"The so-called steep gate is actually a large sluice gate, which is usually built in the steep part of the river. It consists of two high walls along the river and two gates blocking the river, forming a thing like a large room. It can be built individually or in groups, depending on the terrain.

If the boat is going upstream, first open the lower gate to let the boat in. After closing the lower gate, open the upper gate to release water to raise the water level inside the steep gate. As the water level rises, the boat will also be lifted up, so that the boat can reach upstream.

The situation is the opposite for ships going downstream. The Lingqu Canal is located at a high altitude, so many steep gates need to be built. Although winter in the south is also a dry season, there are always places that receive rainfall. After building more large reservoirs to store water, navigation can still be guaranteed. "

The fleet was approaching Lingqu Canal, and Wang Zhen introduced the steep gate of Lingqu Canal to Li Xian and other little guys.

Li Dan's eyes lit up when he heard this, and he asked, "Did you also invent the steep door, sir?"

Wang Zhen shook his head and said with a smile: "This was built by the ancient sages in the pre-Qin period."

Li Dan asked with some regret: "It's been so long, why didn't they build a steep gate in Chang'an?"

Zhang Gou explained, "Don't worry. We have already explored the coastal waterways at the beginning of this year. The sea ship workshops have already started a large number of operations. In the future, big merchants will switch to sea transportation, and small merchants will use Lingqu. With this diversion, there will be no problem."

Hehe, what a great idea to reject all schools of thought and respect only Confucianism. I have studied Confucianism for hundreds of years, but I don’t know what I have learned. In the end, I have studied so much that I have migrated to the south, and I have become a two-legged sheep. "

"Hehe, I can't say I'm uneasy, I'm just a little dazzled."

"This world is changing so fast, I am a little unsure."

“This is a bit too much.”

"Your Majesty, are you feeling uneasy?"

"No." Fang Numa explained, "The model of the big iron ship is a small iron ship. It was very small at first, but after making it several times, the current model is as big as a fishing boat and can also be launched into the water.

Fang Numa nodded, "That's about right. I have a large model of a big iron ship. We can play with it when the time comes."

"No, the frame of our sea ship is cast in steel, and the wooden planks and boards are fastened on top with fasteners. It is very strong. The gentleman said that this is just an emergency expedient. In the future, the whole ship will be made of steel, which will be even stronger."

To be honest, Confucianism really doesn't need so many people to spend so much time studying it. Wouldn't it be better to read more encyclopedias? At least it will be of some help to your life, what do you think, Your Majesty?"

After Mr. Wang came to Lingnan, he developed many good things. The number of workshops in Bao'an County increased day by day, and shipping to Lingnan became more and more frequent.

This adjustment not only reduced flooding in the rainy season, but also increased water flow in the winter. Now the Lingqu Canal can handle large ships with a capacity of 1,000 tons in every season, which barely ensures the smooth flow of transportation in Lingnan. "

Li Xian looked at the densely packed boats in the Lingqu Canal and asked worriedly, "Looking at the current situation, it seems that there are not enough. Lingnan is becoming more and more prosperous. We still have to make plans early."

Wang Zheng's ten years of painstaking efforts have made the Yuzhou school stand out completely. At least as one of the four major disciples, there is no problem for him to comment on Confucianism.

Li Zhi had an unfathomable expression, Wang Zheng seemed to be smiling, and Wei Siqian simply covered his face and retreated.

The skills of craftsmen are just minor matters, while Confucian classics are the great principles. All the rich people have devoted themselves to studying the great principles, and the skills of craftsmen have been lost over time, so naturally they can no longer build steep gates.

Wang Zhen explained: "Because there were many things to do in the pre-Qin period, only the steep gate was built in Lingqu at that time. After all, building a steep gate still requires a lot of money and grain."

Fang Numa thought for a moment and explained, "The large sea vessels in the past were twice as long and twice as wide as our thousand-ton ships, but they were narrower and could carry three times as much stuff.

Xiao Yuehua laughed and said, "No, just like a big iron pot will float when placed on the water, a big iron ship must be the same as a big iron pot."

Li Dan looked at Fang Zhao and asked, "Is that so?"

Li Dan asked in confusion: "Is that so? Why didn't other dynasties build it?"

Li Xian and Li Xian were silent, Fang Zhao and Zhang Gou looked at their teachers with admiration, Wang Pingan and Xiao Yuehua looked at Wei Siqian, and Li Dan had a confused look on his face.

Li Dan asked curiously, "How big is the sea ship?"

So Mr. Li organized everyone to contribute money and built many reservoirs in the tributaries of Lingqu Canal to store water. He then cleared out the silt in Lingqu Canal and deepened the river channel.

This year, the master asked the craftsmen to develop a new large sea boat, which is even bigger, about 30 to 40 meters long, 50 to 60 meters wide, and more than 20 meters high. One boat can carry 100,000 dan of goods. "

Xiao Yuehua said with some disdain: "Tsk, models are all small, only kids play with models, I haven't played with models for a long time."

The exquisiteness of the Lingqu steep gate amazed Li Xian and other kids. When the boat entered the Lingqu, Fang Zhao introduced: "In the past, the Lingqu in winter could not carry a thousand-ton ship.

Li Xian raised his eyebrows and asked, "Won't a ship that big fall apart?"

"The world is changing every day, and people should also change with the world. It's a lifelong learning process. It doesn't matter if they don't change themselves, but it's a bit wrong for him to restrict his family members from changing.

Wang Zhen looked at Wei Siqian beside Li Zhi and raised his voice and said, "Because people think that the people of the world are scholars, farmers, merchants and artisans. Scholars and farmers are the foundation of the country, while artisans and artisans are menial servants. Among them, scholars are the most noble. Naturally, scholars look down on artisans.

After listening to Zhang Gou's explanation, Li Dan asked in disbelief, "Won't a steel ship sink in the water?"

Everyone looked at Zhang Gou, who nodded and confirmed, "If the wind and waves are not too strong, we can actually go sailing. The model is seven feet wide and two feet long."

Xiao Yuehua was stunned. "How can such a big ship be called a model?"

Fang Numa thought for a moment and explained, "Compared to a large ocean ship, it's just a model."

Listening to the conversation between the little guys, Li Zhi looked at Wang Zheng and said with a smile: "The ultimate goal of your Yuzhou faction is the borderland, the sea and the stars. Now the borderland has begun, and the sea has also been revealed. How is the research on the stars going, Chief Steward?"

Wang Zheng smiled bitterly, "If you want to explore something, the first thing you need is to see it within your sight. I can only barely see them now."
