Chapter 419

When Qingmu withdrew from Su Huilan's dream, the comatose savage on the ground just woke up.

In fact, their time in the dream was very short, at least in Alice's view, it was just a moment. She heard them say some inexplicable words about who entered who's dream. She didn't dare to ask any more, but just watched curiously.

Then, time seemed to stop. For about two or three seconds, the cave fell into silence, and even the space seemed to freeze. Alice saw Aoki and suhuilan staring at each other, motionless, like two wax statues. She felt a chill and quickly stood up and added some dead branches to the fire.

At this time, the savage lying on the ground woke up, and his open eyes were full of anger. He turned over and grabbed Alice's foot, which was adding wood by the fire.

Alice cried out in horror. She didn't know what to do. She heard a bang. The savage who was going to get up suddenly flew out, hit the stone wall of the cave and rolled down again. It seemed that she couldn't get up for a while.

She saw that the waxy green wood raised one foot just now, and the pull board on her foot was still shaking there.

Suhuilan came over, hugged Alice, kissed her cheek and comforted her, "it's okay, Alice, don't worry, it's safe here."

"I'm fine." Alice's lips turned white and her body trembled.

At the moment when the savage just held her ankle, the wild smell of body odor made her panic. She thought of Mrs. Larry. Her heart felt as bad as being caught, and then anger and hatred rose.

She stared at the moaning savage lying on the ground, and her eyes were about to burst out.

Suhuilan felt the trembling of Alice's body, which was anger from the bottom of her heart. She encouraged, "go."

Alice, with a sullen face, went over and kicked the savage hard and scolded, "beast! Beast!"

The savage on the ground got up and pounced on Alice like a trapped beast.

With another bang, the savage flew out, hit the wall and rolled down.

I don't know when Aoki was in front of Alice. His right foot was raised and the pull board was shaking on his foot.

This kick was heavier than the one just now. The savage struggled twice and vomited blood all over the ground.

Alice's courage grew stronger. She went over again and kicked the savage in the crotch. The savage had already been badly hurt. As a result, he was dying. He grinned with pain, but he had no power to resist.

Alice's face became ferocious, kicked and beat, jumped up, scratched the savage's face desperately with her nails, and shouted hysterically, but she couldn't hear what it was.

The savage was scratched black and blue by her, and there were blood marks on his face and chest. His eyes changed from anger and unwillingness at the beginning to fear.

Alice's state was close to madness. Even Aoki looked at her and felt cold. He winked at Su Huilan: "almost. Don't kill people."

Suhuilan went up and pulled Alice, but she didn't pull it away. Alice was still there frantically scratching and tearing, and even biting with her mouth, as if to revenge Mrs. Larry's suffering from the savage.

Suhuilan had to hug her and kept saying in her ear, "Alice! Alice! Stop, Alice! You can't kill him. He's still useful. We have to save Anderson!"

Alice stopped when she heard Anderson's name and sat on the ground for a long time. She turned and looked at Anderson, then threw herself into Su Huilan's arms and cried.

The savage was still alive. Alice didn't cause substantial damage to him. The real serious injury was the feet given to him by Aoki. It seemed that there were a lot of broken bones.

When Alice's mood calmed down, Aoki and suhuilan began to study how to hypnotize savages.

The natural mental force field on the island still exists, but after staying here for a whole day, Aoki was surprised to find that he has been very adapted to the existence of this energy field. Just like people in Tibet will get drunk and itch when they leave the plateau at first, but as long as they live for a few days, they will get used to the oxygen rich air on the plain.

Suhuilan obviously feels the same way. She said: "The reason why hypnosis is ineffective for islanders is that they adapt to the strong mental force field on the island, and their consciousness is not sensitive to the interference of mental force. Just like bacteria's tolerance to drugs, penicillin will not work if they fight too much. Although it is not sure whether the mental position on the island is the same as our spiritual force, I think it is the same in essence, at most ampicillin The difference between Cilin and amoxicillin. When they are resistant to ampicillin, we naturally have no effect on their use of amoxicillin. "

Although Aoki thinks there is something wrong with suhuilan's metaphor. For example, the principles of mental power and antibiotics are completely different and there is no comparability, he understands what suhuilan wants to express and admits that the current dilemma is indeed the case. If this problem is not solved, let's rely on them, together with Alice, who has no strength to bind the chicken, and Anderson, who is injured, even if the crow comes back, pat Lu and Hanran are all right. I'm afraid it's hard for them to get out of danger, let alone save Mrs. Larry.

He felt the ubiquitous mental force field, thought for a moment and said:

"You said it was a closed space surrounded by water, didn't you?"

Suhuilan said, "it's not surrounded by water, but a... Klein bottle."

"Klein bottle?" Aoki remembers that Professor Mei mentioned it.

"It was discovered by the famous mathematician Felix Klein in 1882," suhuilan explained, "You can imagine a bottle -- a vase, a wine bottle or something. Any bottle is OK, as long as it is a normal bottle with a bottom and a mouth. First dig a hole in the bottom of the bottle, and then extend the neck of the bottle. Imagine that the bottleneck is as soft as a water pipe. Bend it, insert the mouth into the bottle from any position of the bottle body, and then connect it with the hole at the bottom. That's it It became a Klein bottle.

Imagine the bottle carefully. Its mouth and bottom are connected, so it is closed. But from any point of the bottle, you can reach any point on the inner and outer surface of the bottle. That is, it has no distinction between inside and outside. A closed bottle has no distinction between inside and outside. If you put an insect into the bottle, it can easily climb out without wall piercing

Of course, Klein's bottle is actually a curved surface that can only be truly expressed in four-dimensional space. I just described it from a three-dimensional perspective, and Klein also described it from a three-dimensional perspective, but what he really described is a four-dimensional thing. In three-dimensional space, its bottleneck needs to pass through the surface of the bottle and enter the interior of the bottle, that is, the bottle itself The position in the occupied three-dimensional space is occupied by another part of itself.

But if there is another dimension, it doesn't need to pass through its own body, but connect the bottle mouth and bottom through the fourth dimension. But we need to express it in the three-dimensional space of our life, so we have to make do with it and make it look like we intersect with ourselves. "

"You mean this island is a Klein bottle?" Aoki asked.

Su Huilan opened her arms and made an upward turn, saying:

"The sea outside the island looks like a plane, but it is actually a distorted space. You can understand it as rolling up, just like the bottle body of a bottle. The island is the bottom of the bottle, and the lake on the island is the hole dug in the bottom of the bottle. The bottle body composed of the ocean slowly closes into a bottleneck in the sky, and passes through the fourth dimension to connect with the hole at the bottom of the bottle, that is, the lake on the island. This constitutes the sea A complete Klein bottle was.

That's why Alice and her family will go back to the lake when they go to sea. In the Klein bottle, the inside and outside are interlinked, which is a non directional plane, and the key is the hole at the bottom of the bottle, which is the lake on the island. It is both the bottom and the mouth of the bottle. "
