In the past, material transfer was mainly carried out domestically, and there was not much loss problem. It only took a short time to get on the track. Compared with speed, as long as the road is good, neither horses nor rivers are actually slow. The so-called loss is also That's all. But when this road extends to thousands of miles away, if you continue to use war horses, it will really kill the man to eat horse chews. Thousands of miles away, the army marches, even if the essence of heaven and earth strengthens, a hundred miles a day is not considered slow. After a hundred days of wasted supplies, Chen Xi said that I am not a god either! So it is basically doomed to get on the rail train. Although the speed may not be much improved, the train speed at the beginning is only about ten kilometers per hour. Of course, the advantage is that it can travel day and night. Of course, changing horses at the post station can also be done, but obviously It cannot be played on a large scale. Naturally, taking the rail train has become the best choice. After this change of thinking, the only thing to consider is the issue of laying tracks. In fact, there is no difference from building roads. When the roads to the Western Regions are built later, repairs along the roads will be completed. Orbital style will do. In other words, there is another big project, and we can just repair it together. Anyway, the second engine of the rail train has not been completed yet, so let¡¯s repair it first, and then we can do it after it is repaired. Sharpen the knife and chop the firewood by mistake. Work, we have reached this point, there is nothing we can do in a hurry. "It's okay to repair the track. Since you can solve the money problem, the rest is just a waste of time. It's just that this thing can't be built in a day or two." Xun Yu thought about the logistical support of thousands of miles. Line, the middleman eats the horse's chew, yes, Chen Xi is right. "Let's practice first. Since we have decided to go up here to increase our transport capacity, we should be prepared first. Then when it is time to use it, we can just get on the horse. There is not so much time to waste." Chen Xi curled his lips and said, "Mighty "Can Shuo handle it?" "I'll look for it." Liu Yan doesn't care whether it costs money or not, he just takes over the job, but I don't know if this professional still exists. It's been unused for hundreds of years, and it's not like astronomy. , Mathematics, that kind of thing that can make people feel smart when taken out, has been lost or not. "It's not a problem you're looking for, it's a problem you must find. If you can't find it, our track won't be solved." Chen Xi gave Liu Yan an order with a dark face. As for using rail tracks, save it. This dream is unrealistic. The Han Dynasty simply did not have that much iron to do this. Take China's standard railway track as an example. One meter of rail weighs almost 60 kilograms. A track of 10,000 miles, using the simplest duplex, requires a length of 40,000 miles and uses more than 1.2 million tons of iron. If Chen Xi had With so much iron, it will still be tied up on the seventh-generation ship. So to be realistic, we still have to use the wooden rails of the First Emperor. Anyway, the anti-corrosion, moth-proofing, and hardening technologies of the wooden rails during the First Emperor's era were very good. Even after being dug out for more than two thousand years, they were not completely corroded. We will continue to use the technology. Just use it. But the biggest question is, where is this technology now? This is a big question. "Okay, I will mobilize my friends to look for it for you, but this kind of technology has not been used for hundreds of years and cannot be used to show off. Zichuan, you have to be mentally prepared." Liu Yan was very worried. Helplessly explaining his difficulties, he has been hanging out with the big guys for a long time now, and he still knows what is going on and what is not going on, not to mention that many people have been secretly registered. To be honest, orbital technology like this is very confusing. "You go find it now. You won't help us here. This will be your next job." Chen Xi rolled his eyes and said. Liu Yan packed up his things and left. He really didn't deal with government affairs very much. He was really messed up in both politics and the military, but most people spoke highly of Liu Yan. Although Liu Yan can¡¯t do any serious work, Liu Yan is self-aware and knows how to brag about others. He has friends all over the world, so it doesn¡¯t matter whether he is strong or not. "Chang Wen, you can look through the treasury and see if you can find it. Since you have decided to start this thing, make preparations in advance to save yourself from being in a hurry." Chen Xi sighed and faced Chen Qun. greeted. "No, I just took inventory of the clan's treasury some time ago, and counted the old papers I got from who knows where. I still know what there is. We don't have the technology you want. We have this. The small technical family was also chopped to the ground." Chen Qun rolled his eyes and said, he would not talk nonsense in this regard. "Hey, which one?" Chen Xi asked curiously. "Xiangli clan!" Chen Qun said matter-of-factly, "This family is also good at playing tricks. Lu Buwei offended Lu Buwei when he was alive, and Li Si offended Li Si when he was in power. In the end, you know." "Oh." Chen Xi nodded and said Even though he has died to this extent, he is already a powerful Xiangli