The sun gradually sets in the west. The sky finally becomes cloudless. The sun slowly loses its intense heat and becomes gradually softer. The shadows of the trees are also stretched by the setting sun, lazily dragging on the ground. Amidst the noise of the cicadas, it became increasingly quiet and leisurely.

But the three professors, teachers and students were beating wildly at the moment. They kept looking at their pocket watches. According to the professor's last record, the moment when the strange projection appeared was 6:25. As this moment gradually approached, three Everyone was staring at the tombstone. It was as if they could hear each other's heartbeats and the subtle beeping sound of pocket watches.

When the time on the pocket watch showed 6:25, there were still only mottled tree shadows on the tall white marble tombstone. The strange shadow did not appear.

6:26 minutes... 6:27 minutes... 6:28 minutes. There was still no abnormality on the tombstone. The professor really suspected that there was something wrong with his pocket watch. But how could this be possible? The pocket watch he used was from Han Dynasty. 4992B. This kind of pocket watch is specially equipped on fighter jets. It is accurate and stable and absolutely trustworthy. It is the most advanced military pocket watch. Even many senior generals in the United States use this pocket watch.

Just like that, after waiting for about twenty minutes, everything was still as usual. The three of them all felt that that kind of shadow might appear irregularly. It does not necessarily appear within a fixed time period every day.

Just when the three people were a little relaxed, they suddenly heard a student pointing to the tombstone and exclaiming: "Look, the shadow has appeared. But it seems to be the shadow of three people."

The professor and another student immediately turned their attention to the tombstone. Sure enough, three clear figures appeared on the tombstone. And above the clear figures, there was still the shadow of a stone.

After the professor finished reading, he exclaimed: "Everyone, please spread out. Go back." Before he finished speaking, the tall white marble tombstone fell down in the direction where they were standing. The three people exclaimed and hurriedly ran away. .The huge stone tablet, which was seven or eight meters high, collapsed suddenly, causing half of the valley to rumble. After it hit the ground, gravel flew everywhere and dust filled the air.

The three people ran about ten meters away. They stood there in shock, breathing heavily. All this was so unexpected. Even the instructor did not expect it. But it is no wonder. The instructor did not come to the scene in person. It's just that I heard him briefly introduce the situation in the message. Such exchanges are bound to produce various errors.

After the professor was stunned for a while, he quickly took out the telegram from his mentor and read it. Because according to the original plan, his mentor spent a lot of space in the telegram telling him how to use the shadow in case the shadow appeared on the tombstone again. .to determine the whereabouts of the Taoist priest. But what happened before him was unexpected. What to do next? The professor was really at a loss. He wanted to read the tutor's message again to see if there was anything missing. Information. Based on his understanding of the mentor, he did not believe that the mentor would misjudge.

However, the result still made the professor a little disappointed, because the information in the telegram was indeed what he had already read. No new content was found.

He folded the message in disappointment and was about to put it back in his pocket. Suddenly, the professor discovered that there was a line of words on the back of the message... because that side was already full, so this line of words could only be written. It was on the back... He had never noticed such a line on the back before. He quickly opened it and read it carefully. The line read: In case of unexpected circumstances, check the base of the tombstone.

The professor was overjoyed. His guess was not wrong. The instructor's insight was still astonishing. He briefly explained it to the two students, and the three of them began to carefully examine the base of the tombstone.

The base of this tombstone is made of granite. It is as big as a house. It is a whole piece. It is such a big piece. I don't know how it was mined and polished at that time.

The professor knocked on it with an engineering shovel. Judging from the sound, it seemed that the base was not solid. He carefully checked the fracture between the tombstone and the base. He found a black hole as big as a fist. Inside the base, a student took out a small steel hammer from the tool bag and pounded hard on the hole. Suddenly the hole became as big as the mouth of a bowl. They used flashlights to shine inside to see what was inside. There is something.

The hole was not as deep as they thought. It was only about ten centimeters to the bottom. And at the bottom, there were two compass-like things, each about the size of a palm.

The professor reached out and took out these two things, and then placed them on the stone. Two students also came over. The three of them looked at these two things carefully. They were actually two stone slabs. The stone slabs were polished extremely smooth. And There are some strange patterns engraved on it. In addition, there are some words.

