After hesitating again and again, Su Daochen still decided to find out.

With his temperament, since they have all come once, it is impossible to return empty-handed and retreat so gloomy.

Now, he was curious, and his intuition told him that there were amazing secrets buried under this red earth, and that perhaps something else might be gained.

Stepping into the black mist, Su Daochen gradually drifted away, and soon disappeared.

This black fog was very weird, and the visibility was extremely low, even with the strength of his divine sense, it could only cover three feet around his body.

Groping all the way forward, like crossing a river by feeling a stone, Su Daochen was nervous and always paid attention to his surroundings.

Fortunately, this section of the road was very calm, there was nothing abnormal, and I walked out safely.

It's just that I didn't walk a hundred steps away, and in front of me, there was a deep pit with a diameter of hundreds of meters, which was snow-white and shining.

On closer inspection, it can't help but be terrifying.

This deep pit, filled with dense and countless bones, is a mass grave!

Rao is Su Daochen couldn't help but gasp slightly.

The scale of the dead man's pit in front of him is so large and unfathomable that it is difficult to say how many bones were buried.

He was a little surprised, it turned out that those rumors circulating in the market turned out to be true!

Although he didn't know exactly what happened back then, judging from some very different body types, he found other creatures besides human races and demon beasts.

It was a very large hip bone, the size of a grinding plate, shiny and shiny, shining silver and white in the pile of bones, very conspicuous.

Su Daochen secretly thought, just a hip bone has such a specification, you can imagine how huge this creature should be when it is alive, obviously it will not be a human race.

He couldn't help but think back to the wing-like "wing bones" he had seen near the entrance to the cave.

A little comparison shows that this is from a completely different ethnic group.

He was a little difficult to calm down, who would have thought that under this barren mountain that was thousands of feet deep and uninhabited, it would be such a scene?

"There was supposed to be a big war back then.......

Carefully looking at the white bones in the deep pit, Su Daochen's eyes condensed slightly.

Almost more than ninety percent of the bones are incomplete and scattered, making it difficult to piece together the whole, which is not quite like being weathered naturally.

And he also noticed that some of the white bones were vaguely visible traces of Bingge, which were three points into the bones, which was very sharp.

These bones are different from others, relatively intact, and brighter in color, which contrasts significantly with other bones that are almost shattered.

Su Daochen nodded secretly, these white bones have been devastated by the years, and they are all well-known characters during their lifetimes, and they should be general-level figures.

At this point, he had some vague speculation that a thousand years ago, or even longer, there might have been a huge riot in this place, affecting several ethnic groups.

"Are they fighting for something? Or ......"

He naturally thought of the competition for resources, judging from the tens of thousands of bones he saw, he must have experienced a very bloody battle back then.

It's rare for so many people to be bloodied, killed and wounded, and he's inclined to fight for large resources.

Of course, all this is just his speculation, and there is no substantive basis.

However, one thing he knew for sure was that the Terrans were at a disadvantage in that battle, and the battle was very difficult.

Because, as far as the eye can see, seventy percent of the bones in the pile of bones are the bones of the human race, and the remaining thirty percent are those of other alien races.

Thinking of this, Su Daochen's heart flashed slightly, and a new puzzle suddenly arose.

Back then, the other alien races should have had the upper hand, that is to say, the Terran race was very likely not to be an opponent in that battle and faced defeat.

But the fact is that, judging from all indications, the Terran race probably did not lose that battle!

After all, for nearly thousands of years, there has been no other alien activity in this area of the Southern Regions, and there are not even some rumors and news.

It was as if it had disappeared and completely disappeared from the eyes of the world.

"Secret Realm, Barren Mountain, Iron Palace, Black Coffin, Female Corpse, Corpse Demon, White Bone ......."

Taking a deep breath, Su Daochen only felt that things were confusing, and it was getting more and more difficult.

He had too many puzzles.

For example, why did the Terrans win the final victory in that battle? Was it the strongest who made the move, or was it something else?

Where did the other aliens end up? Wiped out or gone, why don't there be legends about them in the South?

After thinking for a while, Su Daochen subconsciously remembered the sword master who was away from hatred.

Legend has it that in his later years, he lived in seclusion in the Luoxia Mountains, concentrating on enlightenment, not asking about the world, and once attracted countless people to come here, and later generations called it Sword Valley.

As far as he knew, there was no trace of that sword master, and after entering the Sword Valley, it was as if the world had evaporated, and he never appeared in everyone's field of vision again.

Many people have rumored that the Sword Master has sat down and died, otherwise it would not have been possible for thousands of years not to appear in the world, and he has not even cared about the sect where he is located.

In Su Daochen's opinion, he was not sure whether the Hate Sword Master was dead or not, but that Sword Master had indeed stayed in this secret realm for a period of time and left a legacy.

It's just that, other than that, he didn't make superfluous discoveries.

If a powerhouse of that realm died in the secret realm, he should have noticed it a long time ago, but he didn't notice the existence of special bones.

He had always had a question, and he still didn't understand it.

The Luoxia Mountains are remote and uninhabited, although they can be called full of spiritual energy, but the cultivation environment of the Sword Sect should not be bad, right?

What was the reason for the founding ancestor of the Lihate Sword Sect to give up everything and commit himself to this?

If you want to be pure, there are many places to choose from, and it is obviously not difficult for a strong sword king.

"It's getting more and more interesting."

Su Daochen murmured softly, his eyes became brighter and brighter, and he found that he seemed to have come into contact with something extraordinary.

Shaking off the complicated thoughts in his mind, he strode forward.

At this point, it is useless to think more.

If you want to figure out all this, I am afraid that the biggest key is this barren mountain, to be exact, the unknown under the mountain.

It's a pity that the sword master who hates the sword has no news now, and he doesn't know life and death.

Otherwise, I may be able to get some unknown secrets from his mouth.

"Click!"

Just when Su Daochen passed through this dead man's pit, a drastic change happened!

Not far away, in the unfathomable pit, the dense bones of the corpses trembled, making a clattering and piercing sound.

Immediately afterwards, those scattered and different broken bones were spliced together between the naked eye to form a "bone man".

In just a breath, thousands of skeleton figures appeared in front of Su Daochen's eyes, all of them were cold, with teeth and claws, stiff steps, and approached him a little strangely.
