The picture came back to me, and I was faced with two choices, one was to go back and the other was to continue to dig deeper and find the source of that metallic vibrato.

Driven by curiosity, I wanted to know what secrets were hidden in the deepest part of this forest, or the deepest part of this empty place, that were not recorded in ancient books.

I don't know how far I went, but the dull sound became more powerful, and it would sound every once in a while, and each time it was as if someone was hitting the chest with a giant hammer.

Even when I didn't use all my internal strength, my face still became pale and colorless, and my steps staggered, and the sound was like a kind of magic spell, disturbing my own mind and perception, so that at this time, as long as I had thoughts, it was to explore deeper.

The further you go, the more scarce the trees become, and the more dilapidated and dilapidated ancient buildings become, but unlike the ruins, this place is not dead.

On the contrary, the abundance of aura here is amazing, and even though I am a mortal body now, I can still feel it.

Other than that, it has a lively feel to it, but I know it's definitely not as simple as it seems.

The aura is abundant, giving people a sense of vitality, if this is the case, Fang Yuan should be full of trees, lush grass, and there are birds and beasts inhabiting here, but there is no here, the trees are scarce and pitiful, and the condition of the ruins just now is almost the same.

"Knock ......"

Another dull sound sounded, and I climbed a high mountain and looked ahead, and the "deepest" part of the mountain forest was not far ahead.

It can be seen that a piece of ancient buildings is densely packed and has a panoramic view, although all of them have collapsed and become ruins, but they still cover up the magnificent momentum, and you can imagine the grandeur of the year.

What surprised me even more was that in the center of the endless complex of buildings, there was a volcano that seemed to be as high as the sky.

There was a terrible scene of boiling magma boiling and spreading down in the circular mountain pass, and even the sky above was already fiery red, and you can imagine that the temperature there was terrifying.

Endless complex of magnificent ancient buildings, surrounded by a volcano...... It's weird.

These have never been mentioned in ancient books, has it been deliberately erased, or did the ancients not know that there would be such a scene in the deepest part of this dragon vein?

I choose to believe the former, because the ancient books record this dragon vein is only a few words, but it mentions that there are "things" that have been suppressed under this dragon vein.

Beneath the dragon veins, the ancient and ruined ruins, the volcanoes, the abundance of aura, the dead silence, and the skull that struck me just now...... All of this seems to be unrelated, but if they are connected, it is enough to make people think about it carefully.

I suspect that there used to be an extremely prosperous sect of immortal cultivators here, and they once again suppressed some unspeakable "things", but then they encountered an invincible catastrophe, causing the entire sect to collapse and disappear in the eyes of the world.

But there are still too many loopholes in this speculation, if there is really such a heyday force that opened a sect in the dragon vein, and helped the human race suppress an extremely powerful "thing", why has there been no record of this sect in the ancient books of all dynasties, or recorded their merits?

It must have been a dusty history, it must have happened, maybe it was a natural disaster, maybe it was a war on a large scale, it was too mysterious here, and there were so many mysteries in it that I couldn't think about for a while.

Suddenly, an incredible picture appeared in my eyes, and then boiling magma surged, and in the circular crater, there was a large bell with a whole body rising and falling, and from time to time.

The crater can be more than 100 meters in diameter, and the big cyan bell is not very different from it, and the whole body is amazingly large, estimated to be one-third the size of the entire volcano.

"Knock ......"

The dull sound came again, from the inside of the volcano, or from the blue bell that floated inside the volcano.

Its whole body is radiant, and the whole body exudes the breath of ancient times, and at the same time, there are chains-like divine rays circulating on its surface, as if it is restraining it, making it impossible to leave the interior of the volcano.

At this time, my eyes were attracted by another place, in the complex of buildings at the foot of the volcano, a five-meter-long bird, the whole body of blue light flashing, there are arcs of electricity around its body, this is a strange beast that has long been gradually becoming a demon, can be at the foot of the hot volcano, its strength is naturally terrifying.

It reigns supreme in the ruins of the building, and no other creature dares to approach it.

Of course, it is not the only demon beast here, as far as the eye can see, there are nearly thirty demon beasts scattered among the ruins of other buildings.

There is a body of two meters long, the shape is like a centipede, there is a pair of silver wings on the back, the whole body seems to be cast with a layer of silver, the body is like a cow, the head is like a lion, there is a cyan animal hair, and the body is the size of a hill......

