The main island of Yangsan is the base camp, and various workshops are located in Chaojiazhuang. Such as garment spinning, kiln kiln, sugar mill, oil mill and so on. It's just that the scale is larger or smaller, and there is more income in addition to self-sufficiency.

After leaving the military factory, Chao Gai went to these factories and workshops one by one, and in addition to visiting and giving guidance, the purpose was to distribute Jeju Island specialties, comfort the hired workers, listen to and adopt opinions, and improve the system.

Along the way, you can also see horse ranches, large terraced fields, people are jubilant, busy for the coming year's farming, it is said that the yield of crops per mu is several thousand catties.

The island is small, but it is full of life!

Chao Gai took Han Shizhong, Yutai and other generals to run around, and the group ate a roast whole sheep at the pasture, and then continued to inspect Liangshan Island.

Lou Minzhong, Zuo Shangshu, was very capable, and took over Liangshan Island from Wen Huanzhang, and many self-employed people such as handicrafts were born among the people, opening shops, such as selling snacks, or fresh fish and dried fish and shrimp, forming a small trading market in the designated area......

Chao Gai agrees with this!

The group came to the shipyard by the duckbill beach, which is also the most important place except for the military factory. The location is located on an island adjacent to the main island. There are more than a dozen large docks along the coast of the island, all of which belong to the shipyard area.

To this end, Chaojiazhuang hired old shipbuilders from Deng, Lai, Ming, Yang and other places at a high price, dug the foot of the wall from various shipyards, recruited apprentices who were good at carpentry and brains, and the shipyard had more than 3,000 people, divided into more than ten teams.

Together with the sailors who helped with the launch of the sea trial, the number of shipyards was 5,000. There are two or three hundred people busy in each large dock, responsible for the construction of large sea vessels, as well as supporting assault boats and lifeboats.

Meng Kang was already good at building large river boats, and he had the assistance of experienced masters. Coupled with the advanced concept proposed by Chao Gai.

Although he did not know about ancient ships, he could only mention points according to the structure of ships in later generations, such as enhancing buoyancy, punching threads, and riveting techniques, but he knew the mortise and tenon structure of Ming Dynasty ships, and discussed and tried many times.

Drawing of drawings, assembly of various parts, etc.

It is the inspiration of the lid, the mortise and tenon structure, and the rivet technology that solves the problem of fixing the boat. Improve the efficiency of shipbuilding, shipyards have repeatedly created miracles.

The hull is stable, and the ship can only be built larger. Due to the limited environment of the water berth. A large number of craftsmen settled in the shipyard of Laizhou Naval Base for the fireworks ship.

In addition, the shipyard on the main island of Yangshan produces at least 20 thousand-class sea vessels every month. In other shipyards, it is impossible to do so.

In the past few months, Chao Jiajun has several large naval ships, most of which are made by shipyards.

When Chao Gai led the team to arrive at the shipyard, Meng Kang, the jade banner pole, got the news in advance, and took the shipyard management personnel early to meet and wait on the shore. Seeing the team coming from afar, the enthusiasm of the attitude is embarrassing.

Not only this man, but in the eyes of others, Chao Gai can be civil and martial, lead troops to fight, brew and cook, forge and burn kilns, and also know how to ...... ships.

Surrounded by everyone, Chao Gai entered the docks to inspect, he had been to the shipyard before but did not have an in-depth understanding, but now he came in person, and he had a deep experience.

During the Qin and Han dynasties, China's shipbuilding industry was ahead of the world, and the Song Dynasty ushered in a peak of development, and the emergence of advanced technologies such as watertight warehouses, compasses, and balanced rudders laid the foundation for navigation and transportation in the Song Dynasty.

Before the riveting technology was used, the sea ships of the Song Dynasty did not have a single nail. It is conceivable that the Mulan Boat can be built just by the grooves of the wood and the wood, and the skill is exquisite, which is unimaginable to future generations.

The main thing is the knowledge of building ships!

In the construction of ships, especially large ships, there is a lot of attention paid to the selection of wood. For example, it is not necessary for ancient trees to be suitable for shipbuilding, nor is it possible to use trees after cutting them, they need to be dried or baked for a long time before they are suitable.

Ancient ship wood can withstand the erosion of seawater, wind and waves for decades or even hundreds of years, which has a lot to do with its materials. There are many types of trees used as large sea vessels, and most of them are high-quality tree species with high density, high hardness, oily or waxy texture.

There are mainly Pontianak wood, catalpa, teak, pineapple lattice, iron pear wood, etc. In addition, sea vessels are large in size, so logs generally grow to more than 100 years. Its average diameter can reach several meters and its height is more than several tens of meters. After decades of immersion in seawater, the waves have washed countless times, becoming more and more tough, wear-resistant, waterproof, insect-proof, anti-corrosion and other effects.

Chaojiazhuang buys timber from caravans from all over the world, including those shipped from Dali or Goryeo, Siam and other countries, which is a large monthly expense!

However, it's all worth it! The shipyard did not disappoint the big guys. The dock is divided into several levels, and the water is under the openwork platform. Hundreds of people were busy, the roar shook the sky, and the people were constantly coming in and out. There are teams responsible for the side of the ship, teams responsible for the stern, and teams standing on the high platform below to be responsible for the bottom of the boat, each performing its own duties and a clear division of labor.

The masters led the apprentices to use red pen scribing, saws, iron chisels and other tools to teach by word and deed, reprimand and even hands-on, cutting wooden planks according to the requirements of the drawings. ...... the holes are drilled, and the planks are spliced together to form a boat......

