The spring of the fourth year of Kaiyuan, Daqin.

The emperor drew several lines on the map, so the whole world began to get busy around these lines.

The first line was to re-drag the Grand Canal from the North and South. The court established four canal transport envoys, responsible for the Hebei section, Henan section, Huainan section and Jiangnan section of the canal. The four transfer envoys all had their own transfer envoys, who were responsible for the dredging of the canal, taxes on the Heguan Pass, maintenance of dams, and safety of canal transport.

The second line drawn by the emperor was to rebuild the Qin Straight Road from north of Chang'an, Guanzhong. At that time, Qin Shihuang ordered a road from Yunyang to Wuyuan County, Hetao, which was more than 700 kilometers long.

This road is still in use at this time, but many places have been disrepaired for a long time.

The key to the emperor's second line was that the Qin Dynasty had now recovered the Hetao territory. The Yellow River has many harms, and the only one is rich. Hetao is a granary that is blocked. If you want to defend the northern border well, this granary is extremely important to the Qin Dynasty.

But although Hetao is rich, it also has a very fatal problem, that is, there is a huge desert Gobi between Guanzhong, which is too big and difficult to pass through.

If you do not directly cross the Hengshan Mountain and the northern desert from the north from the middle of the north, you can only go north along the east bank of the Yellow River, or go north along the east bank of the Yellow River. However, there is one problem with these two routes, one is to take a longer road, and the other is to walk along the Yellow River. Especially the route to the east, it will face countless rivers and valleys that go east and west. With this ability at that time, it was difficult to continuously cross these rivers and build a straight road.

If you have to constantly bypass these rivers, the road will be extended infinitely.

It is precisely for this reason that Qin Huangshi finally ordered a straight road to go north and reach Wuyuan.

To cross the Hengshan Mountains, to cross the vast desert, especially to go directly north, you also have to face the problem of crossing many valleys and rivers. At that time, the Qin people came up with a wonderful idea, that is, to build this road on the watershed of Ziwu Ridge.

If you build a road along the ridge, you can run ten carriages in parallel.

Ziwu Ridge is not low, but it is not very high either. It is a height that can be built and walk on the road. At the same time, the climate and terrain of Guanzhong make it relatively simple to build roads on the mountains.

The most important point is that in this way, the road construction perfectly bypasses the valleys on both sides of the Ziwu Ridge ridge, and there is no need to fill the mountain and build a river, and directly passes through the ridge.

He arrived at the south side of Dingbian County, Shuofang, and then entered the Ordos Plateau northward. From then on, he crossed the Yellow River at Zhaojun Tomb and arrived in the Baotou area of ​​later generations.

This route greatly reduces the distance from Guanzhong to Wuyuan, especially the route from Yunyang to Shuofang Dingbian, which are all continuous mountains and countless valleys. It can be said that this route is simply a miracle.

The 1,500-mile straight road, which is an average width of ten feet, not only avoids the valleys and rivers, but also is built on the ridge of the watershed, so it is not far away from the water source. This is extremely important for military marching and material transportation.

It was not until recent years that a Yellow River Highway along the Yellow River Grand Canyon in Shanxi and Shaanxi was built. It can be seen that there are too many straight roads in Qin.

However, after Qin, his mastery of Hetao was not firm, so this straight road did not achieve the purpose of Qin Shihuang's original design.

This road design is an offensive path, connecting Guanzhong and Hetao.

However, after Qin, in order to prevent the Hu people from going south directly along this road, the court adopted a conservative defensive strategy against this straight road. When they contacted Hetao, they used Yunzhong County in Daibei to control Hetao based on Yunzhong in Yanmen, Taiyuan. Or, in many cases, they used Yunzhong to restrain the Hu people who defended Hetao.

While restoring the Qin straight road, the emperor also drew a line, opened a waterway from Lingwu, and went straight to Yulin County, and built a water transportation line with the entire Hetao area, a section of the relatively gentle Yellow River Hetao, which was built.

Many areas of the Yellow River cannot be shipped, but the river surface of more than a thousand miles in the Hetao area is suitable for navigation and can be shipped.

Therefore, the Qin straight road was repaired, and the land passage from Guanzhong to Jiuyuan City was opened, and the emperor also opened up the Yellow River shipping from Lingwu to Yulin.

After the shipping was opened, Guanzhong and Hetao were no longer tied with a thin thread.

At the same time, a Yellow River route can also closely connect Chang'an, Hexi, Longyou, Shuofang and Dingxiang.

The 1,500-mile straight road and the 1,500-mile waterway are completely opened and connected.

The third line drawn by the emperor was to go from Tongba County, Hanzhong, then to Qianzhong, connect to Yunnan, Guangnan, and connect to Jiannan.

This southwestern artery completely colludes with the entire southwestern region and revitalizes them together.

The emperor drew several lines, and the entire northwest and southwest regions became huge construction sites.

The shipyards that can be seen along the way are timber factories everywhere, dragging rivers and valleys, and following the emperor's route, they must connect these old roads along the way.

This is a major project, and almost all counties in the southwest, northwest and northwest were mobilized.

Every day, new ships enter the water, cars and horses gallop on the road, teams of slaves are sent over, and countless people respond to the government's call during the slack farming period, accept employment to build roads and make money.

All counties and counties implement comprehensive planning and then carry out the work in different parts and pieces.

When you open a road when you encounter mountains, build a bridge when you encounter water. Every ten miles is a dormitory, every twenty miles is a post station, a thirty miles is a military station, and a 50 miles is a military fort.

On this side, a team came along the Han-Qian Road, which had its original shape.

A young man in the team watched the people who built roads along the way no longer had the curiosity and excitement he had at the beginning. His name was Li Sanlang, also known as Li Sanbao, from Luling County, West Road, Jiangnan. He was a poor family, so he went into the shop to become a friend apprentice. The apprenticeship in this era was not as simple as that in later generations. He went into the shop to become a master. He didn't let you learn anything in the first three years, but just served as a quarrel.

In the words of the master, this will make you look at your character. It is not difficult to learn craftsmanship, but it is difficult to raise a population. If the apprentice is impatient and unable to bear it during these three years, you will be expelled and will not teach skills at all. Even after these three years, the master will not pass on the craftsmanship to you at once.

In the second three years, you only teach basic skills and serve the master at the same time. You can only get some simple things in the third three years. After the fourth three years, you can barely become a master, but you still have to continue to do things for the master in the shop. There is no random job change. Even the first ten years, the guy basically has no salary. It is good to have a stuttering. If you give something during the holidays, you will be generous.

If there were no such turmoil at the end of the Sui Dynasty, perhaps Li Sanbao would have been determined in his life, and he would have been able to survive for three years, from an apprentice to a client, then to a manager, and then to a shopkeeper. When he was old, he might have been able to save a small amount of money, and then return to his hometown to buy some land and enjoy his old age.

However, the world was turbulent. Last year, he followed his master north to Yuzhang County to do business, but he encountered a war between Lin Shihong and Shen Faxing. The master was killed and the goods were taken away. He jumped into the river and fled. Later, he swam to the north bank of the Yangtze River and became a wanderer.

Fortunately, he was lucky, and the north was unified and relatively stable at this time.

Although the Three Feudals in the south are in the prime of Qin and the north do not fight south, the Three Feudals themselves still attack each other continuously.
