The project was officially started, and the alchemy puppets exerted super high efficiency. The casters also showed the development power that they did not have on the earth. Those grounds that needed rest and rest became flat under the crushing of earth magic. Where they needed repair, they directly smashed the magic to destroy them and could be put into use again immediately.

Things that cannot be done on Earth for ten or half a month can be solved in this place in just half a day. Zheng Yichen calculated that the entire project could be completed within about three months, but he only needs about a week to be responsible for it. For the rest of the time, he will come here every few days to check the progress of the project.

After all, except for the early days when people in this world have never been exposed to the subway construction, the rest of the work is basically to repetitively build tracks. As for the route design, Zheng Yichen has designed it based on the map provided by the Great Wall of the Border.

In addition to the construction of the subway, the Great Wall of the train frame was also processed very quickly. On the second day, part of it was done, and the next time it was assembled. Due to magic, tracks and other things can be put into use immediately after they are built.

Therefore, the construction of the project can be carried out while putting it into use. The starting points of these construction are all warehouses where materials are prepared. The train that can be put into operation is the best means of transportation, so the efficiency will be even higher.

"Yeah, it's good, the size is very qualified." Zheng Yichen checked the frame materials sent. Although there were a lot of them, if you covered them with magic and scan them, the specifications were already mastered by Zheng Yichen. If you don't say these specifications, the alchemist and engineer who made them obviously invested a lot of energy: "Then the next one is assembled."

"Do we need our help?" an engineer came out and asked.

"This, in order to ensure efficiency, just let those alchemy puppets do it. After all, assembly is a repetitive and tedious task." Zheng Yichen said: "Of course, you can do it if you want to join, just don't affect the production efficiency of these materials."

After saying that, he waved to the side, and the alchemy puppets who were instructed immediately divided up and walked over, quickly carrying the components that needed to be assembled. They all have the information about these components, and in terms of work, the alchemy puppets are like building blocks.

Only the parts that can be assembled will be assembled, while those that cannot be compatible will be placed aside to avoid mistakes. As Zheng Yichen said, the assembly work is tedious and repetitive. As long as you remember the parts that are assembled, it is not a difficult thing. Just to avoid some situations, Zheng Yichen said to the engineers: "By the way, you'd better separate some people to take care of them here. After all, the alchemy puppet has insufficient adaptability and needs to be solved by humans when encountering some minor troubles. The alchemy puppet cannot replace humans. What should I do? Of course, I'm going to make the core driver, otherwise what do you think I'm doing? Swimming?"

Zheng Yichen shook his head, found a place, took out a square and threw it on the ground. The square immediately expanded into a big house. The alchemists and engineers watched Zheng Yichen walk in with a gaze. The expression was like his wife entering someone else's room, and they also wanted to go in together!

Although they knew that Zheng Yichen entered this room just a cover, in order to avoid being seen by some people, this is how they became more curious and wanted to go in and watch together!

In less than five minutes, Zheng Yichen walked out and poured out the things contained in the two expansion bags in his hand. They were a pair of semi-finished parts. These parts were not things like train frames, but the core driving part. When the engineers looked at them, they actually lit up directly?

And they are all semi-finished products, so this is necessary to assemble it, right?

Thinking of this, they couldn't help but twitch the corners of their mouths. It was right to assemble them, but every part of these semi-finished products seemed a bit like a semi-finished product, but this semi-finished product was a bit too complete. The so-called assembly was just like a puzzle piece, and there was no need to do too many troublesome things at all!

In front of the group of people, Zheng Yichen waved his hand, and the strong magic thread rolled up the parts that turned into products and quickly assembled. The whole process was efficient and orderly, and the people were dazzled. When they came to their senses, the complete core driver had been made. The powerful engineers could see at a glance that this core driver could be perfectly embedded in the design structure of the train, with high accuracy that made them unable to make any unnecessary thoughts.

"What is this stove? Is it a magic source?" an alchemist asked, looking at an open stove above the core drive.

"This, you just understand it as a simple magic furnace. Just put some black stones into it to keep burning continuously." Zheng Yichen explained that this is the steam engine in another world... As for whether the power is enough? What he wants to say is that the power of the magic steam engine in another world can break through the sky!! The heat burning of the ore containing elemental power is incredibly high, and the steam generated by the water evaporation containing elemental power is even larger.

"Black Stone..." The engineer inquired nodded. Black Stone is equivalent to a coal mine in another world. The output places are mainly concentrated in places where fire elements hit, such as areas near active volcanoes. As for why this thing has not been used popularly, first of all, it is quite troublesome to ignite it. It is necessary to rely on sufficiently high elemental power to ignite it. It is difficult for ordinary flames to burn completely. Of course, after ignition of one piece, it can ignite other black stones in a series.

So basically only the casters can use this thing, and civilians have no chance to use it. Even if there are a large number of production, there are not many places for casters to use this thing, so keep the light?

The temperature emitted by this thing is so high. The winter is good, and do you want to heat yourself up in summer? Besides, even in winter, they can use magic to keep the temperature in the room constant to a comfortable and controllable level, rather than using black stone to obtain additional temperatures.

