Aoki saw that the bunch of keys discarded by the cuckoo was in the water, but it was a bit far from his cage, but closer to the cage of the mad beggar.

　　 He tried to reach out and grab it, but found that he couldn't reach it, so he got up and said to the crazy beggar: "You pick it up and throw it to me. I will help you open the cage after I go out."

　　 The mad beggar is indifferent, just like the orangutan in the zoo, holding the iron bar in both hands, looking at Aoki quietly, his eyes seem to say: "Give up, stupid humans."

　　 Aoki said it twice, and finally gave up the idea of ​​reasoning about conditions with a madman.

　　 The river began to rise slowly again. When it rose to waist depth, the water splashed in the distance again.

　　 Aoki's mind suddenly flashed, and some things that he hadn't understood all the time had a vague idea.

　　According to Du Juan, Situ activated this place, indicating that it has been abandoned for many years. This is probably not modern, because I really can't think of anyone in the modern era who would waste energy to get such a thing out in this unmanned mountain.

　　 The appearance of the Japanese seems to be able to prove this. Aoki guessed that this place was probably a prisoner of war camp established when Japan attacked southern Yunnan. This kind of pig cage was used to hold prisoners of war.

　　 If a group dream continues, even though the old dreamer dies, but new dreamers continue to join, then the entire dream can indeed be preserved. You can see the ruins of old dreams in the dream world, and the basic rules will not change fundamentally.

　　Theoretically, if people all over the world join the same group dream, the dream can continue for generations.

　　 The only thing Aoki can't figure out is that if it was really the Japanese left, it should have been abandoned for at least 70 years by now. In the past seventy years, no one has stayed here. How can this dream space and space rules be preserved? And what did the cuckoo trigger to make these Japanese appear again?

　　 When he saw the spray on the water in the distance, he remembered.

　　 There is an underground river leading to the outside world, and the water rises according to a certain rule. Every time the water rises, many aquatic animals swim by here.

　　People can dream, and animals can too.

　　 This cave is connected to the outside world, not only fish in the water, but also mice, snakes, toads, tortoises, spiders, bats...there are so many animals in the mountains that you can't imagine.

　　The mental power of animals may not be as powerful as that of humans, but if there are enough, they can support this dream.

　　 During the seven or eighty years of desertion, it was the animals in the mountains who kept this space. This is probably what the person who designed this dreamland did not expect.

　　 The water level is still rising, and black shadows continue to swim by in the water.

　　 "Come out." Aoki said to the water not far away before the water flooded his neck.

　　 A black shadow suddenly floated on the water, and then there was a crash, and a crow flew out of the water with a fish in its mouth.

　　 "Wow~~~ Ah... my fish... 呱!"

　　 As soon as the crow opened its mouth, the little fish in its mouth fell off. It plunged into the water, and after a while it threw itself out of the water, with a bigger fish in its mouth.

　　 "If you look at eating fish again, I will be drowned." When Aoki spoke, the water had reached his chin and was about to drown his mouth.

　　 "Oh oh-you are really memorizing it! After finally coming to travel, why are you locked up?"

　　 The fish fell into the water again, but this time the crow didn't care about it, but flew towards Aoki with its wings flapping. The iron railings of the cage couldn't stop its wide wings at all. It passed through like an invisible ghost and stopped on Aoki's head.

　　 "Remember to take me with me next time I travel a long distance. I feel very uncomfortable every time I am called and drunk by you!" The crow whispered its feathers while complaining, "Unhappy! Unhappy!"

　　 "Well, if you don't like the trouble of flying, I can consider taking you." Aoki said, pushing the cage door and walking out.

　　 "Flying by plane? Why do you have to fly by plane every time? You can't take a train or anything else? Why do you have to force the crow to fly by plane?"

　　 "The same goes for crows on the high-speed rail."

　　 "Oh, okay, okay, what you say is reasonable." The boss of Mei looked at the surrounding environment, "What is this place? Oh, it seems...a bit strange..."

　　 "Wait a while you will see something stranger."

　　 Aoki rose from the water, put his hands in his trouser pockets, stepped on the surface of the water, and walked slowly toward the depths of the cave. The pull board tapped and slapped the water surface, splashing water all the way.

　　 The crazy beggar in the cage next door looked at them with wide eyes. When the water level flooded his nose, he took a sharp sip of water, only to remember to grab the iron bar on the top of the cage, lift his head from the water and cough violently.

　　...

　　 "How come you were put in a cage?" the crow asked.

　　 "This is a group dream." Aoki said.

"What? A group dream? A lot of people's dreams? Oh oh~~~" The crow turned on Aoki's head and looked at the iron cage behind him, "It doesn't matter. I mean the way you are in the cage. Like... uh... like a gorilla... hahahahaha!"

　　 The crow couldn't help laughing.

　　 "Have you eaten too well recently?" Aoki said.

　　 "Oh, you really... can't afford to make a joke at all... 呱... okay okay, I said, a group dream traps you, are you regressing?"

　　 "It must be bad practice. Have you found an excuse to run so far to pick up girls? Well, I think I have to talk to Ruhua. If I have a meal, I can consider being a spy or something."

　　 "Double-sided tape?"

　　 "Well, double-sided...what? Double-sided tape? What double-sided tape?" The crow tilted his head and thought about what Aoki meant.

　　 Aoki laughed loudly.

　　 "Where is that kid?" The crow asked again, who was quiet for a while.

　　 "What kid?"

"That's the one who wrote the diary. Wow, that diary is really touching, oh, not only touching, but also touching the book www.uukanshu.com! You see me crying, you don’t know how sad I am, I’m all I'm thin, I need nutrition, quack, I need sauce elbow to make up...quack..."

　　 The crow kept roaring.

　　 made two turns, the underground river passed under a rock wall, and the iron cage also ended here.

　　 Aoki roughly estimated that the total number of cages on this road was not less than two hundred. This is more than he expected. Even if it is a prisoner of war camp, there is no need to make so many separate cages, right?

　　 The whole cave is like a maze, one hole is connected to the next. If there is no such underground river, it is easy to get lost when walking inside. In some caves, boxes of materials were piled up with the words "dangerous" or "prohibited" in Japanese.

　　 The box was covered with dust and cobwebs. As Aoki walked by, the sound of footsteps stunned many small animals hiding in the gaps between the boxes.

　　 There was a cry for help not far ahead: "Help! Let go of me! Let go..."

　　 Then there was the laughter of a group of men: "Girl Flower, Yo Xi!"

　　 Aoki walked a few steps quickly, around a large rock pillar, and saw in another cave, four or five Japanese soldiers were pressing the cuckoo on the ground and stripping her clothes.

　　 The hole is not big, but it is connected to a larger cave. There was a fire, and there was an iron pot on the fire. Seven or eight Japanese soldiers were sitting around the fire talking and laughing.

　　 "Hey, move fast, we have to play." A soldier shouted at the cave here.

　　 "Ah, you should tell them to be lighter, don't play with people to death."

　　 "Just wait slowly!" A Japanese soldier here who was taking off his pants responded.

　　 "Don't worry, none of them can last a minute."

　　 The Japanese soldiers in the cave over there burst into laughter.
