When he learned that this He's jade was actually a treasure carrying the mandate of heaven, Wang Xu was overjoyed and hurriedly went to the temple to ask the old ancestor.

Although Zijue is asleep, simple things like this will still be replied to by using the system's automatic reply.

Wang Xu inquired about these treasures, and after learning about the magic of He's bi, he wanted to find more treasures.

As a result, Zijue did not agree, but told him that although the treasure of destiny was good, it was just the icing on the cake. If he could really change his life against the sky, the Chu State would not be destroyed by the Huai State, and the Zhou family would not become the lord of Luoyi City.

Hearing this, Wang Xu dispelled the idea of looking for the treasure of destiny all over the world. However, although this idea was dispelled, he attached more importance to the treasures of He's Bi.

After the Huai State annexed the Western Chu State, it expanded its territory to Jiangzhou and Hanzhong. It already has a full border with the Qin State.

The roads in Hanzhong and Bashu are difficult to travel, the logistics and transportation are difficult, and the land of Hanzhong has just experienced a war, the people's livelihood is withering, and a large number of fertile fields have missed the cultivation period, although Huaiguo did not carry out massacres, but there are still many people who died in the war, and these places in Hanzhong and Jiangzhou need to recuperate.

Now it is not suitable to fight with Qin, so after occupying Hanzhong and Jiangzhou, Sun Bin ordered people to block all the checkpoints leading to Qin, and sent a large army to garrison them.

Next, Huaiguo needs to allocate materials to help Hanzhong and Jiangzhou recover their vitality, and at the same time provide relief to the victims. Because of the war, there was no longer enough food in Hanzhong at this time, and Huai was needed to support.

The road in Hanzhong is difficult, the Han water is turbulent, the probability of the ship capsizing is very large, 100,000 stone grain and grass are transported to Hanzhong, at least seventy percent must be consumed, fortunately, the grain production in Huai has been very high, even because of the war, the grain has decreased, but the volume of Huai is large, even if the grain is enough to supply, the only problem is transportation.

Therefore, Huai returned to the road of building a gallop road.

If you want to firmly control Hanzhong, you need to build roads, and if you want to transport grain to Hanzhong, you also need to build roads, and even in the future, you need to build roads for the Qin State. Wang Xu soon agreed to conscript Minzhuang to build the road in Hanzhong.

Compared with the gallop roads built in other places, the gallop roads built in Hanzhong and Jiangzhou are extremely difficult. In this era, there was no gunpowder, no large construction machinery, and if you want to open mountains and split stones, you can only use fire. Burn the stone over a high fire for three days until it is red, and then pour cold water on it.

The difficulty and time required to excavate rocks and build roads in this way can be imagined.

After Wang Xu agreed, Huaiguo immediately dispatched a large number of materials and people to Hanzhong and Jiangzhou to build roads, and at the same time, there were many Yi tribes living in the mountains and forests of Hanzhong and Jiangzhou.

Some of these Yiren tribes were subject to the Western Chu State, some remained independent, and many were very hostile to the Western Chu and Huai States.

Now that we are preparing to build roads, these hidden dangers naturally have to be dealt with. Wang Xu's edict ordered Xu Fan to lead 5,000 Shanyue elite soldiers to clear these Yi people.

Those who are willing to accept the rule of Huai will be given preferential treatment, and those who are unwilling to accept will send a large army to conquest, with a big stick in one hand and sweet dates in the other, to conquest these Yi tribes.

Although most of these Yi tribes live in the mountains and forests, they do not need to communicate with the outside world. On the contrary, many things had to be traded with the outside world, such as iron, such as salt.

As long as you master these, win over some tribes who are willing to submit to Huai, and then let these tribes fight against tribes that are unwilling to submit to Huai. And Huai's Shanyue Jingshu was the last resort. This is also the experience gained by Huai's continuous southward expansion over the years.

As for sending a large army to conquest, it is a completely thankless task, which is a lesson that Huai and Chu learned back then. The mountains and forests are overgrown with grass and trees, among which there are many poisonous insects, snakes and ants, and there are many miasma, and it is easy for the army to conquer the water and soil, causing a large number of deaths and injuries.

The best way for Huai to send Shanyue elite soldiers to fight in small scale is to do so. In this way, the Huai were able to clear the barbarian tribes and trade slaves with the tribes who were willing to submit to the Huai State.

The population of the tribes who were unwilling to submit was plundered and then sent to the Huai kingdom to build roads. For the population, Huaiguo is not too much, and the construction of roads in Hanzhong and Jiangzhou requires a lot of manpower and material resources.

And the mountains are steep, and the casualties of road construction are high, so let these slaves come. At the same time, the Huai State did not want to force these slaves to death, as long as they worked here for a year, they could be granted farmland and become the households of the Huai State.

Huai requisitioned a large number of people to build roads, and at the same time, the construction of galloping roads in other places did not stop. Before the Huai State annexed Western Chu, the population was already 11 million, and now it has captured the Western Chu State, and the population is close to 13 million.

It is precisely because of such a large population that Huai can transfer so many people to build a gallop road.

The Huai State levied a large number of people to widen the road from Hanzhong to Xiangyang, which passed by the side of Shennongjia in later generations. In later generations, the Shennongjia area was all primeval forests, let alone this period.

Fortunately, the gallop is passed through the edge, otherwise it would have been more difficult to build.

The turbulent flow of the Han River, coupled with the mountains and rivers surrounding Yunyang, made it difficult for the Huaiguo Sailor to pass. In some places where it is difficult to sail, it is necessary to use a slender boat.

In addition to these, some difficult roads are built using plank roads.

The boardwalk involves making holes in the cliffs, then penetrating the hardwood, and then supporting the hardwood underneath it. Two pieces of wood and rock form a triangle, and then a layer of planks is laid on top. In this way, a path was carved out on the almost vertical cliff face.

Huaiguo opened up the gallop road in Hanzhong, and opened up the road that could only be parallel to two zhang into a plank road with a width of two zhang and parallel carriages, passing through hundreds of miles.

Below the plank road, it is not the cliff of the abyss, or the Taotao River, the difficulty of construction is extremely high, but after the construction is completed, the distance from Xiangyang to Hanzhong is shortened by one-third, and it is easier to pass.

However, because of the width of the plank road and the fact that it must be built along the mountain, it is too tortuous, so these plank roads cannot be laid with tracks, and the tram carriage cannot be passed.

In addition to the Hanzhong plank road, Huaiguo also made extensive use of plank roads on the road from Yicheng to Jiangzhou. At the same time, because of the turbulence of the Yangtze River and the large number of reefs in the water, a large number of slender men are also used here.

Through two ways, water transportation and plank roads, Jiangzhou and Hanzhong are connected with Huaiguo.

Because of the war, Hanzhong and Jiangzhou were short of food, and Huaiguo also adopted the method of work for relief to recruit a large number of people to dig plank roads and build roads, which not only accelerated the speed of building roads, but also allowed the people to gain benefits.

——

The ancient plank road of the Three Gorges and the ancient plank road of Hanzhong are a kind of passage formed by digging holes and building bridges and pavilions on the steep rock cliff in ancient China, and it is also the traffic artery of the soldiers attacking and defending, the project is arduous, the road is treacherous, it is unimaginable that more than 2,000 years ago, only the ancients of iron tools were able to dig out the plank road that is hundreds of miles on the cliff, and it has to be said that this is a miracle in human history.
