When he opened the door, he still appeared in front of Luo Yi with the endless depth of the scene.

Thinking about the unknown door in his heart, Luo Xiang walked deeper.

After a dozen steps, Luo Yi's body began to fade and disappear, just like the previous Saint Theseus.

But in Luo Yi's senses, he kept moving forward, and the surrounding environment seemed to dissolve, and then solidify, but it was completely different, as if the world had changed.

The surrounding environment is similar to before, the earth and sky are still mirrored, but the mirror surface has changed from black to pure white.

In front of Luo Yi, a human-high door stands quietly, without any peculiarities, adhering to the style of the student's door, which is a standard rectangular door, as if the space has been cut.

This is the Gate of the Unknown, one of the three buildings that the academy shows, the other two being the student rooms where they live, and the intellectual world.

It's also a mysterious academy anyway, just three things, Luo Yi feels too simple, of course, maybe there are special college buildings in the higher college dimensions, Luo Yi didn't delve into it.

According to the description in the notepad, the unknown door is the way for students to learn, and through it, they can randomly reach any world, yes, any world.

According to Loe's understanding, everything that can be seen outside the academy may not be understandable, but it can be briefly described by the eleventh dimensional theory of science.

Dimension 0: Countless points!

1st dimension: countless lines!

The second dimension: countless faces!

The third dimension: countless three-dimensional, constituting a little reality!

The fourth dimension: a little stretch of reality forms the dimension of time!

Fifth dimension: Possibility of branching of all timelines (faces of the three-dimensional world)

Sixth dimension: the possibility of jumping on the plane of the time axis (the three-dimensional world is made up), that is, the "infinite universe" composed of space at all points in time

Shrink the infinite universe to a single point!

Seventh dimension: Other universes that may be completely different from the rules of our world (infinite universe pulled into a line)

The Eighth Dimension: The Set of All Universes with Different Rules from Our World (Faces of the Infinite Universe)

Dimension 9: The Possibility of Jumping Between Completely Different Universes (Three-Dimensional Composition of Infinite Universes)

Shrink the ninth dimension to a single point

Tenth dimension: The tenth dimension is the collection of all possible universes into a single point.

Because all possible universes are already counted in it, it is impossible to naturally have a higher dimension, because everything possible here includes all impossibilities in a broad sense, existence and non-existence will be included, and there is no transcendence of all possibilities, because even if they appear, they are included in the possibilities.

In addition to this, it can also be explained by the theory of all sets, such as all time, all space, all possibilities, all universes, all physics, all infinity, all concepts......

Behind the Unknown Gate is a collection of all these things, including known academies.

The theory is just an explanation, it does not mean that the forces of each dimension will be so clearly divided, sometimes the dimensions will intersect and overlap, resulting in the emergence of many special worlds or universes.

And the students are to learn the unknown that collides with it, and turn it into their own knowledge and strength.

The Unknown Door has a black seal that looks like a black light curtain.

Luo Yi stood in front of the unknown door, he felt that he could communicate with this portal, and the thought in his heart rose, and the world appeared simultaneously on the black light curtain, and a three-dimensional pattern of the world was projected.

Luo Yi wants to rise to the second dimension, he needs knowledge points, or to meet the student standard, he doesn't know what the standard is, and after thinking about it, it is more reliable to accumulate knowledge points.

For Luo Yi, this is the first time to learn, and there are countless world choices behind the unknown door, he thought about it and set the key word as earth, because most of the memories in his mind are in line with the common sense of the earth, and the world that can be familiar with it will naturally go to the world that he is familiar with.

Moreover, Luo Yike has not forgotten, seven-year-old me once said that before he entered the known academy, he lived on Earth, and if possible, he also wanted to find his traces.

Standing in the white scene, Loe's dark eyes reflected the information on the black light curtain, on which were all the relevant information about the earth, and in the lower right corner, the number of pages was infinite.

The earth world here contains various types and dimensions, and even some of the earth's timelines or worldlines themselves are infinite.

The Unknown Door is quite advanced, although it seems to be a choice of projection world, in fact, Luo Yi can view it in his mind, and he can view hundreds of world information in an instant.

Loe once saw a sentence in a memoir written by me when I was fifteen years old, and he agreed.

There are unknowns in every world, small unknowns in small worlds, and big unknowns in big worlds.

Soon ten minutes passed, and Luo Yi no longer knew how much information about the Earth World he had read.

In the end, I was helpless, because there was not much information to judge in the overview of these worlds, and how many unknowns and dangers the world contained were naturally not marked, and there was no way to mark them, only by relying on their own judgment, if you are lucky, you can find an unknown world that is not dangerous but has a very valuable value, and it is not impossible for bad luck to hang up not long after entering the world.

"Earth-wide random selection."

Loe said to the Unknown Gate.

The next moment, countless white characters on the black light curtain jumped, so fast that they surpassed time, making it impossible to see clearly.

Three seconds later, an overview of the Earth world emerges.

Name: Earth

Type: Real world

Environment: Interstellar Technology Universe

Earth Human Time: The Beginning of the Earth – May 32, 3022 AD

Unknown Overview: The unknown power leads to the imprisonment of time, and there is an extra day of aimless swimming back in the timeline, and human beings are moving along the time in a daze, but they don't know that there is a mysterious unknown quietly coming.

Learning Purpose: To explore the unknown for one more day.

"One more day, is there a mistake in the timeline?"

Luo Yi glanced at the overview, but then he noticed that something was wrong, and kept thinking, "The change of time is only the effect, not the source, and the unknown power is the point." ”

Luo Yi thought about the overview of the world repeatedly, and was a little hesitant, according to his current "new" state, it was best to find a seemingly relaxed world to adapt to, but a world that was too relaxed had nothing valuable to know.

"Well, let it be, the more complex unknowns can learn more, and I don't have time to get used to it."

Half a minute passed, Luo Yi figured it out, and with a faint expectation, walked into the door of the unknown.
