Datang first village

Li Yuanxing's Taoism is actually chemistry. . This thing is just a name, no one will take it to heart.That science is modern physics.Without these two kinds of knowledge, it would be difficult for Datang to develop.

Fortunately, Li Yuanxing was a student of these already outstanding talents.

Using the theoretical knowledge that already exists in modern times to become their own knowledge, if they start from scratch, it may be dozens of times slower.

Standing on the shoulders of giants, you will naturally be taller.

"Your Highness, the giant beast will be able to test the machine in ten days at most!" Ma Yuan's words made Li Yuanxing very happy.

In Yaozhou, in front of a rocky mountain, there are 300 guards alone.

When Cen Wen came here, he only knew that there was an important mission here, but he didn't know what it was for.

On the four steel rails is a huge circular steel beast that is five feet high and seven feet wide, like a long snake.This meeting is being assembled, and many parts are not suitable, so I have to go back and rework them.

The most original steam shield machine.

Ma Yuan ordered the two craftsmen to open the drawings and place them in front of Li Yuanxing.

"Your Highness, there are eight steam drills and four gravel conveyor belts in front of the road. The power to move forward has nothing to do with the wheels. The ground is used to grasp. Fortunately, the distance is only a few feet per day, so add power to the wheels. It feels like a waste. The only problem that is giving me a headache now is that the steam machine cannot exhaust after the depth exceeds one hundred feet."

Li Yuanxing looked at the drawings.

This shield machine does not use a huge disk as the open circuit of the modern superb.

Instead, a platform that can be raised and lowered is used. For a cave, it can be drilled one foot deep at a time. First, the drill bit with air pressure impacts from the top to break the stone, and the iron plate close to the stone wall below will slide the stone. to the conveyor belt and then to the back.

It can dig up to two feet at a time, and then the platform of the drill bit will descend to break the stones below.

It can be said that this is semi-artificial, semi-mechanical.

It would take Datang two years to produce that kind of cutting shield machine, and it doesn't have enough power.

Li Yuanxing planned to drive from Chang'an to Huazhou, which is the route chosen by the later Western Han Dynasty high-speed railway. The terrifying 130 kilometers, there are 120 kilometers long tunnels and bridges.

Li Yuanxing's Changcheng Railway has far more caves than later generations, but fewer bridges.

For Datang, digging holes was easier than building bridges.

Some routes have also been changed. Those who can walk from the side of the mountain only need to dig out a piece of the mountain.

But that’s it. According to Datang’s calculation of 270 miles, it can be said that all of them were dug out and bridged.The tallest tunnel is two kilometers long, and the shortest is thirty steps.Tunnels account for [-]% of the entire Changhan Railway, and there are several bridges that are impossible to avoid.

For the construction of this railway leading to Chengdu, the budget given by Li Yuanxing was as high as 700 million.The time is three years.

700 million guan, this number is about 300 billion in modern times.However, the proportion of more than 300 billion yuan in the total national output of later generations is very small.

Li Yuanxing's 700 million guan, for Datang, the total income of the household department in one year during the Wude period could not reach this figure.

In the early years of Zhenguan, not counting the Qin Palace, the entire Tang Dynasty only made 50 million coins.

Even now in the second year of Zhenguan, the annual income is only 800 million guan.

Li Yuanxing only needs to invest 700 million yuan in a railway, which scared a few old courtiers to a heart attack.

However, Cui Junsu believed that Li Yuanxing made a mistake.Because the consumption of manpower, material resources, food, and labor is far less than what Li Yuanxing said, he gave Li Er a seal, and the Ministry of Industry also put a seal, thinking that although the amount of earthwork on this railway is huge, it consumes money and food. The materials are no more than 300 million guns.

The reason is that all states and counties in Datang have the obligation to perform servitude.

Moreover, the food standard given by His Royal Highness King Qin is too high, each person, the food standard of [-] Wen per day, this is not road construction, this is a banquet.Even in the most bitter place on the frontier of the Tang Dynasty, the food standard does not have the principle of twenty cents a day per person.

Did Li Yuanxing make a mistake?

Li Er probably knew the reason.

Li Er remembered that Li Yuanxing mentioned to himself that it was extremely hard work to open the road in the Qinling Mountains.And it is very dangerous, so the wages paid are at least three times that of the section from Chang'an to Luoyang, and the food expenses are at least three times higher.Then there are expenses such as disability pensions, so Changcheng Railway consumes 800 million guan.

Li Er knew that Li Yuanxing had made a mistake, but he didn't remind Li Yuanxing.

Thinking back to the former Sui Dynasty, Yang Guang used millions of labor to build the canal, and then conquered Goguryeo three times. The labor labor who died on the road alone was said to be a million, but when the people received the labor order, they knew it was Death, but there is no way to avoid it, even if you bite the bullet, you will do it.

You, Li Yuan, built the Datang Stadium. Such a large amount of work would have taken at least two years in the former Sui Dynasty.

But your Prince Qin's mansion was repaired in three months.

And it only took less than [-] labor.

Looking at the railway from Chang'an to Luoyang, Li Er believed that you would not be able to build it for Yang Guang in ten years, but I, Datang, could finish it in one year.

So Li Er will not remind Li Yuanxing, he wants to let Li Yuanxing take a look at the potential of the people of Tang Dynasty.

