The non-existent first thought of parallel universes, which is also the easiest one to conceive.

In this scenario, the Forgotten Lands are the nexus of the universe, and everyone who enters them will travel to a different land of the living dead when they come out, which explains why "no one who goes in comes out" and "no one who comes out knows each other".

Regarding this speculation, Hei Li himself is also the best confirmation.

But the non-existent didn't know Heili before entering, he only knew that the person who entered the Forgotten Land never came out again, maybe it was not called the Forgotten Land at that time, it was called the Lost Land or something like that, but even so, he still thought of the parallel universe hypothesis.

In order to confirm or disprove this hypothesis, he left a "mark" in the land of the living dead, the pocket watch at the entrance.

At the same time, he also carried a pocket watch with him, which he used to compare time.

When everything was arranged, he stepped into the land of oblivion.

One day, when he came out, if this marked pocket watch was gone, it proved that the parallel hypothesis was true, and one in and one out, it was already two worlds.

If this is the result, it means that the world is already chaotic and complex to the point of incomprehension, even if you travel around to find the non-existent, but when you come out, you will reach other worlds, in that world it is unlikely that there will be this grand plan again, and the non-existent will lose its final meaning and become the real non-existent.

If this is the case, then you will not go in, and entering it means losing contact forever, exile forever, which is far more terrifying than losing contact with the Earth plane.

[Come to the entrance, adjust the time, or say goodbye to me.] 】

This is what it means to say goodbye.

Those who do not exist will forever be in the Forgotten Lands, waiting for those who did not make their appointments.

But he still waited.

He pinned his hopes on another hypothesis – the black hole of time.

Zhou You couldn't imagine how he came up with this, but when he saw the pocket watch and time, the theory of relativity instantly popped out of his head, followed by a black hole.

"Time" is never an independent existence in modern physics, but a physical quantity that is affected by factors such as gravitational field, velocity, and spatial parameters.

In different frames of reference, it is relative.

A moment in a high-speed spaceship is equivalent to a year on the surface of the Earth.

The last blink of an eye for those who fall into the black hole will last forever in the entire universe.

To understand this, it is necessary to abandon the instinct and understand time as a physical quantity equal to speed and mass, based on the idea that "the running speed of wonton is twice as fast as that of traveling around", and "the time of wonton passes twice as fast as traveling around".

And the time black hole is a place that is "many times faster", and this lot is not tens of hundreds, hundreds, thousands, tens of thousands, but hundreds of thousands, millions of times.

In this hypothesis, the infant existed, but it was a long, long time ago, so long that no one remembered him.

The same goes for Heili and Mozun, Heili feels like he's only been in the Forgotten Land for less than half an hour, but he's already in the middle of nowhere.

This is where the "similar but different" environment he perceives comes from.

There is even reason to believe that all those who entered the Forgotten Lands are still alive now, and for them, maybe only a few steps have been taken.

The infant is still wielding his sword towards the land of the living.

The zombie-like dead man was still staggering.

Those who do not exist are still waiting for a person to come to the appointment.

He exiled himself out of time, only to witness the spark firsthand.

Zhou You told this to the Emperor of the Underworld and Hei Li, but they didn't seem to understand.

Indeed, this has long gone beyond intuitive common sense, and even those who have been systematically educated in the human world may not be able to understand it.

In the end, Zhou You can only tell them in the vernacular - one day inside, one year outside.

"Why?" asked the Immortal Emperor.

"The hell TM knows why, I don't even understand π. Zhou You shook his head and smiled, "Even in the human world, it is only to summarize the laws of appearance and put them into practice, and only theologians will try to answer the question of 'why the laws are like this'." ”

"Let me say that the world is a big turntable with many grids. Hei Li gestured to the side, "It's always turning, we're just one of the small grids, the Forgotten Land is the middle passage area, and when you go in and come out, you will randomly enter a grid, I'm just an unlucky guy, and I've entered the grid of the Stupid Emperor." ”

"Hahahaha. The Emperor laughed and said, "You're lucky, a real tyrant will crush people like you and feed the horses, and Lao Tzu thinks you're having fun so I can arrange a place for you to live." ”

"If that's the case. Zhou You smiled and pointed to the dark area in the distance, "Why don't you go in and out frequently until you return to your own world?"

"That's dangerous. Hei Li glared and said, "There are all kinds of weirdos in it, the turntable is always spinning, and the position will be different every time you enter and exit, maybe you are unlucky to meet some terrible guy when you go in?"

"Well, invulnerable......" Zhou You gave up.

"Hahaha. The Immortal Emperor laughed and said, "Lao Tie, are the so-called scientists you are talking about just a bunch of such gods?"

"There is also this, which we call Minke. ”

……

After a while, the group came to the entrance of the Forgotten Lands.

Zhou You realized that he had seen this place a long time ago, but at first it was far away, he thought it was a dark night sky, until he "ran" in front of this night sky, he found that it was a void without any color fluctuations at all, up and down, left and right, like a black dome enveloping the world.

As for this entrance, it is just the entrance that people here have agreed on, in fact, there are entrances everywhere.

Zhou You easily found a pocket watch floating in the air, and the position was not high, only up to the neck of the Immortal Emperor.

It is not in vain that the non-existent waits, hope is approaching.

He rode over, and his first reaction was to touch it, but his hand passed through it and touched nothing.

To be exact, the hand was not pierced, but was cut into two sections, one on Zhou You's body, and the other on the other side of the pocket watch, through the gap of the pocket watch, you can even see the cross-section of Zhou You's wrist, and the blue blood is flowing slowly.

Although it seems to have been cut off, Zhou You is still moving subjectively, and there is no abnormality in the slightest.

"Oh mom!" Wonton jumped off the horse in fright, "It's a long life, the store manager has become a ghost!"

"Hahaha, this one is fun. "The Emperor of the Underworld also stretched out his arm like Zhou You, and his arm also became two, without blood, and the half of his hand floating in the air could even grab Zhou You's hand," This pocket watch seems to be wrapped in an invisible bubble, and it can't get in, so it can only be worn through, but it's not actually going through...... But...... Let's go over it. Anyway, this thing is more interesting than the spatial magic of the High Demon Plane. ”
