After returning to the palace, Li Yuan hid the blood-stained silver hairpin in the room to see if there were any clues in the future. Although the secret planning of the water case was done by those families with bad intentions, it can be ..... Who knows if those forces of the old Sui are involved in it, but that Concubine Li is...... The surname is Xiao!

And the family surnamed Xiao is only in the Lanling Xiao family in the south of the Yangtze River. (The Yongjia Rebellion migrated to Jiangnan)

"This matter can't be alarmed, someone sent someone to monitor Queen Xiao and Xiao Yu, neither of them had any abnormal behavior, if the assassination of Empress Changsun can still be understood, as soon as the queen's seat is vacant, then Concubine Yang will have a chance to ascend to the throne, and when the time comes, Ke'er will become a concubine, and she will naturally have the advantage of competing for the throne, but ...... The target is Li Zhi, except for a certain one, Li Zhi's existence can be described as transparent, after all, only I know that he is the future emperor. Li Yuan said secretly in his heart.

The Nine Emperor Princes Li Zhi does look very transparent, not only is he young, but he also has two elder brothers on his head, the crown prince Chengqian and the king of Wei Li Tai, these two are not ordinary people.

"Forget it, forget it, let's prepare a congratulatory gift for Cheng Qian." He shook his head.

When he returned to the palace, it was already afternoon, and soon it was dusk, and the emperor returned to Da'an Palace to sleep well, and when he woke up, it was almost noon.

The Emperor Taishang is different from the emperor, he doesn't need to deal with the government every day, he is like an idle person every day, and he can sleep as long as he wants.

The general prison is located in Gyeongyeonfang, next to the west side of the palace, in charge of the palace building, the production of gold and jade beads and rhino elephant treasure utensils, the embroidery of leno and various strange utensils, the official office made of countless skilled craftsmen, up to the emperor's crown, down to the soldiers' swords are made from inside.

After Li Yuan and Li Chengqian selected a few gold artifacts at Liu Ji Gold and Silver Shop yesterday, he thought of something to give to Li Chengqian, which was enough to suppress the artifact of the Li Tai Literature Museum, that is, movable type printing.

Movable type printing could not be invented until the Song Dynasty, of course, what the Emperor Taishang wanted to give Li Chengqian was not only movable type printing, but also the lead movable type printing press made by Gutenberg in Germany, although the structure was slightly complicated, but the craftsmen of the Tang Dynasty could still completely copy it.

That's right, if you want to suppress the literature museum of Li Tai, the king of Wei, then there is only one way, and that is to master the tongue of the Tang Dynasty, that is, the newspaper, and the newspaper conducts the media. However, if you want to use the newspaper media, you must solve the problem of typesetting and printing, otherwise you will not be able to meet the demand for mass printing, and then the newspaper will be reduced to the upper class of newspapers, in which case it is better not to invent movable type printing.......

"The ministers see the Emperor Taishang, dare to ask the Emperor Taishang why he is here?" The young eunuch Wang, who will be the prisoner, owes his life.

Although the general is involved in a wide range of fields, it is always provided to the royal family, although Wang Shaojian was a little surprised to see Li Yuan, but it was still within the acceptable range in his heart.

Before coming to the general as a prisoner, Li Yuan inquired about the composition of the general as a prisoner, so he went straight to the point and said: "A certain group of craftsmen who make engravings are needed." ”

"The craftsman of the engraving ......" Young Eunuch Wang was surprised for a while, but he still nodded and ordered to find the craftsman.

The supervisor is divided into various departments such as the Left School Office, the Right School Office, the Middle School Office, and the Zhen Office, each department is in charge of different affairs, if you want to find an engraving craftsman, you need to look for the Middle School Office.

After drinking a few sips of tea in the main house where the prisoner would be served, Young Eunuch Wang brought the carving craftsmen, there were three people, one old and two middle-aged.

"Your Majesty, these three people are the craftsmen of engraving and printing." Young Eunuch Wang paused and introduced: "This is their roster, I bother the Emperor Tai to read it personally, and Weichen will go down first." ”

When the young eunuch went down, the three craftsmen looked panicked, and they all bowed their heads and trembled at the lamb to be slaughtered.

Although the craftsmen of the Tang Dynasty are not as low as those of the Ming and Qing dynasties, they are really not very high. In addition, what they saw was the Emperor Taishang, the emperor, the respect of a country, how could they not be afraid in their hearts......

Li Yuan put down the tea bowl in his hand, flipped through the roster, looked at the three of them carefully, and saw that they looked somewhat similar, so he asked, "Are you father and son?"

The three of them glanced at each other, their faces were uneasy, and the old one replied first: "Emperor Hui, the old man's name is Niu Daren, he is a widower, he has no children under his knees, these two are my nephews, and they have learned this craft to make a living." ”

"That's good..."Li Yuan nodded, took out a printed copy of the "Diamond Sutra" and handed it to Niu Daren, and asked, "This "Diamond Sutra" is engraved and printed by you?" ”

The invention of engraving printing in the Tang Dynasty, to the middle and late years was widely used, the Emperor Taishang thought that there should be no Zhenguan period, but he did not expect to find this printed Buddhist scripture on the dresser of the painting screen.

Although the regular script of the ancients is perfect, and the writing is as true as the printed one, if you really look at it carefully, you can still see some differences, after all...... Who writes and draws neat frames on the outside......

"We printed it." Niu Daren said.

Just when the Emperor Taishang didn't care, Niu Daren said something that moved him, "The plate material for engraving printing is generally made of fine and solid wood, such as jujube wood, pear wood, etc. Then the wood is sawn into pieces of planks, the words to be printed are written on thin paper, and then pasted on the boards, and then according to the strokes of each word, the strokes of each word are carved into yang characters one by one, so that the strokes of each word are protruding on the board. Once the board is carved, the book can be printed.

At that time, the villain's father was rewarded with 20 yuan by the prison for this handiwork......."

"Your father invented block printing?" Li Yuan was suddenly surprised, most of the inventions in ancient times were the crystallization of working people, but he really didn't know which working people it was.

The people at the bottom invented this kind of cross-era invention, and they were rewarded with a maximum of 20 yuan, but Cai Lun of the Eastern Han Dynasty was rewarded for transforming papermaking.......

"What's your father's name? A certain is about to set up an inscription of inventors of various eras in the medical school....." Li Yuan said.

If you want the ancient people to be willing to create and dare to invent, you need to elevate the status of inventors, otherwise it will be all up to luck, then the Tang Dynasty will slowly implement industrialization and get the Year of the Monkey. In addition, although the sub-department of the medical school is to cultivate science and engineering talents, it cannot chill their hearts and say that they are the same as craftsmen..... For so long, science and engineering students who are only supported by interest will slowly lose their hearts, after all, this world still has a future in liberal arts.

"This ...... This ......" Niu Daren was instantly excited and couldn't say anything.

Erect a monument!

Erect a monument! That's a monument!

He can also set up a tablet for his father in front of his house, but whoever can read it, it will become a handful of loess in a thousand years, but the inscription of the Emperor Taishang is different, and it is recognized by the emperor, which is a disguised name in history。。。。。

If it can be passed down to future generations, then the forest of steles in Xi'an may also add a legendary inscription with the words of the present world......
