Please ask me to be the emperor

There is a saying that "it's hard to sleep when you're sleeping alone", but it's actually hard to sleep when you're sharing a pillow.

In fact, before Li Xiang arrived, Zhang Shun's favorite woman was none other than the Red Lady.

But later on, Li Xiang and Liu Rushi competed for favor, and Zhang Shun had more and more women. The two of them got together less and separated more, which was quite different.

Fortunately, Zhang Shun is now becoming more and more successful, and Zhang Shenyan, Lu Weiqi, Song Xiance, Hong Chengchou and others are sharing his worries. The red lady no longer has to sit in the rear as before, so she travels with Zhang Shun this time.

The red lady's child had been handed over to Jian'er to take care of her before her trip, so she felt free from worries.

That night, the red lady relied on her "seniority" to squeeze out the two daughters Ma Yingniang and Wang Qiying, and finally got her wish of "single pampering in the harem".

One of the two is a hero among men, and the other is a husband among women. Naturally, they will not obey the other, so they will fight fiercely.

When you are sweating and your muscles and bones are soft, you will know that the east is white!

Zhang Shun squinted his eyes for a while, but he didn't feel sleepy. He simply got dressed and breathed in the fresh air without pollution in his life.

Not long after, everyone got up one after another, and Zhang Jinyan, the magistrate of Sanyuan County, also hurriedly arrived.

So, Zhang Shun had a hasty breakfast and left the inn under the leadership of Zhang Jinyan.

In order to save time, Zhang Shun did not take a detour to Jingyang County this time. Instead, he set off directly from Sanyuan and drove directly to Dihukou, Zhongshan West.

The so-called "Zhongshan West Dihukou" is the diversion point of the original Zhengguo Canal, which is also the so-called head of the canal.

Sanyuan is fifty miles away from Hukou. Although everyone set out early, it was already noon by the time they arrived.

"Your Highness the King of Qin, this is the entrance of Zhongshan West Dihu." Zhang Jinyan pointed to the front for Zhang Shun.

"This side of the Jinghe River is called Zhangjiashan, and the other side of Liquan is called Jiuwei Mountain."

"Both these two mountains are the remnants of Zhongshan Mountain. They stand opposite each other and form the mouth of the valley."

"Jingshui comes out of the mouth of this valley, from narrow to wide, shaped like a gourd, so it is called Hukou."

Zhang Shun followed Zhang Jinyan's finger and saw that the mountain was indeed like this. He couldn't help but asked curiously: "What does this Zhengguo Canal have to do with Guanghui Canal?"

"Your Majesty, King of Qin!" Zhang Jinyan arched his hands upon hearing this and said, "In the past, King Qin opened the Zhengguo Canal to connect the Jing and Luo rivers. This was the beginning of all canals."

"In the second year of Taishi in the Western Han Dynasty, Bai Gong, the official of Zhao Zhong, built a new canal. The water of the Zhengguo Canal was directed eastward and poured into the Wei River at Yueyang, which was called Bai Canal."

"The two canals are called two, but they are actually one, so they are called Zheng Bai Canal."

"There is a ballad from time to time that goes: The State of Zheng is in front, and the Baiqu rises behind. Lifting letters becomes clouds, and breaking down canals becomes rain. A stone of Jingshui, with dozens of buckets of mud, and irrigation and excrement, grows my millet, cloths and feeds the capital, and has the mouth of billions !”

Not to mention, this Jinyan has a good singing voice, he can sing a few lines casually, and he has quite a lot of skills.

Zhang Shun didn't know that in history, this guy was one of the people who had to bring ten singers with him when he was sent to Ninggu Pagoda. He had a lot of research on songs, and of course he had a certain level of singing.

It's a pity that except for the red lady who can sing a few folk songs from northern Shaanxi, none of the others who are accompanying her are knowledgeable about music theory.

But the red lady also stayed at Jianzhong Station to rest today and did not come because she was "tired from the journey".

So Zhang Jinyan sang a few lines a cappella and found that no one even responded, so he had to stop in embarrassment.

"Go over and have a look!" Zhang Shun, who had no sense of aesthetics, didn't know that he had missed "Jacky Cheung in the late Ming Dynasty", so he just ordered to himself.

Not long after, everyone came to the bank of Jingshui River. Zhang Shun took a closer look and found that there were two canal mouths on the bank of the rolling Jingshui River, both of which were more than ten feet higher than the surface of the Jingshui River.

"What's going on?" Zhang Shun couldn't help but wonder, "The mouth of the canal is so high. Is it possible to build a dam to block the water?"

The reason why Zhang Shun had the confidence to come was because he had participated in the construction of a dam in his previous life and felt that it was not feasible. Building a dam on the Jingshui River would solve all the problems.

