"This "Juvenile Saying" should be kept in mind in the future, to improve oneself must start from now, do not wait or rely on, the opportunity has been given to you, you hold the key to change your destiny in your hands, the elderly often think about the past, young people often think about the future, don't wait for the young man's head to be white, empty and sad! The young man does not work hard, and the boss is sad, I hope you will slowly understand these truths, and disperse! ”

Unconsciously, Zhen Qian felt that he was back on the sales podium, and even he was a little infected with his impassioned words, but seeing the ignorant children on the other side, only God knows how much effect these words have.

"Zhen Er......", as soon as the name came out, he couldn't help but want to laugh, and finally couldn't help but say: "During this time, you stay here, be responsible for the safety here, take these children to practice archery every day, if you have archery talent, you can take it with you for careful guidance, but the most important thing is to go around every day and learn about the terrain here, just in case, understand?" ”

Ajanano said awkwardly, "Got it,...... Father-in-law! ”

Being called a stepfather by someone older than himself was not only awkward for Ayana Ye, but even Zhen Qian himself felt a little unnatural, and hurriedly found a reason and said: "I'm going to Qin's house, stay there for a day, maybe I won't say goodbye to you, I'll leave it to you here!" ”

"Hmm!" Ajana Ye answered, and this time did not call his father-in-law out.

Zhen Qian turned around and saw Wang Qun standing in the distance, and stepped forward with a slight smile, "Let's go find Carpenter Lu!" ”

Lu carpenter's family lives in a separate bamboo building, and is very satisfied with the environment and conditions here, yesterday I heard that Zhen Qian is going to build two waterwheels here, and early in the morning I was ready to take my son to the neighborhood to look for wood, and when I saw Zhen Qian and Wang Qun coming over, they greeted him and said: "The construction of the waterwheel needs some iron and copper, Zhen Lang is not prepared in advance?" ”

"What iron and copper materials does Carpenter Lu need, write a list to the Wang family here, and they will help you prepare it!" Saying that, Zhen Qian took out a few pieces of paper from his arms, laid them directly on the stones on the side, and said to Carpenter Lu: "This is a drawing of a four-wheeled carriage I drew last night, and I used a two-wheeled carriage to transport things from outside, not to mention the small carrying capacity, and it is very dangerous to drive on this mountain road, so I reduced the width of the carriage, and the turning radius was reduced while increasing the flexibility, do you have any problems with Carpenter Lu?" ”

Since there were no cartographic tools, Zhen Qian drew a sketch of a four-wheeled carriage, the proportions are not bad, but it feels a bit of a sketch, plus the section drawings of several key parts, the whole sketch gives people a strange feeling.

"...... this?"

"The four-wheeled carriage has two more wheels than the usual carriage, and the weight of the whole vehicle is transmitted to the four wheels through the shock absorber, and the steering device is installed on the front wheel, so there will be no danger ......of falling off the cliff at the bend of the mountain road."

Zhen Qian also thought that he would shock Carpenter Lu by taking out the drawings of the four-wheeled carriage, but seeing Carpenter Lu's slightly thoughtful expression, he felt that things were not as simple as he thought.

Carpenter Lu asked in a stiff tone, "Zhen Lang, did you draw this drawing?" ”

"Is there something wrong?" did not get Carpenter Lu's praise, but his tone was a little strange, and Zhen Qian was unhappy in his heart.

"It's nothing, it's just strange that Zhen Lang can draw such a drawing", Carpenter Lu looked at Zhen Qian with something wrong in his eyes, and said slowly: "This four-wheeled carriage has been around since ancient times, but unfortunately the drawings have been lost, the shock absorber and steering gear design that Zhen Lang said is indeed ingenious, I don't know if Zhen Lang saw it from the lost scroll?" ”

Zhen Qian was a little confused now, Carpenter Lu actually knew about the four-wheeled carriage, in his impression, the four-wheeled carriage was rarely seen in ancient China, but the four-wheeled carriage was rampant in ancient Europe. Even in some murals and scrolls, such as the Qingming Shanghe picture, there are four-wheeled carriages, but they are just two-wheeled carriages with two added wheels, which can only travel back and forth, and it is difficult to turn at all, let alone shock absorbers.

Of course, there are many reasons for this, but there is one that cannot be avoided, that is, the low status of craftsmen, and the difficulty of people and carriages to be taken seriously.

Zhen Qian suddenly thought that maybe he had some misunderstanding of the four-wheeled carriage, and later generations also commented that the roads in ancient times were bumpy, and the four-wheeled carriage was not necessarily more convenient than the two-wheeled carriage, coupled with the stagnation of technology, there were many good things that had been lost, and the real reason was hard to say.

"But what's the difficulty?"

Carpenter Lu shook his head, nodded again, and said, "It is not difficult to make a four-wheeled carriage, but has Zhen Lang considered the price of the four-wheeled carriage and future maintenance?" ”

Zhen Qian naturally didn't think about this, "Carpenter Lu, please?" ”

Carpenter Lu looked at the drawings of the four-wheeled carriage and said: "The four-wheeled carriage painted by Zhen Lang here seems to be simple and small, but it is actually very complicated, especially the shock absorber and steering gear that Zhen Lang said, which is the key part of the four-wheeled carriage, if it is really manufactured, the price is probably three times that of an ordinary two-wheeled carriage, Zhen Lang really plans to build such a four-wheeled carriage?" ”

If he didn't know the history of the development of the carriage, listening to what Carpenter Lu said, Zhen Qian was really ready to dispel the idea of building a four-wheeled carriage.

