"This cannot be blamed on Your Highness. Charcoal is not easy to use. No matter how well it is designed, it cannot be compared to charcoal." Du Ruhui agreed.

"That's true, but the common people use this kind of charcoal to spend the winter. It's really hard for them. Even His Highness the King of Chu can't save the charcoal. Alas..."

Changsun Wuji sighed.

It is conceivable that in the cold winter wind, if the people kept such a charcoal fire, they would be no better than not lighting a fire.

Li Shimin also withdrew his gaze and nodded.

He looked at the saddle and then at the charcoal.

It seems that this brat’s world-famous private money cannot be easily researched.

Li Shimin sighed in his heart.

He turned around and looked at the wing in front of him.

"Open the room," he said.

Li Junxian responded quickly and walked forward quickly.

Changsun Wuji and the others also turned around and focused their attention on the wing to the west.

I encountered two failed scraps in a row in the yard. I wonder if there is a complete treasure in this room.

Everyone is looking forward to it.

but…….

"Your Majesty, do you feel that the temperature has suddenly increased a lot?"

"It seems to be even hotter than the summer days of the past few days."

Changsun Wuji suddenly said.

"Yes, Your Majesty, I'm sweating all over my back. The weather is really unpredictable. It's already autumn, but the temperature is still so high." Cheng Yaojin also scratched his head and agreed.

"No, no, it's hot all of a sudden. My butt feels a little hot." Wei Zheng wiped the sweat from his face.

"Your Majesty, Your Majesty, look behind you!"

"Stop standing here, or your clothes will be burned!"

At this time, Empress Changsun suddenly said anxiously from behind.

What?!

Everyone was startled and turned around quickly.

Li Shimin even took two steps back.

Boom boom boom…….

The flames shot up crazily.

This fire was extremely luxuriant and vigorous. With the puff and puff, you could see the air around the flame being distorted.

The charcoal that was originally full of smoke has completely burned.

The flames illuminated their cheeks, burning, very hot, as if it was summer.

"Gudong......"

Li Shimin swallowed.

The fire reflected in his eyes was like a volcano erupting.

This flame….

Even if it's charcoal, it can't go that high.

It was like a fiery snake, roaring towards the sky.

The flame tower made of eight honeycomb-shaped charcoal emits blazing heat.

The whole courtyard seemed to be filled with warmth.

"This..." Li Shimin was stunned.

Not only him, but the surrounding Changsun Wuji, Wei Zheng, Cheng Yaojin and others were also staring straight at the Flame Tower.

like a statue.

Looks shocked.

At a loss.

Who would have thought that charcoal could explode with such power.

It even looks stronger than charcoal!

"Is this really charcoal? How come His Highness the King of Chu's charcoal is more powerful than the ones outside!"

Wei Zheng pursed his dry lips and said.

"I don't know. I know about the pebbles in ordinary people's homes." Cheng Yaojin touched his beard with his hand. He felt that the beard was a little curled up, and continued: "The pebbles are really all smoke. That smoke

, rich and thick, absolutely incomparable to this charcoal."

Qin Qiong picked up a honeycomb charcoal, and when he worked it with a little force, the honeycomb charcoal broke into pieces.

Qin Qiong took another look with her fingers and saw clearly the ingredients inside.

I couldn't help but exclaimed: "Your Majesty, this is all made of charcoal, there are no other ingredients in it!

"

"Your Majesty, this charcoal...hiss..."

"The people can survive the winter this year, they can be saved, they really can be saved!

"

Qin Qiong shouted.

He, Cheng Yaojin, Yuchi Jingde and other military generals, none of them came from ordinary people's families.

We know very well the difficulties that people face during the winter.

Especially for those elderly people, winter is really an invitation letter sent to them by the Lord of Hell.

In one winter, I don’t know how many old people will die.

Winter is hard to endure.

For poor people.

But now, this honeycomb-shaped charcoal is really...

He directly burned the invitation letter from the Lord of Hell, and indirectly saved many people’s lives!

Li Shimin stared blankly at the flames.

Changsun Wuji, Du Ruhui and the others were shouting excitedly beside them.

"Is this thing easy to make?"

Li Shimin was silent for a long time and then suddenly spoke.

"Your Majesty, it shouldn't be difficult."

Empress Changsun walked over, with a round splint in her hand.

This plywood was thrown next to the coal.

It's just that they were all ignored just now.

Gently rolling up her sleeves, Empress Changsun squatted down, took the broken coal on the side, put it all into the splint, and then squeezed it hard.

A honeycomb trial is beginning to take shape.

Extremely convenient.

Extremely simple.

Extremely fast.

Li Shimin became excited.

He hurriedly walked over, took the plywood and tried it several times with his own hands, and it all came into shape.

"Gudong...this...this brat, what is really going on in his head? He can actually come up with this method."

"With such a simple change, the coal is still coal, but... it can burn so fully."

"Wonderful, I guess the secret of burning lies in these holes!"

"Although I don't know why, I feel so powerful."

After all, Li Shimin and others had never studied physical chemistry.

I don’t know if I need to drill more holes in order to ensure adequate air circulation during combustion so that energy can be obtained from more complete combustion.

They also don't know that these holes can make the fire even, and can completely burn a piece of honeycomb charcoal, so as to maximize the energy of coal combustion.
