I do research in ancient times

I have to say that Aunt Niu is extremely talented in cooking.Although the soy sauce was brewed under Ning Fei's guidance, Ning Zhizi himself does not know how to cook, and Aunt Niu did all the subsequent use and dish development.

The retreat is not for nothing. Three days after the birth of soy sauce, Aunt Niu was like a newborn, and directly threw a new menu in the dining room.

Many of the dishes on this menu later became Ning Fei's main force in entertaining the Feng family brothers, and became Xiaodi Feng's favourite.

Hearing that the young masters in Ding'an City ate full of praise, Aunt Niu became more confident.She intuitively found a new direction for development, combined with her previous experience in making and using sauces, and invented some dishes with unique styles.

Among them is the sauced tofu.

Tofu is the most common ingredient in Mozongwu Castle. The taste of tofu is bland and plain. It seems to be versatile, but it takes a lot of effort to make it well.

The disciples of Mo Zong worked daily and got used to the strong taste early in the morning. Now they have replaced it with tasteless tofu. At the beginning, they still ate it fresh.

Sauce clam tofu is the earliest recipe invented by Aunt Niu. It uses her most convenient sauce frying method, and it is very popular once it is launched.But I don't know why, Aunt Niu always feels that something is missing, and there is no obvious improvement after several attempts.

Until one day, the planting team sent the newly harvested peppers to the dining room, and Ning Sawzi, who had nothing to do, suggested that Aunt Niu make some chili oil.

At the moment when the hot oil was poured on the red powder, everyone in the audience could feel that Aunt Niu exuded fighting spirit and ambition visible to the naked eye.

Ding'an City, I've got it.

"Delicious! Delicious!"

The young Juntun had a mouthful of tofu and a mouthful of steamed buns, his forehead was covered with beads of sweat from being spicy, but the expression on his face was extremely cheerful.

"Grandpa, do you eat this every day? It's too good for you!"

Hearing what he said, several military camps nearby also responded.

"Although it's not expensive food, the taste is different!"

"What is this spicy thing! Why do you want to eat more and more, and the more you eat, the more you become addicted?"

"No, I can't stop, I added another bun!"

Although he guessed the result early in the morning, old man Liu was still very happy when he heard the other party praise Zongmen.

"It's called chili peppers. It's a good thing that our planting team has grown. Don't you feel sweaty after eating it? That's right. This thing can keep out the cold and dehumidify, and it's useful!"

I heard that it was planted, and several military villages thought it was miraculous.

Mo Zong has only been outside the pass for a few years, and it can't compare with the time they have spent in military settlements for generations. How can they grow this new thing.

No wonder the Eldest Young Master wants to recruit someone to listen to Mo Zong, Mo Zong does have two talents.

"Where is this?"

Old man Liu continued to be modest.

"Young people just can't hold their breath. You will be surprised when you really go to school."

Lao Juntun felt that the Mozong brothers were a bit bragging.

He is different from those boys, he has seen the world.He has seen all the water dragons built by Mo Zong in Jiuling Lake, what could be more surprising?

But when he really entered the school, Lao Juntun realized that he still underestimated the group of old boys like Mo Zong.

It turns out that the tables, chairs and dining rooms were just a stepping stone, and the real big move is still to come.

After lunch, the teaching of Mozong's agricultural science officially began.

When 30 soldiers entered the classroom, they found that some objects had been placed on the empty table.

"what is this?"

Lao Juntun sat down at the table, his eyes fell on the palm-sized square and charcoal pen.

This square is bound with thread, and there are layers of layers inside. I don't know how many sheets have been ordered. It feels smooth and delicate.Like cloth and not cloth, like silk but not silk, as thin as a cicada's wing but flat and stylish, Lao Juntun has never seen such a miraculous thing.

"This, this, this... what is this?!"

He looked at Old Man Liu standing on the stage, and his voice was rarely broken.

"Are these one by one cloth?"

Lao Juntun is old and experienced, and he is the same as Dinghaishenzhen among this batch of students.Can make him lose his composure in this way, the attention of other army camps was immediately attracted.

I was too busy studying charcoal pens just now, and didn't pay attention to another thing.Now listening to what the old army said, everyone realized that they almost missed the biggest treasure.

"You...you Mo...Why is Mo Zong so arrogant? You...you actually issued silk calligraphy for...students?!"

A middle-aged soldier shouted involuntarily.

"This... this thing... no, no, it's not only a man of a family who can afford it?!"

"what."

