"Can't sleep, can't sleep, good guy, this thing is so strong, I almost passed out all of a sudden."

I have to say that the effect of this sleeping pod is really good, just lay down and set the temperature and humidity, feel the wrapping feeling brought by the soft and comfortable mattress, and feel the unprecedented relaxation of the neck, Lin Yue almost fell into a coma.

"No, I'll have to get it in the bedroom, where can I sleep with this place?" Lin Yue pressed the button at hand, and soon the door of the space sleep capsule opened.

And before Lin Yue could jump off, he found that next to the sleeping cabin were two pairs of extremely curious big eyes.

"You want to come in and try it too? But it seems that the size is not good at all haha. Lin Yue patted the two little guys who were next to him, and they seemed to be extremely interested in the space sleep capsule.

Even if you drag the "sick body" to satisfy your curiosity, you want to come to the side to take a closer look, what kind of spirit is this?

Discover the spirit of intellectual curiosity!

"Okay, okay, I'll put it away first, and when it's okay, I'll make a design for it, and see if I can design it for the two of you to enjoy this good thing."

For this space sleep capsule, Lin Yue has already given it a five-star praise after experiencing it, which is really good.

It would be better if Xiaobai and Xiaomeng could also sleep on it.

However, Lin Yue also noticed that many of its devices seemed to be quite complex, and even contained a miniature computer in them, and if you wanted to replicate it, you might need to find a fairly suitable chip.

"The Legend of the Fairy Tree"

Of course, this mattress also seems to have to find a wave from the secret realm, and there is no corresponding thing in the other world, even if those thick wools are not bad, but they are thousands of miles away.

"Okay, the next thing to look at is the last one obtained, which is this 'short and medium-distance track-type fast train and track design drawing'."

Lin Yue put away the space sleep capsule and took out the last thing in the treasure chest.

The appearance of the blue drawings is no different from other design drawings.

But the name of this design made him very excited!

Designs for short- and medium-distance track-type rapid trains and tracks!

In fact, to put it simply, it is the design of the train and the tracks!

[Design drawing of short and medium distance track type fast train and track: It can be established at the short and medium distance (within 100 kilometers) between two points of the track, the platform and the fast train running above the track, the train speed can be adjusted according to needs, the default uniform speed is 110km/h, driven and stopped by electricity and fuel, and the service life is 10 years! 】

"If there are enough materials, then, I can build a high-speed passage between the shelter and the shelter!"

The railway is one of mankind's greatest inventions.

It can almost be said that to a certain extent, it has promoted the course of civilization on the modern earth!

Railways connect cities and cities, and while constantly transporting goods, they also drive the economy, greatly promoting the circulation of goods, and also promoting exchanges between regions, and making the flow of bulk resources no longer require a lot of costs as in the past.

Trains have also evolved from steam trains to fuel trains, trams, and even maglev trains.

From carrying goods, carrying people to transporting important weapons, etc., trains also have a pivotal position!

It can be said that without the invention of trains and railways, perhaps the advancement of human civilization would have been much slower than before!

Now, in this other world.

All of humanity was teleported here, more than seven billion people, and in the end, after five catastrophes, only two billion people remained.

Two billion people, on the land of an unknown otherworld, have established millions, if not tens of millions, of shelter villages.

There is a vast and unknown area between the evacuation villages, and the connection between them is limited to the group function of the system or the chat function of the world channel.

It seems that the various modes of transportation on the modern earth have never appeared in this barren and barren wasteland world.

After the human beings came to this other world, all the ready-made conveniences that they originally enjoyed were gone, and all kinds of equipment that could make construction machinery and various industrial products naturally disappeared.

Due to the lack of materials, resources, and even knowledge, human beings are unable to reproduce the various convenient means of transportation and the construction of basic roads and railways in the past.

In the end, we can only rely on the original traditional method from ancient times - walking to and fro.

