The driving wheels designed by Ang Lee could accommodate up to six people at the same time. After designing it into five groups, it could accommodate up to thirty people.
Although the driving force was still a little small, the main structure of the carriage at the back was made of wood, so it was not too heavy. Moreover, the resistance was relatively small when traveling on the rails, so it was still guaranteed to maintain the speed of the carriage.
In order to maintain manpower, there was a distance between every two groups of driving wheels to allow for replacement manpower. This way, the two groups of people could take turns to drive, thus ensuring that the front of the carriage and the carriage would continue to move forward.
When the carriage was started, it required the most strength. In order to reduce the pressure during the start, the connection of the five carriages had been slightly modified. Before the start, it was necessary to press the hooks so that all the carriages were as close as possible. This way, when the first carriage was started, it only needed to pull the first carriage and use the inertia generated by the movement of the first carriage to drive the second carriage forward, and so on. It was easier to move all the carriages together.
The techniques of pressing hooks and stretching hooks were used very skillfully in the future. It was a necessary technique for the train. With the current accumulation of technology in the Tang dynasty, of course, it was impossible to make it so perfect. Fortunately, Ang Lee did not pursue speed too much. Most of the quality of the train was also made of wood, which was much lighter than the carriages of the future. Therefore, the technical difficulty was naturally reduced accordingly.
Of course, because the interior of all the carriages were connected, people could come and go inside. Therefore, the pressing hooks had to take into account the safety of the passengers inside. The distance of the pressing hooks could not be too long to avoid causing harm to the passengers walking between the two carriages. Of course, it also had to ensure the safety of the connecting rooms. Ang Lee had already studied this problem very well, so it could definitely guarantee the safety.
The construction supervisor and the craftsmen from the Ministry of Works, who were assigned to Ang Lee by the imperial court, had already gone to the construction site of the R&D Center on time to report to Ang Lee.
Li An didn't want to waste talents, so he immediately got them to work on the production of the five carriages and five driving wheels. For these skilled talents, he only needed to give them the blueprints and let them build the products according to the blueprints. There was no need to spend too much effort on them.
After the spring plowing, the weather became warmer and warmer, and the craftsmen became more and more enthusiastic. Ang Lee had to run back and forth between the railway tracks and the research and development center every day. In addition, he also had to guide the craftsmen in building the five carriages and the five-wheeled locomotive at the factory. His leisure time was becoming less and less.
But even so, Ang Lee was still able to find time to enjoy life. For example, Ang Lee squeezed out some time and energy to build a sunroom near his residence and his courtyard. There were several rocking chairs and soft beds inside.
This was especially true for the sunroom near the courtyard. It had the greatest effect. Every time Ang Lee was tired from his work, he would lie down and bask in the sun while sleeping. That feeling could only be described with one word: awesome.
Spring was a season that made people feel sleepy very easily. If it wasn't for the fact that he could take some time out every day to catch up on his sleep in the sunroom, Ang Lee felt that his body wouldn't be able to take it. After all, after returning to the mansion at night, he still had to pamper Yan Ruyu and tell her soap operas. Every day, he had to toss and turn until very late before he could sleep.
"How long has Assistant Minister Li been sleeping?"
Li Yu looked at Wang Ba, who was standing guard outside the sunroom, and asked.
"When we returned to Gwangbyeong Of Gojoseon, Assistant Minister Li has already slept for two hours."
Wang Ba replied truthfully.
"He actually slept for so long after lunch. Assistant Minister Li really can sleep."
Li Yu seemed to be somewhat dissatisfied. After all, he had come to find Ang Lee, but in the end, Ang Lee was sleeping. This made him very unhappy.
However, he didn't dare to offend Ang Lee. Even though he was the imperial grandson, Li Longji's grandson, he knew very well that in the eyes of his imperial grandfather, Ang Lee was much more important than him. Li Qiu felt this way even more.
"Gwangbyeong Of Gojoseon, Assistant Minister Li is sleeping soundly. Let's wait until he wakes up! "
Li Qiu reached out and tugged at Li Yu's sleeve as he walked to the side.
Li Yu had no choice but to accompany Li Qiu and stroll around nearby. He also ordered the guards to go to the vegetable shed and pick a few cucumbers. He had anger in his heart and needed to eat cucumbers to relieve his anger.
These guards had been following Li Yu all day and were already very familiar with the vegetable shed. They even knew which shed had the most and most tender cucumbers. Therefore, they quickly completed their task and picked the best cucumbers to pass to Li Yu and Li Qiu.
