Chen Zhengtai quickly returned.

Back to the carriage, sat obediently in the corner of the carriage.

Zhang Qianze poured tea for Chen Zhengtai unwillingly.

Chen Zhengtai smiled and took the tea handed over by Zhang Qian, took a sip of the tea, and then said to Li Shimin: "Your Majesty, you have already known this route, forty-hundred miles. The reason why I used wooden tracks was because wooden tracks were easier to lay, and as long as I was willing to spend money, the progress of the project would not be slow."

Chen Zhengtai immediately said as he knew it: "Of course, this is just the early stage. First, the roadbed and wooden tracks are laid out. After that, the wooden tracks can be wrapped in iron, and even replaced directly with railway tracks in the future..."

Li Shimin and Zhang Qian were both dumbfounded and sighed deeply in their hearts, railway tracks are crazy, steel is still very scarce in this era. At some point, if it is because of the lack of copper, the iron can even be directly cast into iron coins and laying a railway track of thousands of miles. Isn’t this equivalent to laying the money on the ground and almost turning around the Tang Dynasty?

I'm afraid the cost is more than thirty times that of the current wooden track.

It's so scary that the wooden track has already spread the money like paper.

Chen Zhengtai also needs to lay the railway tracks.

But from Chen Zhengtai's tone, it seems... it is like laying wooden tracks and saving money.

Li Shimin stared at Chen Zhengtai in surprise.

Chen Zhengtai didn't care what Li Shimin thought, but continued: "There are disadvantages of this wooden track, which is that it must be maintained carefully. However... as long as it is thoroughly integrated in the future, there will inevitably be countless cars and horses along the way. As long as there are people driving, there are no need to worry too much. The maintenance cost can be earned through various stations in the future."

As he was talking, the carriage moved.

The huge carriage made a creaking sound on the wooden tracks, which was quite shocking.

The carriage was pulled by two horses. After a brief vibration, then... Li Shimin's eyes turned and saw countless scenery outside the crystal window starting to move backwards.

It is obvious that there is soft packaging inside the carriage, so although there is noise, it is still in a controllable range.

Li Shimin couldn't help but stand up, and when he arrived outside the crystal window, Zhang Qian's embarrassing voice came from behind: "It's so scary."

It's indeed a bit scary, and it runs a little hard.

After two strong horses pulled the carriage, the carriage seemed to run wildly along the huge inertia.

This speed... is much faster than Li Shimin imagined. You should know... this carriage should be very heavy. After all, the carriage is quite large and there are furnishings inside.

But under the drive of the rolling bearing, once the car is pulled, the wheels rotate wildly. Because the wheels fit with the wooden rails at the lower end, there is almost no friction, and the car looks like a wild horse without any obstacles.

Li Shimin was surprised to find that... the cars in front and behind... were also running all the way. Some of these cars and horses were loaded with a large number of guards, while others were loaded with a lot of luggage, but their speed was also amazing.

Of course, this speed is nothing to Chen Zhengtai. Even the backward steam train in later generations was faster than this, but Li Shimin was quite shocked.

The carriages in front and behind are several times the load of ordinary carriages. What's terrible... but they can run at such a crazy speed, which... is not simple.

Li Shimin was shocked, and he became interested and asked with a serious look on his face.

"How much can this car travel per day?"

Chen Zhengtai said in a casual manner: "Every hundred miles away, there will be a special station to provide horse replacement and supplies. If you keep changing horses along the way and just keep changing horses, you can run for 300 miles in one day."

Three hundred miles...

Li Shimin's body was shocked.

In fact, if you are just a person, using the post station to convey messages along the official road, you can actually do this in the Tang Dynasty.

But if a group of people, coupled with the supplies of these people, can achieve a journey of 300 per day, it would be terrible.

Li Shimin was the one who led the troops. He knew that even if he was in a hurry, he could travel thirty miles a day and be considered an elite soldier.

In the vast grassland, the Turks could travel hundreds of miles a day because there were no obstacles. No matter how many, it was unheard of. After all... this is a large number of people and horses, which had to carry a large amount of horse materials, and people had to carry a lot of dry food. People had to rest and horses had to rest.

