Inside the cave, Yang Yan found a skeleton that was different from the other skeletons.

It was not a complete bone, but only a small leg bone, but Yang Yan found that even though he didn't know how long it had been, the other bones had been dried, but this one leg bone was still tough, and he didn't hurt it even a single bit with a punch with fifty percent of his strength.

This made the many doubts in Yang Yan's heart seem to have a thread to string them together, giving birth to a trace of enlightenment.

What kind of secret realm is the place of trials? Why is there a cave, and what are the daily necessities, and who is that leg bone, and what does it have to do with this cave?

Waiting for these, Yang Yan had a faint answer in his heart, but whether it was right or not would not be determined until he continued to explore this space more deeply.

After walking out of the cave, Yang Yan didn't stop long, left directly, and continued to walk in the previous direction, this cave and many bones seemed to have verified that the direction he chose was correct.

Along the way, he saw many bones, many of them were gathered together, and it seemed that they had died because of the competition for a certain treasure like the previous bones, in addition, Yang Yan also saw several caves, all of which were piled up with large pieces of corpses, and the caves were also looted, leaving nothing except ordinary daily necessities.

Some caves have even been artificially destroyed, leaving only some ruins, and even ordinary items have been damaged.

Yang Yan glanced at these caves, without pausing at all, because he didn't need to look at it to know what was going on there, and it was impossible to leave anything useful.

At this time, there must be many people who have found the right direction and are heading towards the real core of the trial land, the first to arrive will naturally have more advantages, and they can also get some treasures and the like first, racing against time, Yang Yan will naturally not waste time in these places.

"Huh?" At this moment, Yang Yan's eyes condensed slightly, and there was a sword intent in front of him that rushed into the sky, piercing the sky, even if it was so far away, Yang Yan felt that the sword intent seemed to rush into his body, extremely powerful.

"Go check it out. Yang Yan made a decision in an instant and rushed towards it.

When he came closer, Yang Yan realized that the place where the sword intent was located was also a cave mansion, but compared to the cave mansion he saw before, it was undoubtedly several grades higher, both the scale and the decoration of the cave mansion were extremely atmospheric, even if it had passed for an unknown number of years, it still could not be concealed, especially the sword intent, no one could ignore it.

The only flaw is that this cave was split in half by someone's sword, and the crack extended to the ground, which did not affect the beauty of the cave, and even because this sword was full of mystery, people wanted to find out.

And there are indeed not many people who have been attracted by it in the past and today, even more than other caves, and the corpses lying outside the caves alone are several times more than those in other places, which makes people palpitate.

Ignoring those corpses, Yang Yan looked at the gap in the sword, and felt that his eyes were stinging, it was a sword issued by a strong man who didn't know what realm, even the entire cave was split, and there was still a wisp of sword intent belonging to the strong man on it, although it had passed for an unknown amount of time, it was still very sharp, and at a glance, it was a great burden on the eyes, and I didn't dare to look at it.

Yang Yan could feel that this wisp of sword intent was not the same as the sword intent that rose to the sky in the cave mansion, that is to say, these were two kinds of sword intent from different people, and even from what Yang Yan personally felt, that wisp of sword intent was more profound and more powerful.

If his cultivation was stronger, he would definitely be more interested in this sword crack, and he would definitely have a good sense of it, but now it was extremely difficult for him to even take a look at that sword crack, and the profound meaning in it was not something he could comprehend at this stage.

Yang Yan glanced away from the crack of the sword and looked at the cave itself, compared to which this sword intent was much more accessible.

But it's just a little easier than that wisp of sword intent, and for Yang Yan, it's still unattainable, but he still has to give it a try.

In any case, with such a good opportunity in front of him, he couldn't give it up easily.

The cave is very large, it is necessary to call it a palace, there are atmospheric halls, gardens, and even mountains and jungles, if you see such a cave in other places, people will only feel the splendid atmosphere, the scenery is beautiful, but here, there is only a dead land, and there is no life at all.

Yang Yan walked through the cave mansion, and followed the sword intent to a large hall, the sword intent was emitted from here, and even as he got closer and closer, he could feel a fierce sword aura, very strong.

Yang Yan carefully avoided the sword qi that occasionally overflowed, and when he walked into it, he suddenly had a wonderful feeling in his heart, as if this sword intent was born for him.

There is this stone wall at the front of the main hall, and the sword intent is diffused from it, more precisely, it still comes from the pattern on the stone wall.

This pattern gives Yang Yan a sense of déjà vu, as if he had seen this pattern before. π

Yang Yan looked at the pattern on the stone wall, from the very beginning, it became more and more complicated, and the sword intent on it became stronger and stronger, more and more exquisite, and at the back, it was already a texture pattern composed of many complex lines, which was obscure.

