On the edge of the industrial area east of Cecil City, in a research room at the Institute of Machinery Manufacturing, Gowen is gathering with Rebecca and Nicholas Egg.

The round iron ball star man floated in the middle of the room. Beside him, a complex and exquisite metal model was floating with him. The metal model was obviously the chassis of the vehicle. With the high-precision processing ability of Nicholas eggs, every gear and connecting rod was restored to the most accurately, and various operation demonstrations were carried out with the magnetic field traction.

"This is the universal traction chassis after the finalization, of course, it is just a model. The specific implementation requires the efforts of technicians," said a sound from the iron ball star. While he said, he rotated the model so that Gao Wen could see the details inside it. "Based on the last design drawing, we adjusted the connection between the magic net unit and the power ridge, and added a layer of shock absorption, so that the chassis can be adapted to more complex and harsh roads. This shock absorption structure can be removed. After it is removed, it can be replaced with an additional magic net unit to make the chassis work more, so that it can be used as a tractor for construction machinery in relatively flat areas."

Gao Wen looked at the model presented by Nicholas Egg, listened to the other party's explanation, and nodded slightly: "...is not bad."

The magic car was born, and the first problem it had to face was the harsh road conditions and the difficulties in maintenance in this era.

There were no flat and solid highways in this era, and there was no service area or car repair shop in the vast wilderness between cities. Although Cecil's road construction project has never stopped since Rebecca made cement, even with the convenient means of magic, the road facilities in the southern border are currently seriously imperfect. At this stage, Cecil has only three roads that have achieved "modernization". Among them, there is a wide cement avenue from Cecil to Kant, and there is also a similar road between Cecil and Tanzania. The road leading to the Glen area was just completed a few days ago. In addition, there are basically only the messy roads built by the nobles of the southern border.

Among these messy roads, the best situation is the "temporary highway" from Tanzan to Hosman City, but that only allows the mages and engineers holding magic terminals to perform emergency leveling and reinforcement using "fossils into mud" and "sils into stone" techniques. It is OK to transport personnel and materials for the time being, but in the long run, it is not up to standard for Gao Wen from durability to scale.

As a remnant of the former separatist separatism, the "road" was a major problem that blocked Gao Wen. The nobles performed their own methods in their own territory. The roads built were diverse, not only in a mess of quality and scale, but also in a mess in the planning. Sometimes, in order to prevent the plunder of the neighboring nobles, they even specifically destroyed the areas where the roads were connected between the two territories, and used magic to shape a large number of artificial potholes, sand and mud. Now the southern border has been unified, and the former lords withdrew from the stage, but these annoying things were left to the builders of Cecil.

Fortunately, this world has incredible magic technology, and magic terminals specially used for ordinary engineers have also been popularized. With the assistance of various magic spells such as "fossils into mud", "mud into stone", and "weight loss technique", the road construction project in the southern border has progressed smoothly. However, even so, considering the actual situation in most remote areas and the situation outside the southern border, the early magic car chassis still had to consider how to deal with harsh road conditions.

"The universal chassis should pay attention to the maximum applicability, so we redesigned the size according to the average width of most roads in the southern border. Its size is basically slightly narrowed," Rebecca took the words of Nicholas Egg and gestured while saying, "The widest part is no more than 1.8 meters..."

Gao Wenxin said that it was indeed 1.8 meters tall. This is the width of the world's largest double-horse carriage. Strictly speaking, it is the limit width after two horses and a set of harnesses. Although the roads built by the nobles are diverse, their widths are roughly similar. Except for small paths and rural roads, the narrowest "official" roads will not be lower than this number. If the large double-horse carriages will be inaccessible.

The road construction of Cecil is carried out on the basis of the old roads, and the personnel and materials required for road construction must also be transported by horse-drawn carriages. Therefore, each lane of the newly built cement road is also affected by this number. Basically, the width of a large double-horse carriage plus a "safety allowance" of about one meter. On this basis, the scale of the magic car must also meet the requirements of being able to drive safely on such lanes.

As far as Gao Wen knows, similar things have happened on the earth. The original carriage width affected the standards of roads. The road standards affected the size of early cars and trains. The size of cars and trains affected the size of all things built on early roads, railway transportation, cargo boxes and other things...

Two completely different worlds finally come to the same end at this point.

Suddenly, he thought of his hometown that had been away for countless years, but Gao Wen could only sigh silently, and in his sigh, his thinking gradually spread.

With magic cars, this is an epoch-making vehicle. They are of course countless times stronger than today's carriages. With these huge and tireless vehicles, the development of the southern border will definitely take a big step forward, but if they are the only ones, it is still far from enough.