Whether hunting or gathering resources, humans have to rely on their legs to achieve the purpose of moving.

There is no way, or rather, there is no way.

After all, whether it is a road or a railway, not to mention how many resources and materials are consumed to make it, just "how to do it" is a problem.

Even if you go to the secret realm and go to great lengths to carry those scrapped cars, bicycles, trains, etc., back here, you can only slowly put them into the dust.

Just like himself, when he first drove the off-road bicycle and the ordinary bicycle, he was indeed happy for a while, but soon because there were no roads, they were useless.

The off-road bike rides on this bumpy, uneven wasteland, and it takes less than a minute to ride three or four times, and it is better to walk.

It wasn't until later that he found the car from the secret realm, then found the ATV, and finally used the high-precision research workbench to break it down into blueprints and parts, and finally built the only car that could be driven in this other world.

At the same time, he continued to collect asphalt pavement, and used a workbench to break it down into blueprints, and successfully built the world's first road.

And the road, which has now managed to extend from this main refuge, through the vast wasteland, to Lake Berg, and from there to the east, to the saltpeter mines beyond!

This distance is almost nearly 100 kilometers, and even if it is a little white, it will take nearly an hour of long-distance flight and consume a lot of physical strength.

It's pretty much the same with driving, you have to waste an hour here, and you have to make sure you don't encounter any mutated creatures in the process.

Otherwise, it will need to be delayed for a longer time.

Moreover, the road is built almost on the surface of the wasteland, making it easy for mutated creatures to pass through.

If you are driving forward, a mutant sheep will rush out of front of you at a very fast speed......

It must have been quite a tragic accident!

Fortunately, until now, Lin Yue has never encountered such a thing, but it doesn't mean that he won't encounter it in the future.

Ordinary fences can't stop mutated creatures that are everywhere and have a strong desire to attack, and maybe one day he'll encounter something like this while driving.

At that time, if any accident happens because of this, it will really outweigh the losses!

Lin Yue didn't want to encounter that kind of thing.

Now, with the arrival of this "short and medium-distance track express train and track design", there is no doubt that his means of transportation will be further increased, and it will also allow him to quickly travel to the sub-base of saltpeter mines and oil rivers!

Short-term movement will also make the mining and collection of resources more efficient, and it will also allow him to improve his living standard to a higher level!

"Who doesn't want to get to their destination by sitting and lying down?"

Lin Yue knew that if the materials were sufficient, then he would soon build a proprietary railway in this other world!

"I'll see what is needed...... Naturally, the rails need steel, and there are still some of them, and there are quite a few of them, and there are a lot of leftovers from the last time I demolished the Tokyo Tower, and there are also a lot of wood, and gravel can be made of stone......

There aren't many types of materials needed for a short section of track, carbon steel, wood, stone, and of course, if you want to lay a whole section of track, it seems that you need some wires.

There's just one problem that needs to be addressed.

This other world is not as peaceful as the earth.

There are not many mutated creatures here, and the number of them is simply amazing.

If they make the orbit their place of residence and thus occupy it, then he will face an endless expulsion of the mutated creatures.

This kind of thing will greatly occupy his time that is not enough, so that this convenient thing will become a burden and a burden.

So, if you want to build this thing, you have to think about a way to not be attacked, overtaken, and harassed by mutated creatures.

"Viaduct!"

Lin Yue thought of this solution to all the problems almost instantly!

That's right, if there is a viaduct, then everything can be solved!

Originally, on the earth, railway tracks were also set up with viaducts, and even in the era of high-speed rail, viaducts even became the main means of laying.

Viaducts are a very convenient and useful means of passing through complex terrain, residential areas, rivers, mountains, etc., allowing the track to be laid forward and the train to compensate for the terrain difficulties caused by the height difference.

And in the other world, viaducts with a height of more than ten meters or even higher will also become an existence that those mutated creatures cannot shake.

If there are shortcomings, there are also disadvantages.

