I'm a marquis in Datang

Du Qi ordered: "Bring it in!"

After finishing the words, I saw the little eunuch outside the Ganlu Hall entering with a cement slab in his arms.

With a bang, the cement slab fell to the ground.This stone slab made of cement is the latest formwork, mixed with sand and stone, it can already be called a concrete stone slab, about four feet long, two feet wide, and two inches thick.

The surface of the slate is smoothed, and the surface is smooth after the cement has dried and hardened.

Du Qi pointed to the cement board and said, "Your Majesty, this is a model. The road from Chang'an to Lantian County in the future will be all

Such a slate, and the thickness will be thicker.Even if there is thunder and rain, walking will not be affected. "

Looking at them one by one, they all stared wide-eyed, with incredible expressions on their faces.

Not dirt roads.

It may not be easy to build a road with such stone slabs.

Li Shentong looked over, and he snorted and said, "Du Qi, what are you pretending to be doing? It's not just a polished stone. It takes too much engineering for you to mine stones to build roads. It is extremely difficult to lay stones on the road. "

Everyone looked at Du Qi in unison.

They all thought they were stones.

Chapter 504 Li Shentong Is Isolated

Li Shentong is isolated

Li Yuan was also curious, walked out of the seat, walked in front of Du Qi, and looked down at the stone slab on the ground.He looked at the slate at this moment and said, "Erlang, is this a slate?"

Du Qidao: "Your Majesty, this is naturally not a stone slab. If the road is paved with stone slabs made of quarrying rocks, it will be too difficult to build the road. Let alone 150 million guan, even if it is 300 million guan, it will be repaired."

"This stone slab is a concrete slab made by the craftsmen in my house who spent their whole life developing it by mixing sand, stones, etc., and then pouring it out."

"The situation of the stone is clear to everyone."

"This cement board is extremely hard, and it is difficult for ordinary swords to break it."

Du Qidao: "This kind of slate paving can ensure the stability of the road from Chang'an to Lantian County, so that the road will not be repaired every year, and it is poured. The road on the official road is not paved with stone slabs one by one, but poured. , In this way, the road is more stable, and the ground is also stable. At that time, the carriages can travel fast, and they will not be affected by the weather, and the journey will be faster."

Li Yuan said: "Really?"

Du Qi said: "Naturally it is true."

After a pause, Du Qi continued: "How dare you deceive Your Majesty about such a thing. After all, road construction is aboveboard. Thousands of people will be able to see it, and His Majesty can check it at any time. You can't hide it from anyone."

Li Shentong snorted and said: "Du Qi, the surface of your stone slab is very smooth. I'm afraid that people walking on it may slip, and when the time comes, the carriage will slip even more when driving."

Du Qi sighed: "Prince Huai'an, if you don't speak, no one will regard you as dumb. Once you speak, it will only show your shallowness in the end."

"you…"

Li Shentong was very upset.

Li Yuan saw it in his eyes, and a smile flashed in the depths of his eyes.

It is true that he highly values ​​Li's supernatural powers.

During this period of time, Li Shentong was quite domineering. Li Yuan didn't want to see such a result. It happened that Du Qi and Li Shentong had conflicts, so he could use Du Qi to beat Li Shentong.

Du Qi continued: "The surface of this kind of concrete slab made of cement should be rougher or smoother. It is up to me to make the final decision.

can be determined.This slate is just a sample.On the surface of the real road, scratches have to be left, and if there are scratches, the carriage will not slip when waiting on it. "

Li Yuan nodded.

He stroked the beard under his chin, with a look of approval on his face.

A light flashed in Li Shimin's eyes. He has roughly understood the benefits of this stone slab, and even Li Shimin himself is very proficient in governing the country. It’s convenient, it’s just that this way of building roads, compared with the original way of building roads, what advantages does it have? After all, you pay for the money.”

Li Yuan nodded and said, "Yes, where is your advantage in building roads?"

Du Qi knew that it was Li Shimin who deliberately paved the road for him and let him talk, Du Qi said: "Your Majesty, King Qin, I won't talk about the money I want to make from building the road, just talk about handing over this road to me." What good will it do if I come to build the road?"

"First, to achieve the effect of work-for-relief."

"Under normal circumstances, corvee is enlisted to build roads, and countless people come from their homes to build roads. Not to mention the question of whether people will die or not, at least the people's homes will be more difficult because the males are taken away."

"The way I build roads is to recruit people to work with money. In this way,

People work to earn money to support their families.This method ensures that although they speak out and do things, the money they earn is enough to support their families. "

"It is a great help to some families who have difficulties in their families, have males, and have little land and nothing to do."

"Giving them the opportunity and ability to support their families."

Du Qi looked around, his gaze finally fell on Li Yuan, and said, "Your Majesty, what do you think?"

Li Yuan said: "Erlang's plan can indeed achieve the effect of labor relief. Especially this road, from Chang'an to Lantian County, requires a lot of manpower to participate. At that time, the common people will be able to make money. Not to mention how much they earn , but at least they can support their families while building the road."

Du Qi said: "Your Majesty is wise!"

After a pause, Du Qi continued: "The second benefit is to make the transportation more convenient and promote the commercial development of Chang'an, Lantian County and surrounding areas."

"The original dirt road, although the road is passable, is actually not easy to pass through."

"The horse-drawn carriage is too bumpy, but after the road is repaired, the carriage can run smoothly and travel more easily. Many merchants, even ordinary people, can easily travel to and from Chang'an, sell goods, and promote commercial development.

It is more prosperous, and it is easier for the people to make money. "

Du Qi said seriously: "This is the second point of convenience, what does Your Majesty think?"

Li Yuan said: "It can indeed be achieved."

Du Qi continued: "The third point is the convenience of military operations."

"There is no war in the vicinity of Chang'an today. But no one can guarantee that there will be any emergencies. Once such a thing happens, no matter it is windy or rainy, no matter what the weather is, the team can follow the official road Quick travel can save a lot of time. Once there is a war, time is life."

"A little more time means more opportunities."

"The convenience of running a carriage can make it more convenient to transport supplies."

Du Qi said: "In addition to the third point of convenience, there are actually many other conveniences. They are all small aspects. I will not elaborate on them one by one. The convenience of these three points alone is already very good. Especially The imperial court does not need to collect corvee, it will not increase the burden on the people, the imperial court is not under pressure, and this is the most important thing.”

Li Yuan nodded.

At this time, he was already in a heartbeat.

Because for Li Yuan, he doesn't need to take care of anything, and he doesn't need to pay anything to get things done.
