"This thing, very common, if you say it, you may be a little incredible!"

"What the hell is that?"

Heard Ying Changsheng say this.

I couldn't help but be a little confused, and at the same time, I was also very curious.

He really didn't understand.

In life, there are things that can be seen casually.

can replace wood.

What exactly.

In the view of the public loss.

This thing probably doesn't exist.

And Win Changsheng, seeing that Gong was so eager to lose, he also directly said his own way, only to hear him explain with a smile.

"This thing, nothing else, he's iron!"

"Iron?"

For a while, after hearing this material mentioned by Ying Changsheng.

Gong Chuan Shangzao's eyes couldn't help but widen.

Immediately, the expression on his face also became complicated, and he looked at Ying Changsheng with the eyes of a fool.

Okay, iron this thing.

Of course I know it.

It's a metal.

It has a good texture and is strong and durable, which can be said to be a great material.

But can this thing be used to build ships?

In the public loser on the eye.

This is simply not possible.

The reason is simple.

Iron is a metal that is too heavy.

Isn't it true that the ship made out of this thing will sink to the bottom of the water as soon as it enters the sea?

Thinking of this, Gong Lose couldn't help it, looked at Ying Changsheng in front of him with a smile and a smile, and then said helplessly.

"Nineteen Princes, aren't you making nonsense, how can this iron build ships? If the ship he built really entered the water, wouldn't it sink directly to the bottom? ”

"Hahahaha, no, no!"

For a while, with the sound of Gong Losing and Shangzao, Win Changsheng laughed a few times.

He said to Gong Zhi.

"Although the iron is heavy, it does not sink to the bottom after entering the water!"

"How is that possible?"

Hearing this, Gong lost Shangzao but did not believe it, because he clearly knew that any kind of metal, after entering the water, would sink to the bottom, and he only saw him say to Ying Changsheng.

"If the nineteenth prince doesn't believe it, the minister can show you right now!"

As he spoke, Gong Chuan Shangzao took off the saber on his waist, and then he planned to put his saber into the water to see if this saber would sink to the bottom!

Seeing this situation, Ying Changsheng hurriedly stopped the public from losing and said.

"Who told you to put iron directly into the water?"

"I'm telling you, the reason why iron doesn't sink to the bottom is not that he won't sink into the water for such a thing!"

"If you throw an iron ball or other shape of iron into the water, it will naturally sink into the water, but if the iron is processed into a special shape, processed into the shape of a ship, then it will not sink to the bottom 100 percent!"

"Oh?"

For a while, Ying Changsheng's voice fell.

I couldn't help but be a little surprised.

And Win Changsheng had no choice but to explain to him the truth in this.

I only heard it, and Ying Changsheng said with a smile.

"Well, there is a special truth involved, he is called buoyancy!"

"The reason why objects can float on the surface of the water is purely because of the effect of buoyancy, so that the objects can float steadily on the surface of the water!"

"Wood can float directly on the surface of the water due to its natural quality and density, but other objects can also be processed to make it buoyant, so that it can float on the surface of the water!"

Saying that, Win Changsheng made a bet on the loss of the Gong.

"If you don't believe me, you can try!"

"Go find an iron bucket and throw it in the water to see if the bucket sinks!"

Iron buckets are a relatively common thing in the current Daqin.

Because of traditional wooden barrels, it is really not easy to make.

It takes a good carpenter to successfully make it after a while.

In such a situation.

Directly use iron, cast iron barrels, and now in Daqin, it is also extremely popular.

After hearing Win Changsheng's order, Gong Lose Shangzao did not dare to slack off, he hurriedly sent people, and after a while, he slipped an iron bucket for Win Changsheng, and when the iron bucket was lifted over.

I saw that under the command of Ying Changsheng, the soldiers on the side threw the iron bucket into the water without hesitation.

For a time, after the iron bucket entered the water.

A surprising scene appeared.

This iron bucket made of iron did not sink directly into the water as everyone imagined.

On the contrary, this iron bucket floated directly above the water.

See this scene.

Originally, he was still suspicious of everything that Ying Changsheng said, but at this time, he was completely convinced, and he said to Ying Changsheng.

"Nineteen princes, the minister understands, but, in the future, I, Daqin, want to use iron to directly cast ships?"

"Well, what a huge mold would have to be made, and how many steel furnaces would have to be used to cast a ship?"

For a while, Gong Yi Shangzao frowned a little, and said to Ying Changsheng.

Yes, it is possible to build ships with iron, although it is possible.

However, if you were to cast a boat out of iron, it would seem impossible.

Because the ships are just too big.

If it is used for casting, it is not easy to make the mold alone.

And after hearing the voice of Gong Lose, Win Changsheng couldn't help but laugh a few times and said to him.

"Hahahaha, who told you that it was used for casting?"

"If you don't cast, do you want a blacksmith to forge a boat?"

For a while, the public lost and frowned even more.

It seems to be harder than casting.

Seeing that he didn't understand the joints, Ying Changsheng had no choice but to explain to him patiently.

"The ship is too big to be cast directly!"

"It should be, after casting the keel and other parts, and then putting the iron planks together, and then connecting them in the dock, so that a ship can be successfully made!"

For a while, when the method that Ying Changsheng said was said, he said it.

Gong lost and made it clear in an instant.

Indeed, this is a good idea.

In this way, you can easily make an iron boat!

But soon.

But the public lost and the creation fell into a new difficulty.

I saw him standing on the edge of the Wei River, looking at the boats on the river, and said to Ying Changsheng.

"This method of the Nineteenth Prince is not bad, but the problem is that the weight of the iron ship must be much larger than that of the wooden boat, such a large iron boat, if he sails in the water, the wind will probably not be able to blow?"

"Even if it can be blown and moved, the speed will probably be reduced a lot, right?"

"In this way, if it is made, it will not be able to sail in the rivers and oceans......"
