Datang first village

[Dafeng today, thank you for your long-term support]

What is the origin of human civilization?

Li Yuanxing was holding a book in his hand. The book was selected for him by Li Lanshan. It was a series of books about the development of primitive civilization.

Sitting on the soft chair, gently closed the book.When Li Yuanxing reached for the teacup, a cup of hot tea had just been poured, and Ling Ye carefully handed the teacup to Li Yuanxing's hand.

Li Yuanxing did not have a personal maid. The so-called Twelve Gold Hairpins in the Qin Palace were more of the astonishing number of maids, maids, servants, and workers who managed the entire Qin Palace.

When they saw that Li Yuanxing was doing all the dressing and washing by himself, the Princesses of Qin generously arranged their personal maids beside Li Yuanxing. Cui Yanyan lived in Li Yuanxing's room during this period, so naturally they took this opportunity to send a maid Give it to Cui Yanyan's personal maid.

After taking the teacup, Li Yuanxing was originally accustomed to say thank you.

But I held back my words, a word of thanks might really scare this underage girl.

Li Yuanxing nodded slightly, just this small gesture made Ling Ye happy.

After taking a sip of tea, there is no need to put the teacup back on the table, only with this action, Ling Ye will take the teacup.

He reached out and tapped the tablet computer on the table, the screen was changing continuously, and Li Yuanxing was observing the progress of the three groups.

Tiangongfang was established for research.It will not be pure carpentry, nor can it be any single project, but a mixture of multiple projects. It is impossible to complete anything with one project.

"Gao Ming!" The screen on Li Yuanxing's tablet stopped.

Because Li Yuanxing was attracted by something that can be regarded as a small toy in modern times. It is a theoretical model made for design. It is exactly the same as the small tricycle that children ride in the 80s. The position of the pedal design is on the front wheel. Step on the front wheel and the car will go forward.

"Come on, call Li Yin!" Li Yuanxing ordered softly.

Li Yin, the prince, was about to be crowned King of Liang when he was just seven years old. The official ceremony has not yet been carried out, but the imperial decree has been officially filed in Tianying Pavilion. This is a prince.

Calculated to be at the same level as Li Yuanxing, one word king.

Of course, Liang cannot be compared with Qin, whether it is meaning or power, there is a difference between heaven and earth.

Soon, Li Yin was called over, and when he saw Li Yuanxing, he quickly bowed and said, "Uncle Wu Huang called his nephew, what orders do you have!"

"You look very well-behaved, but the emperor's wife has a headache for you. The game they competed in is not suitable for you. This king asks you to do another thing. You do it with your heart, learn it with your heart, and wait until you are 15 years old." When the time comes, Brother Huang will grab some foreign princesses for you and bring them back, what do you say?"

Li Yuanxing is like a wolf grandmother, tempting a full belly of bad water, but in fact he is still very simple Li Yin.

Sure enough, as soon as Li Yuanxing finished speaking, Li Yin shouted excitedly: "Uncle Wuhuang means what he says, and the Silla maidservants in Uncle Wuhuang's mansion are said to be the most beautiful in Chang'an."

"Very well, Princess Silla or something, that's not a problem!" When Li Yuanxing spoke, several guards' faces were twitching. They wanted to laugh, but they didn't dare.Ling Ye smiled boldly.

If someone dared to laugh in another place, Li Yin would dare to pick up things and throw them at them.

But this is Qin Wangzhuang, he doesn't have the guts!

Li Yuanxing's face darkened: "If you can't do well, what should you do?"

Li Yin slowly lowered his head and bit his lip.Li Yuanxing was not in a hurry, and continued to watch the progress of the workshop.

After waiting for a full quarter of an hour, Li Yin clenched his fist hard: "If you don't do well, you will be beaten and punished!" Li Yin's determination is really not small. For him, this kind of determination is definitely no less than a big one. Sergeant Tang was going to fight the enemy army to the death, and Li Yin knew that even the prince Li Chengqian dared to hit a bamboo board.

Li Chengqian crawled on the bed, his bloody butt shocked everyone.

Li Yin said that he was not afraid of being fake.

"Come with me!" Li Yuanxing stood up and walked out, Li Yin quickly followed behind.

At this time, in the courtyard of the Staff Council, Li Chengqian had already copied [-] words while writing and reading, and everyone was resting.

Li Ke came to Li Chengqian's side and asked in a low voice, "I won't make Uncle Wu Huang angry!" Li Ke was actually very worried, he knew who his younger brother was.

Li Chengqian sighed softly, and looked sideways at Li Ke: "Do you have the guts to mess around in front of Uncle Wuhuang?"

Li Ke shook his head heavily, he didn't have the guts!

"In all dynasties, there have been records of princes being demoted to common people. It is a good thing to learn some lessons. I am not gleeful, but telling you a fact. The longer I stay in the courtyard, the more afraid I am of Uncle Wu Huang! "Li Chengqian and Li Ke themselves have some disagreements.

The number of times the two quarreled was much higher than the number of normal conversations.

