"On this day last year, in this door, the faces of the people and the peach blossoms reflected each other's red.——"
The singing on the stage was melodious and clear, and cheers came from the audience from time to time.
Although Jian Yue Troupe still performs a tortuous love story between a wealthy daughter and a scholar, it is indeed professional enough.
In order to express landscapes and gardens, hollow rockeries made of plaster and painted with paint are placed on slide rails and pushed to the stage.
In order to show the arrival of immortals to save the lovers in distress, slings painted black and integrated with the stage are used, as well as protective gear tied to the actors and connected to the slings.
Talismans can also be used to create smoke, rain, fire effects, etc.
The audience sitting in front can even directly feel the water vapor on the stage.
It feels like a 4D movie.
A normal play lasts for two hours, with three pauses in between to allow the audience and actors to rest. When the scholar on the stage finally passed the exam and got married to the wealthy daughter with the blessings of the emperor and immortals, and the union was complete,
There was warm applause from the audience, and people kept throwing flowers and money on the stage.
The actors collectively came on stage to express their gratitude, the curtain slowly fell, and the play officially ended. The waiters from the Jian Yue Theater Company opened the curtains of the theater to let in the evening light. The audience left their seats one after another, still discussing the plot in low voices when they left the theater.
"how do you feel?"
Li Ang saw the excited expression on Chai Cuiqiao's face and asked casually.
Chai Cuiqiao thought for a while and nodded seriously, "Yeah... It's quite exciting. But the rich girl returned to the sun after her death, and when she met the scholar again, she was still wearing the same skirt - hers Didn’t the body stay in the grave for two years? Wouldn’t it be infested with maggots or something like that?”
"Uh, maybe it was because preservatives were applied after death? Or when the Bodhisattva allowed her to return to the sun, her body was also repaired. Of course, it's more likely that the stage effect is not easy to restore."
It’s not like the children’s biology class in Memory of Another World, where silkworms and maggots can be interchanged.
Li Ang and Chai Cuiqiao walked out of the theater chatting, and suddenly stopped in their tracks.
Chai Cuiqiao asked curiously: "What's wrong?"
"No, it's nothing."
Li Ang frowned slightly and glanced back at the theater stage behind the gate. Not sure if it was an illusion, but when he walked out of the gate, he felt a faint chill down his spine.
Maybe it's the cool breeze charm inside the theater.
Li Ang waved his hand and took the carriage back home with Chai Cuiqiao.
"Grandma, why are you here?"
The boy in the troupe who was cleaning the stage was surprised to see the old woman in gray who appeared behind the thick curtain at some point, holding a broom and dustpan, and peering through the cracks in the curtain at the audience leaving the venue.
"Hey, didn't I ask you to stay backstage? Why did you come to the stage? Fortunately, you didn't go out during the performance, otherwise it would have been a performance accident."
The boy from the troupe chattered, took the broom and dustpan from the old woman in gray, and helped her off the stage, "Let's go quickly. Don't let the troupe leader see it, or he will scold her again..."
The old woman in gray clothes followed the troupe boy gently and quietly to the backstage.
A pair of skinny palms trembled slightly, and several tiny cracks appeared inexplicably on the back of the hands, hidden under the layers of wrinkles on the skin, like porcelain about to break.

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, absorbent cotton balls, and absorbent cotton cloth.
As a doctor of science from the Academy, Su Feng naturally knew that Li Ang invented midwifery forceps and assisted the Ministry of Household Affairs and the Ministry of Works in formulating anti-malaria strategies.
He was an inventor himself. After seeing the large stack of drawings and finished products that Li Ang brought, he was a little surprised and accepted it.
First, I checked some past information and confirmed that there were no highly repeated inventions of the same type, and then 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 wrong? Are you in a hurry for 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 best at running camps and has a mansion and a beautiful concubine in Chang'an, may not be richer than him.
"This depends on the profit prospects of the patent and whether there are any companies willing to buy or lease it."
Su Feng said: "Generally, it takes half a year to get the money, and it can take several years. But your soap, as well as absorbent cotton, are used a lot in daily life. The prospects are very good, and you don't have to worry about not being able to sell them.
I will work with the teaching doctor from the Academy of Science and Technology to conduct experiments based on your drawings. If we can produce a product, we will publish the information in the Academy of Science and Technology Journal - those big businesses will also subscribe to the Science and Technology Journal.
When they see a new invention, someone in charge will come to the academy to inquire about a quote. "
"Thank you very much, Dr. Su."
Li Ang breathed a sigh of relief. The academy has always been rigorous and careful. Some interesting patented inventions need to be verified experimentally before being published in publications.
You won’t be surprised just by looking at the process drawings of soap and other soaps - after all, there are already cleaning products like "Yizi" with the same complicated production process.
Whether a patent can be sold ultimately depends on factors such as product performance, cost, production threshold, and profit prospects.
However, judging from Chai Cuiqiao's high praise for soap, soap, and absorbent cotton cloth, there is no need to worry about the lack of market for these items.
Li Ang asked Su Feng to help him hide the name of the inventor of absorbent cotton cloth from newspapers and magazines, and then went back to continue class.
The mobility of Su Feng and others was far beyond his imagination. By evening, Su Feng and other academy teachers used the abundant material reserves from the patents and the monks' abilities to reproduce the product line of soap, toilet soap, and absorbent cotton. ,
Dozens of samples were produced.
And Su Feng also understood why Li Ang asked about the patent sale time-compared to the previous "pancake", soap soap is simply crushed in all aspects.
The smell of pig pancreas is good, but the color is grey-brown and ugly, round and sticky. It looks a bit disgusting after being used for a long time.
Soap soap not only smells good, is plain in color, and is rectangular in shape. It also foams when used, and its cleaning ability is as good as or even better than that of a soap.
Not to mention absorbent cotton, it is white in color and does not turn yellow, soft to the touch, and has excellent water absorption properties. It can be made into clothing or quilts without any problem.
More importantly, Li Ang also specifically marked the dangers that may arise in all production links on the drawings.
And any company that wants to produce these products must provide workers and temporary workers with protective equipment such as gloves and masks, otherwise the patent will be forcibly withdrawn.
"Not only did he invent the product, but he also considered in advance that some companies would do whatever it takes to make a profit."
"You are very careful and considerate at such a young age. You will be formidable later in life."
"What's rare is that you still have a kind heart. As expected of a doctor. By the way, I'll take these soaps home first and help you guys try them out in advance."
"Shameless! This is the property of the academy, how can you take it home? Whoever produces the raw materials will belong to whom. I brought the cotton cloth for these absorbent cotton, so it belongs to me first——"
Li Ang didn't know the chatter of the professors in the patent office. After a busy day of study, he returned to his home in Jinchengfang, washed up and fell asleep tiredly.
When he opened his eyes again, what he saw was not the familiar bedroom roof, but a blood-red sky.
