Squeak, squeak...

Su Changtian stepped lightly on the trestle, and the trestle that looked crumbling made a loud sound, which sounded particularly gloomy.

The wind brake eagle behind him didn't dare to approach the scope of this inner mountain for a while, as if he was afraid of something, but just stood quietly on the treetops on the side, a pair of sharp eagle eyes stared at Su Changtian who was walking, as if if he turned around and came out, it would definitely take his life.

Staring at the dark inner mountain in front of him, Su Changtian did not hesitate, but walked straight forward, there was only this in front of him, there was no way out.

The back mountain is mysterious, divided into inner and outer mountains.

Under normal circumstances, the outer mountains are just ordinary small beasts, and the first-grade demonic beasts are already rare, not to mention that these second-grade demonic beasts Fengsha Eagle can be said to be the overlords of the outer mountains.

Uchiyama is completely different, although Su Changtian doesn't know much about it, but Uchiyama's murderous reputation is prestigious, and it has been passed down from generation to generation of Su families, and it is known as the most dangerous place in the entire Su family.

There was a predecessor of the Su family's military general class who trespassed into the inner mountain without permission, and after half a month without news, the body was carried out, and it was because of such a legend that the back mountain naturally became a forbidden place for the Su family.

Slowly walking down from the other end of the trestle, a strong breath of demonic beasts came to his nose, Su Changtian's nerves suddenly tensed, he couldn't relax his vigilance just because he temporarily got rid of the pursuit of the Wind Brake Eagle, you know, the horror of the inner mountain is even worse.

"Let's find a place to stay for a while. ”

Su Changtian's eyes flowed, and as soon as his breath moved, he quickly crossed into the depths of the jungle, and the branches and leaves on the side kept rubbing against his clothes, and where he passed, the forest leaves rustled continuously, slowly becoming calmer.

He is not familiar with this inner mountain, so it is better to be cautious.

I don't know how many hours have passed, this abrasive night gradually began to fade, a trace of fish belly white slowly emerged from the sky, revealing a faint light, and the shroud of the night was about to disappear.

Under the boulder covered by a banana leaf, Su Changtian was half-leaning under the stone, the wound on his left shoulder was bandaged, and after the control of his body's force, the blood began to coagulate and no longer ooze, and his breath was always in a state of convergence, so as not to be sensed by other demonic beasts and cause disaster.

The corner of his mouth lightly held a leaf, Su Changtian was also very helpless, the reason was only because of a small beast, but now he was in this dilemma, and more importantly, he didn't know how to leave this inner mountain now, and the demonic beasts were scattered everywhere, which was really a headache.

"Next time, I still can't use that bottle of essence blood in the back mountain!"

Su Changtian muttered to himself slightly, how did he close his eyes all night, looking at the sky that was about to light up, he closed his eyes with a little peace of mind.

This closure has been closed for a long time, and Su Changtian fell asleep like this, perhaps because he was too tired.

The sun rises in the east, the sunlight hits the leaves, revealing speckled shadows, and occasionally bursts of cicadas can be heard, this inner mountain seems to have been unintruded for too long, completely in a pristine environment, isolated from the world, which may also be one of the reasons for the mystery of the inner mountain.

There was a leaf that fell on Su Changtian's hand, the tips of his left fingers trembled slightly, and under the illumination of the bright environment around him, he opened his eyes dimly, and after resting for a while, the condition in his body eased slightly.

Leaning against the boulder, he stood up slowly, straightened his clothes a little, and began to look around carefully.

From time to time, there was a beast aura all around, and Su Changtian held his breath and condensed, carefully shuttling between the trees, tiptoeing around.

"Buzz..."

A subtle buzzing sound sounded from Su Changtian's body, and he suddenly showed an extremely surprised expression, because this sound was somewhat familiar to him, it was the sound of thunder that permeated his body last time!

The last time he almost shook Su Changtian out of breath, but after entering the inner mountain this time, it seemed softer, how to describe this feeling, it may be slightly similar to the feeling of cultivating on the meteorite platform.

