Chapter 567 [Second Update] 567

Liu Tan's question was subtle, but Liu Ju understood what he meant. He sighed and said, "Although the incident at sea previously seemed fine to Father, it was still a huge blow to him."

After all, we have been drifting for so long and haven’t seen any fairy mountains. The journey has been magnificent, but it’s all in the human world.

Liu Che vaguely felt that he might not be able to see the immortals or go to the fairyland.

He never doubted the existence of that place. Even if he did doubt it at first, he no longer doubted it after Liu Tan returned to the palace.

It exists in the fairy world, but unfortunately he has no chance to see it.

No matter how strong Liu Che was inside, he couldn't help feeling negative and lost, so he basically gave up the idea of ​​continuing to search for the immortal world and began to think more about what would happen after his death.

In fact, he found that even if he left immediately, there was not much to worry about.

The Han Dynasty had entered a very stable period of development. Of course, he was still worried about Liu Ju. However, no matter how mature Liu Ju was, he was still a child in his eyes and there were some things he was not considerate of.

His father Emperor Jing also viewed him this way at the beginning, but apart from the initial confusion when he ascended the throne, Liu Che also gradually got through it.

He believed his son could do it too.

The only person we need to worry about is probably Liu Tan, who insists on staying in the Northern Border Kingdom and refuses to come back.

Liu Tan always thought that he was very quick to take revenge and never let a grudge go unpunished. But in Liu Che's view, he was still too stupid. According to Liu Che's logic, when I find that you have any signs of doing something bad to me, I will kill you.

Isn’t this taking precautions before problems arise?

As for revenge, no matter how hard you hit back, you will be the one who gets hit first.

So Liu Che was very worried, extremely worried that if he was gone one day, the child would suffer.

So much so that he no longer has the idea of ​​abolishing the queen.

If he went, he would definitely issue a will to make Chen Ajiao the empress dowager. A empress dowager might not have much effect, but at least it could provide Liu Tan with an extra layer of insurance.

Liu Ju didn't say these words, but the few sentences he said before were enough for Liu Tan to understand.

He couldn't help but sigh. This was his negligence. Liu Che had been very strong-willed throughout his life, and even if he was frustrated, he would never let anyone see it.

For a moment, Liu Tan actually felt a little sorry for him.

This even led him to think that there was nothing wrong with Liu Che wanting to live forever. Even ordinary people would say that it is better to live a miserable life than to die. To be more civilized, even ants try to survive.

There is nothing wrong with someone like Liu Che, who has made great achievements and firmly believes that he can still achieve more, wanting to live.

Liu Tan knew that he was being hypocritical. Liu Che's problem was not that he wanted to be immortal, but that he did many foolish things in his pursuit of immortality.

After thinking about it carefully, he decided to prepare something fun and delicious for his father. Mood can greatly affect a person's health.

Liu Che had been pursuing something for half his life, and now he suddenly gave up. No one would be willing to accept this. The more determined a person is, the greater the hurt they will suffer.

It just so happened that Liu Che might go to the palace in Mount Li for a visit in a couple of days. The terrain there was high, so Liu Tan could come up with something new.

In fact, Liu Tan wanted to try this new thing when he went out to sea, or rather, after going out to sea, he found that he had overlooked one thing, which led to his lack of preparation. However, he did not have anything suitable at hand at the time, so he could only give up with regret.

That thing is a telescope.

In fact, the telescope is relatively simple compared to some of the things he made before, but Liu Tan had always had concerns before - this thing is too invasive of privacy.

You should know that the houses of the Three Dukes and Nine Ministers are generally next to the imperial palace, which means that once there is a telescope, these people can climb onto the roof of their own house to see what is happening in the palace.

Of course, the rammed earth platforms of Weiyang Palace and Jiaofang Palace are very high, so it is not easy to see clearly inside these two palaces. Some ordinary buildings are no problem.

The emperor's harem is a little far away and may not be clearly visible, but the prince's family members are all in the prince's palace, which is an independent palace and is also at the easternmost end, now next to Liu Tan's mansion.

That means that anyone living in Liu Tan's position can see the prince's family by simply climbing onto the roof and using a telescope.

This is a bit too offensive.

Moreover, it is impossible for the armed guards to patrol even the roofs. In addition, the roofs nowadays are all in a V-shape when viewed from the side. People hiding on the other side cannot be seen on this side. If you run to this side, they can still hide on the other side, unless they can patrol in the sky.

But if such technology really existed, I believe Liu Che would have already started thinking about how to go to heaven.

This led to Liu Tan realizing that they needed a telescope only after they went out to sea.

This thing is very useful at sea.

But he didn't have the means to do that at the time. He didn't have any glass or crystal. After all, he was going out to rescue people, so how could he possibly bring these things? Unless he removed all the glass from the boat, then the question was, what would he do if he encountered a storm? Would he use his body to block it?

