The sea breeze filled the sails, and a large ship was moving forward quickly. The waves hit the bow of the ship and were immediately smashed to pieces, floating one or two meters high, making a rustling sound.

Behind this big ship was followed by dozens of big ships with sails raised, closely following behind the flagship.

At the bow of the flagship ship, Jiang Hao stood on the deck of the ship, holding a tool in his hand, observing the sea in the distance.

Ji Bu looked at the strange tool he was holding curiously, and watched the lord come over and tinker with it. From time to time, Ji Bu couldn't help but ask curiously: "Master, what are you doing?"

"By using the sextant, measure where we are now to determine whether the fleet has gone off the line." Jiang Hao said.

"You can know where we are with this little thing, but I see that there is a vast ocean around me, so how can you tell the difference?" Ji Bu asked curiously.

"Simply put, I use the tool in my hand to measure the angle between the sun, stars and sea level, and then calculate the latitude and longitude, so that we can know where we are."

"Of course, it is useless to just measure the angle. You also need to know what the position of the sun is at the time, what the stars are at the day, and remember the position of the world's latitude and longitude. By using a calculation formula, you can calculate the location of our ship."

Ji Bu swallowed quietly.

Or simply put it.

It's really hard to be a poor student.

"Don't look at this little thing, it took me a lot of effort. But I let the craftsman do it for a long time to get it out. It's okay to polish it. The main reason is that it's so transparent and without any flaws is hard to find. Fortunately, I made it out, and I specially made one more telescope." Jiang Hao said with a smile.

Ji Bu still didn't understand and grinned awkwardly.

Jiang Hao saw Ji Bu smirking, took out a brass tube from his sleeve, pulled it out and looked out, and handed it to Ji Bu, "Look at it like I just did." Ji Bu took the telescope and imitated Jiang Hao to look out, and was shocked by the scene in front of him.

"Wow~~ I can see so far." Ji Bu shouted.

"With this, you can see a farther place. If there is a naval battle, this thing will have a greater effect. Now, I guess I can only look far away, look for land, be a toy or something." Jiang Hao said.

Sextant is very important to the ocean. After the sextant was invented, it played a huge role in the development of the navigation industry. Even in modern society, there is a satellite positioning system on the ship, but it will still be equipped with a sextant as an emergency.

Jiang Hao has a full world map in his mind. As long as he determines where he is, he will not get lost at sea.

This time, Jiang Hao brought all 30 ships to sea, and also brought Ji Bu's 1,000 guards. Now his guards are all equipped with all soldiers with horseshoes, stirrups, crossbows, spears and swords.

This time, we not only came to pick up Yu Shu, but also an experiment. We can experiment with how they sailed on the sea. We finally feel that it is shallow on paper. Only when we get to reality can we test how many problems we will encounter and prepare for future voyages.

Haicheng is not far from Goguryeo. The fleet crossed the Yellow Sea. After driving on the sea for 4 days, he finally saw the land. Jiang Hao measured the location and said, "Continue to drive along the coastline. You should be able to reach Longchuan in less than a hundred miles away."

In the afternoon, the fleet drove into a bay, which was Longchuan, a small port city in Goguryeo, with a population of less than a thousand people.

The fleet occupied the port terminal directly, and Ji Bu took the lead and occupied the terminal. The fishermen and merchant ships on the terminal were frightened and hid beside them and shivered. They didn't know where these people wearing armor and driving huge warships came from.

The deck was set up, and the war horses came down, and more soldiers came down. Many people here were so scared that they ran away. Finally, a middle-aged man wearing a Goguryeo official robe appeared, with three strokes of goat beards and trembling.

"May I ask, are you the heavenly soldiers of the Great Qin Empire?" The official said in a trembling voice.

Ji Bu looked at him and said, "We are the guards of the Great Qin National Master. We are here to pick up Princess Goguryeo Yushu."

When the official heard that it was not a war, he came to pick up the princess, and his expression suddenly relaxed a lot.

"I am the magistrate of Longchuan County. If you have any needs, please raise it." said the magistrate of Goathu County.

"Since you said that, you're welcome. Our big ship is going to stop here. You don't have to care about the food. I guess you can't afford it. If they need fresh water, find someone to take them to the place to get water."

There were 30 large ships, and there were 30 or 50 sailors running on each ship, with a total of no less than a thousand people. These people were not good at all. Jiang Hao also sent them a long bow, arrow, spear, and let them participate in combat training. However, these sailors were not a problem to go to Southeast Asia to eliminate a small country.

"Also, for this thousand of us guards, we need a place to rest, which is bigger. Also, prepare a suitable house for the National Normal University to rest."

The county magistrate was shocked when he heard this, "Ah, is the Grand Master of the Qin Dynasty here too?"

"It's on the boat." Ji Preached.

The county magistrate was worried and said with a bitter face, "But, our place is poor and there is no house that can match the status of the National Master."

"Whatever is what you have is," Ji Preached.

The county magistrate immediately nodded, "Okay, okay, I will definitely use the best manor to entertain the National Normal University."

"Also," Ji Bu said at last: "Send someone to inform the King of Goguryeo, and say that the Master of the Great Qin State came to pick up Princess Yushu and asked him to prepare early."

The county magistrate immediately bent down, "I will send someone to notify the king."

