Listening to Gao Chao's words, Xia Qing smiled heartily, but did not speak.

The fat man looked at Xia Qing, and only then did he understand what she meant, and said helplessly: "Xia Qing, you can't do things like this!" Won't our brother help you with this, and you won't take us out? ”

Xia Qing shook his head and said: "Of course I won't do that, don't worry about this, even if you don't want to help me, but I will save you, it's just ......" Xia Qing sighed at this time and said: "It's just that I have to figure out some things, but with my own ability, I am not sure that I can withdraw from it in time, and if we miss the last rescue time, then we may really never be able to get out." ”

After speaking, Xia Qing looked at Gao Chao again intentionally or unintentionally, and his eyes were full of pleading.

Gao Chao looked at Xia Qing's beautiful appearance, and could only sigh, shook his head, and said with a wry smile: "It seems that this time we have no other choice." ”

The sun was still shining in the woods, and the three men carefully examined the tents in the camp that had collapsed, and found nothing of value in the collapsed tents.

Only the black-and-white photo was carefully put away by Gao Chao, Xia Qiu on it looked very similar to him, which has always puzzled Gao Chao, in fact, Xia Qing also cares about that photo, but she is silent, as if she is hiding something she knows.

The fat man was in charge of putting away the few remaining compressed biscuits, as well as a box of canned beef, which would be their common food for the next few days, although not much, but the energy that compressed biscuits could provide should be enough to keep them going until the day when help came.

Then the three of them briefly sorted it out, and began to search nearby, according to the information in Zhao Gang's political commissar's notes, the No. 2 tunnel should be near the advance camp, and it will not be too far, so they took the camp as the center and conducted a carpet circular search, and sure enough, at ten o'clock in the evening, they finally found a suspicious hole.

It's just that this cave entrance is still very different from the No. 2 tunnel they imagined.

It was a circular hole, but the diameter was about 2 meters, and it was covered with a lot of fallen leaves and dirt before, which was not easy to find, but fortunately the fat man weighed a lot, and when he walked on it, he collapsed the soil slope on one side of the hole, and finally discovered this place.

But at this moment, the fat man tilted his head and looked at the entrance of the cave, and said with some disdain: "Do you say that this is the legendary Tunnel 2?" How do I feel like this hole is a bit like a sewer? ”

Indeed, this circular hole is indeed too much like a sewer.

Gao Chao squatted in front of the entrance of the cave, feeling the breeze blowing inside, it was a damp, cold wind, Gao Chao couldn't figure it out, could it be that the 101 Institute just found a sewer back then?

Xia Qing observed the entrance of the cave, and finally she nodded and said, "This should be Tunnel 2, the key is not what it is used for, but where it leads." ”

Gao Chao looked back at Xia Qing and said, "Are you sure?" What if you walk in and find that this tunnel leads to a septic tank? Are we going to climb up from the pit? ”

Xia Qing glanced at Gao Chao and said: "There are many kinds of sewers, as far as I know, very ancient cities, all have very advanced drainage systems, take Pompeii and Carthage as examples, they were built two or three thousand years ago, although the ancient cities have been lost, but their drainage systems can still be used normally today, so this tunnel with a diameter of more than 2 meters must be one of the drainage systems of the ancient city of Yinshan, I believe it will not be like you said, into the septic tank of a toilet." ”

Gao Chao sighed, stood up, and said helplessly: "Even if it leads to the toilet here, I have to go in, because if we don't go in, we don't want to go out......"

Obviously, Gao Chao was still a little dissatisfied with assisting Xia Qing, Xia Qing saw it in his eyes, and wanted to say something to comfort him, but Gao Chao turned his head to the fat man and said: "Fatty, the enemy is ahead, the horn of the charge has sounded, is it still far from the day of victory?" Advance! ”

After speaking, Gao Chao was the first to light the torch and walked into the circular tunnel in front of him.

The fat man also came to his senses, and immediately responded: "Please rest assured, Captain Gao, even if there are 10,000 pits in front, I will not take a step back!" Xia Qing, I'll go first! ”

Then the fat man lit the torch and followed.

Xia Qing stood at the entrance of the cave, looked at the backs of the two people in the tunnel, and shook her head helplessly, but she did not enter the tunnel, but took out the camera on her body again, and then took a photo of the tunnel entrance, turned around again, held down the camera shutter, and then quickly turned around 360 degrees, as if to shoot the surrounding environment, and then she pressed a button on the camera, and a long antenna immediately stretched out from the camera, Xia Qing then placed the camera flat next to the hole, Then she looked up at the sky unconsciously, and then she lit the torch and hurried into the tunnel.

Outside the hole, only a camera with an antenna remained, and there was nothing special about it, except for a green indicator on the fuselage, which kept flashing at a certain frequency.

The three of them entered the tunnel, Gao Chao was at the front, and after walking far inside, he found that this tunnel was indeed a drainage ditch.

At this moment, it was pitch black in the tunnel, and there was already some stagnant water on the ground, Gao Chao had accidentally stepped into it a few times, and his shoes had already been wet, he checked the state of the stagnant water, and found that the stagnant water was not dirty, it should have flowed here recently, and the further he went, the deeper the stagnant water in this tunnel.

Gao Chao held the torch, and suddenly noticed that something seemed to be reflecting a dim light in the stagnant water in the tunnel, and he quickly bent down to check and picked up a small metal object from the stagnant water.

The fat man and Xia Qing also came to him, looked at the thing in his hand, frowned and said, "It seems that we are not looking for the wrong place." ”

The fat man looked at the thing and said, "Old Gao, this ...... Is this a cartridge case? ”

Gao Chao nodded and said: "Yes, the bullet casings of the 81 bar have been seriously corroded, and they should be more than 20 years old." ”

Then they continued inside, and found more and more bullet casings on the ground, and the fat man looked at these bullet casings and said with some horror: "Have you found a problem?" ”

Gao Chao and Xia Qing looked at the fat man, and the fat man said, "There are so many bullet shells on the ground, why don't there be a single corpse?" Even if the corpse can decompose, there should be something left, right? ”

No one answered the fat man's question, just because they knew that those who had encountered accidents in this tunnel back then were afraid that they would not even have a chance to die.
