Li Zexuan didn't know that Yifang County was normal, but if he talked about Lan County, he would definitely know.

In modern proven iron ore resources, Shanxi Province ranks fourth in the country with 3.546 billion tons of usable reserves and 514 million tons of unusable reserves, which does not include Shanxi-style erythrmonite that is widely distributed but has not been explored.

Among them, 89.3% of the identified iron ore resources are concentrated in Lanxian District (2 billion tons) and Wutai Mountain District (1.625 billion tons).

In addition to iron ore resources, other mineral resources in Lan County are also abundant, such as coal, iron, manganese, sulfur, marble, granite and so on! It can be said that this is a real big mining county!

And Lan County, called Yifang County during the Zhenguan period of the Tang Dynasty, was the capital of Lanzhou at this time!

Therefore, it is not unusual for Fubin to find two iron mines, two sulfur mines and a large coal mine in Yifang County!

"Thank you, young master!"

In Fubin's eyes, Li Zexuan is a real big man, and now that he can be praised by Li Zexuan, this product is suddenly so happy that he can't find the north!

"Ahem! Master! With all due respect, this coal mine is difficult to mine, and if it can mine a large amount of charcoal, it is good to say, but if there is no charcoal and it is all coal, it will be a big loss! ”

Fu Bo was obviously more stable and took a more long-term view, and he said to Li Zexuan worriedly.

"Uh... Fauber, why charcoal is useful... Oooh! I understand! But don't worry, for me, charcoal works, and so does coal! ”

When Li Zexuan just wanted to ask why charcoal was useful and coal was useless, some memories of his predecessor suddenly came out, and he hurriedly swallowed back the words that had come to his mouth, and then hurriedly said.

The memory of his predecessor told him that although people had begun to use charcoal at this time, coal had not yet become popular!

The history of coal mining in ancient China can be divided into four stages: the pre-Qin period was the discovery and early development and utilization of coal; From the Western Han Dynasty to the Northern and Southern Dynasties, coal development and utilization reached a mature stage; From the Sui and Tang dynasties to the Yuan Dynasty, it was the general development and rapid progress stage of coal development and utilization; The Ming and Qing dynasties were the heyday of coal development and utilization in ancient times.

But it should be noted that the above refers to coal, which mainly refers to charcoal, not coal, and coal was not used on a large scale at least until the Song Dynasty!

Because the untreated coal dug out of the coal mine is difficult to fully burn on the one hand, and on the other hand, a large amount of soot will come out when this coal is burned, so the common people would rather burn firewood than coal!

Because the smoke coming out of firewood is less than coal!

It was not until the late Tang Dynasty that the technology of coking with coal appeared.

According to the Tang Dynasty Kang Piao's "Drama Talks", when the noble children of Luo (Luoyang) use coal to cook rice, they must first smelt the coal to burn its smoke, which is called cooked charcoal or charcoal, and then use this charcoal to cook rice. This kind of charcoal refining is relatively close to coke, but because it is not purposefully and consciously fired, it is only the prototype of coke.

It was not until the coking technology of the Song Dynasty was perfected that China's raw coal processing and utilization entered a new stage, and the use of coal gradually became extensive. During the Ming and Qing dynasties, China's coal development and utilization had reached its peak, similar to the previous salt and iron dictatorship, and the mining rights of coal had also been nationalized, and coal mining taxes began to be levied!

"What? Does the young master have a way to use raw coal? ”

Fu Bin didn't feel anything, but Fu Bo's eyes widened, and he sat up straight from the sofa, shocked and said.

Anyone with a modicum of common sense knows what an astonishing fortune a coal mine can bring if raw coal can be used!

Li Zexuan didn't deny it, nodded happily, and said, "I know some methods!" So this coal mine must be mined! Whether it's charcoal or coal, we've got it all! ”

Fu Bo said excitedly: "If the young master really has a way to use raw coal, then of course this coal mine has to be mined!" ”

Li Zexuan smiled, he pondered for a long time, looked at Fu Bin, and asked, "Xiao Bin, you said earlier that you encountered some small twists and turns in Yifang County, what happened?" ”

Fu Bin scratched his head and replied, "Young Master, it's like this!" When we first arrived in Yifang County, we were targeted by several local ruffians! Those ruffians listened to our accents and knew that a few of us were from Chang'an, so they wanted to ask us for tolls! Biaozi couldn't get angry, so he gathered his brothers and beat up those ruffians!

Originally, this was nothing, but who knew that those ruffians had something to do with the son of the county magistrate of Yifang County, and the son of the county magistrate indiscriminately asked the officials to arrest a few of us back to prison, but fortunately, Biaozi's kung fu was much higher than those officials, so he took advantage of the chaos and escaped. Two days later, the county ordered the interrogation of several of us, which was actually just a formality.

In the public court, those ruffians have become good people, but we have become bullies who bully the weak and fear the hard, and the county magistrate and the county magistrate did not give us a chance to defend ourselves at all, and in a few words they sent us to a mine in the county to serve hard labor!

Fortunately, Biaozi came in time, and he came with the long history of the Lanzhou Thorn Mansion! It turned out that he took your warrant with your young master in the past two days to move the rescue troops to the Lanzhou Thorn History Mansion! At that time, Lanzhou Thorn Shi was not in the government, so Changshi came over!

The rest of the matter is logical, Yifang County ordered the godson to have no way, connived at his son to raise evil slaves, disturbed the peace, and was removed from his post and investigated by the Lanzhou Assassin History, and Yifang County Cheng was not spared! After the news came out, a few of us searched for ore veins in Yifang County, and we never encountered obstacles again! ”

After listening to Fubin, Li Zexuan said curiously: "Hey! Is there such a thing? This Lanzhou thorn history is not bad! Xiaobin, you have worked hard this time! ”

"Humph! Hou Ye doesn't have to sympathize with this kid! When you go out, you don't know how to change into ordinary clothes and be low-key and restrained, for fear that others won't know that you are from Chang'an City! There are so many people going to Yifang County, why don't those ruffians look for other people, but a few of you? Isn't it your own fault? ”

Fauber snorted coldly and criticized mercilessly.

Fu Bin's face was suddenly full of embarrassment, and it was obvious that Fu Bo's words had touched his sore spot.

Li Zexuan glanced at Fu Bin, and then said with a smile: "Fu Bo, you can't say that, this person was walking on the road and was suddenly knocked to the ground, can you blame the person who was knocked down for not going out today?" Xiaobin, they didn't break the law, and they didn't break the law, so they couldn't help but fight back when they were bullied by the ruffians, right?

I explained before they left, don't take the initiative to cause trouble, but don't be afraid of things! I think they did a good job this time! Besides, Xiaobin and their deeds this time, they inadvertently helped the people of Yifang County in addition to a big harm, not only no fault, but also merit! Ha ha! ”
