Little did people know that as early as the Qin Shi Huang period, China had already used steep gate technology to raise and lower water levels to connect ships upstream and downstream.

An international friend once lamented: "It is not the father of canal sluices, but the grandfather and great-grandfather of canal sluices!"

The Lingqu Canal, known as the Great Wall of the North and the Lingqu Canal of the South, has the earliest sluice in the world.

The Lingqu Canal connects the Li and Xiang Rivers, which is equivalent to connecting the Pearl River Basin with the Yangtze and Huaihe River Basins. Together with the canal of the Sui Dynasty, theoretically, even the Yellow River Basin is connected.

This time, Wang Zhen's route to Lingnan is to enter Dongting Lake from the Yangtze River, turn to the Xiangjiang River, then pass the Lingqu Canal to the Lijiang River, and the final destination is Bao'an County.

Since Wu You was preparing to relocate the people of Yuzhou, Wang Zhen of the fleet naturally could not wait any longer.

But Wang Zhen didn't mind. There were only tens of thousands of people anyway. The river water was clear and calm, so they could just tie some bamboo rafts together and go down the river. When they reached Dongting Lake, there were plenty of boats available for rent as long as they had money.

Cheng Bokang sighed and said, "You young people are so good that you set such ambitious goals. We can't do that. We can just struggle in the Tang Dynasty for a while in this life, and that's enough."

"Ever since the appearance of the Grand Steward, the world has been constantly changing. Even though I have always stayed by his side, I always feel overwhelmed. Take food for example. In the past, I always heard of people starving to death, but in recent years, I have heard that more people have died of bloating than of starvation."

"It's not that it doesn't count, it's just that the power is not great. The winner of the four great borderlands this time should have a greater reward. The master once told us several goals, namely the borderlands, overseas, and the stars.

But what kind of renovation is not excessive? This trip to the south must rely on the power of the aristocratic families to hope to develop the entire Lingnan as soon as possible, but the aristocratic families only consider their own family, and the strength between winning over and suppressing needs to be considered more carefully. "

Wang Zhen said with disdain, "The area of ​​the Tang Dynasty alone is not enough for us in Yuzhou. Even if we add the known places in the west, it is only enough for our generation at most. What about the people who come after us? Therefore, it is not too early for us to look overseas now. Let's just explore the way for those who come after us.

The teacher taught us that we must go out to find a way out. If we just stay in the Central Plains, we will always be trapped in the cycle of rise and fall. The conservative Confucianism is not acceptable."

It didn't work the first time, so after clearing the boulders the next day, they blasted it again, and then the third day. After three times, they finally removed the boulders from the river.

Wang Zhen looked at the clear and calm river and murmured, "Teacher often said that the general trend of the world is like a big river and cannot be changed lightly. A gentleman should act in accordance with the trend, so that he can achieve twice the result with half the effort. However, a slight adjustment is still possible.

After a while, there was a loud noise in the river, it was really like the sky falling and the earth splitting. I was standing on the shore at that time. When the loud noise came, the whole river bank was shaking and people could not stand steadily.

Afterwards, the chief steward measured the depth of the surrounding riverbed and spent a month filling many stones in the deep places. Only then did the place become completely stable. Afterwards, the chief steward explored along the river again and spent two months repairing the entire river channel of the Three Gorges.

The secret method of blasting the boulder was used by the guys in the gym at night. I don't know the truth. I only remember that after they were busy around the boulder for more than half an hour, they rowed their boat down the river.

After using the secret method to blast the huge rock away, he was busy for another three months, and with great difficulty, he filled up the riverbed, which led to the peace of the river today. It's a pity that I was still young at that time and didn't come to see your feat. Uncle Cheng, can you tell me about the grand occasion at that time?"

"Hey, why bother?" Cheng Bokang said nonchalantly, "Just do your best in everything, the result is not important. Anyway, with my ability as the chief steward, no matter what you do, I will help you settle it in the end."

Cheng Bokang looked very proud, smacked his lips and said, "Back then, I followed the chief steward here. During the day, the chief steward asked the craftsmen to drill holes in the huge rocks in the river.

If any of us can manage the borderland best, then the overseas land, hehe."

"There's really nothing much to say."

"Hehe." Wang Zhen narrowed his eyes and smiled, saying: "That being said, we still have to show our own value, right? Sir, you have a bamboo stick, it's really tempting."

The stars are too far away, even the master sighed when looking at them, but the borderland and overseas are known places. The borderland is easy for the master, so he will leave it to us.

I just asked Cheng Bokang to help transport a few ships of supplies. When passing by the Three Gorges, looking at the still calm river in front of him, Wang Zhen sighed: "I heard that there were often accidents here in the past. Six years ago in the winter, Mr. brought 10,000 craftsmen here.

From now on, as long as there is no strong wind or flood, there will be basically no accidents when sailing on the river. The stability of the river is the foundation for the improvement of our imperial farm in recent years, and the stability of the river is all due to the efforts of the great steward in the past. "

If the steward had not designated a safe place for us and let us stand on flat ground, many people would have been in trouble. Even so, many people fell.

Hehe, many guys were so scared that they peed their pants, and one person was even scared to death. However, the steward said that the man was scared to death because he had a heart disease. I remember that at least half of the people knelt down and prayed to God for protection.

"Haha, the so-called world of the Tang Dynasty is just like this. Let's not talk about other things. Just the known places in the west, I don't know how many Tang Dynasties are as big as this."

"Hehe, as long as you keep changing for the better, there's no problem. No matter how you change, it will be for the better."

"But it's not good to change too fast. I heard that His Majesty is often so busy that he has a headache. He is planning to form a staff group like that little guy Wu You."

"Oh, the staff group is not like that. Empress Wu holds half of your majesty's power. Even if you form a staff group, it will mostly be given to Empress Wu to lead."

"It's okay for us to say this here, but you can't say it anywhere else."

"It doesn't matter much. It is well known that His Majesty trusts Empress Wu. After all, his son may rebel, but his wife will never do so."
