Building an iron-clad ship was really not as simple as Li Yao imagined, and it didn't take a few days for the craftsman's team to build an ironclad ship weighing 5,000 catties, and finally got the boat into the water and sank it directly!

Seeing this situation, Li Yao hurriedly said, "Quickly fish out the iron boat!" ”

Seeing that the experiment had failed, the craftsman king said, "Yao'er, it's really difficult for the ironclad ship to float on the water!" ”

Li Yao shook his head and said, "Grandpa, the ironclad boat must be able to float on the water, give me two days, I'm calculating, and then we're experimenting once!" ”

The craftsman said: "Yao'er, don't worry, you calculate slowly, it turns out that I failed many times when I built artillery, and I didn't succeed in the future!" ”

Li Yao thought for a moment and said, "Grandpa, you send someone to dig a big pit fifty steps long and fifty steps wide for me, dig three steps deep, and then fill it with water, and fill it with water one step deep!" ”

When the craftsman heard Li Yao's strange request, he asked, "Yao'er, what are we digging this pit for?" ”

Li Yao said: "Grandpa, you just do what I say, some things can't be explained for a while!" ”

The craftsman nodded and said, "Okay, I'll ask the craftsman to get it!" ”

Li Yao wants to use displacement to roughly estimate the weight of the iron ship, the density of iron is nearly eight times that of water, if you want the iron ship to float on the water, that pound of iron must be able to drain eight pounds of water, in later generations are used to measure the weight of the ship, such as a displacement of 10,000 tons, then the weight of the ship plus the things on the ship can not exceed more than 1,000 tons at most!

One step is about 1.5 meters, that is converted to 75 meters long, 75 meters wide, 1.5 meters deep, then the weight of the water should be 170,000 catties, according to the theory of eight to one, if the iron boat wants to float on the water, the weight of iron must not exceed 20,000 catties, and the displacement must be the height of the water to two steps deep!

Because there are so many laborers in Firearms City, digging a pit is easy!

It only took three days for the big pit to be dug, Li Yao said to the craftsman: "Grandpa, it's actually very simple to build an ironclad ship, you see the height of the big pit, the current water volume is one step deep, we can only use no more than 20,000 catties of iron to build a ship, and then put the boat down, the height of the water surface can not be less than two steps, as long as these two conditions are met, I can ensure that the ironclad ship can float!" ”

The craftsman said: "Yao'er, this is obviously impossible, if you want to make the height of the water surface not less than two steps, at least a hundred thousand catties of water, you let me use no more than 20,000 catties of iron to raise the water surface to two steps high, this is obviously impossible!" ”

Li Yao said with a smile: "Grandpa, the shipbuilders will come over tomorrow, you are going back to think about it, see if there is a way to complete this task, if you really can't think of it, let's think about it with the shipbuilders tomorrow!" ”

The craftsman nodded and said, "Okay, then I'll go back and think about it!" ”

On the second day, the fat man came with hundreds of shipbuilders, including a few masters! This made Li Yao very satisfied!

Li Yao found the craftsman king and asked, "Grandpa, have you come up with any solution?" ”

"If you make iron in the shape of a boat, you may be able to float on the water, but I'm not sure how big a boat you have to make!" ”

Li Yao called the master of the shipbuilder and asked, "Have you ever built an ironclad ship?" ”

The shipbuilders shook their heads and said, "Iron is so much heavier than water, how can it be used to build ships?" ”

Li Yao took a few people to the side of the big pool and said: "One of you is a unique craftsman king in the world, and the other is a shipbuilding master who has been immersed in it for many years, you discuss it, I ask you to use no more than 20,000 catties of iron to raise the height of the water surface of the pool to a depth of two steps!" ”

The shipbuilder hurriedly said: "My lord, I am a shipbuilder, and I don't know immortal arts, how can I use 20,000 catties of iron to raise the water surface one step higher!" If you want me to see, without a million catties of iron, it is difficult to fill the water surface to a depth of two steps! ”

Li Yao said: "If it is all filled with iron, what else do I want you shipbuilders to do, anyway, I will give you ten days at most, and build a boat for me with 20,000 catties of iron, don't care if you can raise the water in the puddle to two steps, and build the boat first, it's not difficult!" ”

The king craftsman and the shipbuilder both nodded and said, "It is not difficult to build a ship with 20,000 catties of iron, if we have enough manpower, we will definitely be able to build it within ten days!" ”

Li Yao said: "The boat doesn't need to be built too finely, just build a frame, and the sealing must be good!" ”

The shipbuilder nodded and said, "My lord, you can rest assured, I have built a ship all my life, and I have never built a leaky ship!" ”

Li Yao nodded and said, "That's good, by the way, you just need to build a flat-bottomed boat, remember that the height of the boat cannot be higher than two steps!" ”

