I was secretly ready to summon the Silver Dragon, and if something went wrong, I would have to rely on it to deal with this group of monsters, but I didn't want to summon it too soon.

But then again, it's not that we can't withstand the attack of the owl monster without summoning the silver dragon, in fact, we still have a certain chance of winning, because the terrain we are in now is quite favorable to us, first of all, our back and the direction of the top of our head will not be attacked by the owl monster, and the space in the plank road is relatively limited, for the owl monster with a wingspan of six or seven meters, it must fold its wings before it can come to us, so that their air superiority will no longer exist.

Seeing that the group of owl monsters was getting closer and closer to us, Chen Biao shouted: "Fire!" ”

Suddenly, the gunfire was loud, and the special combat team members held carbon alloy submachine guns and fired wildly.

Only then did I see the true power of this new submachine gun, the rate of fire was really not ordinarily fast, and the powerful firepower seemed to weave an impregnable protective net, and the owl monster could not get close at all.

Quite a few owls were shot down and fell into the lake.

Everyone was fighting vigorously, but suddenly there was a high-pitched, strong, and long horn sound from a distance, and those owls seemed to have received the order to retreat, and immediately turned back and retreated.

Everyone stopped shooting, and looking at the group of owl monsters in the distance, Li Guo was very puzzled and said, "Why did these monsters run away?" ”

Wen Qingshan said: "Presumably it was the sound of the horn just now that played a role, and there was an ancient saying that the horn was called to withdraw the troops. ”

"It must be that they think that the terrain we are in now is not good for them, so they will summon the owl group back, everyone must not take it lightly, they must be looking for a more suitable opportunity to ambush us." Long Yi reminded everyone.

The group of owls faded into the darkness, and we continued along the boardwalk.

The group walked about two or three hundred meters away, and found a new situation, only to see that in the middle of the road not far ahead, there were several black shadows, which looked like something was lying there, but the strange thing was that those black shadows did not emit heat, because they were black instead of orange-red in the night vision device.

Maybe it was just a few stones, but we didn't dare to be careless, we all stopped, and Wen Qingshan whispered: "I'm afraid it's a monitor lizard, the monitor lizard is a cold-blooded animal, and the infrared thermal imaging is not so obvious." ”

But Long Yi said: "I don't think it's a monitor lizard, the monitor lizard will also emit some heat, maybe it's something else, maybe it's a trap set by the demon, everyone had better be careful." ”

We waited quietly for a while, the black shadows lying on the ground were still motionless, and it was not a way to wait like this, so Long Yi decided to go over and take a look.

The group cautiously approached, and when they were only about five or six meters away from a few black shadows, we saw clearly that the few black shadows lying on the ground were actually in human shape!

My heart suddenly tightened, and the first thing that came to my mind was Professor Dong and his party, so I hurriedly turned on the searchlight on my helmet, and with the help of the light, I couldn't help but be surprised.

In fact, it is not a human at all, but a human, a wolf, and a beast! Moreover, these human wolf beasts were also wearing dark black armor and holding long-handled axes in their hands. However, on their necks, there is a noticeable knife mark.

It's no wonder that they don't form infrared thermal imaging, presumably they have been dead for a long time.

I looked around, and found that not far from the corpses of these humans, wolves, and beasts, there was an arched door. I cautiously walked over to the arched door and looked inside, but saw nothing.

Wen Qingshan stared at several human wolf beast corpses and frowned, "These should be soldiers of the Heavenly Wolf Country. ”

"But who killed them?" I said puzzled.

Long Yi squatted down and looked at it, and said, "Almost every one of them was killed by a single sword!" He must be a master of using knives, and he is extremely fast. ”

Hearing him say this, I suddenly thought of Long Jiansheng, and immediately said, "Could it be that guy!?" ”

As soon as I finished speaking, a familiar voice came from inside the arched door: "It's not bad, it's coming so soon." ”

Everyone hurriedly turned their heads to take a look, only to see two people, one tall and one short, standing in front of the arched door, it was none other than the old ghost and Long Jiansheng!

When I saw them, I was surprised and delighted.

"Old ghost senior, why are you ......" Before I finished speaking, the old ghost glared at me and said angrily: "Do you want to ask why we haven't died yet!" ”

I hurriedly waved my hand and said, "No, no! I didn't mean that, I was asking how you guys were here? ”

"Humph! If I hadn't been here, you'd have been ambushed by these monsters. ”

"So, these wolf beasts were killed by you?" Ryuichi had a shocked look on his face.

