Cheng Ruxue said: "It's okay, don't be too nervous, I don't think the problem should be very big, after all, this is just a person's tomb, and a university scholar, it shouldn't be as dangerous as we encountered before." ”

As soon as she spoke, Zheng Xiaofeng and Dong Que looked at her, only then did they realize that she was still carrying a backpack on her back, these two people were in a panic just now, and the backpack fell in the tent, Zheng Xiaofeng gave a thumbs up and said, "Sure enough, you still think the most." ”

Cheng Ruxue smiled and said, "That's also because of you in front of me, so I have time to think about this." ”

"That's right." Zheng Xiaofeng said with a smile, "What I said just now is right, I also think that the probability of danger here is not large, anyway, let's stay here, don't move things, don't go deeper, and by the time dawn, the wolves should have gone away." ”

Dong Que looked at the time, there were still about four hours before dawn, and it was not very difficult.

Cheng Ruxue also lit a fire, and the firelight converged, and the surroundings became brighter. After observation, it was found that the space here is still quite large, and the length, width, and height are almost about fifteen or sixteen meters. It's empty, there are no furnishings, just a lot of lines on the walls, but if you look closely, you can't see the kind of murals you saw before.

The three of them cautiously walked to the wall closer to the exit, and looked at the lines, there were many characters, there were many graphics, at first glance it looked a bit like a math teacher's board book in school, or maybe it didn't look like it at first glance, it was just like that.

Cheng Ruxue said: "How do I feel that this is a bit like the derivation process of some mathematical problems? ”

She didn't say this because she could understand it, but because the other two did feel the same way.

"That's right, you look at these, it's a bit like an equation, a little bit down, like an off-line calculation." Zheng Xiaofeng also said, "This pattern like a balance may be an equal sign." ”

Dong Que said: "The equation is a bit outrageous, I heard that this thing was invented around the sixteenth century, it's a Frenchman, it seems to be called Da, yes, Wada, but this West Dremsterste is a person from the sixth century BC, with an interval of more than 2,000 years, and this time span is too big." ”

Zheng Xiaofeng thought for a while, and said half-speculatively: "You yourself said that most of this person's research results have not been passed down to the world, maybe some theorems or mathematical research methods that were only proved in later generations have already been mastered, but unfortunately they have been lost." ”

"That's possible, and that would be a great sign of the man's algebraic geometry."

A few people looked at it for a while, but in fact, they couldn't understand anything at all, it was just a novelty, Zheng Xiaofeng suddenly asked Dong Quede: "Why don't you write these down?" ”

Dong Que was stunned for a moment and asked, "Me?" What am I doing with all this stuff? ”

"Aren't you here to learn and learn?"

Dong Que couldn't cry or laugh, and said: "Big brother, I said that learning things is not learning these things, if I really want to learn mathematics, why do I go here where birds don't?" Isn't it fragrant to go to nine years of compulsory education early? ”

Zheng Xiaofeng spread his hands and signaled that I was joking.

At this time, Cheng Ruxue pointed to the farther part of the tomb and said, "Look, there seems to be another road over there. ”

The two of them looked over, blinked, and sure enough, they saw that in the center of the wall facing the exit, there seemed to be a gap that was not too big or too small for two or three people to pass through. ”

He didn't say this nonsense, the gap he was talking about was in the center, not in the middle of the root of the wall, but really in the center of the whole wall, which means that if anyone wanted to pass through there, they would have to climb to the height of two or three stories first.

"It's really weird." Zheng Xiaofeng echoed, pointing to the wall on the left as he spoke, and said, "Look, there are also over there." ”

Upon closer inspection, there were the same gaps in the same position on the wall, but the top, right, and exit sides were completely sealed. The three of them looked at each other, and suddenly thought of something together, Dong Que understood and lit a fire again.

Now the light was brighter, and the three of them walked forward slightly, and sure enough, they saw that there was also such a square gap in the center of the ground.

"It seems that there is still space down there, and this tomb is not only as big as in front of us." Zheng Xiaofeng said.

Dong Que said: "Indeed, this old brother is quite capable of tossing." ”

"But it doesn't matter how much space there is, we don't want to make trouble this time."

The three of them returned to their original places, sat on the ground, and continued to wait peacefully, everyone did not sleep well this night, but fortunately, now that there is such a "shelter", Zheng Xiaofeng said that Cheng Ruxue and Dong Que would have to sleep again, and he was responsible for watching the situation.

Cheng Ruxue originally wanted to accompany Zheng Xiaofeng, but after staying at night, she couldn't stand the sleepiness, so she had to sleep in order not to delay her legs in the future. Zheng Xiaofeng was alone, staring at his watch quietly, waiting for the time to pass minute by minute.

