The demons obviously didn't expect us to take the initiative to attack, and because the demons' army had not yet arrived, in fact, in addition to the owl monsters, there were not many demons ambushed at the mouth of the canyon, and there were only dozens of human wolves and beasts.

Our seven-person team mixed among the slaves and followed Chen Biao and others and soon arrived at the mouth of the canyon, the mouth of the canyon is close to the Yin Lake, we walked to the cliff to take a look, and found that the rope that was originally hanging was still there, so a few of us immediately climbed down the rope.

The group first went down to the earth and rock field, and then climbed along the cliff wall from the earth and rock field into the karst cave on the cliff wall.

In fact, at this time, there were still many owls flying on the lake, but the owls' attention seemed to be attracted by the silver dragon in mid-air, so until we all got into the hole, we were not found.

All we need to do is go back the same way back to the arch where we met the old ghost and Long Jiansheng before, and we can get close to the Heavenly Wolf Castle without realizing it. However, due to the intricacies of the terrain inside the cave, although we had already walked it before, no one could remember the exact route, so I summoned Wuchen from the stone tablet again, and he led us back the way we came.

There was no dust, and monitor lizards and giant rats lurking in the cave avoided one after another, so we had a fairly smooth journey and almost no obstacles. But everyone is actually very uneasy in their hearts, mainly worried that the fortress will be breached by demons, Li Guo tried to contact Chen Biao many times with the intercom equipment that comes with the helmet, and wanted to ask him about the current situation of the fortress, but they could not contact him, although the military intercom equipment they used The communication distance can reach more than 20 kilometers at most, but because the terrain in the cave is too complicated, the communication distance is naturally greatly reduced. And this makes everyone even more uneasy, and they don't know if they can withstand the attack of the demons.

We wandered around the intricate cave for three or four hours before we finally got out of the arch where we had met the old ghost and Long Jiansheng before.

It was pitch black, but from a distance there were bursts of dragon groans and gunshots, and a cloud of fire could be seen faintly from the sound, and it seemed that the demons had launched an attack on the fortress, and there was a fierce battle at this time.

Li Guo called Chen Biao through the intercom device again, what people didn't expect was that this time they were contacted, and the signal seemed to be good, but it was not surprising to think about it, the location we are now and the fortress are located next to the huge Yin Lake, and there is no barrier between them, so they can naturally be contacted.

Chen Biaotong guò intercom equipment told us that the army of the Sky Wolf Castle had arrived and launched a fierce attack on the fortress they were defending, but fortunately, there was a silver dragon to help a town guard, and the demons would not be able to attack it for a while, but it was difficult to say how long it could be defended, so I hope we can sneak into the Sky Wolf Castle as much as possible.

After listening to what Chen Biao said, everyone didn't care so much, and immediately ran in the direction of the Sky Wolf Castle.

According to our previous speculation, this arch cave is only a few hundred meters away from the Sky Wolf Castle, but in order not to expose the target, no one turned on the lights, Wen Qingshan and Li Guo and I all relied on night vision devices to check the surrounding situation, but due to the limited visual range of the night vision devices, I couldn't see where the Sky Wolf Castle was, so I could only follow the black wood forward.

Kuroki originally thought that we might encounter the demon's mobile outpost, so everyone was cautious, but there were no demons along the way, and it seems that the demon sent most of the troops to the fortress, leaving the city empty, so that the mobile post had to be canceled.

We walked forward for about ten minutes when Kuroki suddenly stopped and motioned for everyone to stop.

At first, everyone thought that he had discovered the mobile whistle and clenched the guy in their hands, but after waiting for a while, there was no movement ahead.

Wen Qingshan couldn't help but ask in a low voice, "Brother Kuroki, what's wrong?" ”

Kuroki replied in a low voice, "Not far further is the end of this cliff plank road, which is connected to a stone bridge that is the castle bridge of the Sirius Castle, and beyond the bridge is the Sirius Castle. At the head of this stone bridge are wolf soldiers, and if we go any further, we are afraid that they will find out. ”

After listening to what Kuroki said, I took a closer look, and although I couldn't see clearly with the help of night vision devices, I could vaguely see two symmetrically distributed buildings, which must be the bridgehead that Kuroki said.

"So how are we going to get around it now?" Wen Qingshan asked.

Kuroki turned his head to look at the Yin Lake next to him and said, "There is only one way now. ”

"What can the Kuroki brothers do?" Wen Qingshan asked hurriedly.

