Datang: I was exposed by Princess Changle

"The investment in road construction is huge, and the money and food consumed are simply impossible to estimate!"

"Even the treasury of the Tang Dynasty may not be able to afford it. How can merchants afford it?"

Changsun Wuji raised a question with a puzzled expression.

This is also what Li Shimin and others are puzzled by.

They believed that Lin Xuan had the ability to turn mud into stone, perhaps just like Xiangrui.

Incredible as it may be, such a solution may indeed exist.

Just like turning water into ice, they also thought it was a fairy art at first.

Later they learned that it was actually made of saltpeter.

Add saltpeter to water, and that's ice!

As for the deeper reasons, they are not clear.

There are also sugar cane harvested in Lantian County, some of which have already been made into sucrose.

The remaining part has to be kept as seeds and continue to promote planting.

Making sucrose is actually very simple, as long as the sugar cane is crushed, and then boiled, evaporated, aided in crystallization, and separated from honey, the four processes can be used to extract white sugar.

The craftsmanship of this white sugar is very simple and rough, and the color is also dark yellow.

But it is definitely sweeter and healthier than yam!

After seeing Lin Xuan's various magical methods, they probably all know that some things are not the fairy arts they thought.

Although it is quite miraculous, human power can actually do it.

This is not to say that they are doubting Lin Xuan's identity as an immortal. After all, Lin Xuan's ability cannot be explained by them.

Predict the future, seek good luck and avoid evil!

Striking the dead with lightning at a distance of dozens of steps!

These are called fairy arts!

"Uncle Guo is right."

"Even the construction of the Chi Road will cost a lot of money."

"Could it be that... this highway that turns mud into stone is more economical?"

Li Shimin asked curiously.

"That's not true. The highway costs more!"

Lin Xuan shook his head with a smile and sighed helplessly.

The raw materials of cement are limestone, clay, iron ore, coal and so on.

It is not difficult to fire, and it only takes six steps to get it done.

The prices of these raw materials are almost negligible, and only iron ore is worth a little.

However, the proportion of iron ore is not much, probably less than ten percent.

But compared with Chidao, cement must be more expensive.

After all, Chidao uses only two main materials—loess and wood.

Do these things cost a lot?

Obviously not.

As for the construction of Chidao, the only place where the cost is the most expensive is the corvee labor.

And these, the construction of highways also have to spend.

Plus cement, how much money will it take to repair it?

Lin Xuan pointed to the map and said with a smile: "This requires all the merchants in the world to contribute together!"

"Will they be willing?" Changsun Wuji asked.

"It's okay, when I issue an order, they will agree."

"When the time comes, I will order it to go down, and those who don't want to be beheaded!"

Li Shimin said in a relaxed tone.

Lin Xuan was speechless when he heard the words!

Simple and rude—this solution really deserves the imperial thinking!

Seeing Li Shimin's enthusiastic appearance, Lin Xuan had no doubt that Li Shimin could really do such a thing.

Then Lin Xuan scratched the back of his head, and said with a little embarrassment: "Well, I'm not this...that's what it means!"

"Don't worry, just listen to me."

Everyone stopped talking and looked at Lin Xuan directly.

They also really wanted to know what kind of resourcefulness Lin Xuan had?

How can merchants afford such a huge project that consumes financial, material and manpower?

Lin Xuan continued to talk eloquently: "First of all, let me talk about the method of turning mud into stone, and I will take it out."

"In each county, pick the right agent."

"Just like promoting tofu?" Li Shimin asked subconsciously.

"It's almost the same, but there are differences." Lin Xuan said calmly.

The technical content of tofu is completely incomparable with that of cement.

For tofu, there is only one agent in one state.

But the consumption of cement is astonishing.

As long as there are merchants willing to join in, he has no objection, the more the better!

"This method of making cement, I will give it out for free."
