"His Royal Highness the Prince, what are these things for?"

The coal stove was moved to the courtyard, and Wang Ben and others watched around for a long time, raising their heads and asking suspiciously.

"Just watch!"

Ying Feiyu smiled, beckoned the soldiers to light the fire, and brought a pot of cold water over.

I saw that the soldiers first ignited some firewood with flammable products, and then used tongs to pass through the small hole of honeycomb coal, and sandwiched two pieces on top of the firewood that had been lit!

Open the air inlet and let the wind continue to flow in, and after a while, the honeycomb coal will be ignited.

"Alright, put the kettle on it!"

Seeing that the fire of honeycomb coal was growing, Ying Feiyu commanded.

"Yes!"

The soldiers did as they were told.

The old goods gathered in a circle and watched quietly.

The coal stove was not large, not much larger than the wooden barrels used to carry water in this era.

And they just saw that they only put two pieces of honeycomb coal in it, how much firepower can this have?

A pot of cold water is estimated to take a long time to boil!

To their surprise, after a while, there was a sizzling sound in the kettle, and it was obvious that the water in the kettle had begun to heat up.

The veterans looked at each other in surprise again!

After a few more moments, the water in the pot began to churn gradually, and the lid on the top kept jumping!

"This ...... Is this boiling? ”

A couple of old guys stared at the kettle in disbelief.

"If it's boiling or not, won't you open it and see if it's going to know?"

Ying Feiyu carried her little hands and said with a smile.

"That's right, Lao Kang, you have thick skin, you come to fight!"

Zhang Han said with a smile.

"Hey? Who do you say is thick-skinned? They are all military generals, why should I be opened? When it comes to cheekiness, you old picker should be thicker, right? ”

Hearing him sarcastically mock himself, Kang Anping immediately stopped doing it and went back directly.

"Who do you say is thick-skinned?"

"Just say you, what's wrong? Not convinced? ”

"Of course I'm not convinced, you ask everyone, if you talk about cheekiness, who is the thickest among us?"

Just because of lifting the lid of the pot, the two of them quarreled with each other.

Ying Feiyu is used to such a scene.

Above the court, they should not delay in arguing in front of the scumbag, let alone in his other garden!

The other old guys are the same, not only do they not stop it, but they also look lively with relish!

In the end, Meng Tian, who had just joined not long ago, spoke out and stopped their quarrel, "Okay, don't quarrel, let's open the lid of the pot and find out!" ”

Without the barrier of the lid of the pot, the water splashed suddenly, and the hot air was also released instantly, rising!

One by one, the old guys lowered their heads and looked into the kettle, feeling the heat waves!

"How?"

Ying Feiyu asked with a leisurely smile.

"It's on! The water is really boiling! ”

"Just two small pieces of coal, and a full pot of water can be boiled in a few moments? What the hell is going on? ”

"That's it! On weekdays, we have to drink tea, and tell our subordinates to boil the water for half a day, why does this honeycomb coal ...... so quickly? ”

The old guys asked questions.

The speed of boiling water is what they are watching, and they absolutely can't fake it.

I just don't know why!

"I'll talk to you about this prince later!"

Later, he instructed his subordinates to ask the cook to come with the ingredients, and he personally fried a few dishes.

It's faster than firewood in the kitchen!

"The firepower of this honeycomb coal is so fierce?"

One dish after another was fried, and Wang Ben's eyes suddenly lit up.

"The fire is one of them, haven't you noticed that from the beginning of boiling water to the present, those two pieces of coal have been burning?"

"Hmmm! You seem to be true when you say that! ”

After Meng Tian said this, the old goods nodded suddenly, and the shock in their eyes was even worse.

"In this way, honeycomb coal is much more convenient than burning firewood, two pieces of honeycomb coal can boil water, and can also cook, and there is no need to add coal halfway! And firewood needs to be added constantly! ”

"That's right! As long as the price of honeycomb coal is not high, it is definitely a blessing for the people! ”

"Yes, yes, this thing is a consumable, it needs to be used for many years, if the price is high, the people would rather trouble a little bit, go up the mountain to chop wood and burn ......!"

After showing everyone the usefulness of honeycomb coal, Ying Feiyu called a few old people together and tasted a few dishes that had just been fried.

During the banquet, the old goods opened their mouths one after another to evaluate the honeycomb coal.

By now, the veterans have fully understood Ying Feiyu's intentions.

It is planned to transform the coal, make honeycomb coal, and then sell it to the people!

In this way, it is not only convenient for the people, but also solves the problem that there is no market for coal mines!

"The cost of each piece of honeycomb coal is a little more than a penny!"

Ying Feiyu took a bite of the scallion fried mutton in front of him, and said slowly.

"How much?"

Hearing this, several old guys were immediately startled.

With such a fierce firepower, the cost of honeycomb coal is only a little more than a penny?

It's cheaper than buying firewood!

"The craftsmen have calculated the cost, and on average, the cost of each piece is about one and a half pennies, and it should be no problem to sell it for three pennies, and the price is acceptable to the people!"

"In addition, you have also seen the air holes on the coal stove just now, open when you use it, close it when you don't use it, and the honeycomb coal that is not burned will burn at a very slow speed, and you can open it when you use it next time!"

"If used properly, two pieces of honeycomb coal will last a whole day!"

Ying Feiyu explained with a smile.

"Two pieces can last a whole day? Boiling water and cooking are all counted? ”

Feng Quji asked in surprise, thinking that he had heard it wrong.

As a result, Ying Feiyu nodded firmly and gave him an affirmative answer!

That means that as long as six cents, it is enough for a family to use it for a day! Well! I believe that the people can afford it! ”

Now that the grain yield is high, the people have a lot of side jobs, their incomes are rising, and their lives are getting better and better.

"Your Royal Highness the Prince, do you have to use the bucket-like stove just now to use honeycomb coal?"

Wang Ben suddenly remembered this and opened his mouth to ask.

"My father-in-law is right, it's called a coal stove, and it's specially made for the use of honeycomb coal! Another scissor-like thing is called tongs, which are specially used to take honeycomb coal! ”

Ying Feiyu explained the other two things.

"I wonder how much the coal stove and tongs are worth?"

"It's free!"

"What? Gratis? ”

This sentence once again shook the jaws of the old guys.

The workmanship of the coal stove and tongs is not very complicated, but it also requires a cost.

If it's free, wouldn't it be a loss?

"Your Royal Highness the Prince, if you are not mistaken, it takes a lot of iron to build tongs and coal stoves, right? Just send it for free? Haven't all the people of the Great Qin come to receive it? ”

Zhang Han made a bitter face.

It is they who want to solve the coal market, and I don't know if the honeycomb coal can be sold at that time, but the coal stove must be flocking, and the money is not earned, but it is the first to lose a lot of money!
