Chapter 545 Subtle changes


    A gust of autumn wind blew by, blowing down a few leaves and curling them around Fei Qian. For a moment, the scene became extremely deserted...


    Pang Tong glanced sideways, and then shook his head as if he hated the iron.


    "Uh...well, did I do something wrong?" Fei Qian was a little stunned.


    Pang Tong said slowly: "It''s not that I did it wrong, but that I did it right."


    Fei Qian blinked, shook his head, and said: "No matter what, I still have to say what needs to be said. Then, after I have said it, it''s time for me to leave..."


    ?Fei Qian has thought about these things for a long time, but the final decision still needs to be made clear.


    ?This is Fei Qian''s experience in dealing with people in later generations. It may be somewhat inconsistent with the habits of the Han Dynasty. The closer the relationship is between friends, the more clearly it needs to be explained.


    Just like a 50:50 two-person joint-stock company is most likely to fall into various disputes, the friendship between friends is a catalyst for promotion, and it can also easily become a poison that destroys everything.


    ?Brothers, settle accounts clearly. The clearer the account is, the longer the brother will last. Once he is confused, the brother will not last long.


    ?In the Han Dynasty, taking people away by force and then expecting the other person to suffer from Stockholm Syndrome?


    While Pang Tong, Guo Jia, Tian Feng, Zhuge Liang, etc. had not yet surrendered to others, they kidnapped and carried them away? Haha, most of the men in the Han Dynasty read the authentic works of Confucius. Repaying the direct with the direct and repaying the grievance with the grievance are the most basic understandings. Killing people with a knife is not something that only butchers do.


    Unless you are under house arrest for life, once you are given a chance...


    ?Especially for a wise and wise counselor, it is not easy to easily lead people into the ditch. Chen Gong incited the entire Yanzhou to rebel with a few words, and Jia Xu defeated the powerful Dian Wei and Cao Ang with just one sentence.


    ?Cao Cao used Xu''s mother to earn Xu Shu. Xu Shu may not have known that even if he got to Cao Ying, his mother might not live long, but in the end he chose to be worthy of his heart and his relatives, and left Liu Bei and went to Cao Ying.


    The result is not that Xu Shu did not offer advice in Cao''s camp, but that Xu Shu and Cao Cao were both smart people and understood their mutual distrust, so it was better not to say anything.


    Therefore, when Xu Shu volunteered to go to a remote area while visiting Chibi, Cao Cao was overjoyed. He immediately boasted in front of everyone, and then sent Xu Shu away at night...


    It''s not that Cao Cao really believed the rumors, nor was he happy that Xu Shu took the initiative to propose a plan, but that he had an honest reason to throw this unsightly time bomb that could explode at any time far away to the northwest border. If you send a single general, Xu Shu will be looked down upon. How can you not be happy?


    Because Fei Qian felt that Pang Tong, Zao Zhi, Xu Shu, and Tai Shiming were more or less his friends who really lived together, communicated, and clashed with each other in the Han Dynasty. If he didn''t explain it clearly, he would feel uneasy. As for whether he would like to go together after talking about it, Just rely on personal wishes.


    Otherwise, even if you use sweet words or forceful coercion, you may not be able to get the desired result in the end.


    ?Fei Qianqian cupped his hands, then turned around and left.


    Pang Tong put down the scroll in his hand and asked, "When are you going to return to Bingzhou?"


    “In two days, I still have some things to do at Huangjiayinyuan...”


    Pang Tong said oh, and then lazily started reading the book again.


    "By the way," Fei Qian said in a distant voice, "... I guess someone younger than you and smarter than you will come over some time. Remember to say hello to me..."


    Pang Tongyi was stunned, and then said "Che" very confidently, and said loudly: "If someone really comes, he will definitely greet you, but he is smarter than me... Hehehe, hum..."


    “…Believe it or not…it’s up to you…” Fei Qian waved his hand and left.


    ××××××××××××


    In the study room of Huangjiayinyuan, Fei Qian and Huang Chengyan sat opposite each other.


