After nearly three years of absence, we have returned to this cave, and we have a different feeling.

"Zhao Jie, are you back?" the young man who struck the gong looked surprised when he saw us, and then smiled.

"Okay, you kid heard that he is now the village chief?" Uncle Wang smiled and patted the young man who struck the gong.

"It's all about everyone's trust. The gong striker smiled.

Next, we learned about the recent situation of the village from the young gong beater, and found that the village is now full of waste.

Part of the ruins of Xiayang Village is used as a vegetable garden, and the other part has been developed into a tourist area, which is about to be completed and has not yet opened.

Shangyang Village has become an expanded version of the Shangyang Reservoir, with a much larger storage capacity than the previous Shangyang Reservoir. Shangyang Village and Zhongyang Village were merged to form Shangzhong Village, and Xiayang Village and Pingyang Village were also merged to form Xiaping Village.

Originally, they planned to concentrate all the students in Zhongyang Village, but the number of students was too large for the school to accommodate, so the school in Pingyang Village became a branch school.

"By the way, you should know that there is a fortune teller in your village, right?" I asked the young man who struck the gong after chatting for a while.

"Fortune teller, of course I know, this man is so lazy to do it, we don't bother to pay attention to him. For a while, he slept for three days, so much so that we thought he was possessed by fire phosphors, and then he woke up after shaking it. ”

When talking about the fortune teller, the expression of the young man who struck the gong became extremely disgusted: "Hey, why do you have nothing to ask him?"

"Oh, it's okay, we're just asking. I smiled, "Do you know where he is now?"

"He's probably sleeping on his stomach in a corner, and the innermost room on the second floor is now his room, you can go there and have a look. ”

After the gong striker finished speaking, he left, saying that he wanted to go to see the construction of the Xiayang Village site. He is now the head of the four villages, but he is busy.

After saying goodbye to the gong ringing youth, we went to the second floor.

Uncle Wang's cave office is very luxurious, although it is built in a cave, it also has three floors, and there are many rooms on the bottom floor, and the space is also large.

The room on the second floor is relatively smaller, but Uncle Wang still ordered someone to repair a large room, which is to facilitate the reception of guests. There is only one office on the third floor.

On both sides of the corridor on the second floor, there are many small rooms, some of which have become utility rooms, with many old things of the Fourth Master, and some are relatively simple small rooms.

The fortune teller lived in the innermost small room, which was nice for him to live alone.

As soon as we entered, we smelled a sour smell and the fortune teller was sleeping on a single bed.

"How long has it been since this person took a bath?" Uncle Wang fanned the air in front of him, looking disgusted.

"Uncle Wang, he's Sister Lan's person. I smiled.

The disgust on Uncle Wang's face faded a little, but there was still a hint of dislike in his eyes.

"Who?" the fortune teller snorted and sat up slowly.

The fortune teller was an old man who looked to be about sixty years old, with grayish hair and beard and a somewhat sloppy face.

"You're back, you've been through a lot of things in the past few years, haven't you?" he was not surprised to see us, but behaved lightly.

"Yes, Sister Lan asked us to come to you. I said respectfully.

Since he is Sister Lan's person, he can be regarded as my elder, so my attitude should naturally be more respectful.

"Hmm. He hummed softly, "Looks like it's time for you to go there, but you'll need me to help you with your lessons before then." ”

"Another class?" Although I don't hate the course arranged by Sister Lan, I always feel that this course is endless.

"This is specially requested by Secretary Lan, so this lesson must be taken, but your lesson this time will be very useful, and you will be able to use it immediately. He said.

"What's going on this time?" I asked.

"The polar regions are divided into north and south, and this time you are going to the south, so we have to learn about the geography there and the survival guide!"

This is going to the polar regions?

But if you calculate it well, it's been almost three years since the last letter was opened, and Sister Lan said that the time interval between this letter opening will be a little long, and those three years should be about the same.

When I got to the poles, it was time for the next letter to be opened.