Old man Liu raised his head and chest, showing off in a low-key way.

"What aristocratic family can afford it?! Does the aristocratic family have two more hands than us?!"

"It's not cloth, it's called paper, it's made by our sect itself. Mo Zong's son Kaimeng uses a sand table, and he can only write on paper after he has learned it. It's a test of kung fu compared to silk and bamboo slips!"

"Because it is a secret treasure of Mozong, the output is not much, and the book can't be given to you for the time being. It is only for you to record and answer questions, and you will have to take it back when you leave."

"So, the dry goods still have to be kept in your head and in your heart, and you can take them back when you leave, and you can use them anytime in the future."

As he spoke, he took out another large notebook from his arms, and flipped through a few pages.

"I also have a book called handouts. My old man will give you lectures based on what's on here."

"You will also have a copy in a while. I will focus on it. You can review it after class. But be careful to keep it. If it breaks, you will pay for it. When you leave, you have to keep it for the sect."

"Don't underestimate our farm school, it's no worse than those schools for aristocratic families to lecture on scriptures!"

Being boasted by old man Liu and amazed by the papers in the army station, in Ning Zaozi's view, it was not a successful attempt.

Before, he bragged in front of Brother Mu Ye, saying that the situation in the world was unclear, and now it was not the time for paper making, and farming was the most important thing.

As a result, within two days, Ning Shaozi slapped himself in the face.

There is no other reason, the birch forest on Niubei Mountain is going to be bald.

Recently, Mo Zong's birch bark was consumed a lot. Clay took a group of children to look for woods all over the mountains, but the bark paper he collected still couldn't meet the demand.

Investigate the hydrological records of the Wuzhi River, topographic survey maps, Jiuling City pipeline construction drawings, design of hydraulic looms and hydraulic hammers, all that need to be recorded must be bark.Hua Tu Ning Saw can find Yu Xin as a laborer, but the bark does not grow right away.Seeing that the tree is about to hang up again, the reality does not allow Ning Saw to be hypocritical.

Ning Fei also thought about using bamboo slips to make a living, but the extremely unfriendly way of writing made the saw directly overturn the table. Live!

Ah... yes, we still have to make paper.

But I have let the words out before, and now is not the time to make paper...

After thinking and thinking, in the end he still fell to his knees in front of the gradual backlog of work, Ning Zazi wept bitterly while hugging his swollen face.

Just... just make some paper, just make a little, and don't spread it to the outside world.

So, the cheeky Pi Ning saw himself off, and found a small team of engineers that he was used to, and began to study papermaking.

Making paper is easy to say, but when you start to do it, you still encounter a lot of small troubles.Although Ning Fei knew the method of making paper, the plants suitable for making paper in the previous life materials did not exist in Niubei Mountain. What can be used as a substitute needs to be tried by a small team.

Therefore, Clay, the "little overlord of Niubei Mountain", once again played a role, leading a group of "little brothers" to haunt around, and used this as an excuse to skip class for three days, providing the papermaking project team with a lot of plants that could be used.

In the end, Ning Fei chose asparagus from the west slope of Sanchagou.

Asparagus is the most common weed outside the Great Wall. It is cold-resistant and has strong vitality. It often covers an entire hillside when it grows.

Asparagus has slender fibers and tough leaves. As long as the roots are not damaged, even if the leaves are cut off, they will grow rapidly. It will not cause great harm to the environment when used as a substrate.

According to his experimental comparison, the cellulose content of asparagus is the highest among many herbaceous plants, almost equal to that of the woody masson pine, and it is easy to bleach, which is very suitable for papermaking.

Of course, using wood to make paper, the quality is better.However, forest trees are not easy to grow, and once they are damaged, they cannot be restored in a short period of time. I would rather not start with ecological damage.

With the materials, the papermaking project team began to make trials according to the process provided by Ning Saw.

Soak, smash, cook, rinse.Adding water to make pulp, flattening, drying and cutting, the first batch of paper in history was successfully born.

Birth is birth, but these experiments are not perfect.

Too much water is added when mixing the pulp, resulting in abnormally sparse paper, and in some places there are still fibers that are not completely crushed, the thickness varies greatly, and the paper surface is not smooth enough.Unwilling to fail, Ning Fei tried to write on it with ink, but the ink smeared into a large area as soon as it hit the ink, which was horrible.

Although under his guidance, all the disciples of Mozong have changed to charcoal pens, and it doesn't matter whether they smudge or not when writing on paper with charcoal pens.

