The project has officially begun, the alchemy puppets have played a super high efficiency, and the casters have also shown the development power that the earth does not have, and the ground that needs to be rested has become a flat ground under the pressure of earth magic, and the places that need to be repaired are directly smashed with a destruction magic, and they can be put into use again immediately.

Zheng Yichen calculated that the entire project could be completed in about three months, and what he needed to be responsible for here only took about a week or so, and the rest of the time, just come here every few days to see the progress of the project.

After all, in addition to the construction of the subway, people in this world have not been in contact with it in the early days, and the rest of the work is basically to repetitively build tracks, as for the design of the route, Zheng Yichen has already designed it according to the map provided by the Great Wall of the border.

In addition to the construction of the subway, the framework of the train border Great Wall side of the processing is also very fast, the next day, part of it has been done, the next is the assembly work, because of the magic of this thing, after the construction of the right time can be put into use.

Therefore, it is entirely possible that the construction of the project will be carried out at the same time as it is put into use, and the starting point of these constructions is the warehouse where the materials are ready, and the trains that are already in operation are the best means of transportation, so that the efficiency is higher.

"Well, yes, the size is very good. Zheng Yichen checked the frame materials that were sent, although there were a lot, but they were covered with magic and scanned, and the specifications had already been mastered by Zheng Yichen. ”

"Do we need our help with this?" asked an engineer as he walked out.

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

After he finished speaking, he waved his hand to the side, and the alchemy puppets who had been instructed immediately divided into a team and walked over, quickly carrying the parts that needed to be assembled, the information of these parts, they all had it, and the work aspect was the same as building blocks for the alchemy puppets.

The parts that can be assembled, they will be assembled, and those that cannot, the incompatible ones 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 of the assembly, it is not a difficult thing, just to avoid some just in case, Zheng Yichen said to those engineers additionally: " By the way, you'd better set out a part of people to take care of here, after all, the alchemy puppet's adaptability is insufficient, and some minor troubles still need to be solved by humans, and alchemy puppets can't replace humans, what am I going to do? Of course, I'm going to make the core driver, otherwise what do you think I'm going to do?"

Zheng Yichen shook his head, found a place, took out a block and threw it on the ground, this square immediately unfolded into a big house, those alchemists and engineers watched Zheng Yichen walk in, the expression was like their own wife entered someone else's room, they also wanted to go in together!

Although they knew that Zheng Yichen's entry into this room was just a cover, in order to avoid being seen by some people what he was going to do, this made them even more curious, and they really wanted to go in and watch it together!

In less than five minutes, Zheng Yichen walked out and poured out the contents of the two expansion bags in his hand, which were a pair of semi-finished parts, these parts were not things like the train frame, but the core drive part.

And it's all semi-finished products, so it's going to be assembled, right?

Thinking so, the corners of their mouths couldn't help twitching, assembling is to assemble yes, but each part of these semi-finished products seems to be a little bit of that, saying that it is a semi-finished product, but this semi-finished product is too complete, the so-called assembly, just put it together like a puzzle, there is no need to do too much troublesome things!

In front of that group of people, Zheng Yichen waved his hand, and the strong magic silk thread rolled up the parts that had become products and quickly assembled them, the whole process was efficient and orderly, and those who saw it were dazzled, and when they came back to their senses, the complete core driver had been made, and the powerful engineer could see at a glance that this core driver could be perfectly embedded in the design structure of the train, and the high accuracy made them have superfluous thoughts.

"What is this furnace?, a source of mana?" asked an alchemist, looking at an open furnace above the core drive.

"Well, you can think of it as a simple magic furnace, just throw some black stone into it and keep it burning. Zheng Yichen explained that this is the otherworldly version of the steam engine...... As for whether the power is enough, what he wants to say is that the power of the otherworldly version of the magic transformation steam engine can break through the sky! The ore containing the elemental power burns incredibly high, and the amount of water vapor produced by the transpiration of the water containing the elemental power is even larger.

"Blackstone......" The engineer who asked nodded, blackstone is equivalent to a coal mine in the other world, and the place where the output is mainly concentrated in some places where the fire element hits, such as the area near the active volcano, as for why this kind of thing is not widely used, first of all, this thing is quite troublesome to ignite, and it must rely on a high enough elemental power to ignite it, and it is difficult for ordinary flames to make it burn completely, of course, after igniting a piece, it can ignite other blackstones in a row.

So basically only the caster can use this thing.,Civilians don't have the opportunity to use it.,Even if there's a lot of production.,If the caster says,There's not a lot of place to use this thing.,Keep it bright?

Besides, even in winter, they can cast magic to keep the temperature in the room to a comfortable and controllable level, instead of using blackstone to get extra temperature.

The temperature at which the black stone burns is not easy to control, it contains mottled fire elemental power, and it burns quite manicly, so even if this thing is used by the caster, there are not many places where it can be used, and civilians can just use firewood if they want to burn the fire, so the scope of application of this thing is not wide.

Now Zheng Yichen has made use of this kind of black stone, which is similar to coal.

