Since Liu Hong made such a stone tablet, officials at all levels of the Three Princes and Nine Emperors had to see this stone tablet before they could enter the main hall.

Of course, for these old foxes, this little trick is nothing at all. Not to mention seeing it, even if they are asked, they must chant it once before entering the temple, and their faces will not change in any way.

This Liu Tao knows very well, Liu Hong should know better, but just to disgust them, they can do that. Under the careful tasting, this is what Liu Tao feels the most.

It's just that after this stone tablet came out, Liu Tao was ordered by Liu Yuanqi to be a low-key person. In addition, in the follow-up, no one really invited him to participate in the cultural meeting, or a party or something, and he was happy to be idle.

Time passed day by day, and in the blink of an eye, half of December was passed. The construction of a new paper mill has been completed, but unlike other paper mills, this workshop only produces toilet paper. The size of the workshop is three times the size of the original.

At the same time, the first real pieces of paper for writing had already been made. The color is similar to the color of the roasted bamboo slips, and it is not very white, but the degree of saturation is high, and the paper is soft and tough, which is a qualified writing paper.

From the beginning of production to completion, it only takes about a month, and from the second batch, a batch can be made every three days.

"How?" Liu Tao handed the bamboo paper to Cai Yan and asked her to try it out.

"Slightly better than Caihou paper, but the quality has not improved much." Cai Yan wrote a few words briefly, and then replied.

"However, it takes two to three months to complete the formal production of Caihou paper, and this only takes one month, which is the worst batch of writing paper." Liu Tao said with a smile, "The key price is less than the eleventh of Cai Hou's paper." ”

"So cheap?" This time Cai Yan was frightened, Cai Hou paper about three pieces are equivalent to a bamboo slip, that is to say, more than 30 pieces of this kind of paper is equivalent to the price of a bamboo slip.

"After mastery, especially after mass production, the price can go down even further. However, the appearance is not very good, and in the case of long-term storage, it is not much different from Cai Hou paper. Liu Tao was playing with a piece of paper, which was very unscrupulous.

In terms of quality, it is slightly better than the ingots paper of later generations, but it is not much better.

The papermaking time of more than two months is directly compressed to one month, and there is no way to force too much. Fortunately, there are other papers in the experiment at the same time, but it will take more than a month to know the results one after another.

"That's pretty remarkable!" Cai Yan suddenly found that the papers in front of him were a little noble. It's not that the quality has improved, but that the meaning it represents has changed a lot.

The price is so cheap, as long as it can be mass-produced, then the world's poor people can also have more opportunities to learn.

"Actually, it's not a big deal at all......," Liu Tao stroked the papers, "As long as the books are still in the hands of the family and difficult for ordinary people to access, then no matter how many of these papers there are, they are only used by a few people." ”

The biggest benefit of cheap paper is that more people can afford it. It's just that you can afford it, and you don't have books to transcribe, so what's the use? If you can't learn, you still can't learn, and this result doesn't change anything......

"How can you say that?" Cai Yan disagrees with this point of view, "Even if there are only more Han scholars, there will be more opportunities to read more books, and there will be more talents in the world." It's a good thing for Dahan! ”

"If you say that, it's ......," Liu Tao smiled.

This was an era when there were no public schools, and most of the so-called seowon colleges were clan studies. For example, Yingchuan Academy, which is funded by the major clans in Yingchuan for the children of the clan to study, and ordinary Han scholars are not qualified to enter.

It is true that Guo Jia is from a poor family, but the Yingchuan Guo family is also a big family, and Guo Tu is from the Yingchuan Guo family. Besides, there is no accurate evidence to prove that Guo Jia has ever entered Yingchuan Academy to study.

The public one, that is, a Taixue, and the students are basically the children of the eunuchs, so it has nothing to do with the poor family. Originally, there was a Hongdu Gate School, which developed well, and it may not be able to become a public college in the real sense, but now it is closed.

He also has a solution, but this is very offensive to the family, and the return will not be obtained until ten or twenty years later...... Slowly, this kind of offending thing, it's good for Liu Hong to do it.

You can let Liu Hong be the first initiator, so that you can do it for the second time, and it won't seem abrupt.

"What are you thinking?" Seeing Liu Tao's expression constantly changing, Cai Yan couldn't help but ask curiously.

"I just thought of a policy that would benefit the country and the people." Liu Tao said with a smile, and added by the way: It's not good for the family......

Cai Yan was very curious, but Liu Tao didn't say anything. chatted casually, led the topic away, and then signaled to go back, he planned to enter the palace while it was still early.

Cai Yan also realized that Liu Tao had other things to do, and he didn't mess around, and followed him to return to Luoyang.

The car came out of the paper mill, and the craftsmen, mainly a few masters, came out to say goodbye. This papermaking came out, proving that several improvement methods given by Liu Tao really worked, which made Liu Tao gain their recognition.

Of course, the most important thing is that with the official paper being made, they get a lot of money. At this moment, they have riveted their spirits and plan to devote themselves to other experiments.

"The weather is starting to get cooler, are you ready enough clothes to protect you from the cold?" On the way, Liu Tao asked casually. The house he rented has been built in advance, so he doesn't need to worry about keeping warm in winter.

"Originally, there were some fur coats, as well as quilts and cotton coats...... Cai Yan replied.

The cloth is a robe woven from woolen cloth, which has appeared in the Spring and Autumn Period, and it is also the dress of the ancient emperor and scholars. Maybe it's because the materials are expensive and scarce, or maybe it's a symbolic problem, so it hasn't been thoroughly popularized.

Cotton clothes are not clothes woven from cotton, but clothes filled with kapok lint. Because the yield of kapok lint is not high, the average family cannot afford to use it.

"I recently built a kang in the house, something similar to the earth dragon, do you want to build one for you too?" Liu Tao felt that this was not enough to keep warm, so he proposed, "Just take it as a thank you for helping me manage the book." ”

The earth dragon is mainly used for heating in the palace, and there is it in the palace, and the project is large and the cost is also large, and it is not used by ordinary people. In contrast, the fire kang is more realistic.

Cai Yan originally didn't want to accept Liu Tao's kindness for nothing, so it was difficult to repay the favors owed. But since Liu Tao said that he was thanks, he agreed. After all, in the winter, who would want to resist if it can be warm?

As he spoke, there was a scream outside, and then the groom fell backwards into the carriage with an arrow in his chest.

"Oops!" Liu Tao immediately attached the 'Heavenly Armor' to himself and Cai Yan, and the success of the performance also meant that they had entered a state of war at this moment.

Of course, there could be no enemy troops around Luoyang, and if there were, then it could only be - assassins!
