When I came to the second stone stele, I was greeted by another ancient mural with rough lines. From that extremely tense picture, it can be inferred that this time the painting is showing another human catastrophe. A monster with a strange shape was slaughtering weak mortals, the monster seemed to have no fixed form, and he was constantly changing shape like a ball of mud.

In the previous frame, it was spherical, but in the next frame, it looks like a hedgehog. But no matter how it changes, this monster's method of killing people is to turn a part of its body into the shape of various sharp blades.

And in the final picture, an old man riding a one-horned three-eyed beast appeared. He held aloft a lantern with a unique shape, and a large amount of black flames erupted from the lantern to trap the monster inside.

Seeing this mural, Ao Cangfeng said suspiciously:

"Eh, isn't this the person who burns the lamp in the inverted pagoda? Could it be that the person who built this underground palace has something to do with him?"

With a snap of his mouth, Bai Xiaoyi shook his head and retorted:

"Impossible, impossible, those are all characters of myths and legends, how can they really exist? If it was really built in their time, wouldn't this underground palace have a history of four or five thousand years?"

Snorted coldly with disdain, the fox demon girl standing behind them thrust her waist and said:

"Ignorant mortals, the legends of those immortals and saints, how do you know that they are all false. Haven't you heard the old saying that there must be a reason for nothing? It's just that in their time, they may have been just ordinary people with superior abilities, but later generations exaggerated their achievements. In our Tianji Pavilion, there is a ......"

Speaking of this, Mei'er seemed to realize that she had said something that shouldn't be said, and quickly diverted the conversation and started sloppy:

"Anyway, there are so many people on the market that you haven't seen before, how can this place not be excavated thousands of years ago? Judging from the exquisite mechanisms and spells, the contents of this mural are about seventy or eighty percent true. ”

The three people present were holding their own opinions, arguing as they walked towards the next stone tablet.

And this time, the murals on the stele are even more bizarre. In the picture, three people appeared. One is the old man holding a square magic weapon in the first stone tablet, the other is the person who has just been confirmed to be able to burn the lamp, and the last one is a young man with a wheel-shaped magic weapon behind his back.

The three of them seemed to be making something on an altar, and they had inlaid five beads of different colors into the square ritual vessel. And on the inkstone-like magic weapon, this time there was an extra spoon.

When he saw this, Bai Xiaoyi exclaimed with some surprise:

"Sinan! This thing is Sinan!"

The arrogant wind and fox Meier on the side cast a puzzled look:

"Sinan, what is Sinan?"

wiped his nose, and the rogue boy said with a bang:

"Hehe, you don't know this. This Sinan was a group of monks who searched for dragon points in the Spring and Autumn Period, and the tools made from the underground magnets could identify the changes in the azimuth sensing magnetic poles. Legend has it that when the Yellow Emperor and Chiyou were fighting, there was this kind of device similar to Sinan on the chariot they were riding. ”

Nodding with a little understanding, Ao Cangfeng groaned:

"So that's the case, presumably this Sinan is the ancestor of those compasses in your Daomen, right?"

Bai Xiaoyi shrugged his shoulders as a matter of course, but the young man with the sword still asked puzzled:

"However, have you ever heard of any senior masters who used Sinan as a magic weapon?"

At this moment, the crowd fell silent again, as if they had never heard of a god-man using such a weapon in the past. The three of them, who really couldn't think of an answer, continued to look under the mural, only to see that in the picture afterward, the old man holding Sinan came to a certain mountain peak alone. Then, after passing through a huge portal, he confronted a god-man who was in the sky.

In the final scene, the god-man slapped his palm towards the old man the size of an ordinary man on the top of the mountain. And the old man raised Sinan in his hand, and the five spirit beads also flew around him.

Seeing this, the three of them were even more confused. The content of the mural is actually very easy to understand, but the three people present have never heard of the stories and legends related to it.

Bai Xiaoyi was stunned and said:

"That guy wouldn't have gone to fight the gods, would he? And then? Why can't this story be followed?"

After hesitating for a moment, Ao Cangfeng calmly analyzed:

"Wait a minute, I think the contents on these steles should be out of order, and the one we see now should be the content later. ”

As he spoke, he hurried to another stone tablet.

Sure enough, on this stone stele, a different picture appeared again. In the mural, it is a giant tree that stands on top of the sky, although it is not as connected to the world as the legendary Jianmu, but it also has a miraculous effect that covers the sky and the sun. Many weak mortals worshipped the ancient tree below, and the giant tree, which seemed to be a god, was actually using his rhizome to suck the essence of some living people underground. In the next picture, the Burning Lantern Daoist and the old man holding Sinan appeared again, and they joined forces to eradicate the ancient tree.

The three of them hurried to the next stone monument to watch. This time, there is a big difference in the content of the mural. Neither the old man who used Sinan nor the person who burned the lamp appeared, but instead there was a young man with a wheel walking magic weapon floating behind his back and two crescent-shaped magic weapons in his hands. In the picture, the young man soars into the air and is fighting a stone giant the size of a mountain. In the end, the god-like stone giant was shattered to pieces by the young man, and only an earthy yellow bead hovered in the young man's hand.

On the next stone tablet, there is a picture of the three of them joining forces to fight the enemy. And this time, the enemy they faced seemed to be a woman. But the woman was covered in flames, and the whole earth was scorched by the raging fire. The three men, who were supposed to be ancient qi practitioners, used their magic weapons to trap the woman in the middle, and there seemed to be a huge demon god's phantom shrouded in the sky in the void.

Seeing this, Bai Xiaoyi guessed:

"You say, are the three people in the mural the immortals who helped the people of Kyushu to subdue the demons in ancient times?

Nodding approvingly, Ao Cangfeng said:

"I agree with you, but I can't be sure who these three men are, and in my experience, I don't seem to have heard of any legends about these three men. ”

The fox demon girl, who was too lazy to care about what the two teenagers were guessing about, and was anxious to see the next mural, ran to the front of another stone monument. But when she looked up at the stone tablet, she was stunned:

"Eh, the picture on this ......"

Hearing the girl's doubtful voice, Bai Xiaoyi and Ao Cangfeng hurried over. But what awaits them is indeed a mural that has become dilapidated.

I don't know if it was due to geological changes or what kind of erosion the stele had suffered, but the place where the murals were originally carved has fallen off a large part. It is impossible to discern with the naked eye what is recorded on this stone tablet, but from the only small piece of content, it seems that Sinan's magic weapon has been broken by someone, and then the five spirit beads originally inlaid on it flew in all directions.

After hesitating for a long time, the three of them hurriedly ran to the last stone tablet.

Fortunately, the mural on this piece is still intact, and they can clearly identify that the man who looks like a lantern burner has led many people to build this underground palace. And he seemed to have buried the piece of Sinan, who had been broken into four parts, at the bottom of the underground palace. Just above the broken Sinan, there was still a crimson orb.

After looking at the mural on this stone stele, the fox demon girl immediately shouted excitedly:

"This dungeon, it turns out that there is really a treasure hidden! What Sinan, and that bead, are all here!"

After hesitating for a long time, Ao Cangfeng said with some concern:

"However, that Sinan is already broken. Even though it used to be a great magic weapon, it is estimated that it has now lost its effectiveness. Moreover, I always felt that the bead seemed to be written on the door of the underground palace, the evil ...... that was suppressed here."

And Bai Xiaoyi, who was full of sluggishness, didn't seem to hear what the two people next to him were saying at all, he just stared at Sinan in the mural, and the whole person fell in.

Suddenly, the scoundrel boy exclaimed in surprise:

"There it is! I've figured out how to find your way down here!"
