Pressing the waves in his heart, Bai Ya looked up at the road ahead. Although he has become alone again, he is no longer confused and at a loss, and he is determined to leave his own traces in this world.

The place where he is now located is the easternmost county of Wudu County, which is also the border between Qin and Han China.

A few days ago, when Bai Ya was walking with the old beggar, he asked him about some of the situation in Han China.

This place is hundreds of thousands of miles away from Didao City, where the mountains are undulating and endless, and belong to the Daba Mountain Group. The mountain range in front of him is the famous Dingjun Mountain in the previous life, and on the opposite side of the mountain is the county of Han China.

Han China was a small vassal state with only one county, which was Hanzhong County.

Hanzhong County is geographically subordinate to Yizhou, with the Qinling Mountains in the north and the Daba Mountains in the south, and the terrain is a basin, which is called the Hanzhong Basin.

Because there is the Qinling Mountains in the north as a barrier, the cold current cannot go south, and there is a water (i.e., Han water) running through the basin from east to west, the climate is warm and humid, the water is sufficient, suitable for the growth of crops, and it has been the land of fish and rice since ancient times.

Hanzhong has a long history, in the Western Zhou Dynasty, it was called Bao State, and the monarch was Bao.

The ancestors of the Bao family assisted Dayu to control the water, so he was enshrined in the country, and went through the Xia, Shang and Zhou dynasties. But what really made Bao Guo famous all over the world was a peerless beauty - Bao Xi. The famous "Princes of the Beacon Fire Opera" is talking about King Zhou You and this peerless beauty who doesn't like to laugh.

During the Spring and Autumn Period and the Warring States Period, Hanzhong changed hands several times between Qin and Shu. It was not until the annexation of Bashu by the Qin State that Hanzhong County was established here.

However, the Qin state also failed to occupy Hanzhong County for a long time, and during the prehistoric Shenzhou period, Shu and Hanzhong were independent. At that time, Ji Yang, a prince of the Zhou State, raised the banner in Hanzhong and established Han China with his retainers.

Although Han China was on the verge of destroying the country under the repeated attacks of Qin and Shu, it finally turned the danger into a disaster and enjoyed the national glory to this day.

Because Qin is strong and Shu is weak, if Qin annexes Shu again, Hanzhong will not be able to survive alone. And because the Hanzhong Prefecture belonged to Yizhou, Han China nominally declared itself a vassal to Shu and formed an alliance with it to jointly resist Qin.

Qin and Hanzhong did not have a talisman that could be directly transmitted, and the air route also came and went with the changes in the relationship between the two countries, so if you want to go from Fu County to Hanzhong County, there are only two ways left.

One is to take a boat ride with the help of the river channel of Chushui (i.e., Han Shui), and the other is to pass through the large post road that is intermittent between the mountains.

Bai Ya had been on a flower boat in Longxi County for more than ten days a few days ago, so this time he planned to see the famous big post road and the flying ferry that was said to be able to travel thousands of miles a day.

The post road site in Fu County is located thirty miles away on the outskirts of the city, called Feilindu, which is a place similar to a manor ranch.

There is a tall outer wall outside Feilindu, but compared to the well-guarded teleportation talisman array, there are not many soldiers guarding here, only a few officials and strong squads to maintain order.

The flying buses that take the Great Post Road have both scattered passengers and caravans carrying a large number of goods. The entrance of the two is different, and the entrance for passengers is to the south of Feilindu, so you only need to show the road guide. The procedures for the caravan are much more complicated, and the goods carried have to be checked again.

Bai Ya slowly moved forward along the queue, and when it was his turn, the official on duty only checked the bronze medal of "Shang Zhi" given to him by the old beggar, and was allowed to leave after paying five cents of silver.

Entering the outer wall, Bai Ya saw that the field inside was extremely empty. Except for the row of pavilions at the front, the entire Feilindu is like a meadow for running horses, with a lush green patch of green, and nothing like a horse-drawn carriage.

All passengers entering Feilindu will walk directly to the hotel pavilion after entering the door. Although these pavilions are all entering and exiting on one side, the two sides are not the same batch, as if the people who entered before have "disappeared".

However, Bai Ya was not surprised by this, although it was his first time to take the flying ferry, he had also inquired about some situations before, so as not to make jokes.

Bai Ya followed the traveler team into one of the pavilions, only to see that the ground of this pavilion is a tunnel leading to the underground, and the flat stairs extend diagonally, looking down at least more than 100 meters deep.

Walking up the stairs to the end, a huge underground plaza appears in front of White Cliff.

The structure of the underground plaza is somewhat similar to that of the subway station in Baiya's previous life, with the dome and walls inlaid with fluorite for lighting, and some small shops on each side to provide food and travel goods.

The biggest difference from the subway station is the "tunnel" in the center of the square. The subway tunnel in the previous life of White Cliff was straight forward and paved with railroad tracks, while the "tunnel" here is more like a sloping cave leading to the ground, and only the beginning of the tunnel is exposed in the square.

