First of all, Xiao Chen had to have an idea of how strong he was in building a teleportation array, and Xiao Chen naturally wanted to build a teleportation array that was as solid as possible.

And he himself didn't know much about the teleportation array, and Hera probably knew much more about it.

But Hera should still be resting now, and Xiao Chen didn't want to disturb her, so she had to return to her room with the blueprints of the Dark City and the Blueprints of the Star City.

said that it was his own room, but it was actually shared by Hera and Xiao Chen, after all, they looked like a couple, so when arranging the room, the person who arranged the room had a look that I understood, and Xiao Chen didn't deliberately mention anything to live separately, and he was not stupid.

Creeping back to the room, Hera was still asleep, Xiao Chen smiled slightly, walked to the table with his extraordinary night vision, and took out a small sun stone from the table drawer and put it on the small table on the table.

This is something that ordinary hotels in the dark city will supply, Xiao Chen is already extremely familiar with the Sun Stone, after all, it is a product of Star City, so it is naturally handy to use. Sunstone could have also been used as a small light source that would emit a soft light without consuming much energy.

Xiao Chen spread the drawings of the two cities on the table, carefully examined the drawings, and then pondered where to build the teleportation array.

Before you know it, a few hours have passed.

"Hmm, little brother, how long have I been asleep?" Hera is still used to being called Brother Xiao Chen, which can bring some first-time feelings.

Hera rubbed her misty eyes, picked up the glass of water on the table, and took a few sips.

"There's no concept of time here, so if you're sleepy, just keep sleeping." Xiao Chen smiled slightly and continued to look at the drawings.

"Hmm~" Hera stretched lazily and paced behind Xiao Chen, her face slowly approached Xiao Chen's shoulder, and she looked at the two drawings curiously, "Little brother, what are you looking at?" ”

The demons' night vision ability is very good, although Xiao Chen is not a 100% demon, but at least he is half a demon, so this ability is not bad.

"These two are the blueprints of Dark City and Star City, I want to choose a place to build a teleportation array." Xiao Chen said, "By the way, Hera, do you know anything about teleportation?" ”

"Uh, what's the teleportation array......" Hera touched her head, looking confused.

"Uh...... It's the red ball that can often be seen at the Infinity Border, which is the smallest, and the Cross Gate. Xiao Chen said.

"Hmm...... The words of the Cross Gate, which seem to have been left behind by those who drove huge warships from very old times, should be some kind of high-tech product. Hera thought carefully, "The words of those red balls seem to have been left behind by the founder of the world. ”

Xiao Chen's heart moved, the founder of the world, that is to say, it has something to do with those ancient relics, and the divine crystal he obtained should be able to help, as for the high-tech portal cross door...... You should be able to do it through the Holy Spirit system.

The powerhouse of the original star, it is not difficult to create a teleportation channel, but the difficulty is to maintain the stability of this channel.

The teleportation array is the teleportation channel after solidification.

I have to say that the Holy Spirit is a very buggy thing, and one of its functions is to open up spatial channels according to its own memories and thoughts, and if it is controlled by a guy like Olihus, it can even open up a channel beyond the world.

And what Xiao Chen has to do is only a spatial transfer within the same world, so it is even simpler.

Xiao Chen already had a general idea of what to do, after all, there was also a precedent for building a successful large-scale teleportation device in the shadow mirror, so he only needed to analyze the Holy Spirit system.

In fact, the stars also created a teleportation device, Xiao Chen's teleportation is an example, but the energy consumed by that device is too much, and it is enough to use half of the warehouse's Sun Stone Crystal Stone. The Sun Stone Crystal Stone is a kind of energy aggregate that contains more pure energy than the Sun Stone, and even if the stars want to extract this kind of extraction, it will be used up by Xiao Chen's teleportation for most of it at one time.

You must know that Xiao Chen's first teleportation took several days, so it was normal to consume so much energy.

