Under the guidance of Xu Zizheng, Li Yu visited the shipyard that he personally participated in the planning. Since the date of construction, Li Yu has been here for the first time.

The four daughters of Xin'er, who were bored in Pyongyang, also came with Li Yu, curiously listening to the explanations of the shipyard's attendants and observing the different uses of the shipyard's facilities.

Yang Shiyan, who came from Youzhou some time ago, was even more inseparable from Li Yu.

Yang Shiyan, who is a childhood sweetheart with Li Yu and claims to know Li Yu very well, feels more and more unable to see through Li Yu as she grows older and knows what is going on. Judging from the fact that he set up a shipbuilding workshop and sent an expedition fleet to the sea, Li Yu was extremely thoughtful and prepared early.

As the great-granddaughter of Yang Gongren, the founder of the Tang Dynasty, Yang Shiyan, who was the queen of the former Sui clan, is not only beautiful and moving, but also smart and quick-witted since childhood.

has been by Li Yu's side for several years, although it is not clear what Li Yu is trying to do. But since entering Pyongyang, I have seen things that Li Yu had never known before, and then connected with some things I had learned about Li Yu in the past, and suddenly felt that Li Yu had a shocking plot hidden in his heart.

Yang Shiyan was curious to ask Li Yu about the exact purpose of what he was doing, but when she asked him just now, she knew that Li Yu would never explain it to her, so she could only write it down silently in her heart, looking at his subsequent progress from the perspective of a bystander, waiting for the day when the mystery was revealed.

Fortunately, Yang Shiyan did not know that Li Yu's commercial layout played a great role in supporting the soldiers of Andong's Goguryeo rebels, otherwise he would be even more surprised by the horror of the thirteen-year-old Li Yu.

Regarding the business empire that Li Yu has built up over the years and the force hidden in business, only a few people know about it, such as Xin'er, Cui Xuan, and Xue Jun.

Inspecting all the way, Li Yu saw that this shipyard, which was originally on the drawings, was becoming a reality little by little, and he couldn't stop being excited.

The Liaodong Shipyard is the largest of the three shipyards owned by Li Yu, and it is also the one with great expectations.

The Weihe Shipyard can only build some inland river flat-bottomed boats, and the Youzhou Shipyard is a small shipyard that mainly builds some new seagoing ships for testing, and has limited shipbuilding capacity.

The Liaodong Shipyard is where Li Yu really carried out large-scale construction of seagoing ships.

Liaodong Shipyard is located in the northeast of Duli Town, across the bay, which is exactly where the natural ice-free port of Arthur in later generations is located.

Surrounded by mountains, there is the Golden Mountain in the east and the Tiger Tail Peninsula in the west, and there is a long and narrow waterway connecting with the open sea. The harbor is well concealed and windproof. The depth of water in the port is a natural base for shipbuilding and the establishment of large ports.

Li Yu continued to use the title of later generations, named the port where the shipyard was located Port Arthur, and built two ports in the east and west according to later generations.

Liaodong Shipyard is located in Xigang, with Baiyu Mountain to the east and Longhe River at the bottom of the mountain. The shipyard is located on the flat land on the west bank of the Dragon River, and the east and west banks of the mouth of the Dragon River are the West Port Wharf.

Donggang port conditions are the most superior, in the middle of the north, south and east mountains form a large area of mountain basin, just because there is no big river in this sea, it is not conducive to the construction of shipyards, so this place is used as a commercial port for cargo distribution and ship docking in Liaodong.

Li Yu set up the shipyard here, in addition to the excellent port conditions, it is to rely on the iron ore and high-quality wood of Liaodong to solve the problem of materials needed for shipbuilding.

The best wood for building seagoing ships is hardwood grown in tropical rainforests, which is currently only produced in the sparsely populated Qiongzhou, and hardwoods from Lingnan, Jiangnan and southern Jiannan Province, which are located in the subtropical region.

Pine wood is actually a relatively poor kind of board used in building seagoing ships, and its corrosion resistance, insect resistance, and wood stability performance are not as good as subtropical and tropical hardwoods.

