(a)

Let's take a simple chestnut.

I'll give you a cardboard box with ten oranges in it.

I will give you a super awesome Zenith Star Black Technology Swiss Army Knife, which has a hundred functions, can peel, carve, cut pieces, and shred, and can do anything.

The rules are such that only this saber can be used, as well as ten oranges inside the box, and it is forbidden to break the cardboard box. With the above prerequisites, your task is so simple that even a five-year-old can easily do:

That's to peel me an apple.

Okay, now that you're done, you can just let it go. What? You say you can't do it? And say I'm trying to make things difficult for you?

Yes, the reason is already very clear, isn't it? You can't peel an apple from ten oranges, and the guy in your hand is useless, after all, you don't have apples at all.

"Indeed, Bayi Yonglin, you are like a god now. Yuyuko looked up at Yonglin and said, "Eight million gods are like stars, which one are you?"

"You are the god of this closed basement with a radius of two hundred meters. ”

"I didn't mean to bury you, Yonglin. I have seen many gods who are mighty in their realm, but no match for a pebble outside. ”

Actually, you've already recognized this yourself. You can read my thoughts, and you should know that at this very moment, my head is echoing the words you said at the beginning, that you are a 'finite god'. ”

After hearing this, Yonglin's complexion did not change in the slightest, but he just hooked his hand at Youyuzi and said:

"Go on, you still have unfinished business. ”

"Definitely. ”

Yuyuko nodded, then turned back to Youmeng and said:

"Here comes the knife!"

When the demon dream heard this, he didn't say a word, and directly presented the long knife in his hand, the Louguan sword, and both hands.

Yuyuko took the knife, first holding it with both hands, stretching it straight ahead, and then suddenly the blade turned and aimed it at her chest, and stabbed it into it without any hesitation.

The blood, not like a thousand years ago, splashed all over the body, dyed red placket, and dyed very artistically. After all, Yuyuko of Saigyoji Temple is an undead, and the undead do not bleed, and in their place is light. When she pulled the long knife out of her body, a soft cherry glow spilled through the crack in her chest.

Seeing this scene, Youmeng instinctively trembled, her eyes widened, her mouth opened slightly, but she closed it without saying a word—she chose to believe in her master. No matter how exaggerated and unreasonable it seems, Youmu feels that Yuyuko must have a reason to do this. She just needs to be a solid and reliable backing for her master, and that's enough.

As for Bayi Yonglin, she didn't even blink. She had seen it before, just a few minutes ago, in her own spiritual world, in her calculation of the future. So she knows very well that the problem is not with this knife, but after this knife. Up to this point, everything is clear, everything is known, can be known. However, from this knife, her prediction gradually distorted, and she escaped into the dark and chaotic "unknown".

This knife has drawn a dividing line, black and white, just like the horizon when the day is about to end and the night is approaching. From here, she must step down from the altar, step into the unknown, and move forward in the dark. As a scholar, she believes she has an obligation to exhaust this path.

"I've said things like, 'One stone can beat you,' but I'm not really going to hit you with a stone. ”

Yuyuko thrust her hands into the opening on her chest, a smile on her face.

"I'll show you something good. ”

"You didn't come to tonight's cherry blossom viewing banquet in the underworld, I will move it in front of you now. ”

As she spoke, she grabbed the side of the opening with both hands, grabbed the white skin on her chest, and pulled it hard, like tearing open the plastic packaging bag of potato chips, and ripped her skin open. She opened her arms and easily faded the "outer skin" that wrapped her inside, as if she had taken off a piece of clothing, and the cherry blossom light burst out from it, as dazzling as the sun, as warm as the sun.

Yuyuko's form melted in the moment of the burst of light, like a marshmallow falling into the water, and then dissipated in the blink of an eye. But Yonglin can still feel her existence, but in another form, on another level. The bright light was accompanied by the refreshing, warm spring day, and there were even a few cherry blossom petals with forked ends, but Bayi Yonglin only saw a pitch black.

What appeared in front of Yonglin's eyes was not a warm light, but an unknowable and incomprehensible darkness.

