In the dark passage, we can only rely on the eye of heaven to see where the stone steps under our feet lead, Gu Tan and Shangguan Jin disappeared at the end of the passage in the blink of an eye, and here, the master is still supporting me, walking down little by little. I don't know how long I walked, but I only heard an inexplicable sound of gurgling water in front of me. At the same time as I heard this voice, a trace of cold air blew in my face, and Master suddenly grabbed my arm and whispered, "Be careful! The front may be the third vault! ”

"Master, Gu Tan and they have disappeared without a trace, and they must have reached the third secret vault. We should hurry, if we take two steps too late, we might let them get ahead of us! ”

I said worriedly, but at the moment my arms are still a little painful, even if I encounter any more danger, I am afraid that I will not be able to meet the enemy for the time being. Therefore, I was worried that I would slow down Master's journey, so that Master Gu Tan and his apprentice would get ahead of us.

"Don't worry about them, and don't worry, the four-fold vault has its own characteristics, and it's not like they can pass through it, it's good that they don't stay in the third-tier vault and wait for rescue!"

As he spoke, Master suddenly became nervous and pulled me anxiously, "Slow down! There seems to be no road ahead! Hearing Master's words, I hurriedly stopped, and Master walked around me and walked slowly. After a while, but seeing Master standing motionless at the exit of the passage in front of me, I frowned, walked quickly to Master, looked around, and immediately took a step back.

"This ...... How could this be a cliff?! ”

Looking at the extremely steep underground cliff beneath my feet, and the gray mist rising from the cliff, I felt like my heart was going to jump out. It stands to reason that this third secret vault is at most a set of strange formations, how is it different from what I imagined? Just as I was pondering in astonishment, I only heard the master muttering to himself: "I remember that your grandfather said that there is a mountain stream in the back mountain, and after passing the mountain stream, you can go to another world, which is a place where people are not humans, ghosts, demons, gods and demons, but these five kinds of creatures are gathered, and the Maoshan faction has been in charge of the teachings for generations, and they will go to it to experience it, but the two sects of Mixian have been fighting endlessly over the years, and the position of the Maoshan faction has always been in charge of the Xianzong on behalf of the sect, and there is no real sense of the teaching. So few people know about this place! ”

"Listening to what Master said, that place that is not a human, not a ghost, not a demon, not a god, and not a demon, is it referring to the Demon Cave? And from the mountain stream, is it here? ”

I took a look around, and it was hard to determine how big it was down there, but I expected to come down from the sinkhole, first the first secret vault, and then the second secret vault, layer by layer, probably beyond the scope of Maoshan Mountain, right? Then most of this place is undoubtedly from the mountain stream as Master said.

But seeing that the master shook his head, he said, "I can't tell if this is a mountain stream or not, but after we go down, we should be able to know." It's just that this steep cliff seems to be very high, and we will look around to see if there is a convenient way to go down. As he spoke, Master walked to the left, against the stone wall, and I walked to the right, and once I left the exit of the passage, it was too difficult to find a place to put my feet on the cliff.

Just as I was struggling to move forward, I suddenly saw a huge gray snake coiled around the cliff not far away, and it stretched all the way to the bottom. Trembling all over, I hurriedly wanted to retreat, but after a moment's hesitation, I looked closely at the gray snake, which did not seem to be a gray snake, but like a kind of vine vegetation that grew underground, but this vegetation had no leaves, and was bare, and it looked like a big snake.

Seeing this, since this strange vine can extend below, it is better to follow the vine. I hurriedly shouted to Master, "Master! Come here! ”

"What's wrong?"

Master instantly came to me from a distance, followed my finger to look over, Master was stunned, and said, "This is Voldemort, you have to go very deep underground to see this kind of vine, well, this Voldemort Dragon is very strong, we can go down to the bottom through it." ”

"Master, isn't Voldemort Dragon a legendary ancient beast? How can it be a vine? ”

As soon as I said it, I felt that it was wrong, so I hurriedly corrected: "Is it the same name?" ”

"Hmm."

The master responded casually, jumped down, grabbed the branch of Voldemort Dragon, pulled it hard, and nodded slightly: "This strength is okay, enough to support the weight of two people, Ergou, you can also come down." Hearing Master's words, I gritted my teeth and moved my arms and muscles and bones all over my body, although it was still painful, but it was not so strong that I didn't have any strength at all. Immediately grabbed Voldemort's branch and slid down with the master.

After a while, we were about three zhang away from the cliff, and the gray mist around us was completely passed, and looking down, there was still more than two zhang to reach the bottom. The internal landscape of this mountain stream is simply jaw-dropping, completely like the outside world, with mountain rocks, flowing water, and papyrus growing underground, green and shining, looking full of life. What surprised me even more was that there were still lumps of small dwarf trees inside, and those dwarf trees had a strange appearance, the branches and leaves were facing upward, and the trunks were completely exposed, which was very joyful.

