After the whole sect traveled to ancient times, I led the rebellion

However, regardless of whether there are any ships docked in Qingrong City, Mu Qing also plans to take a walk there.

The population of Qingrong City is too large, almost equivalent to that of a small country. Mu Qing is now in urgent need of opening up external markets.

With the incorporation of Beiyang and Nanwan into Muqing's territory, there will be labor force, and productivity will gradually increase with the development of science and technology.

Now that steam engines have been invented, steam generators won’t be far behind.

Once we fully enter the industrial age and productivity levels improve, a large number of commodities will be produced. Only economic circulation can achieve sustainable development.

If you want to go to Qingrong City, you have to take a boat.

In fact, the shipbuilding technology of the Tianchi Dynasty is quite mature.

At this time, in terms of the strength, watertightness and structure of the ship, Tianchi Dynasty has used the iron nail connection method to ensure the strength of the hull.

The mainstream shipbuilding method uses a combination of mortise and tenon joints and nails.

In order to ensure the watertightness of the ship, caulking technology has also emerged.

People would use tung oil, lime, and hemp fiber to make twisted materials and fill the gaps in the joints to improve the watertightness of the ship.

But Anping's shipbuilding technology was obviously not yet mature.

Mu Qing was thinking about the model of Zheng He's treasure ship that he had assembled before.

She is familiar with the structure and proportions of ships.

Mu Qing quickly found Cheng Su.

Cheng Su was shocked when she learned about Mu Qing's reason:

"Build a ship? Do you want to build a sailboat?"

Cheng Su is knowledgeable, but Mu Qing asked to build a ship that can travel long distances, which is a bit difficult for Cheng Su.

She thought about the destination the ship would reach and asked:

"I remember that no one has been to Qingrong City for a long time. I wonder if there is a port there."

Mu Qing didn't know much about the port. There were only a handful of people in Anping who had been to Qingrong City, and now there was one person in Anping.

Li Min had been to Qingrong City with the army when he was young. He turned around and came over:

"The situation in Qingrong City is complicated and life is primitive. There was no port when I went there."

Li Min said with a smile, he looked at Mu Qing.

In the past two years, Li Min has been completely tied to Anping by Mu Qing. He studies medicine and teaches on weekdays, and goes to the food street for a stroll after get off work. He lives a very enjoyable life.

When he heard that Mu Qing was going to build a large ship to Anping, he immediately came over to join in the fun:

"There are few people in Anping who can build ships, and the craftsmen who can build large ships are all in the hands of the rich and powerful. If we can really build a ship, I think it will be very fast to go back and forth to Shengjing."

Li Min was telling the truth, there were indeed few craftsmen in Anping.

Mu Qing spent a long time digging out dozens of people from these cities.

It would be difficult for Anping's craftsmen to build a small boat and then build a large ship that can sail long distances.

Fortunately, the Mohist School came. The Mohist School was well-versed in mechanical engineering and had talented shipbuilders, filling the vacancy in this area for Anping.

But without the support of data, everything is just empty talk.

If they really had to follow the shipbuilding progress of this era, Mu Qing would probably have to study with Cheng Su and others for several years before they could come up with the final data.

But fortunately Mu Qing still remembered some data.

Zheng He's treasure ship is about 138 meters long and 56 meters wide, with a length-to-width ratio of about 2.46, which is just enough to stabilize the hull.

Mu Qing blurted out the proportion, and Cheng Su, who was standing beside him, seemed to be thinking about it.

Li Min looked at Mu Qing with appreciation.

The girl is very smart and deserves to be called a child prodigy in Shengjing.

Li Min no longer cares about Mu Qing's gender. Having followed Mu Qing for so long, he knows too well that Mu Qing is smart.

Mu Qing felt a little helpless. Li Min's fatherly look almost made her feel like she had recognized half a father.

Li Min loves to have a meal at Mu Qing's place every day, simply because the chef's cooking skills at Mu Qing's place incorporate various modern recipes.

Li Min is here waiting for dinner.

He watched the two of them chatting patiently.

Cheng Su still had doubts about the data presented by Mu Qing.

Just like that, the two workaholics got together and simply put together a model of Zheng He's treasure ship.

When it was time for lunch, Li Min saw that the two were still working, so he simply pulled them away.

It was said before that Li Min had irregular meals due to his study of medical books, but in fact Mu Qing was also one of the people under supervision.

Li Min waited until Mu Qing finished his meal obediently before returning to the clinic.

It took the two men and other craftsmen two days to make the model.

And when the model actually appeared, Cheng Su couldn't help but look at Mu Qing.

The proportion is the same, so this data is completely feasible.

This model was completed under the leadership of Mu Qing. Cheng Su watched Mu Qing piece together various models bit by bit. When the model appeared in front of her, the light in her eyes became much brighter.

Cheng Su looked just like Li Min did when he looked at Mu Qing castrating the piglets. In the end, she couldn't help but asked:

"What do you think of mechanical engineering? I see that you have a high talent in this area."

After that, Mu Qing could recite the entire text.

Mu Qingwan declined Cheng Su's kindness, saying that she was too busy to learn.

After Li Min, Cheng Su was the second person who wanted to take Mu Qing as his disciple.

When Mu Qing rejected her, Cheng Su secretly sighed that it was a pity.

By the way, the model was made by Mu Qing in his spare time when he was studying.

This time, relying on his photographic memory, he successfully reproduced it.

With the data and model in hand, the next step is to build the ship.

Just do it.

Mu Qing immediately started the shipbuilding project with a group of craftsmen.

Canoes, rafts and sailboats are mainly made of wood.

In fact, compared with wooden ships, steel ships and concrete ships are obviously more durable.

Cement ships are ships made of cement and steel wire (rebar) as the main materials.

Including wire mesh cement ship and reinforced concrete ship.

Cement ships are corrosion-resistant and durable.

There are many ferrocement ships in China that have been in use for more than 20 years.

Cement ships are inexpensive to build, the materials are easily available, the construction equipment and construction process are simple, the maintenance costs are low, and they can save wood and steel.

Mu Qing initially thought about building a cement ship, but the disadvantage of a cement ship is that it is heavy and has poor impact resistance, and can only be used within a certain range.

After the sailing ships are built, we can consider building some cement ships.

After all, ferrule cement ships can be used as farm ships, fishing boats and transport ships. There is no problem using them in general rivers. Steam engines can also be installed to provide additional benefits.

The speed can also be improved.
