I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Liu Che knew that Liu Tan had been tinkering with something these days, but he was used to Liu Tan's behavior of retreating from time to time, so he didn't bother at all. Anyway, his son was playing with metal or mud. Just ask.

The most important thing is that if it is really useful and fun, his son will definitely offer it on his own initiative.

He originally thought that Liu Tan was going to take out the things tonight, but what did he hear?

His son took him to see the stars?

What's so nice about the stars?The most important thing is do I still need to bring it to see the stars?

This is Liu Tan. Although Liu Che is full of suspicion, he is still going to follow him to see what kind of tricks he is playing. If it is someone else, I am afraid that Liu Che will just let him go.

Since Liu Tan wanted to present the treasure, he had already decided on the most suitable place. If he wanted to see clearly, the higher the mountain, the better, but the problem was that the higher the mountain, the more difficult it was to go up. Not in the later generations, there are many wild animals in the forest, even if they bring many guards there, it will be very troublesome if they encounter a herd of wild boars or something.

Of course, it was impossible for Liu Tan to let Liu Che risk going to those places just to see the stars.

So he chose the highest place in this palace, which existed for sacrifices when it was first built.

The simple thinking of people nowadays is that the higher the altar, the closer they are to the fairyland and gods in the sky, and the easier it is to hear prayers.

However, since returning from the sea, these altars have been rarely used.

Liu Che seemed unable to face them, and didn't even want to hear about these altars.

Although the time is not long, but no one cares about it for a few months, these places are of course somewhat deserted.

Liu Tan asked someone to come and clean it when he stepped on the spot before. At that time, someone reminded him that His Majesty didn't want to hear him coming to the altar recently.

Liu Tan accepted the other party's kindness with a smile and gave the other party a silver pill.

In this palace, anyone who can remind him is considered a good person. Of course, it may have something to do with his favor in front of Liu Che.

Sure enough, Liu Tan didn't tell Liu Che where he was going at first, and when he took Liu Che all the way to the altar, Liu Che's expression was not so good.

Liu Tan saw that his footsteps had slowed down, so he stretched out his hand and pointed at the altar before him by the wrist, and said, "Father, do you think the star picking platform arranged by Erchen looks good?"

Liu Che was slightly taken aback: "Zhaixingtai?"

Liu Tan nodded: "It means that you can pick the stars with your hands."

Liu Che laughed and said, "This place is hundreds of thousands of miles away from the stars, and you can't even see them clearly. Do you still want to pick up the stars?"

Liu Tan raised his eyebrows: "Who said you can't see clearly? Let's go up and have a look."

When Liu Che went there, he found that the altar, or today's star picking platform, had already installed an elevator.

This was also created by Liu Tan. Fortunately, for things like elevators, he had people make all the parts in Chang'an, and when he got here, he could install them according to the height of the altar.

This elevator was originally used by him just in case.

Looking at the stars, the higher the better, he put his idea on the altar at that time. If the altar is available, then this elevator will naturally come in handy.

When Liu Che saw the elevator, he couldn't help but raised his eyebrows, and walked in without saying anything. He wanted to see what kind of medicine was sold in Liu Tan's gourd.

The speed of the elevator is not fast, and there is no view at night, but after waiting on the platform for picking up stars, Liu Che thinks the scenery here is really good - the palace under his feet is brightly lit, and Chang'an in the distance is also brightly lit. Can faintly see the lights of the stars.

At that moment, four words appeared in Liu Che's mind: fireworks in the world.

He raised his head again, and found that the stars were indeed much more obvious when standing here, and he didn't know if it was his illusion.

After Liu Che looked around, he found that Liu Tan was not by his side. When he turned his head, he saw his son directing people to install something.

He walked over and saw that three sticks connected at one end had been poked on the ground. He couldn't help but ask, "What is this?"

Liu Tan said: "This is a tripod, it's for placing the binoculars."

Telescope?

He hadn't heard of this word before, but since the word he hadn't heard appeared, it meant that his son had indeed created something new, and this time looking at the stars was also one of the behaviors of offering treasures.

Liu Che simply sat aside and watched quietly as Liu Tan took the tripod and looked for the most suitable place to put it down, and then the person who came up behind brought out a box.

Liu Che is now very capable of judging the value of items by the packaging Liu Tan used to place them.

When he saw that the box was made of mahogany and inlaid with mother-of-pearl and mother-of-pearl, he knew that the things inside must be very precious.

