When Zhang Jie saw these people, the craftsmen were basically half-old men. Some don't seem to want to come.

Zhang Jie said: Everyone, I'm Zhang Jie, maybe you've heard of me, I asked people to find you, not to do anything to you. Instead, I will take you to do a big thing, to Luoyang to build a ship.

Come to people, send money.

Promise!

The soldiers carried boxes of gold cakes. Fifty gold per person.

Ancient craftsmen were cheap industries, and these craftsmen usually ate with their mouths, when have they seen so much money!

They were all stunned, and they thought they were serving in the rocking service, but they were going to make a fortune! Fifty gold is a lot of money for them.

Zhang Jie said: Follow me Zhang Jie in the future and make a fortune.

Some daring, said: General, is it really just shipbuilding?

Zhang Jiedao: You are shipbuilders, what can I do if you don't build ships? I don't need you to lead troops to war!

Zhang Jie pointed to the sailor on the other side and said: You can't build a ship, but you can sail a ship, so you just drive a boat.

Ladies and gentlemen, this fifty gold is only a bonus, and when the ship is finished, each person will be given another fifty gold. Wages are not included!

Yes! And fifty gold!

General, I did it, I am willing to go to Luoyang with you, but what kind of ship will I build? How much do you make?

Build a sea ship, and the drawings will be handed over to you when they arrive in Luoyang. Build ten ships first. Zhang Jie said.

An old man said: I have built a ship for half my life, as long as the general gives me a picture, I can build it, not that I brag, there is no ship that I can't build.

Okay, everyone, because you are going to Luoyang, you have to say goodbye to your family, and it is not convenient for you to bring so much money. So I will give each of you a horse, and now you will go back. We'll meet here tomorrow!

But then again, once you get the money, you can't run away!

Yuanfu, bring the horses, everyone, I am waiting for you here.

After a while, everyone took the money and left happily.

My lord, will these people stop coming? Yang Hongdao.

Hehe, Jay believes in them, if you really want to go, let's go! It's just that it was sent by Kuai Cai's family, and I don't think they dare.

The next day, sure enough, all the men came, but only one sailor did not. Cai He also came

Zhang Jie said, General Cai, these sailors will be led by you.

Promise!

The next day, Zhang Jie led everyone and 20,000 troops back to Luoyang.

Zhang Jie left, and Liu Qi also breathed a sigh of relief.

As soon as Zhang Jie returned to Luoyang, he began to study the drawings of sea ships.

Zhang Jie knew the pinnacle of ancient Chinese sea ships. It is Zheng He's Western fleet, and its main ship is called the treasure ship, which adopts the ancient Chinese excellent ship type suitable for ocean navigation - the Fu ship type. It is as tall as a building, with a wide bottom point, high head and tail, head and tail square, with guard plates on both sides, and the cabin is a watertight compartment structure. The bottom tip is conducive to breaking the waves, the draft is deep, the stability is good, safe and comfortable, it is the most advanced sea ship sailing in the South China Sea and the Western Ocean route, and it is also the largest wooden sailing ship in the world in ancient times. Displacement of more than 1,000 tons.

But now the technology of the late Han Dynasty has not yet reached such a high level. But Soochow's building ship has already exceeded the displacement of more than 500 tons.

After many revisions and discussions with craftsmen, Zhang Jie finally drew a picture of a treasure ship. And immediately let the carpenter make the model.

Its treasure ship is very similar to Zheng He's fortune ship, but it is much smaller, and the displacement is estimated by Zhang Jie to be about 200 tons. Kind of like the later Caribbean pirate ship. Mainly to resist wind and waves. The bottom is all watertight.

Sailing is not about the bigger the ship, the better. The big ship needs power, and the more people it needs. It is not flexible, and it is easy to run aground when encountering reefs. Columbus crossed the Atlantic, and Magellan sailed around the world. The boats used are not large. There aren't many people either. All are sailboats with a displacement of about 100 tons.

When Zhang Jie handed over the drawings to the craftsman Lao Cheng Tou, Lao Cheng Tou said: Lord, this ship is not difficult, it is much easier than the building boat, but why does this ship make the bottom of the ship deep? Why not flat?

This is mainly to increase the draught. It facilitates the stability of the hull. Because of this ship's strings. It is a little higher than a river boat and can withstand stronger winds and waves. Zhang Jie said.

I see. The lord can rest assured, as long as the materials are enough. These ten ships can be completed in two or three months. Old man Cheng said.

Zhang Jie said: You have 100 craftsmen, and I will assign 10 people to each of you. Be sure to grasp the quality.

Promise!

You will take a ship tomorrow and set off to Donglai, where the ship will go to sea, so the shipbuilding will be in Donglai Huang County (later Yantai). I've got all the materials for you. Tell Yang Hong what you want.

Promise!

Zhang Jie called Yang Hong and said: Zhong Ming, your shipbuilding in Huangxian is extraordinary, and you must control the quality. Treat the craftsmen, they give what they want. Recruit some carpenters in Qingzhou to give them a hand. Mobilize the whole country to support them. Strive to build it as soon as possible.

Promise!

Cai He, you take the sailors to Huangxian County, step up training at sea, and recruit another 300 sailors in Qingzhou. After the ship is built, before going to sea, Jie will personally come to Huangxian to see you off, and will give you a nautical chart. and navigator!

Promise!

What is a navigator? Cai He asked.

Don't ask about that, you'll know then.

Promise!

The next day, all the craftsmen boarded the boat at the Mengjin ferry port in Luoyang and headed for Huang County, Qingzhou.

Come on, call Tian Feng over, No!

Yuan Hao, you know where there is a magnet. The stronger the magnetism, the better!

Tian Fengdao: Magnets can be encountered occasionally. What does the lord want to do with this? Is it to be Sinan? But Sinan is not practical and often fails. I advise the lord not to look for it.

Zhang Jie smiled, you will know later, you can find me a magnet first.

Promise!

In fact, the Spring and Autumn Period. Sinan had it, but the compass was invented in the Song Dynasty.

The next day, Tian Feng brought a magnet. Zhang Jie tried the magnetic force, it should be a natural magnet, and the suction power is not as good as the synthetic magnets of later generations. But letting the compass turn should do the trick.

Yan'er, do you have an embroidery needle here? A little longer of the kind. Zhang Jie asked.

What are you going to do with an embroidery needle? Do you want to embroider? Cai Yan said.

Hehe, Jie's embroidery is the country. Give me a few needles!

Zhang Jie took the embroidery needle and rubbed it on the magnetite stone for a while, and the embroidery needle immediately became a magnetic needle.

I found another piece of cork and cut a little bit of cork with a knife, in fact, the best plastic foam in later generations. High grain poles in the countryside are also OK.

Insert the embroidery needle through the cork so that the cork gets stuck between the embroidery needles. The tips of the needles are exposed at both ends.

Pour a bowl of water and place the needle square in the water, the buoyancy of the cork allows the embroidery needle to float on the water. I saw the end of the embroidery needle pointing north. The end of the needle nose is facing south. Zhang Jie turned the bowl a few times, and the tip of the embroidery needle was always facing the north.

Hahahaha! Zhang Jie laughed, he didn't expect that the games he learned in elementary school would come in handy in ancient times.

What are you laughing at? Cai Yan asked.

Yan'er, come and see what's different in this bowl. Zhang Jie said with a smile.
