Since Cao Ze helped Lao Li's father and son ease the relationship, Uncle Li Yuan and Uncle Li gave up the Taiji Palace.

Li Shimin, the emperor, finally moved into where he should go.

Inside the Imperial Study.

Li Shimin was watching the recital, when there was a sudden sound of footsteps in his ears.

Li Shimin's heart suddenly felt unhappy.

What about Wang An's hair?

I don't report anyone when I come, do you want to do it?!

And who is so bold that he dares to come in without waiting for Xuan?!

Li Shimin raised his head unhappily and happened to see Cao Ze with a smile on his face.

Li Shimin was relieved.

No wonder......

I told me at the beginning that there is no need to report when the national teacher comes.

"What gust of wind is blowing the national teacher today?" Li Shimin hurriedly got up and greeted him: "Wang An, quickly serve tea!" ”

Cao Ze can take the initiative to come to him, this is really fresh!

"It's all my own people, so I don't have to be so troublesome." Cao Ze said politely: "I'm here this time, but I have something good to show you." ”

"What's good?"

Li Shimin's ears suddenly stood up!

"The first one is the cement I told you about before." Cao Ze smiled and took out a stack of papers: "How to do it, it's all written clearly." ”

"Cement?!"

Li Shimin was excited all of a sudden!

When he asked about the situation in the Zu'an Immortal Realm before, Cao Ze mentioned cement.

That's a good thing!

It can be used to build houses, or it can be used to build embankments, walls, etc.

By the way, there's also that road repair!

Convenient transportation can promote the development of commerce, and the development of commerce can drive the economic development of the entire Datang.

Although Datang now pays attention to Shinong industry and commerce, it does not affect Li Shimin's understanding of the importance of business.

When he bragged about firing guns before, Cao Ze had told him these things more than once.

Moreover, after the transportation is convenient, the mobilization of the army is also more convenient and faster.

If there is any chaos in the future, you can guarantee that you will send troops to suppress it as soon as possible!

Of course.

Now that he has the big killer of black powder, Li Shimin is not afraid of anyone doing things at all!

And with the popularity of a series of items such as potatoes, snow salt, Quyuan plows, etc., now his reputation among the people is getting better and better.

The chances of rebelling against Shenma are very small.

If it weren't for the fact that life couldn't go on, who would have done this with water in their brains?

When the cement house and cement road are repaired, there will be a big wave of people's hearts!

Li Shimin felt that his position was completely stable!

"And what about the second?" Li Shimin asked excitedly.

Since Cao Ze started with the first, there must be more later!

"This second one is even more remarkable!" Cao Ze came up with a second plan: "Steelmaking technology, I think you must be very interested." ”

Li Shimin took the stack of papers, and the whole person trembled!

There's no way, Datang is really short of steel!

In this year's war, the vast majority of soldiers were armourless!

I can barely get a leather armor to deal with, and some don't even have leather armor!

As for weapons, that's even more to say!

The weapons of ordinary soldiers are at most stronger than scrap metal......

And Cao Ze came up with the steelmaking technology, quality and output naturally do not need to be asked.

This has been proven many times before.

With this technology, he can arm the army of the Tang Dynasty from head to toe!

Think about it.

A team armed all with steel, what kind of concept is that?!

The enemy can't be hurt by swords, and arrows can't shoot through!

It's simply invincible!

Such a team is something he never dreamed of before!

Coupled with the black powder bomb that he just started, the Tang Army can simply push sideways in the future!

Goguryeo, which Yang Guangsanzheng didn't win back then, is no longer a problem!

If the output is sufficient, a part of it can be divided into civilian use.

Not to mention anything else, with the tools made of steel, it must be easier and more efficient for the people to farm.

And Cao Ze also said.

Building a house with cement or building a city wall, a dam, or something is inseparable from steel reinforcement.

"What about the third......?" Li Shimin asked expectantly.

