When he arrived at the entrance of the cave, Song Xiaotian did not rush in, but observed.

Standing in front of the entrance of the cave, he carefully observed everywhere, not letting go of any clues, knowing that whether it was a wild beast or a human, as long as he entered and exited the cave, he would leave traces. But he searched for a while, but found nothing, especially not a trace.

Just as he was about to give up, something unusual suddenly caught his attention, it was a depression in the ground, which he would not have noticed at all if he did not look closely, because at first glance it was also a dirt pit, and there was nothing special about it.

But if you look closely, you will find something peculiar, and you will even be stunned, because under the sweep of this depression, there are dozens of places, and this is not a pit at all, but some very large footprints, but such a large footprint, it is clear that they are not human, and the footprints are a foot and a half when viewed straight, and a foot horizontally.

"Oh my God, what kind of desolate beast left this behind. Looking at the huge footprints, Song Xiaotian was a little stunned in his heart, the footprints were so big, God knows how huge the body must be.

Looking at this huge footprint, he began to analyze it, and after careful observation, he found that the footprint spanned a large front and back, but the left and right spans were not very large.

With this situation, he couldn't help but wonder if this desolate beast was not a four-legged desolate beast, but a humanoid desolate beast? With this conclusion, he did not dare to be careless at all, and cautiously leaned into the cave, still praying in his heart, not to make a big man, otherwise the situation would be in trouble.

While approaching cautiously and probing carefully, Song Xiaotian didn't find any movement near the entrance of the cave, so he got up and walked towards the cave, the light in the cave was very dim.

However, due to the cultivation of the Dragon Form Transformation Divine Fist and the Burning Sun Technique, Song Xiaotian's eyesight was quite good, and at the same time, a wisp of Fire Dao Yuan Qi was condensed in his left hand, and a small fireball was born.

With this small fireball, the situation in the cave suddenly came into view, but after seeing this scene, Song Xiaotian had no other feeling except shock.

I saw that there were white bones everywhere on the ground, there were wild beasts, and there were human beings, what kind of wild beast lived here, so terrifying.

You must know that this cave is very wide, 100 zhang high and more than 30 zhang wide, and the thickness of the white bones on the ground is at least 10 zhang.

Looking at this scene, Song Xiaotian couldn't help but wonder how many humans and how many desolate beasts would have to accumulate the accumulated bones, what was going on here. Was there a big war? But it's not like it, because there is no sign of a battle. But if it wasn't for war, what would it be?

With such a question, Song Xiaotian continued to move forward, and the white bones on the ground were getting bigger and bigger, and the number of white bones was increasing, and he walked into the land of a hundred zhang, with the brilliance of the fireball, he was stunned by the scene in front of him, and what came into his eyes was a hall, the hall was very wide, at least occupying a circle of dozens of zhang.

However, the most striking and conspicuous place in this hall is near the end of the stone wall of the hall, because there is a bone mountain that is ten zhang high and covers an area of five zhang.

Looking at this bone mountain, Song Xiaotian couldn't help but feel a little chilled, because the bone mountain was refined by people by supreme means, and they were all refined together, but he didn't know how many lives this bone mountain needed to accumulate, and this bone mountain already exuded a metallic luster.

Looking at this bone mountain, Song Xiaotian glanced at it and found that this bone mountain was a supreme magic weapon, and it was still continuing

In the process of refining. He couldn't determine what level of magic weapon this bone mountain was, but he could be sure of one thing, that is, this bone mountain was terrifying.

Airplanes!

At this moment, suddenly the bone mountain shook slightly, and the white bones on the ground suddenly flew to the bone mountain on their own in a strange way, and then a bone fire came out of the bone mountain, the temperature of the bone fire was extremely high, and the white bones were immediately rolled up, and then immediately turned into white bone, and the bone fluid then seeped into the bone mountain.

"Shhh

When Song Xiaotian saw this scene, he was really stunned in his heart, followed by a kind of fear, this bone mountain is too weird, as if it has a will, it can operate on its own.

Suddenly, his eyes widened as he saw some blood-red impurities flowing out of the molten liquid on the mountain of bones.

The blood could not be forged by the bone fire, and then the blood was discharged.

Looking at this infiltrating scene, Song Xiaotian was extremely shocked, he didn't expect these bones to be so terrifying, so powerful, because the bones of ordinary people will dry up after the erosion of time, but these white bones seem to have existed for a long time, but now after the bone fire forging, blood can also appear, which is too terrifying. What does this mean? This can only show that the white bones in the cave are the white bones of some extremely powerful people and wild beasts, and only the white bones of the strong can resist the power of the years and reduce the speed of erosion of the years because they are refined by the vitality of the vitality.

The high bone mountain, the bone mountain with bloodstains, this white bone needs to be added regularly, because at the speed of bone fire such calculation and absorption, these white bones here will not last long at all, so from this point of view, it can be proved that this is not empty, it is a master land, but now this master is not here.

It's just that Song Xiaotian is thinking about one thing now, that is, the master here has gone there, whether the other party is a human or a wild beast, which needs to be known urgently.

Where did the bones of so many humans and beasts come from? The bones of the beasts are easy to say, but the bones of this human are not easy to say. Because the number of humans in this mysterious valley is so small, it is very difficult to obtain a huge human bone, unless ...... Unless this mysterious valley is not only the entrance to Ping'an Town, there are other entrances, and these other entrances have a lot of traffic.

Thinking of this, Song Xiaotian became even more vigilant, because it indicated that in this mysterious valley, there were not only wild beasts, but also human beings. Although the desolate beasts are powerful, they are easy to deal with due to intelligence problems, but humans are different, they have terrible scheming cities, and all kinds of other killing techniques. Temporarily dispelling all the distractions in his heart, Song Xiaotian began to think about the current problem, the current problem in the cave. The first question he pondered was, was the giant beast in the cave really not there?

But how could a desolate beast make such a move, you must know the existence of refining the bone mountain magic weapon, which is definitely something that only high-IQ creatures can do, and ordinary desolate beasts do not have such conditions at all, because IQ has always been the biggest weakness of desolate beasts.

The one who laid out this big array here was definitely a world-strong man, and the high-level desolate beast was not in Song Xiaotian's consideration for the time being.
