The old things I repaired have become fine

Chapter 265: The second episode of "Focusing on Friends and Family"! And you still say you don't like this girl!
The glue alum cooked silk is treated by hydrolysis and light aging methods.

The raw silk is treated by heating and then brushed with glue and alum water to make finished silk.

Various methods of observation, various methods of testing...

In this kind of experiment, 48 hours will pass to process one sample.

This is still good. According to the paper "Research on Artificial Aging and Reinforcement of Silk Paintings Colored with Mineral Pigments", before the samples are processed, they must be placed for 350 days for artificial aging...

This is a master's thesis, and the study period for a master's student is only three years.

In other words, if he had not decided on the research topic and steps for his master's thesis from the day he entered school, he would have had to use some of the results of his seniors.

Oh, of course, there is another way to go, which is to delay graduation. But...

Mr. Yamagami, you don’t want to delay your graduation, right?

Fortunately, Shen Le didn't need to go through these 350 days. He didn't have particularly strict requirements for the accuracy of the experiment, so he simply skipped the natural aging step.

Brush glue and alum water directly on the raw silk, set up the scale, set up the measuring cup, weigh, heat, dissolve... Teacher Zhang shook his head as he watched:
"If everyone works like you, we who are engaged in calligraphy and painting restoration can't do much in a day. Taste it and remember the taste. It's slightly bitter and astringent. This concentration is right!"

Shen Le looked at Teacher Zhang warily for a long time before, at the teacher's urging, he dipped a little bit of alum water and tasted it.

Really, why do you have to taste it yourself when you can just write down the proportions! Even if you don’t taste it yourself, with the scale and measuring cup, he won’t fail!

Eating too much alum will affect intelligence - well, talking about toxicity without considering the dosage is just a hooligan...

Apply glue and alum water, let it dry, test, and compare. After several days of tossing and turning, finally, Teacher Zhang chose the previous version:
Use 2% gelatin and 0.5% alum to prepare gelatin-alum cooked silk, place it in an oven at 150°C and continue aging for 24 hours...

Well, it's like revising the manuscript for the client seven or eight times, and then the client says, "Let's just use the first version." That kind of beauty that only belongs to office workers...

Shen Le swallowed his anger and began to prepare artificially aged silk in batches.

Thankfully, after artificial aging, the silk does not need to be dyed again and is similar in color to the center of the painting.

Cut out pieces of silk in the same shape as the hole in the center of the painting. Then, piece the pieces of silk onto the hole in the painting silk, with the warp threads aligned and the weft threads aligned, neatly aligned and without any error.

After reaching this step, Teacher Zhang became envious and jealous, and he almost wanted to snatch Shen Le away from the research group:
Using the abilities of a practitioner, he made the silk threads of the patched silk and the painting center grow together one by one, seamlessly...

"It's unreasonable to use your ability to repair fabrics...

Alas, it is not useful for cultural relic restoration, but helping the rich to repair family trees, ancestral portraits, etc., that is simply a core competitiveness, countless gold and silver mountains..."

Teacher Zhang kept mumbling to himself. Seeing Shen Le's speechless gaze, he smiled to himself:
"Well, since you are already financially independent, you don't need a lot of money..."

"...Actually, this ability isn't that strong." Shen Le slowly replied, deciding to give the teacher a little shock in the cultivation world:

"Last time when I was repairing that wedding dress, I was worried about how to mend the hole. A friend asked me if I could introduce a silkworm demon to help me mend it. Yes, it's a silkworm demon that spins silk..."

Teacher Zhang covered his face and retreated.

For a job like mending a hole, there is really no need for Teacher Zhang to stay by and watch over it all the time.

He went to the laboratory and watched the students doing experiments, watching them not to be careless and blow up Shen Le's laboratory. Shen Le himself slowly connected the silk threads one by one.

I had repaired the whole painting before, so repairing a small hole like this was as easy as a vacation. It only took one day to complete the entire painting.

Then use 1.5% silk fibroin solution and 4.5% EGDE (ethylene glycol diglycidyl ether) solution, spraying alternately every 15 minutes until the center of the painting is soaked.

After drying, the color of the painting core remains unchanged, the ink absorption and ink support feel remains unchanged, but the fragility of the painting core increases slightly...

More importantly, after this spraying and reinforcement, Shen Le clearly saw that the spirituality in the painting flickered and inhaled and exhaled.

The original spirituality of the painting slowly "flows" along the silk threads connecting the silk patching to the newly added silk patching.

After flowing evenly, he breathed in the power that permeated the surroundings and slowly rose...

"Do you like this approach?"

"Is this method of repair good for you?"

Shen Le asked it with a smile. In the cabinets around it, the cut tops, bottoms, edges, peeled backing paper, as well as the shafts and the gold foil inside the shafts, flickered at the same time:
They emit a brilliance that is invisible to the naked eye and can only be observed by the spiritual eye, and are connected to the heart of the painting.

And this light became brighter and brighter, more and more active, and finally, it merged into one and covered Shen Le head-on.

It turned into a man and a woman standing and sitting in the military tent, facing each other silently, and the young alloy boss growling in displeasure:
"Ow—"

You value women over friends!
You value women over friendship!!!