The shipbuilder nodded and said, "That's no problem, my lord, I can build you any style of ship you want!" ”

Li Yao nodded and said, "That's good, if you are busy in the future, let's go to build a ship first!" ”

Ten days later, a flat-bottomed ironclad ship was built, and Li Yao said, "Put the boat down the water and see!" ”

When the boat was put into the water, the water level was still one foot away from rising to two steps, Li Yao said: "Fish out the boat, you still use so much iron, but when you build the wall, make it a third thinner!" ”

The craftsman king said: "Yao'er, if you modify it like this, this ship will be too thin!" ”

Li Yao said: "It's okay, you can build it!" ”

The craftsman king nodded and said, "Okay then, I'll start the craftsman manufacturing!" ”

Ten days later, the thin ironclad boat was built, Li Yao asked people to put the iron boat down, to see the effect, when the iron boat was finished, the water level had exceeded two steps deep, Li Yao knew that it was successful!

Li Yao said: "Send a few people to go into the water to take a look and see if the boat is floating on the water!" ”

The shipbuilder hurriedly said, "My lord, I'll go down and have a look!" ”

Then he took off his coat and shoes, and a fierce man plunged into it, and after the tea time, the boatman came out of the water and shouted, "My lord, the iron ship has really floated!" ”

Li Yao looked at the craftsman king and said, "Grandpa, let me say, iron can float on the water!" ”

The craftsman was also surprised, then took off his clothes and said, "I'm going to go into the water to see it myself!" ”

Li Yao said to the guards behind him: "Protect grandpa from entering the water, don't let the craftsman king be harmed!" ”

The guard nodded, "Yes!" ”

The guards accompanied the craftsman king into the water for a turn, and when the craftsman king came out, he said excitedly: "Yao'er, the ironclad boat is really floating on the water!" ”

Li Yao nodded and said, "Grandpa, with this ironclad ship, our future naval army will really be close to invincible!" ”

But the craftsman king was not very optimistic, and said: "Yao'er, although the ironclad ship floats on the water, it is too thin, if it really collides with the wooden ship, I am afraid it is not particularly advantageous!" ”

Li Yao said with a smile: "Grandpa, what is a ship of 20,000 catties of iron, at least you have to build a ship of 1 million catties of iron!" ”

The craftsman king exclaimed: "A ship of millions of catties of iron, then the time it took to build this ship is not short!" ”

Li Yao said: "Is half a year enough? ”

The craftsman said: "Yao'er, it took ten days to build a ship of 20,000 catties of iron, and if you build a ship of 1 million catties of iron, I'm afraid half a year is not enough!" ”

Li Yao said: "Grandpa, I will give you all the people and money, you try to build it, if you can't build it in half a year, then it will take a year, anyway, build it as soon as possible!" ”

The craftsman said, "Is the thickness of the wall of the ship still in proportion to the thickness of the wall?" ”

Li Yao shook his head and said: "At least half of it must be reduced, because we are going to put people and weapons on it, so we must shrink it by half!" ”

The craftsman king said: "Yao'er, then we need a good port, otherwise such a big iron ship will not be able to be put in the water!" ”

Li Yao said: "Yiguo has the Yangtze River, you look for it by the river, build a temporary port, and when we take the country of Li, there are many deep-water ports there, let's put the shipbuilding base over there!" ”

The craftsman said: "Okay, I'll look for it, but I'm afraid this hundred shipbuilders are not enough, we still need enough manpower!" ”

Li Yao said: "Grandpa, you can recruit as many people as you like, tell me directly how much you want, and I'll figure out a way!" ”

The craftsman nodded and said, "Okay, I'll take the shipbuilders to find a place to build a port on the edge of the Yangtze River!" ”

Li Yao nodded and said, "Grandpa, then it's hard for you, by the way, how is that hot air balloon made?" ”

King Craftsman said: "I handed over the hot air balloon project to the students of Firearms City, and I think it won't be long before there will be a finished product!" ”

Li Yao nodded and said, "Although the hot air balloon is not as important as the ship, it is our air power, and we still need to pay attention to it!" ”

The craftsman king nodded and said, "You can rest assured, I know this!" ”

Li Yao looked at the time and said: "Grandpa, I have also found a lot of iron ore in Yiguo, and I have 200,000 captives who can mine iron ore, so you don't have to worry about iron resources, no matter how much iron ore is mined, I will send it all to you!" ”

The craftsman king nodded and said, "Then I'll be much more relieved!" ”

Li Yao said again: "As for the money, I will also raise money for you as soon as possible, how can five million taels of silver be enough, at most a month, I will get it for you!" ”

The craftsman king calculated for a moment and said, "Five million taels is enough to build two ships, I will definitely save some flowers!" ”

Li Yao said: "It's okay, no matter how much money we spend now, we will earn it countless times in the future, you can just use it!" ”

When the craftsman heard Li Yao's words, he was immediately relieved and said, "Well, with your words, I can rest assured that I can build a ship!" ”

The next day, Li Yao said goodbye to the craftsman king and returned to Yidu, and when he arrived in Yidu, Li Yao did not go to the palace, but went directly to Anzhu!

