After Cai Jing took office, the first thing he did was to cry and make a fuss and ask Li Shuanshuo to come to Lianghuai Road to help him.

Before Su Song resigned, he also suggested that Li Shuanzhuo should replace him.

Haizhou is a hub of sea and land. If the governor sent to Haizhou does not understand science and engineering, he may not be able to do anything.

Finally, the imperial court agreed to Cai Jing and Su Song's request and asked Li Shuanshuo to come with the title of Minister of Works to serve as the prefect of Haizhou.

Li Shuanzhu was six years older than Su You, and was now over fifty. By chance, he became the third-rank minister of the Song Dynasty. He felt that it was inappropriate for him and kept clamoring for a foreign appointment, but he took advantage of his wishes.

After Li Shuanshuo arrived, the most comfortable person was Cai Jing. Cai Jing also followed Su You's example and boldly decentralized power. One of them was in charge of industry and the other was in charge of finance and civil affairs, making the Lianghuai Road prosperous.

Su You smiled and held up his hands to Li Shuansha: "Yuan Chang is right, the most important task for brother Shuanshao now is to pass on his skills to future generations."

Cai Jing said with a smile: "When we arrive at the harbor soon, Ming Gong will take a good look at Brother Li's generosity!"

After getting off the carriage, Su You saw the railway track and cement trestle stretching far into the sea, and couldn't help but clasped his hands together: "Brother, you've done a great job!"

The railway can drive the train directly to Haizhou Port. Haizhou Port is actually a large bay connecting the land with a long and narrow island in front.

The location of the island is just right to withstand the northeasterly wind coming from the sea. The northern end of the island is built with stone cages to create a dike to block the sea tide from the north.

There are also two seawalls at the southern end of the island. The seawalls are staggered and there is a passage in the middle. Ships must make an S-shape to enter the harbor.

This design can also block the impact of the tide from the south and turn the entire strait into a peaceful harbor.

The railway was built along the northern embankment to the island opposite. On the side of the island near the bay, there are eight berths extending into the bay, and there are also three docks.

Next to each berth, there is a tower-like machine - a crane. However, unlike the single arms of later cranes, these cranes are like scales, with one long and one short arm.

Because nowadays they are all sailing ships with tall masts, gantry cranes are not suitable for placement in ports, and because the cranes can withstand mechanical strength issues, in order to prevent them from capsizing, Li Shuansu invented something that astonished Su You - the balance crane.

The balance crane is a device that uses the principle of the balance and uses counterweights to always fix the center of gravity of the crane's boom on the vertical line in the center of the tower base, preventing the crane from overturning.

Moreover, the tethering design is very clever. The stone anchor used for balancing is connected with a rope and placed on the turntable at the bottom of the crane. When the upper part of the crane rotates, the turntable below will also be mobilized by the gear and rotate accordingly without affecting the operation.

When the stone anchors need to be balanced, the workers on the tower only need to shake the handle and let a group of stone anchors hang in the air, which can play a balancing role. As the hoisted goods on this side increase, the stone anchors on the other side will continue to be lifted.

Keep the crane balanced at all times.

Li Shuanzhu introduced to Su You: "Master, the tide in this area rises and falls by more than five meters. With this set of crane trucks, ships coming to the port do not have to wait for the tide to be right before they can load and unload cargo, which saves a lot of money."

time."

"The goods can be transported by rail car and horse-drawn to the warehouse next to the port station, and then sent out by train."

Su You nodded, the old man's vision was still vicious, the importance of Haizhou was to be able to receive things from Dongshengzhou.

Coming from Songcheng, Japan, this is the most convenient port.

Now it has become the most important port that protects and responds to the entire Beiyang of the Song Dynasty and controls the Liao Kingdom, Korea, and Japan.

Here and Dengzhou are two important havens that back up each other. When the northeast wind blows from the end of winter to the beginning of summer, sea ships can go to Haizhou Port to take shelter; when the southwest wind blows from the end of summer to the beginning of winter, sea ships can go to Dengzhou.

Go to the harbor to take shelter from the wind.

No matter what, it is protected by the Denglai Peninsula, which is a unique blessing.

Of course this is for civilian ships, but the military port is two other better ports - Jiaozhou Bay at the foot of Laoshan Mountain in the south, and Weihaiwei, the new guard station at the foot of Rushan Mountain, in the north.

The important connection between Haizhou and Dongshengzhou is Songcheng. Gao Gong Hui just returned from Songcheng, and Su You also focused on the situation there.

In addition to serving as a colonial seaport during the Song Dynasty, Songcheng was also an important concentration center for local gold, silver, copper and coal. Nowadays, tens of thousands of households were gathered there. By supporting the Taira family, the Song people gained increasingly stronger control over Japan.

Today, the ruler there is Zhang Sidao, the eldest son of Zhang San and Hira Shinso. Because Zhang San is said to be the reincarnation of Kun in Japan, Zhang Sidao also has a Japanese name, Taro Meikai.

Zhang Sidao studied under Zhang Tianshi since he was a child. Although he is half Japanese, he is actually a Song Dynasty person at heart.

In order to control Japan, after the imperial court recalled Gao Gonghui, in accordance with the vassal system, Zhang Sidao was granted the title of "General Henghai" to guard Songcheng.

The emperor is now using the Taira family to compete with the Hara family for control of Kyoto. After Zhang Sidao arrived in Songcheng, the emperor immediately appointed him as one of the top five, Izumo Shou, and Kinninshi, and assigned Songcheng to the Taira branch.

Minghai was his surname, and he was given the name Minghai Morihito, and he became independent from the Taira family.