"Xiao Jin, don't be angry." The young man was covered in blood, holding a long knife in one hand and stuffing the golden hairpin into the girl's hand with the other hand. He quickly turned around to comfort his friend:
"I promised you that you can eat whatever you want, but what I promised you are the things of the owner of this military tent, not the girl's things!

——Even if you want to eat it, don’t bite it directly from her hair, what if you scare her? "

"Ow—"

Xiao Jin continued to roar angrily. His transverse bone had not yet been dissolved, so he could not speak for the time being. He was so angry that he did not want to write on the ground to refute, so he just roared. Aren't the things of the owner of this military tent everything in this military tent?

Women, women in the Tartar army's tent, all belong to the owner of the tent! The jewelry in her hair is also his! His! His food!

Shen Le was watching from the side, feeling both angry and amused. The Alloy Boss was still in his infancy, and didn't understand that some things belong to you only after you put them in your mouth.

You have free time to yell and argue with your friends, why don’t you seize the time and eat as much as you can!
When the young man's comrades come in, they will collect the spoils. These golden bowls, golden plates, golden pots, and golden candlesticks will no longer belong to you!

And this young man, you are afraid that Xiao Jin will scare the girl, but why aren’t you afraid that you will scare the girl yourself?

Compared to the strange beast that only eats jewelry and not flesh and blood, your armor, sword, face and hands are all covered in blood, even your gold hairpin is stained with blood. You are more likely to scare her, okay!

However, the girl on the couch was obviously not so easily frightened.

She slowly sat up and brushed her scattered hair. Seeing that she couldn't put her hair up after removing the golden hairpin, she simply took out her short knife, cut a piece of animal skin, and tied her hair up behind her head:

"Since the general has promised you the exotic beast, he should fulfill his promise. I am grateful to the general for saving my life. Please take this golden hairpin back."

Xiao Jin let out a low growl, his voice now much softer, and jumped onto the table next to him, attacking a golden plate.

The young man was stunned for a moment, and instead of taking back the hairpin, he took a step back:
"Girl, are you Han Chinese? Were you kidnapped by him? Where is your home? Do you want me to take you home?"

The girl smiled slightly. She jumped off the couch, adjusted her skirt, and bowed:

"I am not a Han Chinese. However, I am not from the Toluo Khan tribe that attacked this time. I am from the Oirat tribe. I came here to visit my grandfather, but was forced to stay by Toluo Khan.

——Kind General, could you please help me take a letter to my father to take me home? "

Oirat...

Shen Le thought about it for three times, but couldn't remember which tribe this girl was from. The young man was already in embarrassment:

"The Oirat tribe is far to the west, and although they have submitted and paid tribute, they have little contact with us.

If I can prove your identity, it won't be difficult to save your life, but if I want to help you deliver the message, I have to wait for the opportunity to see when the caravan arrives - can you afford to wait?"

You have to wait even if you can't afford to. Fortunately, the boy's father still attaches great importance to this Tatar noblewoman, or the tribe behind the Tatar noblewoman;
Not only did they attach importance to him, but after he submitted the letter to the court, the court also had the intention of making friends with distant countries and attacking nearby ones, and instructed him to treat him well, find a chance to return the girl, and make friends with the Oirats.

With these words, the girl stayed in the city, waiting for the caravan to deliver the message.

The grassland is vast and there are defeated soldiers. I don’t know when we can reach them. Even if we do, it will be impossible to cross the grassland when the white wind blows in winter.

The girl's return date is estimated to be next year...

The girl herself was not in a hurry. She lived quietly in the house assigned by her father, took out her golden hairpin and exchanged it for a flock of sheep. She went out to herd sheep every day, milked them, and made milk skins and milk chews.

Sometimes the boy would go out to see her, and seeing how unbecoming she was, he would try to persuade her, but the girl would just smile and shake her head:

"I have to do these things at home, too! Besides, I don't know when my father will come to pick me up, or whether he can come to pick me up. It's always right for me to support myself!"

"But girl, you are making it very difficult for us to do this. It seems that we don't know how to entertain guests." The young man hesitated for a long time and had to persuade her:
"You are our guest. If we can't even guarantee you food and clothing, we, as the host, will be too shameless. Even if the court knew, they would hold you accountable!"

"Is that so?"

The girl put down her shepherd's whip and said solemnly:

"...But I can't always be a useless person and rely on you to support me..."

"Then can you tell me something about your life?" The young man said:

"Tell me some things about your tribe. Where is your tribe? How far is it? How many mountains and rivers do you have to cross? How do you herd sheep, how do you drive horses, how do you hunt..."

The girl bowed her head and said nothing. She was not an ordinary shepherdess, she knew that if she told these things to others, at some point, they might become a sharp blade that would stab her.

The young man noticed her expression, thought quickly, and suddenly blurted out:
"In exchange, I'll teach you to read!"

"Ouch, ouch, ouch—"

The Alloy Boss shouted again nearby.

And you said you don’t value love over friendship!

I asked you to teach me how to read, but you always made excuses!

　In order to find out the preparation method of alum water, Cat checked three papers, and then checked again and again. Something is wrong. Why do I feel like I have seen this paragraph before?

　　Looking back again, I found that this paragraph is repeated in all three MD papers!

　　Just taking out this paragraph, the duplication rate is not 100%, but at least 90%!
　　Why did I work so hard to look up information? So that you can copy each other?
