Li Chengqian doesn't remember anyone who heard that a car is just a sofa and four wheels. It is precisely because of this that he had the idea of ​​building a car in Datang.

But it turns out that a car is not just one sofa and four wheels. It is a waste of about 50 million chunks of just one engine, not to mention that there are complex things like a gearbox that need to be studied.

So when he watched the wooden rack slowly moving in front of him at a speed of almost walking, he felt indescribable whether it was happy or sad.

But unlike him, the others in the workshop cheered after the wooden racks moved. This was the first time after the train and the tractor that a so-called car was moved with their personal strength.

When human beings were born, they were constantly exploring the unknown places around them, and human beings' understanding of the world continued to increase with the scope of activities.

Initially, humans could only move a few miles or dozens of miles around the camp, so people seemed ignorant. Later, they cultivated war horses, and the range of human activities increased a lot, and there was also war. But war was obviously not all after the increase in the range of human movement. Trade was born at the same time.

As the scope of human activities continues to expand, ethnic groups become tribes and tribes become countries. While humans are constantly protecting their own scope of activities, they are also cognizing the entire world and themselves.

Until the 21st century, human activities had expanded to the vast space, and their understanding of the entire world became increasingly profound, and human civilization also advanced to a level that the ancients could not imagine.

Li Chengqian sat in a corner of the factory area of ​​the Academy of Sciences, staring blankly at the wooden shelf in the distance moving back and forth. Some children from the researchers chased after the wooden shelf and ran around, climbing up, jumping down, and the corners of their mouths were slightly raised.

"Your Majesty, the car is completely fine. Do you want to try it?" At some point, Tang Shanshi had already gotten off the wooden rack and walked to Li Chengqian's side.

"I won't try it anymore. There are still many things missing in this thing. You have to keep working hard." Li Chengqian shook his head.

After a period of buffering, his interest in the wooden rack became much weaker. In later generations, high-speed railways could reach a speed of 300 kilometers per hour. After seeing that speed, the rhythm of the wooden racks not much faster than the ox cart can no longer make him excited.

Tang Shanshi seemed to have known that Li Chengqian would say this for a long time, and said with a wry smile: "Your Majesty, you can't let me rest for a few days. This so-called engine has been busy for many years, and I haven't even returned to take a look at my son."

"Don't tell me that these useless things are useful. I just asked you to hurry up, but I didn't let you huddle in the Academy of Sciences to do this." Li Chengqian laughed and scolded, then pointed to the wooden rack controlled by others in the distance and said, "This speed is too slow. Next I need you to build a gearbox, that is, a combination of different gears. When there are enough combinations, the speed of the car will be raised."

"Combination gear?" Tang Shanshi suddenly patted his head, looked at Li Chengqian with his head tilted, and said, "Gaoming, you're really good at this word, you're really smart! Why didn't I think of this? I was thinking about whether to continue to increase the engine cylinder or engine power. Now, after you say this, the gearbox is indeed a good way to solve the problem."

"Haha, there will always be more solutions than problems, right?" Li Chengqian stood up and stood side by side with Tang Shanzheng. After a moment, he realized: "By the way, you guy didn't call me smart one day. What's going on today? You're so brave?"

"Uh..." Tang Shanshi was stunned, then he remembered what he said, and hurriedly bowed to apologize: "Your Majesty forgive me, I just neglected me..."

Before Tang Shanshi could finish his words, Li Chengqian interrupted him with a shady face: "Get out, don't you give me this trick. Do you believe it or not, I will really punish you for your great disrespect?"

"Hehe, Your Majesty is wise!" Tang Shanshi stopped when he saw it, and the thirty-year-old man smiled and flattered Li Chengqian.

Fortunately, Li Chengqian was in a good mood during this period. After glanced at him, he didn't say anything about him. He just continued to say: "You just said that you should not stop research on increasing the number of engine cylinders. In addition, the research work of the materials department should not be stopped. Pay attention to the engine's cooling problem. The most important thing is the brake system. You should seize the time. Don't stop when the car moves and can't stop, which will make a big joke."

Tang Shanshi nodded while listening, secretly wrote down everything Li Chengqian said for slow study in the future.

Next, the two talked about other issues in the Academy of Sciences, such as rubber technology, materials science, radio, etc.

It was not until late that the researchers had enough of the car made of wooden shelves that Li Chengqian packed up and prepared to return to the palace.

When he was about to reach the gate of the Academy of Sciences, he seemed to suddenly remember something, and turned to Tang Shanshi and said, "In that car just now, you reduced the shelf and added a shell outside to make it beautiful, and I'm useful."

"Ah? Didn't this mean it's just a semi-finished product?" Tang Shanshi couldn't react a little.

"Don't worry about half-finished products. In short, there are two more chairs inside, and all the glass is installed by the way. Remember to get the brake stuff done." Li Chengqian was too lazy to explain to Tang Shanshi what he wanted to do with that train, so he left the Academy of Sciences and boarded the train back to Chang'an.

...

Ten days later, in the Daming Palace, a car with a dark color and style close to the later generations appeared at the entrance of the palace.

The imperial guard guarding the palace gate looked at His Majesty the Emperor in the driver's seat, holding the steering wheel with one hand, and putting a cigarette in his other hand on the window, driving the car in a very stylish posture.

Li Chengqian had seen the gazes of those imperial guards along the way and had long since ignored them. After the car entered the Daming Palace, facing more astonished gazes, he continued to move forward calmly.

At this time, the Imperial Garden of Daming Palace, His Majesty Li Er, was holding a banquet. A group of old guys were drinking and drinking. It was not until Li Chengqian stopped the car and jumped out of the car that the old guys all looked at the dark-colored car.
