"You really didn't hear anything?" Gu Fengchun was a little stunned. How could he be the only one who heard such a sharp and terrifying voice?

"Nope." Ye Ya shook his head seriously and said, "You didn't hear it again?" Ye Ya asked the two A guards in the back.

"Nope." The guards replied in unison.

Ye Ya slowed down, frowned as he walked, and said, "Could it be that you are having auditory hallucinations, right?" Ye Ya is a special operations officer, specially trained in hearing, and his sensitivity to sound is very keen, if there is really such a voice, it is impossible to hear it.

Gu Fengchun shook his head: "I don't have this problem, I'm very healthy, and my mental state is good." However, Gu Fengchun also suspected that he had heard it wrong, and thought to himself: "Is it too nervous?" But then he thought of the strange voice in Cao Yunfei's diary, could it be that the voice Cao Yunfei heard was also these? Thinking of this, Gu Fengchun paid attention to the walls of the surrounding corridors, but he was very strange, Cao Yunfei's diary mentioned that there were many murals here, but he patrolled all the way, but he didn't see anything. He gently put his hand on the limestone wall, and as he walked, he wondered, what was the matter with this voice and Cao Yunfei's diary, he heard the voice, but where did the mural mentioned in the diary go? Suddenly, a feeling of emptiness appeared in the depths of his heart, and suddenly, he felt very lonely, as if he was the only one left in the world. It took him a while to come out of this depressed emotion. However, this time, the baby-like strange voice was never heard again.

While thinking about it, I only heard Ye Ya say: "Damn, what the hell is this place?" ”

As soon as Gu Fengchun raised his head, it turned out that he had already walked out of the secret passage. It was pitch black in front of me, and when I turned on the strong light flashlight and shone it out, a pillar of light was formed, which couldn't even shine on the edge, and when I looked up, it was also pitch black and endless. Ye Ya took a few steps forward and illuminated the surroundings with a lamp, and he found that there was a cliff in front of him. He turned around and looked at Gu Fengchun. They were on a protruding cliff, and there was no way out except for the secret passage from which they came. Who built such a secret passage here? Both of them had this question in their hearts, but they didn't say it.

This platform is about twenty meters long and wide, and when he approached the cliff, Ye Ya felt a little frightened. He breathed a sigh of relief when he shone the light down. This cliff is only about 20 meters high, and if you want to go down, it is not a big problem. Below the suspense is an open flat land, and when you look down from above, there are many tall stone pillars below, and they can't see the end of the light when they look in the light.

"What's next?" Gu Fengchun asked. He walked all the way and found many traces of the activities of the third archaeological team in the secret passage, but on this cliff, there was no trace of human activity.

"Go down, of course." Ye Ya replied: "Obviously, this secret passage leads to the cliff, there is no other place to go here, the only thing we can do is to go down and find out if the people of the third archaeological team are lost underneath." ”

"Do you think that's likely?" Gu Fengchun asked with a frown. It doesn't look like there has been human activity on this cliff, so how could the archaeological team get lost here? Gu Fengchun thought secretly.

"Why is it impossible?" Ye Ya asked rhetorically: "In this world, nothing is impossible, Feng Chun, in the W Bureau, everything is possible." As a guard of the W Bureau, Ye Ya accepted a lot of things that ordinary people could not agree with.

Gu Fengchun nodded. Acquiesced to Ye Ya's statement. When Ye Ya decided to do something, it was difficult to change his mind.

"D1, you go up and tell Professor Zhou about our situation and let them come down." After Ye Ya adjusted the communicator, he found that he could not contact the outside, and knew that the communication signal here was extremely poor, and the signal of the walkie-talkie could not be received. Then he took out the climbing equipment from his backpack and began to settle his position on the cliff with another guard. After fixing his position, he looked up at Gu Fengchun and said, "Fortunately, this time the preparation is sufficient, and even the climbing rope has been brought." Gu Fengchun nodded, but did not speak.

The secret passage is only about two hundred meters at most, and it didn't take long for Ah Wei to trot all the way back to it, Gu Fengchun thought to himself, if he crossed the secret passage alone, he would definitely be frightened. Gu Fengchun is not small, but he has an instinctive fear of the dark, unlike the A guards, who are very familiar with and adapted to the dark. One of the many trainings of the A Guard was to spend some time alone in an absolutely dark and sealed environment. In that kind of environment, there is no sound around at all, and there is no light at all, and it will not take long for normal people to have a nervous breakdown in this environment. But Ye Ya's record is that he only relied on clear water inside, and he persevered in it for three days and three nights before finally coming out; Moreover, in the past three days and three nights, his mind has always remained awake, and he has not even taken a nap.

After Zhou Dingxuan and the others came down, Ye Ya's mountaineering rope was also fixed, and when Zhou Dingxuan saw the cliff in front of him, he was secretly happy in his heart, and thought, "They didn't lie to me." But when he thought of what would happen below, he clenched his fist tightly, and inside the fist, the palm of which was already wet with sweat.

"Professor Zhou, we are going down to the bottom of the cliff to search, and if we don't find it, we will return along the road." Ye Ya said to Zhou Dingxuan.

"No, that's not the case anymore." Zhou Dingxuan took a deep breath and said, "We still have a new task. When he said this, Zhou Dingxuan paused: "While searching for the missing teammates of the three teams, our main responsibility is to find the entrance to the hidden city, enter the hidden city, and find the "Returning to Tibet" recorded in the ancient books. I believe this is the entrance to the Hidden City. After Zhou Dingxuan finished speaking, he took out an envelope from his personal body and handed it to Ye Ya.

Ye Ya's face suddenly became gloomy. He opened the letter and read it, which read: "Captain Ye Ya, your main responsibility is to help Zhou Dingxuan find the hidden city, and everything is subject to Zhou's arrangement." The search and rescue work is in charge of the military personnel, so don't worry, but the matter of the hidden city cannot be known to you, so you didn't know it before, don't blame it. Xie Haidong characters. There are also the signatures and seals of Xie Haidong and the W Bureau below. After Ye Ya finished reading it with a dark face, he nodded and said, "Okay, Professor Zhou, what should we do?" The most important thing for A Wei is the word "obey orders". Since the orders of his superiors are so, he must follow them.

Gu Fengchun frowned, looked at Zhou Dingxuan, and faintly felt that it was not very good. With his instincts, he knew that Bureau W must have known some of the deeper secrets here, so he would rather abandon the missing team members and focus on finding what they need. Why are these missing people abandoned? Gu Fengchun broke out in a cold sweat when he thought about it. If it can be confirmed that these more than 100 lives have suffered misfortunes, it will not be of great value in search and rescue.

Ye Ya said: It's the same as usual, I'll go down first, you one by one, come down slowly. Ye Ya looked at Liu Wensheng and saw that he had a wrinkled bitter gourd face, and knew that Liu Wensheng did not have this kind of physical strength and could climb down from a height of more than twenty meters. He looked at A Wei and said, "D6 carries Master Liu down." In this way, Liu Wensheng's bitter gourd face stretched.

Ye Ya took out a few glow sticks from his backpack, shook them a few times, and threw them off the cliff. He watched the fluorescent tube fall, silently reciting the time in his heart, and after the fluorescent tube landed, he also calculated the specific height, and said to the guards, the height is about twenty-six meters, everyone should be careful when they come down, don't be careless. With that, he threw off the rope and buckled it down quickly.

Gu Fengchun's left eye suddenly jumped. At that moment, he suddenly heard a long sigh, and then heard a faint word: "You, finally here." ”