Do an experiment? The temperature of black stone burning is not easy to control. It contains the mottled fire element power, which is quite manic when burning. Therefore, even if the caster uses this thing, there are not many places to use it. Civilians just need to use firewood if they want to burn the fire, so the scope of application of this thing is not wide.

Now Zheng Yichen has used this kind of coal-like black stone.

"Can you drive this big guy with the flames burning from black stone? Is it OK?" Some alchemists were too suspicious of this matter. They thought Zheng Yichen would create some high-power magic source, but it turned out to be a stone-burning thing. How powerful can this thing be...

"This thing doesn't need to go to heaven, just run, of course." Zheng Yichen glanced at the alchemist. He was probably the kind of performance party, thinking about how to pile up the performance, without considering whether such high performance can be used, or even whether it can play its role.

The magic-modified steam engine created by Zheng Yichen has taken into account the performance limit. The magic-modified steam engine has a strong power, and it can be used at full speed even under full load operation. Therefore, there is no need to use a high-power magic source: "The maintenance work of magic source is more troublesome. After using it for a long time, magic radiation will appear. However, this driving core does not have this problem, even ordinary people can maintain operation."

"Even when fuel is lacking, releasing a fire magic directly inside can replace the use of black stone. Come and see this." Zheng Yichen pointed to a scale table on the drive core: "Note here, this thing is not only about adding black stone as fuel, but also water. The pointer must not be lower than the red area. This is very important, so you cannot be neglected. Don't think it's troublesome. This drive core will never have any problems or insufficient power. In terms of maintenance and cost, a high-power magic source can produce five drive cores. What do you think of this cost-effectiveness?"

As for water consumption, although Zheng Yichen's design contains the part that recondenses the steam into water and returns, the loss will still be...

"Also, don't think I cut corners. My design is the best. If you don't believe it... Well, I can create some additional driver cores driven by magic source, which is also within the solution." Zheng Yichen said that most of the driver cores are magic-modified steam engines, while a small part are magic source driven by magic source. Magic source drives are to deal with some critical situations. If you use the magic source drive core at that time, you will undoubtedly be able to exert faster efficiency and appear more appropriate in that situation.

It's like a dedicated line.

But the problem is that critical situations do not occur all the time.

"You can compare it then."

"Okay..." Zheng Yichen's words convinced these alchemists and engineers, and made them let go of the little prejudice in their hearts. It sounded seriously that Zheng Yichen explained the use of this driver core. After a while, Zheng Yichen returned to his large portable house and walked out soon after. This time the thing was a large magic source. As soon as this thing was taken out, someone immediately released the protective barrier...

It's okay to say that the small magic source is emitted very low, just like a heat source. Ordinary people can feel it, but the shadow received is not large. Unless it is contacted day and night, it will be seriously affected after decades of contact. However, the magic source with a radius of one meter in Zheng Yichen is different. Even if it is a little smaller than those high-power magic sources, since it will be taken out, it proves that this thing can definitely do the job in the future.

In order to prevent it, of course, a layer of protective barrier should be made to isolate it to avoid accidentally being affected by magic radiation. As long as this thing is a complete source of magic power, even if it is not activated, it will be emitted by magic radiation. It depends on the level of isolation methods. If it is high, it can reduce the fluctuations of radiation very low. Generally speaking, it is not allowed to enter a stranger. Zheng Yichen's body is an alchemy puppet now, so others don't seem to think there is anything.

But it doesn’t mean others won’t be fine because of this. They don’t have a body that is slapped.

"This is the driving core of the magic source, wait for me." Zheng Yichen said as he quickly assembled the semi-finished parts. As for the issue of assembly, there is a spellcaster. He doesn't need any extra coolies to come here to do it. He just needs to let those spellcasters come here to be cranes. Those engineers are competent for installation. Zheng Yichen positioned himself as the general boss, the supervisor, rather than working in person...

"Okay, when you compare it later, you will know that the performance difference in daily use is really not very different." The railway tracks are two, and there will be subsequent forks to cover the border Great Wall. Even the border Great Wall has started to plan the route based on the route designed by Zheng Yichen and related plans. After that, there will be station signs in many places, and relevant staff have also started training. This is planned to be put into use immediately after Zheng Yichen's completion.

After Zheng Yichen got two different types of driving cores, the alchemy puppets had assembled the train frame parts that were placed on the driving core and assembled... Well, it sounds a bit unreliable when used on the train, but don't forget that there is an alchemy magic. The large screws and willow nails used in the joints can be processed with alchemy magic to make them completely integrated, and the joints themselves have mutually ligated designs. In a word, with magic treatment, even if the assembly rather than welding is very stable.

"Don't care about the outer skin, just load it onto these drive cores and conduct the test first." Zheng Yichen said. Now the train is just a frame that is built, and there are no facilities such as the shell and some seats inside. The only thing that can be done is to run... In this way, it is enough for testing at present. The core mounting frame has been prepared, and the rest is basically the meaning of decoration and protection.

Test, after this news was released, there were more people nearby. These people were idle in the Great Wall of the border because the blockade barrier was temporarily in a stable period. These people were not completely idle and still had jobs. But they didn’t work much. If you work harder, you can quickly last night and have a lot of free time.
