Professor Yi looked at it carefully, the shape was cylindrical, it could be as thick as a thumb, and it was packaged in black, somewhat like a No. 5 battery, but this thing was much larger than the No. 5 battery. There is a metal wire extending from the central shaft, whether it is aluminum or other alloy material, several people can't tell. But there was a slight wobble in the hands of the spectrometer. Professor Yi didn't find out.

"Dude, where did you pick up this thing?" Professor Yi raised his eyebrows and asked.

"I smelled a burning smell, of course not plastic, and I looked down and found it in that place!" Tomorrow I walked to a depression at the door of the ammunition depot. The depression was a natural groove where dust and leaves and cement fragments had been deposited over the years. Under the strong light of Professor Yi's military flashlight, all kinds of debris in this groove can be seen at a glance. Professor Yi threw the "electronic components" he found into the compartment of his backpack, then crouched down and rummaged through the branches of the trees on the ground.

Ming Yinglong saw that Professor Yi was seriously looking for clues. So I squatted down and rummaged through it together. The half-foot-long branch in his hand seemed to be more powerful. Rummage through three screws and a nut, all the size of a penny coin. And what Professor Yi turned out, Ming Yinglong didn't recognize it, he had seen it in the radio, and it was all kinds of components on the circuit board.

"Professor, what are these?"

"Capacitors, resistors, and things like that on the circuit board of an appliance. But I've never seen such a large capacitance! ”

Professor Yi fiddled with the so-called capacitor and continued: "Just now your father said that he smelled the smell of burning, do you see if this capacitor has any traces of burning?" ”

After saying that, he helped his glasses. Ming Yinglong noticed that the glasses were glowing in the light.

"Professor, your glasses seem to be very special!"

"Are you talking about these glasses? This is my special glasses, my eyes can't see in the dark, and I have some amblyopia, so I can see more clearly when I wear it. ”

Inadvertently, Ming Yinglong saw that there was a hole on the top of the vaulted hole of the air-raid shelter~ eye, he patted Professor Yi, Professor Yi was stunned, and looked in the direction pointed by Ming Yinglong. Professor Yi stood up and found various holes at the top of the cave, and the flashlight was directly aimed at one of the holes ~ eyes, the holes ~ eyes have a diameter of about five centimeters, and this hole ~ eyes seem to be used for wiring and lighting at the beginning of the construction of the air-raid shelter.

Professor Yi swept at other contour positions, and there were holes of this size~ eyes. I understand that this is just as I thought. Didn't say anything, but continued to look at the rest of the cave roof. And nothing was found.

"That's the wiring light hole that was originally reserved. Let's go! Look further! ”

Ming Yinglong just saw a bright spot through the divergent light of Professor Yi's glasses. The uniform frequency flickered, but when he heard Professor Yi say this, he felt that it was reasonable, maybe he was dazzled. So continue to hold the torch pad later.

But he still didn't have a trace of doubt, let's go out later! It's too dark and scary. Because he really remembered that when he was a child, the skeleton of the dead man and the most terrifying dead man's skull, commonly known as the skull, were turned out of the graveyard by his friends. Ming Yinglong hurriedly stopped his thoughts of scaring himself and continued to follow.

Ming Yinghong and Yi Hua were next to each other, as if they hadn't uttered a word for a long time. Just follow the adults and move on.

"Professor! I remember my daughter dancing right in this position! ”

"Are you sure?"

Tomorrow's mind recalled, and turned around to look at the name of the warehouse above: Command Room.

"I'm sure!"

There is an extra bar under this command room than in the other warehouses, although it is not obvious, mainly because it is pitch black. If there is a lighting facility, maybe a few people's discoveries can be clearer.

After surveying the command room, Professor Yi still made no new discoveries. Ming Yinglong still inadvertently glanced at the light at the top of the cave. There is no uniform frequency of flashes, and doubts are dispelled.

As we went along, I didn't find anything unusual. Professor Yi thought as he walked, and a South China Sea cigarette case and a super-large capacitor alone could not fully prove his conjecture. When there is a bright light in the front, it means that the exit is almost there. After the five of them got used to the sunlight, they slowly opened their eyes and realized that the scene in front of them was not ordinary. It is much more desolate and secluded than the entrance when it came, and the entrance is a locust forest, and the exit is almost covered by bushes. The leaves of the trees have become part of the humus and become their own nourishment. It's still halfway up the mountain.

Ming Yinglong said: "This is the western slope of Snake Mountain, follow that path, walk along the ridge is the mountain village, here is still a few miles away from the mountain village." Because snakes are frequent here in spring and summer. Therefore, few villagers come here to herd sheep and cattle. ”

Professor Yi nodded and said, "This west is a good scenery!" Judging from the sitting direction, the feng shui here is suitable, but there are not many graveyards. It's weird! ”

"Professor, do you mean that the feng shui of this location is good and suitable for burying people?"

