Datang: I was exposed by Princess Changle

In the future, he will come out with a traffic light, which is also a good way to promote the progress of the Tang Dynasty!

Li Shimin opened his mouth when he heard the words, but didn't say a word for a long time.

Although Ma Xiu's opinion is taken for granted, it is a good idea.

But it's hard to implement!

If you want to do this, you have to double the width of the road!

easy to say, hard to do!

How much manpower and material resources will be invested in this?

How long will it take to get it done?

Simply immeasurable!

Naturally, some people jumped out and refuted Ma Xiu with this reason.

After you sing, I will appear on stage.

Li Shimin ate and drank and listened to the heated discussion of his classmates, but found it very interesting.

These students dared to express their views in front of him, such courage is rare.

commendable!

It's better than some pedantic courtiers and officials who only know blind flattery.

The fact that these students are so bold is because they only regard Lin Xuan as the principal of the school.

In front of the teacher, they have always been more daring.

All the teachers are also very approving of their courage to express their opinions.

It doesn't matter even if you say something wrong, as long as you dare to say it.

This is their good school spirit.

"I think the best thing now is water transportation."

"The transportation capacity of building ships and cargo ships is far better than that of land, but what needs to be considered now is how to dig out unimpeded rivers?"

Lin Xuan: "..."

Hearing what Cui Hao said, Lin Xuan directly sprayed Li Shimin all over.

What the fuck? !

Brother, you are really outstanding!

Is this the rhythm of digging canals?

Back then, Qin Shihuang began to dig Lingqu in 218 BC.

Mainly to transport the troops and materials needed to conquer Lingnan, Shi Lu was ordered to dig a canal to connect the two rivers of Xiangli and Lishui.

Later, it was successfully developed in 32, and it took four or five years.

Lingqu can not only transport, but also irrigate the fertile fields along the road.

Cui Hao would put forward this idea because he wanted to build a villa for Lin Xuan at that time.

Cui Hao and Xu Yuan teamed up, and Lin Xuan led them to change the stream.

If streams can be diverted, why not rivers?

The water of the big river floods every year, and I don't know how many people along the banks will drown.

If new river channels are opened up, this situation may be alleviated.

Moreover, transportation capacity can also be enhanced.

Cui Hao grew up in the water since he was a child. Because of the training of the river husband, his water skills are quite good.

The main force of transportation this time is actually water transportation.

If there is no water in some places, they will stop on the shore and then change to land transportation.

Li Shimin frowned and thought hard, carefully considering the plan Cui Hao said.

Digging a canal? !

Chapter 272 Get through the waterway of the entire Tang Dynasty?Whimsical!

Yup!

It took a lot of effort to build Chidao.

It seems that some Chidao are built in the middle of the mountain stream, and if you don't pay attention, it will be a deep abyss.

The plank road in Shu County is thousands of miles long!

Digging a river channel is much simpler than chidao plank road.

Although it also consumes a lot of manpower and material resources, it is simple and rude.

Grab a shovel and get going!

The students discussed it for a long time, but in fact, Cui Hao's method is the only way, which sounds more reliable now.

Li Shimin couldn't help nodding.

When the students went back to rest, Li Shimin hadn't finished eating yet, so he ate hard.

He ate all the fish balls, but Lin Xuan actually ate two of them.

At this point, Li Shimin was still complaining, saying that with these hot pot ingredients, he could only make a toothbrush. There were too few things, and complained that Lin Xuan was stingy.

Hearing this, Lin Xuan wished he could stuff the hot pot base into his mouth.

More than 100 fish balls, can you eat so much?

And you said he was stingy?

It's you who can eat too much, okay? !
