"So you're riding this section, so you won't be afraid. Take me nearby and see the ruins of the Great Wall. Is this the starting point of the Qin Great Wall?"

Li Su: "That's not the case. The starting point is Lintao, and this is Didao. It is already the second stop. The starting point is a distance from a county south. You want..."

Liu Miao immediately stopped it sensibly: "No, I will ask casually. I am not a foolish woman who admires the brave and brave men. As long as you have seen the Great Wall, it will be the same in any section."

Liu Miao knew very well that Li Su's entourage was at least 500 elite iron armored soldiers. If these people were allowed to go back to another county, they would walk back and walk over just to see the Great Wall, which would be too coquettish and willful.

What's more, Liu Miao himself doesn't like to be exposed in the wind and sand for a long time, and maybe he will get tired of walking twenty miles.

Looking at the mountain, they saw the ruins of the Great Wall on the ridge from afar. When they really climbed to the top of the mountain, they had already walked over twenty miles of slopes. Li Su also specially chose a wall that looked better preserved, took Liu Miao and Zhou Ying over, went nearby to observe carefully, and took a group photo to check in.

After watching for a while, Liu Miao felt a bright and comfortable mood. She proudly held the whip and pointed at the Tao River from a distance: "This mountain is not difficult to climb, so you can easily get up by riding a horse."

Li Su smiled proudly: "I have seen the secret letter sent by Yunchang. This road did not exist last year. There were only gentle slopes in the mountains and rugged slopes trampled by people and horses.

Last year, taking advantage of the slack farming period, Xu Shu, the magistrate of Jincheng County, distributed some manpower from Didao's corvee workers. He originally planned to send him to Liujiaxia, Jincheng to build a dam, but he stayed in Didao's local area and slightly repaired the road that crossed Baishi Mountain to achieve the level now."

It turned out that this road was just built by Xu Shu. Although it was still a loess road, it was at least two meters wide, and it was easier to walk on the road.

The farming of Liu Bei's camp is really not vague at all.

The place name "Didao" has been named since ancient times because it is the junction of the Wei River Plain where the old Qin people lived and Rongdi in the western Tao River Basin. There is a valley mouth on the mountain to cross. Even the Great Wall was built along this mountain, which proves that the west side of the mountain was the Rongdi land in the pre-Qin period, and the east side of the Shandong was the land of China.

Since Li Su will combine Guanzhong and Xiliang more closely in the future, it is definitely very important to open up land communication between the main rivers of the two places. From then on, Taoxi can no longer be considered as Rongdi's territory, but it must be from China!

There is only a straight line distance of 80 miles between the two major water systems, plus this rather towering ridge, and there is an abandoned Great Wall level at the highest point of the valley. Of course, such a place requires capital to completely level the road.

The group was filled with emotion, especially those girls who felt the magnificent mountains and rivers, and were fascinated for a long time. The road down the mountain was easier than going up the mountain, and they walked faster and faster. After walking more than ten miles, Li Su saw a mound of soil similar to a small pyramid not far from the mountain road. She was a little surprised and had a bad premonition.

Liu Miao had never seen such a thing before, so he couldn't help asking: "What is this? Such a desolate place and such a grand creation."

Li Su thought about it: "This looks like Jingguan, but it does not insult the dead like Jingguan. It seems to be just a mass grave with insufficient conditions."

Liu Miao and Zhou Ying both shrank slightly back: "So big, are dead people buried?"

Li Su hurriedly comforted: "It won't be many, look at the size of this, at most hundreds of people. After all, it's not a pile of heads, it's all buried, so don't be afraid."

After comforting him, he also went over and took a closer look. There was a wooden monument and a wooden square pavilion beside the road. After looking at the words on it, he found out the whole story.

It turned out that it was all the Qiang people in Taoxi and Song Jian who had evaporated by Xu Shu, and Han Sui's army captured the dead who had been repaired by Shulu. It took several months to build the mountain road from Weiyuan to Didao, and more than 200 prisoners died.

In ancient infrastructure projects, it was inevitable that people would die. After all, even in the 20th century, construction sites were full of dangerous jobs. Entering the 21st century, human lives were valuable and safety production measures were further optimized, which basically eliminated the phenomenon of death on real estate construction sites.

