There were no ceremonies, and there were no ceremonies, and an inconspicuous institution was established in the imperial city in silence, this institution was called the Royal Printing Office, as the name suggests, that is, a special place for printing books, and the set of copper movable type brought by Li Xiu was also placed here.

"Pony, it's done!" Several craftsmen came over carrying a wheel-shaped thing, and then saluted Li Xiu, who was busy.

Li Xiu also raised his head when he heard this, and then looked at the huge "wheel" in front of him, only to see that the bottom of this thing was a huge disc, which could stand on the ground, and there were four layers of discs on the top, which were divided into grids one by one, and each grid was also marked with some symbols of sound rhyme, of course, it was not the pinyin of later generations, but was divided into various areas according to the book "Cut Rhyme" of the Sui Dynasty.

"It's good, put the copper movable type in the grid of this roulette wheel according to the sound rhyme, so as to make it easy to access!" Li Xiu turned the steamer on it and immediately commanded.

The other craftsmen immediately agreed, and then set up the special roulette wheel in the printing room, and the box next to it had been opened, and the layers of copper movable type inside were also picked out and placed in the roulette wheel. It is worth mentioning that there are a few of these craftsmen who are born as scholars, and they don't have to do anything else, they just need to teach the craftsmen how to classify the characters according to the sound rhyme, and then guide them to quickly find the font they need with the sound rhyme.

He is now pondering the problem of typesetting and printing, he has already selected the size of the book, and has made several square shallow wooden plates according to the layout, so that the number of copper movable types placed on each page is fixed, and the typesetting is also very compact.

However, after printing many times, Li Xiu found a problem, that is, the wooden plate is still not enough to fix the movable type, and because of the problem of technology, the specifications of the copper movable type still have some small errors, these errors can not be seen on the surface, but when a plurality of movable type is lined up together, these small errors will be magnified countless times, especially after many printing, the gap between the movable types will still change, which will affect the printing, and the layout is not regular, and it is easy to dye the paper.

Finding this problem, Li Xiu is also thinking about how to fix the movable type, after all, a version of the movable type needs to be used many times, for example, Li Shimin wants to print 10,000 copies of the clan chronicle, so even if it is the most ideal state, the movable type version also needs to print 10,000 words, not to mention that there may be unqualified paper, so the number of printing is definitely more than 10,000 times, so frequent use, the movable type must be fixed very firmly.

The above problem seems simple, but it is very troublesome to solve, for example, engraving printing will not have this problem, because the whole printing board is a whole, but the movable type is separated, Li Xiu also considered using leather rope or movable wooden frame to fix, but the effect is not ideal.

Later, a craftsman proposed a solution, that is, to turn the wooden plate containing movable type into a copper plate, and then put rosin or wax in the copper plate, and after arranging it, the copper plate was placed on the fire to roast, so that the rosin or wax inside dissolved, and when they solidified, the movable type was naturally fixed as a whole, so that there was no need to worry about the loosening of the movable type.

The above is only one of the problems that arise in movable type printing, and there are some other problems that have also been conquered by the wisdom of these craftsmen, which makes Li Xiu sigh: the wisdom of the masses is unlimited!

The principle of movable type printing is very simple, although there will be some problems in the actual use process, but there are also solutions, even if they can't be solved, you can also come up with alternative methods, so half a month later, the printing office is also ready, and the printing of the clan chronicles is also on the agenda.

"Your Majesty, the printing office has been prepared, and now we will hand over the original of the clan chronicle to us, and then start printing!" On this morning, Li Xiu specially came to the Liangyi Hall to report to Li Shimin, but to Li Xiu's surprise, in addition to the eldest grandson Wuji in the hall today, Li Chengqian was also here.

"Then what are you waiting for, Mowgli, you quickly let people take the clan chronicles, strive to print the clan chronicles as soon as possible, and then distribute them all over the world, and then everyone will have a clan chronicle, I see what those families can do!" When Li Shimin heard Li Xiu's words, he immediately got up, and said loudly with a very excited expression.

"Hehe, it's finally time for this day, since the horse is preparing for the printing office, I have asked people to copy a copy of the clan chronicle and keep it by my side, and now I will let people get it!" The eldest grandson Wuji was also happy when he heard this, and after speaking, he turned around and went out of the hall to let people take the clan chronicles.

"Father, sir, what is the printing office, and what does it have to do with the clan chronicles?" However, at this moment, I saw Li Chengqian asking with a puzzled face, only Li Xiu, Li Shimin, and the eldest grandson Wuji knew about movable type printing, and the establishment of the printing bureau was even more low-key, and the craftsmen selected were all sent out of the prison, and there was no need to go out of the palace to look for it, so even Li Chengqian had never heard of it.

