Chang Ping took a deep breath and continued to ask through the intercom, "Are there any other anomalies?" ”

The head of the regiment replied: "In a deep tunnel like this, under normal circumstances, there is an echo when you speak, but if you don't speak, there is no echo at all!" ”

The four of them widened their eyes again, gasped slightly, and then glanced in, if it weren't for the daring of the artists, they would have run out!

Chang Ping said to the regiment commander on the walkie-talkie: "You observe the situation at any time, and once you find a situation that we can't find, remind us immediately!" ”

The regimental commander's voice sounded over the intercom: "Okay! ”

Chang Ping looked at the three people and said, "Let's go, let's continue, we will record the abnormal situation that happened at any time!" ”

Liu Yuanliang glanced inside: "Will there be ghosts?" ”

Li Chaonan glared at Liu Yuanliang: "Well, there is, those who specialize in arresting people surnamed Liu, especially people like you!" ”

Liu Yuanliang immediately closed his mouth. If you can't afford to provoke us, you just don't mess with it!

Chang Ping looked at Tong Tong: "Let's go, cheer up, don't take it lightly!" ”

Tong Tong nodded and turned around and continued to walk towards the cave, the four of them continued to maintain their original formation, stupid still followed Chang Ping's side, looking inside with a pair of small eyes, and sometimes shrugged their little noses to sniff.

The four of them walked to the place where they found no footsteps again, Tong Tong paused a little and continued to walk forward, everyone tensed their nerves and paid full attention to the situation around them. Among the four people, Tong Tong has the most pressure and danger, although his speed is fast enough, it does not mean that he can dodge Chang Ping. First of all, he walked in front, and Chang Ping's vision was restricted many times; Secondly, when there is danger, as long as he dodges, Chang Ping will bear the brunt of it, because his vision is restricted, he may not be able to dodge, even if he dodges, he will not dodge, because if he dodges the danger, it will befall Li Chaonan. As for Liu Yuanliang who walks behind, it is also dangerous, because no one can guarantee that there will be no attack behind him, once there is danger behind him, Liu Yuanliang will also bear the brunt, followed by Li Chaonan, but it is better than walking in the front and the back.

"Cough", Chang Ping coughed, the three of them did not react, at this time they had walked more than a thousand meters, but still did not find a new road or situation.

"Cough", Chang Ping coughed again, and this time the voice was louder than the last time, but the other three still didn't respond.

Chang Ping hurriedly grabbed Tong Tong and stopped, and the three of them looked at him suspiciously.

Chang Ping looked at the three of them and asked, "Did you hear me coughing?" ”

The three of them looked at Chang Ping suspiciously, only to see his lips move again but there was no sound.

"Can't you hear me?" Chang Ping gestured while talking, and the three of them looked at the shape of their mouths and understood what Chang Ping meant, so they shook their heads at the same time.

Chang Ping quickly became alert, and when he arrived here, something even stranger happened, not only could he not hear the footsteps, but he also didn't hear the sound of talking. Pulled down Tong Tong and pointed to the inside of the cave, pointed at Liu Yuanliang and then pointed behind Liu Yuanliang, and the two of them immediately turned around and looked behind them vigilantly.

Chang Ping picked up the walkie-talkie: "Commander, can you hear my voice?" ”

The regiment commander sitting in the command room looked at the flashing lights on the walkie-talkie in front of him, but no sound came out. But he still picked up the walkie-talkie and replied

A sentence.

Chang Ping looked at the light on the walkie-talkie and sighed, his voice was not heard by the three people who were close at hand, let alone the head of the regiment across the walkie-talkie. Putting away the walkie-talkie, he reached out and knocked on the wall, which was hard but not a sound. There should be an extremely strong sound-absorbing substance, or this stone is, or it is hidden in the stone, and it is not known what substance it is.

If it's so quiet now, something very dangerous will happen, so you have to be very vigilant. He pulled Tong Tong down and squeezed forward from the side, Tong Tong grabbed him with his hand and shook his hand and pulled him behind him.

Chang Ping pointed at Tong Tong with his eyes and then pointed ahead, Tong Tong nodded knowingly, and then walked forward cautiously.

No one should take this lightly at this time, because the slightest mistake can take the life of a teammate.

Step by step, Tong Tong was already engrossed in his gaze ahead. Stepping on the stone slab, a spear flew out and hit Tong Tong directly, for Chang Ping's safety, he did not dodge but raised his hand to hit it.

"Bang", the spear was missed, hit the wall and then bounced to the ground. Then the second spear flew out again, and Tong Tong shot down again, one after another, without shooting everyone to death.

Tong Tong kept knocking down spears, and the nerves of the three people behind him had collapsed to the extreme. Be alert to the dangers around you.

"Teng", a thick spear shot at Tong Tong, Tong Tong slapped it with a palm without hesitation, Tong Tong's body staggered and his arm hurt, he didn't expect the power on the long hair to be so strong.

