Datang: Li Shimin begged me to rebel

"If we can't dig a mountain, then we can dig through it!" Li Ke looked at Yan Lide and said, "If we can't avoid a mountain, we can just dig into a tunnel. Tunnels are not too rare a solution."

Yan Lide and the others were a little dazed, digging a tunnel?Digging directly through the mountains?this……

Well, the difficulty is much lower than directly opening the mountain, but not much.

Li Ke didn't think it was so difficult. Who gave him the experience that countless predecessors tested with their lives?Only when he came to ancient times and implemented these techniques did Li Ke realize that although the techniques are precious, what is equally valuable is the experience he has accumulated over a long period of time!

There is no trick to go with these experiences, but once it is summed up, the cost savings or others are very huge.

Take tunneling as an example, let alone high-end product shield machines, the use of shield machines to excavate tunnels is relatively limited. Even in the era when domestic shield machines dominate the global market in later generations, most road and railway tunnels are still It is carried out by traditional excavation method.

But many people should have an impression, at least Li Ke remembers reading many stories about construction soldiers digging tunnels, tunnel collapse and rescue when he was a child.

But after entering the new century, engineering tunnel collapse is almost unheard of, which is brought about by technological progress and experience progress.

The new detection technology avoids more dangers, and the most important improvement is the construction sequence and plan during the tunnel excavation process.There are some technologies and principles that are not difficult, but they have not been discovered or researched before.

It can be easily implemented after the research is done.

In fact, the modern shield machine of later generations is a kind of machine obtained by combining the gradual optimization of human tunnel excavation procedures.

Although the world's first shield machine was invented as early as the [-]th century, the gap between the two, as well as the construction process and sequence, are too great.

It's almost the same as the difference between fireworks and cannons. The principle between the two is the same, but the technical gap is not a little bit.

Li Ke has a complete tunnel-digging process in his hand, and more importantly, he has the national exploration data on various geological structures in his hand, and these exploration data are preserved.

Therefore, the tunnel can also be dug slowly in the future, as long as the forging control method of high-strength cement is solved.

"It seems that according to what His Highness said, the finances of the Tang Dynasty will probably be short of money in the next few years." Huangfu Lin said with a wry smile. It doesn't take much to know that the cost of digging tunnels and building bridges is very high.

A Weihe Bridge requires two reservoirs, but the Yellow River Bridge must not be doubled?It might not be cheaper to dig through a big mountain than a bridge, right?Now Datang Finance's annual income is only two treasuries, a bridge will cost four treasuries, and how much will it cost to build railways all over the country?

Thinking of the horrible financial consumption, Huang Fulin couldn't stop smiling wryly. When the finances were tight, wouldn't he be under a lot of pressure as the Minister of Finance?

Huang Fulin's words made everyone look at each other in blank dismay, as if it was indeed such a fact.

"Of course, it is inevitable that Datang's finances will be short of money, but this does not affect our national railway construction. My personal opinion is that Shangshu Province will promote a national railway construction plan, which will be implemented in several years."

"For example, the infrastructure construction plan of 40 billion yuan, or the infrastructure construction plan of 400 billion yuan, etc." Li Ke said with a smile.

Everyone was numb when they heard this number, let alone 400 billion, 40 billion... I am afraid that Datang's finances will take decades?Even if Datang's finances are increasing every year, this is too scary.

"This...Your Highness, think twice. I don't think we can do this. It's not that the old minister opposes the construction of the railway, but can our plan not be so radical? We can take this time to complete in 20 or even 30 years."

"The rise of an empire can't be achieved overnight. Governing a big country is like cooking a small fish. If the steps are too big, a country will easily collapse. Therefore, I feel that this matter should not be too fast, but should be based on stability." Wei Zheng came out to object on a rare occasion.

Li Ke glanced at him, Wei Zheng: "..."

Your Highness, you see that I am useless, I have to object to this.

After a pause, Wei Zheng asked hesitantly, "Or, Your Highness, do you have a better way?"

"Oh, I don't want to say it." Li Ke sighed and said helplessly.

Everyone: "?"

Everyone looked at each other in blank dismay, wondering why His Highness made such a statement, what is there not to say?Only by speaking out can we know how to implement it.

"You haven't learned a lot of the knowledge I've given you." Li Ke sighed and shook his head, looking like a child who can't be taught.

Seeing Li Ke's pretentious appearance, Li Shimin's head was full of black lines. He almost kicked him, but luckily he held back.

I kept muttering a few words in my heart, "Let him groan", "Let him grovel", "This is a good thing", "It's all a good thing".

"Forget it, let me tell you the truth, when I renovated Chang'an City, do you remember?" Li Ke said lightly.

"Remember." Everyone nodded and said.

"Do you know how much I spent?" Li Ke asked lightly.

"More than 800 million guan." Everyone said one after another. Didn't your Highness announce this number?Although they guessed that this number may be different, especially now that His Highness has asked, there must be a difference, but they don't know the exact number.

"I didn't want to tell you, but there are some things you can't understand. If that's the case, then I'll show my cards, and I won't pretend. I'll tell you directly. Strictly speaking, I didn't spend a penny to renovate the entire Chang'an city. If I have to say it, I probably made some money." Li Ke said lightly.

"Ah?!" At this moment, everyone was completely stunned, didn't they spend a penny?You still make money?

Everyone was stupid, their heads couldn't figure out how Li Ke managed to spend no money, it's impossible!The roads in Chang'an City, the walls of some square cities, and the dilapidated houses of many people were all refurbished by the way. Those people's manpower and material resources were spent, but you told me that they didn't spend money?

This is impossible!Everyone looked at Li Ke in shock!If Li Ke hadn't said this answer himself, they would never have believed it anyway.

Even Li Shimin was a little shocked. Li Ke told him about it, but Li Ke didn't explain it clearly at the time, let alone in detail. Li Shimin just thought that Li Ke's cost was far lower than the outside world's expectations, and he didn't spend 800 yuan. Wan Guan, it may have cost 200 million Guan.

But... did not spend money, but also made money?