But when people were sitting in the car, they were obviously in a state of rest. This might be bumpy along the way, but the rider would not be so tired when he was driving the horse.

As for changing horses along the way and setting up stations, this is nothing. After all, the most common ones in the grassland are horses.

Traveling three hundred a day is like Kunpeng in "Zhuangzi, Xiaoyaoyou".

Li Shimin's interest grew.

At first, he could feel the horse trying to pull the carriage, and later, he felt that the carriage was just running along the wooden tracks.

He couldn't help but murmur: "Travel three hundred miles a day, and walk three hundred miles a day..."

Zhang Qian, who was beside him, couldn't help but change his face suddenly, looking in disbelief.

I couldn't help but admire Chen Zhengtai, it was amazing.

Chen Zhengtai sat aside, but looked very calm.

He even thought to himself that if you travel three hundred a day, you will still be...

Thinking back to the time when my magic car Wuling Hongguang kicked the accelerator and I could run 3,000 miles in twenty-four hours a day. That’s it… I still have to sleep and get off the car and eat and drink in the middle of the way.

But for this era, this is almost a miracle.

If it weren't for personal experience, Li Shimin would never believe it. He even felt that Chen Zhengtai was talking big.

At this moment, Li Shimin experienced it personally, and the scenery along the road moved back wildly. He was sure that Chen Zhengtai's words were not false, and he was immediately excited.

Because the carriage was running fast, it was not until about 150 miles before it stopped. It seemed that it had arrived at a stop. Li Shimin got off the car, and the people at the station began to replace the horses. Suddenly, Li Shimin had discovered that he would arrive at the grassland soon.

This Guanzhong is not far from the grassland, and the wooden track uses a straight road, and you can practice it straightly without too many twists and turns.

The long list of cars and horses behind him also stopped steadily, and the guards in the car got off and rested. The guards did not seem to have expected that the journey was so smooth, so they got off with great enthusiasm. The process of changing horses was very short, because the people in the station obviously had experience. They were well-trained and in a moment, someone notified everyone to board the bus.

Li Shimin even took a nap in the carriage. When he woke up, he found that he had arrived on the grassland. Outside the window, there were lush green grass, rising and falling under the strong wind, like a green ocean...

The grassland at this time cannot actually be called the desert in later generations. Because of the abundant rain in the Tang Dynasty, the grass grew very vigorously. In the distance... some scattered cattle and sheep were seen, and I don’t know whether it was wild animals or the shepherds lost it.

Li Shimin could even see that occasionally, there were some people patrolling the road next to the wooden track, riding horses, leisurely and leisurely, and some even seemed to be driving their own cattle and sheep.

Look at their appearance, they are dressed as Han people, in groups of three or three.

Chen Zhengtai saw Li Shimin's curiosity and explained with a smile.

"The pastures were established near every station. In addition to raising cattle and sheep, the people on this pasture also took on some warning and defense. Naturally... the rails were long, so it was impossible for them to do these things in full. They just wanted them to ensure that there would be no horse thieves and sluts nearby. The Chen family even had seventeen pastures along the way, and there would be more in the future. Most of the pastors were Han people, recruited from Guanzhong."

Li Shimin felt more and more surprised, his eyes were full of confusion, and he looked at Chen Zhengtai.

"Han people shed horses?"

Chen Zhengtai nodded and then smiled.

"Your Majesty, it is of course difficult for the Han people to shed horses, but before, they only heard that Hu people could shed horses because the Hu people had no other livelihoods. To be honest, who would like to eat and drink dew in this grassland? But now, the Chen family has set a purchase price for the cattle and horses on the pastures to ensure that their cattle and horses can be exchanged for money at any time after they grow up. In addition, some merchants gathered around Shuofang and the railway. Because the shepherds have money, they are willing to sell fruits and vegetables transported from Guanzhong in the market. With this wooden track in the future, the transportation of goods will be much more convenient. For the shepherds, shepherds are just a profession, and their daily food, clothing, housing and transportation are actually not worse than Guanzhong. The Han people are also people, and there is no difference between them and Hu people. They can shed horses, so why can't the Han people? The main thing is to see how to protect their livelihoods and interests, so they are naturally willing to do it enthusiastically."