"What kind of force is this?"

Su Changtian listened intently, and the thunderous sound in his body was slowly transmitted between the meridians, gradually spreading throughout his body, and there was an unusual feeling.

Bathed in this strange feeling, there was a trace of feeling in Su Changtian's body, this mysterious source of thunder must be somewhere in the inner mountain.

And this force seems to be guiding him to find the source.

Even this faint power emanating from it is so pure that I don't know what its origin is.

Thoughts crossed in his mind, Su Changtian carefully felt the abnormal movement in his body, and from his gaze, he seemed to be able to sense what he had discovered, and he got up and strode away in a certain direction.

I have to say that the terrain of the inner mountain is still intricate, just after passing through this bush, a large sea of fragrant flowers appeared in front of Su Changtian's eyes, but he was not attracted by the beautiful scenery in front of him, and no one knew whether there was a hidden crisis under the beauty.

A high-pitched beast roar sounded from the depths of the sea of flowers, and Su Changtian quickly walked around when he heard it, fortunately he didn't alarm it, otherwise he wouldn't be able to leave so easily.

As the time passed through the passage became longer and longer, the feeling of the thunder sound in his body was several times stronger than before, and I am afraid that even the quite pure thunder in his spiritual sea was completely inferior to it.

Su Changtian could clearly feel that the source of the thunder was getting closer and closer to him.

Ever since he first sensed the mysterious sound, he had been a little curious, and it seemed that the mystery was about to be revealed.

Behind the boundless sea of flowers, a forest of sparse bamboo leaves comes into view, and through the gaps in the sparse bamboo leaves, you can faintly see a huge building, standing majestically in the forest.

When Su Changtian slowly approached, he found that in fact, this huge building was an ancient palace that had been sealed for a long time.

The quaint dust is filled, a tile of dark brown bricks staggered inlaid together, this majestic huge building, the bucket arches are staggered, the yellow tile covers the roof, like a golden luan palace. There are ten stone pillars side by side in front, and each stone pillar is carved with two dragons, one on top and one below, which coil and rise, soaring through the clouds and mist, and look very majestic.

This ancient hall seems to be the shadow of time, with some mystery and some danger, but Su Changtian knows best, from his internal perception, the source of the thunder is set in this ancient hall.

After a simple confirmation of the surrounding environment, Su Changtian was a little relieved, and cautiously approached the gate of this ancient hall, and the environment inside could barely be seen clearly.

The interior of the ancient hall is quite spacious, but the hall is empty, if you have to say, only in the center of the ancient hall, there is an inconspicuous small platform.

Su Changtian looked at the empty scene inside, but he didn't mean to be disappointed, because the feeling in his body became stronger and stronger, and along the wonderful source, his gaze gradually fell on the central stone platform.

I saw that although the stone platform was inconspicuous, after all, it was in the middle of the ancient hall, which may have an unusual meaning.

But take a closer look, on the stone platform, there seems to be a purple long knife, different from other weapons, the mirror-like blade is cold-cold, and the tip of the knife condenses a little cold light as if it is constantly flowing, which increases the sharpness of coolness, this is undoubtedly a good knife. The handle of the long knife is engraved with a black scripture, and the blade is deeply inserted into the stone platform, and you can clearly feel that the mysterious long knife exudes a heinous majestic thunderous aura!

"That's it!"

Su Changtian exclaimed, the moment he saw this knife, he knew that this knife was the source of the power of the thunder, and even the power contained in the thunder was far inferior to him.

How could there be such a mysterious weapon?

Just as Su Changtian hesitated, a terrifying aura that had been hidden in the ancient hall was suddenly exposed, because he paid too much attention to this mysterious weapon, Su Changtian didn't notice the changes in the ancient hall at all.

This terrifying aura instantly filled the entire ancient hall, and I could feel from it that this strength was at least comparable to that of a strong martial artist of Lin Lao's level.

I'm afraid that this mysterious beast is a well-known three-rank demonic beast!
