In the study.

After Cao Cao finished reading Cao Bin's book "Detailed Explanation of the Imperial Examination System", he was a little more calculating.

He was thinking about how to proceed with the implementation of this system.

"By the way, my eldest father heard that you founded a workshop when you were in Qian County, and you also improved Cai Hou's papermaking technique and created movable type printing, but is there such a thing?"

At this time, he remembered the previous investigation report and asked Cao Bin.

If you want to break the monopoly of the big family, you will definitely not be able to rely on the imperial examination system alone.

First of all, the price of books is far from affordable for the average person.

Moreover, if civilians can't read a single word, how can they be qualified to participate in the imperial examination?

Then, it is imperative to promote civilian education.

"Father has also heard about this? Yes, it is true, and the grandson also brought the workshop and workers to Xudu. ”

Cao Bin pondered for a moment and said, "Now, the workshop is in the courtyard in front. ”

He was a little surprised, then quickly thought.

With Lao Cao's suspicious character, after receiving Grandma's secret letter, he must have sent someone to investigate him.

In that case, the bookstore and the workshop must no longer be a secret.

If he travels to the prosperous era, these things are enough to become his heirloom and bless future generations.

But since it has traveled to the troubled times of the Three Kingdoms, papermaking and printing are not worth mentioning.

"Okay, I'm going to see what happens."

Cao Cao had long been disgusted by the beautiful smooth paper and advanced printing techniques, so naturally he would not object.

"Everyone, please come with me."

Cao Bin smiled and stretched out his hand.

Then, he led the way, walked out of the study, and led everyone to the middle courtyard.

After most of the day, all kinds of equipment in the workshop have been unloaded and returned to their respective places.

Seeing Cao Bin come in with a group of people, all the workers stood aside with their heads down.

"Foreman Zhang, can the workshop operate normally at this time?"

Stepping into the middle courtyard, Cao Bin directly found Lao Zhang, the person in charge of the workshop.

"Go back to the owner, yes."

Lao Zhang glanced at it, estimated it in his heart, and replied.

"Alright, let's get started."

Cao Bin glanced back and ordered Lao Zhang.

"Whoa!"

Lao Zhang leaned over and bowed, and then shouted loudly: "Brothers, it's time to start." ”

"Whoa!"

The workers responded in unison.

Soon, the paper department in the workshop was up and running.

In the first step, the soaked herbaceous plants such as reeds, bamboo, miscanthus stalks, wheat straw, and straw are crushed to make the plant fibers shorter and softer, and the initial degumming is carried out to facilitate the subsequent pulping.

The second step is soaked in lime water, which plays the role of degumming, dispersing the fibers and bleaching.

The third step is to repeatedly pound with a stone to enhance the firmness of the paper.

The fourth step is to wash off the mortar and impurities and increase the whiteness of the paper.

The fifth step is to groove and beat the pulp in the paper trough with a wooden rod to make the pulp fiber evenly float in the paper trough.

In the sixth step of papermaking, the pulp in the paper groove is copied with a mold frame and left evenly on the papermaking mold frame.

The seventh step is to dry the paper, and place the mold frame with the wet paper mold in a ventilated place to dry.

The final step is to unwrap the paper, tear the sun-dried paper off the mold frame, and the paper is ready.

After a whole set of processes, most of the day has passed.

When they saw the snow-white, delicate, and exquisite papers stacked together, Cao Cao and the others were dumbfounded.

Papermaking has always been a secret of all families, and the world rarely sees with their own eyes how paper is born.

Now, they saw with their own eyes that lumps of soaked turf, mango stalks, wheat straw and other roadside weeds turned into blank sheets of paper in an instant after several processes.

This scene brought them an unparalleled impact, and they had to sigh that papermaking was amazing.

"Father, this is the paper made by my grandson after improving the process of Cai Hou paper."

Cao Bin took a freshly baked piece of white paper from the shelf and presented it to Cao Cao.

"Does this paper have a name?"

Stroking the snow-white paper, as if touching the body of a young woman, Cao Cao couldn't put it down.

"I don't have a name yet, and I'm about to ask my father for a name!"

As soon as Cao Cao's voice fell, Cao Bin knew what he meant, and immediately pushed the boat down the river.

It seems that in the face of the opportunity to leave a name in history, Comrade Cao Cao is not exempt from vulgarity.

"Well, this is the paper made by your improved papermaking technique, so it's named after my Cao family, so let's call it Cao paper."

Cao Cao pondered for a moment, and soon made a decision.

“...”

Cao Bin opened his mouth and did not object.

Cao Paper, the name is so weird!

"It's breathtaking, it's amazing."

At this time, Xun Yu came back to his senses and said with admiration on his face: "Childe is talented." ”

"Dare to ask Childe, how much does this paper cost? Can it be easily promoted? Can it be scaled up? ”

Jia Xu came back to his senses, looked at Cao Bin with bright eyes, and asked.

"The cost of this paper is very low, and ordinary people can easily make beautiful paper after mastering the art of papermaking."

Cao Bin thought for a while and said, "Father, my grandson implores my father to promote this papermaking technique to the world so that the price of paper will be reduced to the minimum. ”

"If paper comes down to a price that ordinary people can afford, then the price of books will no longer be expensive."

"When the time comes, everyone in the world will have books to read, everyone will know the way of Confucius and Mencius, and everyone will know etiquette and etiquette, and then the world's talents will be like weeds on the edge of the field, and the fire will not be endless."

If you want to break the monopoly of the family, you have to do extraordinary things.

"Bin'er, you've thought it through!"

When Cao Cao heard this, his whole person became excited, and he asked in a trembling voice.

More than 100 years ago, Cai Lun invented papermaking, which made paper popular all over the world and accelerated the development of civilization.

But this technology has been in the hands of a few and has become its heirloom.

Therefore, the price of paper has also remained high, and the odd goods can live.

If he Cao Cao had mastered this more advanced and cheaper papermaking technique...

The benefits are unimaginable!

"The grandson has already thought about it, and it will be handed over to the eldest father to promote it to the world."

Cao Bin nodded without hesitation, and said in a righteous and righteous manner.

If you can dominate the world, what is a mere papermaking technique?

If you can't unify the world, staying in your hands is just making a wedding dress for others.

Just be generous and contribute to Lao Cao.

"Childe Gaoyi!"

Xun Yu, Jia Xu, and Xu Chu immediately smiled and admired them.

Cai Lun was named the Marquis of Longting for his papermaking skills, which shows how valuable it is.

It is not an exaggeration to say that it is priceless.

But Cao Bin didn't blink his eyes and contributed directly.

Such a well-understood and selfless behavior instantly moved Xun Yu, Jia Xu, and Xu Chu.

"Okay, Bin'er, you have this filial piety, my father accepted it!"

Cao Cao looked at him deeply, and his heart became more and more satisfied with this grandson.

"Father, let's go and see movable type printing again."

After handing over the papermaking technique, Cao Bin didn't bother anymore and led everyone to the other side.