But there is one thing that they rarely agree on, that is, the longer they stay in this staff council, the more afraid they are of Li Yuanxing.No one can tell the reason for this inexplicable fear.

Li Chengqian and Li Ke were afraid of Li Yuanxing, so why not Li Yin.

Following behind Li Yuanxing, Li Yin felt a little trembling even when he was walking.

"Your Highness, Wanan!" The sergeant guarding the inner gate of Tiangong Workshop saluted, and then opened the gate.

Li Yuanxing walked straight to the children's tricycle: "Li Min, ride on it. Then get on it and turn around here. Don't ask, think for yourself!"

Li Yin is not stupid at all, although he is only seven years old, he is a very shrewd guy.

Soon, he knew how to step on the pedal with his feet, and then started to move the small tricycle.

"Your Highness, this thing can't run fast!" A craftsman said beside him.

Li Yuanxing ignored it, but asked, "How is your progress?"

The belt drive is too difficult, and it will make everyone embarrassed just by the meshing axle wheels.There is no way to master the balance of the two rounds.

But the craftsmen of Datang came up with this three-wheel pose by themselves, just for the sake of balance.

Li Yuanxing never mentioned this kind of tricycle.

"Your Highness, please take a look at this thing!" A craftsman applied the principle of a water press to a tricycle, with the force generated by the rear wheels, and the two pedals used the lever principle to drive the rear wheels.Every time the left and right feet are stepped on, the back [***] turns about three times, but there is a big flaw, that is, it is impossible for a person to sit down.

If you sit down, it will be more difficult.

It's far better to just stand like that, stepping on the left and right legs constantly.Li Yuanxing tried it himself. If he wants to make the car run fast, he still needs to spend some effort.

Compared with walking, it saves a lot of effort.

"Change, add a car board at the back, and then lengthen the lever. The length is eight feet to one foot, and then make a small one according to the shape of a child."

When Li Yuanxing was talking, he asked the guards to call Li Yin over again.

"Li Yin, you are right here. Follow the craftsmen to make this car. You can ride that kind of small car by yourself, and you can also add ten catties of iron. The king's request is that you must keep trying. From learning This car starts, when you can ride this car to pull a hundred catties of grain, the king will reward you."

Li Yuanxing was observing Li Yin.

Although Li Yin is a child, he has his own interests.

When Li Yuanxing was riding a bicycle by himself, Li Min's fiery eyes made Li Yuanxing make up his mind to give him a chance to learn and improve, and let him be the first prince to learn engineering technology.

"Thank you Uncle Wuhuang!" Li Yin was very excited.

"Don't bother the craftsman. If you don't understand, you can ask. You can put forward your own ideas, and you have to try it yourself. How can you save effort and let the car pull more things!" Li Yuanxing ordered, Li Yin not only nodded continuously, And take a small notebook to write down what Li Yuanxing said, for fear of forgetting something!

After getting permission from Li Yuanxing, Li Yin went to see the craftsman polishing the connecting rod.

In fact, Datang already had a woodworking lathe, which was originally operated by apprentices, but now it has been changed to a hydraulic one.Because it is impossible to stop the hydraulic power at any time, a craftsman actually designed the most primitive clutch. All of this is far beyond Li Yuanxing's imagination. Datang's technical strength has just not been developed.

Once the potential of craftsmen is stimulated, industrialization is just around the corner!

Li Yin was very attentive and asked many questions. The foreman specially asked a sixth-class craftsman to follow Li Pu to explain various problems. Li Yin was still in the mood to record every question carefully.

Only then did Li Yuanxing say to the foreman: "One-wheeled carts can be pushed by one person, but they have no strength. Two-wheeled carts will not be made in a while, so it is better to study this kind of tricycle. My king requested that one person can push it." Pulling five hundred catties can do two hundred miles a day. If you succeed before the spring plowing, the reward points for this time will be doubled. If you complete it within one month, add [-]%!"

"Yes! I will definitely do my best!"

"Pay attention to eat well and rest well. Craftsmen should pay attention to their safety and not get hurt because of fatigue. Whether it is pedal type or belt type, it is one of them that can meet the requirements of the king. The more important point is that it can be used, not like Like an ox cart, it can be used for at least a few years. But when the farming is busy, it must be reliable for several months in a row!"

Li Yuanxing ordered.

"Your Highness, I will test it carefully after I finish the work!"

"Very good!" Li Yuanxing nodded, turned and walked out, he did not mention Li Yin's identity.

In fact, there is no need to mention that in Qinwangzhuang, only the position is mentioned, not the status or rank.

Standing outside the gate of Tiangongfang, Li Yuanxing got a hint that surprised him.

The time machine, which had been silent for a long time, spoke: "Humans use tools better than beasts. The progress of human tools also represents the progress of human civilization. This is a great civilization."

"Great civilization, is it different from the civilization of a certain nation?"

"It is absolutely correct. It is worth mentioning that the progress of a great civilization can promote the progress of the entire human civilization." (To be continued.)