The cavernous tunnel is in the shape of a drum, with a diameter of almost more than 50 meters. On the inside of the tunnel exposed to the ground of the square, Bai Ya saw dense silver runes, which were carved into almost the entire inner wall of the tunnel.

There was a well-known flying car parked at the mouth of the tunnel, and because of the downward slope of the tunnel, White Cliff only saw part of it, but it was already very surprising to him.

This thing actually has nothing to do with the "car" at all, and its appearance is almost a "giant centipede".

If the connected flat carriages still have a bit of train smell, then the arthrops on the outside of the carriage that are like centipede feet are a little creepy.

Each carriage of the ferry, or centipede car, is about 20 meters wide and more than 20 meters long, like a cube, and the knobs on both sides of the carriage are seven or eight meters long, and the overall width is about 356 meters, which can be fully accommodated by the tunnel.

It's just that Bai Ya is quite curious, how is this "centipede car" going forward? It can't be like a real centipede, crawling in the tunnel with the arthropods outside the carriage, right?

In that case, Bai Ya felt that it was too infiltrating, and it was hard to imagine that the speed could reach the level of traveling thousands of miles a day.

With such doubts in mind, he quickly got into the car.

The interior of the carriage of the shuttle bus is quite comfortable, and it is generally divided into small independent rooms. Inside, there are tables, chairs and benches, as well as tea and pastries. In addition, there are crystal windows that resemble subway trains, allowing you to see what is going on in the tunnel.

"Is this a centipede version of the wooden ox and flowing horse?" Bai Ya was a little crying and laughing, but he did admire the imagination of the ancients in this world.

In fact, he had heard that when the Great Post Road was just emerging, it was not an underground post road, but was built on the ground, similar to the Great Wall of the Nations.

The ancients used the city wall built by huge stones to build post roads on the ground, and set up post forts every other way.

It's just that at that time, it was still in the early stage of the great fission of heaven and earth, and the Shenzhou region was not as vast as it is now, and the barbarian beasts and demons and monsters were not as powerful as they are now, and the post road on the ground was feasible.

With the deepening of the great fission of heaven and earth, after reaching the middle and late stages, the post road on the ground could not hold on.

The territory of Shenzhou has become too wide, and the post roads on the ground are getting longer and longer, and there are more and more dangers along the way. Even if humans later domesticated some brute beasts, there were still not so many manpower to guard along the way.

But if it is not guarded, the post road on the ground will be hit by brute beasts and demons and monsters, and it will have no value at all.

So, the wise ancients turned the above-ground post road into an underground post road, which means "Lao Tzu can't be provoked, can't you still hide?" The above-ground post road is not feasible, then I will build it underground, and there is a kind of you crawling in to attack!"

This measure has really made the Great Post Road extremely safe again, and it has truly become the main artery connecting people in Shenzhou.

Even with the safer and faster teleportation array and airways today, the cargo function of the Great Post Road is still irreplaceable. The consumption of the teleportation array is too large, the air route is limited, and only the big post road can meet the freight flow in various places.

While thinking about it, Bai Ya only felt a shock on his body, and the centipede flying car finally started.

After the ferry car drove for a while, Bai Ya finally observed its operation mode through the crystal window, and was immediately amazed, and at the same time knew why the ferry was designed to be like a centipede.

It turns out that the environmental conditions of the underground post road are much more complicated than those on the ground, because some of the underground rock formations belong to the high-hardness rock formations, and some of the underground beasts are dangerous, so the underground tunnel built is not a straight line, but a twist and turn, and the line is like a roller coaster.

In order to ensure the safety of the ferry, this was designed as a centipede.

The limbs on both sides of the carriage are actually similar to probes, and they create a magnetic force with the silver runes engraved on the inner walls of the tunnel.

This not only prevents the ferry from hitting the inner wall of the tunnel while traveling, but also accelerates by magnetic force, allowing the ferry carrying huge weight to travel at high speed by inertia.

This design reminds Bai Ya of the maglev train that has not yet been popularized in the previous life, and this ugly flying car has reached this technological height, so how can Bai Ya not feel emotional.

Although the shuttle can travel thousands of miles a day, it still takes more than 10 days to travel from Fu County in Wudu County to Chu County in Hanzhong County.

Baiya had heard the old beggar say before, in fact, in the pre-Qin period, when the great fission of heaven and earth had not yet begun, Fu County and Chu County were a stone's throw away. The two county towns are only more than ten miles apart, almost separated by a mountain.

After the great fission of heaven and earth began, the distance became the end of the world. Today, the two cities are thousands of miles apart.

Despite this, judging from the boundless situation of China's territory, Fu County and Chu County are still dependent on each other and belong to "neighboring counties".

Ten days later, Bai Ya walked out of the underground post road in a daze.

After the novelty at the beginning, he finally realized the hardships of riding the flying ferry. Although this train is not bumpy, imagine living on a train for ten days in a row......

However, after Bai Ya breathed in the cold air from the outside world, he was still refreshed. Now that he has entered the territory of Hanzhong County, he can use the teleportation talisman array, and he no longer has to take the flying ferry.

The most important thing is that he can finally fulfill the last life of Monk Huikong!