    ?On the table between the two people, there is a wooden box placed. The wooden box seems to be divided into many grids, and there are some things placed in each grid.


    The things Fei Qian mentioned that need to be dealt with in the Huang family are craftsmen.


    Those who make paper, cast iron, and make instruments, basically, Feiqian needs them all, and they are all urgently needed.


    ?? Huang Chengyan''s eyes lingered on the items in the wooden box, and there was an indescribable brilliance in his eyes, just like a good wine person seeing a jar of fine wine, and a lustful person seeing a beautiful woman...


    ? Huang Chengyan himself was very familiar with craftsmanship, so when Fei Qian put the wooden box he had brought during the long journey in front of him, he was attracted to it.


    Inside the wooden box are various minerals collected by Feiqian Bingzhou. The two most obvious ones are coal mines and iron ore.


    As early as the Qin Dynasty, coal had begun to enter the field of vision of the Central Plains people. However, because the original coal mines rarely contained a large amount of impurities, especially sulfur, they easily produced a large amount of black smoke after burning, which was disliked by the ancients. Therefore, charcoal is still the main method.


    Another reason why coal does not receive enough attention is that its combustion is not easy to control. It is not like adding a few firewood or charcoal to obviously control the size of the flame.


    ??But what Fei Qian now puts in the wooden box is the coal that has been roughly processed for the first time, that is, a small piece of briquettes, mixed with some clay and lime.


    This is the simplest and most convenient great invention that utilizes coal.


    The other is iron ore.


    ??There are even a small amount of copper mines in the Luliang Mountain area...


    Mica.


    Limestone.


    ?These ores filled the entire wooden box.


    For Huang Chengyan, this wooden box is even more attractive than being filled with gold and silver treasures.


    Huang Chengyan took out a small piece of briquettes and held it in his hand to look at it carefully: "Is this... pebbles?"


    People in the Han Dynasty still liked coal, especially coal essence, also called coal jade. Some people even used natural coal essence to make seals, which was basically on the same level as colored glaze.


    But for ordinary pulverized coal, not many people pay attention to it.


    “How to make this thing?” Huang Chengyan asked.


    Fei Qian said: "Crush the coal, wash it, precipitate it, take the fine powder, add yellow mud, clay, lime, and charcoal powder and squeeze it into shape..."


    Huang Chengyan called out and asked the servant to fetch a brazier. He immediately placed the small briquettes in the brazier and ignited it on the spot. Then he watched quietly, as if something was following the flames of the briquettes in his eyes. Jumping.


    Huang Chengyan said seriously: "How many people know how to make this thing...?"


    ?This kind of thing, although simple, is often ignored by people.


    For a long time, coal has been used as combustion materials in the form of cinders, briquettes, etc. Not only is it not easy to burn, but it will also produce carbon monoxide, sulfur dioxide and other substances due to incomplete combustion. .


    After adding some combustion accelerants and desulfurizers, and because the honeycomb porous structure ensures the circulation of air, the combustion will naturally be more complete, and the sulfur dioxide will also be calcified during the combustion process...


    Fei Qian said: "Huang Dou is in charge of everything related to minerals and equipment in Pingyang''s workshop... Nowadays, there are many things, and he is a little overwhelmed, and he has lost a lot of weight..."


    Huang Chengyan was stunned for a moment, then smiled and said, "Okay!"


    ah? Is it okay to lose weight? What does this mean? Doesn’t Huang Chengyan also have the potential of Zhou Bapi?


    At the entrance of Xun Lingjun’s tent...


    …


    Xun Yu: Feng...fengxiao...how come I suddenly remembered that I slept with...


    …


    Guo Jia looked around, nodded and affirmed: Wen Ruo, you really don’t have mosquitoes here... The mosquitoes are the most annoying to me when I sleep...


    …


    As a result, Guo Jijiu was sitting at the door of Xun Lingjun’s tent, looking confused...
