The drive wheels designed by Li An can accommodate up to 6 people in each group at the same time. After being designed into 5 groups, the maximum number of drivers can be up to 30 people.

Although the driving force is still a bit small, the main structure of the rear car is made of wood, which is not too heavy, and the resistance is relatively small when traveling on the rails. It is still guaranteed to maintain the speed of the carriage.

In order to maintain manpower, there is a distance between each two sets of drive wheel mechanisms, and replacement manpower can be placed, so that the two groups of people can take turns to drive, so as to ensure that the front and the car continue to run forward.

When the vehicle is started, the required power is the largest. In order to reduce the pressure at the start, the connection of the 5 cars has been slightly improved. Before starting, the pressure hook must be processed to make all the cars as close as possible. Tight, in this way, when you start first, you only need to tow the first car, and use the inertia generated by the movement of the first car to drive the second car forward, and so on, it is easier to move all the cars Drive it up.

The technology of pressure hook and stretch hook is very skillful in the later generations and is a necessary technology for trains. With the current technology accumulation of Great Tang, of course, it is impossible to achieve such perfection, but fortunately Li An does not excessively pursue speed. Most of the quality is also made of wood, which is much lighter than the carriages of later generations, so the technical difficulty is naturally reduced accordingly.

Of course, because the interior of all cars are connected to each other, people can communicate with each other inside, so the pressure hook technology should also take into account the safety of internal passengers, the distance of the pressure hook should not be too long, so as not to walk between 2 cars Passengers cause injuries, of course, to ensure the safety of the connection room, and this problem, Li An has been very mature research, can definitely guarantee safety.

The Imperial Court transferred to Li An’s artisans who will be the supervisor and the engineering department. They have already gone to the site of the Research & Development Center on time to report to Li An.

And Li An ca n鈥檛 waste talents, let them immediately join the work of manufacturing 5 cars and 5 drive wheels. For these skilled people, they only need to give them drawings, and let them make products according to the drawings. , Don’t need to bother too much.

After the spring ploughing, the weather is getting warmer and the enthusiasm of the craftsmen is getting higher and higher. Li An has to run back and forth between the railroad track and the Research & Development Center every day. With 2 cars and 5 drive wheels, the leisure time becomes less and less.

Even so, Li An can still take the time to enjoy life. For example, Li An squeezed out some time and energy, and built a sun room near the mansion and the other courtyard, where several rocking chairs and soft beds were placed.

Especially the sun room near the Beyond Garden has the greatest effect. When Li An is tired of the guidance work, he will lie in it while basking in the sun while sleeping. It feels like a big cool word.

Spring is a season that makes people particularly sleepy. If it 鈥檚 not every day, you can spare some time to recuperate in the conservatory. Li An feels that his body ca n鈥檛 hold up. After all, he has to pamper Yan Ruyu after returning to the mansion at night Talking to Yan Ruyu about soap operas, and can’t sleep until late every day.

“How long has Minister Li slept?”

Li Yu looked towards Wang 8 who was guarding outside the sunshine room and asked.

“Back to Prince of Guangping, Minister Li has been asleep for an hour.”

King 8 answered truthfully.

“After lunch, I actually slept for so long, Minister Li can really sleep.”

Li Yu seemed dissatisfied. After all, he came to Li An, but Li An was sleeping, which made him very uncomfortable.

However, he did not dare to offend Li An. Although he was Emperor’s Grandson and Li Longji’s biological grandson, he knew very well that in his Emperor grandfather’s eyes, Li An’s weight was much larger than him, and Li Qiu was even more important. Think so.

“Prince of Guangping, the smell of Minister Li sleeping? Let’s wait until he wakes up!”

Li Qiu reached out and dragged Li Yu’s sleeves to the side.

Li Yu had no choice but to go with Li Qiu, hang out in the vicinity, and ordered the following guards to go to the vegetable greenhouse and pick a few cucumbers. He was angry and needed to eat cucumber to defeat the fire.

These escorts followed Li Yu all day long and were already very familiar with vegetable greenhouses. They even knew which cucumbers were the most succulent and most tender. They knew that, so they quickly completed the task and picked the best cucumbers. Submit to Li Yu and Li Qiu.

