The blood jade was very small in size, and it was covered by a pile of spiritual qi stones at the bottom, covering up a lot of the blood light, only revealing an insignificant trace, plus Yang Yan preconceived that he couldn't see anything good, so he didn't start to discover this blood jade for the first time.

That rich blood qi and evil qi, although I don't know what this blood jade is, is obviously not a mortal thing.

It is estimated that the young man with the sword on his back got this blood jade by chance, but he didn't know what it was for, and the evil qi on it seemed to erode people's minds, so he left it in the Sumeru ring and didn't care, but he obviously knew that the blood jade was not low, so he put it in the Sumeru ring, as for why he didn't sell it in exchange for cultivation resources, it is unknown.

Maybe it's reluctant, maybe it's because the wealth is not exposed, or maybe it's because the buyer's price can't satisfy him, these have nothing to do with Yang Yan, and he doesn't bother to bother to explore such a boring thing, he is more concerned about the blood jade itself.

As soon as Yang Yan's mind moved, the piece of blood jade appeared in his hand, and suddenly the blood qi that was dozens of times thicker came to his nose, which was disgusting.

This piece of blood jade is round and smooth, but the shape is not very regular, and it is quite comfortable to touch in the hand, but Yang Yan only glanced at it a few times and took it back, but instead of taking back the original Sumeru ring, he received his own Sumeru ring.

The blood light disappeared, Yang Yan breathed a sigh of relief, that blood qi was too strong, and that evil qi was eroding his mind all the time, even Yang Yan didn't dare to hold it in his hand all the time.

Although he only glanced at it a few times, Yang Yan didn't see its origin, but he remembered a name that was somewhat related to it, he had a strange stone called "Blood Evil Stone" in a book that recorded rare treasures, and the description on it had some similarities with this piece of blood jade.

It is said that the "Blood Stone" is a strange stone that is dripped from the hearts of countless martial arts powerhouses, and after countless years of precipitation, it forms a strange stone containing incomparably pure blood, and the unwillingness and resentment of the owner of these essence and blood at the moment of death will gradually integrate into an inseparable part of it in the formation of the strange stone, becoming an evil spirit, which can encroach on people's minds, so this strange stone is called, Blood Evil Stone.

It is rumored that this kind of blood demon stone gathers the essence blood and resentment of countless strong people, and it is an extremely precious tonic for martial artists who cultivate the way of killing, which can greatly improve their cultivation and enhance their perception of the way of killing, and even if the luck is against the sky, it is possible to obtain the artistic conception law of the strong person's perception contained in it, of course, not all blood stone can exist in the law of the strong, only the extremely rare and extremely high-quality blood stone has a certain possibility.

Regardless of whether these records are true or not, the Blood Demon Stone is an extremely precious and rare treasure, and although the blood jade obtained by Yang Yan is very similar, he does not think that it is the Blood Demon Stone, otherwise it is impossible for him to withstand the blood and evil qi in it with his current cultivation, it is a strange stone that has been poured by countless martial arts powerhouses with essence blood and resentment and has gone through a long time, and ordinary people are afraid that it will be eroded if they get close, let alone hold it in their hands.

However, even if this blood jade is not a blood stone, the similarities between the two are certain, and perhaps it also contains a lot of people's blood and grievances.

Yang Yan had refined some murderous qi in the Taihua Ancestral Tower, and the seven "killing" words obviously belonged to the scope of the killing path, if Yang Yan continued to go deeper on this road, he might be able to use this piece of blood jade.

Now that he can't absorb it, it's better to leave it for now.

Yang Yan transferred all the things in the Sumeru ring of the young man with the sword to his own Sumeru ring, and specially set aside a small space to store it, although he didn't like these, but there were always people who could see it.

Looking at the Sumeru Ring that had become empty, Yang Yan thought about it, but still didn't throw it away, and then Yang Yan turned around and walked in the direction of the temple.

I didn't expect that there would be unexpected gains from such a coming-and-going, but now the most important thing is the place of trial, and there are still many patterns on the stone wall that he has not yet understood, although he has been interrupted, Yang Yan can still continue to comprehend, and the impact is not very great.

There are a total of eighty-one patterns on the stone wall, from shallow to deep, from simple to complex, and constantly evolve into the last pattern, which is already a very powerful set of kendo skills of Paul.

Yang Yan stood in front of the eighteenth pattern, gradually sinking into enlightenment, as if there was a figure dancing the sword in his mind, the sword intent was soaring to the sky, and the roaring sword qi pierced the sky, and faintly there was a trace of the sky-rushing sword intent on the stone wall.

Time passed, Yang Yan stood motionless in front of the stone wall, his body straightened, a sword intent slowly emerged from him, the condensation of the sword qi was sharp, Yang Yan's whole person's breath seemed to change, becoming more aggressive, just standing there, it gave people a strong oppressive force.

It seems that Yang Yan itself is a sharp sword out of the sheath, ready to attack.

When Yang Yan quietly comprehended the sword intent in the pattern, outside the cave, there were people passing by one after another, and there were also sword cultivators among them, all of whom were attracted by the sword intent and were shocked by the meaning of Ling Tian.

