Tong Yan did not feel depressed because of a trip to the bottom of the water, on the contrary, in his opinion, this is also an experience.

But he was still very confused, since the Demon Emperor was not in this water, where would he be? You can't just disappear into thin air.

Out of the water, he immediately returned the way he came.

Smoothly reaching the top of the stairs from which he had come, he opened the stone door that had been re-closed.

Stepping out of the stone gate, he looked around and decided to continue to search for the whereabouts of the Demon Emperor in this stone forest composed of stone carvings and various strange stones.

Probably because he had been delayed underwater for too long, Xiong Da and Gou Er among the Seven Saints of Liushan had already come down to look for him.

As luck would have it, they soon met in the stone forest.

As soon as he saw that Tong Yan was safe and sound, Xiong Da breathed a sigh of relief and said, "Brother Tong Yan, you scared us to death." You never returned, and we thought you were in some danger. ”

Hearing this, Tong Yan smiled slightly and said, "What danger can I encounter, I wish I could bump into that old ghost of Mount Tai." It's a pity that I've been looking for so long, but I still can't find any trace of the monster. By the way, what about Brother Demon Emperor? Did he return to it? ”

Gou Er hurriedly replied: "No, he and you haven't gone up, so we came down to look for it." Brother Tong Yan, you haven't met him yet, have you? ”

Gou Er said that this is obviously a bit redundant, if Tong Yan meets the Demon Emperor, how can he be alone now?

"Second Brother Dog, I have been looking for him for a long time, but there is still no trace of him. I don't know where he is now. Well, it just so happens that you have come down too. The three of us are looking for it separately, although this cave is not small, but it should not be difficult to find it all over. ”

Although Gou Er and Xiong Da were afraid of the old ghost of Taishan, Tong Yan had already said so, and they could only do it.

The three of them immediately dispersed and searched from three directions, but they didn't know if they could find the Demon Emperor smoothly.

Tong Yan looked very carefully, he was afraid that there was any mechanism somewhere, so he accidentally ignored it. But even if he searched so carefully, after a full quarter of an hour, he still found nothing.

Where the hell is the Demon Emperor? This seems to be a mystery, but it must be solved, because it is likely to be related to the safety of the Demon Emperor.

After a while, Xiong Da and Gou Er both returned to Tong Yan's side disappointed. They all found the edge of the cave, but they still didn't see the Demon Emperor.

How could a peak powerhouse whose strength had reached the realm of heavenly immortals disappear? This is difficult to accept for a while.

"Brother Tong Yan, what should we do next? There is no trace of the Demon Emperor, and there is no trace of the old ghost of Mount Tai, are we in the wrong place? Could it be that there is some path when we came, we didn't find out? ”

Xiong Da's words reminded Tong Yan that since he couldn't find the Demon Emperor in this stone forest, he might as well start from the entrance when he came.

Thinking of this, Tong Yan immediately said: "Let's go, let's take a look at the entrance when we come." There will be some hidden passages there. ”

The three of them did not delay any longer, and immediately walked out of the stone forest quickly, and then carefully searched out along the cave.

After about five minutes, Gou Er suddenly spoke: "Brother Tong Yan, come over and take a look, could this protruding stone be some kind of mechanism?" ”

As soon as Tong Yan heard this, he hurriedly walked to Gou Er's side and immediately carefully observed the stone that Gou Er said.

The stone was indeed protruding, but it was not obvious, and it looked like a protruding stone left by the excavation of a cave.

But this stone is a little peculiar, because the exposed part is smoother, smoother than the stone wall next to it.

This smoothness must be caused by friction, and after being rubbed by people or monsters, the natural surface is smooth.

This stone is not big, about the size of an adult's palm.

Tong Yan hesitated slightly, and then reached out to touch the protruding stone. After touching it and seeing that there was nothing unusual, he slammed it inside.

As soon as he pressed this, he heard a "click", like a button, and pressed it directly to the bottom.

The sound of "click" sounded, and the entire cave immediately trembled slightly.

It felt like it shook for a moment, and then the unthinkable happened.

I saw that the stone wall where the stone was located, as if it had been hollowed out below, was slowly sinking downward, and as the stone wall sank, a crack appeared above.

The area of the stone wall is getting bigger and bigger, and the cracks are getting bigger and bigger, and in less than a minute, the original stone wall has sunk into the ground, and with it, it is a dark and somewhat damp cave.

The cave is downhill, and as you go inside, the terrain gets lower and lower, so that the stone wall just now becomes the entrance to this hidden cave.

Seeing this, Tong Yan couldn't help but breathe a sigh of relief. I see, there is a cave hidden in this cave, which is even more hidden and difficult to discover than the cave that connects the underwater world he just went.

It is said that the three caves of the cunning rabbit, if this huge cave is indeed the lair of the old ghost of Mount Tai, then this hidden cave may be its real lair.

Maybe the Demon Emperor is among them, so no matter what, Tong Yan has to go down to find out.

"Second Brother Dog, you go back first and tell the others that we're fine. Put them at ease. Brother Xiong, let's go down and have a look. ”

Hearing this, Gou Er nodded and responded, "Okay, then I'll go and inform them." But you two need to be careful. ”

Tong Yan smiled and nodded, and took the lead in raising his legs and walking into this hidden cave. Xiong Da did not hesitate and immediately followed.

As soon as the two of them stepped into this hidden cave, the special stone wall immediately slowly rose again, completely covering this hidden cave again.

Raising his legs and walking down, Tong Yan's eyes were like electricity, and he looked carefully at everything in his sphere of influence.

He wanted to see if there were any clues about the Demon Emperor, and he also wanted to confirm if this was the real lair of the old ghost of Taishan.

Fortunately, the emperor lived up to his wishes, and he saw the footprints, although they were not obvious, but they were indeed footprints.

Because it is downhill and the height above is very limited, of course it is no problem to walk, but if you use a flying one, you will inevitably hit your head.

Therefore, Tong Yan is basically sure that nine times out of ten, these footprints were left by the Demon Emperor.

The Demon Emperor has been in this hidden cave for so long, will he encounter any danger?

Thinking of this, he didn't dare to continue to slack off, and immediately quickened his pace.

I walked down for about four or five minutes, and the front suddenly opened up. Immediately after, a palace-like building came into his sight.

What he didn't expect was that on the huge stone gate of this building, there were three big characters engraved, "Nuwa Palace"!
