When Du Shizhou saw the two coming back, he immediately shouted:

"My lords, two adults, I have a way to help this merman!"

Hearing him shout like this, the official immediately darkened his face and said to Yeming and Miaotong:

"Two adults, this person is an incompetent maniac, he is talking about some crazy words that he doesn't know what to call crazy, and the little one will drive him away!"

As he spoke, he called another servant and planned to take the man away.

Du Shizhou was reluctant to leave, shouting that there was a way.

Seeing this, Miao Tong thought this person was interesting, so he said:

"Wait a minute, let him go, let him talk about what can be done."

"Do you hear me, let me go, hurry up!"

Du Shizhou broke away from the two officials, and hurriedly said to the two young men and girls in front of him.

"Two adults, my solution is to install an iron tail fin for him!"

As soon as these words came out, the onlookers burst into laughter.

"Hahaha, it's started again, Du Dashao started talking crazy again."

The crowd laughed and laughed, completely dismissing his words as madness.

Du Shizhou's face was a little embarrassed and said:

"What are you laughing at? What's funny, I say yes, I'm sure! ”

Seeing him say this, everyone laughed more and more happily.

Miaotong is a jumper, and after listening to Du Shizhou's statement, I feel very interesting.

"What you say is true? Can a tail fin made of iron work? ”

"Useful, absolutely useful!"

Du Shizhou said with great certainty,

"Trust me, I can do it."

Seeing that Miaotong seemed to believe it, someone next to him hurriedly told Du Shizhou that his words were not credible, and even told him about his family's situation.

The Du family was originally the second-in-command of the ship merchant among the four families and three merchants, and it was considered a famous family in the entire Pingbo Mansion.

Originally, such a big family, without accidents, is not easy to collapse.

But Du Shizhou's father was a bold one.

As a shipper for generations, his father had a whimsical idea to build a ship out of iron.

All the ships in existence are wooden ships, at most they are covered with a layer of iron sheets, and they have never been completely iron.

At first, his father just tried to make an iron model, put it on the water, and found that it could actually float.

This gave him great encouragement, thinking that if he could build a large iron ship, the Du family would definitely go down in history.

So he tried to build an iron boat the size of a small fishing boat.

This time, it worked.

When his father saw this, he was overjoyed and thought it would be okay to do so.

Immediately, he spent a lot of money to build an iron ship the size of a merchant ship.

As a result, this time, for some reason, the iron ship sank into the sea and failed to make the trip.

But his father did not give up, and did not hesitate to spend another iron ship to come out, this time failing again.

It's just that after seeing how a small iron boat can float on the water, how it is willing to give up and start to keep trying.

Du Shizhou also studied the manufacture of iron ships with his father since he was a child.

But for some reason, as long as the iron ship is large enough, it will not be able to make it and will sink.

Father and son didn't give up and kept trying.

As a result, the large iron boat that could travel on the water had not been completely made, and the Du family could not support the cost and collapsed first.

His father's long-cherished wish for an iron ship was not fulfilled, and he became depressed and bedridden, and died soon after.

His wife was originally the daughter of the family, but when she saw that the Du family was collapsed by the father and son, she also abandoned Du Shizhou and left in disappointment.

In this way, a good Du family, just gone.

Although the Du family collapsed, Du Shizhou still did not give up.

Not only because his father told him before he died that he must make a large iron ship, but also because he himself was unwilling and wanted to prove that his father and son were right.

The people around him said this very sarcastically, thinking that Du Shizhou was completely an ignorant fanatic who had lost his mind.

But after Miaotong heard this, she was very interested and asked:

"Did you really make an iron ship that can float on the water?"

"Of course, I still have a few small models in my house!"

Du Shizhou saw that this mage seemed to be very interested, and he was immediately a little excited.

In fact, not only Miaotong, Yeming is also very interested in this so-called iron ship.

Seeing Du Shizhou's sworn appearance, he said:

"Let's go and measure the tail of the giant shark first."

