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

　　

Modernly proven iron ore resources, Shanxi Province has 3.546 billion tons of usable reserves and 514 million tons of hard-to-use reserves, ranking 4th in the country, which does not include the Shanxi type which is widely distributed but has not been surveyed. Hematite.

　　

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

　　

　　 In addition to iron ore resources, Lan County is also rich in other mineral resources, such as coal, iron, manganese, sulfur, marble, granite, etc.! It can be said that this is a real mineral county!

　　

　　 And Lan County was called Yifang County during the Zhenguan Period of the Tang Dynasty, and it was the state capital of Lanzhou at this time!

　　

　　 Therefore, it is not surprising that Fubin can find two iron mines, two sulfur mines and a large coal mine in Yifang County!

　　

　　 "Thank you, Master!"

　　

　　 In the eyes of Fu Bin, Li Zexuan is a real big man. Now that he can be praised by Li Zexuan, this guy is so happy to find him!

　　

　　 "Ahem! Master! Forgive me, this coal mine is very difficult to mine. If you can extract a lot of charcoal, it's okay, but if there is no charcoal, it's all coal, then you will lose a lot!"

　　

　　Fu Bo is obviously more stable and takes a longer-term view, he said to Li Zexuan anxiously.

　　

　　 "Uh...Fubo, why is charcoal useful...oh oh! I see! But you don't need to worry, Fubo, charcoal is useful to me, and coal is also useful!"

　　

　　 When Li Zexuan just wanted to ask why charcoal is useful but coal is useless, some memories of his predecessor suddenly emerged. He quickly swallowed the words that had reached his lips, and then hurriedly said.

　　

The memory of 　　's predecessor told him that even though people had begun to use charcoal at this time, coal had not yet become popular!

　　

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

　　

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

　　

Because untreated coal excavated from coal mines is difficult to fully burn on the one hand, and on the other hand, a large amount of soot will be emitted when this kind of coal is burned, so people would rather burn firewood than burn. coal!

　　

　　Because firewood emits less smoke than coal!

　　

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

　　

According to Tang’s Kang Pian’s Records of Dramas, when the sons of Luoyang (Luoyang) magnates use coal for cooking, they must first smelt the coal to burn off the flue gas, which is called cooked charcoal or charcoal. Then use this kind of charcoal to cook rice. This kind of coking is relatively close to coke, but since it is not fired intentionally and consciously, it is only the prototype of coke.

　　

　　 Until the Song Dynasty coking technology was perfected, the processing and utilization of raw coal in our country entered a new stage, and the use of coal was gradually expanded. During the Ming and Qing Dynasties, the development and utilization of coal in my country has reached its peak. Similar to the previous dictatorship of salt and iron, coal mining rights have been nationalized, and coal taxes have begun to be collected!

　　

　　 "What? Master can use raw coal?"

　　

　　 Fubin didn't think there was anything, but Fubo glared suddenly, sat up straight from the sofa, shocked.

　　

　　 Anyone with a little bit of common sense knows what an amazing wealth that a coal mine can bring if raw coal can be used!

　　

　　 Li Zexuan did not deny it, nodded happily, and said: "I know some ways! So this coal mine must be mined! Whether it is charcoal or coal, we want it all!"

　　

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

　　

　　Li Zexuan smiled, he pondered for a long while, looked at Fubin, and asked: "Xiaobin, you said you encountered some small twists and turns in Yifang County before, what's the matter?"

　　

Fu Bin scratched his head and replied: "Master, it is like this! When we first arrived in Yifang County, we were spotted by local scorpions! Those scorpions listened to our accent and knew that we were a few of us. Those who came from Chang'an wanted to collect tolls from us! Biaozi was too angry, so he summoned his brothers to beat up the ruffians!

　　

Originally it’s nothing, but who knows that the ruffians have something to do with the son of the county magistrate of Yifang County. The son of the county magistrate indiscriminately let the servants take us back to the prison, but fortunately, the Biaozi Kungfu is better than the servants. Much higher, he ran away taking advantage of the chaos. Two days later, the county magistrate arraigned a few of us, which was actually just a cutscene.

　　

　　 In the public hall, those gangsters became good people, but we became bullies who were bullying and fearing hard work. The county magistrate and the county magistrate didn't give us the opportunity to argue at all. In a few words, we were sent to a mine in the county for hard labor!

　　

　　 Fortunately, Biaozi came in time and brought the long history from Lanzhou Governor's Mansion! It turns out that in those two days he took your young master's warrant to move soldiers to the Lanzhou Municipal Government! At that time, the governor of Lanzhou was not in the government office, so Changshi came here!

　　

　　 The following things are logical, the Yifang County magistrate has no choice but to indulge his son to raise slaves and disturb public order. He was dismissed and investigated by the provincial governor of Lanzhou. Yifang County Cheng was not spared either! After the incident broke out, the few of us searched for mineral veins in Yifang County, and we never encountered obstacles again! "

　　

　　 After listening to Fubin, UU reading www. uukanshu.com Li Zexuan said strangely: "Hey! There are still such things? This Lanzhou governor is not bad! Xiao Bin, you have worked hard this time!"

　　

"Huh! Lord Hou don't have to sympathize with this kid! I don't know if you change into ordinary clothes and low-key, for fear that others don't know that you came from Chang'an City! There are so many people going to Yifang County, why don't those scumbags find other people? Do you have to find a few of you? Didn’t you take the blame?"

　　

　　 Fu Bo snorted coldly and criticized mercilessly.

　　

　　 Fubin's face was suddenly embarrassed, and it was obvious that Fubo's words touched his pain.

　　

Li Zexuan glanced at Fu Bin, and then he laughed: "Fu Bo, you can't say that. This person was suddenly knocked to the ground while walking on the road. Can you blame the person who was knocked down shouldn't go out today? Bin, they didn't break the law or discipline, and they couldn't help but fight back when they were bullied by the ground rascals?

　　

　　 I told them before they left that they are not allowed to cause trouble, but they must not be afraid of it! I think they did very well this time! Besides, this time Xiaobin and the others accidentally helped the people of Yifang County in addition to a major harm, not only without fault, but also merit! Haha! "
