I am very optimistic about you, and Li Shimin, the Ming Jun, pushed all the problems on Liu Yiyi. I read *book^fasting

The direct consequence of this sentence is that since then, there has been one more frequent visitor in Liufu, the Ministry of Industry, Tao Yande, like a piece of kraft candy, soft devil hard bubble, dead beggar Bailai, in the name of being ordered to do errands, as long as there is leisure, this old man Tao will bring some institutional structure of the specialty, to Liu Yi's side, the house.

Discussing the construction of hot air balloons is still secondary, and Lao Tao focused all his eyes on Liu Yiyi's unique mapping method.

Or that sentence, although people can't pull to the Ministry of Industry to work, but Liu Yifan's novel and clever drawing skills must be cleaned for him, after all, it is better to learn to fish than to get a fish, compared to the hot air balloon that can be made at any time, Tao Yande, who has a good knowledge and knowledge of the Ministry of Industry, still values Liu Yifan's design method that is simpler, more intuitive and clear than traditional patterns.

That is a pioneering act, this is Tao Yande's judgment in his heart in the face of Liu Yiyi's technique.

Compared with Li Shimin and those laymen who can only watch some lively, Tao Yande, a professional, can realize the role and significance of this new cartographic technique. is like a firewood knife and an axe, although they can both chop wood, but if you really chop a large piece of wood, or do a large project, Liu Yifan's new drawing skills are hundreds of times better than those firewood knives that can only be used to chop some fine wood.

If this kind of fine, intuitive, and clear composition method is used in palaces, bridge art, imperial tombs and so on, some of the scale is huge. And it is difficult to grasp the project, which is equivalent to planning on the drawings, avoiding or reducing some common problems and errors in the construction process.

How much money can I save? I always complain that I don't have any money left in my pocket. Tao Yande, who had been thinking about getting some funds from Li Shimin but couldn't, saw this mapping method as a treasure that could save money.

Therefore, Liu Yifan is now an indispensable treasure in the eyes of Tao Yande, the old scholar, and he saw Liu Yifan in plain life. Both old eyes were burning, and they couldn't wait to swallow him in one gulp.

"Master Tao, Master Tao, the student please," was chased by the old man, and in the living room of the Liu family's courtyard, Liu Yiyi, who was once again squeezed into the house by Tao Yande, bowed bitterly to this Tao Shangshu. I read the book & Zhai **** said: "It's not that students hide their secrets, cherish their brooms, and refuse to teach the adults of the Ministry of Industry this kind of drawing method, but that students really don't know where to teach, even if they really want to teach, they don't have a year and a half, and they want to make this kind of engineering design drawings neatly and without mistakes." Not a difficult word. ”

A word broke Tao Yande's thoughts that he had been implicit, Liu Yiyi didn't want to dodge with him anymore, if this matter was not resolved as soon as possible, God knows when this old man would stick, Liu Yiyi was fed up with the kind of behavior that even a person would follow him when he went to the thatched house, and since he was caught by Tao Yande again today, he simply made his words clear.

"A year and a half?" Old man Tao was stunned for a moment, and took this kind of words as Liu Yiyi's prevarication. Without being embarrassed, he said directly: "It's not too long, it's three or five years, as long as those few unsuccessful scholars can learn this kind of mapping method, the old man can afford to wait, and the virtuous nephew doesn't need to worry about the old man." ”

"Huh?"

Stunned for a moment, Liu Yiyi felt that he still underestimated the degree of this Shangshu master's relapse. Not at all expected. In the Tai Chi Temple, there are few words. Tao Yande, the secretary of the Ministry of Works, who looks honest and honest, has such a thick skin, and the two old men Su Bingren and Cheng Yanjin are really a fight.

Are all those old ministers in the court like this? Somewhat weakly, Liu Yiyi sighed in his heart.

"That being the case, the student has nothing to say," deliberately with a little reluctance, Liu Yiyi took out a book book from his arms in order to cope with today's situation, specially rushed out overnight, looked at it deeply, made a decisive look, stretched out to Tao Yande, and said: "This is the legacy of the master, divided into three parts: drawing geometry, projection, and three-dimensional space model, which are also interspersed with some basic mathematical algorithms. "Alas, how embarrassed is this old man, after all, this thing is left by your master, although the old man has a thick face, but it is not good to take away the beauty," the old man's two withered hands grabbed the book in Liu Yiyi's hand, his eyes were full of blue light, but his mouth was still very polite, and he looked embarrassed. \

"Master Tao doesn't need to mind," he let go of his hands playfully, watching Tao Yande take back the bookbook like a baby, Liu Yiyi spoke softly, and said some words that made Lao Tao feel a little awkward: "This is just a copy, it is a hand-copied by the student in the past few days, the student's words are thick, and it is rarely seen in people, and I hope that Master Tao will not be surprised." ”

"Oh, that's it, the old man is ashamed," there is a bit of regret, knowing that people don't want to, don't want to let themselves see the real book, to be able to take out this sub-book is already benevolent and righteous, some transgressions, Tao Yande is not good to ask for it again, after all, his goal of getting this book today has been achieved, besides, it seems that he doesn't know how to advance or retreat, and he really wants to attract the disgust of this Mr. Liu.

