“Yes, remember.”

Zhou Yi also said to Zhao Xu in a low voice.

The two looked at each other, and everything was self-evident.

After giving Zhou Yi a few more words, Zhao Xu, Chen Shou and others returned to Pingcheng City.

Because it is getting late, I will be able to return to Yancheng tomorrow.

He simply called Chen Shou to discuss the construction details of the sail warship with him.

For Chen Shou, although the King of Yan gave him drawings.

However, I do not agree with the existence of some unique structures on the sail warship.

So he said, "Your Highness, the lower lord doesn't understand why the sails on this boat are made of soft sails, not hard sails. It seems that hard sails require fewer people to manipulate them."

Zhao Xu nodded slightly.

After a closer discussion, he was quite sure of Chen Shou's shipbuilding skills.

He can basically tell the structure of the warship one, two, and three.

He also understands the different functions of hard sails and soft sails.

What the two are controversial about is which structure is the best.

"There are few people who need to control the sails, but one of the disadvantages of hard sails is that they have a small area of ​​wind consuming, which cannot increase the speed of warships. The soft sails have a large area of ​​wind consuming, which can increase their speed at sea higher." Zhao Xu said.

In contemporary times, ships used hard sails in Dasong.

This kind of hard sail is densely packed with keels, and the sail will not deform greatly when the wind blows.

The soft sail has few keel bones, and the wind will show a large curve when blown, so the area affected by the wind will be larger.

This is like a kite. A single-sided kite is definitely not as strong as a tube-mounted kite.

Same principle.

Soft sails at sea will provide greater power to warships.

"So that's it." Chen Shou suddenly realized.

He continued to ask: "Why are the buildings on the warships moved to the hull?"

"This is a matter of center of gravity. If the center of gravity is at the bottom, the lower plate will be more stable. Only when the ship sails on the sea can it resist wind and waves." Zhao Xu explained patiently.

Dasong's ship has a characteristic, such as a tower ship.

This ship builds a house-like structure on the deck.

This leads to heavy above and light below.

This structure can accommodate more troops to fight on the shore battle, but it is easy to capsize when encountering large storms.

Therefore, this structure is not bad in inland rivers and offshore, but it is not good if the ocean encounters strong winds and waves in the sea.

The word "center of gravity?" is very new to Chen Shou.

Seeing Chen Shou’s doubts, Zhao Xu explained what the center of gravity is.

When Chen Shou heard this, his eyes gradually became different when he looked at Zhao Xu.

Just now, when King Yan asked him about the construction of the warship, he was very wise and was a little proud.

Now after two problems, he found that the King of Yan was hidden.

He didn't understand these things either.

His own master never taught him this.

"If the officials still don't understand anything in the future, they will often go to Yancheng to ask His Highness for advice." Chen Shou looked like a student at this time.

Zhao Xu smiled and said, "That's OK, but Master Chen should not belittle himself. Your shipbuilding skills are indeed good. It's just that the ships that have always been Dasong either travel in the inland rivers or near the sea, and there has never been a need to cross the sea far away. You boatmen will not consider these structures."

Chen Shou nodded, and had to say that King Yan really revealed it in one sentence.

He never thought of going deeper into the sea.

So when he saw this kind of warship drawings that could penetrate deep into the sea, he would be moved and wanted to try to challenge himself.

"Please continue to answer questions for the officials. Why doesn't this warship use a watertight cabin?" Chen Shou pondered for a while and asked again.

King Yan will go back tomorrow, and he doesn't want to miss this opportunity.

Not only must he be able to build it, but he must also understand everything about this warship.

"Although the watertight cabin can make the warships resist sinking, it will lead to the inability to thicken the hull and the multi-layer decks being laid. In this way, the warships have weak resistance to strikes and fewer artillery loads."

The drawings he gave to Chen Shou this time were actually designed with reference to Garen Ship.

This kind of ship has a multi-layered hull, which is half a meter thick, very strong and has strong anti-aircraft ability.

At the same time, it uses an oblique rib structure, which can lay multiple decks, and each deck can be equipped with a large number of artillery.

It uses soft sails, which have a large area of ​​wind consuming and can sail at extremely high speeds.

The disadvantage is that soft sailing is troublesome to operate and requires a large number of skilled sailors.

Simply put, this kind of warship is suitable for ocean-going and maritime artillery battles.

However, near the sea, the wind direction changes rapidly, so this kind of warship is not as good as Dasong's hard sailing ship.

So, in the end, the two ships have different functions.

One is suitable for warships and the other is suitable for commercial use.

Dasong never thought of conquering the ocean and exploring other continents.

Emperors of all dynasties believed that Middle Earth was the world.

Of course, craftsmen will not be allowed to explore the ocean-going seaship technology. It is really impossible for craftsmen from Dasong to do so.

Until midnight.

Chen Shou felt embarrassed when he saw Zhao Xu yawning all the time, so he left with satisfaction.

The next day, although Zhao Xu was very sleepy, he still got up early.

Chen Shou sent Zhao Xu outside the west gate of Pingcheng City and returned reluctantly.

For him, he finally had a confidant in the matter of shipbuilding.

In more than a day, Zhao Xu arrived in Yancheng.

After returning to the palace, Luan'er untied the fox fur for him and brought it to the hand stove.

He sat down and squeezed his shoulders and back, and he was very well-behaved.

At this time, Feng'er also came over, her pretty eyes were full of power.

But when he saw Zhao Xu, he immediately turned into soft charm.

Seeing this, Zhao Xu joked: "Yeah, who is the one who messed with Butler Feng again."

"Puff..." Feng'er couldn't help but smile when she heard this.

She came over and pinched Zhao Xu's right arm and said softly: "Your Highness, you don't know that yesterday, the people from the Xie family came to the door to deliver gifts. There was a vase inside. Just now, a maid accidentally messed up. I said a few words to her, but she even argued with me."

"Is the Xie family here?" Zhao Xu heard the key information from Feng'er's words.

"Hehe..." Luan'er covered her mouth and smiled. She said to Feng'er: "Look, I'll say that your highness won't care about these trivial matters."

"You know." Feng'er reached out to scratch Luan'er, and the two of them played.

Then Feng'er acted coquettishly and said, "Your Highness, what's happening in the royal palace is also a matter."

Zhao Xu came back to his senses and smiled, "I have called you, Butler Feng, and the matter in the royal palace will naturally be punished. The state has national laws and family rules. The royal palace will naturally have the rules of the royal palace. If it is punished, it must be punished."

Feng'er smiled, and this Feng Butler made her very happy.

However, at that time, the King of Yan just casually told her to manage the royal palace.

Now many servants in the royal palace think that she is the personal maid of the King of Yan, so she likes to meddle in other people's business.

So she told this.

After hearing this, Zhao Xu understood why Feng'er was wronged.

He said, "Okay, I will write a handwritten order to officially let your girl be a housekeeper and live up to the housekeeper's addiction."

Luan'er has a quiet personality and only likes to be a female girl.

But Feng'er couldn't stay idle and didn't give her something to do, which would cause trouble.

"Thank you, Your Highness." Feng'er was overjoyed, and her arms were much more joyful.

Zhao Xu shook his head helplessly and said to her: "The king gave you the first order to invite the Xie family to the royal palace."