"Can you use the flames of the black stone to drive this big guy?" Some alchemists were too suspicious of this matter, they thought that Zheng Yichen would come up with some high-power magic source, but it turned out to be a stone-burning thing, how powerful can this kind of thing be......

"This thing doesn't need to go to the sky, it just needs to run, of course. Zheng Yichen glanced at this alchemist, he was probably the kind of performance party, thinking about how to pile up the performance, without considering whether such a high performance could be used all, or even whether it could play a role.

Zheng Yichen has already taken into account the performance limit of the magic steam engine, the power of the magic steam engine is strong, even under full load operation, it can be exerted at full speed, so it is not necessary to use a high-power magic power source: "The maintenance work of the magic source is more troublesome, and there will be magic radiation after a long time, but this drive core does not have this problem, even ordinary people can maintain operation." ”

"Even when there is a shortage of fuel, releasing a fire magic directly into it can replace the use of blackstone, come, look at this. Zheng Yichen pointed to a scale on the drive core: "Pay attention here, this thing is not only to add black stone as fuel, but also to add water, the pointer must not be lower than the red area, this is very important, so you can't be negligent, don't feel troublesome, this drive core will never have any problems and reasons for lack of power, in terms of maintenance and cost, a high-power magic source can produce five drive cores, what do you think of this cost performance?"

As for water consumption, although Zheng Yichen's design has a part of re-condensing the steam into water backflow, there will still be losses......

"Also, don't think I'm cutting corners, I'm the best design, if you don't believe me...... Well, I'm able to make some additional mana-powered drive cores, and that's part of the plan. Zheng Yichen said that most of the driving core is this kind of magic steam engine, and a small part is driven by the magic source, and the magic source is driven to deal with some critical situations.

It's like a leased line.

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

"You can compare them when the time comes. ”

"Okay......" Zheng Yichen's words persuaded these alchemists and engineers, making them let go of the little prejudice in their hearts, and seriously sounded Zheng Yichen's explanation of the use of this driving core, after a while, Zheng Yichen returned to his large portable house, and it didn't take long to walk out again, this time the thing that was vacated was a large magic power source, as soon as this thing was taken out, someone immediately released the protective enchantment......

The small magic source is good to say, the magic radiation emitted is very low, just like a heat source, ordinary people can feel it, but the shadow line received is not large, unless it is a day and night contact, it will be seriously affected after decades of contact, but the one-meter radius magic power source in Zheng Yichen's place is different, even if it is a little smaller than those high-power magic power sources, but since it will be taken out, it proves that this thing is definitely capable of the work in the future.

In order to prevent accidents, of course, it is necessary to make a protective barrier to isolate it, so as to avoid accidentally being affected by the magic radiation to the body, as long as this thing is a complete magic power source, even if it is not activated, there is magic radiation emitted, it is nothing more than to look at the level of the means of isolation, if it is high, it can reduce the fluctuation of radiation very low, in general, it is not allowed to enter the living, Zheng Yichen's body is an alchemy puppet now, so others don't seem to think anything.

But that doesn't mean that others won't be okay because of this, they don't have an iron body.

"This is the driving core of the mana source, wait for me. Zheng Yichen said and quickly assembled those semi-finished parts, as for the problem of placement after assembly, isn't there still a spellcaster, there is no need for any extra coolies to do it here, just let those spellcasters come here as a crane, and those engineers can do the installation thing, Zheng Yichen positions himself as the chief boss and a supervisor, rather than working on the ground himself......

"Okay, when you compare it in the future, you will know that the performance difference in daily use is really not big. "The railroad track is two, and there will be a follow-up bifurcation later, so that the railroad track covers the border Great Wall, and even the border Great Wall has begun to plan the route according to the route designed by Zheng Yichen, as well as the related plan, and then there will be such a thing as a stop sign in many places, and the relevant staff have also started training, which is intended to be put into use immediately after the completion of Zheng Yichen's side.

After Zheng Yichen got two different types of drive cores here, the alchemy puppet had already assembled the frame parts of the train that were built on the drive core, and assembled ...... Well, it sounds a little unreliable to use on the train, but don't forget that there is alchemy magic, and the large screws and willow nails used in those joints can be treated with alchemy magic, so that they become completely integrated, and the joint places themselves have a design of mutual occlusion, in a word, under the treatment of magic, even the form of assembly rather than welding is very stable.

"Leave the skin alone, just load it on these drive cores and test them first. Zheng Yichen said that now the train is just a frame to be built on, and there are no facilities such as the shell and some seats inside, and the only thing that can be done is to be able to run...... In this way, it is enough for testing at present, the core carrying framework has been done, and the rest is basically the meaning of decoration and protection.

Test ah, after this news came out, there were immediately more people nearby, these people were all idle people in the Great Wall of the Border because the blockade was temporarily in a stable period, these people are not completely idle, they still have jobs, but they don't have much work, and they can work hard last night, and then they have a lot of free time.

Now they all came here to watch in their free time, the train without the shell was like a flatbed, plus the exposed drive core, it looked quite ugly, but the effect of this thing, as long as you are not blind, you know how important it is, so they are quite looking forward to the upcoming test.
