this infinite world

——The truth about the multiverse?

——What truth?
Listening to Hou Tu's solemn answer, Yang Yun blinked his eyes, confusion in his eyes.

"What do you see?"

Just when Yang Yun was confused, Lin Xuwen suddenly asked: "Don't touch it, don't feel it, just use the action of 'look'... and then tell me, what do you see?"

“…I didn’t see anything.”

Although he wanted to say something, in the end, Yang Yun still answered honestly: "There is nothing in front of my eyes... There is nothing, nothing exists."

"Yeah." What confused Yang Yun even more was that Lin Xuwen nodded first, but then shook his head the next moment: "You are right, but also wrong. Let's take a look."

——What's going on? Are you playing a guessing game? Is this something like "The Emperor's New Clothes"?
Although it can be seen from the smiling expression of Hou Tu beside him that this woman with a somewhat... or rather sinister nature is obviously deliberately laughing at him, but Lin Xuwen, who has been quite serious since the beginning, is obviously not the kind of person who has the leisure to do such things.

In other words, in this empty area in front of him, there must be something that Yang Yun cannot see, perceive, or touch.

"Could it be something like 'Schrödinger's cat', which does not exist if we don't observe it?" Thinking of this, Yang Yun asked tentatively.

"That's not the case, brother. It's not 'non-existence', but a 'superposition state' that ordinary people cannot see."

After hearing Yang Yun's answer, Hou Tu smiled and shook her head, saying, "But now your vision has long been sublimated, not to mention that you have returned from a superposition state of neither life nor death before... So, zero points."

"Zero points?"

Listening to Hou Tu's ruthless criticism in a gentle voice, Yang Yun did not feel discouraged at all. Instead, he once again looked at the space in front of him, and after thinking for a moment, he asked again: "Well, just now Lin Xuwen Tower told me to 'not touch it, and not to sense it', and also specially strengthened my vision..."

"If I'm not mistaken, could this be something extremely special that can only be observed by 'looking'?"

Yang Yun knew that there were indeed some things in the multiverse that could not be described by common sense and could not be explained by existing theories. For example, Lin Xuwen's non-existent ability called "The Thousand Worlds Observer"... Then, even if there was something that could only be "seen" by "saying its name correctly or describing its properties", it should be normal, right?
"You can make inferences based on the few words I revealed, which is the thinking of a wise man... but unfortunately, it still fails."

Hearing this, Lin Xuwen glanced at Yang Yun with a half-smile, but still shook his head and said, "I'm sorry, what I said was just literal meaning. As for asking you to 'see', it was just to let you know that if you touch or sense it, you will probably suffer a lot."

"Danger? Is there really something in here?"

Yang Yun was startled when he heard this, and his eyes swept towards the empty space again. But even though he was able to "use golden light in his eyes and shoot into the palace" like a stone monkey, he still couldn't catch any abnormal fluctuations. The area was still empty and pure... He returned empty-handed again, and Yang Yun frowned, and his right knuckles unconsciously tapped the base of his left hand... Could it be that it was not a problem of observation method, but a fundamental difference in cognitive dimension? Just like two-dimensional creatures can never understand the concept of "height", is he also confined in a certain cognitive cage?

——No, I am being too picky again. Lin Xuwen should not deliberately lie or mislead me. He said that his words were just literal meanings...literal meanings?
Suddenly, Yang Yun thought of the situation when he honestly answered "nothing" at the beginning. At that time, Lin Xuwen nodded first, then shook his head, and made an ambiguous answer of "right and wrong", as if he was making a witty response... But what if he was not making a witty response at all, but just meant the so-called "literal meaning"?

"Nothing" is right, but "nothing exists" is wrong.

Because, in that place, there is clearly something...something called "emptiness"!

Emptiness means nothingness, emptiness, emptiness, purity, and non-existence. All existing things have no self, entity, or self, which is called emptiness, which also means the illusion of things, or the emptiness and purity of the essence... And this "emptiness" itself is a concept of "existence"!

“Empty” means there is nothing, that’s right; but “empty” itself is definitely not “non-existence”!
"Very good, it seems that you have understood the concept of 'emptiness'. Remember this firmly, as it is one of the necessary conditions for you to step outside the multiverse."

At the moment when Yang Yun figured it out, Lin Xuwen nodded with satisfaction and spoke again: "Although we two look like Riddlers to you and doing these things is unnecessary, this kind of thing can only be understood by yourself... Otherwise, it will be useless even if we tell you a thousand times."

"I told you that my brother can do it." Unlike Lin Xuwen, Hou Tu said with a smile: "You are just worrying too much!"

"Maybe." Lin Xuwen sighed again and looked at Yang Yun, who was staring at the space in front of him with great solemnity: "So, this is what we want you to see."

"……What exactly is this?"

After understanding the concept of "emptiness", the world in Yang Yun's eyes suddenly changed. The originally empty void was suddenly filled with a certain gray color.

And saying "gray" is more like something of a higher level that is intangible, imperceptible, and yet actually exists here... But it is undeniable that the moment Yang Yun saw that thing, whether it was his holy way, the light of his soul, or the material form that now constitutes his body, all frantically issued warnings at this moment!

"...What is that?" Yang Yun took a step back and saw that the gray did not move forward, but was firmly locked in that area by some invisible force. He was relieved, but still asked nervously: "Why would I..."

"As you can see, once 'emptiness' is understood, it changes into another concept... or in other words, this is its original form of existence that can be observed."

Looking at the gray area after the reversal, Lin Xuwen spoke word by word in an extremely serious tone: "Or, I would rather use another term to describe the 'concept' that is everywhere and at all times outside the multiverse, and can only be observed by a very small number of people. I call it..."
