The biggest change factor in the geography of China from ancient times to the present is following the Yellow River. In the early days, the estuary of the Yellow River was north of the Shandong Peninsula. At this time, due to the Yellow River taking the Huai River in the Song Dynasty, the downstream was diverted, and it was merged into one with the Huai River. The estuary was directly changed to the south of the Shandong Peninsula.

Zongjia Avenue heads south from Liaoyang, and after passing Shandong, this area is located along the canal. It exists as another major artery that communicates north and south in the eastern part of China outside the canal.

Zongyi Avenue also passes through the capital, but the starting point at its northern end is Guangwufu, the capital of Mudongzhou, the grassland in the south of the desert. Guangwufu was originally Guangwu Town, an important town gathering in the northern part of the former Tatar Korqin Duoyan tribe, and is now the capital of Mudongzhou.

Starting from Guangwu, it runs straight south through the eastern grassland, passes through the Great Wall Pass, enters Miyun, and meets Longjia Avenue in the capital, then goes southwest, passes Baoding and goes south along Taihang Road to enter Henan Province, and meets Hengyi Avenue in Yangwu. Then, like Hengyi Avenue, continues from Kaifeng on the opposite bank of the Yellow River, Hengyi goes west to Luoyang, Guanzhong, and Zongyi continues to go south, passes Nanyang, and enters Hanyang, which borders the Yangtze River in Huguang, as a middle third. Later, it meets Jiangxia on the opposite bank of Hanyang and Hengbing Avenue, and looks south to connect to eastern part of Huguang and western Jiangxi, and finally to Panyu in Guangdong.

The last main road in Longbing Bing, the starting point of the northern end is the capital of Muzhong Prefecture. Juyan Prefecture was named after Yanhai. It was named Yijinai during the Tatar period. After Muzhong Prefecture was established, it was used as the capital of the prefecture and changed its name to Juyan Prefecture. Hengjia Avenue also passed by and met with it.

The Bing Avenue starts from Juyan Prefecture, goes south to the grassland, runs through mountains, Shaanxi, crosses the Yellow River, and meets Hengyi Avenue here. Then passes through Hanzhong and enters Sichuan, passes through Yunnan and Guizhou, and finally ends at Jianshui, Lin'an Prefecture, Yunnan.

Three vertical and three horizontal roads connect the east and west, connect the north and south, and form the main veins of the road traffic system of the Daxia Empire. The shortest one of the six avenues is more than 6,000 miles, and the longest one exceeds ten thousand miles, with a total mileage of 60,000 miles.

I'm afraid no one has ever thought about this huge national project in all dynasties before this. Perhaps some people have thought about it, but the productivity level does not meet the requirements, so they can only go around in their minds and let it go, which cannot be achieved at all.

But Ying Yi dared.

The main trunk of sixty thousand miles, three horizontal and three vertical, must be built within one year, even in the era of hundreds of years, it is mostly delusional. But Ying Yi has a certain confidence - one is tens of millions of slaves available, two is not short of food, and three is the Yuanqi scheme to provide convenience.

It is precisely because of these conditions that Ying Yi has a bolder follow-up plan - the construction of secondary and final roads.

The so-called secondary road is a road connecting county governments, which can be called official roads in the past. The nodes are county, prefecture and prefecture-level capitals. In the large framework built by the main roads, a road traffic network connecting counties, prefectures and prefectures in the south and north of the sea during the summer.

The mileage of secondary roads is even more terrifying than that of main roads. However, secondary roads have their foundations - the official roads established in previous dynasties are the foundations. On the basis of the official roads, they are improved and rested.

Finally, the last level road is actually the connection between villages and villages. The ultimate goal of road traffic is to achieve barrier-free communication between villages and towns. Just like the country before Ying Yi traveled through hundreds of years later.

Tens of millions and the continuous growth of slave labor is one of the foundations for establishing this magnificent transportation system. High-yield grain in two seasons a year is another foundation, and the third foundation is the Daxia government agency that is united in the top and bottom.

The Ministry of Works, which is in charge of transportation construction, has already come up with a general strategy and has been recognized by Ying Yi. This strategy was officially improved and promulgated in the spring of the second year of the Chinese New Year.

The specific strategy is to divide the road system according to the prefecture and county level. Then contract it to merchants willing to contract. The imperial official only needs supervision, and then take out a sum of money and a batch of grain.

The contractor does not need to recruit many workers, and the slave camp is the main force. The contractors are actually just a factor in sharing the official chores of the empire and saving the government a certain amount of energy. And they can get a lot of profits from it - road contractors do not have part of the use of the road, they will only get the money that the empire has taken out - anyway, the empire needs to prepare a large amount of money and issue new coins at the beginning, which is also a way to issue.

According to the division of the prefecture and county level, a large number of merchants can afford it based on the complexity of the project volume. If divided according to the division of the project volume at the state level or even larger, there may not be many construction projects.

In fact, this is also a macro strategy for the empire to mobilize the circulation of human, material and financial resources of the people, and through this strategy, it accelerates the popularization of new coins and promotes the circulation of commercial goods. Therefore, this strategy, Ying Yi's outline and the Ministry of Commerce participated in the improvement.

Once the road traffic system is built, it does not need to be fully built. As long as the main road is built, its significance to this new empire is foreseeable. Whether it is civil exchanges, commercial circulation, or military purposes, it is incalculable.

The cattle and sheep on the northern grasslands can pass through the three main roads of the Longan and use corpus transport vehicles that will be gradually used for civil use in the future, and can reach the southernmost end of the empire within one day. The medicinal materials produced in Liaodong can reach the westernmost end of the empire through the three main roads of the Hengan and within one day.

Wars occurred on the frontier, whether it was the dispatch of materials or the mobilization of the army, they could reach a certain position before the situation deteriorated and changed.

The strategic significance is unparalleled.

Therefore, even if half of the millions of slaves die or even all die, Ying Yi will build this system.

Of course, this is impossible. If the productivity of the previous dynasty wanted to build such a system, ten million people would probably die. Grasslands, deserts, plateaus, and mountains were all huge obstacles to building roads.

However, the Yuanqi plan can provide guarantees for this.

The newly released deduction function, on the day of the founding of the country, Ying Yi spent tens of millions of humanitarian energy to deduce three plans. One of them was about road construction.

He needs a kind of ingredient, a kind of ingot that can efficiently drill mountains and build roads.

This plan was perfectly formed in the spring of the second year of the Huaxia Ji after nearly half a year of deduction. At present, Yuanqi Palace is in the process of the plan.

This new element is fully in line with Ying Yi's purpose in the deduced plan. It has two efficient functions: one is to dig a mountain and the other is to build roads.

There is no need to say that you can dig a mountain. For example, you can enter Sichuan and Sichuan, go west to the Tibetan plateau, the grasslands and deserts in northern deserts, and the poor mountains and rivers are endless. According to the old ideas, you can fill it with gunpowder, hammers, and chisels. With this kind of ingredient, you can easily open the mountain.
