When Li Yuanying saw Li Shimin's expression, he realized that he had actually said it, and while revealing the same cute expression of Jinyang Xiaobaozi, he secretly rejoiced, fortunately, he didn't say that he was a big-eared thief!

"The vertical son is rude, and you will be punished for copying a thousand-character text ten times, and use thin muscles!" Li Shimin patted the top of Li Yuanying's head and said angrily. The majesty of the elder brother cannot be lost, although he said that he is a good brother of the Tang Dynasty...... That can't be said to be a nickname!

"Yui." Li Yuanying responded very obediently, "After I finish writing, I will ask Mr. Gongsun to send it to Luoyang." ”

Li Shimin nodded, looked at Yuan Tiangang, and asked softly: "Yuan Gong, has Xiao Shiyi accounted for the matter of Sanmenxia?" ”

It's not that he doesn't believe in Yuan Gong, but Xiao Ruoyuan's accounting ability is as outstanding as his face, if this person is not so narcissistic, he can go to the Ministry of Civil Affairs Ren Du Zhilang.

"Back to Your Majesty, it has been calculated." Yuan Tiangang bowed and said. "Ten zhang deeper than the original cleaning depth, Xiao Shiyi calculated that the capacity of the oil steam engine is three times that of the coal steam engine, but the cost of oil is much higher than that of the coal coal, and the steam engine needs to be improved to reduce loss or improve the utilization rate."

Not to mention, these words newly compiled by Xiao Shiyi are really appropriate...... I just don't know how many of them were compiled by King Teng?

Li Shimin didn't expect this kind of answer, the oil is better than coal, how can it sound so similar to the story in Sou Shenji? With some hesitation, he said, "Isn't that white light too extravagant and wasteful?" ”

"Back to Your Majesty, that's not going to happen." Liu Bu put down the paper in his hand and said with a salute. "The oil can also be separated several times, and the oil used for lighting the lamp is not suitable for fuel, and there are too many impurities, which will damage the steam engine."

He looked at Yuan Tiangang again and asked, "After the dredging of Sanmenxia, can you try a steam ship to transport more bamboos of all colors?" I need to experiment with several ratios to see which one is the best cost-effective, which one is more suitable for aluminum mold machines, and which one is more suitable for woodcut rubbing. ”

"This ......" Yuan Tiangang frowned slightly, there are patches of bamboo in Fuyang, and further south...... There are many bamboos in Lingnan Road, but it is quite difficult to transport them...... looked at Zhang Guo and asked. "What do you have to do?"

"It's just a bamboo for experiments, and a certain one can transport it." Zhang Guo shook his head with little white hair and sighed softly. "The bamboo in Yuhang County (Lin'an, Zhejiang) is not as good as Hongzhou (Yifeng, Chongyi, Jiangxi), the bamboo in Hongzhou is not as good as Chenzhou (Hunan Huitong, Taojiang), and the bamboo in Chenzhou is not as good as the bamboo in Jianzhou (Jian'ou, Fujian), Guizhou (Guilin, Guangxi) and Shunan."

Li Yuanying: "......"

Fortunately, there is a map of the afterlife. Compared with the current map, I really don't understand where they are talking about the specific location. However, the place names of each county today are really beautiful.

For example, Zaozhuang, which was ridiculed by later generations, is Lanling in the east, Fuyang in the south, Shuzhou in the west, and Tengguo of Qi in the north, which name has connotations than Zaozhuang.

Another example is Zhumadian, the hometown of Liang Zhu, the tomb of Li Si, the prime minister of Qin, the Fuxi painting hexagram pavilion and the iron-smelting site of the Warring States period, and the ancient city of Cai Guo in the Western Zhou Dynasty...... Yingchuan, Nanyang, Runan, which one is not better than Zhumadian?

Another example is Baotou and Hefei, which can be called Jiuyuan and Luyang, and I don't know how the names have become ...... fell off a cliff, and changed from a fairy to a second dog and a cuihua at the head of the village.

