"Gu Gongzi don't want to make fun of it, our father and son are also hot-headed for a while, so they did such a whimsical and ridiculous thing. Otherwise, it would not have ended up like this. ”

Zhang Zhaocai looked embarrassed. He just thought Gu Ren was joking, and he didn't take it seriously.

"Uncle Zhaocai, since you and Brother Jinbao are preparing to produce paper in the workshop, you can bring me a wooden barrel and two pieces of cotton cloth, two planks, and a glossy square piece of iron. I'll try it first and see if it works. ”

Gu Ren didn't say much. It was also the first time he had done this experiment, and what was theoretically feasible was not necessarily feasible in practice. Therefore, if it is successful, it will be a big talk.

"This ......"

Zhang Zhaocai was a little embarrassed, this wooden barrel and wooden iron block are easy to say, worthless things. The two pieces of cotton cloth are a little distressed. This is the Tang Dynasty, and there are probably two kinds of cloth for people's clothes, one is silk and the other is linen. Although cotton cloth is sold in the market, it is quite expensive because of the low production.

"Uncle Zhaocai, just buy it according to what Senior Brother said."

Dandan handed the money bag in his hand to Zhang Zhaocai.

"Well, I'll buy it."

Zhang Zhaocai was not polite, and took the money bag that Dan Dan handed to him. I went out of the yard and went to buy cotton cloth.

"Uncle Zhaocai, go to the pharmacy and buy some sulfur and yellow gum."

Gu Ren explained again.

"Okay."

Zhang Zhaocai responded.

In less than a stick of incense, Zhang Zhaocai came back from buying cotton cloth and sulfur powder, and Jinbao prepared wooden planks and barrels.

Gu Ren began to experiment, Zhang Zhaocai's father and son, and Dan Dan gathered around and watched carefully. The two little children under the eaves also surrounded curiously. Zhang Jinbao glared at them, and they left unhappily and went to play on the other side of the fence.

Gu Ren scooped a few spoonfuls out of the pool, and took a wooden stick and stirred it a few times to see its viscosity. Even in later generations, papermaking refining must reach a certain degree of deduction to ensure the normal operation of the papermaking section. Not only that, the finished slurry must also go through slag removal, screening, washing and other sections to remove impurities in the slurry. Gu Ren is just a simple experiment, there is no need to make it so complicated.

To prepare the pulp, the first step is to filter it with a cotton cloth, and after adjusting the consistency, the loose pulp is beaten and glued.

When this is done, use a small spoon to come out and pour it evenly on a flat wooden board. I made a palm-sized piece. After a little solidification, flatten it with another plank. Then press it with a small black piece of iron.

It's noon, and the temperature is not bad. Gu Ren took out a magnifying glass from the package and focused on the small piece of iron.

"Gu Gongzi, is your method feasible? So you can make paper? ”

Zhang Zhaocai and Zhang Jinbao were a little puzzled. When they were in the official workshop in Shaozhou, they saw the process of producing paper. It's time-consuming and complicated. But the profits are super high. Otherwise, they would not have moved the idea of opening a small papermaking workshop. Unfortunately, they didn't learn some of the necessary secret procedures, and the cost of investment was too high, and they ended up like this.

Now this nephew's senior brother can really make paper with such a few simple things? They still don't believe it from the bottom of their hearts.

"It's hard to say."

Gu Ren smiled slightly, and let the magnifying glass continue to heat up the small iron block.

Soon, a white vapor floated up, and there was a faint hissing sound on the iron.

"Wow, what kind of treasure is that, that can actually heat up a piece of iron? It's amazing. ”

Zhang Zhaocai's father and son looked surprised.

"It's called a magnifying glass, and it focuses the light on a focal point."

Although Gu Ren knew that they wouldn't understand it even if he explained it, he still said it.

As the hissing water vapor floated up, and after the small corner that was exposed was no trace of water, Gu Ren moved the large mirror. After the procedure is completed, the success of this experiment will be revealed.

Gu Ren was a little nervous and excited in his heart, and carefully picked up the iron block.

On a wooden board, a piece of white paper is glued to it. It looks good, and it's a piece of paper. It is only slightly yellowish, and the sulfur bleaching effect is obviously weak. However, he does not yet know how thin and thick the elasticity and toughness are.

"It's so white. I just don't know, it's stuck together. ”

While Zhang Zhaocai and Zhang Jinbao were amazed, they were a little worried that the paper was scattered and would be broken when touched.

"It should be fine."

Gu Ren tore open a small corner and blew it lightly, and a palm-sized piece of paper fell from the wooden board and landed in his hand. Thin as cicada wings, white and shiny, but also exudes a faint luster.

