"The Beijing-Hangzhou Grand Canal must be dug, but there is no need to dig so far."

"If you want to dig from Zhuojun to Yuhang, open up the four sections of Yongji Canal, Tongji Canal, Hangou and Jiangnan River, running from north to south, the total length must be at least four to five thousand miles?"

"For such a vast project, can your Majesty calculate how much manpower and material resources will be wasted?!"

This is only from Zhuojun to Yuhang, not counting other counties.

Counting all of them, Lin Xuan didn't even dare to think about it!

"This time the materials were mobilized from Changzhou to Cangzhou, the Yangtze River and the Huaihe River were taken first. For the rest of the journey, they were directly transported with the help of horses and bulls?"

Lin Xuan asked lightly.

"Yes."

Li Shimin nodded yes.

Of course he knew about it.

"Are you going to build this section of road into a driveway?"

"I'm afraid it won't work, not to mention that there are many mountain roads in the middle."

"There are still many places where the soil is loose and crumbles when touched."

"Once it rains heavily, the roads are easily damaged."

Li Shimin disagreed.

"No, let's build the highway!"

Lin Xuan laughed.

As he spoke, he pointed to a map of the Tang Dynasty hanging on the wall.

"Not only need to repair here. With the eastern capital Luoyang as the core, we also need to open up to Zhuojun in the north and Yuhang in the south!"

"Following the trend, it runs through the four sections of Yongji Canal, Tongji Canal, Hangou and Jiangnan River, with a total length of four to five thousand miles, and becomes the main artery that runs through the north-south traffic."

Chapter 274 Highway!

"Passing through the expressway is equivalent to opening up water transport in a disguised form."

"After the water transport journey is over, go directly to the high speed. In this way, the speed will not decrease but increase!"

It is indeed difficult to build a highway in the mountains, but it is not impossible.

It doesn't have to be like a highway, just pour an ordinary road with cement.

It is enough to ensure that the road is level enough to accommodate two carriages in parallel.

As for the rugged and winding mountain roads of later generations, let's wash up and sleep in a short time.

Don't even think about it, it is almost impossible to do this with Datang's current methods!

Everyone looked at the map and listened to Lin Xuan's eloquent talk, and they all nodded incessantly.

"Although you said a lot, the old man didn't understand a single word."

"How to repair this highway?"

"How can it be faster than Chidao?"

"And, aren't you afraid of rain and snow?"

Changsun Wuji asked with a puzzled face.

Lin Xuan looked back and found that Li Shimin was also in a daze.

Mad, say hi!

Forget about this crucial thing!

"The method of building this expressway is actually very simple."

"I have a way to turn mud into stone!"

"Used to build roads, you can build flat and spacious roads. Combined with steel and iron frames, you can also build dozens of stories high buildings!"

"Turning mud into stone?!"

Li Shimin slammed the table and stood up.His face was full of incredible colors.

How can it be? !

Can mud turn into stone when it dries?Is this magic?

"Using fairy art to build roads?!"

"After the mud dries, it is of no use at all."

"When a person walks over, they will be turned into ashes. How can they be turned into stone?"

Forehead?

This thing would have to be invented nearly 2000 years later.

It is normal for them not to understand cement.

"It's not fairy art, it's just some kind of method.

Li Shimin was at a loss for words for a moment, and then burst out laughing.