Finally, one person couldn't resist the temptation, and walked towards the cave, and then a few more sword cultivators came, seeing that the clothes on their bodies seemed to come from the same force, and their temperament was extraordinary, and when they saw that person walking into the cave, their eyes flickered slightly.

"The sword intent here is particularly strong, there are bones everywhere, there must be heavy treasures, let's go in. As he spoke, his figure flashed like a sword, and the people behind him followed.

However, as soon as they stepped into the cave, they saw a figure quickly shuttling past them, and soon left the cave, and several people were slightly stunned.

"It's the guy just now. The leader stared, he watched the man go in, and now he suddenly came out again, could it be that the treasures of the cave have been obtained by him?

No, it can't be so fast, and the sword intent of the cave mansion has not weakened, which means that Chongbao is still there, and he should have seen something before leaving.

"Let's go. The leader snorted softly, his body was faster, he wanted to know what the man had seen, he didn't even want the treasure, and left directly.

"Senior Brother Nan......" The person next to him suddenly looked stunned, his steps paused, and he pointed to a corpse not far in front of him, feeling that his throat was a little dry.

"Huh?" The person who was called Senior Brother Nan was the leader of the three, and he looked in the direction pointed by Senior Brother, raised his eyebrows, and his figure flashed in front of the corpse.

"Qi refining realm fourfold. His eyes looked at the shocking sword marks all over the blood-red corpse, and there was still an amazing sword qi left on it, and he was slightly surprised in his heart: "What a powerful sword qi, seeing that he was clearly cut to death by the sword qi like this, he can use the sword qi to kill a person who refines the qi fourfold, and this person's kendo attainment is probably not much worse than his own." ”

"The body still has a remnant of temperature, apparently killed not long ago, and it looks like someone has arrived before us, and is probably still inside. Senior Brother Nan said, even if he understood why the person came in and left before, he must have seen this corpse, even the people of the fourth level of the Qi Refining Realm died tragically here, where would people below this realm dare to stay longer.

"Then do we still want to go in?" one person asked cautiously, his breathing was a little unstable, he was the weakest cultivator among the three, and he had only entered the third level of Qi Refining Realm a few days ago, if he encountered a strong opponent, he would be unlucky.

"Of course, there is only a corpse here that has died not long ago, and the person who killed him must still be here, which means that the treasure has not been taken, so let's go in. Senior Brother Nan's eyes were firm, and he took the lead in breaking into the depths of the cave.

"But......" The man was about to say something, but the other person directly interrupted him and said, "A corpse scares you?" With Senior Brother Nan here, even a person who refines the fifth level of qi can't make much of a storm, what are you afraid of?"

"That's right. When the man heard this, his heart instantly settled down, and he said no more, and followed the two men in front of him.

Following the sword intent, the three of them quickly came to the main hall where Yang Yan was, and found that Yang Yan was staring at a stone wall there, and the stone wall was filled with strong sword intent, and they couldn't help but be slightly stunned.

"Could it be that this stone wall is a treasure in the cave mansion?" Senior Brother Nan's mouth twitched slightly, as if he was a little disappointed, but this disappointment was quickly replaced by excitement, because he found that there were many patterns carved on the stone wall, each pattern exuded a terrifying kendo aura, obscure and mysterious, and seemed to be a powerful kendo technique.

The people in front of the stone wall also seemed to be comprehending these patterns, and if they could comprehend this set of sword techniques, their strength would definitely be able to improve to a higher level.

Thinking like this, Senior Brother Nan couldn't help but walk towards the hall, his eyes shining brightly.

"Get out. However, as soon as he stepped into the hall with one foot, the young man in front of him who was comprehending the pattern seemed to be aware of it, and spit out a word lightly.

The voice was extremely flat, but extremely harsh, Senior Brother Nan frowned, such an arrogant young man, let him go without looking back.

A cold light flashed in his eyes, of course he wouldn't listen to Yang Yan's words, at least he didn't think that the other party had this qualification, on the contrary, he wanted Yang Yan to roll, because he thought he had this qualification.

He stepped in with his other foot, and not only that, but he continued to walk inside.

"Let you go, didn't you hear?" Yang Yan's voice cooled down, and the sword intent on his body was even worse, cold and fierce.

"It's so arrogant, this hall is not yours, you can enter as much as I want, what can you do with me?" Senior Brother Nan sneered, disdainful at all.

"If you don't roll, you'll die. Yang Yan's face was calm, but his words suddenly became cold, the edge flashed in his eyes, the sword intent roared all over his body, and the terrifying sword qi roared out, tearing everything apart.

A powerful sword power pressed down, and even the air seemed to become sharp, Senior Brother Nan only felt that a peerless sharp sword was pointed at him, as if he was about to penetrate him from such a distance, as for his two junior brothers, they were all in their hearts, and they unconsciously retreated a little.

"It turns out that the person who died outside was killed by you. Senior Brother Nan raised his eyebrows, and instantly understood how similar this sword intent was to the sword intent remaining on the corpse, it was from the same person at all.

It's just that I didn't expect that it would be such a teenager with such a powerful sword intent, no wonder he was so arrogant.