All of them are existences that have been cultivated for a long time and have profound Taoism.

If it was before my mana was sealed and I was demoted to the mortal world, I would probably be able to fight with them with my natural immortals, but don't think about it now, if I want to compare myself with these demon beasts with the body of a mortal, it's not that my brain is sick, it's impatient.

Nearly thirty such terrifying demon beasts are entrenched here, which is enough to show the terrifying depths of this dragon vein, they have surrounded the volcano, and they are watching the blue and gloomy bell that is constantly rising and falling in the mountain pass.

And at this time, I also noticed the skull that had just attacked me, and it was also parked in the ruins of a building, as if waiting for something.

"Lie down! That's ......"

It was only then that I noticed that I had overlooked a place where there was also a figure looming above the volcano, a humanoid creature two meters tall, with its arms covered in dense purple scales, shining brightly in the light of the rolling magma.

To his left, however, stood a beautiful "maiden", who had no arms, but instead had a pair of wings as white as snow, and her golden hair shone like gold threads.

And among them there was a large snake, to be precise, it was a dragon with two horns and a whole body covered with metallic scales.

The snake will turn into a dragon in five hundred years, and in another five hundred years, it will be able to give birth to a dragon bone and cultivate into a dragon after a thousand years of success, this guy will have more than a thousand years of Taoism, to say the least.

Among these three, except for the dragon, the other two are all innate demon spirits who do not need to be cultivated, they should all be big demons from the demon world, and their Taoism is far above me, even if I don't turn into a mortal body, it is estimated that it is enough to fight with them.

"Isn't it...... And also? Looking at the other place, I was shocked again, not far from these three big demons, there was also a humanoid man about two meters high, extremely burly, with a pair of inky black horns on his head, and the demonic energy exuded by this person was several times more than the other three.

At the same time, there were also figures flickering on the other side of the crater, and there were six old men with white hair and beards, who were real human beings, of course, not the kind of mortals who practiced martial arts, but cultivators who had set foot on the path of cultivation.

Judging from the aura emanating from their bodies, they should all be elder-level figures in the sect, not much worse than those big demons.

At first glance, the positions of these people should also be divided into hierarchies, and the distance between the Great Demon Elder and the rising and falling blue bell on the crater is the closest.

And entrenched under the volcano are some strange beasts that have cultivated into demons, and some disciples of the Immortal Cultivation Sect, these people seem to have the same purpose, they are all here for the big bell.

"It looks like there's going to be a big battle here, and I don't know if I'm here right or wrong." I muttered in my heart, the so-called fairy fight, mortals suffer, if a big war breaks out later, the scene is absolutely unimaginable.

All forces were nervously watching the crater, where the magma was tumbling, the temperature was extremely high, and the ancient bells with glittering divine light rose and fell in it, forming a strange field, which made people feel a breath from the vast years ago.

"Knock ......"

In the crater, the dull bell rang again, and this time I had been prepared, retreating a long distance, and mobilizing all my internal strength to resist, although it was still very uncomfortable, but I managed to hold out until the bell disappeared.

"Knock......", "Knock......", "Knock"......

Before I could catch my breath, there were three muffled sounds in succession, during which there was almost no gap, and the powerful sound wave shook my internal organs with a sharp pain, and a mouthful of blood gushed out of my mouth.

At the same time, magma is surging inside the crater. Blinding golden light swept across the sky, directly turning night into day.

The magma gurgled out of the crater, and the blue ancient bell rose directly, revealing this majestic aura.

"Farewell!" I didn't say a word, just ran away, that kind of power is too powerful, even those big demon elders need to cast spells to resist, not to mention me, a mortal with no mana, if I don't run at this time, will I stay there and wait for death? Auntie, I haven't lived enough!

I rushed into the distance as fast as I could in my life, and soon there was a loud bang from behind, and the sound rushed to my eyes in the blink of an eye, like a stormy wave, and directly lifted me away, and then fell heavily to the ground.

"I didn't come if I knew it, I didn't get any benefits, but I didn't almost fall to death!" I cursed hard.

Since entering this mountain forest, I don't know how many times I have fallen, first being smashed by a dry corpse, and then being attacked by an inexplicable skull...... It's really unlucky to the extreme, it's so aggrieved!

But now is not the time to complain and scold my mother, judging from the movement just now, a big war should break out in the rear, and we must leave this place of right and wrong as soon as possible, so as not to be affected by the aftermath of their outbreak again.
