The importance and role of the keel to the sea ship was explained to all the craftsmen present, and the drawings of the sea ship manufacturing were handed over to all the craftsmen present. Pen & Fun & Pavilion www.biquge.info

This time, Li Mu only chose two kinds of sea vessels.

One is the famous sea ship Fu Ship of the Ming Dynasty, that is, the drawings of the interior and exterior structure of the Fu Ship that are copied by technology in modern times, based on Zheng He's treasure ship that went to the West seven times.

There is also a flying clipper invented by the United States, and the reason why Li Mu chose this kind of ship is completely because of the speed of the clipper.

The same clipper is also the fastest sailboat design in the history of sailing in the history of sailing, and the fastest speed of clippers can reach the historical record.

It is the Great Republic built by the United States in 1853, it is 93 meters long, 16.2 meters wide, 9.1 meters deep, displacement of 3400 tons, mainmast height of 61 meters, the whole sail area of 3760 square meters, the speed of 12~14 nautical miles per hour, only 13 days to cross the Atlantic.

The speed of the clipper ship is a natural escort ship, which is also the only purpose for it to enter Li Mu's eyes and bring it to Datang.

In the Tang Dynasty, the clipper ship would not have been invented by the United States for the purpose of transporting goods.

The main function of Li Mu's clipper ship is an attack frigate, and the auxiliary function is to transport goods.

In the Tang Dynasty, the clipper will become the frigate of the Fu Ship, carrying out ocean trade, and the clipper can rely on its excellent speed, and during the ocean period, if it encounters pirates, with its excellent speed, with its excellent speed, it can annihilate the enemy out of danger.

There is another reason why Li Mu chose the flying clipping boat, that is, to equip the Muhai with a frigate, and the flying clipper is the only kind of sailing ship that can keep up with the speed of the Shangmuhai.

In Li Mu's concept, in Datang, he will build an attack fleet with the Muhai as the command center and the clippers as the attack frigates.

There is also an ocean-going colonial trade fleet centered on a few or a dozen fortune ships and escorted by clippers.

These are the two functional fleets in Li Mu's heart in the early days of the Tang Dynasty.

Li Mu did the same.

Teach the drawings to the craftsmen below, so that they can slowly figure out how to build these two kinds of sea vessels more efficiently.

The next thing Li Mu has to consider is how to improve work efficiency.

The development of human civilization is inseparable from tools, and tools are indispensable promoters for the development of human society.

Because human beings learned to use tools to obtain fire, they had the possibility to turn food into mature food, and fire was also one of the key reasons for the gradual development of human beings from a barbaric society to a feudal society.

And how did humans enter the industrial society?

Some people say that it is the development of coal and the exploitation of oil, but in fact, it is the application of electricity that really brings mankind into the era of industrialization.

Not far from the salt drying field, Li Mu instructed the laborers of the Tang Dynasty to erect solar panels and form them into a small solar power plant.

There wasn't a lot of electricity, but it was enough to run some equipment, such as a few slicers that could slice logs, and a dozen small wood cutters for carpenters.

These basic equipment were all brought to Datang by Li Mu from modern times.

With these equipment, the initial treatment of wood will be twice the result with half the effort, and the efficiency will be increased several times.

After solving the problem of preliminary treatment of logs, Li Mu also had to consider another problem.

That is, the logs that are now cut cannot be directly used to make wood for sea ships, and the wood that has just been cut must be dried for several years before it can be used for the manufacture of sea ships.

Not to mention the manufacture of sea boats, even the wood used in the manufacture of furniture, the wood must be dried now before it can be carved.

However, Li Muke did not have time to wait for the wood to be placed there, dry it for a few years, and then let the craftsmen make the sea boats.

Time waits for no one, not to mention that Li Mu can't afford to wait, although his lifespan is now 480 years, he can wait, but for Li Mu, waiting is a waste of time.

Therefore, he has brought a complete set of solutions for the drying of wood from modern times, log board drying solutions.

This time, Li Mu didn't bring wood drying equipment, it was too big, and besides, Li Mu had also seen the process of drying the wood used to make furniture.

Coupled with the information about wood drying prepared by Liu Yumei, Li Mu can completely realize the method of drying wood without modern equipment in Datang.

This method is to build a large marine wood drying kiln, using the heat of wood burning to achieve the fastest drying effect of wood.

Of course, the drying in this is not to bake the wood directly on the fire, but to use a complex process to dry the wood in the kiln. (I won't explain it specifically here, as for the detailed information, please refer to, wood kiln drying process.) ）

Although there are some drawbacks to kiln-dried timber this way, it is currently the best solution for wood drying and the fastest way to provide timber for the construction of seagoing vessels.

At this point, all the problems of the shipyard have been solved, and the wood can be taken nearby, after all, Quanzhou is Fujian, and there is a lot of wood in Fujian, which can be used to make sea ships.

It is completely self-sufficient.

Everything on the beach is busy in an orderly manner, and from time to time there will be craftsmen recruited by Wei Dayong from Quanzhou Mansion to join it.

The whole construction site, overlooking from the sky, is like a huge ant nest, and people are like the worker ants on this nest, each with his own work and responsibility.

At the same time, under Li Mu's order, the Muhai joined this huge construction site, and transported the timber needed from other log cutting sites in Quanzhou to the shipyard by sea.

This also made the workers on the construction site shocked by the strength of the twenty cyborgs, after all, anyone carrying a whole log surrounded by two people, walking back and forth between the Muhai and the construction site on the ground, would be shocked.

If the shipyard is the most time-consuming and labor-intensive, then the salt drying plant is the first to be completed among these construction sites.

When all the cement pools of the entire salt drying plant can be put into use, Li Mu immediately asked people to fill the cement ponds with seawater, and then it depends on whether God can give it or not.

Time and intense sunlight will gradually evaporate the water in the seawater, revealing the non-evaporable part of the water, including salt.

The next step is to deal with the problem of mother liquor, when the seawater evaporates to a certain concentration, it is no longer drying salt, at this time, the salt and the mother liquor can be separated.

What is separated from it is snow-white sea salt, and then after some processes, it can be turned into high-quality snow salt from Datang.

Its meaning is as white as snow.

Handed over the process of drying sea salt to the servants of the Viscount's Mansion, Li Mu didn't care about the production of sea salt, he needed to wait until the sea salt came out to check.

During this time at the beach, Li Mu felt that his skin was tanned.

You need to rest, and you will talk about it until the sea salt comes out.

A few days later, Mei'er held a tray with a brocade pat and trotted into Li Mu's tent at the construction site, with a happy face.