When Du Shizhou heard this, he happily climbed over the fence, took out a cloth ruler, wooden board, and charcoal, and stepped forward to measure the size of the giant shark's tail.

The giant shark is very cooperative, even if he accidentally presses the wound while measuring, he will not move.

Du Shizhou wrote down the size of the broken tail on the wooden board with charcoal, and after writing it down, he nodded with satisfaction.

Then he came out of the fence and said to Yeming:

"My lord, I've already measured the size, and now I only need enough iron to make an iron tail fin."

Ye Ming smiled and asked, "Don't you have enough iron?" ”

Du Shizhou was a little embarrassed and said:

"All the iron in the house is used to build ships, and there is no extra ......"

Ye Ming smiled: "Then provide you with enough iron and see how you do." ”

"Yes, thank you, thank you, thank you!"

When Du Shizhou heard this, he was very happy and nodded again and again.

Yeming immediately instructed the officials to notify the smelter to prepare, and let Du Shizhou try it at that time.

When everyone around heard this, they all spoke to stop it.

"My lord, this Du family has already collapsed their own family, if they are allowed to mess up again, I am afraid that the smelter will also be destroyed!"

Ye Ming smiled and said:

"Just let him try this time, even if there is a loss, it won't be too big."

When everyone saw this, they knew that they couldn't stop it, so they could only admit it.

In fact, it is not necessary to say how much they care about those things.

The main thing is to be able to cause a little trouble to others casually, and it is still very fulfilling.

Du Shizhou was very happy to see that Yeming and the two were willing to support him, and invited the two to his house on the spot.

Ye Ming happily agreed, and Miao Tong was also a little eager to meet those little iron boats.

Du Shizhou's residence is not far from here, and it will take a short time to arrive with the two of them.

The Du family's mansion and the like have long been sold, and now all that remains is a shipyard and a small house next to it.

Now Du Shizhou lives in a small house next to the dock.

As soon as he opened the door, he could see that there were various models of ships, mostly wooden and iron.

Miao Tong took a fancy to one of the half-man-tall iron boats at a glance.

Don't look at it as just a model, the various internal structures, but they are completely reduced according to the large ship, the big ship should have, and this model ship is also not lacking.

"This ship looks like it, if it can be made, how big it will be!"

Miao Tong couldn't stop admiring.

Seeing that his work was recognized, Du Shizhou puffed up his chest proudly and said:

"This ship is the absolute success I have developed, and as long as there are enough materials to make it, it will never sink.

The ship is divided into three levels, upper, middle and lower, and can carry 500 people! ”

"Is it so powerful?"

Miao Tong's eyes lit up, she was very curious about this kind of new thing.

"Of course, my father and I have failed so many times, and finally succeeded, and now we are short of the last materials and manpower support.

If it can be done, it will definitely go down in history! ”

Du Shizhou said, his eyes showing infinite yearning for the future.

Yeming unceremoniously poured cold water on him:

"You'd better get the iron tail fin out of the matter first and prove your skills.

Otherwise, I'm afraid you won't have a chance to realize this idea in this life. ”

Hearing what Yeming said, Du Shizhou was immediately beaten back to reality.

But instead of frustration, he was full of fighting spirit:

"It's just a tail fin, a little thing!"

As he spoke, he cleaned up the table top full of various iron parts, made room for it, took paper, pencils, rulers, etc., and wrote and drew according to the size of the broken tail written on the wooden board.

Yeming and Miaotong were both a little curious, looking at him left and right.

I found that this cartographer was quite good, and after a while, he drew a tail fin pattern, marked with various sizes, materials, etc.

Miao Tong took a closer look and found that his so-called iron tail fin was not completely made of iron, but also used some oak gum and cowhide.

Immediately asked puzzled:

"Didn't you say iron tail fins? Why do you need all these things? ”

"Iron is the main body, but you can't use iron completely, otherwise it will easily wear out, and it won't take long to replace it, which is too troublesome.