Almost four hours later, the hands of the watch reached six o'clock.

Zheng Xiaofeng woke up two people, and the three of them came to the exit and began to think about how to climb up.

To be honest, this tunnel is a bit high, the reason why the first three people can jump down very easily, one is because there is still a certain slope at the beginning of the tunnel, and then there are psychological factors, driven by danger, even if you jump off a building or something, it is nothing, but now the three of them can see clearly, just take two steps inside, followed by a completely ninety-degree upward path, until five or six meters later it became a little more inclined.

"What's going on, comrades?" Dong Que scratched his head and asked.

Zheng Xiaofeng said: "Actually, it's easy to do, there are three of us, one step on the other, the top person should barely be able to get to the position with a slope, and then put down the rope after going up, and pull the remaining two up." ”

"Makes sense." Dong Que said, "Then the question is, who is at the bottom?" ”

Zheng Xiaofeng and Cheng Ruxue stared at Dong Que together, Dong Que looked blue and said, "Yes, I don't ask, I dare to be an outsider." ”

After the three of them finished "discussing", Dong Que squatted in the pit, but Zheng Xiaofeng was just about to step on his shoulder, when a faint sound suddenly sounded not far behind him.

"Life~............"

"Fate! ～…………”

The three of them were stunned for a moment, and they couldn't help but hold their breath and concentrate on it, and then listen to the voice. There was no movement in the chamber, and the sound seemed to be coming from a farther distance.

"Did I hear me right? Is it 'life'? There are also people here who say Chinese? Dong Que asked in a low voice, and Zheng Xiaofeng speculated: "It can't be some kind of revenant soul or something, is it saying, 'Give me my life back'?" ”

"You've watched too many ghost movies?" Dong Que had to say, "Besides, even if it's a ghost, it tells me that this is useful?" I have never killed anyone, and the only life that will die in my hands in my life is my hundreds of millions of descendants. ”

At this time, Cheng Ruxue waved her hand and said, "Listen more carefully, is someone shouting for help?" ”

The eyes of the two of them lit up, and then they pricked up their ears, as if this was really the case.

"Someone trapped inside? Or compatriots? Zheng Xiaofeng couldn't help but understand.

"That's a coincidence." Dong Que had to say, "Then what should we do?" ”

Zheng Xiaofeng thought for a while and said, "What else can I do?" Now that you've heard it, you can't just walk away, right? ”

"But......" Dong Que looked a little hesitant, "Didn't we say we wouldn't stay here?" In case there is danger inside, maybe the three of us rookies will have to ride in together. ”

Zheng Xiaofeng sighed and said, "The reason why we came here is not only to find the truth, but also to seek knowledge, but also to train ourselves, but if we leave like this today, won't all this become a joke?" ”

Dong Quede frowned at this time, blinked, reacted for a while, and said, "Okay, you convinced me." ”

At this time, Cheng Ruxue said: "We must go to save people, but we have to be careful and do our best, I don't know why that person shouted for help, maybe what is the situation that we can't handle well, should we ......"

Without waiting for Cheng Ruxue to finish speaking, Zheng Xiaofeng suddenly grabbed the conversation and said, "Otherwise, for the sake of safety, I'll go over and take a look alone, and don't put the eggs in one basket to avoid the possibility of group annihilation." ”

Before the words fell, Cheng Ruxue's expression knew that she disagreed, Dong Que had to say: "Dude, don't make trouble, although we are afraid of death, but it will not let you be buried to this extent, you said that if something really happens to you, we can still throw you away, no matter what you do?" It's not that I have to save you, in the end, it's better to act together, at least there is a response. ”

Zheng Xiaofeng thought about it and said yes, so he didn't recklessly, the three of them made up their minds, and walked towards the opposite side together.

"Help ......" became clearer, and it seemed to be a woman's voice.

came to the bottom of the wall, the three of them followed the method just said, Dong Que had to cushion at the bottom, Zheng Xiaofeng stepped on it, and Cheng Ruxue followed up again. At a height of more than two floors, Zheng Xiaofeng used his arm strength to send the person up again, and Cheng Ruxue jumped hard and climbed to the top of the gap.

The rope fell, Zheng Xiaofeng and Dong Que climbed up in turn, and the three of them first took a fire and shone it over there, and found that it was a tomb that was almost exactly the same size, shape, and furnishings as this side.

There was no one inside, and the sound seemed to be further away, and upon closer inspection, there were also three gaps in the bottom, directly opposite, and left side of the new burial chamber.

"Good fellow, is it still a labyrinth?" Dong Que said, Zheng Xiaofeng jumped down first, stepped on the ground, and there was no danger.

Dong Quede and Cheng Ruxue followed one after another. "Help—" The voice must have been close, as if it was coming from the gap directly opposite.
