Isn't it just a needle that makes you get stuck on a wood and float in the water? Cai Yan said.

Then you shake it again, turn the bowl a little, and give it a try!

Cai Yan turned the bowl curiously!

Carry on! No, how can this needle turn back automatically?

Zhang Jiedao: What direction do you think he is pointing towards?

Shimin, is this Sinan? Cai Yan said.

Sinan is not practical, the friction is too great, and it can't be turned. This is simple and practical. What's more important is that you can do as much as you want. A magnet and a few needles are enough. Hahahaha! Zhang Jie laughed!

Shimin, how did you come up with it? Cai Yan said.

Hahahaha, because I'm a genius! How else can you be your husband?

Shimin, what are you doing with this little Sinan?

Zhang Jie said: This is very useful, you won't get lost in a war. Especially for sailing, the sea is busy and you won't get lost with this. Your husband is now mobilizing the power of the whole country and is carrying out a crazy plan. If it can happen, it will change the world.

With the support of Zhang Jie's whole country, there are 100 craftsmen in Jingzhou, and Zhang Jie assigns 10 subordinates to each craftsman, and most of these people are carpenters. In addition, according to carpenters, blacksmiths, etc., nearly 2,000 people, built ten 200-ton ships, in fact, it only took more than a month to build. Just caulking, paint, tung oil, to shabu a few times. It takes time to make sails, tank leak detection, etc.

Zhang Jie received the news that the ship had been built, and immediately prepared to leave, because it was now May, and if the time came, Zhang Jie planned to let them go to sea at the end of June. Go to sea in the summer and cross the Bering Strait to a safe point.

Zhang Jie arranged some things in Luoyang, and then took a few "treasures" from Mengjin to the Yellow River and went straight to Qingzhou.

Zhang Jie loaded ten boats of "treasures", which were made tightly in the past two months.

When Zhang Jie's fleet arrived from the Yellow River to Bohai Bay, it entered Donglaihuang County. Cai He, Yang Hong, Jiang Wan, Lv Xiang and others waited to meet at the Huangxian wharf.

When Zhang Jie saw that the ten boats he had high hopes for had been launched, his mood was much more open, the bow of the ship was very high, and the draft was still exposed. Zhang Jie personally went to the ship to inspect it. Each boat has three sails, the inner deck is divided into three levels, and the cabin is filled with the smell of tung oil.

At the bottom is a freshwater tank, cargo compartment. Zhang Jie felt that the setting was very reasonable, and the center of gravity of the cargo was below the waterline to help the balance of the ship.

Cai He, how is the crew training? Zhang Jie asked.

Cai Hedao: Don't worry, my lord has been practicing at sea for two or three months, and there is no problem going to sea, but the new sea ship has not been operated yet.

Zhang Jie said: Don't worry, this ship has been built. You will be able to train at sea with these ships right away.

But time is of the essence and can only give you ten days to train on a new ship. Because it's going to set sail in the summer. So it's imperative to hurry.

You now gather all the brothers who are going to sea. When I come to the county government of Huang County, I have something to tell them.

Promise!

After a while, the small county government was crowded. Outside the door are guarded by personal soldiers.

Zhang Jie said: Brothers sit down. I have called you today to tell you something important. Actually, you all know that. I have let you practice for so long, that is, I want to go out to the sea once to look for food seeds. You must keep this matter a secret, and you must not tell anyone about it.

Ladies and gentlemen, you will have four hundred men and ten ships to go out to sea together. This time when they went to sea, each person was rewarded with 100 gold, and the brother from Jingzhou had already received 50 gold. The brothers who did not get it at the meeting went to the barracks and each received fifty gold. When they come back from the sea, they will get another fifty gold each.

Brothers, this journey has been very fortunate and dangerous. It is likely to kill you. Whether you come back alive or die, the 100 gold will be sent to your family. Please rest assured of this.

Brothers, the grain we are looking for is more than 20 stone per mu. Everyone knows that many people starve to death every year, and if this food can be found, no one will starve to death in the future. You will go down in history forever.

Everyone listened in disbelief.

Zhang Jiedao: Now I ask again, if there are brothers who are afraid of death, they can leave now. I don't hold you accountable. If you don't leave now, you won't be allowed to leave again, otherwise you will be dealt with by military law.

Zhang Jie waited for a while and no one left, and everyone wanted to take a hundred gold.

Very well, yes, you didn't disappoint me.

From now on, you have to remember every word I say. Because your lives are at stake. It's about whether or not you can find food seeds. Believe in me unconditionally. If you don't believe me, then you probably won't come back. Remember, remember.

Here's what I've said that you've never heard before, but don't ask why. Just believe.

Come on, bring things in.

When Zhou Cang held a large cowhide map and hung it on the county government wall.

Zhang Jie held a pole and said, "Brothers, this is called the world map."

Yes! Everyone stared at the map, in fact, few of these people knew how to read, Zhang Jie only found a few readers and accompanied them. But there is no way, if you go so far, you will definitely die, and it is not clear how much you can live back Zhang Jie, maybe the whole army will be wiped out, and maybe you can live a few back. But try to let these people know where they are, and maybe the fleet is scattered, and it will also allow them to come back.

Zhang Jiedao: You see, this is our current location, this is Dahan, and the north of our Huang County is the Liaodong Peninsula.

This time your destination is South America. ………… This place is called Peru, this is Chile, this is the Andes. These are the places where you are looking for the seeds............

You must first enter the Bering Strait from To-Ying (Japan) to the north-east. Then follow the coastline eastward, enter Alaska, and then follow the coastline further south. Through North America and then to South America.

Keep in mind that if you go north from the east, you have to go northeast, and if you go directly north, you will enter the Kamchas Bend. This would block the peninsula from the east.

Cai Hedao: My lord, judging from your map, why don't you just cross the Pacific Ocean? Isn't that a lot closer?

Zhang Jie smiled: You asked very well, let me tell you why.

Come on, bring the globe in.

Zhou Cang brought another ball made of wood, and Zhang Jie had already drawn a map on the ball.

It was also the first time that the people heard that the earth was round. All curious.

Zhang Jiedao: You see, our earth is actually round, if it is directly crossed, then wait for it to walk on its belly. Because the belly is bulging, it's like going up a hill and then going down. Not only is it not closer, but it is farther away. And going north is like walking on a mountainside. Rather, it's closer.

What's more, you see, there are very few islands in the Pacific Ocean. You have difficulty supplying fresh water, and there may be typhoons, so you are prone to accidents.