As they strolled around while eating cucumbers, Li Yu's mood instantly improved. His irritation gradually calmed down. After all, he was eating Ang Lee's cucumbers. However, after eating one cucumber, Li Yu felt a little irritated again, so he ate another one. However, a person's stomach was limited. Moreover, not long after lunch, Li Yu couldn't eat anymore after eating three to five cucumbers. His mood naturally became bad.
"You, come here. Does your Assistant Minister Li sleep for so long every afternoon?"
Li Yu reprimanded Wang Ba and asked sternly.
"In Gwangbyeong Of Gojoseon, Assistant Minister Li doesn't sleep at a fixed time. At the very least, he sleeps for an hour. At the very most, he sleeps from afternoon until sunset."
Wang Ba replied truthfully again.
"What, he sleeps until sunset at the very most?"
Li Yu was dumbfounded. If Ang Lee also slept until sunset today, then wouldn't they have to wait for an entire afternoon?
"The ministers all said that Assistant Minister Li has to go back and forth between the two construction sites every day and that it's quite tiring. However, they don't know that Assistant Minister Li sleeps here every afternoon for so long."
Li Yu said sourly.
"In Gwangbyeong Of Gojoseon, Assistant Minister Li is too tired. That's why he needs more sleep," Li Qiu explained softly.
Li Qiu explained softly. Even though he was also waiting for Li An, his father, the Crown Prince, had been executed by Li Longji when he was young. As such, his personality was relatively weaker and he wasn't in a hurry to do anything.
"Too tired? Xiao Wang doesn't think so! Although Assistant Minister Li inspects the two construction sites every day, he only rides on a horse to take a look. He doesn't have to do any work himself. How could he be tired? "
Li Yu clearly didn't believe this explanation. He had personally seen Ang Lee inspect the construction sites. He only gave some instructions to a few officials from the Ministry of Works, then rode a horse around and left. For the young and powerful Ang Lee, it was nothing. How could he be tired?
"Could it be that he slept too late because he was researching something?"
Li Qiu hypothesized and looked at Wang Ba.
Wang Ba hurriedly replied, "Assistant Minister Li does sleep rather late. It seems like he often goes to bed in the middle of the night. However, there seems to be another reason."
After saying this, Wang Ba covered his mouth. He couldn't help but speak carelessly.
"Another reason? What reason? "
Li Yu hurriedly asked.
"Assistant Minister Li just got married. Of course he's busy, so …" Wang Ba whispered softly.
Tortoise reminded him in a low voice. The look in his eyes clearly said, "You understand."
"Hahaha! This is really hard on Assistant Minister Li. It's hard on him, too hard on him. "
Li Yu smiled knowingly. His mood instantly improved a lot. He looked at Li Qiu beside him and said, "Fourth Brother, how many chairs are there inside? Let's go in and sleep together with Assistant Minister Li! "
"Gwangbyeong Of Gojoseon, I'm not sleepy!"
Li Qiu was dumbfounded.
"Then you can wander around here alone! Xiao Wang also worked hard last night! Haha! "
Li Yu smiled knowingly and quietly walked into the sunroom. He lay down on the chair next to Ang Lee and closed his eyes to enjoy himself like Ang Lee.
"Since all of you have worked hard, then I'll work hard too!"
Li Qiu was also tired from walking. He followed in and lay down next to Li Yu.
The ventilation hole in the sunroom was very small. When the sunlight shone in, the heat also entered. However, the heat couldn't be easily dissipated. Therefore, the sunroom was very warm. The temperature was much higher than outside. It was warm and comfortable. As such, even Li Qiu, who wasn't sleepy, fell asleep very quickly.
An hour later, Ang Lee, who had a beautiful dream, slowly woke up. He saw Li Yu and Li Qiu beside him.
"Wang Ba, come in."
"Alang, what's the matter?"
Wang Ba carefully walked into the sunroom.
"When did the two of them come in?"
Ang Lee asked.
"It's been about an hour now."
"They came. Why didn't you wake me up?"
Ang Lee asked accusingly.
"Alang, they saw that you were tired and said to let you rest for a while."
Wang Ba carefully answered.
Ang Lee stretched his neck back and said lazily, "Wang Ba, go and pick a few cucumbers. I'm thirsty."
"Alang, there are a few here."
Wang Ba hurriedly handed over a few cucumbers in the sunroom.
"Hey, when did you pick them?"
Ang Lee asked suspiciously.
