The old things I repaired have become fine

Chapter 217: Shen Le, is there a bloody incident in your family? Or is there a murder?

"Finally I solved a difficult problem..."

Shen Le sighed. There are many ways to repair fabrics. He looked up papers, read materials, and looked at pictures of repairs done by experts. He felt that he couldn't do it.
After being repaired by an expert, the damaged area can be made to have almost no signs of repair when viewed from a distance, and only tiny stitches can be seen when viewed up close.

Shen Le sewed it himself by following the same pattern. After sewing, the stitches on the front were very obvious, and the loose silk threads at the damaged part were either sticking up high on the surface or curled up into a ball.

In short, even with the help of the copper sheet and the control and concentration brought by the inner strength, Shen Le felt that he would not be able to do it without seven or eight years or ten years of practice...

Now it's much better. Use your mental power to pull the silk thread, let the silk protein solution adhere to it, extend naturally, and condense into new warp and weft.

The damage he repaired was so seamless that no one could tell. Shen Le was very satisfied and gave himself a thumbs up:
"Is this the silk protein reinforcement method? How about it? Are you satisfied with my repair?"

In the safe, the red wedding dress fluttered twice, the outer robe stood up halfway, and pushed the door open with all her strength. Shen Le rushed over and pushed it down:

"Hey, just lie still! If you have anything on your mind, just speak up! I can't hear you, but you can ask Lan Zhuang to tell you!

——The silk on your body has become brittle and hard, and can’t stand your torture!!!”

The red wedding dress dodged left and right, twisted a few times, and finally lay down quietly. The dressing box beside her spoke for her:

[It wants to see the part you repaired...]

Of course you can look at it. Shen Le held the curtain in front of the safe, showed it up and down, left and right, and even shone a strong flashlight on it;
Then, enduring the fatigue caused by the massive depletion of mental strength, he displayed the red wedding dress once again.

Hong Jiayi was slightly satisfied, but still had some doubts:

[It said, this method is good for filling the gap, but it can't be used for embroidery! ]

Shen Le's brain was buzzing. Yes, this method cannot be used for embroidery. You reminded me very well. Can you not remind me next time?
It is impossible to expect the silk fibroin solution to "grow" on those loose, falling off, and disappearing embroidery.

To embroider it stitch by stitch, you have to use other methods...

[It said, if it can’t be embroidered well, it doesn’t matter.] Lan Zhuang continued to relay Hong Jiayi’s thoughts. It might be comforting, but to Shen Le, it sounded more like finishing off the attack:

[Anyway, its owner is not very good at embroidery, so he doesn't really care how the embroidery is done. If it can be mended, then mend it. If it can't be mended, then forget it! ]

That won't work!

In the hands of cultural relics restorers, there is "try to keep it as original as possible", "repair the old as it was", and "the restoration process must be reversible".

However, unless the craftsmanship is extremely poor, the repair process will cause damage to the cultural relics. There is never a saying of "repair it if it can be repaired, and forget it if it cannot be repaired"!
Shen Le wanted to continue trying to find a way to use this talisman for embroidery, but his mental strength was exhausted and he couldn't continue.

He reluctantly took a break, returned the curtain to its original place, and began to repair the red wedding dress. Well, of course, the first step of the repair was to remove the stains:

He had promised the red wedding dress that he would make some progress in repairing it every day and would never abandon it unless it was absolutely necessary.

Now that the horse-faced skirt and the red outer robe have been cleaned, it's time for the brocade jacket...

Shen Le spread three layers of brand new, de-starched white cotton cloth on the workbench, then placed the brocade jacket on the workbench and unfolded it carefully.

Front, collar, cuffs, front placket, buttons; unfold the placket and observe the lining...

Shen Le's eyes suddenly froze. When he first unfolded and kept the clothes, he only roughly observed whether the clothes were damaged or had any obvious stains;
However, this time, in order to remove the contamination, he conducted a careful investigation and discovered new circumstances.

On the lining of the brocade jacket, this bright red silk lining that has become dull with the passage of time, there are pieces, clumps, and drops of this stuff. What is this?
If he was not mistaken, these traces looked like blood!

Shen Le's first reaction was to reach for his cell phone and call Gu Yulin, or call Shi Guangbing, a police officer in his jurisdiction, to ask for some luminol reagent.

He reached for his phone, then suddenly stopped:

...By the way, is luminol reagent useful for bloodstains from hundreds of years ago?

He tried to search his memory to recall whether he had learned this knowledge point in school, but to no avail. Even if it was in the textbook, it probably wasn't emphasized, and even if it was, it probably wasn't highlighted.
I wanted to ask the instructor, but I didn't dare. If he had really learned this and forgot it, he would be scolded!
Shen Le had no choice but to look through the book, but couldn't find it. He searched for the paper on CNKI, changed a few keywords, but still couldn't find it.

