The old things I repaired have become fine

Chapter 31 Pinocchio can help! So good!
"Alas, rust is still easier to deal with." Shen Le sighed as he used a dilute baking soda solution to neutralize the residual acid on the surface of the shaft:
"Especially for things like this that are not very old and have no cultural relic protection value, just throw them in the rust removal liquid, take them out to neutralize the acid, wash them clean, and they are basically fine. The rust on bronze artifacts is very difficult to remove, and rust removal is simply not a job for humans..."

"How did you remove the rust?" Xiao Ling leaned over again:

"Use this rust removal fluid?"

"That won't work. It's for removing rust from iron. Bronze is made of a different material and is extra fragile, so it needs a different formula. Can you guess what it's made of?"

"How can I guess that?" The puppet jumped onto his shoulders, grabbed a strand of his hair and shook him back and forth:

"Speak! Speak!"

"In the early days... that formula was very troublesome..." Shen Le felt lonely working alone, so he told Pinocchio a story to cheer himself up:
"Remove the seeds from 500 grams of red fruit, add 250 grams of rice vinegar, 250 grams of glacial acetic acid, 100 grams of salt, 100 grams of ammonium chloride, and 100 grams of copper sulfate. Then cook in a casserole..."

"Casserole?!"

"Yes, you have to use a clay pot, cook the red fruit until it is pureed, then add a little fuchsia and mix well, then apply it to the copperware!"

"This will work?"

"It works, and it's quite useful." Shen Le laughed:
"The senior master of cultural relic restoration also praised this formula, saying 'Although it takes a long time, it is gentle and will not damage bronze objects...'"

This is all due to the lack of resources and low technical level in the early stage. You can use industrial formulas, such as formic acid, cysteine, triethanolamine and borax, but who wants to cook red fruit puree in a laboratory?
After neutralizing the residual acid, remove it, wash it with clean water, and wipe it dry. The rust remover that Shen Le ordered was also customized by their school. It contains corrosion inhibitors, which have a certain protective effect on ironware. Wash and dry it, dry it thoroughly, and apply a layer of anti-rust paint. Then insert the wooden handle back into the ink fountain:
"Perfect!"

The handle turned smoothly without any sluggishness or jamming. While he was adjusting the handle, Xiao Ling jumped up, put the reel on her knees, and began to wind the thread with one hand and the reel in the other.

She was agile and her little hands almost left an afterimage as she held the thread end. She wound the thread a few points faster than Shen Le.

Shen Le had finished debugging, and she had handed the reel back. She watched Shen Le fix the reel and handed the thread end to her:
"Xiao Ling, please help me thread the thread through the ink tank... Hey, great!"

After a word of praise, Xiao Ling jumped up high, grabbed the silk thread, and jumped under the table. She was like a large plumb bob, hanging the ink line, and dropped it out, landing under the workbench in one breath. Swinging, swinging, swinging, like a swing, she was extremely happy.

Shen Le: “…”

He quickly put two large pieces of cotton wool in the ink tank and poured in ink. He placed the ink fountain flat on the table and pulled it back until the ink line was almost flat on the table. He twisted the ink line, pulled it up, and released it.

"Zheng!"

With the sound of a string, a straight, ink-black line appeared on the tablecloth of the workbench.

"Great! If it weren't for the need to repair the exterior, this would actually be very useful..."

As he muttered to himself, his vision changed again. Shen Le was no longer surprised, but rather happy. Well, my vision is very accurate!

This little inkstone can indeed develop intelligence, and it can indeed contribute a large amount of experience points to his copper pieces!

Look, we have just finished the beginning, and it brings new fragments of memory!
He stood up straight and looked around.

The room was only about 7 or 8 square meters in size, with a low ceiling that made it difficult to stand upright. A musty smell wafted in from the old wooden walls. On the mottled square table, the flame of a kerosene lamp flickered gently.

Under the dim light, the young man's strong, powerful, yet calloused hands held a carving knife, cutting and digging carefully.

"Oh no! It's broken again! - Master, this devil's ball is too difficult to make. It's impossible to make it in such a small space!"

"Impossible? That's because you don't know how to do it." A pair of hands with loose and wrinkled skin and many age spots took over the wooden beads and the carving knife, and swished and swished, swished and swished, and swished gently. The old man's strength was not as good as that of the young man, but his hand holding the knife was extremely stable. Every time he pushed out and shaved, the wood chips shaved off were exactly the same in size and shape. While shaving, he explained to his apprentice:

"You need to keep your mind calm and your hands steady. Follow the grain of the wood and vary the strength of your hands slightly. Don't just use brute force. Look, here..."

"Master, you are a level 8 worker, and I am only a level 8 worker... Just because you can do this thing easily doesn't mean I can do it too!"

"If you can't do it, practice more!"

After the old man finished carving a circle, he handed the wooden bead and carving knife back to his apprentice and watched him work on it slowly. After watching for a while, he couldn't help laughing and said:

"Aijun, when will you finish making this devilish ball? Do you need your master to help you? There are many young men chasing after Chang Hong~~~"

"Master!"

The young man yelled in a bit of embarrassment, his ears turned red. Even so, he refused to give up:

"I agreed to do it myself, so I have to do it myself! If you do it for me, Chang Hong will look down on me!"

The old man laughed loudly for a while, then stood up and walked out of the room. He put his hand on the door, paused, and turned around and said:
"Aijun, the more you think about it, the less anxious you should be. If you carve beads while thinking about Chang Hong, you will probably get nothing in the end!"

The old man walked away, leaving behind the young man named "Aijun" to carve the ghost ball one stroke at a time.

Shen Le stood beside him, craning his neck to watch carefully each of his knife movements and the details of his every exertion of force:

The more I looked at it, the more I felt sad. The more I looked at it, the more I felt that there seemed to be no hope for me to repair this ghost ball.

The old man was an eighth-level worker, and his apprentice, who was kneading the ghost ball, was probably a third or fourth-level worker. And how many levels could I be?

Second level worker?
First-class worker?

It can’t be that it can’t even be rated as level one?
But, as the old man said, the better the dish, the more practice it will take.

Shen Le lay beside the young man named "Aijun", watching while moving his fingers gently, as if he also had a wooden ball in his hand, pinching the ball in one hand and the knife in the other, up and down, up and down.

I don't know how long I watched and imitated, but the light and shadow in front of me suddenly began to change.

Shen Le looked up blankly, looking left and right, and found that he had changed his environment, from a cramped house to a spacious factory building. Ouch?
The memory transmitted by this copper piece has a new function. Can it provide two memories at a time?
