In fact, the Chinese already knew how to use coal as fuel as early as the Western Han Dynasty 2,000 years ago, but because of the limitations of transportation and mining technology, it was far less easy than straw and charcoal, and only some people used it in some areas with shallow coal seams. It was not until the end of the Tang Dynasty that people gradually paid attention to its advantages of high temperature and high efficiency, and it was only in the early Song Dynasty that coal was applied to the smelting industry on a large scale, which raised China's smelting technology to a higher level.

The Guanzhong area contains abundant coal resources under the surface, but it is not known to the world due to its deep burial. After listening to my description, Lanling became very interested in this magical ore that can be easily smelted, and Tongguan (Tongchuan) is only a short distance of more than 100 miles away from Chang'an, the center of science and technology and trade in the world today, and once it is successfully mined, the consequences are unimaginable.

"Is it good to bully the illiterate?" Lanling read to me classical Chinese, which is still the classical Chinese of the Tang Dynasty. It's too much of a bully, it's too much of a nobody! "Now that you've found it, dig it. As for how to dig and how to turn iron into copper, I don't understand, you can figure it out for yourself later. "It's true, although I often went to the steel mill to pick up some briquettes and iron slag when I was a child, I never went into the operation room once, and I assured Chairman Mao!

Lan Ling stared at me seriously for a while and smiled. "It's true. The hairy boy with fine skin and tender meat, no matter how good he can be a blacksmith, has not become a fairy. Dig some back first, and push the coal car to the Ministry of Engineering, and I won't care. He took off his shoes, leaned back on the soft chair, and smiled, "Do you think the officials of the Ministry of Industry will scold us behind our backs?" ”

Oh, my God! The ancients were too gossipy, could it be that Lanling and I have already made trouble in the city? "Huh? Our business has been ...... Even the people in the Ministry of Industry know about it? "It doesn't make sense, although Lanling comes over every day, but it's all under the guise of Heying's talented sisterhood, I haven't been to Lanling's house once, why is there such a rumor? Could it be the two maids in the back house?

"Die!" Lanling smashed half of the dim sum in his hand, and I calmly turned my head away and didn't hit it. "Hide faster than anyone else!" As he spoke, he grabbed a snack from the table and pretended to throw it, "I'm scared to death, it's not worth a snack yet." I mean, let's give the Ministry of Workers a hard time to find trouble; First of all, your fire yao, it blew up again yesterday, but fortunately, no one died; Pull the coal away, but I'm afraid that I will have to turn it on my back. If people don't scold the two of us, who will scold? ”

"It's all the trouble you're looking for, oh, and Old Man Cheng. Scolding you two goes, what's the matter with me? The stone fell to the ground, and the mood suddenly became much more relaxed, "It's all good, I said you can remember." I just want to get to the bottom of it, and get things to harm others, and I am entangled in them. ”

"I haven't succeeded yet, so I think I'm numb?" Lan Ling picked his eyes and said softly: "What are you afraid of, are there any rumors in the capital?" Recently, there have been rumors about me and Cheng Chu's gossip, and the head of the story is the Tao, but I don't know how it was arranged. These people, my ears are calloused, didn't you think I was that kind of person before? He passed on his, who is a little famous and has no gossip on his back, and he has long been taken seriously. Are you still innocent? ”

"What's wrong with me? Got into trouble too? "Cheng Chu and Lanling's gossip can be understood, it must be Cheng Chu spreading admiration for Lanling everywhere, and it is strange if he can't afford rumors. But who did I recruit to provoke whom, one day the door is not out, the second door is not stepped, more than a girl, what gossip can I recruit? "I don't believe it, who has someone as honest as me, who doesn't even enter the city a few times, what right and wrong can come out?"

"Are you honest? God really opened his eyes. Is there an honest man who doesn't even let go of the widow princess? Lan Ling raised his eyelids and glanced at him ambiguously, "The love between you and Cui Zhang, now Chang'an is a good story." Other people's rumors are still looming, and things are not; The two of you are in the hall with eyebrows and affection, and you have seen more than one or two, and you can't escape. It seems that the fate of the two little marquis is not shallow. Zihao is quite discerning, to say that there are not one or two people who are full of Chang'an's ideas to fight the world, so that you have a head start. Lanling said proudly, sighed loudly, laughed indiscriminately, and looked like he was underbeaten.

