Don’t wait, the young man’s head is gone, and he is sad.

There are many people in this world who are sad, desolate, and give up on themselves for a long time. After wasting time, they still accomplish nothing. Apart from lamenting the unfairness of fate, they are all left with chaotic grief.

Zhu Cijing did not indulge in sadness. After all, it was just a memory of his previous life. In this life, the Ming Dynasty did not perish, and the Ming Dynasty was rising strongly, and it was just in need of hard work to seize maritime hegemony in one fell swoop.

He will not sigh all day long, not be enterprising, and slowly wait for the powers to surpass him, and then he will be sad.

Now, with the armored warships, the Ming Navy will inevitably be invincible. Of course, the premise is to make it first.

The next day, after the morning court, he summoned Bi Maokang, Sun Yuanhua, Wang Zheng, Song Yingxing, Xu Fuyuan and Xia Yunyi, to hold an imperial meeting to discuss the production of iron armored warships.

As soon as these people gathered in the small conference room of the Ganqing Palace, they knew that the emperor had something new to them to do.

Sure enough, as soon as Zhu Cijing came in, after the lord and ministers greeted him, he said directly: "Everyone, I'm asking you to come today to discuss the issue of armored warships, which is to cover the outer surface of the warship with a layer of iron plate. In this way, not only cannonballs be difficult to damage the warship, but the warship itself can also be used as a weapon to impact the enemy's warships. Facing wooden warships, armored warships will definitely be invincible!"

When everyone heard this, some were stunned, some were surprised, some were thoughtful, some had different expressions and different reactions.

It is not something that no one has ever thought about covering iron plates outside the battleship, but this is not a very simple thing, because the iron plate is quite heavy. If the entire battleship is covered with a layer of iron plate, the weight will be terrifying. According to the size of the current super battleship, a pack of iron plates will definitely be heavy when it is launched!

Of course, it is not that they can't make warships that cover iron plates, but to be as big as the super battleships now, they can basically not do it. The weight can't even hold on to the existing steel brackets in the dock, so who dares to try it?

Zhu Cijiu took everyone's expressions in his eyes. He knew that someone would definitely ask questions because this was not a fantasy idea, and someone must have thought of it.

However, there have been no armored warships in the Ming Dynasty, which proves that they must have problems that they cannot solve.

Sure enough, after a while in the conference room, Sun Yuanhua bowed and said, "Your Majesty, the minister you mentioned also thought about it. However, to resist the attack of shells, the thickness of the iron plate must be at least more than half an inch. In that case, a piece of iron plate as big as a door panel weighs several hundred kilograms. It is not a problem to be a small iron armored warship, but it is difficult to achieve the size of the super battleship now."

Zhu Cijiu shook his head rarely and reminded him: "No, no, Chuyang, more than half an inch is a light iron plate. If a thick wooden board is placed on the back, no half an inch is required, two minutes thick is enough. If the material is improved and the toughness of the iron plate is increased, one minute thick is enough."

Sun Yuanhua has never tested this. Who would bored adding a layer of thick wooden board behind the iron plate? When he tested it, he used all the light iron boards.

Fortunately, everyone is familiar with the emperor's temperament. If the emperor speaks kindly, it means he is not angry, he is just discussing with you. Otherwise, the few words will be enough to scare people to sweat. Now, Sun Yuanhua just touched his head awkwardly, indicating that he knew he was wrong.

Under Zhu Cijiu's deliberate guidance, the academic atmosphere of the Ming Dynasty has been relatively relaxed. No one is as timid as before. Sun Yuanhua was denied, and Bi Maokang bowed again: "Prince, please forgive me for being brave. Even if it is a bit thick, it will be more than twice as heavy as a wooden warship. According to the size of the current super battleship, it may not be sunken. However, those gun doors are probably flooded."

Upon hearing this, Zhu Cijiu nodded, then picked up the brush that had already been placed on the table, dipped it ink, and brushed it on the large white paper in front of you.

His current painting skills are not good. With his deliberate practice, although he may not be able to reach the level of the famous painter Emperor Zhao Ji, he is probably not much worse.

Under his writing, the side outline of a super battleship was slowly and quickly formed, which was so vivid that everyone could not help but look admirable in their eyes.

Of course, he was not here to show off his painting skills. After drawing a contour, he stopped writing and did not draw in detail.

He put down his brush and pointed to the super battleship on the picture and said: "The current ship shapes are almost the same, with the arc bottom, like a long scoop of water."

Everyone didn't understand what the emperor meant. It was not only the Ming Dynasty, but it has been like this for thousands of years.

However, the emperor had to react a little, and everyone nodded in cooperation.

Zhu Cijing picked up the brush and drew a waterline again. The boat was like floating on the water.

Immediately afterwards, he pointed to the following part of the water and said: "The reason why the boat can float on the water is because it discharges this part of the water. In fact, the weight of the boat is equal to the weight of the water it discharges, which can be called the displacement of the boat."

At this time, there was no concept of displacement. Everyone frowned and pondered when they heard this. What does displacement mean?

Zhu Cijing then explained: "Cao Chong said that everyone knows the elephant. He is actually using the displacement to calculate the weight of the elephant. When the elephant stands up, the ship sinks, draws and marks the line, then leads the elephant away, and then slowly presses the boat to the same position with a stone. In this way, the weight of the stone is equal to the weight of the elephant. Think about it, whether it is the weight of the stone or the weight of the elephant, is it the weight of the water they discharged? "

This is more intuitive, and everyone suddenly realized it. Obviously, they had already understood the meaning of displacement.

Seeing that everyone had already understood the concept of displacement, Zhu Cijiu picked up the brush and drew it.

This time, he was painting a very strange boat, just like adding a long shuttle to the bottom of the original arc-shaped boat.

Seeing such a strange hull structure, everyone showed surprise expressions.

If we look at it from the perspective of aesthetics, this structure is ten times less ugly than the old-fashioned structure. Why did the emperor draw such an ugly ship?

Zhu Cijing still only drew a contour, but this time he stopped writing with the waterline.

He put down his brush and pointed to the newly added shuttle type below and said, "If you add such a long shuttle-type sealed cabin at the bottom of the ship, will its displacement increase? Is it the larger the sealed cabin of this shuttle type, the greater the displacement of this ship? If the displacement is larger, does it mean that the ship can make heavier? In this way, is there any problem with covering the outside of the ship with a layer of iron armor?"
