I am not Song Qinzong

"Here." Fei Bao no longer insisted, turned around and was about to go out.

"Wait a minute!" Zhao Huan said, "Help me take a walk on the deck."

"Going out is just to take a breather, so I will help His Highness go out." Fei Bao agreed.

"It's full of sour smell, dirty others for no reason." In the disdainful ridicule, Liang Hongyu went back and said: "Instead of dirtying others, I have to suffer."

As she spoke, she picked up Zhao Huan and walked out.

This princess hug... no, the prince hug, it's just... too ecstasy.

Zhao Huan reprimanded: "Don't mess around, just help me out."

"Excessive indulgence, you will die, your legs are weak and your waist is weak, maybe you can stand on your own?" Liang Hongyu continued to taunt.

She is a heroine in the female middle school, and Zhao Huan weighs one hundred and forty-five, so she is relaxed and stress-free.

It's just... hey!Don't mention it.

Under Zhao Huan's repeated requests, Liang Hongyu finally let go of the prince and helped him out.

Fei Bao didn't want to leave or stay, so he just stared blankly at his feet, as if there were flowers on those stinky feet.

Zhao Huan asked: "There are more than ten boats, six to seven hundred people, are there any people who are seasick?"

Fei Bao said, "Yes, but there are more than thirty people."

"fine……"

"What's the matter?" Before Zhao Huan finished speaking, Liang Hongyu interrupted: "For a half-dead like you, there is only one."

"There are not many seasick people, so it means that crossing the sea is feasible, which is much more important than whether I am good or bad." Zhao Huan said.

"Your Highness, the voyage to the sea is only one day now, and the novelty has not passed, so it will not be revealed. It will be confirmed after another three or two days." Fei Bao said.

Fei Bao's words shattered the luck in Zhao Huan's heart.

The accompanying personal guards are mostly landlubbers from the north, and they are basically going to sea for the first time.

If the probability of seasickness is one-twentieth, it can fully support cross-sea operations.

Now that I think about it, I'm still too optimistic.

"If you want to cross the sea on a large scale, you have to prepare in advance or train full-time. It's not easy." Zhao Huan sighed.

In the era of cold weapons, physical strength is the key. If you get seasick and dizzy, you will be killed immediately when you go ashore.

This period of time must not be too short, and the effect of surprise is completely lost.

As for training specialized troops, it is feasible, but cost is the key.

According to the feedback from Salmon Island, the infantry of the Marine Corps costs the equivalent of three ordinary infantry.

When they landed, they were still alone, and no one was much better than the other.

This leads to a problem, that is, less training is useless, and more training is not cost-effective. It is really a dilemma.

While thinking, Zhao Huan had already arrived on the deck.

As soon as the sea breeze blows, I suddenly feel relieved, and the feeling of seasickness is much lighter.

Zhao Huan asked: "If you go with me today, can I get something?"

Before boarding the ship, he had arranged for Fei Bao to accompany the ship owner to learn sea navigation skills, so he asked a question.

Fei Bao said: "I have gained a little, but there are many places that need to be verified."

"Are there any difficulties?" Zhao Huan asked.

Fei Baodao: "Navigation at sea, the first thing is positioning, the position is determined, the rest is not difficult.

It's just that no one seems to know about the star-stretching technique His Highness mentioned, and it still needs to be studied. "

Zhao Huan nodded slightly, and said: "When I return to Beijing, I will immediately organize stargazers to study."

At this time, when navigating at sea, the direction of identification mainly depends on the sun, moon and stars, and a compass is also used.

These can ensure that the direction at sea is not lost, but they cannot determine the position of the ship, which is still too simple.

The reason why Zhao Huan dared to take the sea route was because this trip basically followed the coastline, and there were reference points on land, which minimized the risk.

But conquering the ocean in the future will definitely not be so simple.

Therefore, Zhao Huan proposed the star-stretching technique.

The so-called astrology is the method of using the position of the stars in the sky and their angular height to the sea level to determine the position and direction of the ship during the voyage.

This technology is one of the most important technologies that broke out in the age of great navigation, and it can be said that it is second only to the appearance of the compass.

Moreover, Zhao Huan estimated that it would not be too difficult to study.

There may be a shortage of talents in other fields in China, but there is no shortage of astronomers.

From Qin, Han to the Southern Dynasties, Taichang belonged to Taishiling, who was in charge of Tianshi ephemeris, and Sui Secretary Province belonged to Taishi Cao, and Emperor Yangdi changed Cao into a supervisor.

In the early Tang Dynasty, Taishijian was changed to Taishi Bureau, and its name was changed several times to Secretary Pavilion, Huntian Supervisory Yuan, and Armillary Sphere Supervisor, or it belonged to Secretary Province. In the first year of Qianyuan, it was renamed Sitiantai.

It was called Sitianjian in the Five Dynasties, and it was still used in this dynasty. After Yuanfeng was restructured, it was changed to Taishi Bureau.

The name has been changed, but the function has always been to observe the sky, calculate the solar terms, and formulate the calendar.

After so many years of accumulation, the data in this area is vast, and only one person is needed to combine the stars and navigation.

For the time being, only one person with a concept is needed.

There is no doubt that this person is none other than the prince.

With the star-stretching technique, you can travel around the world once, and the great geographical discovery is naturally what it should be.

Of course, it's too early to tell.

On top of that, the number of people getting seasick is increasing day by day.

When he arrived at the Huaihe River, Zhao Huan felt a little better, but out of nearly 700 people with him, more than 500 people suffered from seasickness in varying degrees.

From Xiuzhou to Huaihe, only four days!

"Navigation is difficult, not weaker than the road of Shu!" Zhao Huan, full of emotions, was worried that people would be killed, so he had to order the fleet to berth at Yunti Pass for a rest.