Oh, my God! Isn't it just the boredom of queuing up on the day he sent Zhuang Ding to join the army, making a joke with his eyes! Who preached such a lack of virtue? It seems that there were many gentlemen in the queue that day, and they were arrested. No wonder I only saw the Cui family's gift recently, and I didn't ask me out to play again, it is estimated that Cui Zhang is more depressed than me now. I am now more wronged than the goose of the Dou family (Yanda quotations), not to mention jumping the Yellow River, even jumping sulfuric acid can't be washed. It was so disgusting that he raised his arms and shouted: "Wronged! "How can I say that he is also a celebrity now, and when people in later generations mention the inventor of Huoyao, while admiring and admiring, will they investigate the special sexual orientation of this great scientist? I'm too scared, I'm so embarrassed, I'm too wronged, I'm too ...... "What has it been like now?" ”

"I didn't say anything, anyway, everyone knows the name, and I won't say it if I'm tired of it." Lan Ling smiled evilly, with a wicked smile, "But now many people are discussing the inside story of Qin Yu and Cheng Chufang's comfortable life in the Guogong Mansion, but they are running into the army. It seems to be related to you, a talented teacher, what kind of coercion and coercion, the two students are unbearable, and they would rather go to the army than go back to Chang'an and so on. ”

Don't let people live, huh? It's just that the demon is here, and it is rumored that the dragon yang mad demon will let me see people! said with a bitter face: "It's not that you don't know the reason why they joined the army, and you can't go out!" ”

Lan Ling nodded, with a look of pity, "Of course I know, and I know that you don't have such weird habits. But others don't know, can't I jump out and explain? ”

"Then I'm done? Carry the reputation of Longyang for a lifetime until you kick your legs? Thinking that he was going to spend his life miserable in other people's spittle, it was better to die, "If I can't live, I want to strangle myself to death, it's too disgusting." ”

"Haha....." Lan Ling's feet kicked happily, "You are reluctant to die." You must know how many people in the capital are envious to death, and they ....... Cui, Cheng, and Qin at once. ”

"Make you laugh, make you gloat!" stepped forward and turned over Lanling and pumped her buttocks, "Not to mention helping to refute rumors, I'm still happy to be like this, it's too much!" ”

Lan Ling smiled to herself, and let me hit me a few times, without interference, "Do you know the suffering of the concubine?" Seeing that I was done fighting, he turned over and had peace in his eyes, "The mouth is long on people's faces, can you fight one by one?" The more cautious and cautious you are, the more filthy the words will become, and I'll not come here too? The gossip that spread about me back then was amazing, and you are like this, will you not live in the future? ”

"I also know that you are right, but you are still weird in your heart." Nest a belly of fire, took a brush in his hand, and made a hard effort, the quality is good, no folding, "Listening to other people's gossip is a pastime, now it's your turn, it's not a taste, and the gas can't come smoothly for a while, there is fire." ”

"You are the stove fire, and the effort of a meal will be extinguished. I know you best, and I'm grinning, it's good to pass this point. Lan Ling didn't care, sat up, "You haven't run to the military headquarters in recent days?" ”

"No, I've taken care of the food, and I'm too busy to get out." Since I got the military report that the soldiers of the Third Route Army were coming to Pyongyang, I haven't gone to the military headquarters too much. Nowadays, in the world, there is no city that Su Dingfang, Xue Rengui, and Liu Renliang, the three super thugs, can't lead the role, not in Asia, and not in Europe. The combined power of these three people is no less than a nuclear storm, plus the director Du Feng, who is yin and lacks morality, planned it single-handedly; Pray for the enemy, I can only ask them to be free and comfortable, and not to drag the mud and water to suffer. "It is estimated that the Korean people will not even have the strength to hold a knife, Du Shangshu is too inhuman!"