The woman in the boudoir didn't know the cruelty outside. When she saw that so many people were going to die in the repair of the corvee work, she couldn't help but look pale.

Li Su comforted: "If you think so, it has been four hundred years since the Han Dynasty. More than 200 people died in the construction of the Didao Mountain Road. More than 400 years ago, when Qin Shihuang built the Great Wall here, he had not yet reached the mountain. How tragic should it be?

Maybe it will double again? triple? Five hundred dead in the Great Wall of a county, and more than ten counties along the Great Wall, with more than 100 counties and more than 100 counties along the Great Wall, with a total of more than 50,000 or 60,000 dead. I believe that Yuan Zhi was a person who cherished his life, and even if he was a prisoner of rebels, he would not sacrifice his life on purpose. The predecessors planted trees and later generations took advantage of the shade. Now we are doing a solid job, and later generations will assimilate the Western Regions, and the losses will be even smaller."

Liu Miao, Zhou Ying and others were silent when they heard this, and they didn't speak much on the way down the mountain, all the way to Didao County. Everyone stayed in the county for another night, and then they all got on the caravan the next day. After leaving the city, they drove the convoy into the Tao River and went down the river.

It was the first time that Liu Miao saw the caravan's use of both land and land. She was so excited that she felt that her travels around the world this time was too romantic and fantastic. Although she had never watched westerns and did not know what the atmosphere of westerns should be, this did not hinder her aesthetic.

In mid-February, there were already farmland and pastures on both sides of the valley, which were green and green. Some of the fields were used to plant cotton. They had never seen the stems of cotton before, and they felt more and more like they were in a fairy tale.

On February 12th, the caravan convoy drifted on water for another day and a half, and finally entered the Yellow River and arrived at Liujiaxia dozens of miles upstream of Lanzhou City.

It was Liu Miao's first time here, and he didn't feel anything. Li Su and Zhou Ying came last year and saw that the water near Liujia Gorge became more spacious and broad, with green water, and I couldn't help but feel a little scared of deep water.

Li Su was also afraid that the caravan's wave resistance could not be adapted to places that were tens of meters deep, so he could only adapt to the shallow river, so he ordered the convoy to drive along the shore. When he found that the water flow had become turbulent, he immediately went ashore and let the horses scattered on the shore pull the cart forward.

Liu Miao noticed Li Su's expression and asked curiously: "Is this place different from last year?"

Li Su nodded: "I really didn't expect that Yuan Zhi and Yun Chang had fought so quickly. I don't know how many prisoners of Han Sui and Song Jianjun used to build atonement day and night.

The water surface here is so wide, obviously an additional water storage area is dug next to it, which facilitates the storage of water in the Yellow River during the flood season and releases water in the dry season. It also mediates the flow of Tao River into the Yellow River, ensuring that the speed and impulse of the river bank downstream is always stable and the irrigation can be stable."

The girls didn't understand the reason, so they just asked blankly: "This water conservancy can benefit many people, right?"

Li Su smiled comfortably: "It's hard to say the specific numbers at the moment, but I definitely want to ask Yuan Zhi for me. Let's go downstream and take a look."

The convoy went down the bank of the Yellow River for several miles and soon saw a newly established market town at the entrance of Liujia Gorge. The people suddenly lived in it, at least from the perspective of population, which was already very prosperous. Moreover, the nearby area was far from complete, and the downstream was still a bustling construction site.

After discovering Li Su's convoy, the patrol and scout troops on the construction site came to investigate, but soon they did not dare to be arrogant, but instead informed the local responsible officials.

After a while, Xu Shu hurriedly brought a few followers, looking as if he was diligent in water control with "no hair, no hair grows in his hair" and came to greet the superior in person.

"The right general came to Lanzhou again to inspect, and the whole county was full of excitement." Xu Shu said from the bottom of his heart.

Li Su got off the car and got on the horse, walked with Xu Shu, patted him on the shoulder: "We are all serving the king and governing the people for the court, why should we be restrained? I brought Lingtai Zhuge Liang this time, but he brought a lot of good things to you Lanzhou, all of which are for the benefit of the people of Xiliang."

(I also know that the second update today is too shameless, and I actually had a love scene for a chapter. I was ready to be jumped to watch, so I quickly redeem my sins in the third update and took me back to farming.
Chapter completed!
