Ask Sword

Last year and today, in this gate, people's faces are red with peach blossoms.—

The singing on the stage was melodious and clear, and applause came from the audience from time to time.

Although the Jianyue Troupe is still performing the tortuous love story between a wealthy daughter and a scholar, it is indeed professional enough.

In order to express the landscape garden, the hollow rockery made of plaster and painted with paint will be placed on the slide rails and pushed to the stage.

In order to show that the immortal came to save the couple in distress, a sling painted black and integrated with the stage was used, as well as protective gear tied to the actor's body and connected to the sling.

Talismans will also be used to create smoke, rain, flame effects, and more.

The audience sitting in front can even directly feel the water vapor on the stage.

It feels like a 4D movie.

A normal repertoire lasts two hours, with three pauses in the middle to allow the audience and actors to rest. When the scholar on the stage finally won the first prize in the exam, and with the blessing of the emperor and the gods, he tied the knot with the daughter of a rich family, and when the unity was complete,

There was warm applause from the auditorium, and people kept throwing flowers and money on the stage.

The actors came to the stage collectively to express their thanks, the curtain fell slowly, and the play officially ended. The young men of the Jianyue Troupe opened the curtains of the theater to let the evening sun shine in. The audience left their seats one after another, discussing the plot in low voices when they left the theater.

how do you feel?

Seeing the excited expression on Chai Cuiqiao's face, Li Ang asked casually.

Chai Cuiqiao thought for a while, then nodded seriously, Yes, it's very exciting. But when the rich daughter returned to the sun after her death, when she met the scholar again, she was still wearing the original dress—wasn't her body in the Two years in the grave? Don't they grow maggots or something?

Uh, it might be that preservatives were applied after her death? Or when the Bodhisattva let her restore her yang, she also repaired her body. Of course, it's more likely that the stage effect was not restored.

It's not the children's biology class in the memory of the foreign world, where silkworm babies and maggots can be exchanged.

Li Ang and Chai Cuiqiao walked out of the theater chatting and suddenly stopped.

Chai Cuiqiao asked curiously, What's wrong?

No, nothing.

Li Ang frowned slightly and glanced back at the theater stage behind the gate. He didn't know if it was an illusion. The moment he walked out of the gate, he felt a faint chill down his spine.

Maybe it's the Cool Breeze Talisman in the theater.

Li Ang waved his hand, and he and Chai Cuiqiao boarded the carriage and returned home.

Grandma, why are you here?

The troupe boy who was cleaning the stage looked in surprise at the gray-clothed old woman who appeared behind the thick curtain at some time, holding a broom and dustpan, and spying on the audience leaving through the gap in the curtain.

Hey, didn't you let you stay in the background? Why did you come to the stage? Fortunately, you didn't go out during the performance just now, or it was a performance accident.

The troupe boy chattered, took the broom and dustpan from the old woman in gray clothes, and helped her off the stage, Let's go quickly. Don't let the troupe leader see, or he will scold you again.

The old woman in gray followed the troupe boy to the backstage gently and quietly,

A pair of thin palms trembled slightly, and the back of the hands was inexplicably cracked with a few tiny cracks, hidden under the layers of wrinkles of the skin, like porcelain about to shatter.

The short two-day vacation passed quickly. After Li Ang returned to the academy, he went to the patent office to find Dr. Su Feng to register the patents for soap, cotton balls, and absorbent cotton cloth.

Su Feng, as a doctor of science, naturally knew that Li Ang invented forceps and assisted the Ministry of Households and Industry to formulate malaria prevention strategies.

He is an inventor himself, and after seeing a large stack of drawings and finished products that Li Ang brought, he was slightly surprised and accepted it.

I went to check the previous information first, and after confirming that there were no similar inventions with a high degree of repetition, I quickly completed the patent registration process.

Dr. Su,

Li Ang accepted the patent certificate and asked, How long will it take to sell this patent?

Su Feng asked with a smile: What's the matter? Are you in a hurry to spend money?

Um.

Li Ang nodded. As far as he knew, Su Feng, who had many invention patents, was a hidden rich man himself. Even Xi Yangyu, who is the best at making money and has a beautiful concubine in a mansion in Chang'an, may not be richer than him.

This depends on the profit prospects of the patent, and whether there are companies willing to buy or lease it.

Su Feng said: Generally, it takes half a year to get the money, and it takes several years. But your soap, as well as absorbent cotton, are widely used in daily life. The prospect is very good, and you don't have to worry about not being able to sell it.

I will conduct an experiment with the teaching doctor of Xuegong Publication Office according to your drawings, and if the product can be produced, the information will be published in the Xuegong Journal of Science—those big companies will also subscribe to the journal of Science of Science,

When seeing a new invention, someone in charge will come to the academy to ask for a quotation.

Then thank you, Dr. Su.

Li Ang breathed a sigh of relief. The Academy has always been rigorous and careful. Some interesting patented inventions will only be published in publications after experimental verification.

You won’t be shocked just by looking at the technical drawings of soap and soap—after all, there are already cleaning products like “pancreas” that are also cumbersome and complicated.

Whether the patent can be sold or not depends on factors such as product performance, cost, production threshold, and profit prospects.

However, judging from Chai Cuiqiao's satisfaction with soap, soap, and absorbent cotton cloth, there is no need to worry that there will be no market for these items.

Li Ang asked Su Feng to help him hide the name of the inventor of the absorbent cotton cloth from the newspapers, and went back to class.

And the actions of Su Feng and others were far beyond his imagination. In the evening, Su Feng and other school teachers used the material reserves rich in patents and the ability of monks to reproduce the product line of soap, soap, and absorbent cotton ,

Dozens of samples were produced.

And Su Feng also understands why Li Ang asked about the patent sale time - soap and soap are simply crushed in all directions compared to the previous pancreas.

The smell of pig pancreas is good, but the color is gray-brown and ugly. It is round and sticky after being used for a long time. It looks a little disgusting.

Soap Soap not only smells good, is plain in color, and is in the shape of a cuboid. It also produces foam when used, and its cleaning ability is not inferior or even surpasses that of soap.

Not to mention the absorbent cotton, which is white in color without yellowing, soft to the touch, and has excellent water absorption performance. Even if it is used to make clothes and quilts, it is no problem at all.

What's more, Li Ang also deliberately marked all possible dangers in the production process on the drawings,

And any business that wants to produce these types of products must distribute gloves, masks and other protective equipment to laborers and temporary workers, otherwise the patent will be forcibly withdrawn.

Not only invented the product, but also considered in advance that some companies will do whatever it takes to make a profit.

Be careful and considerate at a young age. Young people are formidable.

It's rare to have a benevolent heart. As expected of a medical background. By the way, I'll take these pieces of soap home first, and try it out for everyone in advance.

Shameless! This is the property of the academy, how can you take it home? Whoever produces the raw materials will belong to them. I brought the cotton cloth used for these absorbent cotton, so it belongs to me first—

Li Ang didn't know the chatter of the instructors in the patent office. After a busy day of study, he returned to Jinchengfang's home, washed up and fell asleep tired.

When he opened his eyes again, what he saw was not the familiar roof of the bedroom, but a blood-red sky.