"Then we take some from each place, and after we're done, we decide where to make paper." Liu Bu said with some eagerness. "It's really not possible, you can let King Teng go to those places to serve, and we'll all go with you!"

Li Yuanying: "......"

Everyone else went to the land of anointing, and a certain went to Lingnan Road to work? Thank you so much, Liu Erlang! If you want to build Tengwang Pavilion, where did you come from Tengwang Pavilion without Tengwang Pavilion? Without the preface of King Teng's Pavilion, how can the children, adults and old friends of later generations visit King Teng's Pavilion for free?

Uh-uh, Teng Wang's Pavilion is gone...... The losses in Nanchang and Langzhong are too great, and they must follow the historical line!

"Your Majesty, Liu Bu doesn't understand the world, he talks nonsense, he doesn't know what he will say." Gongsun Bai hurriedly crossed his hands and said respectfully. It is impossible for King Teng to go to Hongzhou, so how can he go to Chenzhou, Jianzhou, Guizhou or Shunan?

"Mr. Gongsun doesn't need to explain, Liu Erlang's temperament has been understood by me these days." Li Shimin waved his hand and said with a smile. "Once the road is accessible, the problem is solved. The bamboo of Hongzhou can still be transported through the river and canal, and I will arrange for the governors of each state to be responsible for this matter, so as not to delay the use of paper. ”

As for the younger brother, he is still young, so there is no need to rush to do things, and he will be idle in the fief for a few years. He is more leisurely so that he has time to travel back and forth to Chang'an, and has time to do those things he likes.

To be honest, Li Shimin really worried a lot, it turned out that King Teng of the historical line didn't do anything serious except that he wouldn't embarrass himself.

"Thank you, brother!" Li Yuanying breathed a long sigh of relief, a certain Liangshan one hundred and eight beauties have not been collected yet, when I read the books of the ancient heroes, the happy forest was very fascinating. There is Pingkangli Nanqu in the west, and there is 800 miles of water in the east of the happy forest.

The talent of the peony, just for the sake of the maid, is too condescending. Qu Sanniang can be the deputy, after the trip to Jinzhou, she will know that Gaochang will not be in the country for a long time.

Xiao Ruoyuan put down the charcoal pen in his hand, looked at Li Yuanying and said, "King Teng, I need you to help me design a set of lenses, like a telescope, which can magnify the selected words to ensure that there will be no mistakes." ”

The words on the aluminum mold, if it is manually typeset, can be rechecked by a second person after the word selection. The organ selects the word differently, only the person who chooses the word can review, the word mold is too small and can not be too close, the width of the paper can not be too narrow, if it is too narrow, the staple line is too wasteful.

Li Yuanying put down the fast son, came to Xiao Ruoyuan's side, drew three times and six times the magnifying lens, and said with a smile: "As for which multiple is more appropriate, it needs to be calculated by Eleven Lang." Remember, don't miscommunicate your accounting methods and ruler diagrams. ”

Xiao Ruoyuan is different from Li Chunfeng, he has no sense of belonging to the court. Recently, Ken has been busy in the Tibetan Sword Hall, but his arithmetic skills are full, and he likes to study the current novelty equipment, and once he has studied them thoroughly, he may be wandering around with the glass book again.

Pei Qiqi said that Xiao Ruoyuan likes independent city walls, rooftops, boat heads or mountain tops the most, so that those who see him are amazed by the arrival of immortals, bow and worship, and then he flies away, like a shock.

Desire to perform.

Yuan Tiangang smiled and said, "King Teng rest assured, not only the Hidden Sword Hall, but also the ruler drawings and accounting records in all parts of Yunhe Mansion, even if they are circulated, they will not be able to understand them. Unless a certain person, Sun Gong, Gongsun Bai, and Wei Guizang helped the person who obtained the ruler plan at the same time. ”

Zhang Guo: "......"

Certain...... If you come late, after a while, you will naturally become your own person.

…… Li Yuanying is full of black question marks, what does it mean to get the help of the four of you at the same time, the Datang version of the encryption law?

……