He then asked Chapgpt, which he recently found to be more useful than Baidu, and was pleasantly surprised to get the answer:
In the documentary "More Than Archaeology: Me and Sanxingdui", researchers used luminol reagent to confirm that the red spots on the cultural relics were blood!
The Sanxingdui cultural relics are about 4800-2800 years old, which can be confirmed to be blood. The wedding dress in his hand is at most a few hundred years old, so it can definitely be used!
"Hello? Gu Yulin? - Can you help me get some luminol reagent?"

"What's wrong with you?!" Gu Yulin's voice on the phone suddenly became louder, sharp and urgent.

Without waiting for Shen Le to answer, he spewed out a lot of questions like a Gatling gun:

"Have you found any blood in the house? Has someone invaded? Is there a lot of blood? Is there anything unusual in the house now? - Don't move, I'll be there soon!"

"Wait a minute, I'm fine here!" Shen Le didn't know whether to laugh or cry. Hey, my house is invading, who am I afraid of?
With A-Lu sitting in the center of the mansion and Xiao Youdeng patrolling all the time, if there are any malicious intruders, these two alone can kill them instantly!

You should also be concerned about the intruder, how much weight is left, or whether he has turned into charcoal... "I just received an ancient wedding dress and found suspected bloodstains on it, so I wanted to verify it." Shen Le tried to make his voice as calm and slow as possible:
"Don't worry, that wedding dress is hundreds of years old, it's definitely not a modern thing."

"Really?"

"real!"

"Then the wedding dress is okay?"

"It's really no problem... Never mind, if you're really worried, just come and take a look!"

Gu Yulin rushed over half an hour later. Shen Le estimated that it would take him half an hour, and he probably went to a nearby branch to ask for some luminol reagent.

After entering the mansion, he looked left and right, holding the instrument in his hand, and swept along as if intentionally or unintentionally.

At least he showed some sincerity. In his other hand he held a set of reagent equipment and an ultraviolet lamp, indicating that he was here to help, not to investigate the case.

Shen Le pretended not to see it, led him into his studio, and pointed to the brocade jacket on the table:

"Here, look, it's this dress. The matching ones are all inside, take a look for yourself, it's best not to touch it - are you relieved now?"

Gu Yulin lay on the table and looked at it for a long time, then raised the instrument and measured several pieces of clothing.

Looking at the hundreds of marks beating non-stop, he felt his heart pounding. He wanted to say something but stopped, and finally, he sighed deeply:

"I won't advise you anymore. You are now an outside expert, a professional in this field. But you should still be careful..."

Shen Le nodded vigorously. Gu Yulin still refused to leave, and stayed behind with the excuse that he had never seen how to use the luminol reagent.

Shen Le secretly laughed, but did not expose him and started to make preparations on his own.

"Eh? Why don't you just grab a sprayer and start spraying?"

"Do you think I'm the forensic doctor on TV?" Shen Le rolled his eyes at him.

For a house where a murder happened, you can carry a big sprayer and spray it everywhere. When the ultraviolet light is turned on, there will be blue light everywhere. After taking pictures, you can just clean up the scene.
He is a cultural relic restorer! Cultural relic restorer! He sprays the reagent and then tries to clean it off?
Isn't this just asking for trouble?
Shen Le lay on the table and carefully prepared a little luminol reagent in a test tube. Then, he dipped a cotton swab in deionized water and soaked it in the suspected stains little by little...

"Are you doing a throat swab?"

"That's right." Shen Le smiled bitterly. He carefully soaked an area of one square centimeter of the stained area with cotton swabs, rubbing and rubbing, trying to wipe off some debris.

Then, wash the cotton swab repeatedly in a disposable plastic cup to produce some light brown water, and then use a dropper to drop luminol reagent into it...

"Not bright."

"So it's not blood?"

"It's hard to say. Maybe it's just too faint, or maybe it's been too long... Archaeology, anything is possible. Should we try a few more times?"

Shen Le took samples three or four times, tried three or four times, and failed three or four times. Finally, he became angry and poured the reagent on his clothes...

No, just carefully apply the reagent, absorb it with a cotton pad, and soak it in the suspected stained area.

After waiting for a while, turn off the light and turn on the ultraviolet light——

"It's so bright!"

It is definitely blood!

Gu Yulin heaved a sigh of relief, finally feeling relieved, and left with the UV lamp. Shen Le was left alone in the room, facing Jinao with a sad face:

"Hey, what happened in the first place? Why is it covered in blood?"

There was a long silence. Hong Jiayi did not answer, and Lanzhuang did not help to convey her message.

Shen Le was not disappointed. After all, if it was something important, it would naturally be presented to him during the restoration process.

The question he is struggling with now is:
"Hey, how do I clean this dress? Do I need to wash off this blood stain?"

"If this bloodstain is related to the owner's important experience and should be preserved, then how can we effectively clean other stains while preserving the bloodstain?"