An Zhu saw Li Yao coming, and hurriedly greeted him: "Why is Yao'er here?" ”

Li Yao smiled: "I haven't seen you for many days, I miss my father-in-law very much, so come and have a look!" ”

An Zhu said: "Yao'er, you haven't been in Yidu for a month, and your father-in-law's work is very difficult to carry out!" ”

Li Yao asked, "Father-in-law, what's wrong?" Why is the work not carried out? ”

An Zhu said: "It is difficult to collect the tax of merchants now, the commercial tax is twice as high as the agricultural tax, and many businessmen are complaining!" ”

Li Yao said with a smile: "Father-in-law, I thought it was a big deal, isn't it just that the taxes can't come up, father-in-law, you give me the list, and I will let people tell them, it seems that they have forgotten about the tens of thousands of people who died in Yidu more than a month ago!" ”

Hearing Li Yao's words, An Zhu hurriedly said: "Yao'er, in fact, it's not like this, businessmen are profit-seeking, so it's understandable that the tax payment is late, there is no need to kill them all!" ”

Li Yao nodded and said: "Since my father-in-law said so, then I will let them go, and you can tell those who refuse to pay taxes, if you can't see taxes in three days, then don't think about staying in Yiguo!" ”

An Zhu hurriedly nodded and said, "Yes, I'll tell them later!" ”

An Zhu looked at the dust on Li Yao's clothes and asked, "Where did Yao'er come from?" How can there be so much dust on your body! ”

Li Yao said: "I just came from Firearms City, and I didn't even go back to the palace, so I came directly!" ”

An Zhu asked, "What's wrong?" Is there something going on over there in Firearms City? If you need my help, just let me know! ”

When Li Yao heard An Zhu say this, he hurriedly sighed and said, "Father-in-law, when you say this, I am really short of money, and I need money again in Firearms City, and I am shy in my pocket now!" ”

As soon as An Zhu heard that Li Yao needed help, he hurriedly said, "Yao'er, if you need money, just tell me!" ”

Li Yao immediately said: "Father-in-law, then I will say, I need five million taels of silver!" ”

An Zhu thought for a moment and said, "Yao'er, five million taels of silver, I can give it to you!" ”

When Li Yao heard An Zhu so bold, he quickly stood up and said, "Father-in-law, thank you so much!" ”

An Zhu also stood up and said, "Yao'er, it's all a family, why are you so polite!" ”

Li Yao nodded and said, "Father-in-law is right, we are all a family, and I have good news to tell you!" ”

An Zhu asked, "What good news!" ”

Li Yao said: "Father-in-law, in two years at most, I can open up sea routes and dominate the sea!" ”

An Zhu said suspiciously: "Yao'er, the sea is not as good as the land, you can't underestimate it there!" ”

Li Yao smiled: "Father-in-law, don't you still believe what I said?" If I say I can open it up, I can open it up! ”

An Zhu hurriedly said: "Of course I believe Yao'er's words!" ”

Li Yao nodded and said, "Just believe me, when the sea route is opened, I will let your caravan follow and make money from foreign countries!" ”

When An Zhu heard Li Yao say this, he quickly became excited and said, "Is Yao'er serious?" ”

Li Yao smiled: "Father-in-law, when did I tell a lie!" ”

An Zhu said excitedly: "Yao'er, five million taels of silver is not enough, I'm giving you an extra five million taels of silver, hurry up and make a powerful weapon, and then dominate the sea as soon as possible!" ”

Li Yao arched his hand and said, "Then thank you father-in-law!" ”

An Zhu smiled: "It's all within my responsibility, a little money, nothing!" ”

By the way, Li Yao said: "Father-in-law, I will be crowned king in a short time, you will be the ruler of the country by then, do you need to spread this news?" ”

An Zhu thought for a moment and said: "Yao'er, it's best not to spread the matter of my father-in-law now, you also know that the Liang Dynasty has blocked the economy of Yiguo, fortunately, I have some connections, so I can continue to do business in the Liang Dynasty, if others know that I am your father-in-law, then I will really cut off the wealth of the Liang Dynasty!" ”

Li Yao nodded and said, "Okay, then I'll help you keep it secret, and when I defeat the Liang Dynasty, I'll announce it!" ”

An Zhu hurriedly said: "Then it's troublesome Yao'er!" (To be continued.) Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ)