Gu Ren's fingers flicked lightly, and with a snap, it was not broken, the paper was as new as ever, and the toughness could be seen.

"Wow......"

"Oh my God!"

Zhang Zhaocai's father and son's eyes lit up, and they were completely shocked. Is this really paper? They couldn't believe it at all, even the paper in the Shaozhou official workshop was not so good, there was such a white, smooth, and resilient paper in the world. It's incredible.

Dan Dan was also surprised, he was a little mixed up in the tall circle of the second generation of officials and the rich second generation, and he saw a lot of strange things. But this is the first time I have seen such a thin, white, smooth and tough paper. This is completely comparable to the best bamboo paper in the royal family, to be precise, bamboo paper is not seen as good.

"Uh, it's a bit thick, it's too rough...... What a failure......"

Gu Ren was very dissatisfied and rubbed the paper in his hand in his palm, crumpled it into a small ball, bounced it out, and flew into the pool.

"Don't!"

"Don't!"

"Ahh

Zhang Zhaocai Zhang Jinbao and Dandan shouted almost at the same time, Zhang Jinbao even flew out, grabbed the paper ball in the air, and fell into the pool with a thud.

"I continued, scared the hell out of me, hahaha."

Zhang Jinbao wiped the sticky pulp on his face, stood up, and raised his other hand high, grasping it tightly, for fear of getting wet.

Zhang Zhaocai and Dandanchang breathed a sigh of relief.

Gu Ren was stunned, and he hadn't figured out what was going on with this scene.

"Senior brother, you are too extravagant and a loser."

Dan Dan took the small paper ball from Jinbao's hand, carefully stretched it out, and Zhang Zhaocai also glanced at Gu Ren a few times dissatisfied.

Gu Ren couldn't laugh or cry, the quality of this paper was basically the same as the hemp paper of later generations.

"Dandan,

This one is not good, lose it, and make one from it. ”

Dandan unfolded the paper and raised his head to look at Gu Ren.

"Senior brother, I can't help it. It's more precious than gold. Let's go into the house and let Brother Jinbao change into clean clothes. ”

"Hey, I'm fine..."

Jinbao pushes.

"Let's go inside. It's pretty sunny outside, too. ”

Gu Ren said.

"How much money is this paper in Qujiang?"

Dandan: "Ordinary one-foot square paper is five cents, and as for this quality, it is priceless." ”

"Wow, so expensive?"

Gu Ren was taken aback, a little surprised, he could buy two steamed buns for one penny, and five pennies was equivalent to ten steamed buns, which was the food money of ordinary people for two or three days.

It is no wonder that Prince Xin and Prince Ji set the consumer group of Journey to the West publications as the children of officials and businessmen.

Dandan: "Senior brother, although this piece of paper is expensive, it also represents another more important meaning. ”

Gu Ren: "Let's hear about ......"

Dandan: "Senior brother, this small piece of paper represents the birth of a great invention and creation, an epoch-making significance, and a great contribution to the scientific and technological productivity of the Tang Dynasty to be at the forefront of the world to a new level!" It's like a newlywed's first red sheet, and the meaning is extraordinary! Is that right? ”

Dandan's tone was high, passionate, and he looked like Gu Ren was talking big on weekdays.

"Yo, you've learned well! Continue! Hey, speaking of this rolling sheets. It seems like it's time for us to go back...... Don't we have big things to do? ”

Gu Ren thought of the "big event" of the night, he didn't have to wait for the newlywed to be able to roll the sheets with the goddess......

"yes."

Dandan also thought of Gu Ren's big event in the evening.

"Gu Gongzi, what about making a fortune?"

Zhang Zhaocai's father and son looked at Gu Ren with expectant eyes, they now fully believed that Gu Ren could make them rich and buy a villa.

"Of course, the matter of getting rich cannot be delayed, and later you will do what I say, and in a few days, your pool of water will be turned into white and pure paper. If you sell it again, it's not just white silver. ”

Gu Ren smiled.

"Very good! Thank you so much, Childe, you are simply our savior, please allow us to bow to father and son. ”

Zhang Zhaocai and Zhang Jinbao bent down to thank them, but Gu Ren supported them.

"Uncle Zhaocai, Brother Jinbao, don't be polite, Zimo and I are brothers, this is nothing. Pack up here and get what you need. Next, your little ideal workshop will be established! Soon, a lot of silver will fly into your pockets, and soon, you will be able to defeat Gao Fushuai and chase Bai Fumei, and embark on the small peak of life......"

Gu Ren laughed.