"The cherry blossoms have fallen, and the light is a dream. Life is short, I advise you to cherish it. ”

This is Yuyuko's voice, accompanied by a warm breeze, distant and illusory. When the voice fell, the dazzling brilliance faded together, and what was placed in front of Bayi Yonglin was a new world.

The icy metal floor was replaced by a long white jade staircase, surrounded by blooming cherry trees and powder snow.

This is the underworld.

(b)

"As part of the punishment, and as a precaution against accidents, you are sealed in the underworld, or more accurately, in the White Jade Building, where you cannot leave for half a step. ”

In a certain year and month, Zi You and the two inadvertently talked about the incident of a thousand years ago, and talked about the punishment of Yu Youzi by the King of Hades.

"But, didn't I come out!"

Yuyuko nibbled on the fairy shell, puffed out her cheeks, stared at the pair of big eyes, and didn't look serious. With her left hand, which she hadn't grabbed, she pointed to the cushion under her ass, indicating where she was now, the living room of the Yakumo family.

I won't mention where the Yakumo family is yet, in short, Yuyuko is not in the underworld now, which is also the source of her doubts.

"Didn't you say that you were going to seal me in the underworld, could it be that Lord Yama was confused?

"You are indeed sealed in the underworld, and Hades has not missed this point. ”

"But I'm not out!"

"You came out because...... Hey, how do you explain that?"

Yakumo pinched the bridge of her nose in distress, and she suddenly had a deep sense of powerlessness to explain how computers work to people who didn't understand them at all.

"Let's put it this way......"

She turned her head and pulled out a ball of yarn from the cabinet behind her, which she had used to tease Orange.

"Do you see this ball of yarn? I'm going to take this string out of this ball now, is it out of the ball?"

With that, Yakumo pinched the one, tied up one end of the yarn of the big ball of yarn, pulled it out a short piece, and showed Yuyuko to it.

"Uh-huh!"

Yuyuko watched and listened intently, and nodded again, like a good student.

"But can you say that this thread is completely separate from this ball of yarn? No, right?" Purple wrapped the ripped thread back around it, held up a finger, and said, "Because it is this thread that makes up this ball of thread." They appear to be two things, but in fact they are one, even if they are temporarily 'separated', they cannot be completely 'separated'. ”

"The seal on you is not to make it impossible for you to 'leave' from the underworld, but to make it impossible for you to 'separate' from the underworld. The specific operation is like wrapping a piece of yarn into a ball of yarn, turning you into a part of the underworld. The two realms of seclusion and brightness are meaningless to you. ”

"You will no longer go from the light to the dark, that is, to die, after all, you are dead, and you will no longer go from the dark to the light, that is, to be reincarnated and reborn, because you have taken root in the underworld, just like the withered westward demon. ”

"You will always be the ghost of the underworld, forever. ”

But you can be resurrected and retrieve the body buried under the Westward Demon, your own corpse - Yakumo Murasaki would never tell her about it, never.

"Eh, then what will happen if I'm bored and lonely one day and can't think about it, and sneak up on the little demon dream's ghost knife and cut myself with a click?"

"Then what do you think," a light smile of interest appeared on Yakumo's face, "what will flow out of a bowl of water from a water tank and then cut the bowl?"

"Water!" Yuyuko said without thinking.

"The water tank was cut down too, what's in it?"

"There's water, do you still need to ask?"

"Then slash you, what's in it?"

"Slash me?"

Yuyuko tilted her neck, frowned, and thought hard.

"What can I have in my body?"

"Hey—" Purple turned her face away, sighed lightly, and turned back and said:

"Cut the ball of yarn, what's inside?"

"Wool!"

"Then cut the yarn again, what?"

"It's still wool!"

"And what about another cut of wool?"

"How to chop wool, isn't it all wool!"

"That's right, it's not all wool! Then you still ask me this question? Why don't you get yourself a knife now, and it's okay to try it boldly!"

"Also...... Forget it, I'm afraid of pain. ”