Kuroki replied, "The entrance to that secret passage is just below the castle bridge ahead, and we can swim there!" ”

When Wen Qingshan heard this, he couldn't help but be taken aback: "What did you say!?" Swim past? ”

I was also shocked, because the old aconitum had told us not to go into the water no matter what, because there were terrifying man-eating water monsters in the water, and Kuroki was also born and raised here, so it was impossible not to know this, but why did he offer to swim over? Thinking of this, I asked him curiously, "Brother Kuroki, you should know that there is a man-eating water monster in this yin lake, right?" ”

Kuroki nodded: "Of course I do!" ”

"Since there are man-eating monsters in this lake, aren't we afraid of being attacked by water monsters if we swim through the lake?" I asked rhetorically.

Kuroki replied, "Don't you know that although this lake is full of water monsters, there are no water monsters in this area? ”

Kuroki's answer surprised us all, and Wen Qingshan hurriedly asked, "Why aren't there any water monsters in this area?" ”

"I don't know."

"Then how dare you conclude that there are no water monsters in this area?" Wen Qingshan asked rhetorically.

Kuroki was silent for a moment, then replied, "Because I once fell into the lake here, but I didn't encounter a water monster and survived." ”

"And this kind of thing!?"

Kuroki nodded, and told us: "Once, when we were returning to the castle from our work outside, and when we were passing the bridge, a wolf soldier beat my father with a whip in his hand, and in a fit of rage, I fought with him, and the wolf soldier was stoned to death, and I was chased by the wolf soldiers who came to reinforce me, and when there was no way out, I jumped into the lake. Originally, I thought that I would definitely be dragged to the bottom of the lake by the water monster in the lake, but what I didn't expect was that I was not attacked by the water monster. ”

Hearing Kuroki say this, the old ghost said on the side, "Maybe you were lucky enough not to run into a water monster." ”

"Nope! At first, I thought I was lucky, so I swam desperately to the shore, and when I swam to the shore, I found a corpse, and it was a highly decomposed corpse. ”

"Corpses?"

"That's right! It is not surprising that this corpse must have been an accidental slave who died accidentally, almost every day in this place, but in this yin lake, there are almost never corpses. Because as long as someone falls into the water, whether they are dead or alive, they will be immediately dragged to the bottom of the lake by the water monster. The fact that the body was highly decomposed and was certainly dead for a long time, but was still floating on the water, was enough to show that there were no water monsters in the area. ”

Hearing Kuroki say this, everyone was a little surprised.

Wen Qingshan was very puzzled and said: "Since there are water monsters in this Yin Lake, why are there no water monsters in this area?" ”

As soon as he finished speaking, there was a very majestic groan, accompanied by a sound of "gurgling" like a bulging bubble, and everyone was startled.

Li Guo asked nervously, "What was the sound just now!?" ”

The roar sounded familiar to me, it felt like a dragon's groan, but it wasn't as high-pitched as a dragon's groan, and I replied, "It seems to be a dragon's groan, but it sounds a little strange." ”

"I think it's a dragon chant, and the reason why it sounds a little strange is because it comes out of the water!" Wen Qingshan said.

"You mean there's a dragon underwater?"

Wen Qingshan glanced at Kuromu and said, "The ancestor of the Kuroki brothers said that there is a demon dragon locked in the underground underground dungeon, if the secret entrance to the underground underground dungeon is not far underwater, then the dragon roar just now is probably the demon dragon locked in the underground dungeon!" ”

Hearing Wen Qingshan say this, I suddenly had a thrill in my mind, remembering that when I encountered the water monkeys in Shen Zombie Bay, Wen Qingshan and I were able to dive and live in the Yellow Dragon Cave under the protection of the silver dragon, and when the silver dragon was diving underwater, those water monkeys didn't even dare to approach, which also shows that the water monkeys are very afraid of dragons. Thinking of this, I immediately spoke: "I know why there are no water monsters in this area, I'm afraid it is because of this dragon!" ”

"It makes sense that the monster is very afraid of dragons, and although the dragon is locked in a water prison, it moans from time to time, so that the monster does not dare to approach."

Hearing what the two of us said, Kuroki was surprised and delighted: "So, what our ancestors said is true!?" ”

Wen Qingshan nodded: "It should be true!" And if there is a dragon locked in the water dungeon, it means that the entrance to the underground dungeon is indeed nearby, and that the passage is still open. Speaking of which, Wen Qingshan turned his head to Kuroki and asked, "Brother Kuroki, do you know the exact location of the entrance to that passage?" ”