Four-wheeled carriages are made with three times the price of two-wheeled carriages, and two-wheeled carriages are not only simple in results and easy to maintain, but also can be pulled by manpower due to the lack of horses, but not vice versa, which is the real reason why four-wheeled carriages cannot be popular.

It's a pity that Zhen Qian knows the advantages of the four-wheeled carriage, the speed and load capacity are better than the two-wheeled carriage, and it is driving on a mountain road with many curves, just look at the experience of coming to the Qin family twice, you can know that a two-wheeled carriage can carry up to five or six hundred catties, and a bunch of people need to pull forward and push around, and only in ancient times when the labor cost is very low, and the weight of the four-wheeled carriage is four or five times that of the two-wheeled carriage, and in the future, it is enough to have two or three such four-wheeled carriages for transportation between the Qin family and Zhending, after all, the fewer people who know about it, the better.

None of the problems that can be solved with money are problems!

Hearing that Carpenter Lu talked about the shortcomings of the four-wheeled carriage and reminded himself of the problem of cost and price, Zhen Qian knew that it was not easy to manufacture a four-wheeled carriage, but he still said resolutely: "Don't care about the price, Carpenter Lu just needs to tell me if I can make it?" ”

Carpenter Lu showed a smile and said: "Since Zhen Lang insists, there is naturally no problem with the manufacture of this four-wheeled carriage, but I want to remind Zhen Lang that driving a four-wheeled carriage is different from a two-wheeled carriage, and it is best for this driver to consider it in advance?" ”

Seeing Carpenter Lu's confident appearance, Zhen Qianleng paused, thinking that Carpenter Lu would shirk it, or put forward some harsh conditions, but he didn't expect to agree to it, and he really underestimated this Carpenter Lu.

This first confrontation ended in Zhen Qian's defeat, and the drawings of the four-wheeled carriage that he had stayed up all night only surprised Carpenter Lu for a moment, and the shock absorbers and bogies did not stump him, although it was impossible to determine whether Carpenter Lu had seen similar devices before, but it was certain that these were not too difficult for him.

"I also hope to see the prototype of the first four-wheeled carriage in a month, and now come with me to the Qin family, there may be something in the Qin family that needs your help?"

The three of them came to Qin Hao's bamboo building together, and Qin Hao, who was smiling, immediately invited his own weaver and carpenter over, and said straight to the point: "This is Zhen Lang, a distinguished guest of the Qin family, he has some things that the two of you need to do, this is also the Qin family's business, his words are what I mean......."

Zhen Qian looked up at the two craftsmen who were made Master Yan and Master He by Qin Hao, and saw that one of them was around forty years old, and the other was over fifty, the two looked at themselves with a serious face, with a trace of doubt and incomprehension in their eyes, but they didn't ask anything, obviously they already knew something in advance, but seeing Zhen Qian so young, they were a little curious about why they could get Qin Hao's attention.

Zhen Qian didn't say much, and said directly: "Master Yan is a weaving craftsman, I won't say anything politely, I want to know why I'm here, there is a bamboo sea around the Qin family, it's a pity to waste it, I want Master Yan to help me make some supplies, here are some drawings I made, Master Yan take a look at it first, if there is anything you don't understand, please ask?" ”

Master Yan stretched out a pair of hands full of wounds and took the drawings in Zhen Gan's hand, Master He and Carpenter Lu on the side also came over curiously, and looked at Zhen Qian with different expressions after a glance, Carpenter Lu nodded slightly, touched the beard under his chin, and blinked in his mouth, not knowing what he was talking about? Carpenter He was at a loss, with dim eyes open, trying his best to meditate.

The more Master Yan looked at it, the more excited he became, and his body couldn't help but stand up, opening his mouth and saying in a trembling voice: "This is all Zhen Lang came up with?" ”

"These are just very common things, I'm afraid it's a little difficult to process, I have some simple tools here, I need Master He's help", he took out a few pieces of paper and handed them to Master He, "Master Yan makes bamboo supplies, the manual is too slow, so I designed some tools to improve the processing speed, Master He to see if there is a problem?" ”

Qin Hao on the side didn't know what a few were talking about, so he hurriedly came up, and saw several names written on the paper: bamboo mats, bamboo chairs, bamboo plates, bamboo baskets, etc., all related to bamboo, but they were obviously a little different from the bamboo products he had seen, and they looked more exquisite, so he couldn't help but ask: "Zhen Lang, why are these bamboo mats all made of small squares, and this bamboo chair, it seems that every style is very strange, can these things be sold?" ”

Zhen Qian just wanted to answer, but the carpenter Lu, who was looking at the drawings, suddenly said: "Zhen Lang's ideas are indeed a bit unbelievable, but don't worry about not being able to sell them, if they are made, I am afraid they will become items that the rich are vying to buy, but I am afraid that the difficulty of processing these things is not low, I don't know how much can be made in a year?" ”
