Liu Tan put down Liu Che's letter, thought about it again and again, and finally wrote a reply. Of course, he only reported good news and not bad news, and reported the progress of the city construction to Liu Che. By the way, he lamented that his city plan was a bit too big, and the people had not moved back yet.

He didn't say anything else, turned around and picked up the sight that the Gongshu family had given him.

When he gave the sight to the Gongshu family, he specifically did not tell him how to design these movable parts. However, he was surprised that the parts that needed to be adjusted were completely different from those in later generations, but it still surprised him a little.

For example, the up and down adjustment of the aiming frame is achieved by adding a handle to the aiming frame, and the adjustment is achieved by pushing it up and down and pushing and pulling it.

This is naturally less refined than later ones, but it is sufficient for use. This adjustment is originally intended to cater to personal habits.

Liu Tan originally wanted to give it a try, but after thinking about his own level, he had to let Li Buyan and Wei Buyi take the test.

Neither of them is particularly good at this, but neither is bad either. Each of them has a different focus, which allows them to better test the practicality of the adjustable sight.

When Li Buyan got the bow with the sight, his eyes lit up. After hearing what Liu Tan said, he patted his chest and said, "Don't worry, Your Highness! Even if the sight can't be adjusted, I can still hit the target with every arrow!"

Liu Tan looked at him expressionlessly and said, "Just do whatever I tell you to do, or else I'll get someone else to do it."

Wei Buyi, standing by, suppressed a smile and said, "I understand what Your Highness means."

Liu Tan was still very gentle towards Wei Buyi. After all, compared with the silly Li Buyan, Wei Buyi really seemed very smart.

He was puzzled. He remembered that Li Buyan was not like this when the news first came. How come this young nobleman who looked very gentle became more and more stupid?

Li Buyan and Wei Buyi went to try it out. It must be said that even though Li Buyan said that the sight did not need to be adjusted, he was really impressed when he could actually adjust it.

He had used Liu Tan's bow before, but that bow was customized by Liu Tan according to his own habits. Li Buyan never felt comfortable using it. Now that he knew how to adjust it, he felt like he had become a sharpshooter and fell in love with this feeling.

After they finished their tests, Liu Tan nodded, confirming that the Gongshu family was still quite capable. He then turned to Huo Guang and asked, "Can we equip it with a sight?"

If they could be equipped with a sight, their combat effectiveness would be greatly improved.

Although their army may not be much worse than the Huns now, if they are of the same level and have better equipment, wouldn't they be able to crush them?

Huo Guang looked at Liu Tan expressionlessly and said, "Your Highness, the treasury has just received some money. Can we not squander it?"

This little bit of money will last until the autumn harvest!

And to be honest, the armaments and other things used in wars nowadays are not prepared by the imperial court, but by individuals. As long as it is not related to iron, the imperial court will not provide it.

It sounds absurd that soldiers are born to defend their country, but in the end they have to take their own life and death, and have to buy all kinds of things by themselves, such as leather armor and horse harness.

So when Huo Guang heard Liu Tan say this, his first reaction was that their prince was having a seizure again.

Liu Tan sighed. He knew a lot of things, but the values ​​he had developed over the years were not easy to change.

In his impression, not only will the government provide salary subsidies for soldiers, but clothing and daily necessities will also be provided by the government, not to mention weapons.

But when it got here, it became a fantasy.

Liu Tan rubbed his hands and said, "Then...if I were to arm my own troops, this wouldn't be a big deal, right?"

Huo Guang asked a soul-searching question: "Do you want to be thought of as a rebel?"

Liu Tan: ...

Finally, he said simply, "Then I can just use the portion of the tax that belongs to me, right?"

Yes, although the tax revenue of the Northern Border Kingdom belongs to the imperial court, only a very small portion of it is actually used to develop various scientific and technological livelihoods and infrastructure. Otherwise, how can the extravagant lives of the princes be supported?

To be frank, this means that the princes and their families basically do not engage in production, but they occupy most of the money.

This is something that cannot be changed by the feudal dynasty now or in the next few thousand years, and Liu Tan has no intention of changing it, but he can use his own money however he wants. Is there anything wrong with that?

He had wanted to avoid breaking the rules before, but now he has come to terms with it. He feels that he alone would not break the rules, not to mention that he has a ready-made reason - to protect himself.

The other princes don’t need to face the Huns, right?

Uh, I forgot about King Liu Dan of Yan. This... just ignore it. There's no way to backstab him. What's more, there was really no Huns invasion in Liu Dan's place. After all, compared to Yan State, Shuofang was more coveted by the Huns.

The most important thing is that Shuofang is relatively close to Chang'an. If Shuofang is captured, we can basically march straight to Chang'an.

This is also one of the reasons why Liu Che felt that the location of the Surrender City was not far enough.

Huo Guang choked. He had been trying every possible way to save money recently just because he didn't want to use the part of the tax revenue that was to be given to Liu Tan.

Not to mention his deep-rooted thoughts, deep down in his heart he would rather slow down the pace of building the city or arming, rather than affect Liu Tan's life.

It turns out that the owner himself doesn’t care!

Huo Guang subconsciously advised, "Your Highness should save some money. Nowadays, the popular things among the princes and nobles are very expensive. If Your Highness likes them but has no money, wouldn't you be sad?"

Liu Tan laughed and said, "What I like is more valuable. I like building cities!"

What those people call burning money is nothing. Liu Tan is really burning money, and he does it in an extremely grand manner.

Huo Guang was choked by him and said helplessly: "You said it yourself."

Liu Tan said calmly: "Yes, that's what I said."

Huo Guang had no choice but to say, "What if we don't have enough manpower? Not everyone can master Gong Shujia's craftsmanship."

Liu Tan chuckled twice: "I've thought about this. Just build an assembly line. No skills are needed!"

Huo Guang heard a new term, and by now he was used to it, so he asked directly, "What is an assembly line?"

Liu Tan explained, "It's a specialized production assembly line. Anyway, let me tell you, do you see this sight?"

Huo Guang nodded, and then he watched Liu Tan dismantle all the sights. He then took the parts and said, "When the time comes, I will build workshops based on these parts. Each workshop will specialize in processing a certain type of part. There are strict regulations for these parts. Not only do they have to be exactly the same, but they must be similar. After all these parts are made, there will be another workshop specializing in assembly. They will be responsible for putting these parts together!"

With Huo Guang's intelligence, it was not difficult to understand this meaning. However, it was precisely because of this understanding that he was shocked by Liu Tan's brilliant ideas.
