He Yan's enthusiasm seems to have been a little too much, and Yuan Yun is very uncomfortable, this guy has been bowing down since they met in the morning, and he kept flattering with a pious smile. Pen ~ fun ~ pavilion www.biquge.info

As long as Yuan Yun raised his hand, He Yan could serve tea, and as soon as Yuan Yun raised his hand again, He Yan could send a brush that had absorbed ink, and every time he sent something, it was really what Yuan Yun wanted. The most unreliable thing is that when Yuan Yun was writing on the bamboo slips, He Yan actually praised what dragons and phoenixes danced, and what was strong and powerful, it was really pure.

At the age of seventeen or eighteen, wearing a brocade dress, plus all kinds of colorful accessories, changing so many things for others to wear, it must make people feel like an upstart, but He Yan can't, he looks like a girl's beautiful face, coupled with his slender figure, which makes Yuan Yun feel that it is a pity that this guy didn't go to Thailand.

When he was thinking about it, He Yan's beautiful face moved over again, and the distance of the three fists was about to be pasted, Yuan Yun tilted his head back defensively, and then carefully looked at this face again, white, very white, really white, an old man looks so white, I don't know if there is something wrong with God?

"Brother He, we are also meeting for the first time, why do I have the illusion that you seem to think that we are old friends." As he spoke, Yuan Yun raised his feet, left the seat in his study, and then opened the door, just standing at the door and looking at He Yan.

He Yan followed with a smile, and then replied with a smile: "I had a dream last night, I dreamed that an immortal came to my side, and I was instructed by Aunt Ding to come over to see Brother Yun this morning, so naturally I should be like an old friend." ”

"You shouldn't mean that Zhou Gongtuo gave you a dream, right?" Yuan Yun continued with a little teasing.

"Yes, yes, that's what I thought, it must be that Duke Zhou knows that I want to meet Brother Yun, so last night's dream with me must be like this." He Yan seemed to answer very seriously.

Wait, Yuan Yun secretly sighed in his heart, as if he had found the reason why He Yan was so close to him, this He Yan has been obsessed with metaphysics all his life, and he is nominally a disciple of the great immortal Zuo Ci, and this guy in front of him sees himself is equivalent to a hungry dog seeing meat buns.

Damn it! Lao Tzu is the meat bun.

"By the way, Brother Yun, Aunt Ding said let me help you, what is it to help?" He Yan finally said that he was on the right path.

Yuan Yun didn't answer, walked back into the study, and then took out a sheepskin from the bookcase, and unfolded it to reveal an engineering pattern drawn on the sheepskin. It's not that there is no paper in this era, but it's ridiculously expensive, the same area of paper is basically more expensive than sheepskin, and the density of the paper invented by Cai Lun is not enough to draw detailed lines on it, and finally Yuan Yun still chose sheepskin.

And in order to draw this sheepskin pattern, Yuan Yun did not work hard, not because the drawing itself is troublesome, but because it took him a lot of energy to make the charcoal for drawing, and the brush of this era cannot meet the delicate structure of drawing, let alone let you draw a straight line against the T-shaped ruler.

After the pattern was taken out, Yuan Yuncai said: "You are engaged in being a master craftsman, so naturally you can make this thing in the official's workshop, I will pay for all the materials, and after the finished product is sold, I will give 10% of the profit to the official's workshop, and also give Brother He Yan 10% of the profit as a benefit." ”

Although He Yan is obsessed with metaphysics, but he has been in the Ministry of Industry for a long time, he is still very concerned about the construction, he is a smart person, so he learns everything quickly, as soon as the sheepskin pattern in front of him unfolds, he immediately gasped, densely drawn lines, and annotated instructions, covered with all corners of the sheepskin pattern, after a careful look for a while, but he was completely uninterested in the profit of Yicheng, and it was estimated that he felt that he would not make much money by relying on the things on the map.

When Yuan Yun drew the drawing, he had already converted many units into the measurements of this era, although there were still many things that could not be represented, and they had also made a general explanation, and after switching back to writing with charcoal, the handwriting he left on the pattern looked much better and easier to see clearly.

He Yan watched it for half an hour, during which he didn't say a word of nonsense, his eyes were full of those connected structural lines, and when he saw something he didn't understand, he would look at the text explanation that Yuan Yun left on the side, and just figured out the principle of driving this car.

Looking at He Yan's suffocating appearance, Yuan Yun only felt funny in his heart, this is just a design drawing with simple shock absorption, the steelmaking furnace that he really put his heart into designing recently is the point, if you don't find some old craftsmen and then personally participate in it, it will definitely not be realized, so I don't plan to show it to He Yan at this moment.

Yuan Yun is also helpless, although the production level of this era is low, but there have been several steelmaking methods, but these ancient steelmaking methods are definitely not comparable to the modern converter steelmaking method, and in order to ensure higher quality, but also after the material is baked, and then use the 100-fold steel refining method to build it by hand, in order to be qualified. And for the key blower part of this furnace, Yuan Yun can only use air bags made of cowhide instead of rubber air bags, which will definitely affect the quality of steel. But even so, I believe that when the steel comes out, it will be the best material in this era, and it will inevitably become a new immortal artifact after the finished product.

"Although it is difficult to make this car, I believe that the craftsmen of the workshop should be able to handle it, after all, most places are no different from the old cars, I just don't understand what is the use of this thing? Cars and cars, those big families who can afford to use them are basically made in their own homes, but they will not find others to do the OEM, how can this be sold? He Yan finally asked a question.

Yuan Yun smiled mysteriously, and then shook his head and replied: "Who knows, when you look at others are magnificent and comfortable, many ideas will change, and once you have the idea of comparison, that is, only buy expensive ones, not suitable ones." ”

He Yan was stunned and puzzled: "Elegant and comfortable?" Could it be that the car with the wheel axle changed is not the car of the fairy family? ”

Yuan Yun remained mysterious, continued to shake his head and was reluctant to uncover the mystery, and He Yan turned into a face holding stool again, but in an instant, He Yan suddenly had a flash of inspiration, and he was already sure in his heart that this must be a car commonly used by immortals, otherwise how could it be sold so expensive?

At this time, He Yan immediately became happy, and made up his mind in his heart, when he returned to the workshop, he would personally supervise the construction, this is an immortal thing, I have only heard of it in legends, how can it be easily handed over to others? And at the same time, it was also secretly decided that the craftsman who made this immortal car must give an order to make them sealed.

In this way, He Yan studied the pattern and asked for some details, and stayed at the Yuan family until the evening, and after confirming that Yuan Yun would not discuss the metaphysics of the immortal family with him, he finally reluctantly left the Yuan family's mansion with the car driving pattern.

After sending He Yan away, another 'old friend' came to the Yuan family's mansion, Wu Yong, the official of the East City Gate.