And the second return of Xiao Chen, that is the spatial jump point opened up by the Black Rider King, which belongs to the situation of copying shortcuts, and finds the overlap between the original realm and that world, so as long as you open up a short space jump hole, you can reach it, and Xiao Chen's first astral teleportation is really too far away.

Xiao Chen naturally couldn't use that strange technique to build a teleportation channel, and the amount of sunstone crystal stones used to teleport one and a half warehouses was too exaggerated.

Xiao Chen studied the teleportation method used by the deity before and figured out the principle. The deity's astral teleportation method is to maintain the stability of the channel by providing energy through the Sunstone Crystal Stone while constructing the teleportation path, and a considerable part of the energy is used to open up the space pathway.

And the pioneering part of Xiao Chen can be completed by using the Holy Spirit System, which avoids a large part of the energy loss, and the rest is to maintain the spatial passage.

If the Holy Spirit system is used, it is actually possible to partially alienate the spatial structure and stabilize the spatial structure, but in this way, it is necessary to construct several spatial nodes.

The Holy Spirit System is equivalent to an artifact-level chisel, with the ability to chisel through space, and space is equivalent to forcibly opening a path, because of the chaos and expansion of space, so there is often a mess of space storms.

Therefore, the structure of the space is generally very unstable, and Xiao Chen must use the chisel of the Holy Spirit to constantly excavate and modify until he can open a strong enough and stable enough passage to come out.

Obviously, the workload of doing this is very huge, only one passage is fine, if you want to establish more passages, it is estimated that Xiao Chen will have to build a teleportation array here in the past few years, so this is the next step, Xiao Chen will use this method when there is really no way.

Xiao Chen rubbed his swollen brows, in fact, space construction is more suitable for handing over to the deity, relying on the computing speed of the brain that has exploded the brain, it is a matter of minutes to build a model, and with his hands-on ability, he can also ensure that the teleportation array is flawless.

So, is there any other way?

Xiao Chen frantically searched for all the theories related to space theory that he had seen before, and suddenly, Xiao Chen patted his head and almost forgot about this.

That's right, it's the theory of spatial folding.

This is a widely used and well-proven theory, and it is the world overlapping theory that the Black Rider used to open up the world void before.

Legendary-level powerhouses are already able to judge spatial nodes and construct small dark tunnels for world teleportation, such as the Black Rider, who roams between worlds everywhere, and is even more experienced, and can see at a glance which spatial node will be connected to what world.

Therefore, it will be very troublesome to fight with this kind of guy, and a strong person who is familiar with the characteristics of space can escape anytime and anywhere, as long as he attacks the node in the opposite direction, he can destroy this spatial passage in a short time, so it is almost impossible for the opponent to pursue himself through this method.

No matter how fast the opponent's speed is, as long as you leave the spatial passage before him and attack the node, then it is impossible for him to catch up with you in a short time.

Because once the spatial passage is destroyed, the people who stay in the spatial passage will face a spatial storm that will sweep everything around, and it is simply impossible to find a usable node to go out again in this state. It's like two sides of a cube, and two sides are two worlds.

The shortest distance to the opposite world is to open the node in front of you, the shorter the distance between the two sides, the shorter the protrusion time, when the node collapses, the person falls to the inside of the cube, which is full of various spatial substances. Even if you are only a line away from the person who has fled to another world, then when you fall into the storm space, this line of distance will become unknown how long, you can only find a node to go out when the nearby space storm gradually stops, and you are not sure that this will be the shortest node to the other world, it may appear that you are not far away from the other world when you are not aware of it, of course, it is more likely that the other party has run to other worlds.

And BT-level guys like William and Verrus, their control and familiarity with space have reached the extreme, because they are chaotic creatures that have been associated with the universe since the beginning of the universe, also known as immortal creatures, so they have no such worries at all.