Chen Zhengtai paused: "The cattle and horses on the pasture here will be transported to Shuofang or Guanzhong. In the future, it can be supplemented with Guanzhong's livestock and can also provide a large amount of fur and meat to communicate with each other. In fact, what the Central Plains have always lacked is livestock and meat. However, this grassland is occupied by the Hu people, so cattle and sheep and horses are monopolized by them. The trading volume of the imperial court is not high. If a large number of cattle, sheep and fur can be poured in, it will be a good thing for the grassland and the Central Plains."

Li Shimin nodded, but he was still quite worried about the Han people's horse shedding.

But at this moment, he felt a little more anticipated about Shuofang.

……………………

"Khan." Someone hurried into Tuli Khan's tent.

Although Tuli Khan was a minister to the Tang Dynasty and was named King Guiyi, in fact, on the grassland, he still called himself the Great Khan and commanded the Eastern Turkic tribes.

But... because of the inner affiliation of Tuli Khan, in fact, the various Hu tribes that were controlled by the Eastern Turks were actually divided into pieces. Tuli Khan used the support given by the Tang Dynasty to barely control the troops of the Eastern Turks.

Tuli Khan has been restless these days.

More and more Han people flocked to the grassland, which completely changed his mentality.

The original Tuli Khan even believed that he and the Tang Dynasty could coexist. As long as he received the support of the Tang Dynasty, he could reunify the grassland and become the co-lord on the grassland like his ancestor Qiming Khan.

It was just that the Han people entered the grassland, which meant that the Tang Dynasty was going to actually control these grasslands. At first, he was not worried, and even believed that these people who could not adapt to the grasslands were just a group of fat sheep.

But after these two years, he felt more and more that his wishful thinking had been completely wrong.

These Han people who flocked out of the customs quickly occupied the pastures, built pastures, built cities, and even tried to cultivate farming outside the city. The population of the Han people was already quite large. In the past two years, they not only gained a firm foothold, but also became more and more considerable.

What will happen if this continues? Tuli Khan cannot imagine.

He even smelled a trace of danger. Once the power of these Han people continued to expand, then... there would be no place for Turkic people in the world.

Although there were many conflicts, the conflict between him and the Han people began to deepen, but at this time, he still could not make up his mind.

After all, Tuli Khan knew very well that behind these Han people was the increasingly powerful Tang Dynasty. Once he decided to rebel, the Tang army and horses would quickly retaliate.

He was not even afraid of the Tang Dynasty, but he knew very well that the tribes on the grassland now had their own attacks. If they were hit by the Tang Dynasty, the Turkic tribes might be swallowed up by other Hu tribes that rose up.

Therefore, Tuli Khan could only endure it.

And at this time... a letter was sent.

Seeing the seal of the letter, Tuli Khan's face suddenly became solemn.

It seemed that Tuli Khan, with instinctive awe of the owner of the letter, rose up in awe and then took it apart.

After reading the letters roughly, Tuli Khan seemed a little unbelievable.

He murmured: "The Emperor of the Tang Dynasty actually entered the grassland. Not only that, even Ben Khan's 'brother' came. There were not many entourages around them."

Tuli Khan couldn't help but ask the others in the account: "Is there such news coming from other places?"

The Turks also have their own news channels in Chang'an. If there is any movement, there should be news.

The other generals shook their heads one after another, looking confused.

"Can this betray the Han people?"

"No." Tuli Khan shook his head and sighed: "This is Mr. Qingzhu's handwritten book, and there will be no falsehood. In this way, this matter is a very secret matter. Even in the Tang Dynasty, there will not be too many people who know these things."

"Mr. Qingzhu..."

Everyone was solemn.

Especially one or two people who know the inside story, someone couldn't help but ask: "What else was said in the letter?"

"He said...if the Emperor of the Tang Dynasty could be defeated, then the Turkic tribes could beg for the Tang Dynasty. Li Shimin was so arrogant that he dared to go deep into the desert alone, with the escorts he brought with him, and I knew that he was brave, but he could not see through this way."