Raised his hand and looked at the treasure he had obtained so hard, just turned two pages, the old man Tao frowned deeply, the ugliness of the words in the book fell second, what made him a little worried and blushing was that he couldn't see the reason for the things on this book, he didn't understand.

Triangles, squares, and flat quadrilateral lines are easy to understand, but they are nothing more than some border frames, which are clear at a glance, but these two-dimensional, three-dimensional, x-axis, y-axis, z-axis, what are these things? And that central projection, parallel projection, how do you map it? What is the use of drawing?

A lot of fresh words, a few pairs of graphic structures that can't see what they are, and those more and more questions, make Tao Yande, the secretary of the Ministry of Industry, a little dizzy, but this also makes him more sure of the authenticity of this subbook, it turns out that what Liu Yifan said for a year and a half is not a lie. ^^^^

"What is written in this thing, but the virtuous nephew already knows it?" Two days ago, Tao Yande still screamed one by one, and the two old eyes glanced at Liu Yi here again with a millimeter.

"There are still thousands of miles away, but unfortunately the ancestor is no longer there, and everything is a student who groped for everything." The old man's ** had just picked up, and Liu Yiyi was busy filming him very tactfully, and he had never been a teacher, so why should he teach? In a word, he blocked what Tao Yande wanted to say again.

"Your master, you are really a master!" After playing a side game, seeing that Liu Yifan had no intention of being a teacher and taught in the Ministry of Engineering, Tao Yande was no longer reluctant, and casually exchanged a few words with Liu Yifan, said a few polite and useless words, and then got up and said goodbye, and returned Liufu Liu one by one.

"I don't think I'll come back, will I?" Taking the tea handed over by Chu Chuduan, Liu Yiyi let out a sigh and brought the tea bowl to his mouth and tasted it lightly.

"Lord Tao is also happy to see the hunt, not really that kind of unreasonable scoundrel." Slowly sat down beside her husband, Zhang Chuchu said softly, and while wearing a high hat for Liu Yiyi, he also said good things for Old Man Tao: "It was the husband's amazing talent that made Master Tao move his heart to close the book, just like back then, Lord Tao wanted to win over my father to his Ministry of Engineering." ”

Zhang Chuchu also had some impressions of this old man Tao, when Lao Zhang was pressed, he had reached out to help, and he wanted to pull Lao Zhang into the Ministry of Industry to work, but at that time, Lao Zhang was already a little cold about this officialdom and did not agree.

"Therefore, in the past few days, my husband has never been really angry, even today's gift of books is also intentional for my husband," Wen smiled and glanced at his daughter-in-law, Liu Yi sipped the tea, and said: "This Lord Tao Shangshu knows the way of advance and retreat very well, the law, the measure, and the grasp is very accurate, no wonder he can stay in the position of the Ministry of Industry for decades." ”

To tell the truth, for Tao Yande, the old man, Liu Yiyi still admires him, no matter whether it is in the Tang Dynasty or in the later era, there are not many officials who can be as dedicated to the public as him and corporal Lixian. Well, of course, it's rare to have a thick skin like him.

"People are upright and upright, this is the creation of Master Tao. However, can the Kong Ming lantern made by the husband really carry people to the nine heavens? Putting aside Old Man Tao, Zhang Chuchu looked at the sky outside the door with some fascination, and said to Liu Yiyi: "The concubine also wants to fly up to see and see Chang'an under the blue sky, what kind of check is it?" ”

"That's natural, but if you really want to take people into the air, you have to wait for a while, and now, there are still some dangers," for this kind of half-tone hot air balloon made by himself, Liu Yiyi also has no confidence in his heart, and he doesn't dare to let his daughter-in-law take risks, and the safety problem is still to wait for the skilled craftsmen in the Ministry of Industry to solve all of them.

"If the lady wants to go, she will drive for her husband in the future and take the lady to the sky to see it." Turning his head to look at Chu Chu, seeing the yearning on her face, Liu Yiyi whispered to her.

Moving to a house, decorating a house, rarely having time, and breaking for so long, Lao Liu sincerely apologizes to everyone
