Chapter 2580: Plane Barrier and the Ether Interlayer

The Principles are actually very simple.

If one looks at Folded Space from inside a Plane, that hidden space is effectively non-existent due to the separation of the Plane Barrier; only by untying the "knot" between the two spaces can they be connected.

But from the perspective of outside the Plane, these two relatively independent spaces still share the same Plane Barrier, even though the concept of a Plane Barrier is not actually a physical object, but rather the boundary between the Plane and what lies outside the Plane.

However, one can also reach any part of a Plane through this boundary.

To a certain extent, what the "knot" between two spaces constrains is this boundary between the Plane and the outside of the Plane.

Of course, this is in theory; the difficulty of actually doing it is no less than creating a brand-new Teleportation Spell, but Xia Duo is confident he can complete it!

If his idea can be realized, it could even be used to search for the Eastern World!

It is just that the Eastern World is not like Feres Fortress, where he has already discovered the "knot" of the Folded Space; searching for it would still be very troublesome.

But the Eastern World also has a point that stands out more than Feres Fortress, which is that the space is large enough; if it really is in the Main Plane, then it is almost as if half of the entire Main Plane has been separated off.

Such a large target should be relatively obvious if searched for from outside the Plane.

Do not look at how Xia Shao and even few Netherese Mages cannot project their Perception into the Ether Interlayer; if one wants to enter it personally, there is only one result—collapse and disintegration!

One is an existence that cannot be mass-produced, or even artificially created, while the other has already achieved mass production; how to choose does not even require using one's brain to consider.

If I can complete the entire process of space folding within ten minutes or less, then I might really be willing to gamble, or gamble that the Main Plane can withstand a faster folding process.

The difficulty of operations inside and outside a Plane is completely different; the size of the space that needs to be folded is different, the operational difficulty is also different, and it even has to do with the completeness of the Plane.

Should be!

Labyrinth Laboratory.

……

Xia Shao had never thought before that space could be operated on in such a way; it can be said that even if he had not discovered Feres Fortress this time, this Arctic exploration would not have been a wasted trip at all, and it could even be said that it opened up a brand-new horizon for his research in the Plane Domain. ……

Not to mention, it took Xia Shao a whole day just to fold a tiny Semi-plane; if he were to operate on the Main Plane, he still does not know how long it would take!

Of course, Planes also exist within the Ether Interlayer, but a Plane does not belong to conventional matter or energy; the reason a Plane can exist is because a Plane Barrier has formed.

Xia Duo quickly cleared away the residual traces of the previous Plane collapse experiment, then took out a ready-made Semi-plane again to reproduce the operations from when he was studying the suspected magic traces in the Feres Fortress area.

Having completed the space folding experiment, Xia Shao very quickly began exploring the boundary inside and outside the Plane Barrier; the interior of the Plane is the Plane body itself, which is the collection of all matter and elements.

The reason lies in the fact that Xia Shao can only untie the space knot but has no way to re-fold that area, to tie a knot and hide it.

To be honest, if it were not for getting inspiration from the magic traces in that abnormal area in the Arctic, Xia Shao would not even have thought at all that this thing could actually be constrained!

From the perspective of an ordinary person, this process is extremely calm; one would think that even if the space were connected, that person would not notice anything, and would only find that a part had suddenly been added to the normally empty space.

The only substance or strange energy structure discovered so far that can stably exist in the Ether Interlayer is the Plane Crystal!

But as Xia Shao tied a "knot" between the two spaces, from the internal perspective of the Semi-plane, the originally normal space instantly became half as small.

If one were at the scene, one might not feel anything at all.

That is, by constraining the Semi-plane from the outside to make it form a structure similar to a gourd; having experienced the Plane collapse experiment, Xia Shao has gained a bit more understanding of this so-called "Plane Barrier."

This is somewhat similar to the vacuum ground state of the Earth's Universe, and it will convert any matter within it into the ground state.

It took a whole day for Xia Shao to complete the external constraint of a Semi-plane with very limited internal space; looking at it from the inside, this Semi-plane had almost no changes at all.

The so-called body refers to the collection of all elements and matter inside the Plane; operating from the outside makes it very easy to accidentally touch the body, causing the constraint of the Plane Barrier to turn into the constraint of the Plane body.

It is just that in this way, while it is simple for me to enter that place suspected to be Feres Fortress, that area is also effectively undefended; as long as someone has a whim to come and take a look, this matter will not be able to be covered up.

Actually, Xia Shao could gamble now, gamble that no outsider noticed his process of untying the space knot; as long as no one noticed this process, then even if the space is exposed later, it is highly likely that no one will notice.

And outside the Plane is a void Ether Interlayer.

It can even form a hidden Folded Space due to the constraint!

Inside the Laboratory.

And the Ether Interlayer is considered the place where the edge of the Ether Plane merges with the Elemental Plane in concept, and it is also the origin and dwelling place of all Material Planes.

It is not as Xia Shao initially guessed, that the movement perceived by ordinary people would be extremely large, just like suddenly stuffing a large object into that space, but in reality, it is the connection of two spaces.

Looking at it from the inside, the terrain structure and the size of the space suddenly underwent an incomparably huge change, but in reality, it is more like the "curtain" covering the original part was removed; if one cannot perceive the existence of the "curtain," then all of this might just be an incomparably quiet natural phenomenon in the eyes of an observer.

But when there is a choice, it is better not to be such a gambler.

He even thinks that the reason his previous constraint experiment led to the collapse of the Semi-plane was to a large extent not because the method was wrong or the constraint force was too great, but because he accidentally touched the Plane body during the experiment.

And the Plane Barrier is not a concrete and independent existence; it is actually the process of change from the Plane body to the Ether Interlayer.

In fact, if Xia Shao could use a Normal Plane to conduct experiments, the results might be different, but after all, this is more of an exploratory experiment, and he really cannot bear to use a Normal Plane.

Moreover, the only Normal Planes he has on hand are the Blue Crystal Plane and an experimental Plane gifted by the One Tower; the former is in a state of collapse, but even so, it is many times more precious than a Semi-plane!

And the Plane body is related to the Plane Root; once the change is too great, it may lead to the collapse of the Plane. Normal Planes are like this, let alone a Semi-plane that is fundamentally incomplete.

This time, Xia Shao's operations were more precise; he would rather do less than risk touching the Plane body, and so time slipped away bit by bit in such an experiment that was almost like dawdling.
