"What does the invitation mean?" asked Helen, curiously

"Uh-huh·······" Zhou Feiyu hesitated for a moment and began to explain

"I told Delia earlier that some of the key items are the keys to the 17 steps, and although you can break in, you will be attacked, but this description is a bit inaccurate. ”

According to the wave equation, two solutions can be obtained, that is, the real number solution and the imaginary number solution, the real number solution corresponds to reality, and the imaginary number solution is generally meaningless, but if it is in ¥@%... The situation makes sense, that is, ······"

"Stop, stop. Helen directly pressed Zhou Feiyu.

"What's your pronunciation?" Helen frowned.

"Huh? I'm talking about ¥@%... Ah, what's the problem?"

"No, no, we can't hear clearly, it's like, it's like we've been confused by other voices. ”

Zhou Feiyu frowned, he knows what this is, this is called "indescribable", when some groups are completely unable to understand certain concepts, this situation will occur, that is, they can't hear clearly, this is actually the brain's hands and feet in order to protect themselves, because if you force it to listen to it when you can't understand it anymore, then it will lead to a direct mental breakdown.

"Forget it if you can't hear clearly. As he spoke, Zhou Feiyu took out his notebook.

"Then I'll keep it simple. Then he tore off a piece of paper and wrote reality on one side and imaginary numbers on the other. By the way, two villains were drawn on the front and back of the paper.

"In the real world, it's here, that's us, we don't have access to the villain on the back under normal circumstances. ”

The crowd nodded.

"However, imaginary spaces are like mirrors in the real world, and each imaginary space has a corresponding space-time······ The key is more accurate, as long as you have the key, you can enter the corresponding space on the back with a little ritual. ”

As he spoke, he pierced the paper with his pen.

"It's like this. ”

"And if I'm not mistaken, then these earrings are the key to triggering the real 17 steps, and the previous rumors were nothing more than false rumors. ”

Everyone suddenly realized.

"Let's go, go meet this undead. Zhou Feiyu said.

The group came to the abandoned teaching building, the teaching building is not very big because it is an old building, but because no one has cleaned it all year round, the whole building is aging very quickly, and the weeds around the teaching building are already half a meter high.

If it's not really weird, then it's perfect as a horror movie setting.

The teaching building has three floors in a staircase, and they only need to go up the stairs on the left, and when they step on the 17th level, they can enter the imaginary space at the back of the world.

Everyone slowly opened the door of the teaching building, and the turbid air leaked out of the building, causing everyone to cough. Zhou Feiyu held the earrings in his hand and walked in slowly, the teaching building was wooden, and the wooden planks squeaked like a ghost when they walked up because of aging, which was particularly infiltrating.

On the way to the stairs, Zhou Feiyu and his entourage passed by several classrooms, and the things in the classrooms had been emptied.

"It's very well preserved here. Ivy whispered

Helen shrugged.

"yes, it's a pity that there is such a rumor here. ”

And Delia and Zhou Feiyu didn't speak, Zhou Feiyu walked in the front, Delia walked behind the back hall, the teaching building was very small, and it was just a blink of an eye to walk near the stairs.

A group of people stood at the top of the stairs.

"This width only allows two people to go side by side, I'm afraid one of them must have an 'invitation' Although we have an invitation, it is not certain whether we can come back, is anyone willing to accompany me, except for Ivy.

"Why should I except?" said Ivy, a little dissatisfied.

"Because if something goes wrong only you can save me, how to save me, you can definitely figure it out, but neither of them can do it. ”

"Stop, are you looking down on us?" Delia was also a little angry.

"Do you know magic?"

"I ······"

"But I still have science. Delia thought for a moment and came up with a far-fetched reason.

“······”

"Don't you speak, do you look down on me?"

“······”

"I'll go with you. Helen suddenly opened her mouth to speak, and everyone looked at Helen, and the corners of Helen's mouth rose slightly at this time, which made people a little unpredictable.

In fact, Zhou Feiyu's assumption was a little off, I would have thought that Delia would accompany him in, but I didn't expect Helen to take the initiative to bring up this matter, in fact, Zhou Feiyu has basically not gone out in the dormitory since the beginning of school, so except for Ai Wei and others, they are not very familiar with it.

"Okay. Zhou Feiyu and Helen walked up the stairs hand in hand. Zhou Feiyu smelled the strange fragrance again at this time, the fragrance was close to the fragrance of flowers, but he couldn't identify what kind of flower it was at all, and it would make people feel greasy.