But Ye Chao's most mainstream way of writing is still pen and ink. As a Virgo with a slight tendency towards perfectionism, sending this batch of paper out to meet people is tantamount to scratching the face of Ning Saw.

no!no!no!

Apart from being cheap and thin, there is no selling point. Ning Fei firmly refuses to accept this kind of product!

As a result, this batch of black history was hidden as soon as it was born, and became toilet paper in Ning Sawzi's bathroom.Not to mention, if it is used in the toilet, it is thin, sparse and highly absorbent, but all of these have become advantages, and whoever uses it is the best.

As a result, gossip circulated among Xinshi, saying that Juzi had recently suffered from internal hemorrhoids and frequently went to the toilet.

Using the fetish of juzi can refresh the body and mind, strengthen the body, and can also eliminate odor and relieve diarrhea.

Ning Fei was so angry that he was so angry that he almost had trouble going to the toilet.He uttered a word that he would make some good paper for everyone to see, and then he plunged into the personal laboratory converted from the boy's room, not knowing what he was thinking about.

Heh, the ancient method of papermaking is not easy to master, so he should improve it.

The pollution caused by papermaking mainly comes from the pulping process. The traditional method of making straw pulp generally adopts the alkaline method and the sulfurous acid method. Not to mention the large amount of wastewater discharge, the water also contains many harmful substances, which seriously pollute the environment.Asparagus has a characteristic, that is, it contains very high cellulose, so Ning Fei’s idea is to introduce white rot fungi into the pulping process to biodegrade impurities such as lignin and fructose gum to make clean and non-toxic pulp. Contaminated pulp.

So, Clay dispatched again, and went all over the mountains and plains to find rotten logs with white hairs for Juzi.

As for the wire department and pressing, this requires the cooperation of the carpentry class and the blacksmith workshop.

Smashing and crushing can be done by borrowing the discarded small crushing hammers from blacksmith workshops, and there are ready-made coke ovens for drying. The residual temperature of coke cooling is enough to dry paper.

Ning Zaozi took Liu Tong and Liu Tie, two capable subordinates, and spent three days making a fourdrinier perforated flat screen. In order to adapt to the large-scale production that may appear in the future, Audio-Technica also made paper molds for movable curtains and beds. , referring to the model of the loom by the way, a simple paper assembly line that can be operated by a single person is created.

All is ready except for the opportunity.

Clay still lived up to expectations, and finally found the white rot fungus Ning Juzi needed among the mountains of rotten wood.

Cultivation and screening of strains, Zha Tong has made great efforts this time.According to the characteristics suggested by Ning Fei, it uses the system species evaluation panel to directly pick out the more suitable pulp-making flora in the colony, which greatly saves the screening time.

After so much effort, the second batch of paper was finally produced.

This time Ning Fei worked hard, from pulp to paper, he personally participated in every link, and the results were very good.

The paper is still light, thin and smooth, with very good flexibility, but because it has not been bleached, the color is slightly dark yellow.

Ning Fei was not very satisfied with this point, but the actual result was enough to amaze everyone in Mozong. It was only a thin sheet, but it could be folded and twisted at will, which made everyone amazed.

"Bring a pen and ink."

Ning Saw nodded and decided to test the most critical part.

He took the Langhao handed over by Clay, raised his pen and wrist, and wrote the word "ink" on the flattened paper.

Smooth to the touch, clear writing, no seepage, no smudge.

"It's done!"

Liu Tong cheered.

"A great talent!"

"This thing is cheaper than silk and lighter than bamboo slips. If it is spread, the world will be crazy about it!"

"I didn't expect that weeds outside the Great Wall can be made so smooth and clean! It's amazing!"

Liu Tie scratched his head, "...Juzi, is this thing also made of paper?"

He seemed to have thought of something, and asked in a low voice.

"Using this thing to wipe it is too wasteful..."

Because of the oolongs in paper making before, most of Mozong's disciples now firmly associate "paper" with "toilet", thinking that things like "paper" can only be used in latrines.

Ning Fei couldn't hear these words the most, he glared at Liu Tie, and felt that he had to correct this unhealthy trend.

He thought for a while, raised his pen and wrist again, and wrote a letter in his own hand.

The letter was addressed to Mr. Feng, and another piece of paper was used as an envelope, stamped with mud, and handed to Liu Tie.

"Go and send it to the Protectorate of the Metropolitan Government. Use your eyes to see clearly the true value of this paper!"
