I was a fan in ancient times [Transmigration Book]

Han Yi looked at the memorial and fell into deep thought.

He had also thought about this issue before, and the biggest problem in building the Great Wall was actually here, but before he felt that it would take a while for the track to be laid and all the design plans to be completed.

During this period of time, it is enough for Gewuyuan to study it, such as the pulley block.

It's just that he didn't expect things to develop so unexpectedly. With the money from those businessmen, the progress of the Great Wall has been accelerated a lot.

Among other things, the track laying speed from Xianyang to the main towns is not slow.

This is thanks to the fact that it is winter, and most people have nothing to do. They go to lay the track and take care of the food. The food is not bad, so there are many people participating.

In fact, Han Yi originally wanted to give wages, but corvee service is an inherent regulation of this era, and even if he wants to abolish it, he has to do it a little bit.

So in the end he had to strictly order that the food must be enough!

You can’t ask for meat and vegetables, and even broth can only be rewarded according to the progress of the work. After all, the national strength is not enough. Although there are large-scale breeding, but compared to the speed of regular customers on the table in later generations, This era is too far behind.

However, Han Yi is not in a hurry, first solve the problem of food and clothing, and then talk about other things.

The track laying was in full swing, and Han Yi pinched his fingers and calculated that the conveyor network could be laid almost in a year at most.

Because when choosing the location of the quarry before, the principle of proximity has been chosen.

Han Yi thought for a while and decided to call Liu Heng over.

I haven't seen you for a while, Liu Heng seems to have a little less hair, and the hairline has also moved back.

Now it is different from the later generations. If only the hairline is moved back in the later generations, bangs can be left to cover it. The hairstyle of this year is completely exposed, which is really clear at a glance.

Han Yi looked at Liu Heng's slightly haggard look and said with emotion: "It's really hard work for you."

Liu Heng said hastily: "The Son of Heaven has broken down, it's all the job of a subordinate, it's just that the subordinate is dull..."

Han Yi waved his hand and said, "You don't have to belittle yourself. If you are really a dull person, Mo Wanji will not let you take charge of Gewuyuan."

Liu Heng was very ashamed and said: "The lower officials are more than enough to guard the city, but they can't do anything else. If Dean Mo is here, you don't have to bother the emperor with these trivial matters."

Han Yi smiled and said: "He can't solve this problem even if he is here, you can take this back and see if you can solve it."

After Liu Heng took it over, he was a little dazed when he saw the large and small round wheels on it: "What is this?"

Han Yi said: "The pulley block, I have written all the main points on it, you can try to make it first."

Liu Heng asked curiously: "Can this solve the problem of stone transportation?"

Han Yi stroked his chin and said, "I'm not sure, but there should be hope. Even if it can't be used here, it can be used elsewhere. Let's get it out first."

Liu Heng thought so too, anyway, he can do whatever the emperor asks him to do.

Liu Heng's hands and feet are also very fast, and the pulley block is actually not difficult, but even such a small thing actually reflects the development of science and technology.

For example, the bearings and pulleys in the middle don’t just have to be shaped, they have to be able to bear weight.

Especially if you want to hang it up the mountain, there are more load-bearing places.

Liu Heng experimented for a long time. With the current technology, it can bear the load, but the problem is that the loss is also very large.

With the scale of the Great Wall, I am afraid that the pulley block consumed will cost you a lot of money.

"Actually, that's not the most important thing..." Liu Heng carefully glanced at the serious Han Yi and whispered, "If you're not afraid of [-], you're just in case, if it breaks when you hang yourself on the mountain...then... ..."

That's a disaster. How many people will die if the stone rolls down the road?

Han Yi frowned: "In this case, it is indeed inconvenient to use stones, why not..."

Liu Heng lifted his spirits: "What?"

However, what disappointed him was that Han Yi shook his head and said, "It's nothing. The pulley block is not useless, but it can't be used in this way. Give him a different form."

Liu Heng swallowed the previous question: "What form?"

Han Yi said: "Cableway!"

After being at a loss for a moment, Liu Heng immediately asked: "Is the emperor talking about Xuandu?"

Han Yi was a little surprised: "Yes, you also know?"

Liu Heng smiled and said, "I have seen you at the ferry before."

Han Yi suddenly realized that things like ziplines have existed for a long time, but they are usually used when going from high to low or crossing a river, and it is not easy to go from low to high.

But those are very simple two ropeways, either relying on inertia or manpower, so it still needs to be improved.

Han Yi nodded: "Since you know, let's design it first. I'll go back and think about it and see if I can solve it."

Liu Heng didn't say anything, Gewuyuan is doing this kind of thing, if everything can be invented by the emperor, then what's the use of them?

