This is the first time that the young lady and the younger brother have come into contact with such a lively environment. Although they both have real dragon blood, children are children. Their mind is no different from that of ordinary Terran children. In this yuqingzong, the sister and brother are fresh in everything they see and can contact so many people. It''s like the child Ye Zan talking about the ugly words first. Although it''s easy to solve any problems in the small world of the fairy palace, it''s because he has enough control over the society of the small world through yuqingdao palace. However, ye Zan doesn''t have so much control over the problems of the small world in Shenhua domain. It may be better for Datang state to say that when it goes further and pushes public transport to other countries further away, it will be troublesome to solve the problem.


    "Please don''t worry, Shi Shuzu. I Tang will follow Shi Shuzu''s regulations and never let this matter deviate." Li Haoran quickly got up and said.


    "Well," Ye Zan nodded and said with a smile, "Haoran, you must be curious. What do I want to do for Datang this time?"


    Of course, Li Haoran was curious, but he didn''t dare to ask more. Hearing this, he scratched his head and said, "well, the disciple is really curious, but the disciple also believes that as long as it is what shishuzu wants to do, it must be an unusual event."


    "Come on, I''ll show you first." yezan said and stood up.


    As soon as Li Haoran heard that he could see it with his own eyes, he was very excited and curious, and quickly stood up.


    "Relax, don''t resist." Ye Zan said and offered the jade ball. A light included Li Haoran into the jade ball space. Of course, it is an independent space with nothing.


    Then, using the Xiangong token, ye Zan came to the small world of Xiangong again and went directly to a station.


    There are still few people in this station. After all, in such a world, people don''t need to travel far. Many people, from birth to death, may not have left the town where they live. Their lifelong needs can be met in the town. Naturally, they will not leave their hometown thousands of miles away. Only those big businessmen, perhaps really for business, or maybe they have money and want to reflect, will come to take this advanced means of transportation.


    In fact, even in the world of science and technology, in addition to intercity railways and subways, passenger transport is not the main business in long-distance railway transportation. In the early days of ancient China, that is, during the traditional Spring Festival, there was the so-called Spring Festival transportation, and the demand for passenger transport soared countless times, making it impossible to meet the adjustment of railway capacity.


    Therefore, in this small world, even in Shenhua domain, it can be predicted that passenger transport will not become the main business of the railway, and it is freight transport that really makes the railway play the greatest role.


    When he came to the station, ye Zan offered a jade ball and released Li Haoran.


    As soon as Li Haoran came out of the jade ball space, he was immediately attracted by the "special" station. You know, most of the buildings in Shenhua domain are still supported by wooden beams and columns, so they will also be limited in space. The station built by Ye Zan in the small world is a steel frame structure in terms of construction cost, maintenance and use, which looks much taller and more open.


    "Don''t look at this. It was just made to save trouble at the beginning, not the focus of this time." Ye Zan called Li Haoran and turned to the side of the station.


    Li Haoran returned to his mind. His face was a little red. He hurried up and said, "martial uncle Zu forgives sins. The disciples were also attracted by this strange building, so that they were distracted."


    Ye Zan waved his hand as he walked in front and said, "it''s okay. Don''t be so nervous. What you need to see next is what can really change the world."


    Hearing Ye Zan''s words, Li Haoran''s curiosity was immediately mentioned to the top and followed Ye Zan all the way.


    Ye Zan led Li Haoran to the platform inside the station soon. In fact, compared with the science and technology of the interstellar age, rail transit has been very backward. However, the railway system built by yezan in the small world also uses a lot of more advanced technologies, such as operation mechanism and safety measures.


    Inside the platform, there is a train of locomotives parked. Of course, this is not the original guy with black smoke, and it is not a nuclear powered locomotive, but a locomotive powered by Reiki or mana. The locomotives running in the whole traffic network, whether the specific locomotive control or the overall locomotive allocation, will be managed by artificial intelligence.


    Seeing the strange locomotive, Li Haoran was really shocked again. He didn''t know what kind of power this thing like an iron dragon would have. But soon, he saw that behind the steel dragon, goods were constantly being loaded into open or closed trunk. He is not a fool. He knows from a look at those that this thing should be used to transport goods. After all, he has never seen a locomotive or a carriage.


    However, even if he knew that the steel dragon was used to transport goods, Li Haoran was surprised by the "food intake" of the steel dragon. Standing here, watching the goods loaded into the steel dragon not far away, he couldn''t help but compare it with the traditional carriage transportation. In such a short time, the goods loaded into the steel dragon need an extremely large fleet to transport.


    As a prince, although Li Haoran practiced Taoism, he was the first to think of Quartermaster transportation. Think about the consumption of military supplies transported by Datang to the border garrison every year. It''s good that people chew horses and feed them all the way, and one third of a truck of grain can be left there. Of course, there must be some fishy things in it, but it is also true that transportation consumption is large, and there will be all kinds of accidents on the way.


    If we replace the huge transport team with the current steel dragon, even if the steel dragon does not travel faster than the carriage, the consumption in the middle will certainly be reduced a lot. Of course, there is another premise, that is, the consumption of the steel dragon should not be too terrible. If the steel dragon needs to consume a spirit stone for every trip, I''m afraid no country can afford it.


    "Shi Shuzu, I don''t know how much it costs to run this big steel guy?" Li Haoran asked Ye Zan when he thought of it.


    Ye Zan smiled and said, "you don''t have to worry about this. This... Let''s call it a dragon car. The consumption of the dragon car is certainly related to the freight volume. But in general, it can be said that a low-grade spirit stone of ordinary size is enough to run hundreds of thousands of miles."


    If we say that it is only the aura of the inferior spirit stone, of course, it is impossible for such a locomotive to really run millions of miles in one breath. However, in terms of the power of the locomotive, ye Zan uses the Juling rune. The main consumption of the inferior spirit stone is only on the activation rune.


    For the secular royal family, although the inferior spirit stone is also very precious, it is not very difficult to get it. A low-grade spirit stone of ordinary size can make the locomotive run millions of miles. Datang can still afford this consumption. What''s more, it''s not just a matter of paying but not reaping. For example, the imperial court can charge some benefits for the transportation of bulk goods by big merchants.


    Then, ye Zan took Li Haoran to a carriage in front of the locomotive, and the door on the carriage opened automatically with the arrival of the two.


    This carriage can be regarded as business class. There are not too many seats in it. There are already several people chatting there. Hearing the door open, someone turned around and saw Ye Zan who came in first. Looking at Ye Zan''s robes, the man with the appearance of a Haoshang immediately walked quickly to meet him, bowed and said, "this is the master of Yuqing Taoist palace?"


    "Yes," Ye Zan nodded and then asked, "are you the owners of those goods?"


    "Yes, we are the owner of the goods. I don''t know if the mage came, but what''s the problem with the goods?" those people stood up and looked at Ye Zan uneasily. After all, for people in this world, the mages in yuqingdao Palace are all immortal figures, so no one dare to be slighted.