First, because they are completely unaffected in the space storm, they can easily find the shortest node to reach the other world, and they can even go to other nodes to contain others in advance. The two of them have experienced countless plane transfers in an endless amount of time, so they know far more shortcuts than ordinary legendary powerhouses, they can simply publish a book, this road is broken, they can take another way, and even when they see the opponent's move, they know what way the other party is going to take, they can take another way to intercept him, and they will not do the stupid thing of squeezing a space channel with the other party at all, of course, even if they squeeze it, it will not affect at all, they have a way.

Now, then, it is the theory of the spatial folding of the world that needs to be applied.

This theory is very interesting, roughly meaning that the two sides of the transmission are two points, as long as you can find the point between the two points, and then collude with the point between the two points, and connect the two destinations through that node, you can create a strong connection.

Through this connection, it is possible to get from Destination 1 to Destination 2 in an instant.

This contradiction sounds very contradictory and complicated at first glance, so when it was first proposed, it was also questioned a lot, and many people did not understand what this theory meant.

Xiao Chen also studied for a long time and listened to the Buddha's explanation before he understood, first of all, he had to know that the world space was not flat, so the midpoint between the two points could be in the land, or it could be in the ocean, anyway, it would be in all kinds of strange places.

Opening a spatial pathway to the middle point at destination 1, and then opening a passage from the spatial point to destination 2, will create a strong connection with the two destinations in this compromise.

However, it is possible that the connection between the two destinations and the midpoint is not in a straight line, so don't be surprised, because the judgment of the midpoint is not measured by the physical view of reality, but by the view of the universe and space, that is, the basis of judgment is different.

Through this transit connection, the two sides can resonate, which in turn can lead to teleportation.

The most powerful part of this teleportation is that it is not a displacement over a spatial distance, but a mapping, which is really just a point-to-point mapping. And that so-called midpoint, which is equivalent to a common glass, only acts as a link between the virtual image and the entity, so this kind of teleportation basically does not take much time, and it is completed in the blink of an eye.

If this theory is used, then Xiao Chen only needs to solidify the intermediate node between the two destinations, which will greatly reduce the workload.

Xiao Chen was very excited at the moment, and he had finally overcome the difficulty of building a teleportation array.

Then, the next problem is the construction of the space node and the construction of the two-way teleportation array. The legendary powerhouse can make this kind of leap because the legendary powerhouse itself has strong energy, so during the transfer process, the node will absorb the energy of the legendary powerhouse to complete the transfer.

Obviously, the teleportation array needs an energy source to provide energy, and the construction between the two teleportation points must conform to the principle of mapping.

The point-to-point mapping teleportation mentioned above is only a relatively primitive method, and although it can be achieved, it still consumes a lot of energy.

Because a large part of the connection is borne by the nodes, it is now necessary to adjust the structure of the two destinations to be exactly the same as the mapping, so that the burden on the nodes can be greatly reduced, and the energy loss can be greatly reduced through the existing strengthened connections.

As for how much Xiao Chen himself is not sure, but it is estimated that about a dozen ordinary sun stones will do.

This is simply the difference between heaven and earth, you must know that as long as the energy conversion ratio between a piece of the same volume of sun stone and the sun stone crystal stone is far from comparable, Xiao Chen estimates that the energy in a sun stone crystal stone is about worth a thousand sun stones.

Shaking his head, Xiao Chen decided to put this work aside a little, since they already had ideas, then things would be easy to do, and there was no need to rush for a while.

Raising his head suddenly, Xiao Chen was stunned, Hera actually fell asleep on the chair, and the quiet sleeping appearance made Xiao Chen's heart move, but he didn't expect this stupid girl to accompany him until now.

Xiao Chen was really a little distressed, and gently hugged Hera and put her on the bed.

Then, after tidying up the two maps and the Sun Stone on the table, Xiao Chen lay back on the bed, gently kissed Hera's forehead, and fell asleep.

Hera, who was sleeping, had a shallow smile on the corner of her mouth......