When Jiang Hao got off the boat, the goatee county magistrate immediately knelt down to greet Jiang Hao. In this era, the Qin Dynasty was originally a superior country, and the status of the Qin army was no less than that of the King of Goguryeo, so the county magistrate naturally had to kneel down.

Then the county magistrate led everyone to a manor in the city to rest, and Jiang Hao realized that this manor belonged to the county magistrate.

Listening to the county magistrate's fluent speech of Zhongyuan, Jiang Hao thought a lot in his mind for a moment.

Speaking of which, the Koreans during the Qin Dynasty were all Chinese.

Before traveling through time, he had read a lot of history about the Qin Dynasty. Because of Yu Shu, he naturally also read an introduction about Goguryeo. If it were historically speaking, the movies were all wrong.

During this period of the Qin Dynasty, the Goguryeo did not exist on the Korean Peninsula, and it should be called the Jizi Dynasty.

Jizi, the founder of the Jizi Dynasty, was the uncle of King Zhou of Shang. After King Wu defeated Zhou, Jizi brought 5,000 people here to establish the Jizi Dynasty and established the capital of Ping (Rang) City. It was called Jizi Korea in history.

During the Warring States Period, the Jizi Dynasty was always under the jurisdiction of Yan. Later, Qin destroyed the six kingdoms and the Jizi Dynasty surrendered to the Qin Dynasty. However, the Qin Dynasty only lasted for 14 years and then collapsed. The Chu-Han and Han struggled, and all regions became kings. Later, during the War of Unification, Liu Bang destroyed the Yan Kingdom. Wei Man, a native of Yan, ran away with more than a thousand people, ran to Pingcheng, and directly destroyed the Jizi Korea.

It’s not a joke, but historical records are that they are carrying more than a thousand people. Of course, there are sneak attacks on the government. After all, Jizi North Korea was also a country with more than 100,000 people. The defenders established their own country, known in history as the Wei Dynasty. However, after about ninety years, it was destroyed by Emperor Wu of Han and then divided the peninsula into four counties.

The Korean Peninsula during the Qin Dynasty should still exist in the form of a tribal alliance in Jizi and North Korea.

As for Goguryeo, it was the most powerful country on the Korean Peninsula established in the Eastern Han Dynasty. It was established by the Fuyu people in Changchun. The screenwriter used the name Goguryeo, probably to save trouble.

And why it is not called North Korea, it is probably because it is afraid of things.

Jiang Hao shook his head gently, knowing that he had traveled to the world of movies, so why bother with history? If all follow history, then he should not exist. Qin Shihuang should have rotted and smelly now, and was on the way to Xianyang, and Fusu had already committed suicide.

As for Goguryeo, what are you worried about? According to the setting here, Goguryeo is a vassal state of the Qin Dynasty, a multi-ethnic tribal alliance country, and the current king is Yushu's father.

Anyway, she came to pick up Yu Shu. After getting Yu Shu, Jiang Hao had to consider not her country, but how to complete the requirements of the system tasks.

What are the system tasks?

"The customer wants to see Yushu have a perfect ending."

What is the perfect ending? Jiang Hao can't figure it out now.

Marry her?

Make her feel happy?

Give her a child?

Or if she falls in love with someone else, she will give it to others generously. But~~~! She will probably be sprayed to death. Those readers are so cruel that we dare not mess with them.

Sometimes open tasks are troublesome, without quantitative standards, like the system records how many treasures are stolen and how many people are killed, but in fact, such tasks are easier to do.

Longchuan Port is about 100 miles away from the Pingcheng of the Goguryeo capital. Jiang Hao did not take any further action and had sent someone to notify him. He just waited for the other party to reply and saw what arrangements the King of Goguryeo had. Jiang Hao and the others waited for two days and finally waited for a reply.

The King of Goguryeo personally replied, and the text in the letter was filled with enthusiasm, warmly welcomed the Grand Qin National Master. He had already set off with Yu Shu and came to Longchuan Port to welcome the National Master to the capital.

Jiang Hao put down the letter and looked at the official who delivered the letter. This official from Goguryeo was here to welcome Jiang Hao and make preparations in advance.

"Do you know the route of King Goguryeo?" Jiang Hao asked.

"The little one knows that there is only one big road." The official said.

"Welcome to the king, why do Jiang Hao have the nerve to wait here? Let's set off now and go against King Goguryeo, so that we will meet faster." Jiang Hao said.

The official dared not stop it, "It is up to the National Normal University to decide, and we will obey it."

Jiang Hao's team gathered, and a thousand cavalry headed towards the Goguryeo Royal City, but he didn't know that someone had already set his sights on their team, and the goshawks kept flying up and heading north. After flying more than a hundred miles away, a team appeared under the goshawks. The team had a large number of people, and the number should be less than two or three thousand people. They rode on horses and held weapons in hand, showing a fierce look on their faces.

The goshawk fell, and a man in his thirties and wearing armor raised his hand, and the goshawk landed on his arm. The man took off the letter from the goshawk's claws, shook it open and looked, his eyes becoming colder.

"Yu Shu is mine, no one can steal her, nor can Daqin's national teacher."

"If I fail to act, if I do not take action, what kind of face should I have to be the leader of the tribe? If I want to be a king in the future, who else will believe me?"

"Kill, kill, kill!"

The man shouted three words "kill" in a row, and the soldiers behind him also raised their hands and shouted loudly.

"Kill and kill! Kill and kill!"
Chapter completed!