At present, the shipyard in Liaodong uses temperate trees such as tall Korean pine, spruce, and larch that are more than 100 years old cut down in the primeval forests of Liaodong, which makes Li Yu a little dissatisfied. But at present, it is not cost-effective to transport good shipbuilding timber from the south to the north, and it can only be done with pine wood.

After Zhang Qin returned with his fleet, Li Yu planned to quickly organize his men to move south to occupy Taiwan, that is, Ryukyu, and establish a new shipyard in Taiwan to use the local high-quality hardwood.

The Liaodong Shipyard used all the new technologies currently in Li Yu's hands during its construction.

Many of the hardware facilities of the port wharf, roads, and shipyards are built with high-quality cement produced by Xuanji Commercial Bank, and the dock invented by Zhang Ping in the Northern Song Dynasty hundreds of years later is also used. Now there is nothing to do with Zhang Ping, and history will remember that it was Li Yu who invented the shipyard that had a revolutionary impact on the global shipbuilding industry.

On the west bank of the Longhe River in Xigang, only ten zhang away from the mouth of the sea, there are docks that have not yet been built. The two largest docks can build huge ships carrying 20,000 stones, or 1,000 tons. (In the Tang Dynasty, the size of the ship was measured in the weight of the "stone", and the "material" was not used until the Song Dynasty) The smallest dock could build a ship of 50 tons.

The dockyard is a large rectangular pit dug in the ground and hardened with cement. The size of the pit is based on the size of the ship for which the pit was built. After the ship is built in the dock, open the water inlets in the dock piers on both sides of the dock mouth, divert water into the dock to make the ship float, and then open the water retaining dock door at the dock mouth, and then pull the water into the Dragon River and then enter the sea by the slender man.

The shipyard is planned to be very large, and the east port is surrounded by two mountains, that is, the vacant land is to be used as a port and a dock to be built, and the area is not enough. Only the west bank of the Longhe River has enough space with the help of the Longhe River, and Li Yu pulled the Liaodong shipyard here first.

After the Liaodong shipyard is fully completed, it can build a thousand-ton giant ship, Li Yu pouted after seeing it, some shipyards in the south of the Yangtze River can build a two-thousand-ton giant ship.

According to records: during the reign of Xuanzong Tianbao of the Tang Dynasty, the Anhai ship built in Quanzhou was "a silver ship with a board of 15 grids, which can store goods as much as 2 to 40,000 stones." "Fifteen compartments, i.e. fifteen bilges.

It seems that a new round of planning for the Liaodong Shipyard has to be put on the agenda.

Li Yu really thinks that the weight unit "stone" is troublesome, and one stone in the Tang Dynasty is 53KG. For the sake of calculation convenience, it is uniformly stipulated that the weight unit stone of Yanwangfu and Andong Duhufu all adopts one stone as 50KG, which is equal to 0.05 tons, and officially introduces the greater weight unit of ton.

For the size of the ships built, it will be calculated in tons.

In the next ten years, the Liaodong Shipyard will take on the main shipbuilding tasks, so Li Yu originally planned the Liaodong Shipyard very much, so that now only five dry docks have been completed to build ships.

After the Liaodong shipyard is completely completed, there will be 20 dry docks, lined up along the west bank of the Long River, and the construction of 20 ships can be started at the same time. If necessary, after the shipyard is completely completed, Li Yu will increase investment and continue to expand the scale of the Liaodong shipyard.

Climb the shipyard to build on the west bank of the mouth of the Dragon River, and you can see the entire Port Arthur.

To the north, six docks have just been completed and will be ready for use in a few days, leaving nine docks, two of which are of the thousand-ton class. Thousands of slave laborers captured on the battlefield of Liaodong, under the watchful eyes of the sharp-eyed overseers with whips, nervously endured the cold wind to dig and build. There were also many heavily armed and skilled soldiers on the construction site, watching their every move.

With the five docks put into operation, the three docks for the construction of the three ships needed for the expedition of the Hololang Sea, the craftsmen directed the slaves to carry the materials in preparation for the construction of new ships. In the other two docks, two ships are half-built, and presumably they will be launched in a month or two.
