"Your Majesty! See the Queen! ”

In the Ganlu Palace, Li Zexuan saw Li Er and Empress Changsun walking out of the back of the main hall together, he quickly retracted his gaze and bowed to the two.

"Hmmm! Excuse me! ”

Li Er waved his hand, and then couldn't wait to get straight to the point: "I heard that you are here to offer a treasure today, but why haven't you seen the treasure?" ”

Although Li Zexuan is young, he is a complete traitor, and it is usually difficult to take advantage of him, but now he actually took the initiative to "send it to the door", Li Er really wanted to know what kind of surprise Li Zexuan sent!

Li Zexuan said solemnly: "Your Majesty, the thing sent by the minister today is a bit big, and it is still outside the palace, please ask Your Majesty to let the minister carry it up!" ”

"Oh~? Fast! Zhao Song, quickly let people bring in the things brought by Yong'an Hou! ”

When Li Er heard this, he immediately spoke up.

A bit big? He now wants to know more about what Li Zexuan brought!

Zhao Song took the order, and after a while, he walked in with four little eunuchs carrying a coal stove and a basket of briquettes.

Li Er couldn't help frowning when he saw that the eunuchs had brought up an iron lump and a basket of black things, because these two things didn't look tall at all!

With a slight displeasure in his heart, Li Er walked down from above, looked at Li Zexuan with unkind eyes and asked, "This is the treasure you want to give to me~?" Hey? What a special charcoal stove! ”

But it was Li Er who was halfway through his words, only to find that there was still a fire burning in the stove, and he couldn't help but sigh.

Li Zexuan arched his hand and said: "Your Majesty, this is not a charcoal furnace, this is a coal furnace, and coal is burned in it!" ”

"Coal~? How can a coal fire be so vigorous~? ”

Li Er is not the kind of Emperor of the Deep Palace who is ignorant of the world, he immediately frowned and disbelieved when he heard this.

At this time, the eldest grandson also walked down from above, she carefully looked at the honeycomb coal in the bamboo basket, and said after a while: "Your Majesty, the briquettes brought by Yong'an Hou are so special!" Not to mention the same size of each briquette, there are also many fine holes of the same size in the middle, and the concubine guesses that it is precisely because of this that the coal fire in the furnace is so vigorous! ”

Li Er was stunned for a moment, then turned his head to look at the bamboo basket, and asked while looking: "Li Zexuan, what the queen said, is there something to do~?" ”

Li Zexuan arched his hand and smiled: "Back to Your Majesty, the queen's eyes are like a torch, and indeed as the mother said, the reason why this briquette is so easy to ignite is because of its special structure!" Because this briquette resembles a honeycomb, it is called honeycomb coal! The treasure that the minister offered to His Majesty today is this coal stove and honeycomb coal~! ”

Li Er's heart sank down at this time, and he nodded and said, "Being able to make useless coal into this flammable honeycomb coal is indeed a treasure!" In this way, the imperial court may be able to consider mining a few coal mines next year~! It's just that how do you make this honeycomb coal~? ”

Seeing honeycomb coal, Li Er felt like he had seen a mountain of gold. Datang has discovered many coal mines in the Hedong Road area, but because the raw coal is difficult to burn, the mining value is not large. But now it's different!

Li Zexuan said helplessly: "Your Majesty! This honeycomb coal is made by breaking the coal, supplemented by a binder substance, and then casting it through a mold! The minister presented these two things to His Majesty today, one is to show His Majesty the advantages of combining honeycomb coal and coal stoves, and the other is to discuss one thing with His Majesty! ”

"Advantage~? What are the advantages? Could it be that this honeycomb coal is better to burn than charcoal~? ”

Li Er asked.

Li Zexuan told his wife and grandmother about the advantages of boiling water with honeycomb coal at home yesterday, and before Li Er could speak, the eldest grandson couldn't help but exclaim:

"Four pieces of honeycomb coal can boil water and cook rice all day long under full fire? Yong'an Hou, are you serious? ”

Li Zexuan nodded with a smile and said, "It's true!" And it is impossible for ordinary people to boil water and cook all day long, so the actual consumption of honeycomb coal must be even less than this! ”

"Haha! Great stuff! That's a good thing! Li Zexuan, I ask you, how much does this honeycomb coal and coal furnace cost~? ”

When Li Er heard this, he couldn't help but feel that honeycomb coal was more convenient than coal, so he laughed out loud and asked.

Li Zexuan replied: "The cost of a honeycomb coal is less than a penny! As for the coal stove, it's about one hundred and fifty yuan! But a coal stove can last at least five years! ”

Li Er nodded and said, "Not bad!" Not bad! It's cheap and practical! The people must love it! This is really a treasure for the benefit of the country and the people! Ha ha! I love it! ”

Empress Eldest Sun had a sad face and said, "Your Majesty, although honeycomb coal is cheap, not everyone can afford this coal stove!" If you want to fully promote coal stoves and honeycomb coal, I am afraid there are still many difficulties! ”

Li Er's face suddenly sank again, obviously he also agreed with what Empress Changsun said.

Li Zexuan bowed and said, "What the queen said is very true! This is also the second reason why today's ministers came to find His Majesty! ”

Li Er's eyes sank and said, "You say!" ”

"Your Majesty, now that Datang has been stable for only ten years, the price of charcoal in the east and west cities has been high, and burning charcoal is tantamount to a fantasy for the people! But in winter, the weather is cold, and in addition to boiling water and cooking, most people also need to cook a fire to keep warm! Chang'an, as the capital of the Tang Dynasty, still has many poor people freezing to death every year, not to mention other remote areas, and there will definitely be more people who freeze to death!

And now with cheaper and more resistant honeycomb coal, the price of charcoal will definitely continue to decrease! There will be more and more people who can afford to burn coal! But for ordinary people, the price of coal stoves is indeed too high, but without coal stoves, the role of honeycomb coal is extremely limited! And now in the winter, there are still many poor people who are freezing!

Therefore, honeycomb coal and coal stove must be promoted to the people together! And in order to help the people survive the winter, the minister can sell honeycomb coal and coal stoves to the poor people directly at cost price without making a penny! But the minister's strength alone is limited after all, so the minister has a small request, and I hope Your Majesty will approve it! ”

Li Zexuan said slowly with a sincere face.

When Li Er heard this, he was silent for a moment, and he said: "It's hard for you to still have this heart, I really didn't misunderstand you!" In fact, since the beginning of winter, I have been thinking about how to reduce the freezing of some people, but in Chang'an alone, there are tens of thousands or even hundreds of thousands of poor and frozen people, and the money in the treasury cannot be used now, if you have a way, please say it quickly! As long as the request is not excessive, I will grant it! ”