This shipbuilding industry reached its peak during the Ming Dynasty.

Unfortunately, the Qing Dynasty gradually fell behind and did not adapt to the continuous improvement of the general environment. Such technologies gradually declined until they died out in the new era.

Chao Gai walked between the various docks, witnessed the busy scene of the craftsmen, watched the process of forming thousands of seagoing ships, and listened to Meng Kang and the masters explain the key and the precautions for ship construction.

Inexplicably thinking of the humiliation at the end of the Qing Dynasty, I can't help but sigh for the calamity of the nation. Because of his appearance, the drawings and paintings of the Liangshan Shipyard gradually became popular, the master no longer cherished the broom, and the cabin space was increasing......

The wisdom of the ancient Chinese is impressive, but what they lacked was cognition. After the inculcation of advanced ideas, the shipyard will create more miracles!

During the Song Dynasty, ships were not only large in size and varied, but also in the presence of merchant ships, and the trade routes once reached Southeast Asia and the Middle East, selling the precious ceramics and silk goods of the Northern Song Dynasty to all over the world.

The prosperity of the Song Dynasty's maritime trade was seriously related to the "lack of territorial expansion", which caused the Song Dynasty to attach importance to overseas markets, and it is recorded that more than 50 countries such as Japan, Goryeo, Boni, and Dashi were all trading partners of the Song Dynasty, and the farthest place could even reach Africa.

It's just that the ships are too heavy, the draft is deep, and the carrying capacity is not satisfactory. A magnolia boat more than 20 zhang long, like a behemoth, can only carry 20,000 materials, which is 12,000 tons. However, during the Ming Dynasty, the carrying capacity of the same type of ship was 50,000 or 60,000 tons.

In addition to the different ship structures, the most important thing is that in order to cope with the harsh maritime environment at that time, the ships of the Song Dynasty generally shaped the decks and cabins to be relatively thick, so the carrying capacity was not enough.

If it is used to transport troops, it will lead to a serious shortage of bearing capacity of the hull, and some problems will arise when encountering strong winds and waves. This point has been encountered many times by the expedition team, and the goods carried each time are proportional to the personnel, and even if there is enough space, they will not be carried blindly.

As a result, the actual carrying capacity is far greater than the ship itself.

So, the defects of such ships are something that shipyards want to improve.

It was impossible for Chao Gai to follow his laurels and inherit all the weaknesses of the Song Dynasty's ships. Today's shipyards, in addition to using new processes to build new ships.

There are several docks dedicated to the improvement of river boats by elite craftsmen. For example, the old-fashioned building ship, the overall reinforcement, the addition of watertight cabins, and the addition of various facilities.

For most of the six months, regardless of the cost, the effect is remarkable.

The floor of the same type of boat, the deck thickness is thinned and the rubber is used. The internal cabin has been enlarged, and the carrying capacity has been increased by at least 50%. The center of gravity of more than a dozen renovated building ships has been improved, and the performance has been greatly improved.

In particular, ships resembling sail battleships, which are being built in full swing. An eight- or nine-meter-long ship that is about to be completed combining China and the West. Just by waiting for the completion and launching, it will be able to provide experience for the construction of new ships.

Various ideas were conceived, such as the hull of a ship equipped with steel ramming angles, which could be inlaid with iron plates composed of iron sheets. How to increase power, boat speed, etc. These are like beacons for the masters who have built ships all their lives.

As long as you have the right direction and the will to study.

The shipbuilding industry will keep pace with the times and continue to move towards the peak.

Chao Gai believed in this, so he improved the treatment and status of craftsmen, and invested large sums of money in military factories, shipyards and other places to strive for innovation.

"Brother Meng Kang, the shipyard has been handed over to you. Dig out more talents that can be created. Don't be afraid to spend money, dig into the wall, recruit talent, and hire with a high salary. Some ideas can also be discussed, and in the future the Navy will set sail here. ”

Chao Gai has a positive attitude towards Meng Kang's craftsmanship and management ability. It's just that before leaving, the other party chatted for a while and told him to leave.

Meng Kang, the jade banner pole, was very grateful to Chao Gai, if it weren't for the solicitation of this Shandong Heavenly King. I am still drinking Ma Chuan, robbing my house, and I have nothing to do. Where will it be like now in charge of the shipyard, with thousands of people under his command.

This man with a white face and a clean body grew up, looking at Chao Gai's back, his eyes were firm, he nodded silently, and swore in his heart that he would live up to his trust.

Chao Gai returned from the shipyard and originally wanted to continue to inspect the barracks. After all, as a leader, you have to show up in the army, which is conducive to controlling the army.

I just saw that the sun was getting red in the sky, so I dismissed my idea.

Chao Gai suddenly remembered something, turned around and ordered the generals who followed: "Shizhong, Guo Zi, you go to the barracks and go to the military factory to carry weapons and equipment. In addition, there was a shortage of commanders in each army, so two hundred guards were selected and decentralized. ”

"Yes, I'll understand!" Han Shizhong, Guo Sheng nodded.

"In addition, Yu Tai led a hundred people to follow, and you led the soldiers of the trapped army to board the ship for training. That Zhao Tan is not very honest, so he will be honest when he beats him. ”

"Brother, don't worry!" Everyone was eager to try it.

Only Sai Qin Qiong Yutai covered his face, and this kind of good thing didn't have his share. Chao Gai did not favor one over the other, and promised to take him to Bianliang City to play in the future. Several generals were sent out of the barracks and returned to the family compound alone.

Under the corridor, Li Qingwan, Master Li, and Li Qingzhao were basking in the sun on the recliner, talking and laughing......