This is not the first time I have smelled the body fragrance on Helen's body, I have encountered it before, but this time it is more intense than before, probably because of the narrow space, Zhou Feiyu also deliberately tested with Ivy after smelling this body fragrance last time, and found that Ivy's body fragrance did not feel this way.

Zhou Feiyu nodded his forehead and rebuilt the spiritual barrier. That greasy feeling makes people feel unusually relaxed, but for the current situation, it will affect his judgment.

And Helen next to her seemed to have the same reaction, but she didn't build a spiritual barrier, and only used her strong willpower to suppress it.

But it would be impossible to say that it had no impact at all.

"Let's ↗ go," the last one was visibly a little shaky, and the tone of the note was a small tug.

"Ahem. Ivy coughed in the back.

Zhou Feiyu immediately straightened out: "Then let's start." ”

Then Zhou Feiyu let go of Helen's hand, put the earrings in his hand, and held the hand with the earrings and Helen together.

"This guarantees that both of us are "in possession of an invitation", so let's go. ”

The two walked up the stairs together, 1, 2, ······ 15、16、17。

The two of them went up the seventeenth step.

"That's it. ”

"Hmm. ”

The two of them walked up the last staircase together, to the second floor, and then ······ Nothing happened.

Pair ······ Nothing happened.

Helen chatted about her hair.

"Well, is it useless?" asked Helen, somewhat surprised.

Zhou Feiyu also frowned, and just as Helen wanted to turn back, Zhou Feiyu suddenly reached out and pressed Helen's head.

"Can't go back. ”

"Why?"

"I ask you, what season is it. ”

"Alas, autumn ······" Helen immediately understood the reason, she brushed her hair just now, she didn't have this habit, Helen touched her forehead, I don't know when fine beads of sweat have appeared on Helen's head.

And now it's autumn, why is it hot yourself?

"It's ······"

"The real world is when autumn is about to reach winter, while the imaginary space is the opposite, that is, when spring is about to enter summer. ”

"Then what do you mean you don't let me turn back?"

"This is a taboo in the world of imaginary numbers, everything in the world of imaginary numbers is meaningless, there is not even the concept of 'death' here, it is precisely because this world has no meaning that meaningful things need to be supplemented, and if we turn back, then we are equivalent to 'reversing' in the form and we will become meaningless, become part of the imaginary number, don't believe it. ”

Zhou Feiyu took out the paper he had used to demonstrate, turned the paper 180 degrees with a slight turn, and in an instant, countless tiny "hands" appeared from the darkness and snatched the paper from Zhou Feiyu's hand and dragged it into the darkness.

“······”

"In that case, we wouldn't be able to find the person who sent the invitation. ”

"No, there is a way, but you need to cooperate, because if I let go you may be ejected into the imaginary space, and we both must keep this earring in our hands at all times. ”

"How do you feel that it's not the first time you've entered the imaginary space?

In fact, it is really not the first time that Zhou Feiyu has entered the imaginary space, there was a completely unlocked imaginary space when he was in Blue Star before, as long as you wear protective clothing, it doesn't matter if you spin and jump in it.

And now there is no help from protective clothing, so caution must be taken.

"I'm taller than you, I'll stand behind you, and if it's okay, let's get started. ”

Helen immediately understood what Zhou Feiyu meant, and nodded.

Because Zhou Feiyu was standing on the left side, Zhou Feiyu put his left thumb and index finger deep into the hands held by the two and touched the earrings, and then Zhou Feiyu let go of his right hand and slowly moved behind Helen, showing a state of sticking to Helen from behind.

"Oooooo Helen muttered quietly, Helen knew that Zhou Feiyu was a man, but when she touched it at this time, she found that Zhou Feiyu's body was not as strong as the people around her boyfriend said, but quite soft, as if there was no muscle.

But this is the first time Helen has been hugged by other boys like this, and she can't help but bump into the path, but suddenly a sense of disgust arises from the bottom of her heart.

At the same time, there is a foul smell.

"Hold back, the imaginary space has already had some impact on our thinking, and we can get things done and get things done quickly. ”

Truth be told, Helen was on the verge of throwing up, for she couldn't stand the feeling of nausea and disgust.

"Hold on, if you pop up the space, your current state will be turned over. Don't think about anything. ”

But Helen seems to have been severely affected, and her body has begun to struggle, and she is trying to start turning around.

Zhou Feiyu immediately shook off Helen's hand, and at the moment when the token was taken off, Helen's figure disappeared from the imaginary space without a trace.

And Zhou Feiyu tilted his head.