"Let's go, let's go to class. As he spoke, he walked out.

"Wait, where are we going to class?" I asked.

"You'll know when you get there, it's not here anyway. He said and walked out again.

"Let's go Uncle Wang, let's go Zixuan, let's go to class. I laughed.

"Zhao Jie, let's be serious, don't be too resistant, this is definitely useful. Old Black persuaded.

"Don't worry, I'll take care of it, because it really works. I responded.

The fortune teller led us out of the cave, over two ravines, and came to a cave.

"This cave...... Uncle Wang, this seems to be the cave where you took me to catch the ghosts. I said.

"That's right, this is it. Uncle Wang said.

"You...... You must have your intentions in bringing us here, right?" asked the old black.

"Come in with me. The fortune teller said and walked in. We're not far behind.

This time he led us down a slightly different path, only to see him come in and press one of the mechanisms, and a door opened directly in front of us.

Behind this door, there is something that I am very familiar with, and that is the octagonal cage.

"This place is called the magnetic isolation domain, where all electromagnetic signals can be cut off, mainly to avoid magnetic storms and observe the outside situation. The fortune teller said.

"Magnetic domain?magnetic storm?, can you put it in layman's terms?" I asked, turning my head.

"It doesn't matter, you don't need to understand it yet. The fortune teller walked out.

Further inside, a giant tower appeared, exactly like the one we saw in Li Qing's village.

"It turns out that there really is another giant tower that is exactly the same. Uncle Wang sighed.

"What's there, there are more than these two towers on the earth, there are many. The fortune teller scoffed.

"Also...... Many...... "The four of us asked at the same time.

"It doesn't matter, you don't need to understand it yet. "The fortune teller led us on our way to the tower.

This time he had a different route than we did last time, but he groped with his hands again, and a staircase appeared directly in front of us.

The stairs go down, which means that there are several floors below the tower.

"What is the origin of this tower?" I couldn't help but ask.

"Actually, this is not a tower, it has a central axis running through the ground, and the above and below parts are symmetrical. As far as I know, there are such buildings in the outside world, and they are still a famous attraction. ”

The fortune teller's explanations were more and more shocking, and we were speechless for a while.

"This tower, in fact, is just a small magnetic needle, which is also divided into two poles, which is used to detect the direction of the magnetic field. He looked at me again, "You don't have to understand this too much for a while, just remember it." ”

"This ......" I was speechless, I was shocked by what I had just heard.

"Alright, the tour is over, let's go to class!" said the fortune teller.

"Wait a minute, we're not in class here?" I asked.

He smiled: "What do you think, how can you take classes in such a place." ”

He said as he walked back.

Guan Zixuan and the others glanced at each other, and we all showed a stunned expression.

It turned out that we were just here to visit.

However, it also explained some of the doubts in my mind, and although I didn't fully understand it yet, I had a hunch that I would understand it soon.

"The fortune teller's explanation just now shows that the mountain behind Li Qing's residence does not rely on these things to generate energy, I'm afraid that energy really appears out of thin air!" Lao Hei said.

"Old Black, you know that this is terrifying?" I replied lightly.

"Think about it, how powerful should the people that Secretary Lan is afraid of be?

I think Lao Hei is usually quite sober, but today he seems to be thinking a little strangely.

Although that kind of energy is indeed very weird, Lao Wu also gave a vague explanation, I firmly believe that it must be a product of science, and it will never be a strange force.

Out of the cave, the fortune teller took us to a very secret place, where there were three small cabins, and above the grounds of the wooden houses, there was a huge green shade net, which kept the place very well hidden.

"This is where our class will be, for three days, and during these three days, I will explain to you in detail the key points of polar survival, as well as the geographical structure of the polar regions. The fortune teller said.

"Fortune teller, now you can confess your identity, right?" asked the old black.

"Actually, I'm Wen Feng. The fortune teller snapped his face as he spoke, and a handsome face appeared in front of us.
