The Klein bottle mentioned by Wen Fang is a conjecture in the field of mathematics! ,
She said that this bottle is different from the cup we usually use to drink water. This thing has no "edge", that is, its surface will not end.
What is the thing without sides
Most people's first reaction is definitely a round "ball"!
However, this thing is different from a spherical surface!
Wen Fang used a very abstract metaphor to describe what this bottle looks like!
Its general structure is like this: a bottle with a hole at the bottom, now extends the neck of the bottle, and twists into the inside of the bottle!
Then, the bottleneck is connected to the hole at the bottom.
At this time, if there is a fly in the bottle itself;
Then this fly can fly directly from the inside of the bottle to the outside without passing through the so-called surface, that is, it has no distinction between inside and outside.
Wen Fang even said and made gestures. After a lot of effort, we only got a little vague impression!
After that, she continued:
"The Klein bottle is just an idea in topology at present!"
"They believe that this kind of magical bottle cannot exist in our three-dimensional space, but can only be established in a higher-level space!"
"I think that instead of using Tai Chi fish to describe the two volumes of the heavenly scriptures, it would be more appropriate to use this Klein bottle!"
"It's like, the body of the underwater building is a normal bottle, and the dakini uses the power of the two volumes of heavenly books to twist the'bottleneck'!"
"Therefore, a channel'both inside and outside the bottle' is created in the bottle!"
"However, this passage is separated from the bottle itself!"
"Perhaps, we have been in such a passage, observing the situation in the bottle!"
"And we finally escaped into the worm path, it should be the specific manifestation of the power of the'twisted bottleneck' of the heavenly book, which can also be called the extending'bottle mouth'!"
"Later, we grabbed from the mouth of the bottle before the heavenly book and the bottle body were connected together, and jumped out beforehand, so we returned to the original'inside the bottle'..."
"You... can you understand?"
I was stunned, and said to my heart: This beauty, not doing mathematics is just a shame! This was originally a simple situation, but it was so complicated by her that the ghost could understand it!
However, I must not lose my face on this occasion!
So I bit my head and slapped haha, looked at other people contemptuously, and said without pretending to understand, "Ah~~I understand, I barely understand! This bottle sounds interesting too! What day! Invite a brilliant porcelain master to figure out a way to play with it!"
"Yes, yes, you have to build one out and feel around!"
The old bandit was desperate to save face. Hearing this, he immediately echoed in a serious manner: "Boy Yan, this is a coincidence! Uncle, I used to travel north and south, and I have met a lot of talented craftsmen who burn clay and make pottery. I went to visit the two. You guys, get us out of this bottle properly!"
Wen Fang saw that we were talking nonsense, and he couldn't laugh or cry, and brought the topic back to formality, and solemnly said: "Okay, that's what I said. Look at the two of you who are pretending to be crazy... The next question-where did those soulless corpses come from?"
I have just considered this issue carefully, and upon hearing this, I immediately said, "Where did the soulless corpse come from? I'm afraid it will temporarily become an unsolved case!"
"In short, judging from the monster's fear of the insect path, it is definitely different from our original expectation. It can't be from the underwater ice palace!"
"Plus, there are no other secret passages in the ice cave. I think those monsters may have come from outside the ice cave after we entered the space of the heavenly book!"
"Furthermore, their movements on the passenger ship at that time were quite weird, as if they came across a relatively new thing while on the way, and they all ran on the deck to see it fresh!"
Upon my reminder, Wenfang and the others fell into silence...
After a while, Wen Fang grabbed his chin and said, "I heard you say that, it seems like this is true... However, there is another problem: if those soulless corpses come from outside the ice cave, then they From which direction did it go? Is it front or back?"
I was taken aback, to be honest, I really haven't considered this issue! However, after thinking about it now, I can barely determine one or two.
At that time, some of those monsters were floating on the water, located behind our passenger ship, all looking at the direction of the passenger ship, I think they should come from behind our ass!
Rapp has the most say in this aspect and immediately expressed his support for my idea, just as the fish in the creek will not turn, the ice cave channel is gorge, the soulless corpse in the water almost fills the river, this kind of group The action in a group is like a herd of yaks passing through a tunnel, which can only move forward in a straight line.
Therefore, the direction of the soulless corpse at that time should be the same as that of the passenger ship! Reverse reasoning, then they naturally followed us from behind!
Wen Fang nodded seriously!
Then he suddenly asked: "Since the heading of the soulless corpse is the same as ours, have you ever thought about where this monster came from outside the ice cave?"
"Also, what is their purpose for entering the ice cave? Or in other words, is their goal the ice cave, or somewhere further ahead of the ice cave?"
I understood Wen Fang's meaning in an instant, and opened my mouth just to talk!
Who knows, Yu Mingjie stepped in, determined to carry the fool's spirit to the end, and eagerly replied: "This question is not easy? Those soulless corpses definitely come from near the middle reaches of the town!"
"Maybe, we were wrong. The town was turned into a corpse of a soulless corpse by the burial chamber. The gathering place is actually somewhere in the middle reaches of the river!"
"And since we only looked after the Spirit Devouring Jellyfish, we didn't find the hiding place of those monsters!"
"Then, our movements on the surface may have stimulated them! So, we followed all the way!"
After all, this guy swept across everyone's faces triumphantly!
This time even the old bandit was speechless to him. He directly broke the contradiction in his reasoning without annoyance, and asked: "Boy, what if: You have a large double-layer cage now with a group of rats underneath! There is someone on top of it. Running after chasing a big fat cat, what would you say to the mouse underneath?"
"Nonsense, of course it will scare you to death..."
Yu Mingjie spoke without thinking about it!
However, before he finished speaking, he suddenly stopped talking, and finally reacted, annoyed: "Damn, I almost forgot, the soulless corpse is very afraid of those big jellyfish!"
After this episode, everyone's attention quickly returned to the original topic!
Since the appearance of the group of soulless corpses is too abrupt, right now we face this topic, and there is a feeling that we have no way to start.
When we were at a loss, Rapp suddenly said, "My little boss, get down from the bow! The ditch underneath is full of icicles, and it's terrible to fall down!"
Caught off guard, everyone was taken aback by him.
My heart pounded for seven or eight times, and suddenly I felt something strange. Everyone is here. Who is Rapp talking to
However, as soon as this idea came up, I was discovered by the other, and I was half-deadly frightened-Ah Da, who was next to me, didn't know when it was gone!
My scalp was numb to the back of my ears, and I silently prayed: It’s not Ah Da, it’s not Ah Da, God, but don’t be him for kilowatts!
Turned around tremblingly and looked at the bow.
Immediately, my eyeballs almost ran out of my eye sockets!
I saw that Ah Da was standing upright on the bow of the boat with his bare feet at the moment. The clothes on his body are hunting and hunting at high speed as the passenger ship divides the waves and breaks the ice.
However, how can I be in the mood to appreciate his appearance now
This place is not like an underwater river in an ice cave. The water surface is full of jagged and hideous ice cones. If you accidentally stumble and fall off the bow, you will definitely end up with a sword!
Rapp half-kneeled behind the railing of the bow, and kept pulling his shoehorn with his hands, trying to drag him back from the bow!
But Ah Da, actually didn't move, and the anxious Rapp was almost crying, turned his head to me, crying, and asked for help: "Little boss, come and persuade this brother..." (End of this chapter)