It was a pity that Han Yi was on the way back. He thought of cement just now.

Han Yi actually doesn't remember the cement formula, but it's not that difficult to experiment with it.

However, cement cannot be used as the main material of the Great Wall. The latter said that for cement to be the main material, it must have a strong enough "skeleton", which is the legendary steel bar.

It's just that with the current metal smelting technology... let's forget it.

Of course, firing bricks is also an option, but here comes the problem—the production capacity cannot keep up.

How many bricks are really needed to build the Great Wall? With the current production capacity, I am afraid that the Great Wall may not be able to be built when Fusu is buried in the ground. What's more, Han Yi can only provide an idea in terms of burning bricks. Experiment a little.

So no matter where you look at it, using stone is the most time-saving and labor-saving way at present.

However... cement can still be used. After all, even if it cannot be used as the main body, it is still a very useful gel material. It is also good to use it to bond stones.

Even if cement is produced, it is likely to have an impact on the existing construction industry. If the amount of cement is large and cheap, only the royal family's money will be able to continue to generate energy.

Thinking of this, Han Yi couldn't help sighing, and Yan Zheng who was on the side asked, "Why are you unhappy? Tell me, and I will solve it."

Well, what is it that makes you unhappy with Han Yi now?Say, let me solve it; who made you unhappy?Said, I did him!

This was so unreasonable that Han Yi often couldn't laugh or cry.

At this moment, Han Yi couldn't help but smiled after hearing his words and said, "It's nothing, I'm just thinking about how to make money."

Yan Zheng paused, put the pen aside and said helplessly: "It seems that I made you unhappy."

Han Yi:? ? ? ?

How did you come to this conclusion?

Yan Zheng also sighed and said, "Don't think so much, I'm not that poor, and you shouldn't be too tired."

Yan Zheng is really helpless, if he also calls himself poor, then there are probably no rich people in this world.

Not to mention the things that Han Yi did, but Yan Zheng himself has a lot of property, and the land and manor are not so descriptive.

After all, he is the king of a country.

Han Yi said: "It's not poor, but no one dislikes having a lot of money. Seeing the construction of the palace this time, we can build it if we have money and want to build it, and we don't have to listen to those people talking about it. Isn't it good?"

Yan Zheng couldn't help laughing: "It's only one time to build an imperial palace. In the future, it will be repaired at most. Even the construction of the palace cannot cost so much."

Han Yixin said that you can forget it, it's fine now, and you will go out for a stroll after a few years when the court situation is stable.

However, Han Yi still understands him quite well. How could he not be willing to walk around and take a look at such a large area of ​​land after he conquered it?

But this tour will cost a lot of money, the emperor goes on tour, can it be ordinary people's tour?

How many palaces are there to stay along the way? Forget it. The emperor's tour is very grand. Han Yi reckons that he will have to add himself this time. There will be more people, and the consumption of so many people will be astronomical.

Han Yi has already started saving money for Yan Zheng's trip.

He does not hope that future generations will only judge Yan Zheng's trip as a waste of time and money.

Yan Zheng didn't know what he was thinking, but he just persuaded: "You and I are sitting on the world, and it's basically the people of the world supporting a family, why do you bother so much?"

Han Yi thought about it for a while, and it is not the same as the future generations. It is not too much to say that the world supports a family.

He said helplessly: "Actually, I didn't worry about it. I just came up with an idea and thought that I might be able to make a lot of money. However, the process in the middle is a bit complicated."

Yan Zheng said indifferently: "If you bother too much, don't do it, or leave it to the people below. You...you should have a good rest, you are busier than me every day!"

Hearing that his tone was a bit wrong, Han Yi couldn't help but glared at him and said, "I'm busy and I don't have time to spend with you."

Yan Zheng came over with a smile and said, "Why don't we go earlier tonight..."

Han Yi calmly pushed his big head away and said, "Restrain yourself, my leg hurts!"

Compared with Yan Zheng, his physical strength is really not that good. Every time the clouds and rain rest for a while, Han Yi can't help but reflect on this situation. He is more worried about himself than Yan Zheng!

However, what Han Yi was worried about was not the issue of cement, but the issue of patents.

Cement is very simple to say, at least the formula that can be made now is very simple.

Of course, no one dares to intervene in the royal business, but if there are patents, patents can make money. Once driven by interests, perhaps the problem of too few people in the world to study Gewu can be solved.

Even if it can't be completely solved, it can still make people who are originally interested but struggling to make ends meet find a way forward.

It's just that in this era...it seems a bit difficult to talk about patents.

Even if he came up with a patented concept, it would be difficult to maintain it.

Because communication is not well-developed, people may not even know that they have violated their rights.

This... how to do it?
