Ma Xuanliang pointed to the black stone in Zhou Qian's hand and said, "Your Majesty, at this time, the poisonous stone is dangerous!"

Everyone was taken aback, and when they looked closely, it was indeed a poisonous stone.

Li Shimin is not afraid, he believes that Huang Suxin will not harm himself. He said, "Ma Xuanliang, you dodge." ”

Ma Xuanliang flashed to the side.

Li Shimin asked, "Huang Suxin, what are you doing with this?" ”

Huang Suxin said: "Your Majesty, this is called coal, a good thing!" As he spoke, he broke off a small piece with his fingers, put it in his mouth and took a bite, saying, "It's not poisonous, it's fine." My Royal Highness said that the people's will is the food for the sky, and if you eat, you must burn a fire, and if you burn a fire, you will burn coal.

Recently, the timber in Chang'an City is getting more and more expensive, and there are fewer and fewer trees around Chang'an City, and the price of timber will be higher and higher in the future, and one day, it will be too expensive to use. ”

His words were by no means alarmist, Chang'an City had a population of one million, huge consumption, and the growth rate of trees was unbearable.

The eldest grandson Wuji said: "The words are good, but this poisonous stone, uh, coal, will emit poisonous smoke when burned, and many people have been poisoned to death and cannot be used." ”

Everyone looked at Huang Suxin suspiciously.

Huang Suxin said: "This poison stone, its scientific name is coal, is non-toxic. It's a treasure, and it burns with much more heat than wood.

As for its toxicity, it is because when it is not fully combusted, it will produce a gas called carbon monoxide, which will have a toxic effect on the human body when it is inhaled into the body.

However, this problem is easy to solve, as long as the ventilation problem is solved, it is safe to use.

Your Majesty, ladies and gentlemen, please let your ministers demonstrate. ”

Several eunuchs set up a tin stove with a tin pipe on it.

Huang Suxin walked up to the stove, put some hay in the stove, put some broken wood on it, put coal on the broken wood, and then lit the hay.

Fang Xuanling, Eldest Sun Wuji and others all subconsciously took two steps back. Li Shimin wanted to save face, so he stood still and didn't move. Ma Xuanliang hurriedly stood in front of Li Shimin to escort him.

In a short time, the coal burned, and the coal burned red, and the fire was very strong. A eunuch placed a copper kettle on the stove. It didn't take long for the water to boil.

Huang Suxin bent down, specially put his nose close to the fire, breathed for a while, stood up straight, and said with a smile: "Your Majesty, please look, isn't the minister okay?" ”

Everyone began to believe Huang Suxin's words.

Huang Suxin pointed to a basket on the ground and said, "This is called honeycomb coal, so it's safer." ”

Next, the eunuchs demonstrated the use of honeycomb coal.

Huang Suxin said: "This coal is a good thing, not only for cooking and heating, but also for copper and iron. It is also capable of refining ...... itself."

He used the knowledge he learned from Li You to popularize the science of the high-level Datang people.

Li Shimin was very interested and said: "This is a good thing, it's just that where is this coal, how much is it, so many people in Chang'an City, can they afford it?" ”

Huang Suxin smiled: "My Royal Highness said it. Although he left the Qi Palace, he still regarded himself as a part of the Qi Palace. He said:

"There are coal mines in Datang, and the reserves are huge, not to mention Chang'an City, which is inexhaustible in the entire Datang."

"Really?" Li Shimin became excited again.

At this time, Fang Xuanling frowned and said, "It's good to have these things, but what about the people who used to make a living by collecting firewood and burning charcoal?" How can their livelihood problems be solved? That's a lot of people? ”

Li Shimin was poured with cold water and felt a little headache. He pondered, wondering where to allocate land to settle the people.

Huang Suxin said: "It's not difficult. The development of coal mines also requires a large number of manpower. Among them, the coal mine itself, transportation, production of honeycomb coal and other links require a large number of manpower.

The Kyo Zhao Yin and Kannai Provincial Governments can be asked to register the people who make a living by collecting firewood and burning charcoal. Those who are willing to engage in the coal industry will be given priority. ”

Li Shimin's eyes lit up and said, "Okay, let's do it." He continued: "Where is this coal mine, is there near Chang'an City?" ”

Huang Suxin said: "Yes, there are a lot of them near Xianyang. Li You told Huang Suxin that the first thing he recommended was the coal mines that he and Hou Junji and others bought.

Li Shimin said: "Okay, we must organize development and production immediately. ”

"Your Majesty, Your Highness said that the imperial court can directly auction to make money." Huang Suxin said.

"That's good, my lord agrees." Gao Jingming said immediately.

Huang Suxin said: "Your Majesty, it is very troublesome to develop coal mines, and the imperial court does not have so much energy and financial resources.

What my Royal Highness means is that the imperial court issued a decree that all coal mines in the world are the property of the imperial court, and as long as the imperial court auctions off the management rights, it can make a lot of money. Taxes can also be collected from mine owners in the future. ”

"Your Majesty, the minister agrees." Gao Jingming is addicted to auctions, and besides, the household department is too short of money.

"Wait," said the eldest grandson Wuji, "there is another problem here. If the coal mine is on public land, the imperial court can dispose of it directly. If it's on someone's private land, what should I do? ”

Huang Suxin was waiting for this, he said: "This matter is easy to do, the land occupied by the coal mine, the imperial court has to compensate the landlord."

Since there is a coal mine underground, the compensation should be more than twice the price of the land. However, this money is nothing, and it can be taken out of the auction money of the coal mine, and the household does not have to pay a penny. ”

"Minister's approval!" Gao Jingming said immediately.

Li Shimin asked: "How to find this coal mine?" ”

Huang Suxin said: "This matter is simple, my Royal Highness said, eat, eat it, and you will be good when you eat it." He said that wherever there are coal mines, there will be special plants that can be eaten.

My Royal Highness said that when he returned to Chang'an, he would send someone to teach the Ministry of Industry how to find coal mines. ”

Li Shimin looked at everyone and asked, "Everyone, Aiqing, what do you think?" ”

Fang Xuanling said: "Your Majesty, such a thing that benefits the people can increase the income of the imperial court, and the ministers can see it." ”

The eldest grandson Wuji didn't think about it, but when he saw Gao Jingming's expectant gaze, he smiled and said, "The minister also approves." ”

Cen text also has no opinion.

Li Shimin waved his hand and said, "Okay, let's do this thing." The Ministry of Household is responsible for the specific implementation. ”

Gao Jingming was overjoyed and said excitedly: "Your Majesty, the ministers obey the order." ”

This matter was planned by Li You, and he saw that his father Li Shimin was too difficult, so he wanted to increase some income for the imperial court, solve some practical problems for the people, and by the way, make a short time and make some money to spend.

Fu Qi City.

After Li You and the others entered the city, Agutai arranged their accommodation, and then came to meet Hamid alone.

"Minister, Agutai, see His Royal Highness the Prince." Agutai saluted.

"No courtesy. Remember, my identity must be kept strictly confidential. Hamid said.

"Yes, I remember." Agutai said.

Then, worriedly, he asked, "Your Highness, oh Hamid, what are you doing here, this is so dangerous?" ”