Hanging out while eating cucumbers, Li Yu’s mood suddenly improved a lot, and his irritability gradually calmed down. After all, he was eating cucumbers from Li An’s family. However, after eating a cucumber, Li Yu was a little upset, so I ate another one, but my stomach was limited. Moreover, shortly after lunch, Li Yu could n鈥檛 eat any more after 3 or 5 cucumbers fell in his stomach. Of course, his mood became very bad.

“You, come here, Minister Li, do you have to sleep so long every afternoon?”

Li Yu scolded Wang 8 and asked sharply.

“Back to the Prince of Guangping, the time for Minister Li to sleep is not fixed. The least time is only one hour, and the most time is from the afternoon until the sun sets.”

King 8 faithfully replied again.

“What, can you sleep until the sun goes down?”

Li Yu was in a daze for a while. If Li An fell asleep today until the sun sets, wouldn’t they wait for an afternoon.

“The ministers all said that it was very hard for Minister Li to inspect the two construction sites every day, but they did not know that Minister Li had to sleep here for so long every afternoon?”

Li Yu came sourly.

“Prince of Guangping, Minister Li is too tired, so I need more sleep.”

Li Qiu whispered that although he was waiting for Li An, he was cut off by Li Longji as a biological father of Crown Prince since childhood, so his character is relatively weak and he is not in a hurry to do anything.

“It’s too tiring, Xiao Wang doesn’t think so! Although Minister Li will visit the two construction sites in the future, they all take a look at the horse and don’t work with their own hands. How can they be tired?”

Li Yu apparently did not believe this explanation. He had seen Li An inspecting the construction site with his own eyes. He directed some officials of the Ministry of Industry and then rode a circle before leaving. For martial arts, the strong and young Li An Say, simply does not count, how can you feel tired?

“Will it be too late to study things.”

Li Qiu assumed a sentence and looked towards Wang 8.

Wang 8 hurriedly responded: “Minister Li does sleep late. It seems that he often falls asleep at midnight, but it seems that there is another reason.”

After talking, Wang 8 covered his mouth. He didn’t hold back for a while, and he talked nonsense.

“Another reason? What reason?”

Li Yu asked quickly.

“Minister Li will get busy soon after he gets married, so …”

King 8 whispered a reminder that the last look is clearly what you understand.

“Hahaha! It’s really embarrassing for Minister Li, hard, too hard.”

Li Yu smiled knowingly and felt much better in an instant, and looked towards side Li Qiu: “Fourth Son, how many chairs are there? Let’s go to sleep with Minister Li!”

“Prince of Guangping, I am not sleepy!”

Li Qiu looked dazed.

“Then you are here alone! Xiao Wang was very hard last night! Haha!”

Li Yu smiled heartily and quietly walked into the conservatory. He lay down on the chair next to Li An and learned Li An’s appearance, enjoying with his eyes closed.

“Since you are all hard, then I will work hard again!”

Li Qiu was tired too, followed in, and lay beside Li Yu.

The ventilation holes of the sun room are very small. After the sun shines in, the heat also follows, but the heat is not easy to radiate quickly. Therefore, the sun room is very warm, the temperature is much higher than outside, and the warmth is very comfortable. In this way, even Li Qiu, who is not sleepy, quickly fell asleep.

One hour later, Li An, who had a beautiful dream, woke up slowly and saw side Li Yu and Li Qiu.

“Wang 8, come in for me.”

“Master, what is it?”

King 8 cautiously walked into the conservatory.

“When did the 2 of them come in?”

Li An asked.

“It’s probably one hour.”

“They’re here, why don’t you wake me up?”

Li An accused.

“Master, they see you tired, and say you should rest a little longer.”

King 8 answered carefully.

Li An tilted his neck back and became lazy, opened the mouth and said: “Wang 8, go pick some cucumbers, I am thirsty.”

“Master, there are just a few here.”

Wang 8 quickly handed over some cucumbers in the sunshine room.

“Huh, when did you pick it.”

Li An asked suspiciously.

“Master, this is the Prince of Guangping who asked the guards to pick them up in the greenhouse. How about a dozen?”

King 8 faithfully replied.

“A dozen? Why are there three?”