"It's gone." Cao Ze said disdainfully: "Don't be too greedy!" ”

Li Shimin was embarrassed for a while, but it was quickly covered up.

Anyway, it's not the first time Cao Ze has teased him, he has long been used to it.

And for these two things today, no matter how much you are ridiculed, it is worth it!

"I brought you something, as for how to distribute the arrangement, you can see for yourself." Cao Ze opened his mouth and said: "Let me say a word here, if it is a military or civilian facility, it will be counted, if it is the part that is sold, it is still the old rule." ”

After all, the manufacture of cement or steel also involves the cost of raw materials and labor.

If it is used to repair the river dam or give it to the armed army, it is not appropriate for Cao Ze to ask for money again.

The army protects the people, and the river dam also protects the flood.

And the people are the basis for him to make more money in the future, and they also echo his plan to develop and transform Datang.

Only the part that is used for commercial sales will be distributed in accordance with the old rules of 91.

"That's nature, that's nature." Li Shimin said yes again and again.

He wouldn't care about any of that.

Even if he doesn't make a dime, he is extremely happy!

The next moment, Li Shimin suddenly thought of something.

The excitement was extinguished in an instant.

"Then these two technologies, the price is ......"

The value of these two technologies is no worse than that of black powder.

Before, he relied on reselling the family's wine, and Lou was able to scrape together the money to buy the black powder formula.

There's really no money now......

As for going to the treasury......

Before, Cao Ze's things had not been able to directly generate revenue for the treasury.

Now the treasury is still empty, and the rats are disgusted.

If he proposed to spend the treasury money to buy these two technologies when he was in the court, Dai Zhou was afraid that he would cry and make trouble on the spot......

"Don't worry about that." Cao Ze comforted: "These two technologies are free, no money." ”

The reason why the formula of black powder was sold to Li Shimin was because he lacked money to conduct a special lottery at that time.

Now that he is not so short of money, he naturally doesn't care about it.

Of course, the main reason is that today he drew a big sniper.

Happy!

Besides, if Li Shimin doesn't do this thing, he has to do it himself.

When the time comes, not to mention the trouble, it will lead Li Shimin to ponder in his heart.

Anyway, now that he is completely relieved of Li Shimin, it doesn't matter if he gives it to him directly.

When the output of steel catches up, wait for the money to be counted!

In the future, there will definitely be a large area of reinforced concrete houses in Datang, just for this, he will be able to make a lot of money!

When various manufacturing industries develop in the future, it will be needless to say!

In the future, money will really be just a number for Cao Ze!

"Auxiliary." Li Shimin immediately handed over the steelmaking technology: "The matter of new steel will be handed over to you." ”

"Minister, I will live up to Your Majesty's trust!" The eldest grandson Wuji solemnly took it.

In fact, when Cao Ze said that it was steel just now, he understood why Cao Ze pulled himself into the palace this time.

For this new steelmaking technology, the eldest grandson Wuji also attaches great importance to it.

Money or something is secondary.

The main thing is that this thing can firmly bind the relationship between himself and His Majesty and the National Teacher, which is of great benefit to the eldest grandson's family!

At least when that day comes, I can close my eyes with peace of mind.

After all, he has lived most of his life, and many times he has to think about future generations.

"As for the production of cement...... Li Shimin muttered: "Just leave it to Duan Lun." ”

After listening to this, Cao Ze looked at Li Shimin in disbelief for a year.

it!

Is this a human thing?

Did Duan Lun offend you in something, so you planned to exhaust him to death?

Duan Lun, who was busy supervising the bomb in another palace of the Imperial Palace, sneezed fiercely at this time......

"I'm so happy today!" After the incident, Li Shimin said excitedly: "National teacher, auxiliary machine, why don't you stay and have a few drinks with me!" ”

At this moment, Wang An hurriedly rushed in with a letter.

"Your Majesty, eight hundred miles urgent!"
