There is no doubt about the construction of roads.

The greatest threat to rule in ancient times was undoubtedly transportation.

If the traffic is smooth, then the rule will naturally be smooth. Once the traffic is blocked, the country will inevitably fall into turmoil.

Transportation allows people to come and go easily, promotes communication and understanding between each other, and promotes the development of culture. These are necessary conditions for the unity and development of a country.

In history, transportation was often regarded as a factor in the formation and unity of the country and society. During the Qin Dynasty, "post roads" were built from Xianyang to all parts of the country, and it was stipulated that "cars and rails are on the same track and rails are on the same distance", so that people all over the country

Standardization of transportation facilities construction.

If Datang can connect the whole country and increase the speed of transportation to a higher level, then Datang's national power will undoubtedly develop unprecedentedly.

And this is actually a kind of open source.

Expressways in previous lives were able to charge fees, so naturally our Datang version of the railway can also charge fees.

At the same time, the construction of the straight road has promoted the development of people's livelihood in the entire Tang Dynasty. As long as there are no major problems, the national strength will undoubtedly be greatly improved.

Therefore, when I got Li Shimin’s affirmative answer.

Even Li Er directly allocated 100,000 yuan and 100,000 shi of grain, and Li Ming felt a little relaxed when he walked.

In his mind, he has already begun to figure out how to start his big infrastructure project.

The figure walked back to Prince Wei's Mansion.

I have stayed in the palace for long enough today, so it is naturally impossible to go to the Shaofu again.

Outside the palace.

Farewell to the complicated-looking Pei Juzu.

The figure walked back to the palace.

And this day passed quietly.

When the morning sun shines, a new day arrives.

Chang'an is still lively.

In Prince Wei's Mansion.

Li Ming opened his eyes.

Check in as always.

"Sign in!"

"Sign in successfully!"

"Congratulations on acquiring cement production technology!"

......

The sound of the machine echoed, and Li Ming's originally confused expression suddenly sobered up at this moment.

"Cement!"

His mouth opened slightly.

There was a look of astonishment on his expression.

He really didn't expect that someone would bring him a pillow while he was dozing off.

He had just started to prepare the infrastructure, and the system sent him the method of making cement.

Although there was a concrete production method in ancient China, its quality may not be much worse than modern cement, but the key lies in the cost.

The ancient version of concrete, the cost is simply ridiculous, what about glutinous rice, egg white.

It is strong, but the cost of this thing is so high that you doubt your life.

Cement undoubtedly does not have this problem.

Even if cement was fired in ancient times, the cost was extremely low. After all, in previous lives, cement firing in those rural earthen kilns was not necessarily much more advanced than that of the Tang Dynasty more than a thousand years ago.

Now the emergence of cement has undoubtedly directly solved a big problem for him.

It was even enough to instantly reduce the cost of building a straight track.

Originally, one of the biggest problems in the construction of the straight road was whether the sleepers should also be made of wood. Once wood is used, the cost will undoubtedly go up.

You don’t need wood, even if you use stones, the cost will not be much lower.

Nowadays, with cement, these problems have been solved.

After all, he is not really building railways now, but only roads.

It’s not a train running either.

It's just a carriage.

The requirements for sleepers are not that high, and concrete can also be used instead.

A smile couldn't help but appear on my face.

The figure also stood up immediately.

Wash yourself while being served by a maid.

Then he went out and went to the Shaofu.

The steps become more and more brisk.

At this time, Chang'an City was still prosperous.

But Li Ming was blocked by someone just as he took a step forward.

Li Ming looked at the little girl in front of him in confusion, unable to react for a while.

His King Wei was blocked, and he was still a little girl.

"Who are you?"

When the guard stopped him, Li Ming looked curiously at the girl in front of him, who was only thirteen or fourteen years old.

"Your Highness King Wei, you can't do this. You have bought all the eggs in Chang'an City, and we can't buy any eggs."

The little girl spoke angrily, and two cute dimples were revealed on her cheeks.

When he heard the little girl's words, Li Ming was stunned for a moment, and then laughed.

But before he could say anything, a girl from the front hurried over.

"Your Highness King Wei, I'm really sorry, Xiang'er is not sensible."

The girl's voice was like an oriole coming out of the valley, and there was a hint of uneasiness in her delicate facial features.

Although Qin Yuhuan is not afraid of the King Wei in front of her, but the little maid is just a slave, she is still a little afraid that the little maid will be punished.

"It doesn't matter, the egg thing started because of me. Can't you buy eggs?"

After speaking, Li Ming looked curiously at the basket in Qin Yuhuan's hand.

"Hmph, Your Highness King Wei, you still have the nerve to say that you asked the Shaofu to purchase a large amount of eggs. Who else in Chang'an can buy eggs in the past few months?"

The little girl seemed a little angry, so she couldn't help but speak.

"Xian'er, don't be rude!"

Qin Yuhuan spoke with a soft drink.

The little girl couldn't help but shut her mouth.

After scolding the little maid, Qin Yuhuan bowed slightly towards Li Ming.

"Your Highness, King Wei, please forgive me for your lax discipline!"

The words were spoken with a sense of nervousness.

"No problem!"

"By the way, if you want eggs, you can go to Shaofu to buy them. Now Shaofu has begun to sell eggs, or they should be sold in the West Market in a few days."

Li Ming didn't pay attention to the rudeness of the little maid, waved his hand, and then said casually.

In the past, eggs were purchased just to hatch chicks.

Now that the number of chickens and ducks in Shaofu has exceeded 100,000, there is naturally no need to continue to purchase them.

In fact, it started and stopped yesterday.

However, if farmers bring over eggs in the past few days, the Shaofu will still accept them, and will not stop completely until three days later.

So there are still no eggs on the market.

However, you can buy eggs by going to Shaofu.

Or in a few days, eggs will be available on the market again.

"Young Master?"

Qin Yuhuan breathed a sigh of relief at first, and then felt a little happy.

"If you are in urgent need, you can go to the Shaofu together with me, and ask the Shaofu to sell some to you."

Li Ming spoke nonchalantly.

His words made Qin Yuhuan's eyes light up, and then he nodded quickly.

"Thank you, Your Highness!"

Thank you quickly.

I haven’t bought eggs for several months.

Now that it is finally available for purchase, Qin Yuhuan is very happy.

"It's just a small matter, come with me!"
Chapter completed!
