"So who do you think this person would be? Could it be...... Ganfeng? Professor Wu said cautiously.

"He brought us in at the beginning, so it's more likely that it's him." Zheng Tian replied angrily.

"No, something must be wrong!" Alan Lin said emotionally.

"Do you remember, when we first came in, the hall on the first floor was open, and there was no gate installed at all." Nangong Han pointed in the direction of the door and said.

"yes, I'm still wondering, I don't know where this door came from." Fat Bear said.

Nangong Han continued to explain: "The direction of our analysis was wrong at the beginning, and we all thought it was the control of the organ and closed the hidden door. ”

"Isn't that what happened?" I'm a little confused.

Nangong Han shook his head: "Actually, there is indeed no door on the first floor, and the reason why this gate appeared in front of us is because we are not on the first floor at all, but on the third floor, and there is a sealed door on the third floor." ”

"Third floor? Can...... But the layout is exactly the same as when we came in! Zheng Tian said as he took out the DV and called it back for comparison.

Nangong Han continued: "I have already said that all the rooms here are movable, and the manipulator has replaced all the rooms on the first floor, including this flying fish sculpture in the center, to the third floor, giving us the illusion that we are still on the first floor. ”

I suddenly had a feeling of enlightenment, if the situation is really as Nangong Han said, then from the moment we entered this Flying Fish Building, we were playing with the applause of a mysterious person.

At this time, Professor Wu asked a key question: "But when we were on the second floor just now, we obviously went down one staircase, how did we go up to the third floor instead?" ”

I suddenly realized this, I can believe that the rooms on each floor will change up and down each other, but this staircase that I walked out with my feet would not deceive, we only went up to the second floor, and then went down the stairs, and never went to the third floor at all.

Nangong Han looked at the direction of the spiral staircase and said calmly: "There are some things that seeing is not necessarily believing, for example, we just thought we were going downstairs, but in fact we were going upstairs. ”

“No! No! This is against the law of gravity! John shook his head and said.

"Damn, Newton's coffin board is running out." Zheng Tian also muttered.

Nangong Han continued: "In 99 percent of the cases, this law is indeed violated, but there are still 1 percent that are not violated. ”

Professor Wu was silent for a while and then spoke, "Are you talking about the Penrose Ladder?" ”

"What the hell is this? I said don't talk about these things, bully the fat man and don't read much, right? After listening to it for a long time, the fat bear estimated that his head had already been dizzy.

"It's a classic geometric paradox, meaning an infinitely looping ladder that is always up or down." Professor Wu explained.

I understand what Professor Wu said, taking the current situation, if we take the first floor as a starting point, under normal circumstances, the first time we take the stairs is to go up to the second floor, and the second time we take the stairs is to go down to the first floor, but according to the infinite loop theory of the Penrose Steps, we are still going upstairs for the second time, and we will always be in the state of going upstairs.

But if you think about it, the situation of the "Penrose Steps" is not quite the same as our current situation, because walking on the Penrose Steps, one has an intuitive feeling that one keeps going up, and finally returns to the original point, and when we take the stairs for the second time, we already clearly feel that we are going downstairs, and besides, what we are walking is not an infinite loop of stairs.

Sure enough, Nangong Han quickly denied this Penrose Ladder: "It is a paradox in itself, and it will not exist in this time and space where we are at all. ”

"So Mr. Nangong, can you explain what the 'one percent' is?" Professor Wu asked, holding his chin.

Nangong Han walked to the entrance of the spiral staircase, touched the handrail of the staircase and said, "It's the ascending ladder in the Mo Sect's Organ Technique, which is similar to the path we have been going in the wrong direction before. ”

"You mean this staircase is also a trick to confuse us?" As he spoke, the fat bear leaned over to the stairs, looked around, and then said, "No, unless my eyes are crooked." ”

Nangong Han shook his head: "It's not this staircase, it's the entire building." ”

"The whole building?" The fat bear's mouth opened into an O-shape and said in surprise.

I also felt mysterious when I heard it, and I didn't know what Nangong Han meant.

Nangong Han then explained: "If the whole building is upside down, then what we thought was going downstairs would become going upstairs." ”

"Bump...... Reverse? "None of us can believe it.

"If it's upside down, how can we still stand here?" Zheng Tian tried to jump a few times and asked.

Nangong Han continued: "The building we are in is in the shape of a fish soaring upward, and it is indeed impossible for us to stand here smoothly from the perspective of it as a space alone, but have you ever thought that the space that is one level larger than it, that is, the entire Luoli City is actually upside down? ”

Nangong Han's words made me feel a chill down my spine, and I said in a trembling voice: "If the entire city is upside down, then after the two upside downs, it just offends, and the plane is still horizontal. ”

John shook his head vigorously: "But the space that is one level larger than Luo Licheng is the earth, and this statement is not true at all......"

As soon as John said this, Professor Wu motioned for him to shut up: "I understand, Luoli City is actually a space that exists independently of the earth, which is why so many incredible things have happened. ”

Nangong Han didn't respond, I don't know if he acquiesced or he wasn't sure, after a while, he spoke: "Now that the root of the problem has been found, if we want to go out, we must go down to the real first floor." ”

"But...... There's just a staircase, which we just tried. ”

Nangong Han walked to the flying fish sculpture in the center of the hall and said, "Another very important reason why we were deceived by this staircase is that someone secretly manipulated the layout of the entire floor through this sculpture. ”

After Nangong Han finished speaking, he began to study the flying fish sculpture in detail, although the scales on it were movable and had been artificially moved not long ago, but we couldn't solve the mystery, so for us, it was always fixed. After seven or eight minutes, Nangong Han suddenly remembered something, turned to me and said, "What about your order?" ”?

I was stunned for a moment, then hurriedly took it out and handed it to him: "This ...... Useful? ”

There is also an image of a flying fish printed on the back of the Moment Order, so of course I have long thought that the two are related, and I have already experimented, but I have not found the previous "diamond-shaped fit" at all, so I no longer have any hope for it.

Nangong Han nodded and said, "It's useful." ”
