After a long history, it was not until the Jin Dynasty that the manufacturing process of paper was fundamentally developed, and the variety, output and quality were increased and improved, and the source of papermaking raw materials was wider. It was not until the Sui and Tang dynasties that the papermaking process began to gradually mature and became truly popular.

However, the paper produced under the guidance of Lu Yunzhou, a later generation, has naturally skipped countless twists and turns in the intermediate development stage, and is directly manufactured with a mature process, so the paper is made at a low cost, not to mention the quality, which is naturally very good!

Tian Dan took a deep breath, there was a look of shock in his eyes, and he couldn't help but show a smile of ecstasy on his face, looked at the stacks of bamboo slips on the bookcase, and sighed in disbelief: "The nine articles of the "Sutra Yan", if it is engraved on the bamboo scroll, it is enough to fill this bookcase, but it is written on this small paper, but it only needs such a thin volume, it is really unbelievable, it is as light as a silk book, but it is not as expensive as silk silk, and the output is scarce, but it is low in cost, and it can be mass-produced!"

In the era before the advent of papermaking, people mainly used bamboo slips to record words, but bamboo slips were too bulky and inconvenient to carry, such as Qin Shi Huang's one night to read the chapter had to be pulled by three cars; Dongfang Shuo in the period of Emperor Wu of the Han Dynasty, when the emperor wrote to the emperor, he often had to load several large carts of bamboo slips. Therefore, some confidential official correspondence, emergency military information, letters between nobles, etc., are all written in silk script, that is, the text is recorded on silk silk.

Silk book is also known as silk book, the Warring States period before the silk fabric for silk, including brocade, embroidery, silk, Luo, silk, silk, Qi, silk, etc., the cost is expensive, the output is very low, because of its preciousness, silk silk in ancient China, and even used as physical currency for a long time.

Generally, only the aristocratic and wealthy families can afford to wear silk clothes and use silk books. Ordinary solid people can only afford to use bulky bamboo slips, which is very inconvenient. The poor, on the other hand, have no access to education.

But even the aristocratic and wealthy families could not be willing to use precious silk to record an entire book, or use it for daily writing, which is equivalent to using gold to record words, or consumable use, this kind of extravagance, even if it can be used, no one can waste it so much.

Although the material of the bamboo slip is not very valuable, it is not used by the people at the bottom, and the manufacturing process is also extremely troublesome, and the handwriting is easy to fall off - unless the words on the bamboo slip are engraved, they will be scraped with a knife. Therefore, in this era, whether it is reading or writing, it is an extremely luxurious behavior, and even some ancient historical materials and articles are memorized from generation to generation, passed down by word of mouth, and passed on orally, which is very easy to be lost. In this era, almost all of the education methods were passed on orally or through chatting.

To put it bluntly, the knowledge of this era is still in the hands of the aristocracy, even if Confucius advocated education without class, founded private education, broke the education monopoly of the government, and made Confucianism committed to popularizing education to the common people since then, but the scope of such private education is also very limited. In this era, most ordinary people are still illiterate.

At this moment, it is completely conceivable that once the cheap writing material of paper can be popularized, it will trigger a series of chain reactions, which will not only greatly facilitate the recording, storage and transmission of words, but also promote the wider dissemination of knowledge, so that more people have the opportunity to learn, improve the overall literacy rate of the people, and the expansion of the scope of education will lead to an increase in the national talent pool, and will also indirectly promote the prosperity and development of the country.

Tian Dan took a deep breath, suppressed the excitement in his heart, turned his head to look at Lu Yunzhou, and asked cautiously: "Qi Yu, what are you going to do with this paper?"

Lu Yunzhou said with a smile: "If there is any place in the country that needs paper, our Qijia Workshop can give priority to supplying it to the country at cost price!"

Tian Dan thought about it for a while, nodded with a smile, and didn't do much reluctance, since it was provided to the country at cost price, then it would be worry-free to hand over this matter to the Qi family.

Although Lu Yunzhou did not contribute the manufacturing process to the imperial court, it was already very sincere to be able to give priority to supply at cost price!

After all, with the strength and confidence of the Qi family, the manufacturing process is in their hands, even if they take the opportunity to ask for more benefits, no one has a way to take them, and the manufacturing process is the foundation of their lives, and the Qi family is unwilling to take it out, but it is also human nature.

Of course, Lu Yunzhou is willing to make such a concession, naturally hoping that Qi can correspondingly provide some protection for the development of Qi's paper industry.

There is no airtight wall in this world, now that paper has appeared, the mature papermaking process is not complicated, in fact, it is not difficult to steal the craft, and even according to the collection of raw materials by the Qi family, it is not difficult to scrutinize and explore the complete manufacturing process step by step. Therefore, if the paper industry of the Qi family can be protected by the government, then at least in the Qi country, it is impossible for the merchants of the climate to dare to steal the manufacturing process and come out to compete with the Qi family, and some small deals, whether it is quality or price, can not compete with the Qi family.

Once the emergence of paper, a convenient and cheap new writing carrier, it is bound to trigger market rush and bring broad market demand.

If the Qi family can monopolize the paper industry in this era, then the huge profits are obviously unspeakable. From this point of view, Qi household cost price for the state free supply of paper, first of all, there can be no loss, but indirectly from the huge benefits.

"So it's decided, it just so happens that your uncle is also in Linzi these days, and the specific recruitment, site selection, supply and other matters, this minister will personally talk to your uncle!"

Tian Dan put down the "Nine Chapters of the Pipe < Jingyan> in his hand with satisfaction, picked up the letter again, observed the fire paint seal on the mouth of the envelope, guessed that it was probably similar to the sealing mud, and picked up a knife on the bookcase to cut the fire paint seal.

The envelope was opened, and there was a thick piece of folded letter paper inside, Tian Dan opened it and looked at it, his eyebrows were raised, and he saw three tall and powerful characters written at the beginning of the letter--

"Imperial examination system!"

Tian Dan narrowed his eyes and suddenly became serious, if nothing else, unlike some specific measures, once the policy enters the field of the system, it will have some fundamental impact.

Just like the tuntian system proposed by Lu Yunzhou before, Tiandan has to attach great importance to it.

Now that the huge benefits brought by the Tuntian system to the Qi country have only revealed the tip of the iceberg, in such a short period of time, Lu Yunzhou has actually figured out a new major move?

Lu Yunzhou's demonic performance before made Tian Dan suddenly have extremely high expectations for the specific content of this imperial examination system.