The old ghost laughed: "Hehe! They were all killed by this kid! How can I do this! ”

Wen Qingshan hurriedly asked, "Then did you find anything?" ”

"Of course, do you think we've been in for so long! Turn off the lights above your heads, and come with me! When the old ghost had finished speaking, he turned and entered the arched door, and we did not know what he was going to take us for, but we did not ask much, and out of curiosity, we all followed into the arch.

Inside the arched door is an arched passage about three meters wide, apparently also artificially built, which seems to be very long, with the help of night vision devices, there is no end in sight.

The old ghost led us inside for about twenty or thirty meters and stopped. He walked over to the stone wall on the side of the passage and stood there fiddling with it for a while, and I was about to ask him what he was doing, when the stone wall slowly opened.

Unexpectedly, there was a secret door here, all of us were taken aback, and Long Yi hurriedly asked, "Old ghost senior, what's going on?" ”

The old ghost replied without replying, "You'll know later." ”

When the stone door was fully opened, a natural stone cave appeared in front of us, and the old ghost stepped into the stone cave first, and the rest of us had to follow him in.

Not long after all of us stepped into the cave, the door slowly closed again.

The old ghost led everyone to the depths of the cave, and on the way, Wen Qingshan asked curiously, "Old ghost senior, how did you find this place?" ”

The old ghost still said the same thing: "Don't worry, you'll know later." ”

Not only are we becoming more and more curious, but what secrets are hidden in this cave?

We followed the old ghost and Long Jiansheng through the winding tunnel, and finally came to the end of the tunnel, but we didn't find anything.

Long Yi asked puzzledly, "Old ghost senior, what are you bringing us here for?" ”

The old ghost didn't say a word, walked to the end of the cave, raised his hand and gently tapped a few times on a stone wall that looked quite smooth and flat, and after a while, he only heard a "boom" sound, and the stone wall slowly opened.

Everyone was shocked again, there was actually a stone gate inside!

When the stone door was fully opened, everyone was shocked that there was a group of people inside the door! The special combat team members hurriedly raised the carbon alloy submachine guns in their hands and aimed their guns at the people inside.

The old ghost immediately shouted loudly: "Put down the gun to Lao Tzu!" ”

With the help of night vision devices, we can only see the infrared thermal image of those people, which is just a silhouette, and we can't see their appearance clearly. Because they didn't know what the situation was, everyone didn't listen to the old ghost, and still pointed their guns at those people, and Long Yi asked in a stern tone: "Old ghost senior, what the hell is going on!?" ”

The old ghost replied, "They are not demons, but human beings like us. ”

When I heard that it was a human being, I couldn't help but feel overjoyed, and blurted out: "Could it be Uncle Dong and them!?" As I spoke, I immediately turned on the searchlight on my helmet, and as soon as the light came on, I heard the men let out a piercing scream and quickly covered their eyes one by one.

The old ghost turned his head and shouted, "Turn off the lights!" ”

I was stunned for a moment before I reacted, and hurriedly turned off the searchlight, but the moment the light was turned on, I was able to see the real appearance of those people, all of them were almost indistinguishable from wild people, their hair was almost down to their waists, and they were almost unclothed, some were wrapped in monitor lizard skins, others were wrapped in mouse skins, and in their hands, they all held tools that seemed to be iron drills or something.

Wen Qingshan, Long Yi and the others also saw the appearance of those people clearly, and everyone became more and more shocked, Wen Qingshan asked in a daze: "Old ghost senior, ...... Who are they? ”

"They are all slaves of the Celestial Wolf Country! I've been in this place for too long, and I can't stand the stimulation of the bright light! ”

"What!?" Everyone was taken aback.

The old ghost turned his head to look at those people and said, "It's better for you to tell them yourself, I'm afraid I won't be able to tell you clearly." ”

After a while, one of them spoke: "We all escaped from the Celestial Wolf Country, and we were all slaves who were originally captured here by the demons of the Celestial Wolf Nation. ”

Unexpectedly, they could still speak human words, Long Yi hurriedly asked, "What the hell is going on?" ”

The man who had just spoken cleared his throat and spoke to us.

It turned out that as early as more than a thousand years ago, when the wolf cavalry of the Heavenly Wolf Country was fighting everywhere, every time they captured a city, they would take away the young and strong men and women in the city, and the old, weak, sick and disabled would all be killed. Later, even if the wolf cavalry had disappeared, the wolf country would still send owls to kidnap people, which was one of the reasons why people often disappeared in the Lop Nur area. People thought they were buried in the sand, but they never imagined that they would be taken captive to this dark underground world.
