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

Everyone was surprised and looked carefully and it turned out to be a poisonous stone.

Li Shimin was not afraid. He believed that Huang Suxin would not harm him. He said, "Ma Xuanliang, please dodge."

Ma Xuanliang went to the side.

Li Shimin asked: "Huang Suxin, why are you doing this?"

Huang Suxin said, "Your Majesty, this is called coal, it's a good thing!" As he said, he broke off a small piece with his fingers, put it in his mouth and took a bite, and said, "It's not poisonous, it's okay. My highness said that people's opinion is the most important thing, and they have to burn fire when they eat, and coal when they burn fire.

Recently, the wood in Chang'an City has become more and more expensive, and there are fewer and fewer trees around Chang'an City. In the future, the price of wood will become higher and higher. One day, it will be so expensive that it cannot be afforded."

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

Changsun Wuji said, "The words are good, but this poisonous stone, uh, coal, will cause poisonous smoke when it is burned. Many people are poisoned to death and cannot be used."

Everyone looked at Huang Suxin in confusion.

Feng Suxin said: "This poisonous stone, its scientific name is coal, is non-toxic. This is a treasure. The heat it produces much higher than that of wood.

As for its toxicity, it produces a gas called carbon monoxide when it is not burned sufficiently. This gas is sucked into the body and will have a toxic effect on the human body.

However, this problem is easy to solve. As long as the ventilation problem is solved, it can be used safely.

Your Majesty, dear sirs, please let me show you.”

Several eunuchs set up an iron stove with an iron pipe on it.

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

Fang Xuanling, Changsun Wuji and others subconsciously took two steps back. Li Shimin wanted to save face and stood there without moving. Ma Xuanliang hurriedly stood in front of Li Shimin to protect him.

After a while, the coal started to burn, the coal burned red and the fire was very strong. A eunuch placed a copper pot on the stove. After a short while, the water boiled.

Huang Suxin bent down, put his nose close to the fire, took a while, stood up straight, and smiled and said, "Your Majesty, please see, isn't this okay?"

Everyone began to believe what Huang Suxin said.

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

Then, the eunuchs demonstrated the use of honeycomb coal.

Huang Suxin said: "This coal is a good thing. It can not only cook and keep warm, but also smelting copper and iron. It can also be refined..."

He popularized the knowledge he learned from Li You and gave the senior leaders of the Tang Dynasty.

Li Shimin was very interested and said, "This is a good thing, but there is no such coal? Is there a lot of people in Chang'an City affordable?"

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

"There are coal mines in the Tang Dynasty, and the reserves are extremely large. Not to mention Chang'an City, even the entire Tang Dynasty is inexhaustible."

"Really?" Li Shimin became excited again.

At this time, Fang Xuanling frowned and said, "It's great to have these things, but what should the people who used to make a living by making firewood and charcoal? How do they solve their livelihood problems? Are these a large number of people?"

Li Shimin was thrown into cold water and felt a little headache. He pondered, thinking about where to allocate land to resettle these people.

Huang Suxin said: "This is not a difficult task. It also requires a large amount of manpower to develop coal mines. Among them, the coal mine itself, transportation, honeycomb coal production and other links require a large amount of manpower.

Jingzhao Yin and Guannei Road government can register people who make a living by raising firewood and burning charcoal. Anyone who is 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 many around Xianyang." Li You told Huang Suxin that the first thing he recommended were the coal mines he and Hou Junji and others bought.

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

"Your Majesty, my highness said that the court can directly auction money for money." Huang Suxin said.

"This is good, I agree." Gao Jingming said immediately.

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

My Highness means that the court issued a decree that all coal mines in the world are the property of the court. As long as the court sells the right to operate the auction, it can make a fortune. In the future, it can also collect taxes from the mine owners."

"Your Majesty, I agree." Gao Jingming was addicted to auctions. Besides, the Ministry of Revenue was too short of money.

"Wait," Changsun Wuji said: "There is another problem here. If the coal mine is on public land, the court can deal with it directly. If it is on private land, what should we do?"

This is what Huang Suxin waited for. He said: "This matter is easy to deal with. The court will compensate the landlords for the land occupied by the coal mine.

Since there are coal mines underground, the compensation should be more than twice the land price. However, this amount of money is nothing, just pay the auction of the coal mine, and the Ministry of Revenue does not need to pay a penny."

"I agree!" Gao Jingming said immediately.

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

Huang Suxin said: "This matter is simple. My Highness said, "Eat it, it will work as soon as you eat it." He said that in any place where there are coal mines, special plants will grow and can be eaten.

My Highness said that after he returns to Chang'an, he will send someone to teach the Ministry of Works how to find coal mines."

Li Shimin looked at everyone and asked, "My dear friends, what do you think?"

Fang Xuanling said: "Your Majesty, such a thing that benefits the people can increase income to the court. I think it's OK."

Changsun Wuji didn't think about it, but when he saw Gao Jingming's expectant gaze, he smiled and said, "I agree."

Cen Wenben has no objection either.

Li Shimin waved his hand and said, "Okay, let's do this. The Ministry of Revenue will be responsible for the specific implementation."

Gao Jingming was overjoyed and said excitedly: "Thank you, Your Majesty, I obey the order."

This matter was planned by Li You. Seeing that his father Li Shimin was too difficult, he wanted to increase his income to the court, solve some practical problems for the people, and make a shortcut and quick profit and spend some money.

Fu Shicheng.

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

"My minister, please see Your Highness," said Agutai.

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

"Yes, I remember it." Agutai said.

Then he asked worriedly: "Your Highness, Oh, Hamid, here is so dangerous, what are you doing?"
