Moments later, in the depths of Test Area 0.

"This is the practical 'zero drive'?"

This is the location of the core of Experimental Area 0, and it is not far from the Galvin.

However, it is different from what Dagu imagined.

This so-called "zero drive" is not a tall device, but more like a huge arch made entirely of special metal.

Silver-white is its main color, and the arches that have been built through rigorous geometry are its forms.

The only difference between this arch and the other gates is that it has a huge base through which various lines connect the entire institute.

Only through this extensive line can the "zero drive" be truly activated.

"Actually, I was going to put it on the Galvin......"

"However, it is too big as a 'prototype' and can only exist in this way until it is miniaturized."

The voice paused slightly, and Lu Xuan, who was operating at the console not far away, explained without looking back.

"Although there is still a big gap with the theoretical 'speed of light'."

"But short-distance teleportation within the earth is already a function that this machine can achieve."

"When I come up with a real 'infinite energy', this machine will be able to teleport across time and space on an interstellar scale."

"In addition, the 'zero drive' is just the principle of making this machine, and I still prefer to call it 'arbitrary door'."

Hearing this, Da Gu didn't know for a while whether to complain about the name Lu Xuan took, or to tell him that this name infringed on Doraemon's copyright.

"So, you're planning to teleport me directly to the Black Pyramid through this arbitrary door?"

After sweeping away the messy thoughts in his mind in time, Da Gu Qiang held back the excitement and apprehension in his heart and asked.

"It's us, to be exact!"

After setting the coordinates and the teleportation time, Lu Xuan pressed the button that symbolized "start".

- Then, any door activated.

Restless!

Between the lightning and flint, the originally silent Experimental Area 0 suddenly made a loud rumbling noise.

I saw a huge electric current shuttling in the underground cable, with a rushing energy frantically pouring into the base of any door, which made Da Gu feel frightened for a while.

Such a large energy transmission movement, if it weren't for this super research institute a hundred meters underground, I am afraid that it would have alarmed all the energy detection devices within a radius of 100 miles.

In this way, the No. 0 experimental area can only isolate energy radiation, but it cannot completely eliminate the movement of energy generation and input.

"Don't be so nervous, this is just opening up the imaginary space, and it won't cause any other impact."

Very calmly appeased Da Gu, Lu Xuan was already surprised by this.

As if in response to Lu Xuan's words, after a brief surge of energy, the arbitrary door was really opened.

Restless!

In the midst of the geometrically rigorous arches, a black hole that emits a rainbow of light grew out of nothing and gradually filled every crevice of any door.

Through the black hole that emitted colorful light, Dagu seemed to see a space that was very different from the material world.

In that space, there is no concept of mass, no concept of energy, only simple up, down, left and right, and the endless void that seems to be forever black.

"This is the imaginary space, the shadow of the material world!"

Without the slightest hesitation, Lu Xuan stepped into any door after activating his force field generator.

"Remember, I've already set up my target location in advance."

"So we don't have to do anything after entering the imaginary space, just wait for the teleporter to send us to the designated place."

There was some fear, and some anticipation......

Da Gu gritted his teeth and followed Lu Xuan's steps and entered any door.

……………………………………………………………………………………………………

Contrary to Dagu's expectations, when he stepped into any door, he found that he did not appear directly in an unfamiliar location like any door in Doraemon.

Conversely, the inside of any door seems to be a special elevator?

He and Lu Xuan are now standing in this elevator, and they can clearly see the constantly distorted time and space of the outside world, as if they have entered some mysterious other dimension as human beings.

"Well, it's shocking to see the imaginary space for the first time, right?"

With an undisguised smile on his face, Lu Xuan continued to explain.

"The arbitrary door doesn't directly teleport us to a certain location, but it allows us to enter this imaginary space."

"This special imaginary elevator is the tool that is really responsible for getting us to our destination."

"In the imaginary space, this elevator has no quality......"

"So as long as there is enough energy, it can accelerate to a level beyond the speed of light in a short time."

"And we inside the elevator still have the concept of quality, and we will not become some kind of indescribable monster because of entering this imaginary space."

Before Lu Xuan's words fell, the imaginary elevator had already begun to accelerate, and the mysterious and strange scene around him also changed at a speed visible to the naked eye.

"With the current power of the No. 0 experimental area, it can only accelerate this imaginary elevator to about Mach 10."

"But that's enough, a few seconds from the headquarters building to the remains of the Black Pyramid is more than enough."

Before he could recover from the extreme acceleration just now, Dagu noticed that the rapidly changing situation in the outside world had stalled again.

During the whole process, Dagu did not feel the slightest feeling of weightlessness or acceleration.

If it weren't for the fact that the situation of the outside world had indeed changed, Dagu would not even have the recognition that he had just been accelerated to Mach 10 speeds.

"The most important thing is that through this imaginary elevator, we can now ignore the barriers of terrain and landforms, and appear in any corner of the earth."

Gently pressing the door opening button of the imaginary elevator, Lu Xuan explained very calmly.

"If you're interested someday, I can even take you to the magma world in the center of the earth to prove whether the earth is solid or hollow."

Seeing that the imaginary elevator was re-materialized, the strange extradimensional phenomena around it were gradually replaced by material entities......

Da Gu, who knew that the destination had arrived, shook his head decisively, and rejected Lu Xuan's terrifying suggestion without hesitation.

He felt that it would be good for an ordinary person like himself to honestly know the appearance of the center of the earth from various popular science books, and there was no need to experience it himself.
