Putting down the notes in his hand, Yuan Ling breathed a long sigh, and a box of information drawings was chewed bit by bit with the help of Liu Qin'er.

This process took a full nine days.

Yuan Ling almost never left the house and studied the information about the trolley left by He Chou.

This spirit of specializing in research made Liu Qiner, who was accompanying him, wonder many times whether the person in front of him was the King of Shang of the Tang Dynasty he knew.

But no matter how you look at it, there is no deviation in your appearance. Even the subtle characteristics prove that he is the Li Yuanai who rescued him from the sea of ​​fire.

However, the way of speaking in temperament and daily behavior are very different from before, and it is difficult to connect two people together.

"Thanks for your hard work!"

Yuan Ling stretched his waist very much. Liu Qin'er was the hardest one these days.

I can see this taste with relish, understand, and see it. But she is different. The boring day after day translation and explanation are not something that ordinary people can bear, but she has no resentment.

Liu Qin'er stepped forward intimately, rubbed Yuan Ling's shoulders, and said, "What is this compared to the Yeting Palace and Taichang Temple? His Highness has been following His Highness personally for so many years, but he still doesn't know that His Highness is interested in this car."

Yuan Ling felt that he was Li Yuanai, not Li Yuanai. It would be too difficult to learn Li Yuanai, and he could not learn it even if he had to learn it.

I simply continued this near-death accident and changed my temperament.

Li Yuanai is not popular and will not have too many problems. The key lies in the few people around her.

Liu Qin'er is one of them. As long as you fool her, everyone else will be fine.

"That's not the trouble of the late emperor?"

Yuan Ling had already prepared his words and said with a bit of reminiscence: "The Emperor of the First Spoiled me so much that he just wanted to arrange everything for me clearly. Find the best gentleman for me and arrange the best environment for me. I knew he was for my own good, but he never cared about my thoughts and feelings. At that time, he was young and unwilling to learn if he didn't like it. The more he forced me, the more he was rebellious, and gradually he couldn't change it. He walked around the road to the underworld and figured it out. Life is his own, and he couldn't live as much as his father expected. It's better to do what he liked..." He said, pointing to the notes on the table and said, "This is what I like."

How could Liu Qin'er tell the difference clearly? Besides, as the singer in the mansion, she seems to be glorious, and if she is not careful, she may give it to the business. She is not even as good as a maid, so how dare she investigate it carefully?

Seeing that Liu Qiner agreed with this statement, Yuan Ling continued: "This He Chou is worthy of being a comparable to Yuwen Kai. His bold idea is very combined with reality. He completed the rough car by thinking about it alone. It was just that there was a big problem with the power, which resulted in the effect not as good as the old-style keel water wheel. As for He Zhi, he did not have the talent in this area and did not expect it to be in the idea. However, years of research have made some gains. With their experience in hand, the tumble car is just around the corner."

He knows the appearance of the cylindrical car and also knows the working principle of the cylindrical car. The difference is the details and experience.

Now that the knowledge he has is combined with the notes left by He Chou and He Jian, everything is ready.

"You go down and rest first!"

Yuan Ling planned to integrate everything, but Liu Qin'er had no need to stay.

Liu Qin'er bowed and said, "Your Highness should also rest early, don't let your body break."

Yuan Ling waved his hand indifferently and said nothing.

This situation is common in later generations. When writing papers in the early years, when designing resorts, it is common for them to stay up late to work and find information.

Yuan Ling spent another three days to sort out the knowledge in his mind. Especially the wheel axle, he wrote very carefully, and the overall structure of the cylinder car, using mechanical formulas to balance the size and proportions of the cylinder car to pursue maximum kinetic energy.

Architectural design is a job that pursues perfection.

Yuan Ling also developed a character who pursues perfection and is not careless at all.

The only thing that caused him a headache during the whole process was the words.

In his previous life, he did not study brushes deeply. Li Yuanai's own calligraphy was very average, which was better than him, who was not good at writing brushes, and his writing was also crooked.

This whole article, which is similar to a paper, is presented in such extremely ugly words, and even Yuanling can't bear to look at it.

In the end, I have to ask Liu Qiner to reprint it. After all, this thing is not wrong at all.

Next, Yuan Ling found a famous craftsman in Chang'an and invited them to the mansion to build a trolley with a high commission.

As the most prosperous city of this era, Chang'an's biggest advantage is its emergence of talents and complete materials.

Most of the materials you need can be bought in the western market, and the recruited old craftsmen are also first-class.

After half a month of running-in, the first barrel car was officially completed in the backyard of Da'an Palace.

Seeing the huge trunk turning slowly and the flowing water was introduced into the pond in the other courtyard along the wooden trough, Yuan Ling's face was excited and a little excited. An object that was beyond the age was born in his hands.

The ascended carpenters around were even more stunned.

The leader, Qi Xiang, is already 60 years old and is even more excited. He wants to cheer and vent, but he can't even speak a word. His face is flushed, his hands are trembling, and he stammers for a while and said stammeringly: "Success, is it successful?"

He has the highest woodworking skills and is also the main person in charge of manufacturing wheel axle technology.

This old carpenter made a great contribution to this car.

He was so excited that he was crying.

"Yes!" Yuan Ling turned around, looked at the carpenters, and said seriously: "We succeeded!"

Cheers suddenly rose.

Qi Xiang was stunned for a while and bowed respectfully to Yuanling.

This old carpenter didn't believe that the trolley could be successful from the beginning, because He Chou tried it when he was in charge of the prison, but in the end he failed.

The reason for coming is simply for something very realistic... money.

Qi Xiang has been a carpenter all his life, with extraordinary skills, a stubborn and stinky temper, and is not likable. Because of this, he is unable to make ends meet and has left nothing for future generations.

Now, one foot has stepped into the coffin, and there are many children behind me. Thinking of the past, I feel that I have lived for a lifetime and have not left anything for my future generations, and I feel very regretful.

I happened to meet Yuan Ling hiring a carpenter at a high price.

In the past, Qi Xiangli ignored him based on the reputation of Shang King Li Yuanai, but now he has lost face and is playing around with the Shang King.

I never expected it to be successful.

Most of the other craftsmen have this mentality, followed one after another, with a little apology on their faces.

They all know what the success of this car means. Not only can they leave a name in history, but they can also leave a heavy mark in their career as a craftsman.
