Elevator?

Gongshu Can was stunned for a moment; he had never heard of this name.

In fact, Liu Tan was not sure either.

In the past, everything he proposed was basically based on the technological level of this era. He basically threw aside things that were obviously impossible to produce in this era.

However, through his contact with Gongshujia, he felt that the elevator was basically between being able to make and not being able to make.

The reason why it can be done is that in large-scale construction, the transportation of materials has changed from manpower to mechanical assistance. Of course, this machinery is basically something like a pulley.

However, this is already a direction. If the elevator is not powered by electricity, then there is a very simple problem in front of us: how to make it rise.

The main body of the elevator can basically be regarded as a wooden box or a bamboo box.

In fact, using bamboo can reduce the weight of the elevator itself, but bamboo is soft, and it is easy to feel insecure when rising from the bottom up. If the bamboo is soft under your feet, it may make people feel even more terrified.

On top of the wooden box, which is more than one person tall, there are iron chains tied to the four corners. These chains must be tightly engaged with the gears, and the wooden box can be lifted up little by little through the rotation of the gears.

This is Liu Tan’s initial idea, so the question is, how can we make this gear turn?

The wooden box plus at least three people inside is not light in weight. In order to minimize the discomfort caused by shaking when the elevator rises, four iron chains are required to bear the weight at the same time. This makes the design more difficult than bearing the weight with only one chain.

Liu Tan looked at Gongshu Can and said, "Can this be solved?"

Gongshu Can looked at the diagram that His Royal Highness the King of the Northern Territory had casually drawn, stroked his chin, and said, "In that case, wouldn't it be enough to use the rotating mechanism of the waterwheel?"

Liu Tan pondered and said, "You mean to use the pulling force of the ox as the power of the elevator?"

Gongshu Can didn't know what power meant, but he understood the meaning of the sentence. He drew a diagram and said, "This mechanism isn't difficult, but the requirements for the iron chain are very high. There must be no problems."

Liu Tan asked, "Is the strength of an ox that great?"

Gongshu Can laughed and said, "Your Highness, you are joking. An ox can pull a waterwheel. How can three or four people plus a wooden box be heavier than a waterwheel?"

Liu Tan thought about it and agreed: "In this case, in order to ensure safety, it is best not to use wood, but an iron winch."

Gongshu Can hesitated: "I'm afraid it won't be easy."

Liu Tan waved his hand and said, "It's not hard to do. Go back and design a model. If there are no problems, put it into use."

Of course, when it is put into use, it must be tested with something else first.

Others liked to use slaves for testing, but Liu Tan couldn't bear it. After all, it was a human life, so he simply asked Gongshu Can to use pigs and sheep for testing.

Anyway, even if something goes wrong, we can still have an extra dish in the evening.

Before leaving, Gongshu Can asked, "Your Highness, do you have any requirements for the elevator?"

Liu Tan thought for a moment and said, "It has to be steady. It doesn't matter if it's a little slow, as long as it's steady."

Gongshu Can immediately said, "Okay!"

As soon as Gongshu Can left, Zhu Shanfu returned and said, "Your Highness, the road construction has been arranged."

Liu Tan nodded. Because the location chosen for the water park was relatively remote, there was no road leading there before. So even if the pool had not been dug yet, the road had to be built first. In this way, during subsequent construction, there would be a flat cement road and transportation would be easy.

Liu Tan didn't take this matter to heart at first, but when he saw Zhu Shanfu's hesitant expression after he finished speaking, he couldn't help but say, "Just tell me what you think, don't make me guess."

Zhu Shanfu was startled. He certainly didn't dare let Liu Tan guess what he was thinking, so he quickly said, "I just checked the length of the road that needs to be built. Your Highness... it's at least twenty miles from Changshou Palace to there. It's probably not easy to get Your Majesty all the way back to Changshou Palace in one day."

Liu Tan paused and couldn't help sighing.

Zhu Shanfu asked quickly, "I am the one who talks too much. Your Highness must have already..."

"No." Liu Tan interrupted him and said, "I've always felt like something was wrong. If you hadn't told me, I might have forgotten it."

He turned around, patted Zhu Shanfu on the shoulder and said, "If you have anything to say, just say it directly. Learn from Prime Minister Huo. How can I know if there is anything wrong if you don't tell me? Don't worry that I will be unhappy. As long as you don't scold me in public, nothing else matters."

Zhu Shanfu said hurriedly and fearfully, "Your Majesty...Your Majesty dare not."

Liu Tan laughed and said, "Don't be so cautious. It's been such a long time. When have I ever punished anyone carelessly?"

Zhu Shanfu agreed with what he said. His Highness not only did not punish people arbitrarily, but also did not violate the law or involve issues of principle. He basically turned a blind eye.

He is truly a very reasonable and soft-hearted prince.

Zhu Shanfu had also heard about the deeds of other princes from his mother. The more he thought about it, the more he seemed to understand why the emperor liked the King of the North so much - with so many troublesome elders, brothers, and sons, he finally met someone who was not only troublesome but also brought happiness. Who wouldn't like him?

After Liu Tan asked Zhu Shanfu to relax, he began to worry.

It is definitely too late to build another palace near the amusement park, and the distance is very awkward, neither close nor far. If he builds another palace, I am afraid that even if he can afford it, Chang'an will have something to say.

Those people probably wouldn't say Liu Che was extravagant, they would only say he was wasteful.

Of course, the most important reason was probably that there was no place particularly suitable for building a temporary palace. In order to make the scenery look better and less bare, Zhushanfu specially chose a place with trees.

The number of places with trees in the entire northern border can be counted together. This forest is mainly composed of elms and poplars. It is average in appearance, but at least it is green and pleasing to the eye, which is better than seeing only grass. After all, no matter how vast the grassland is, it may make you feel open-minded at first glance, but you will become aesthetically fatigued after looking at it for a long time.

Liu Tan looked at the forest, which looked quite large even on the map. Zhu Shanfu beside him whispered, "If it really doesn't work out, we can set up camp in advance."

camping?

Liu Tan looked at the woods and suddenly an idea struck him. He said, "I think there's a way."

Zhu Shanfu looked at Liu Tan, who smiled and said, "Since it's difficult to build a temporary palace, let's make this forest the temporary palace."

Zhu Shanfu was bewildered: "Your Highness means..."

Liu Tan slammed his hand on the table and said, "I want to build a tree house!"