Chang Ping pulled down Tong Tong and took his place. At this time, a spear shot out again, and Chang Ping put the internal force into his hand and slapped his palm on the spear.

"Bang", although there is no sound, the sound is felt. Chang Ping smashed on the cave wall. "Click", the shaft of the spear breaks. A hole appeared in the wall of the cave, and the arrow shot out of the hole and shot at everyone, and all four people lay on the ground, and the arrow shot into the opposite wall of the cave. It's just a blink of an eye, and if you slow down, you'll be shot into a hedgehog.

As soon as he lay down, a spear shot out against the ground. "Hah!" Chang Ping roared and smashed his fist on the shaft of the spear, the tip of the spear was only a millimeter away from his nose, and if he moved a little slower, his head would be shot through.

The spear disappeared, the tip of the arrow disappeared, and the regiment commander and others held their breath as they looked at the picture on the screen.

"Whew", everyone breathed a sigh of relief, and those who had not experienced it felt like they had walked around the edge of death.

The four men got up from the ground, and they felt a palpitation at the broken spears and arrowheads. Chang Ping picked up the tip of an arrow, didn't bother to look at it more, and stared at the hole again. Round after round of attacks were like a manipulation, with no way to avoid them in front and on both sides, and they were silent. The people who came in before must have been attacked, but they couldn't find corpses and bloodstains, which was very abnormal. Who cleaned up the corpses and bloodstains?

These thoughts flashed through my mind, and it was useless to think about them at this time, the answer must be inside, so I had to go in anyway.

Tong Tong pulled Chang Ping behind him again, and he continued to walk in front and took on the responsibility of pathfinding.

The regiment commander glanced at the soldier who had just asked Chang Ping if he could do it: "Do you see it?" Do you think they'll work? ”

The soldier nodded vigorously

I thought about it for a while, if I had been attacked like that at that time, I would never have been able to dodge.

The four of them walked forward about ten meters, and there was a bend in the cave, and a hole appeared in the stone wall at the corner, where the spear was shot. Looking at the holes in the wall, I wanted to pry this place open to see the structure inside, but I just thought that I would definitely tear this place apart when I came out.

When I turned the corner, I suddenly heard footsteps in my ears, and they were so clear that I could even hear my own breathing.

Chang Ping tried to say a word: "Tong Tong, wait a minute!" The voice echoed in the small cave: Tong Tong, wait a minute! Wait a minute, a moment, a moment.

Tong Tong stopped, turned his head to look at Chang Ping and asked, "What's wrong?" ”

Chang Ping said: "I couldn't hear the sound just now, but now this place is like a megaphone, which forms a sharp contrast with the place I walked through, the mechanism there is a spear, and it is definitely not simple here, so you must be careful, even more careful than just now!" ”

Li Chaonan looked at Chang Ping: "Can you deduce what mechanism there is on this road?" ”

Chang Ping glanced inside: "There is no sound to cover up the sound of the mechanism, what is the sound here trying to hide when it is amplified?" ”

Liu Yuanliang glared and said, "Could it be poisonous gas?" ”

Chang Ping nodded: "It's also possible, so everyone put on gas masks!" As he spoke, he took out his mask and was about to put it on, "The echo here is so loud, it means that there must be a lot of space inside, and the sound must be affected by the ears, perhaps the reason for this is to confuse the public and make us unable to distinguish the direction." ”

Tong Tong nodded: "There is another thing to pay attention to, I didn't pay attention to stepping on a stone slab under my feet before, so I triggered the mechanism, so this time we must pay attention to our feet!" ”

Li Chaonan and Liu Yuanliang nodded, and Chang Ping hugged Benben: "Continue to maintain this formation, move forward, it is estimated that those who came first are more than lucky, and our main purpose now is to find the corpse and investigate whose tomb is here!" ”

Tong Tong and the three of them nodded, and the four of them put on gas masks and continued to walk forward.

The road is getting wider and wider, and the sound is getting louder and louder, the sound of breathing can be heard clearly, and after walking about 500 meters inside, the width of the cave has reached seven or eight meters, and the space is almost more than 100 square meters. What's even more strange is that the searchlight on the helmet can only shine a little more than a meter away, as if something is blocking the light.

"Stop!" The voice sounded in the empty space, as if the voice was suppressed and the voice was lowered.

Tong Tong stopped first, turned his head to look at Chang Ping and asked, "What's wrong?" ”

Chang Ping looked at Tong Tong suspiciously: "What's wrong?" ”

Tong Tong looked at Chang Ping suspiciously: "Didn't you say stop?" ”

Chang Ping shook his head: "I didn't say it!" After speaking, he looked at Li Chaonan and Liu Yuanliang behind him.

Li Chaonan and Liu Yuanliang shook their heads at the same time: "We also thought you said it!" After saying this, the four of them turned around at the same time, back to back, and looked vigilantly in front of them.

Chang Ping took out a glow stick from his bag: "Use a glow stick!" The other three took out glow sticks, broke them, and threw them out......
