The whole family of villains criticized her wildly, but the princess treated her with medical treatm

"What is paper medicine?"

A look of confusion appeared on Yan Yangjun's face.

He didn't know much about papermaking, so listening to his fiancée talk about the steps of making paper was like listening to a book from heaven.

What kind of fiber, what kind of adhesive, what kind of bamboo curtain paper, my mind is so confused that I can't even come up with a specific picture.

"It's a kind of paper syrup. In papermaking terms, it refers to a certain plant-based adhesive glue material used in the process of making oak bark paper and paper mulberry bark. There are many types of plants that can be used, and they are not limited."

Mu Tingxue was like a teacher, patiently explaining to the students, "Papermaking is a very complex ancient technology, with a total of seventy-two procedures. One of them is to add paper medicine, which can make every piece of paper become Extremely delicate.”

Yan Yang dug into the details: "What kind of delicate method?"

"Using skin as an analogy, paper without medicine is very rough and crumbly, and the pores are very large; while paper with paper medicine has very fine and dense pores." Mu Tingxue gestured, "Even if there are hundreds of sheets When freshly produced wet papers are stacked together, they will not stick to each other and cannot be separated."

In order to be more visual, Mu Tingxue decided to use experimental methods to present it.

Yan Yang also felt that this class was very educational. Just when the teacher, the eldest princess, went to prepare experimental tools and materials, she also captured her two sons.

Behind Ya Bao and Ze Bao, there were two little tails accompanying them.

Xiao Jinyu, and Li Qian, the beautiful sixth young master of the Li family.

Four cute buns and an iceberg-faced regent.

"Your Majesty, what are we here for?" Li Qian blinked in confusion.

"My mother's teachings... make medicine." Zebao stuttered, and then nodded seriously, "Yes, it's medicine. My mother's medical skills are amazing."

The consequences of pretending to understand if you don't understand is that your head will feel a pounding and it will bulge.

The Prince Regent finished hammering his eldest son and scolded him: "It's paper medicine, a sticky medicine used in making paper."

"Uh-huh."

Zebao flattened his mouth and rubbed the bag on his head. He didn't dare to get angry or speak, and drooped his little head.

Ya Bao asked: "Dad, what do you use to make paper medicine?"

The Prince Regent remembered what his fiancee had said before and repeated it again: "Use cactus, aloe vera..."

Ya Bao tortured his soul again: "Dad, what is a cactus? My son has never heard of it."

Yan Yang was really confused.

Yes, what is a cactus?

"Could it be the palm of an immortal?" Jin Yu said in a sweet voice, "Her Royal Highness the Princess is a goddess from heaven, and the paper medicine is the method of the immortal."

The only descendant of the Xiao family, the female child Xiao Jinyu, is Mu Tingxue's number one loyal fan. When she mentions Mu Tingxue, stars will twinkle in her eyes.

Yan Yang thoughtfully said: "Probably."

Ya Bao broke the casserole and asked: "What is aloe vera?"

"I know this!"

Zebao rubbed the swelling on his head, and finally felt proud, and replied, "Last year, my mother asked the Imperial College Central Engraving Bureau to print the Compendium of Materia Medica. , does not flower or bear seeds, and has a long-lasting fragrance. When its leaves are broken, there is ointment in them. The woman smeared the palms of her hands with the hair instead of the oil."

Li Qian continued: "I have also learned that aloe vera is also known as Luobi flower, such as mountain elixir. But there seems to be no such plant in Yunhuang."

The four little buns made the regent's head grow bigger by talking to each other.

In the early years, it was painful enough for him to take care of one child, but now four appeared all at once. It was like there were four hundred little ducks in his ears, quacking all the time, and his head was buzzing. .

Mu Tingxue said she was going next door to prepare materials.

In fact, a battery-powered wall breaker that does not need to be plugged in was taken out from the space to break the sugarcane bagasse into a thick suspended slurry.

The so-called ancient method of papermaking involves soaking in running water, removing impurities with lime water, boiling plant ash, soaking, boiling, pounding, filtering, grinding and other manual methods to achieve the results of modern wall-breaking machines and separators, which take minutes to complete. Effect.

The ancients were wise and hard-working. Without the support of modern machinery, it would take them up to eight months to achieve the effect of the wall-breaking machine in twenty minutes.

Mu Tingxue poured the sugarcane slurry from the bagasse into the wooden trough, a bottle of paper medicine diluted with aloe vera gel, and seven ancient bamboo curtains for making paper. The facilities are complete and ready for experimental classes for men and children.

However, as soon as I walked into the classroom, I heard a heated discussion about the existence of cacti and aloe vera.

"It's careless."

Mu Tingxue was shocked to realize that she had made a mistake.

Yes, cactus was introduced to China through the great voyages in the late Ming Dynasty.

Aloe vera first emerged in Europe. It is recorded in the New Testament of the Bible that when Jesus Christ was buried, his saints used a mixed solution of aloe vera juice and rubber juice to smear the body of Jesus to protect the body from decay. Western missionaries regard aloe vera as a panacea. It was actually introduced to my country in the Tang Dynasty, and the aloe vera introduced to China also went through a variety mutation process and mutated into a plant suitable for growing and propagating in China.

She suddenly realized that this bottle of aloe vera gel used as paper medicine could not be easily taken out and used.

Because it cannot be widely used in the Imperial City paper mill, there is no aloe vera in Yunhuang, let alone cactus.

Next time we go back to modern times, we might as well buy some aloe vera and plant it. We can make aloe vera gel, a holy product for beauty and beauty. And it has sedative, anti-inflammatory, antiseptic, sterilizing, hair nourishing, and detoxifying effects.

"Mother is here. Mother, tell me, what kind of plant should the paper medicine be made from?" Ya Bao turned his head and saw Mu Tingxue at the door. He ran over and grabbed her sleeve. Tugged gently.

"Ahem - it was my negligence before. I forgot that we don't have cactus or aloe vera here."

Mu Tingxue actively admitted her mistakes and corrected herself to avoid giving wrong guidance to students and children. "There are more than kinds of plants that can be used as paper medicine. Let's replace them with others. Carambola vine and wild kiwi vine juice can also be used as paper medicine." Can."

This is used to make the famous Chinese rice paper.

"But it's winter now, and it's hard to find carambola vines and wild kiwis." Zebao questioned.

“Then use mountain pepper leaves!”

Mu Tingxue brought up a plant that was very common in ancient times. It also grew in patches on the mountains in the Yundu area.

The key thing is that it is the oldest paper medicine used by Cai Lun in ancient papermaking.

"This is okay! It's everywhere and it's very cheap to buy."

Mountain pepper leaves, unanimously approved.

Mu Tingxue and Yan Yang personally took the children to the back mountain and found patches of mountain pepper trees. With a hatchet, he cut down a large branch with dense leaves.
