Time flies, and in the blink of an eye, it is the fifteenth day of the first lunar month.

Li Yuanjing took over the talisman from Li Shimin, which also meant that the two thousand sailors were completely handed over to Li Yuanjing, at least during this trip, they belonged to Li Yuanjing's army.

As for the palace guards, Li Yuanjing only left a hundred people, and the other more than 600 people traveled with Li Yuanjing.

At this point, there were more than 2,600 people in the official army, and with the security that the other three little guys carried with them, they could barely scrape together 3,000 combat strength.

It is not strong to say strong, and it is not weak to say weak.

On the nineteenth day of the first month, a group of thousands of people came to Luoyang, the eastern capital, where they transferred to boats, went south through the Grand Canal, and went east to Yangzhou and Yanjiang waterway, and saw their own fleet and 2,000 sailors at the mouth of the sea.

declined the banquet invitation of the governor of Yangzhou, counted the manpower, and the group boarded the ship directly.

The huge fleet of fifteen thousand-stone cargo ships, five thousand-stone troop carriers, and five five-hundred-stone troop carriers attracted the attention of the surrounding people for a while.

"Mother...... I can't see the edge at a glance......" Standing at the top of the troop carrier, looking at the endless sea, Cheng Chuliang was shocked.

"The world is so big, it's really strange...... "The eldest grandson is not much better, he really can't understand, why is there so much water all of a sudden?

"Calm down, calm down, you will be shocked in the future!" Fang Yiai was very calm, but his legs were trembling, and he was a little seasick......

Compared with the three little brothers who have never seen the world, Li Yuanjing at this time is not so easy.

Since the fleet has no experience in going to sea, even if they are now on a thousand-stone sea ship, they still have no bottom about going to sea.

Li Yuanjing knew the danger on the sea, and he also knew that now that the wind and waves were calm, there was no danger at all.

No, the biggest danger they face now is running aground.

However, there is no way to do this, the fleet does not dare to leave the sight of the mainland, once the course deviates, it must be repaired immediately, and it is necessary to ensure that the lookouts on these twenty thousand-stone ships can see the continental shelf at any time, so as to ensure that they will not run away.

However, this means that they can only sail in the near continental area, and this route is the most dangerous, the water is not deep enough, and the slightest carelessness can run aground.

Of course, the danger is not as great as imagined, the main reason is that their current power is completely solved by manual rowing, and the speed is not fast at all, and they can't even see a sail battleship in these years.

"It's okay to draw nautical charts, right?" Li Yuanjing came to the deck and asked several officials who were busy.

This is what Li Yuanjing specially asked Li Shimin to want, their daily task is to draw a map of the Tang Dynasty, that is, those maps that are so rough that they can't be rougher, looking at this kind of map can at most allow you to ensure that the general direction is not biased, and if you want to find the destination accurately, forget it, it is not reliable at all.

The main thing is that there is no modern equipment to rely on, and it is already good to be able to draw the location of each town, so what else can you expect?

This time, Li Yuanjing directly asked for ten people, and installed Sinan on each ship, that is, the compass, after so many years of development, unless it is a change in the magnetic field, it will not be too much of a problem.

"Your Highness, rest assured, in fact, it is not difficult to draw nautical charts, as long as we can get the information on land." Ren Zhixing said lightly, and didn't seem to feel any difficulty in this task at all.

He was admitted through the imperial examination during the Wude period, and because he had no backstage, he was only a member of the second list, so he was in charge of this kind of bitter and thankless yamen, who could not see the hope of promotion, and did this desperate job.

This time, Li Yuanjing asked for someone, and almost all the people in the yamen walked all over again, not begging grandpa to tell grandma to follow, but begging not to take him away, it's so bitter......

But Ren Zhixing doesn't think so, his career is like this, if there is no big opportunity, this life will be like this.

After decades of hard study, his family background was emptied, and he finally got into the fame and became a civil servant.

"Well, if you can do a good job this time, the king of the promotion is not guaranteed, but it is certain to make a fortune!" Li Yuanjing gently patted Ren Zhixing, who was nearly twenty years older than him, and said with an old-fashioned look.

"Your Royal Highness, in fact, this trip to Goguryeo, it is the closest to go to sea from Langxi, and when Xu Fu gathered into Qin, he went to sea from Langya, passed through Goguryeo and other countries, and finally arrived in the Wa Kingdom." Ren Zhixing was overjoyed and hurriedly added.

Familiar with the geography of various places, this may be his only chance.

And it is impossible for His Royal Highness King Zhao to stay with him every day to understand these geographical conditions, Ren Zhixing quickly judged that there are not many opportunities to contact His Royal Highness so closely, so he quickly sold his knowledge with his heart with careful thought, hoping to be appreciated by King Zhao.

"Going to sea is not as simple as you think, you will know later!" Li Yuanjing smiled slightly, the other party was just a small person, of course he didn't need to explain so much to him.

If he could, Li Yuanjing didn't want to go to sea from the mouth of the Yangtze River, but the Yangzhou branch was the closest place to the sea, plus this is the production area of silk, all kinds of good goods can be found, if you go to sea from Langya, the distance is close, but he has to hire a large number of people to transport these dozens of ships of goods to Langya, how much manpower and material resources will be spent in the middle?

Ren Zhixing saw that Li Yuanjing was not interested in his suggestion, or that his suggestion was not yet attractive, but Ren Zhixing was not disappointed in his heart, although he did not succeed this time, as long as he could draw the chart well, this credit was still not small.

The fleet continued to move north, as slow as a turtle, and it was not easy to rely on artificial oars to propel a thousand-stone cargo ship full of goods to sail, but it was better when the wind was calm, but if there was a bit of a headwind, the fleet had to use more strength to ensure that the ship was not blown away, let alone forward.

"Why did you get out?" Looking at Cheng Chuliang, who was suddenly standing beside him, Li Yuanjing set his eyes in the distance, on the endless sea.

"They're so disgusting...... Cheng Chuliang pointed to the inside of the cabin with an embarrassed face, but with the bump of the hull, the whole person seemed to be unable to control it anymore.

'Vomit ......'

However, he also understood what Cheng Chuliang was referring to nausea, and it was estimated that the smell in the cabin must be very exciting, and before sailing, many people heard that it was difficult to eat hot meals at sea, so they rushed to eat themselves until they couldn't walk, which would react, and of course they reacted the most.

Li Yuanjing looked at Cheng Chuliang speechlessly, and secretly said You are not disgusting, it is all dry.

"Your Highness, why are you alright?" After vomiting, Cheng Chuliang felt a little better in his heart, and looked at Li Yuanjing, who had no reaction at all, and couldn't help but be curious.

"People are different from each other......"

This sentence was withdrawn, and Li Yuanjing regretted it that afternoon!