The first is the disaster, which is completely impossible to avoid, and can only be guaranteed by reinforcement and preparedness.

The second is the giant creatures, although the giant creatures in this vicinity have been wiped out by him, but he is not sure when, the lizardmen will drag them to appear from unknown places.

If it's a giant creature, it can do some damage to the railway.

emmmm…… There's no other way?

After thinking about it for a long time, Lin Yue found that it is true that all kinds of methods have shortcomings in various methods, but if they hesitate so much, then they really can't move forward in one step.

However, it's late today, it's time to go up and rest, and you can't stay here all the time, the treasure chests are all open, aren't they?

Xiaobai and Xiaomeng are still looking around the mineral resource reserve detector at the moment, and they still seem to be very curious.

In other words, the two of them seem to have opened so many treasure chests, and they don't look bored at all.

Especially Xiaobai, how many times have you been in a row, why have you always been curious?

"Okay, let's go up, it's nothing, you two can really wait."

Lin Yue took a deep breath.

He looked at the palladium chest that was still there.

Under the light, it still glows all over, and as a special bonus, it doesn't disappear when it's turned on.

"This thing...... It's a treasure, right? Lin Yue stroked this huge palladium treasure chest, its weight was not at all something he could handle, the treasure chest of the system was actually very realistic, real and should have the thickness.

The treasure chest that will not disappear, for Lin Yue, its only function is to be beautiful.

But it is beautiful and can't be eaten, in his eyes, such a big thing is placed here, just to occupy a place.

Moreover, Lin Yue is still a little concerned.

The main material of the palladium treasure chest is "palladium", you know, this thing is ridiculously expensive on earth.

The main reason why it is expensive is not because of hype or anything, but because it is indeed very rare and rare, and it is quite difficult to mine and smelt.

Palladium is a metal with excellent physical and chemical properties, high temperature resistance, corrosion resistance, wear resistance and strong stretchability.

It is also an indispensable key material for high-tech fields such as aerospace, aviation, navigation, weapons and nuclear energy, as well as the automobile manufacturing industry!

This...... Of course, it was what the systematic appraisal just told him.

The palladium treasure chest in front of you must be hundreds of catties larger, if all of them become palladium nuggets of equivalent units, then ...... Looks like this thing is more valuable than the ones in the box!

"So, it seems more correct to do without delay?" Lin Yue took out the high-precision research workbench and touched it to this palladium treasure chest!

"Break down into raw materials!"

Lin Yue didn't hesitate, who wants the design of the palladium treasure chest.

【You have obtained Palladium X8!】

The treasure chest in front of Lin Yue quickly disappeared, and the eight pieces were only twenty centimeters long, and the silver-white cube appeared instantly!

Palladium in hand!

It's not just a nice decoration, it's sure to be useful in a lot of places!

Aerospace!

Although nothing related to these two has been opened until now, Lin Yue feels that when it can be opened one day, then palladium will also be useful.

Moreover, the palladium on hand will not be limited to this point forever.

Looking at Xiaomeng's injury, his foot was already swollen, although there was no fracture or anything else, but it was impossible to pick up Xiaobai again.

Xiaobai himself can't go up directly......

It seems that these two poor little guys can really only rest in this unboxing area.

Lin Yue took out a few thick sheepskins and spread them on the ground, letting Xiao Bai and Xiao Meng occupy three on one side, and put enough water and food on the side.

"You two, you can only rest here for the night, tomorrow I want to find a way to pick you up again, both of you stay here obediently, do you hear?"

I wanted them to go up, but I had to do what I could.

Let's see how their injuries will be tomorrow.

After spraying each of them with white medicine and pasting the plaster, Lin Yue went upstairs directly and walked towards his bedroom.

And the two little guys, with a mood that has not yet changed from excitement and excitement, slowly closed their eyes.

……

Somewhere, underground ruins.

A huge army is being assembled!