"Alang, Gwangbyeong Of Gojoseon asked the guard to pick these from the greenhouse. He picked a dozen cucumbers."
Wang Ba answered truthfully.
"A dozen? Why are there only three left? "
"Ah … Oh! The rest were eaten by Gwangbyeong Of Gojoseon and the Fourth Prince. The last piece was left outside. "
Wang Ba was stunned for a moment and answered truthfully.
"The two of them ate so many of my cucumbers in such a short time. They can really eat. Why aren't they stuffed to death?"
Ang Lee reprimanded angrily. He looked at Wang Ba and said softly, "Cut this cucumber into thin round slices."
"Alang, what are they for?"
"Apply them on my face. Hey, why are you asking so many questions? Hurry up and get to work."
Ang Lee reprimanded and slowly lay down. He took turns stuffing the cucumbers into his mouth.
After being in the sunroom for so long, he felt very dry and uncomfortable. After eating two cucumbers, he immediately felt much better.
"Alang, the cucumber slices are ready."
Wang Ba handed the sliced cucumber slices to Ang Lee.
"Okay, you can leave now!"
Li An asked Tortoise to leave and stuck the thin slices of the freshly cut cucumber on his face. The two largest slices were placed on his eyes, forehead, cheeks, and chin. It was wet and cool, and it felt very comfortable.
"What time is it?"
Li Yu and Li Qiu woke up almost at the same time.
"It's almost evening. You guys can really sleep."
"Wow … Assistant Minister Li, are you okay? What's on your face? "
Li Yu and Li Qiu were shocked when they saw the cucumber slices on Ang Lee's face.
"It's cucumber slices. Don't you eat cucumbers every day? Why haven't you seen cucumber slices before? "
Ang Lee said sarcastically. He turned his head slightly and looked at the two shocked people.
"Assistant Minister Li, why did you put cucumber slices on your face?"
Li Yu asked curiously.
"Cucumber slices are rich in water and various rare nutrients. Putting cucumber slices on your face can have a very good beautifying effect. It can delay the aging of the face, reduce wrinkles, and make the skin more supple. In short, there are too many benefits. I can't explain them all in a short time."
Ang Lee talked about a lot of benefits. However, Li Yu and Li Qiu were confused. They didn't have the concept of beautifying in their minds. Of course, they would find it strange. Moreover, Ang Lee's appearance was indeed very scary.
However, the two of them understood that it could make the skin more supple. This was something that only young girls would pursue. As a rough man, how could Ang Lee have such a pursuit? This made them feel very strange.
"Assistant Minister Li, you're not possessed, are you?"
Li Yu asked with concern.
"Possessed? How could that be? I'm fine. Here are some cucumber slices. You guys can try putting some on your face. "
"Fourth Brother, Assistant Minister Li is seriously ill. Call the imperial physician!"
Li Yu and Li Qiu looked at each other. No matter how they understood it, they felt that Ang Lee's current state was very difficult to understand. It was a sign that there was something wrong with his brain.
"Forget it. I won't put it on. Is there anything you want from me?"
Ang Lee took off the cucumber slices on his face and asked softly. He thought carefully. He really couldn't let Li Yu and Li Qiu know the benefits of putting cucumber slices on their faces. Otherwise, the cucumbers in the 500 mu vegetable greenhouse would suffer.
"Assistant Minister Li, it's been half a month. Did you invent something fun again? We just wanted to come over and take a look."
Li Yu asked curiously. Ang Lee's frequency of inventing things was very high. They believed that Ang Lee must have invented a lot of things in the past half a month.
"Uh, I've been busy for the past half a month. I've invented a lot of good things, but they're not very fun. They're not for people to play with."
Ang Lee answered.
"As long as it's something new, we want to see it."
Since they were already here, it wouldn't be good to go back empty-handed. They had to see something new to make this trip worthwhile.
"Yes, I'll bring you to see the solar stove! This thing was invented in the past few days. It's also a very magical thing. You might be interested in it. Moreover, it's very popular in the capital. "
Ang Lee thought for a long time and felt that the solar stove was the only thing he could bring out.
Li Yu and Li Qiu also had homework to learn. They occasionally came to follow Ang Lee to broaden their horizons. When they heard that the solar stove was a very magical thing, they immediately became interested and followed Ang Lee to the processing plant.
"See? This big thing is the solar stove. Isn't it very stylish? "
Ang Lee introduced proudly.
"Assistant Minister Li, what's this solar stove for? It looks very strange."