“Ah … oh! The rest was eaten by Prince of Guangping and 4 Prince, and the last one was still outside.”

Wang 8 froze for a moment and answered truthfully.

“They are two, and after a while, I ate so many cucumbers. I can really eat them. Why didn’t I die?”

Li An scoffed angrily, looked towards Wang 8, and said softly: “Cut this cucumber into round slices.”

“Master, what is it for?”

“Fuck your face, hey, you ask so much, do your work quickly.”

Li An snorted and lay down slowly, the cucumber of the left right hand alternately stuffed into his mouth.

After so long exposure in the conservatory, he felt dry and very uncomfortable. Two cucumbers came under his stomach and he felt much more comfortable.

“Master, the cucumber slices are cut.”

Wang 8 handed the sliced 鈥嬧€媍ucumber slices to Li An’s hands.

“Okay, go out!”

Li An let Wang 8 leave, and put the freshly cut round cucumber slices on the face, the 2 largest ones are placed on the eyes, the forehead and 2 cheeks, including the chin are put a little, wet and cool Very comfortable.

“What time is it?”

Li Yu and Li Qiu wake up almost simultaneously.

“It’s almost evening, you can really sleep.”

“Wow … Minister Li, are you okay! What is on your face?”

Li Yu and Li Qiu were shocked when they saw the cucumber slices on Li An’s face.

“Cucumber slices, don’t you eat cucumbers every day? Why haven’t you seen cucumber slices?”

Li An spoke sarcastically and looked sideways, looking towards two people who were shocked.

“Minister Li, you are fine, how come you put cucumber slices on your face?”

Li Yu asked curiously.

“Cucumber slices are rich in moisture and various rare nutrients. Sticking cucumber slices on the face can play a good cosmetic role, delay the aging of facial skin, reduce wrinkles, and make the skin more supple. , In short, there are too many benefits, and I ca n鈥檛 make it clear for a while. “

Li An talked about a lot of benefits, but Li Yu and Li Qiu were confused, they had no concept of beauty in their minds, and of course it would be strange, and Li An 鈥檚 appearance was indeed very Scary.

However, the two of them understood the sentence and made the skin more supple, but this is what the young lady’s skin will pursue. Li An, as a rough man, how can this be pursued? This feels very strange.

“Minister Li, you shouldn’t be evil!”

Li Yu asked.

“Zhongxie, how could it be? I’m fine. There are some cucumber slices here. You can try it on your face.”

“Fourth Son, Minister Li’s illness is not light, let’s pass on the doctor!”

Li Yu and Li Qiu looked at each other in blank dismay. Regardless of how they understood it, they felt that Li An’s appearance is very difficult to understand, and it is an abnormal performance of the brain.

“Forget it, not enough, are you looking for me?”

Li An took the cucumber slices off his face and asked softly. He thought about it carefully, and really could not let Li Yu and Li Qiu know the benefits of cucumbers on the face. Otherwise, the cucumbers in the 500-mu vegetable greenhouse would suffer.

“Minister Li, this has passed half a month. Have you invented anything interesting again, we just want to come and see.”

Li Yu asked curiously, Li An invented things very frequently. They believed that Li An must have invented many things in this half a month.

“Uh, this half a month, I have been relatively busy. I have invented a lot of good things, but it is not very fun, nor is it something for people to play with.”

Li An answered.

“As long as it’s something new, we all want to see it.”

Since everyone is here, it’s not easy to go back empty-handed, you have to see something new, so this is worthwhile.

“Well, let me take you to see the solar cooker! This thing was created in recent days, and it is also a very amazing thing. You may be interested in it, and it is very popular in the Beijing area.”

Li An thought for a long time, and felt that only the solar cooker could reach it.

Li Yu and Li Qiu usually have homework to learn. Occasionally come to follow Li An, just for long-term knowledge, I heard that the solar cooker is a very magical thing, immediately interested, eagerly followed behind Li An, processing The factory walked.

“See it! This big guy is a solar cooker, isn’t it grandiose.”

Li An proud introduction.

“Minister Li, what does this solar cooker do, it looks so strange.”

Li Yu and Li Qiu looked around the cauldron lid for a long time, and they couldn’t figure out that this guy was used to do and so on.
