That night, inside the villa.

Everyone rubbed the paper bound books in their hands, and their faces were full of excitement and joy.

In the history of civilization on Earth, the contribution of books to the dissemination of knowledge is obvious to all. Now that this technology has finally appeared in the other world thanks to everyone's efforts, how can this sense of accomplishment not make everyone excited.

It's just that the excitement is excited, and after some deliberation, everyone has no intention of selling paper and books as commodities or circulating them.

As for the reason - that is, the impact is too great.

The Eber world is limited by the means of writing (i.e., paper), so the dissemination of knowledge is very narrow. The cost of paper that could be used to write was very high - leather paper made from skins cut from the abdomen of animals was commonly used in the Iber world. Most of them use sheep skin, but also calf skin, cherished monster skin, and even dragon skin (but the difficulty of hunting a dragon is conceivable, this is simply a job of life). Because of the limitation of the level of technology, the leather paper made by nitrate can only be used for writing on one side, and because of the limitations of the animal physique of the material, the vast majority of the paper cannot be made too large. The high cost and low practicability doom the leather paper to be not available and affordable for the common class.

In addition, since there was no printing press in the world of Iber, most books still had to be copied by specialized writers. This work requires a high level of concentration, as even the slightest mistake can ruin an entire page, and as a result, it often takes dozens of days to transcribe a book.

With such inconvenience, it is conceivable that knowledge is more often confined to the grasp of the nobility. It is really difficult for ordinary civilians to have access to real words.

And now?

With the advent of papermaking, paper is no longer a scarce commodity. Although the grass and wood paper made of grass and trees as raw materials is comparable to leather paper in terms of complexity of the process, the cost of raw materials is far lower than that of leather paper, and the output is much higher than that of leather paper. After some comparison, the cost of a piece of straw paper is only a few hundredths of leather paper. In other words, each piece of grass paper is sold at one percent of the price of leather paper, and its income is several times that of leather paper!

What's more, with the advent of block printing, a well-engraved and confirmed engraving plate can rub countless books with identical plates. And there is no need for a writer who is good at writing, just a dexterous worker, who applies ink to the carved tablet and then covers a piece of paper and compacts it, can transcribe an article - even a farmer who can't read a lot of words, if he is not stupid, can do such a job after a few days of training in the workshop!

In this way, although the dissemination of knowledge is still limited, it is not something that can be absolutely monopolized by the human ruling class of the world of Iber^.

And in today's world of Iber, one of the dependencies relied upon by the ruling class^ to cultivate their cronies and grow their power was the absolute control over the imparting of knowledge.

In the nearly 1,000-year history of the southern city-state of Tristram, in addition to the rebellions of some noble lords, there were also several uprising^ wars involving the poor and slaves on a wide area. It's just that the 'uprising^' of these commoners is often suppressed by the kingdom faster than the rebellion of the lords^. Because these civilians rose up after the rod, because of the lack of knowledge, there was no capable enough leader to lead the subordinates, and there was no capable subordinate to assist, they only relied on the sudden bloody qi to create a temporary wave in the human city-state, and then they would be quickly extinguished.

Today, however, the advent of papermaking and printing has made it possible to disseminate knowledge on a large scale. This is something that can be used to earn wealth and cultivate talent for the ruling class^ class, but it is also something that will shake the very foundation of its rule. For the nobles of the human ruling ^ class of the world of Iber, everything that shakes the very essence of their rule, they will do their best to erase it, no matter what the other party may be.

For the current traversers, their strength and power are still too weak. It was obviously dangerous to be an enemy of the aristocracy of the entire kingdom, and even the Leopold family, who now sheltered them, could not afford it. What's more, Kasha, who is also a member of the aristocratic class, may not help them out of his own considerations when facing this matter.

Therefore, it was unanimously decided that all the facilities and equipment and research and development materials of papermaking and printing technology should be temporarily sealed in the secret vault in the basement of the villa, and they would wait for the right time to release it.

As for the craftsmen involved in the research and development, everyone did not wipe them out. For reasons of secrecy, all the processes were developed by craftsmen who may know each other, but they do not know that they are also involved in the development of papermaking or printing. What's more, they are just traditional craftsmen, and they have no idea what kind of impact these two things will have on the whole world. Moreover, because of the natural sense of reverence that the lords of the Iber world had for the lords, they did not dare to ask the meaning of the work that the lords had made them do, and they simply did what they were ordered to do. So after being given a gag order and then a bounty, these happy people went back to their homes to run their own businesses, completely forgetting about it.

"Mountains of gold are piled up in front of you, but you can't reach them. It's a terrible feeling. "I watched as the finished objects, manufacturing equipment, and all related materials were put into the vault, and the locks were sealed. Li Xiang smacked his lips and said regretfully.

"The husband is not guilty, but he is guilty." Yang Qianyu patted Li Xiang on the shoulder and persuaded: "Now we are still too weak. As long as we are strong, then these things will become our source of wealth in the future. ”

Li Xiang shrugged his shoulders and said he understood.

After sealing all the facilities and materials related to papermaking and printing, the lives of the people who traveled through the world resumed their old daily life of "training, entertainment, and business".

In the blink of an eye, more than a month has passed, and as spring approaches, the weather is starting to get warmer.

However, the occasional visitors to the Château de Prairly began to find that the atmosphere in the castle had become gloomy, and the soldiers of the Knights were all fierce and ready for battle.

The curious crowd wondered why the atmosphere in the castle was so tense. The warriors told them that this time of year, while it was the best time of year for spring ploughing, was also the time when the wilderness wanderers in the southern part of the kingdom began to stir up and prepare to plunder.