With some glue and cowhide, you can make it last longer. ”

Miao Tong looked at the tail fin on the picture, and couldn't help nodding and said:

"If you can really make it, maybe you can really make the mermaids swim normally in the sea."

Du Shizhou patted his chest and said:

"Yes, for sure!"

As he spoke, he heard his stomach rumble.

Miao Tong heard the sound and asked:

"How. Haven't you eaten yet? ”

"I'm going to study the iron ship, and all the money is used to buy materials, and now I have one meal a day."

"A meal?"

Miao Tong glanced at Du Shizhou's emaciated figure, thought about it, and handed him the whole roast chicken wrapped in his hand:

"This is for you, remember, it's not for you, you have to do what you say and make an iron tail fin."

Du Shizhou was not polite, and hurriedly took it, confidently assuring:

"Don't worry, no problem."

As he spoke, he couldn't wait to nibble on the roast chicken.

Miao Tong saw that he ate so deliciously, he drooled a little, and suddenly regretted giving it to him, and felt that it was better to keep it for himself!

Ye Ming smiled and patted Miao Tong on the shoulder, pointing to the snack street along the coast in the distance.

Seeing this, Miao Tong smiled, pulled the corner of Yeming's clothes with his backhand, and walked quickly to the snack street......

When they came back, Miao Tong was very satisfied with a large bag of food in her hand.

Du Shizhou had already finished eating the roast chicken, and after eating enough, he felt that his whole body was full of strength.

Without being urged by others, Du Shizhou said a little impatiently:

"The design drawings are ready, let's go, let's go to the smelter."

The smelters in Binh Bo Province were used to manufacture iron parts and weapons for ships.

In the face of the design drawings taken out by Du Shizhou, there was nothing to be done.

Without him, there is no suitable mold.

In this regard, Du Shizhou said that he can make molds, but he needs a few helpers and a smelting room.

Fortunately, Yeming was appointed by Yuan Zhixin, and he had a lot of authority, so he directly allocated a smelting room and seven helpers to Du Shizhou.

The smelters in the smelter are different from others, and they have a lot of respect for Du Shizhou.

In their words, only those who do this line of work know how powerful the Du family's ability to build iron ships is.

Many old smelters have great respect for the skills of the Du family.

Seeing the design of the iron tail fin taken out by Du Shizhou, several smelters were amazed by the ingenuity of its conception.

Some old smelters said that if it weren't for the improvement of smelting skills in recent years, they really wouldn't be able to make this thing.

Speaking of which, the defeat of the Liangren outside the Lumen Pass in the north was a weapon made by relying on new smelting technology.

The core point of the new technology is that today's smelters use coal.

The so-called coal is carbon that is naturally produced in some special mountains.

After the charcoal is burned, its temperature is far from being comparable to that of traditional charcoal.

In addition, the bellows technology has also been greatly improved compared with the past, and the wind power is stronger.

In this way, the smelted iron is purer and tougher.

If the standard sword that is smelted now is brought to hundreds of years ago, it will definitely become a divine weapon that the people of the rivers and lakes want to get when they break their heads.

But these things are just rotten street goods used by soldiers now.

Once the smelters focus on something, others are ignored.

Miao Tong was very interested at first, and felt that such behavior was very mysterious.

But after watching it for a while, I got bored and yawned.

It didn't take long for him to say to Yeming:

"Big liar, how long will this be!"

Ye Ming said with a smile: "The mold has not been made yet, it must be completely completed, let alone half a month." ”

"Ah, for so long? Then are we still in time to save the mermaids? ”

"Anyway, the merman clan is like this, and it doesn't make much difference if you play a few days earlier."

"Uh~~~ makes sense."

"It's useless for us to stay here, let's go, go to the giant shark people, you will strive to awaken some more bloodlines in the past two days and learn to communicate with the shark people."

"No problem, it will be completed in less than three days!"