"I don't know what the dam the King of Qin mentioned is?" Zhang Jinyan shook his head after hearing this and said, "From what I can tell, the mouth of the canal here was originally lower than the river surface, but it has only been lowered for thousands of years. The river surface has sunk, so that the mouth of the canal is high, covering the There is no doubt that Guanghui Canal will benefit today!"

Zhang Shun frowned when he heard this. He had heard Zhang Jinyan talk about the sinking of the river several times. What was going on?

He stared at the rolling Jingshui for a long time, and suddenly he realized: Could it be that the river was flowing downward?

In fact, if Zhang Shun hadn't been engaged in construction work in his previous life and happened to participate in the construction of a small river dam, he would never have imagined the mystery.

This is also true. It is precisely because the Jingshui River flows out of the valley and flows so fast that it will continue to erode the river bed, causing the river surface to gradually decline.

By later generations, the water diversion entrance of Zhengguo Canal was already five to seven meters above the Jingshui River, so much so that some people once believed that the world's earliest river dam appeared in China as early as the Warring States Period.

"Let's go upstream and take a look at the head of Guanghui Canal!" Zhang Shun thought for a long time and felt that there was nothing he could do, so he couldn't help but order.

So, everyone walked along the bank of Jingshui River towards Zhangjiashan.

Not far away, he saw the mouth of another diversion canal. Zhang Shun couldn't help but asked: "Is this the head of Guanghui Canal?"

Unexpectedly, Zhang Jinyan shook his head and said: "This is the water diversion entrance of Sanbai Canal in the Tang Dynasty!"

So everyone walked several hundred steps again until they saw the mouth of a canal again.

Zhang Shun learned his lesson this time and couldn't help but ask: "Why is this a canal?"

"This is the Lifeng Canal of the Song Dynasty!" Zhang Jinyan sighed and said, "The mouth of Zhengbai Canal was abandoned, and Sanbai Canal was re-excavated. The mouth of Sanbai Canal was abandoned, and the mouth of Lifeng Canal was re-excavated. Now the mouth of Guanghui Canal is abandoned again. What can be done about it? !”

Zhang Shun couldn't help but feel sad when he heard this. For thousands of years, the Jingshui River has continued to flow downward.

In order to irrigate farmland, people in the five provinces of Guanzhong have dug all the way upstream along the Jingshui River.

This kind of spirit of man's victory over nature is really touching.

After walking for several miles, everyone saw another aqueduct mouth.

"This is the head of Guanghui Canal!" This time Zhang Jinyan finally confirmed Zhang Shun's guess.

The channel was only two meters wide and was almost inconspicuous to Zhang Shun.

Even compared with the water diversion entrance of Zhengguo Canal thousands of years ago, it is much narrower.

Zhang Shun silently took a closer look and saw that the canal was plain and plain, except that both sides of the canal were covered with stone walls that were washed away by the river water and became extremely shiny.

If you don't analyze it carefully, the water in this canal seems to be embedded in the rocky mountain.

"Going down from here, there are two caves at Dalong Mountain and Xiaolong Mountain." Zhang Jinyan couldn't help but explain.

"Because the rocks in the mountain are as stubborn as iron, the work is very difficult. The people of the five counties used charcoal moxibustion and vinegar to quench it every day, and then chiseled it, so it was named Iron Cave!"

Zhang Shun reached out and touched the black and white rocks on the bank of the canal, and couldn't help frowning. No wonder this place is called "the rocks are as stubborn as iron".

According to his previous work experience, this is a very hard sedimentary rock that would have required explosives in his previous life.

However, in this era there was only black powder, and there was no good way to get this hard rock.

The method of thermal expansion and contraction like "charcoal moxibustion and vinegar quenching" mentioned by Zhang Jinyan is already the best way to dig.

Shaking his head, Zhang Shun walked to the bank of Jingshui River again. Looking at the more turbulent river water and the mouth of the canal that was almost flush with the river surface, he couldn't help turning his head and asked: "Zhixian Zhang, do you think it's below the mouth of the canal?" What if we build a dam in the river to store it as a reservoir and use iron gates to open and close it?"

This was the best way Zhang Shun could think of. Although there was no cement in this era, if stones were piled up to form a gravity dam, the water level was raised, and a reservoir was formed, then Jingshui could be introduced into the Guanghui Canal.

Zhang Jinyan shook his head when he heard this and said two words: "silt sand!"

Perhaps Zhang Jinyan did not understand what a "dam" was, but this did not prevent him from inferring the results of such damming and impounding water based on his many years of experience.

Zhang Shun looked down at the turbid Jingshui and then reacted.

Not to mention that the Jingshui River flows so fast, even if the dam is built, the huge sand content alone will be enough to silt up the reservoir.
