Professor Chen looked at it with emotion, and was about to leave the spill, when the moment he turned around, the headlamp flickered rapidly, and he suddenly spotted a familiar figure: the pair of boys and girls had reappeared, sitting in the dark and watching them.

Since something happens every time he finds this pair of boys and girls, Professor Chen frowned in disgust when he saw them, as if he had seen a plague god, and he turned his head and shouted to Zhang Gong: "Old Zhang, that pair of boys and girls have appeared again!" ”

Zhang Gong, who was studying the sluice gate, was so frightened by Professor Chen's sudden shout that his subordinates trembled, and quickly walked up to Professor Chen from the side and asked, "Where are the boys and girls?" How can I not see it? ”

Professor Chen turned his head, tilted his headlamp to a point, raised the corners of his mouth, and said, "Squatting there." ”

Following the direction of Professor Chen's headlamp, Zhang Gong saw that the pair of boys and girls were sitting quietly more than three meters away.

Professor Chen said: "Every time these two children appear, something happens, and I don't know what will happen this time. ”

Zhang Gong looked at the pair of boys and girls, and was also disgusted, he tried to walk over to them, to see who they were, but he did not succeed, he had just taken a few steps, and as soon as the pair of boys and girls turned around, he ran to the back, continued to keep a distance from them, and sat on the ground and watched them.

When Chen Zhijun heard his father shouting "boy and girl" outside the flood outlet, he immediately took the camera out of his backpack. He crept down on the floodport, found the location of the boys and girls, took a picture and tested it, then adjusted the camera's exposure and compensation parameters, and then aimed at them and quickly pressed the shutter.

After a confrontation like this, the boy and the girl suddenly jumped upward, then grabbed the crack in the stone and climbed quickly, and soon disappeared into the darkness.

Professor Chen wondered: "Lao Zhang, have you seen clearly, why do I think these two children are monkeys?" They crawl and jump almost exactly like monkeys. ”

"Well, this time it's the most real, and I think they're monkeys, otherwise they wouldn't be so flexible."

"Yes, bouncing nimbly around in the cracks of the stone is not something that a man can do."

"Where does this lead? Did they come from above? ”

Zhang Gong walked to the place where the boy and girl were sitting just now, looked up at the gap with a flashlight, and said suspiciously: "No, it looks like it is naturally formed, how did they get in?" Could it be that somewhere here is connected to the outside? ”

"If it's open, why are these passages designed?"

"Could it be that it was inadvertently pierced? This kind of thing is not to mention in ancient times, here are twists and turns, the mountains are estimated to be almost hollowed out, and it is normal to break through, which is put in today's advanced science and technology, and sometimes there are break-through accidents in coal mines. ”

Professor Chen nodded and said, "Anyway, it's not good every time we see them, so let's be careful for a while." ”

After speaking, several of them returned to the front of the passage, led by Situ Fang, and each of them opened a distance of two meters and slowly walked inside. As they continued to go up, the originally wet steps under their feet slowly became dry, and after turning two corners, they were completely dry, and at the same time, the air quality was getting worse and worse, making Professor Chen and them feel difficult to breathe again.

Professor Chen was a little sweaty and felt that he couldn't hold on, so he asked everyone to sit down and rest. After taking a sip of water, he said to everyone: "The air here is a little muddy, which should be inaccessible to the outside, everyone should pay attention to adjust the frequency when breathing, and try not to breathe heavily." ”

Zhang Gong wiped his sweat and said breathlessly: "The air here will not be out of circulation, if it is really blocked, then the higher the air oxygen content will be, the lower the oxygen content of the air, we have long been hypoxic and fainted, now here is only low oxygen content, not hypoxia, so where is the front is connected to the outside." ”

"It's a good sign if it's connected to the outside, but it's not good for our goals."

"The goal? Do you mean to store the artifact? I don't think so, if there were, it would have been hidden in the secret room, the air here is unobstructed, I think it is achieved through the ventilation holes, otherwise how would the craftsmen work? Nothing is possible in an oxygen-deprived environment. ”

"Don't discuss it, let's continue to move forward after resting, and we won't know the result until we get to the front."

After a five-minute break, everyone continued to set off. After turning two more corners, the uphill road becomes a downhill road, but the further down, the better the air quality becomes, which makes Zhang Gong a little surprised, he said excitedly: "It seems that there is something in front of you that is connected to the outside, it won't be going out, right?" ”

Professor Chen looked at the state of the players in front and behind, and said loudly: "No, this should mean that we are close to the ventilation hole." ”

"It's nice to be close to the vents, at least we can breathe the air outside."

The two of them walked and talked like this, and suddenly, Situ Fang, who was leading the team in front, braked suddenly, turned around and shouted to everyone: "Professor, there is a fork in the road ahead, and the left and right sides look the same." ”

Zhang Gong hurriedly walked a few steps and came to Situ Fang, he looked at both sides and said to Professor Chen: "These two sides look exactly the same, I can't tell what the function is, and I can't tell whether it's true or false, for the sake of safety, I suggest that all the people be gathered together and go to the right side." ”

After Professor Chen looked at both sides, he replied: "It's okay, then continue to open the formation, expand the safe distance, and at the same time, tie all the people in front of you together with ropes, I'm afraid there may be a flap mechanism or something." ”

After Zhang Gong nodded, he took off his backpack, squatted down and pulled out the rope. Seeing that he was busy, Situ Fang walked into the left passage, shouted "ah", then listened carefully, walked to the right side and shouted again, and after getting the answer he needed, he came back and said to Professor Chen: "Professor, you can judge that the passage on the left is shorter and the right is longer, which side do you think we choose?" ”

Professor Chen thought for a while and said resolutely: "Trust Lao Zhang's intuition, go to the right side, go long!" ”

Situ Fang nodded, and after tying the rope handed over by Zhang Gong, the group was about to go to the right, when suddenly, the pair of boys and girls came out of nowhere, jumped over everyone's heads and ran into the passage on the left.

Zhang Gong shouted to stop Situ Fang and said, "I think they want to show us the way, let's change the route and go left." ”

Professor Chan asked, "Why did you make this judgment?" Is it because they're going that way? ”

"Yes, these two little things have a problem every time they appear, but they don't kill us, so I think we should trust them, follow them, and see what they want to tell us."

"But they affect us every time."

"Yes, but it's not fatal, is it? Wang Lianchen: I suspect that they were attacked by the two of them, why? So, I think there's a difference. ”

"Okay, then listen to you, believe in those two little things again, Situ, go to the left!"