Liu Tan was not in a hurry to put the telescope on the tripod, but first sat opposite Liu Che and put the mahogany box on the table, then gently opened it and said, "Father, this is the latest telescope made by Erchen. meaning far away."

"Seeing thousands of miles away?" Liu Che was a little surprised: "There is such a thing in the world?"

Liu Tan smiled shyly and said: "If you really want to say it, it will definitely not be achieved, but that is also because the current production technology is not enough. If it is enough, it is not a strange thing."

Don't talk about thousands of miles, ten thousand miles will do, and not only can observe the human world, but also the universe!

It's a pity that he probably won't see that level of astronomical telescope in his lifetime.

However, if you think about it, it's best not to have it, or how many people in the big man will have their worldview collapsed?Especially Liu Che, who gave up looking for immortals before made him so uncomfortable, and told him that there is no immortal world in this world at all, the earth is round, and the outside of the earth is a dark universe, and he is afraid that something will go wrong.

The best way to develop science is to develop it bit by bit, and it cannot be achieved overnight. In history, the development of science bit by bit has caused countless people to dedicate themselves to science, the collapse of countless people's worldview, and the pursuit of countless people's life. It has become a joke, if suddenly those sciences are force-feeded to the present people, and all kinds of arguments are made, either those who tell the truth will be killed, or the knowledge system of the whole society will collapse directly.

Anyway, it's not a good thing.

When Liu Tan was distracted, Liu Che had already picked up the telescope and started playing with it.

"This is...glass?" Liu Che looked over and over at the two cylinders.

Liu Tan came back to his senses and replied: "Yes, when using it, let the small one close to the eyes, and then see it."

There is nothing difficult to understand about this. Liu Che picked it up and tried it, and then... he was taken aback.

When he tried it, he was talking to Liu Tan, and when he looked over, he saw his son's face magnified a lot.

Even if Liu Tan's face can hold the telescope so magnified, the problem is that it's quite scary if it comes all of a sudden.

Liu Tan looked at Liu Che with an innocent face, but at this time Liu Che had already reacted after the initial shock. He used the binoculars to look at Liu Tan's face for a while, and then took it down and looked at it with his eyes. He tried many times. .

He didn't think there was anything, and Liu Tan was about to collapse: "Father, there are many things that can be seen in the binoculars, can you look at other things first?"

If you have nothing to do and have to use a telescope to look at your face, is that still a telescope?That's a magnifying glass!

Liu Che shifted his place with a proud smile, and looked around, and found that the binoculars were really powerful. The palace under his feet seemed to be right in front of him, and even the Chang'an City in the distance could even see some people shaking.

After Liu Che saw that the surroundings were almost the same, Liu Tan said: "Father, the binoculars are also very useful for looking at the stars."

It was only then that Liu Che remembered that when Liu Tan called him over just now, he had told him to go to see the stars.

He raised his head and looked at the stars in the sky. The moment he raised his head, he couldn't help holding his breath, and stretched out his hand subconsciously—the stars seemed to fall in front of his eyes in an instant, and as long as he stretched out his hand, he could Met in general.

At this moment, Liu Che suddenly understood what Liu Tan meant by the platform for picking up stars.

With this telescope, it is true that the stars are within reach at a glance.

However, after taking it down, those stars went away again.

Liu Che felt a little lost for a moment, he just put down his hand when he was tired from lifting it, Liu Tan observed this and immediately said: "Father, the binoculars can be placed on this tripod, and then you can watch as you like."

Liu Che handed over the telescope and watched Liu Tan press the telescope on the top of the tripod, and then the telescope formed a tilted angle.

Liu Tan also made the kind of tripod that can be extended and retracted. This function is not difficult for Mojiu and Gongshuchuan, but because he needs it urgently, if it is made of metal, it will be slower to make a model. Gongshuchuan and Gongshuchuan simply made a wooden one with their hands.

Liu Tan helped Liu Che adjust the height of the tripod so that it could match Liu Che's sitting height, and said: "The tripod should be made of metal, which is stronger, and I will have someone replace it later, and it can be rotated here. Yes, if you want to see the stars in other directions, just turn around."

After installing it, he put the telescope in front of Liu Che. Liu Che leaned forward slightly, moved his eyes to take a look, and the sky full of stars fell into his eyes again.

Liu Che stared at it obsessively for a long time. He already knew very well that the telescope just magnified the stars so that he could see them more clearly. It wasn't that the stars were really close. However, he still couldn't help being obsessed with it.

After a while, he couldn't help asking: "Above the stars, are there people living there?"

Liu Tan paused and said, "I don't know, but I think... yes!"