The professor feels that these patterns are very similar to the "array diagrams" in military books. What exactly are they? This needs to be studied carefully after returning. Moreover, the patterns on these two stones are extremely detailed and clear. They are also decorated. The different colors look very clear and eye-catching, like two exquisite works of art.

Although there was no major discovery in this investigation, there was still some harvest. However, this place is indeed dangerous, and there are also some invisible dangers. They may suddenly appear at any time, making it difficult to guard against. So, three people I feel that I should return to Hangzhou overnight and not stay here for a moment.

They left as they said. The three people quickly packed their things and took the compass and flashlight. These were two essential things for walking back at night. Of course, the most important thing was that they stuffed the two stone slabs into their bags. .This is their biggest gain from this trip.

The sky was gradually getting dark. In the mountains, it seemed to be as dark as it was dark. Ten minutes ago, the light was okay. Ten minutes later, it was dark. The three of them had to turn on their flashlights and refer to the direction pointed by the compass. A difficult journey through the mountains.

"It's a summer day. The child's face." It changes at any time. The sky is still clear in the evening. Unexpectedly, as soon as the sky gets dark, there will be more and more clouds in the sky. It is also a bit muggy. The three of them are very worried. What if? If it rains, it will be bad. Because this is summer, when it rains, it will definitely be a thunderstorm. And if you experience a thunderstorm in the mountains, it will be too dangerous.

It was an overcast day and the night became extremely dark. If you turn off the flashlight, you will almost feel like you can't see your fingers. Only the places where the flashlight shines can be seen. The shape of the mountains in the distance and the changes in the terrain are basically invisible. It was impossible to observe at all. The three people suddenly felt very depressed and had no sense of direction at all. In other words, the range they could perceive was only the place illuminated by the flashlight.

The three people walked for more than two hours under the guidance of the compass. Everyone was shouting and panting. The water in the kettle was almost empty.

However, the three of them had a strange feeling. They felt that something was getting wrong as they walked. At this speed, they should have basically left the mountain. But why did they feel like they were still walking on the rugged mountain road, and there was no sign of coming out of the mountain? Is that right? Wrong go.

But they had been walking according to the compass. How could the direction be wrong? The three people stopped and carefully checked the compass. But nothing unusual was found. The professor frowned and thought for a while. He seemed to have remembered something. Like, he took out a pair of scissors from the tool bag, and then took out a white shirt from the bag. He used the scissors to cut the shirt into strips of cloth. The two students immediately understood what the teacher was doing. road sign.

Sure enough, during the walk, the professor would tie strips of white cloth to passing trees or taller weeds at intervals not far away. Just like that, after they walked for about forty minutes, suddenly, a The student seemed to see something on the tree next to him in the peripheral vision of the flickering flashlight. When he shined the flashlight towards that thing, he couldn't help but exclaimed: "Look at the professor's white cloth strip. It turns out that we have been circling. It's not like that. Didn't go out."

The three people quickly ran over and checked carefully. It was indeed correct. It was exactly the mark made by the professor. They had indeed been circling early. The professor realized that... the compass had failed.

There are many reasons for compass failure. For example, encountering high temperature, encountering magnetic field, etc. Is the failure caused by high temperature? Of course not; is it caused by encountering magnetic field? If the mountains in this area really have a strong magnetic field, then when you come in. Why didn't the compass fail?

He suddenly thought of those two strange slates. Yes, they must be those two slates in the bag. They caused interference to the pointer.

In this dark night, the compass failed again. They could no longer determine their location. There was no other way. They had to stay in the mountains for one night and wait until dawn. The three of them put down their bags in frustration. We found a larger stone and three people climbed up.

The three of them suddenly felt very tired. The two days of trekking and various experiences in the mountains really made them a little exhausted. And tonight, they were lost like a ghost. It was also very strange. What happened? What's going on.

However, none of them dared to fall asleep steadily, because the weather was still a bit sultry, and no one knew whether there would be sudden lightning and thunder. So, the three of them were on the boulder, trying hard to control the fatigue and fierce waves. They were sleepy. The surroundings were still dark. There were sounds of unknown animals moving in the grass. Each of them held a knife or a shotgun in their hands.

The professor still let the two students sleep, leaving him to "stand guard" alone. But this time the two students felt that the professor was too hard. So the three of them agreed to take turns to rest. Two people slept, and one person stayed awake and alert to the surroundings. Everything should be changed every two hours. The professor thinks this is a good idea.
