Being shouted by Zhang Gong, Zheng Suo was also a little stunned, and he asked puzzledly: "Lao Zhang, how are you sure that someone here is making trouble?" ”

Zhang Gong saw that everyone was waiting for this answer with their eyes, but he felt that it was not appropriate to say these things on such an occasion, so he whispered in Zheng Suo's ear: "This is a long story, go back and talk about it in detail, just now I saw a dark shadow, and then the bat appeared." ”

Zheng Suo nodded and asked, "Then what do you need to do now?" ”

"You let the gun-wielding SWAT walk in the front and back of the team, your people are in the middle, and the people in the expedition team are all from the training family, so let's disperse to the front and back to take care of it."

"Based on your experience, what else could have happened ahead?"

"It's hard to say, since no one in our team has gone to the front, if the black shadow is really sure to be a person, it means that somewhere in front is connected to the outside, as long as this tomb is not in a closed state in the real sense, it is difficult to say."

"If it doesn't work, let's compress the personnel, it is convenient to adapt to the situation with fewer people, and the danger factor will be reduced a lot, so that all the team members we brought will stay, and half of the expedition team will be left."

"Agreed! Then you can arrange it. ”

According to the results of the discussion, Zheng Suo brought all the people he brought with him, except for the director of the city museum, let them go back to the hotel to wait, and the expedition team also left 7 people, and the rest all retreated to the tomb gate.

Now that there are fewer people in the marching team, it is naturally much cleaner, and Zhang Gong is still walking in front of the team, carefully observing every detail around him. After walking slowly for more than 50 meters, nothing happened anymore, Zhang Gong gradually relaxed his vigilance, so he quickened his pace and led everyone to a large cave. There was no dripping water on the roof of the cave, and Professor Chen carefully observed the surroundings, and found a series of footprints on the ground in addition to bat droppings all over the ground.

Situ Fang squatted down and gestured to Professor Chen and said, "Professor, the black shadow that Zhang Gong saw just now should be this person's, with his feet almost 42 size, and he is wearing non-slip sneakers. ”

"It seems that someone has taken the lead, and everyone is more vigilant."

As Professor Chen's flashlight followed the footprints and gradually searched ahead, four identical holes appeared in front of him, and the footprints disappeared as he approached the hole.

Situ Fang also discovered the holes with the light of Professor Chen's flashlight, and after he gestured to everyone to stop moving, he walked to the entrance of the cave lightly by himself, leaned down and put his ear to the ground to listen, and then took a few steps inside to look, and after feeling that there was no danger, he called Professor Chen and them over.

"Professor, if there is no other exit here, the person Zhang Gong saw must have slipped away from one of these four holes, and there seems to be a mystery here."

Professor Chen ignored Situ's words, he walked to several holes and looked inside: each hole had artificially dug steps, and they were all circling down counterclockwise. After pondering the meeting, he discussed with Zheng Suo, and decided to install the lights and surveillance cameras here first, and then do further detection to make the next plan.

While waiting, Situ Fang said to Professor Chen: "Professor, if it doesn't work, let's go to one of the caves first, anyway, if we are idle, we will be idle, and we will have to go into the cave sooner or later." ”

"But now that you are bare-handed, I am afraid that something strange will happen in it, and I am afraid that you will not be able to resist it."

"As long as there is no water, we are not afraid, and on land we have absolute certainty to control the situation, but we are afraid of underwater."

"Is there a way to overcome it when you're underwater?"

"Underwater, you can only rely on harpoons and diving knives, and nothing else."

"So, you guys go in first and come back when you find water, okay?"

"Okay, then we'll get ready now, and we'll be in in a moment."

After a brief communication with several team members, Situ Fang decided that he and three other team members would enter the first hole first with a strong flashlight. After they walked down the stairs in a spiral for nearly 10 meters, there was a pool of water about 5 meters in diameter below, Situ Fang put his face into the water and opened his eyes, put the head of the flashlight in the water and shone it down, the clear water was bottomless. After returning to the top, they went into the second hole, and the same was true, and after trying the other two, the results were the same, and it seemed that they had to go into the water if they wanted to advance.

Situ Fang reported the discovery of several caves to Professor Chen, and communicated his plan together, and then several people put on diving equipment, carried underwater searchlights, diving knives, walkie-talkies and other necessities, and then went into the water from the first hole. When they reached the water, they dived almost three meters deep, and the waterhole was no longer a tubular downward trend, and on the way down, a large hole appeared on the side. When they got into the hole, it suddenly became much more open, and there were many forks in the hole, and the four of them unconsciously circled around in it, and finally lost their way.

When Situ Fang sensed that something was wrong, he made a gesture to stop a few people from advancing, and after a few hard strokes with his diving knife on the corner of the side, he motioned for them to swim back. After swimming like this for a few more minutes, they were back here, completely lost.

Situ Fang saw that the problem was serious, so he gestured, motioned for everyone to disperse, and carefully looked at the environment around him, he made a mark as he advanced, but after a few minutes, they still returned to the place where the first sign appeared. He looked at the pressure gauge on his teammates' oxygen cylinders, and they were all slowly approaching the red grid, which means that in another 15 minutes or so, their oxygen will be depleted, and what awaits them is a lack of oxygen, and the final result is to slowly die under this water.

Situ Fang suddenly remembered a foreign documentary he had watched before, which said that if you get lost underwater, you can either follow the water or pick a big cave, so you can definitely get out. Here he could barely feel the current, it was a pool of stagnant water, and now they had to hope for the big passage if they wanted to get out. So he adjusted his state and began to pay attention to the cave ahead.

Sure enough, after choosing the large passage as the direction, I never went back to that starting point, but I felt like I was swimming farther and farther. In less than five minutes, their good fortune came: there was no water overhead. After Situ Fang surfaced, he breathed gently, the air was quite fresh, which meant that this place was connected to the outside. So he asked a few people to turn off the oxygen cylinders and said, "If you insist on it, now we will go along the larger underwater passage like this, there will definitely be an exit ahead, and we can get out immediately." ”
