"Impossible, impossible, how can you not get out!" Bloodthirsty let out a beastly roar as he held his head. Pen "Fun" Pavilion www.biquge.info

"But isn't that what we're seeing now?"

"Wait, now ......" Hearing the curtain's words, Su Zi's eyes lit up suddenly, and the whole person looked like it was back to its original state.

"I know, I know!" Su Zi jumped and laughed.

"Do you know the Klein Bottle?"

Seeing that everyone was confused, Su Zi didn't hide it, and explained directly.

"In the field of mathematics, the Klein bottle is a non-directional plane, such as a two-dimensional plane, and there is no distinction between "inside" and "outside". In topology, the Klein bottle is a non-orientable topological space. ”

Su Zi saw everyone's confused eyes one by one, and shook his hand helplessly, "To put it simply, there is a hole at the bottom of a bottle, and now the neck of the bottle is extended, and it twists into the inside of the bottle, and then connects with the hole at the bottom." ”

"For example, a fly can fly directly from the inside of a bottle to the outside without having to cross the surface, i.e. there is no distinction between inside and outside. ”

When everyone heard this, they suddenly realized.

"So, we're in a room similar to a Klein bottle now?" asked Koto, pushing the black-rimmed glasses that had slipped again.

"Absolutely!" Bloodthirsty looked happy as he couldn't wait to find the hole.

"If we want to find that hole, first we have to think of the space we are in now as a four-dimensional space, not a three-dimensional space. ”

Four-dimensional space?

Thinking like this, the room that was exactly the same as before in my eyes slowly began to become different, as if everything suddenly became three-dimensional, as if it ......

"I found it!"

"I found it!"

After moving his steps slightly, constantly looking up and down with his eyes, several people shouted in unison, and then looked at each other and smiled.

"Why didn't I find it here before, it's amazing" Jiang Dong scratched his head and was a little puzzled.

"Hahaha, that's because now we have opened the eyes of heaven!"

"Erlang God. ”

"What's that?"

"A mythical figure. ”

"Tang Se, come on, talk about it carefully......"

"Yes, yes, we're listening."

The group walked into the cave with a smile and a smile, just as Su Zi said, when they came out of the cave again, they had already arrived at a brand new room.

Maybe they will betray each other in the future, even by any means, but now, but at some point now, everyone's hearts have been on the same page.

Because everyone has overcome a difficult hurdle together, everyone's mental strength has gone up a lot, and I feel that everyone has more hope for survival and life on their faces.

Su Zi was still thinking about those strings of numbers, and now they would get new numbers every time they passed through a brand new room, did that mean ...... They are getting closer and closer to the end.

"This is a voice-activated room," Bloodthirsty screamed as he lay on the ground like a room below everyone's feet, and in an instant, steel needles that could penetrate everyone filled the entire room one after another.

"Why are there so many needle mechanisms here, the people who designed them are really boring. ”

"How can it be more important than this!?

"Also, the other rooms are completely unpassable, it looks like we have to pass this room"

"That'...... Who passed first. ”

“…… Ladies first?"