A long railway, let the people of the world take a look at the might of my Tang Dynasty.

The road to Shu is difficult, and it is difficult to go to the blue sky.My Tang Dynasty, one day from Chang'an to Chengdu!

So Li Er wants to see with his own eyes that Yaozhou-made giant steel beast that can open mountains and dig holes. In one breath, he made a cave in the Qinling Mountains, leading directly to Shuzhong!

Li Yuanxing did not comment on the huge primitive shield machine.

According to Ma Yuan's mechanical ability has far surpassed Li Yuanxing, so Li Yuanxing will not talk nonsense, and dare not talk nonsense, not because he is afraid of losing face, but because he is worried that his words will affect Ma Yuan's decision-making.

"This thing is very important!" Li Yuanxing said to Cen Wenwen after reading the whole thing.

Cen Wenwen leaned back: "Your servant knows that the Holy Majesty is also concerned. The Ministry of Rites has already calculated the start date. At this time, it is related to the fate of the Tang Dynasty. No one dares to neglect in the slightest."

Li Yuanxing looked at other auxiliary tools, especially the machine for drilling holes in mountains.

There are also rail cars for transportation.

"This design is very interesting!" The cart for transporting gravel is not square or rectangular, but trapezoidal.

Ma Yuan’s explanation for this design with one end long and one end short is: “Your Highness, the empty cart is very light, and it can be pushed into the cave by people. Then it can be turned around at the machine’s discharge port, and then transferred to another path. On the track, hang the cable and pull it out of the cave.

As Ma Yuan said, he opened another loose button under the car: "Your Highness, this is a dump bucket. When the gravel comes out, it is directly dumped into the pit, and then transported away by other vehicles, enters the gravel machine, and is crushed. into a neat size, the gravel road under the railway still needs to be used.”

Li Yuanxing shook his head lightly: "My opinion is that the dome should be reinforced while advancing. Please refer to this opinion. If reinforcement is required, then there must be concrete and reinforcement in the car entering the cave. prefabricated panels, or stone.”

"Your Highness, the original plan is that the hole will be repaired after the hole is opened."

"What if there is a landslide due to vibration when the hole is opened?" Li Yuanxing asked back.

Ma Yuan was a little speechless.

After all, he is an expert in mechanics, and he is not good at architecture.Instead, Cen Wenwen interfaced: "Your Highness, this matter can be discussed with the craftsman in charge of construction in the Ministry of Industry. If you need to strengthen it while advancing, then you must consider whether this machine can be adjusted."

"Your Highness, the machine is easy to change. Originally, the second half of the machine is empty. It would be nice to add some shelves to make it easier for the craftsmen to work. The only trouble is that the feeding cart is a heavy one. How to send it in, let these small craftsmen think about it." !"

Li Yuanxing didn't say any more.

After watching the shield machine, Li Yuanxing hurried back to Chang'an, but left Wu Zhao and Li Lanshan in Yaozhou.

Late at night, when Li Yuanxing returned to Chang'an, the north gate of Chang'an City was not closed, but kept open and brightly lit.Qin Qiong sat waiting at the gatehouse of the city gate. Seeing Li Yuanxing coming back, Qin Qiong got into Li Yuanxing's carriage directly: "Wu Lang, your telegram scared me. There will be war in the north tomorrow. Could it be so sudden?"

"I'm afraid Gaochang people and Tuyuhun people feel more sudden!" Li Yuanxing said, and ordered to go back to the mansion.

However, Qin Qiong said: "The Holy Master, the Three Provinces, the Sixth Division, and several generals returning to Chang'an are all waiting for Wulang. The sudden start of war by the Western Turks caught us by surprise."

"Go to the palace!" After Li Yuanxing gave an order, he whispered: "You and I were caught off guard, but it doesn't mean that Fang Gong doesn't know. Fang Gong is in the north, and he can't fight. He is more ruthless in conspiracy than us, and he doesn't pass the news back. , it may be because he is afraid that someone will leak his information, maybe Li Xiaogong also knows that he must be helping Fang Gong."

After Qin Qiong listened, she immediately asked: "Could it be that, Wu Lang, you are prepared first!"

"I didn't prepare. I just asked Mr. Fang to go to the northwest and help me find the Turks in the west. I originally wanted to come, but it was also the New Year, so I was a little surprised so soon."

After listening to Li Yuanxing's explanation, Qin Qiong said with a smile: "Then it's not an accident, this is the planned strategy."

"Otherwise, I wouldn't have the audacity to snatch Fang Gong from the emperor's brother. There must be some changes in the West Turkic side that we don't know about, but Fang Gong must be aware of it."

Qin Qiong felt relieved.

After entering the palace, Li Yuanxing said so, and Li Er felt relieved.

Instead of blaming him at all, he said: "The general is out, and the emperor's order is not acceptable. Fang Gong is the pillar of the Tang Dynasty, and he has Wulang's plan, so it is natural to use it at the right time. One day earlier, one day later, it is not a big deal. It's just that I don't know whether the death of the Western Turkic Khan was planned or not!"

"Unplanned!" Li Yuanxing did not expect that the Great Khan of the Western Turks would die.

"This is trouble, big trouble!" Wang Jishan said suddenly. (To be continued.)
