Li Shimin's will: Li Zhi, the throne belongs to your brother

"Don't understand?" Li Shimin frowned, knowing that he was not a craftsman, but he could understand it.

It's too...

"Where can't you understand?" There was a trace of accent between the words.

"Your Majesty, I would like to ask, what is the unit of measurement for meters and centimeters?"

Duan Lun took the drawing and handed it to Li Shimin to ask.

Meter?

What rice?

Li Shimin frowned, why didn't he see it?

As a result, after drawing the drawings, Li Shimin discovered that the measurement units above were all units that he had never seen before.

I listened to Li Tai's explanation before, but I didn't read it in detail, and I didn't pay attention to this unit.

Li Shimin turned his head and asked inquiringly.

Li Tai just remembered that he seems to have fixed the weights and measures.

But before the urgent explanation came, Li Shimin handed it over to the Ministry of Industry.

"..." Li Tai could only find out the piece of paper with the unit of measurement from his sleeve under the gaze of the two of them.

"Earlier, Erchen said that the measurement was going to be changed, but now it has been changed, and all the new measurement units are used.

This is the unit of length, all in meters, all in decimal, the smallest is millimeters, followed by centimeters, decimeters, meters, ten meters, hundred meters... .

It is easy to remember, more accurate and easier to calculate. "

With that said, Li Tai handed the paper of weights and measures to Duan Lun.

"It's really troublesome uncle." Li Tai said apologetically.

"It's not in the way, it's not in the way." Duan Luncheng's frightened face eased a little, and he said that the relationship is very close or a family.

"Uncle, please get three catties of white ash noodles and borrow a charcoal stove. My nephew still has some things to get."

Li Tai said politely.

(In ancient times, it was awkward to call a nephew a nephew, so it was not used.)

"I'll get it here, minister." Duan Lun got up quickly, asking Li Shimin with his eyes.

After getting Li Shimin's permission, he called out and left.

Not long after, Duan Lun brought the stove and lime with two people.

"Father can do it."

Li Tai looked at the limestone powder in the sack and said.

"Then I will leave it to you, the emperor, and I will watch from the side."

"Yes, father." Li Tai nodded and said, then turned around and began to order the two temporary workers.

"Pour half a catty of lime flour into the charcoal fire, don't let the fire go out."

"Yes, Your Highness." The two craftsmen hesitated for a while, and then they did.

The lime component is calcium carbonate, and after calcination at a high temperature of more than 1000 degrees, it will become calcium oxide, which becomes the main component of cement.

The two craftsmen were full of big men, and they suspected that Li Tai was torturing people.

Because half a catty of lime is poured in, no matter how big the fire is, it has to be extinguished. How can such a small stove burn?

But he had to obey orders, so he could only keep adding charcoal.

And Li Shimin also showed a smile, seeing the thing fall and almost put out the fire...

This also calcined a hammer...

After working for a whole morning, Li Tai touched the lime, and finally saw that the white lime turned into a familiar gray.

Of course, it is also possible that there are too many impurities such as charcoal in it.

There may be a little more impurities, but it should not affect the use...

Thinking of this, Li Tai ordered to the two craftsmen.

"Pour the stove on the ground, get out the charcoal inside, put the lime in something, and get some bricks and a basin of water."

"Yes."

Although the two craftsmen didn't understand, they did it anyway.

The things were quickly placed in front of him, Li Tai smiled, and said to Li Shimin, father, the emperor should take care of it.

"I'm watching!"

Li Shimin waited for a long time, and after hearing what Li Tai said, he finally regained some energy.

After all, Li Tai poured the cement into the basin of water with a shovel.

As soon as it fell down, the cement was constantly rolling in the water. Li Tai took a wooden stick and started stirring.

too rare...

Li Tai looked at the slime and thought he had to add more.

So it was another shovel to get all the cement in.

Before Li Tai could stir it, the water began to bubble, and a puff of steam began to steam around.

Li Shimin's eyes widened, this... what's going on?

Why is there still smoke?

Not only Li Shimin was stunned, but even the craftsmen on the side were stunned. Why does this scene feel so fairy-like? ? ?

Li Tai was stirring seriously, and soon found out embarrassingly that there was still a little too much water...