Not to mention arriving on Luzon Island. Unless he set up a glass workshop on that island, there would be no raw materials.

So the question is... he can build a glass workshop, but where can he find craftsmen?

The difficulties were so numerous that Liu Tan finally gave up.

Now he wanted to give Liu Che something new to play with, so he naturally thought of the telescope.

Anyway, he made it first and gave it to Liu Che. He could do whatever he wanted with it. If Liu Che chose to treasure it, Liu Tan would feel sorry but would not say anything.

Telescopes are both simple and complex. After all, there are many types of them, including monoculars and binoculars. From ordinary telescopes to astronomical telescopes, the craftsmanship involved is not at the same level.

Liu Tan actually seems to be interested in making an astronomical telescope, but unfortunately, there is no such sophisticated technology now.

A telescope is composed of an objective lens and an eyepiece, among which the objective lens is a relatively important link. The objective lens is generally composed of a combination of lenses. In fact, if it is a simple telescope, it is not impossible to use a single lens, but a single lens is prone to cause phase difference. Therefore, not only the objective lens needs a group of lenses, but the eyepiece also still needs a group of lenses.

To put it simply, the simplest telescope can see far away, but it is generally not made with enough precision, so the effect is distorted. You can see it, but the houses are crooked and the people are in all kinds of strange shapes, just like those people standing in front of a funhouse mirror.

Of course, Liu Tan would never let Liu Che play with this thing. Not to mention whether it was exquisite or not, the main reason was that looking at it too much would be bad for the eyes and would easily cause dizziness.

He thought about this matter for a long time, and finally asked the Mohist and Gongshu schools to send a few smart and clever disciples each.

Now these two families have basically shifted their focus to him. Mo Shi and his team are now working overtime to continue their research on the ship. It is impossible for Mo Shi to ignore the opportunity they have obtained.

So it’s not surprising that they started to move closer to Liu Tan.

Not to mention the Gongshu family, they had already defected to Liu Tan.

At this point, Liu Tan could reveal a little about his true intentions - he never wanted to rely on a certain school of thought. What he wanted was the most advanced technology. It didn't matter who had the technology, as long as he could use it.

As for whether these two families will be unhappy, he doesn’t care. If you have the ability, just don’t come.

This is the confidence of holding resources in your hands.

Gongshujia and Mojia were indeed reluctant to come. If they didn't come, one would gain while the other would lose. It would not only be a matter of them not getting what they wanted, but it might also allow the other party to take a further step. The difference between the inside and the outside was too big.

The person who came from the Gongshu family was Gongshu Can's nephew, Gongshu Chuan, while the Mo family simply sent Mo Jiu.

Liu Tan wasn't very familiar with Gongshu Chuan, and had never met him before, so he was a little surprised when he saw Mo Jiu: "How did you find time to come here? Didn't you go help Mo Shi?"

Mo Jiu scratched the back of his head and said, "Well... I have limited achievements in that area, and I don't understand many things. The eldest brother disliked my slow work and sent me back."

Liu Tan laughed after hearing this: "Then I have to make it clear first, if you don't complete the tasks I ask you to do quickly, then I will also send you back."

Mo Jiu said confidently, "Don't worry, Your Highness. I heard that you are going to play with glass this time. Hehe, I love playing with glass the most."

Liu Tan looked at him deeply and said, "You'd better remember this." There will be a time for you to cry.

Gongshu Chuan, who was standing by, did not show any reaction when he saw that Liu Che and Mo Jiu were quite familiar with each other. Although he looked a little restrained sitting there, he knew not to interrupt and did not make any small movements, which was pretty good.

Liu Tan said directly: "Don't worry about what I want you to make next. Just make it, and then improve it based on its shortcomings."

Gongshu Chuan was a little surprised: "Just...just like that?"

Since His Royal Highness the King of the North already has the finished product, why does he need them to come?

Even if it's just a blueprint, two craftsmen can make it.

Liu Tan nodded. "That's it. However, you've never worked with me before, so you might not understand. I don't want you to recreate something. I want you to make it more exquisite and advanced based on my original. I can only provide the basics. As for upgrading this basic level, that's your business."

Gongshu Chuan glanced at Mojiu and found that Mojiu didn't seem surprised at all.

In fact, after working under Liu Tan for so long, he was not surprised by this method. The only thing he needed to do was to try to calm down his disappointment. It was true that these people were good at craftsmanship, but there were so many people with good craftsmanship in the world. It was very rare for them to invent something on their own.

What these people are most proud of is that they have flexible brains and can create many strange and bizarre things.

It’s a pity that the gap between their so-called smart brains and the King of the North is simply too huge.

For example, now His Royal Highness the King of the North handed them a blueprint, and the two of them looked at it for a long time but still couldn’t understand what it was!