clan.?But there is no doubt that the inheritance has been broken. "Are there any other families with this?" Chen Xi asked curiously. "I don't know. If the Sima clan of Xia Yang is still there, if you ask them, they will definitely be able to give you an answer, but they are also dead." The corners of Chen Qun's mouth curled up, and he didn't know why he was laughing. Chen Xi¡¯s mouth twitched. He had no choice but to look at his face. He hoped Liu Yan¡¯s face was big enough to find what he wanted. "What do you think they were thinking back then?" Chen Xi suddenly said with some emotion. "The Xiangli family belongs to the practical group and does not understand politics. It is normal for them to bump into each other with Lu Buwei and Li Si. As for the Sima family in Xia Yang, don't you think they have too much control?" Chen Qun glanced sideways at Chen Xi and said. "If a historian doesn't write at all, writes whatever he has, and also copies the schools and directions of each school for reference, he will easily offend people." Xun Yu answered on Chen Qun's behalf, and Chen Xi finally understood. No wonder there were so many idiots later. "Anyway, a lot of things have been lost. Sooner or later I have to make a backup of the system." Chen Xi rolled his eyes and said unhappily. "Historians back then had the same idea, and then they died." Chen Qun said with a little malice, and Jia Xu and others also looked at Chen Xi. It's okay to talk about this kind of thing, but if you really want to do it, you Chen Xi One generation can suppress it, but the next generation will probably have to pay off your debt. "Okay, just kidding, how about asking them to register if they want something that is not the latest?" Chen Xi turned to look at Zhong Yao. This guy can make absolutely correct judgments at the moment. It is very good to use it when hesitating. . "It's not a problem at all. For your sake, even if you want the latest one, they will give it to you. If it's not the latest one, they will be very happy to give you a favor." Zhong Yao silently threw his plan aside. , quickly made the correct judgment. "I will send a message to that group of people later and ask them to come and register for me quickly. They have lost so many things because of the lost information. By the way, who still has chrome plating technology now?" Chen Xi glanced at those present. A group of people asked casually. It is also a metal weapon. A layer of chromium plating will make the strength higher. If there are only one or two pieces, it is an accidental coincidence at most. However, the weapons of the Qin Army in the later period were all chromium-plated, and even the arrows were also chromium-plated, which is crazy. . "Some swordsmiths still have this technology." Zhong Yao said softly. "Can it be used on a large scale? Look at the weapons of the Pre-Qin Dynasty. They are all coated with this thing to increase their strength. What about us? Can it be used?" Chen Xi said very dissatisfied. "I know someone who has this technology." Xun Yu looked sideways and said, "It's just that it hasn't been commonly used in the past few hundred years, so I've been neglected. I'll find someone to sort it out later and give you a copy. This kind of Things have not been lost, they are just used less. If you really want this kind of thing, just ask and someone will definitely give it to you. " Chen Xi said that he didn't want to talk at all. You really have it. I was just saying something casually to prove it. It has been lost, but when you look back you tell me that it is not lost, but it has become less popular in the past few years, and people don¡¯t play it much anymore. "Look, look, this is a very useful technology, but it has been left idle by you all." Chen Xi has also developed his face over the years. At least he has no problem telling lies with his eyes open. Faced with Xun Yu's answer , Chen Xi unceremoniously pretended to be dead. "Okay, don't dwell on this. If you don't want something fundamental from each company, they will definitely give you some strange things to deal with, and even give you some things that your ancestors gave up." Xun Yu was too lazy to do so. Talking about this kind of thing, who hasn¡¯t ordered a product that seeks death? "The so-called backup means two times, which is not realistic at all." "I want to hit someone!" Chen Xi said with a dark face. "It's useless. The things you can back up can only be obtained through official channels. Some things are not allowed to be spread outside." It was quite interesting to watch Chen Xi run towards his death. "Forget it, forget it, let's bring this matter to an end first." Chen Xi may have sensed Xun Yu's sincerity and knew that this matter could not be carried out, so it was a pity that he changed the subject. Then before Chen Xi could say anything, Liu Yan appeared at the Government Affairs Office with cookies. "Hey, weren't you looking for some related technology? Why did you come back so quickly?" Chen Xi said hello to Cookie first, then turned to Liu Yan and said. "I have that thing at home." Liu Yan couldn't answer, so Cookie answered first. "Uh, when did your family do this?" Chen Xi looked at Cookie suspiciously. "I haven't done it before, but my family has picked up the inheritance of the Mo family." Cookie rolled his eyes and said, "I have told you about this before. The thing you want happens to be recorded. I used to have it. I¡¯ve seen it, but I didn¡¯t feel anything about it at the time because I didn¡¯t know what it was used for.¡±