"That's not it, the feng shui is good, there are Yiyin houses, Yiyang houses also have them, here is suitable for Yin houses, but it can't exceed the height of this cave. It's good down the mountain, but it's not good on the mountain. ”

"And this one? It's so exquisite! At this time, Ming Yinglong thought that feudal superstition was at work.

"Haha! Feng Shui I only know the fur, look at it roughly. Professor Yi always said modestly. Ming Yinglong didn't know what he meant, and he didn't discuss it too much. Many years later, Ming Yinglong recalled his father-in-law's words, but he highly recommended them.

"I want to see the iron frame on the mountain, can you see it?" Professor Yi asked.

"Professor, there are almost no roads on this mountaintop, and the barley is tall and dense, so it is not easy to walk. If you have to go up, Xiaolong and I will clear the way for you!" When I came, I had a scythe behind me! Hey! With that, a sickle was taken out from behind him, and it was still covered with cotton cloth.

"Brother, you're really thoughtful! Go, I can't be idle, Yi Hua will give me you a shovel! ”

Yi Hua pouted and said, "Dad! You see the grass is luxuriant, what if there are snakes? This is Snake Mountain! ”

"Girl! Don't we carry tools, everyone has tools in their hands, this is called scaring the snake! ”

Tomorrow from the right side of the cave to the top, where the scythe passes, the grass barley will be swept away, no matter how dense it is. Yi Hua and Ming Yinghong carefully checked left and right to see if there were any snakes.

Not to mention, this way to the top of the mountain, the man opens the way, and the woman takes a step and pats. I really didn't find a snake. It startled a lot of birds, grasshoppers, praying mantis and other insects.

Thanks to the fact that they all wore cloth shoes, socks and long pants and long clothes before going up the mountain. Otherwise, there is a hornet's nest that is almost stabbed, but this is still a timely reminder from Ming Yinglong.

When I went to the top of the mountain, I found that this place was relatively flat, as if it had been excavated by hand. The iron frame stood alone on the ground. The underside of the iron frame is fixed with reinforced concrete. The iron shelves are at least twenty meters high, which is much smaller than the iron shelves of high-voltage lines. But there are wires on the high-voltage lines, and on this iron shelf, in addition to lightning rods, there is also a device to measure the wind speed, which moves with the wind.

Professor Yi took out the spectrometer to debug the measurement index and turned it around again and again. Strange: "Isn't this tower activated?" It shouldn't be! Could it be that your own spectrometer is broken? I tried it when I came! ”

"Professor, your compass pointer keeps turning!" Ming Yinglong fiddled with the compass.

"Bring it, I'll see!"

Professor Yi looked at the compass needle at this Tai Chi and kept turning.

"Strange! Electromagnetic waves are zero, but the magnetic field is so chaotic? ”

Professor Yi walked Tai Chi steps from east to west and from west to north. Then the soil is cleared vigorously under the feet, and then the compass is held flat with the left hand, and an object is revealed under the feet. It turned out to be a black thing, round in shape, and he touched the black thing with his right hand, and dug it out, and it was buried very deeply.

"Bring the shovel!"

Ming Yinglong handed it over, and the shovel was tightly attached to the black object.

"It's a magnet! This is what you often call a magnet! It seems to be a natural magnet! It's a big magnet. And there's more than one! ”

"Shall we dig it out, then?"

"It's better not to move! Let's hurry up, the magnetic field here will get stronger and weaker over time. Someone planted a magnet in this place, presumably for experimentation! Have you noticed any strangers coming to the mountains lately? ”

Tomorrow, recalling what he had seen and heard, as if he remembered something, said, "A year ago, there were workers from the city in the village who installed this iron frame. Does it count! ”

"Where's the last time?"

"I don't think I've heard of it!"

"Professor Yi, I seem to have seen two adults in the graveyard that night!"

"At night?"

"It's not very late, early evening! The two told me to hurry home! ”

"What kind of people are two?"

"They all wear glasses, very cultured people, about the same age as the professor!

”

"That's it! Let's go back and talk about it! It's already half past two in the afternoon! If you go back too late, I'm afraid it's dangerous! Let's go! Let's go back first. ”

"Dad! There are three people in the cemetery, you see! ”

Professor Yi turned his head to look, and there were really three people, two men and one woman. Tomorrow looked at it in a daze, and those three people didn't seem to be from the village. So he said, "They don't look like the people in the village, they look like they are dressed like people from the city." ”

"Let's go! Let's go down the mountain! Professor Yi said to go.