You can add some sand and make it into cement slurry.

Li Tai was thinking about it when he saw the water began to chug and bubble continuously.

Soon, bubbles began to appear one after another, and within a few seconds, the water boiled! !

Li Shimin was stunned, this...how did you boil the water?

The craftsmen on the side were even more dazed, watching in disbelief.

The craftsmen in the distance, and the Royal Forest Army all looked at this scene in disbelief.

They couldn't figure out what kind of power could boil water out of thin air.

You know, there is no fire!

Only Li Tai knows that this principle is actually the principle of self-heating hot pot, the chemical reaction releases a lot of heat.

Hmm, maybe we should put some sand or something.

At this moment, a hand slowly reached into the basin.

Fuck it, don't hold it! ?

This is boiling water! !

Li Tai had quick eyes and quick hands, and he slapped away with a shovel.

There was only a sound of 'Dang', and the hand was slapped away. You could tell from the sound that it was a good hand.

Li Tai took a closer look, his eyes almost fell out.

The person who stretched out his hand was actually Li Er.

And he actually slapped Li Er's hand with a shovel...

"Da da ~ Escort!!"

The Yulin Army rushed over aggressively, grabbed the shovel from Li Tai's hand, and grabbed Li Tai's hands.

When Li Tai reacted, he found that he had been captured.

The craftsman on the side sat down on the ground in fright. This sudden change almost didn't scare the pee.

Suddenly, a murderous air permeated the air.

All the craftsmen felt that disaster was imminent, after all, they had witnessed this series of things happen lightly.

The scene suddenly fell silent.

On the other hand, Li Shimin shook his hands, looked at Li Tai with complicated eyes, and said to the Imperial Forest Army, "Back off."

The commander of the imperial forest army showed a look of embarrassment: "Your Majesty, do you want to call the imperial doctor?"

"No need."

"Yes!"

The Imperial Forest Army let go of Li Tai, and stood not far away, staring at him all the time.

Li Shimin stared at Li Tai tightly without moving his eyes.

"My lord, can you explain?"

He has never seen that water can boil like this, which is amazing!

Li Tai didn't dare to look Li Shimin directly in the eyes after regaining his composure, so he could only lower his head and explain.

"Uh, royal father, the water has boiled.

This son is helping you, if the emperor puts his hand in, I'm afraid...I'm afraid I'm familiar with it..."

Li Tai also looked aggrieved.

Who would have thought that Li Shimin would actually reach out and want to try...

If it weren't for my quick reaction, I'm afraid I would have to peel off a layer of skin on the spot. You must know that this is boiling water that has already bubbled! !

If you stretch out your hand, that's fine! ?

"So, you're still doing it for me?!" Li Shimin's voice was high.

"My son... my son... I know I was wrong!" Li Tai admitted his mistake on the spot. "My son is willing to be punished."

I forgot to tell Li Shimin to have this phenomenon, no one would have thought that Li Shimin would die like this...

Anyone with a little common sense would know that this thing is untouchable.

This is miserable... Not only is it useless, but you have to be punished...

What is this called!

"Hmm~" Li Shimin looked at Li Tai who bowed his head and admitted his mistake, and suddenly felt both exasperated and funny, full of lingering fear and shock at the same time.

Science, indeed, is miraculous.

Li Tai is really the reincarnation of a god, otherwise how could he boil the water?

The water is still steaming up to this day.

"Go on!" Li Shimin asked Li Tai to continue as if nothing had happened.

"Ah~" Li Tai was taken aback for a moment, and couldn't believe that he was not punished. From the corner of his eye, he glanced at Li Shimin who was expressionless and still rubbing his hands.

The craftsmen around looked at each other even more, their jaws almost dropped.

Unexpectedly, it was as if nothing had happened.

You know this is Li Shimin!

But the emperor!

Li Tai shrank his head, turned to the craftsman beside him and said, "Go and get some sand."

"Ah! Yes!" The two craftsmen staggered, thinking of going far away as if fleeing.

Soon, the two brought the sand as quickly as possible.

Li Tai began to add sand little by little.

Finally, in the eyes of everyone, the basin of water turned into sticky mortar.

Li Tai smeared cement mortar on the surface of the blue bricks, and then built them together.
