As Mu Cang Youyou's words shook the quantum fluctuations and spread to the surrounding void, this four-dimensional cave that seemed to be only a few meters in size and changed its shape without any reason suddenly flashed with brilliance and rumbled like an explosion rapidly unfolding towards the starry sky.

, the expansion speed is...300,000 kilometers per second.

What is even more terrifying and bizarre is that every second that passes, the expansion speed of this four-dimensional cave will increase again.

The 'size' expanded to 350,000 kilometers in one second, to 400,000 kilometers in the next second, and to 500,000 kilometers in the next second.

In just a few seconds, the four-dimensional cave expanded to occupy millions of kilometers of interstellar space, and it is far from stopping.

During the continuous rapid expansion, the specific shape of this four-dimensional cave made of crystal diamond-like material was completely revealed.

This is a collection of points and lines that occupies about three million kilometers in three-dimensional real space and time and is expanding at an extremely rapid rate. It is constantly rotating and showing strange angles and proportions.

In the process of its 'size' expansion, which continues to expand and skyrocket every second, all blocking materials, whether interstellar dust or large meteorites, are instantly cut and shredded into countless basic particles, while releasing a large amount of light and heat, and then again

Devoured and absorbed by it without mercy.

It can only be said that things in the three-dimensional world simply cannot resist such dimensional changes.

To put it more fashionably, this is also a dimensionality reduction attack.

In fact, the rotation and changes of the four-dimensional cave sky are all moved by Mu Cang's thoughts.

One thought can be dispersed or combined.

At the same time, the true scenery of the four-dimensional cave he unfolded can only be seen clearly with a four-dimensional vision, and a four-dimensional brain is required to fully understand it.

Because it is a four-dimensional hypercube consisting of eight regular six-sided cubes, with sixteen vertices, thirty-two edges and twenty-four faces.

It is characterized by eight regular six-sided cubes connected face to face, and each face is shared by two regular cubes.

Life in the three-dimensional world will never understand how eight cubes must be placed so that two cubes share each side.

If we have to forcefully understand the hypercube, we can only barely imagine projecting it into a three-dimensional space in a specific posture and at a specific angle.

And when two cubic cells of the hypercube are exactly 'parallel' to the space of three-dimensional life, he will see two standard cubes existing at the same time.

That is, there is a big one on the outside and a small one on the inside.

The remaining six cubes are manifested into prisms and corners.

Of course, in the three-dimensional world, those cubic cells are extremely distorted.

But in the four-dimensional world, these eight cubic cells are still very standard cubes.

However, once the posture and angle of the hypercube change slightly, it will become extremely indescribable in the eyes of life in the three-dimensional world, and even cause the brain to idle and the soul to be damaged.

And going one step further, if there is a three-dimensional intelligent life that unfortunately enters a certain [face] (cubic cell) of Mu Cang's four-dimensional cave, then he will discover a terrifying fact:

In this huge boundless cube, there are obviously 'portals' on the six huge walls up and down, left, right, front and back, but no matter how much he flies or walks, he can never get out of this 'different-dimensional space'.

(The specific situation can be compared to the four-dimensional maze in the movie "The Fluster 2")

After more than ten seconds, the four-dimensional cave sky has expanded to a range of hundreds of millions of kilometers.

After reaching such a huge 'size', the cave entity suddenly trembled slightly and suddenly split into a huge hypercube cell that also reached a 'size' of hundreds of millions of kilometers at super speed.

In an instant, Mu Cang's four-dimensional cave sky evolved into a twin four-dimensional hypercube, and began to expand more crazily into the void on all sides.

And in the more distant starry sky.
