Chapter 420 A New Difficulty
"This thing is very common. If you say it, you may be a little unbelievable!"

"What the hell is that?"

I heard what Ying Changsheng said.

Gongshu Shangzao couldn't help being a little confused, but at the same time, extremely curious.

He really didn't understand.

Everywhere in life.

able to replace wood.

What exactly is it.

From the perspective of Gongshu Shangzao.

This thing probably doesn't exist.

And Ying Changsheng, seeing that Gongshu Shangzao was so eager, also directly stated his own method, only to hear him explaining with a smile.

"This thing is nothing but iron!"

"iron?"

For a while, after hearing the material Ying Changsheng mentioned.

Gongshu Shangzao couldn't help but widen his eyes.

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

Well, iron this stuff.

Of course Gongshu Shangzao knew.

It's a metal.

The texture is excellent, and it is strong and durable, which can be said to be the best material.

But, can this thing be used to build ships?
Create an eye on public transport.

This is simply not possible.

the reason is simple.

Metal like iron is really too heavy.

Wouldn't the boat made with this thing sink into the bottom of the water as soon as it entered the sea?

Thinking of this, Gongshu Shangzao couldn't help but looked at Ying Changsheng in front of him dumbfounded, and then said helplessly.

"Young Master Nineteen, aren't you out of ideas? How can this iron build a ship? If the ship he built really enters the water, wouldn't it just sink to the bottom?"

"Hahahaha, it won't happen, it won't happen!"

For a moment, Ying Changsheng laughed a few times following Gongshu Shangzao's voice.

He said to Gongshu Shangzao.

"Although iron is heavy, it won't sink to the bottom after entering the water!"

"how is this possible?"

Hearing this, Gongshu Shangzao didn't believe it, because he knew very well that any kind of metal would sink to the bottom after being put into the water, so he said it to Ying Changsheng.

"If the nineteenth son doesn't believe it, I can demonstrate it to you immediately!"

With that said, Gongshu Shangzao took off the sword from his waist, and immediately planned to put his sword into the water to see if the sword would sink to the bottom!
Seeing this situation, Ying Changsheng hurriedly stopped Gongshu Shangzao and said.

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

"Let me tell you, the reason why iron doesn't sink to the bottom doesn't mean that something like iron won't sink in water!"

"If you throw an iron ball or any other shape of iron into the water, it will naturally sink into the water. However, if you process the iron into a special shape, it will The shape of the ship, then, he is [-]% unsinkable!"

"Oh?"

For a moment, Ying Changsheng's voice fell.

Gongshu Shangzao couldn't help being a little surprised.

As for Ying Changsheng, he had no choice but to explain the truth to him.

I only heard Ying Changsheng say with a smile.

"In it, there is a special principle involved, which is called buoyancy!"

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

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

Saying that, Ying Changsheng made a bet against Gongshu Shangzao.

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

"Go find an iron bucket, throw the bucket into the water, and see if the bucket will sink!"

Iron barrels are relatively common in the current Daqin.

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

It needs a good carpenter, and it can be successfully made after a long period of operation.

In this situation.

Directly using iron to cast iron barrels is also extremely popular in Daqin.

After hearing Ying Changsheng's order, Gongshu Shangzao didn't dare to neglect, he quickly dispatched his manpower, and within a short while, he brought an iron bucket to Ying Changsheng, and when the iron bucket was brought 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 while, after entering the water with the iron bucket.

A surprising scene appeared.

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

On the contrary, the iron bucket floated directly on the water.

see this scene.

Gongshu Shangzao, who was still skeptical about everything Ying Changsheng said, is now completely convinced, he said to Ying Changsheng.

"Young Master Nineteen, I understand, but, is it possible that in the future, Daqin, I will use iron to directly cast ships?"

"Well, in this way, what a huge mold must be made, and how many steel furnaces must be used to cast a ship?"

For a moment, Gongshu Shangzao frowned, and said to Ying Changsheng.

Yes, it is feasible to use iron to build ships.

However, it seems impossible to cast a boat out of iron.

Because the ship is too big.

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

And after hearing Gongshu Shangzao's voice, Ying Changsheng couldn't help laughing a few times and said to him.

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

"If you don't cast it, could it be that you let a blacksmith forge a boat?"

For a moment, Gongshu Shangzao frowned even more.

This seems to be more difficult than casting.

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

"The ship is too huge, of course it cannot be directly cast!"

"It should be, after casting the keel and other parts, then put the iron ship plates together, and then connect them in the dock, so that a ship can be successfully produced !"

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

Gongshu Shangzao understood instantly.

Indeed, this is a good way.

In this way, an iron boat can be easily made!

But soon.

But Gongshu Shangzao 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.

"The nineteenth son's method sounds good, but the problem is that the weight of an iron boat must be much greater than that of a wooden boat. If such a big iron boat sails in water, the wind will Maybe it’s a little too much to blow?”

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

"As a result, even if it is built, it will not be able to sail across the rivers and oceans..."