After a short time, when there was still a distance of more than a foot in the height below, the master instantly let go of his hand and jumped down. I slid down a little more before jumping to the ground with Master. But as soon as I landed, my feet slipped instantly, and I fell to the ground. The pain made me grin, reached out and touched the ground, only to feel that these aquatic vegetation is very soft and slippery, plus the ground is full of stones, those aquatic vegetation only grow out of the cracks in the stones, and I can't get off my feet at all, and if I am not careful, I will be deceived by the slippery ground and fall squarely.

At this time, I found that Master was walking not far away, and I hurriedly turned my head to look at the place where Master was going, that, above the stone wall, there was a water spout, and the groundwater sprayed down gathered in the stone pit at the bottom like a waterfall, and then flowed down the slope, and in the distance, a stream was formed, but not far away, it seemed to converge into a small river-like mountain stream, flowing to an unknown area.

I got up and rubbed my buttocks, then took a closer look around, the air above was obscured by a thick layer of gray mist, as if it was a gray sky, and there were mountains and rivers below, and in a trance, I had the illusion that I was in a mountain stream somewhere outside at the moment. But I know that this place is the deepest place underground, and it is also the third secret vault above the Sealed Demon Cave.

"Master, how can there be fog here?"

I asked, puzzled.

"It's not fog, it's the water rising, and it's full of life, and when the two meet, it's the fog you see. Ergou, be careful, this is always the third secret vault, I don't know what kind of predicament we will encounter next, whether it is a formation or some other mechanism, it is still uncertain, so we have to figure out the geographical environment first, and then plan to do it specifically! ”

Master kept staring at the waterhole in front of him, looked at it for a while, and then stomped all the way down the stream. I thought about it for a moment and couldn't help but ask, "Master, are we going to go all the way down this stream?" ”

"Run!"

Master was just about to open his mouth to respond to me, when suddenly, I heard a rapid shout from the depths of the mountain stream...... Yes? Is it really Gu Tan? When I saw Gu Tan running desperately towards us with Shangguan Jin, and not far behind them, there were two black behemoths closely followed.

"It's an underground mountain beast, let's hide!"

Master hurriedly shouted to me, and I hurriedly ran with Master to the top of the waterfall. Not long after, when we climbed to the top of the stone wall, and Gu Tan's master and apprentice had already come to the waterfall, at this moment, I took the opportunity to look at the two mountain beasts behind me, and couldn't help but be stunned: "Master, this, isn't this the mountain guarding beast spirit that I met in the Hundred Bird Valley before?" Right! It's the mountain guarding beast spirit, but how can there be two of them here?! ”

"Hey! Ay! Yang Yuanshan, help me again, I will remember your favor! ”

When Gu Tan took Shangguan Jin to retreat to the stone wall step by step, he inexplicably found us above, and couldn't help shouting to the master. But seeing that the master didn't respond, Gu Tan gritted his teeth, pushed Shangguan Jin up, and said, "Even if you don't save me, save Shangguan Jin, he is just a junior, and it is not enough to affect the battle situation between our two secret sects!" ”

"Ergou, quickly pull Shangguan Jin up, by the way...... By the way, pull Gu Tan up! ”

Master knows very well that my magic weapon is a divine refining whip, and such a high distance can still pull the two of them up. And only I can do it in an instant, and after saying a word to me, the master turned to Gu Tan below and shouted: "Gu Tan, don't always live the belly of a gentleman with the heart of a villain, if I, Yang Yuanshan, are really the kind of person who falls into the well, I am afraid that you will die more than ten times in my hands!" If you can remember this favor, it would be good if you didn't use some intrigues and tricks against our tantra in the future, Ergou, hurry up and save people! ”

But seeing that the two black bull-like mountain guarding beast spirits were approaching Gu Tan's master and apprentice step by step, and Shangguan Jin was even more anxious to scratch and climb up, but the more chaotic it was, the easier it was to have problems. When Shangguan Jin was sure that it was safe, I hurriedly let go of the Divine Refining Whip, waved my hand and hit it, and hurriedly shouted: "Senior Uncle Gu Tan, quickly grab my Divine Refining Whip, I'll pull you up!" ”

Hearing this, Gu Tan hurriedly stretched out his hand to grab the refining whip, but at this time, the two mountain-guarding beast spirits actually attacked Gu Tan at the same time, and Gu Tan had no choice but to wave the ancient sword Mo Xie to resist. Seeing this, the master sighed lightly and flew down......