The southern border is not big, but it is definitely not small. The narrow and long territorial shape makes its east-west transportation particularly difficult. At present, in order to build four industrial new cities on the "cross axis", Gao Wen needs to allocate massive materials and personnel from all over the southern border, including ore in the Tanzan-Cecil area, wood in the Gulan area, stone and magic materials in the Pebo area, and huge immigration brought about by population migration projects. All of this is basically carried by several river transport channels centered on the Baishui River. However, river transport has natural restrictions. As the scale of several cities becomes larger and larger, especially the "cross axis" begins to extend in the east and west directions. Some raw materials far away from the river transport channel will sooner or later come on track. Gao Wen must find a way to find a more efficient means of transportation.

The advantage of magic vehicles is their flexibility and convenience, which is quite suitable for transporting short-distance and small cargoes, but their power will definitely appear to be short when dealing with the development pressure of the entire southern border.

Of course, people in this world and this era probably wouldn't think so, because magic cars are already the most advanced and powerful means of transportation they have ever seen. However, Gao Wen has seen things that are better than magic cars. Those who are galloping on the rails and can transport thousands of tons of goods at once, as powerful as the blood vessels of industrial society.

train.

Compared with that thing, the magic car in front of me will naturally appear to be dwarfed in terms of transportation capabilities.

After all, the magic car was not born to solve the transportation problem in the southern border. It is just a supplement to this aspect. Its real meaning is to start a subsequent major transformation in transportation, to replace traditional horse-drawn carriages, to manufacture agricultural machinery, construction machinery, and even prepare for military combat vehicles.

Gao Wen knew that the birth of trains on the earth was far earlier than practical cars with internal combustion engines (not the early types of locomotives with experimental nature powered by steam engines). This is because the "silly, big, thick" steam engines used by trains on the earth were far lower than those of precision, compact and efficient internal combustion engines in the technical starting point. At the same time, the various pre-technology technologies used by cars (tyres, batteries, electric spark plugs, etc.) have also undergone a relatively long period of development. All of this is determined by objective historical facts. However, in this world, the development laws of many things are destined to be different from those of the earth, and the order of many things is naturally different.

The steam engine cannot be realized, but the rotor-type magic engine emerged. In this world, a high-efficiency power source similar to an "internal combustion engine" or "electric motor" appeared in a jumping manner. At the same time, due to the technological accumulation of the world itself and Gao Wen's conscious guidance, the "magic car", a sophisticated and complex vehicle, appeared in this world earlier than the train, but this does not mean that the world does not need a train.

In fact, the South is now when it is needed, and it also has the technical foundation for researching and developing it.

After living here for so long, Gao Wen had already learned to abandon some old views and realized that the real situation hidden in this special era under the appearance of darkness and ignorance. The technological reserves of this world are much richer than he imagined, and the starting point of technology is much higher than what he saw. However, these technologies are concentrated in the hands of a few people, or are scattered in fragmented hands in the hands of scattered intellectuals (this phenomenon of "over-concentration of technology" and "technical breakdown" are the result of the collapse of the ancient Gondor Empire), which has led to the society here looking far behind its real technology.

After understanding this, Cecil's technological development speed is naturally not difficult to understand: in many cases, those technologies are not developed from scratch at all, but are mass-producing existing "upper-level" technologies, or reconstructing and transforming broken technologies. To be honest, if you copy Gao Wen's "scientific ideas" into a country like Tifeng with a strong foundation and talented talent, their development speed will only be faster than Cecil.

But even so, Gao Wen will still recognize and respect the talents and efforts of those researchers, and maintain the highest level of trust in his research departments. He knows that science is gradual. As the broken technical fragments are constantly being reconstructed, as the theories in the field of magic technology become increasingly perfect, sooner or later, this land will get rid of the shadow of the ancient Gondor Empire and enter a field that even the great magicians of the Spark Age have never been involved in.

"Ancestor?Ancestor?"

Rebecca's voice suddenly came from the side, awakening Gao Wen from his thoughts.

"What are you thinking?"

Rebecca approached Gao Wen with a look of concern and curiosity on her face.

Gao Wen realized that he had been distracted by thinking too much and just now, so he quickly coughed twice to adjust his expression, and then said while thinking: "Rebecca, do you know, the magic car is not the most powerful means of transportation on land..."

Rebecca blinked: "Are you talking about...a larger magic car?! Dragging a larger car with a multi-row linked engine?"

"...It's not quite the same. It's indeed a bigger car, but its operating mechanism is completely different from that of a magic car," Gowen organized easy-to-understand words to describe something that had never appeared in this world. "You can imagine a car with a 'magic engine' that is more than ten times, dozens of times, or even hundreds of times stronger than a magic car. This magic engine pulls more than a dozen carriages running on the ground..."

Rebecca widened her eyes: "How is that possible! The ground will collapse! And what should I do if I turn? What should I do if I encounter bumps?"

"So it needs to drive on tracks, so-called tracks are trenches or guides laid on the ground, made of steel, which can disperse the pressure brought by heavy carriages, reduce wear of metal wheels, and improve train stability..."
