and adjusted the cleaning technique to the lowest output, about the same as when he cleaned the ancient and fragile silk and removed the dirt on the warp and weft:
"Cleaning technique! Cleaning technique! Cleaning...cleaning...technique..."

A small cleaning spell was cast, and immediately a small area under the lens became clean. The rust was still there, but the dirt had disappeared. No, it had been moved to the white paper next to it:

Very good. Although it is only 1cm*1cm in size at most, it is much more convenient than using a brush!
Shen Le was greatly encouraged. He used a cleansing spell, then another cleansing spell, and then another cleansing spell.

The faster he threw, the larger the area he covered. Later on, he could even do without the help of a microscope. The scope and sophistication of this cleaning technique depended on his ability to observe.
And his observation ability, using his mental power to penetrate deeper, can surpass that of a microscope, at least, surpass that of a microscope with a lower magnification!
Very good!

Work!

"What is he doing?"

"He doesn't even use his tools, he's just sitting there in a daze?"

"Wait, you see, he's not in a daze—that pile of coins! That pile of coins has become clean!"

“I didn’t see that…”

"If you can't see it, look next to it! On the white paper where the dirt was placed! There are more and more things! It's obvious that the dirt was moved here!
——Hey, can we ask him later how he did it? If possible, we can do the same next time..."

After finishing a morning's work, the researchers who were about to go to eat stopped one after another. The old professor was still quite reserved, only muttering in his stomach, but not speaking out;

Young researchers and students couldn't help but whisper to each other. There is a good way, who wants to suffer!
Who wants to sit in front of a microscope for two or four hours at a time? You don’t have to wait until you are old and cervical spondylosis will occur. In just two or three years, a physical examination will tell you the truth:

The physiological curvature of the cervical spine becomes straight, the physiological curvature of the cervical spine becomes arched, and the cervical ligaments become calcified...

Even if you hide your illness and avoid seeing a doctor or going for a physical check-up, you will still feel stiff shoulders and neck and dizziness.

After work, if you don’t go to a massage parlor, you should find a massage chair and spend 15 minutes massaging it…

"Don't even think about it. This is a special ability." Because they touched something that was sealed by the Special Affairs Bureau, the guy who came to hand it over stood on tiptoe to take a look and immediately struck them mercilessly:

"The principle is very simple, it's just using mental power to move objects. Many people in the Special Affairs Bureau can do it. However, to be so precise and able to work under a microscope, there may not be one person in a thousand!"

"what……"

"Ugh……"

"Why attack us..."

The students retreated wailing. Shen Le enjoyed it, and it only took him half an hour to clean up the pile of metal pieces.
Except for the edges he deliberately left, the areas cleaned with the cleaning technique, and the areas cleaned manually, the naked eye could no longer see any difference.

Then put the metal piece under the microscope, observe it carefully, and send it for a CT scan. It’s very good, there is no mechanical damage inside, perfect!

Using magic to do things can even train your mental power to a fine level!

Shen Le was full of energy. He wolfed down his lunch and began to think about rust removal.

Well… In theory, for this kind of rust removal on fragile metals, you can choose solvent rust removal, mechanical rust removal, or reduction rust removal;
However, considering that the purpose of his rust removal is to separate the parts that are stuck together...

"How about I tinker with the metal element to see if I can remove the rust?"

Just do it. When Shen Le was dismantling the big black fish in the seabed, he was already quite skilled in extracting the gold element.
When reinforcing the iron nails and various iron parts in Yun Kun's body, he had tried injecting the metal element into the iron parts countless times.

At this moment, sitting in front of the metal piece, his mental power naturally probed into it:
"Here is the coin itself... Here is the rust... Lock onto a piece of rust, extract its power, and get started!"

The invisible and intangible spiritual power locked onto a small piece of copper rust. With just a turn, the rust instantly disappeared, replaced by a small silver-white light spot that could only be seen in meditation:

"Very good. Go where you are supposed to be!"

The silver-white light sank and sank into the coin. Shen Le was delighted to find that the texture of the coin had become a little harder and a little thicker.
It's starting to return to its original state!
efficient!

Shen Le repeated the action of "draining the rust - returning the coins" several times. Suddenly, a soft "ding-dong" sound rang on the table in front of him:
The copper piece, which had been cleaned of rust and completely injected into the main body, thus separated from the pile of coins, jumped high and spun rapidly on the table...

"Wait, this method of repair seems to give too much spirituality! It's alive!"