"This pattern ......" Yang Yan's eyes flickered, he had indeed never seen this pattern, but he had seen something very similar to it, and he had copied it in his mind, and he would comprehend it when he had time.

At the beginning of the third layer of the Taihua Ancestral Tower, wasn't the test he encountered very similar to now, but at that time, he was not only facing sword energy, but also murderous energy, the two were fused, and the source was also a pattern on a stone wall, but it was not a texture pattern that I couldn't understand like this, but seven ancient characters.

Seven "killing" words, but contain different artistic conceptions, Yang Yan is still in the first "killing" word shallow comprehension, I can't imagine seeing a similar scene here.

Although the patterns are different, Yang Yan naturally links them together, and the patterns on it are not all containing sharp sword intent, and the simple strokes at the beginning give him the feeling of being like a sword, which is similar to the seven "kill" characters copied by Yang Yan.

It is impossible to distinguish between the two and which is higher and which is lower, but there is no doubt that if he can understand the patterns on the stone wall, it will also be of great help to him to comprehend the seven "killing" characters, and even improve his strength to another level.

This is simply an opportunity tailored for Yang Yan, if Yang Yan doesn't grasp it well, then he is not Yang Yan.

Yang Yan approached the stone wall, but he didn't dare to get too close, those sword qi were not easy to match, he didn't want to be injured in the first place.

His gaze is on the simplest pattern, and he feels it with his heart, this pattern has only one stroke, like a sword, and when he gazes at it with his heart, the sword is as if it is alive, ever-changing, and difficult to fathom.

Sure enough, even the simplest patterns aren't so easy to grasp, let alone anything else.

However, in terms of patience, Yang Yan has never been worried, he has not considered how many mysterious realms and opportunities are waiting for people to explore, if he can't even grasp the opportunities in front of him, let alone those unknown opportunities, the way to choose, Yang Yan has read so many books and classics, how can he not understand.

Yang Yan threw away all the chaotic thoughts in his mind, concentrated on the patterns on the stone wall in front of him, and gradually immersed himself in it, experiencing the artistic conception of the strokes, comparing them with the swords he had learned one by one, and even simulating the exercises over and over again in his mind.

Time passed little by little, Yang Yan stopped here, and other trialists were also looking for their own opportunities, many people knew where the core area was, and abandoned the peripheral opportunities, and rushed towards the core area frantically.

During this time, many people were attracted by the sky-high sword intent of the cave, such a sharp sword intent is so eye-catching, even if it is far away, you can feel it, but some people are not interested, because they don't cultivate the sword, and they can't understand anything when they go to enlightenment.

There were also sword cultivators who came later, but almost all of them hurriedly came to their senses, and left when they saw that there was nothing to gain, and some people didn't even set foot in the cave.

They have also seen some caves in the past two days, although they have all been looted, but it also let them know a little, the closer to the center of the cave mansion is more advanced, the stronger the people who once lived there, although the cave mansion in front of them is already very advanced, this Ling Tian's sword intent is also very attractive, but it is obviously not a central area, if it is easy to comprehend, it is fine, it is difficult, then it is okay, there are better and greater opportunities ahead, they naturally don't want to waste time here.

Therefore, although people have arrived here one after another, few people have ever set foot in the cave.

A few hours later......

"What a strong sword intent. A young man with a sword on his back appeared outside the cave, glanced at the crack of the sword and rubbed his eyes away, his eyes flickered slightly: "Such a strong sword breath, there must be a heavy treasure related to the sword, which is in line with my cultivation attributes, although I don't know what treasures against the sky will be in front of me, but there are more and stronger people snatching such heavy treasures, but it seems that no one has come to the cave in front of me, and maybe I can directly take the treasures into my pocket." ”

Thinking like this, the young man with the sword on his back walked towards the inside of the cave, and the soles of his feet stepped directly over the corpses on the ground, instantly rolling them into powder.

"Hmm, someone?" The young man with the sword on his back followed the sword intent, and quickly found the source of the sword intent, which was a stone wall, but to his slight surprise, a figure was looking at the stone wall in front of him.

It was a young man in a fancy costume, and he seemed to be looking at the patterns on the stone wall that he couldn't understand, and he didn't seem to notice the uninvited guest of the young man with the sword on his back.

The eyes of the young man with the sword on his back turned slightly, several thoughts flashed in his heart, and his steps were actually towards the stone wall, and he stopped not far from the young man.

"This brother, can you let you understand the pattern on this stone wall together? Rest assured, we each comprehend our own and don't scratch each other. ”
