By all indications, the last era was closer to Reiner's technological civilization than magic, and the cold metal artifacts we see now are more like the products of mechanical engineering.

High science is no different from magic, and vice versa.

Reiner thought of what a scholar had said in the previous life.

"Lord Hohenheim must have been here before, what did he discover, or was he puzzled by it?"

Reiner walked down the hall as he tried to find the exit, only to find that the room was tightly sealed, without a single door or window.

Pulling his hand back from the same cold metal wall, Reiner confirmed that the place was as if it were inside a tin box, unobservable and unobservable by the outside world.

If it weren't for the rift in this plane, I'm afraid no one would have been able to come here.

"Wait, space-time wormhole ......"

Reiner suddenly thought that if this place was indeed completely closed and only the space-time wormhole could be used to travel to and from it, then did it mean that this space-time wormhole was not accidental, but was the passage to and from this space.

Since in the ruins of the Elliot Halfplane, the mages have seen that the people of the last era have been able to use the Dead Realm to create a wormhole connecting the two places, then this ruin here is completely closed, and it is normal to be able to travel only through the wormhole.

"Can the people of the last era already create space-time rifts at will......

Reiner guessed that being able to create space-time rifts and apply them meant that the research on space-time in the last era had surpassed the current era, and if it was substituted into the technological level of the earth, it was very likely that such a civilization would have mastered the technology to leave its own galaxy to colonize space, or even travel faster than light.

In fact, being able to use wormholes freely is already a certain degree of faster-than-light sailing.

And even such a civilization was destroyed by the Sauron Xenomorph, and Reiner was suddenly very worried about the future of this world.

"It's more like a warehouse of sorts, Lord Reiner."

Halleyson said that she felt that the cubes were somehow similar to herself, but she couldn't say why.

"Warehouse? Well, I just don't know what these cubes are. ”

Reiner touched his chin, thinking about something.

A few minutes later, Reiner's eyes suddenly widened as if he had been struck by lightning.

"That's ...... so"

He whispered as he returned to the side of the space-time wormhole.

"To create a space-time wormhole, we first need to find an area that can connect two space-times, that is, a place with a large enough curvature."

He tore a piece of paper from the back of his notebook and folded it up.

"Space-time is originally uneven due to the uneven distribution of mass, and the basis of the existence of wormholes is to require extreme distortion of space-time, so that the two planes are extremely close together."

He poked his pen in the center of the folded paper, poking a hole in it.

"After finding the right point of curvature, using special means to create a wormhole to connect the two space-time is one way to create a wormhole, but there may be another way."

Reiner said, crumpling the folded paper.

"That's artificially created space-time distortion."

"Artificially made?"

Halleyson didn't quite understand that the spell she mastered could use the unstable half-plane to take a shortcut to some extent, but that was only when she obtained a ready-made unstable half-plane, and wanted to artificially create a space-time warp, and Heatherthan, with her intelligence, couldn't think of what to do.

"To be precise, this artificially created space-time distortion is not the original product, but a side effect."

Reiner laid out the piece of paper and placed it on another table.

"When we move through space, we are actually accelerating relative to space, and thus moving forward, and this speed cannot exceed the speed of light, so navigation in space is subject to this constraint, but what if space itself moves?"

He placed the watch on the paper, and by folding the paper on one side of the watch, he moved it forward, pushing the paper from under the watch behind it.

"If you master such a technique that can compress space-time in front of an object and stretch space-time behind an object, then it is stationary relative to the object, but the object will actually move forward because of the difference in curvature, which can bypass the constraints of the theory of relativity and thus exceed the speed of light!"

Picking up his pocket watch, Reiner looked at the lab.

"This kind of driving process is extremely transformative for the entire space, and the surrounding space will become very distorted, and even the originally flat space-time will produce enough curvature to create wormholes."

In his mind, an awe-inspiring picture gradually emerged.

The people of the last era created a curvature spaceship, and by changing the structure of time, they successfully flew out of the home galaxy, and in the process of sailing, they discovered that such a distortion can cause two space-times separated by each other to become extremely close, thus creating wormholes, and they applied it to build many wormholes.

Even after the destruction of civilization, the remaining people who have mastered this technology are still creating wormholes, but because the space around the planet has been overlapped by the distortion of time and space, these wormholes are just going back and forth in half planes.

In the same way, Reiner suddenly understood how the people of that time had destroyed the Sauron Xeno.

That is to use the effect of the curvature spaceship to compress space, trapping the Sauron xenomorph in the labyrinth of time and space!

And the dead domain is also one of the by-products of the curvature spacecraft.

When the time and space are distorted to a certain extent, the limit of the speed of light begins to decrease, and time is delayed, for some reason, the magic power cannot collapse at a low speed of light, which leads to the creation of the forbidden demon area, that is, the dead domain!

All of this coincided with previous observations, and Reiner remembered that the few of them had only been in the Dead Realm of the Elliot Half-Plane for a few hours, but the time outside had already passed a day, and it was because of the distorted space-time in the Dead Realm!

Now existing in the dead fields of various half-planes, except for some of which already existed, most of the rest were caused by the fall of legendary mages, Reiner guessed that it was the magic tides generated when these mages themselves fell that tore through the space, resulting in the creation of similar low-speed regions.

Because of this, in the dead realm, it is very easy to generate space-time wormholes, and this passage to this facility may be created because of that fallen legendary mage!

Thinking of this, Reiner seemed to suddenly sense something.

"When the last epoch was destroyed, it also produced such an explosion that was enough to tear through space...... In other words, the main plane in which we are now has also been delayed in time. ”