"Haha~, the matter of the printing office is a long story, but since everything is ready over there, I also want to go to see the printing process of the clan chronicles in person, why don't we go to the printing office together to take a turn, and then you will understand!" Li Shimin immediately laughed again and said, since the fight with the family, he hadn't laughed so freely for a long time.

Hearing Li Shimin say this, although Li Chengqian had a stomach full of questions, he didn't say anything more. At this time, the eldest grandson Wuji had also taken the clan chronicles. The clan chronicles record two hundred and ninety-three surnames, one thousand six hundred and fifty-one, although it seems to be a lot, but in fact, the clan chronicles are not thick, and even a little thin, but who would have thought that it was such a thin book, which would provoke a fight between the royal family and the family.

Li Shimin wanted to visit in person, Li Xiu naturally would not refuse, when the group went out of the Liangyi Palace, and Li Xiu also found at this time that although Li Chengqian was trying very hard to cover up his foot disease when he walked, he could still see it, which made him sigh, although he tried his best to help Li Chengdao recover with physical methods, but the effect was still very limited, after all, the bones on his feet were broken, and there was no way to restore them, and the bones were fundamental, it was not restored, and other methods were naturally difficult to have an effect.

Just when Li Xiu sighed and retracted his gaze, he suddenly found that Li Shimin was also looking at Li Chengqian's limping figure, and his eyes also had a complicated look, which made Li Xiu stunned, and then when he looked closely, he found that Li Shimin had turned his head and was laughing with the eldest grandson Wuji, and there was no abnormality in his expression, which made Li Xiu wonder if he was wrong?

The printing office was originally in the imperial city, and Li Xiu and Li Shimin also rode horses, but Li Chengqian couldn't ride a horse after his feet were disabled, but he also took a special carriage, so after a while, the four of them came to the printing office.

At the moment, Li Xiu took the lead in dismounting, and then asked Li Shimin to enter the printing office, although the printing bureau now only has a set of copper movable type, but considering that there are many books that need to be printed in the future, the scale of the area is not small, and there are also many craftsmen who are transferred, although many people do not have the opportunity to contact real printing, but they can learn on the side, and Li Xiu also arranges the rotation of craftsmen, so that everyone can have practical experience.

After entering the printing room, Li Shimin was also very interested in various printing tools, Li Xiu also took the opportunity to introduce it, and by the way, he also asked some craftsmen for credit, such as the craftsman who proposed to change the wooden plate to a copper plate, and fixed the movable type with rosin and wax, which was praised by Li Xiu, and Li Shimin was also very generous, and immediately mentioned the level of the other party's craftsman, and also rewarded a lot of money, which made the rewarded craftsman also shout "Long live my emperor".

After the introduction, Li Xiu handed over the clan chronicle to the craftsman of typesetting, and the craftsman of typesetting arranged the movable type according to the content of the clan chronicle, and then handed it over to the steward for review, mainly to see if there were any typos or omissions, if there was, it was immediately necessary to return to change, if not, it would be handed over to the next craftsman, the craftsman mainly complicated to put the copper plate on the fire and roast, and wait until the rosin melted, the movable type was flattened and fixed, and finally there would be the printing craftsman brushing ink, covering paper and so on.

Li Xiu is well aware of the advantages of assembly line operations, so the steps of printing are very fine, and each step is responsible for a special craftsman, which can improve proficiency, speed up the work, thereby improving efficiency, and more importantly, each step has a special person responsible, so that if there is a problem in a certain step, you can directly find the craftsman who handles it, which makes each craftsman bear a certain responsibility, so that they dare not relax.

Although Li Xiu has let the craftsmen practice many times before, it may be the first real printing, plus there are Li Shimin and Changsun Wuji present, not to mention the craftsmen, and even the pressure on the stewards is also very great, so at the beginning, the printing process also made mistakes from time to time, especially the craftsmen of typesetting, and they returned to work several times in a row, so that the first edition was arranged, and then the first printing began.

A slightly yellowed mulberry paper is covered on the movable type that has been brushed with ink, and then the craftsman takes the brush and gently brushes it, and when the paper is removed, the first page of the clan history has been printed, and the handwriting is very clear, this is mainly because the ink is special, and bone glue is added to it, so that the ink will not disperse, and the ink used in general can not be used for printing.

The first sheet of the clan chronicle was printed, and the craftsman immediately presented it to Li Shimin, looking at the clear handwriting on the paper, Li Shimin was also greatly appreciated, and immediately promised that all the craftsmen of the printing office would be rewarded, which stimulated the motivation of the craftsmen even more, the first page of the clan chronicle was printed one after another, and the second page of the clan chronicle was also arranged, and immediately another craftsman took over and began to print, the entire printing office is like a machine running at full strength, and no one knows what kind of changes it will bring to Datang?
