Leaving Sandaochuan, Deng An went straight to the west. After walking for about a hundred miles, he found an abandoned demon beast cave, the depths of this cave was a natural yin land, because the surrounding yin qi was much lighter, this was a rare cultivation treasure in the vicinity.

After Deng An walked into the cave, he planted five small flags at the entrance of the cave. After a while, bursts of yin qi were like a trickle, and began to converge from all directions to the small flags, and when the yin qi at the entrance of the cave reached a certain level, the five small flags emitted a multicolored light that was grayish at the same time.

At this time, if you stand outside the cave and watch, you can only see a piece of mountain rock, and you can't find the existence of the cave entrance at all, so you can avoid being disturbed by demon beasts or passing by the underworld.

This set of protective array flags with illusion is obtained from the Grimace Yin Stone. On the same day, he found this Yin Rong Stone in the place where Wang Da and Grimace's souls disappeared, but unfortunately, the other items on the two ghosts were turned into dust in that explosion.

This result illustrates the sturdiness of the Yin Rong Stone, and it is no wonder that those high-level meditation practitioners like to use it as a medium for storing things. Of course, in addition to being sturdy, it also has the inherent advantage of being easy to carry and being able to store a large number of items.

Before he got the Yin Rong Stone, Deng An always thought that the third-order demon beast corpse bone had been dismantled by the grimace and placed in his soul body, after the rock spirit mouse blew itself up, he was still heartbroken about it, until he got this Yin Rong Stone, he found that the original corpse bone was completely preserved in it. The length and width of the space inside the Yin Rong Stone are about seven or eight zhang each, and it is more than enough to store a complete rock spirit mouse corpse that is only one zhang long.

As for Kunshan, Deng An did not take his life. One is that he is not the kind of cruel and bloodthirsty person who will do whatever it takes to achieve his goals, the second is that he will soon leave the Burial Immortal Mountain and will not worry about the leakage of the news that he has the Yin Rong Stone, and the third is that he believes that Kun will make the right choice and befriend a refiner, which is definitely more valuable than spreading the news of the Yin Rong Stone.

Five days later, Deng An withdrew from his cultivation state. At this time, the damage suffered by his soul body in the Sandaochuan Rock Spirit Mouse Cave had recovered, and his spiritual power had reached its peak.

Deng An's mind swept away the Yin Rong Stone in his soul body, and the scene inside appeared in his consciousness. In addition to the bones of the rock spirit rat, in this space seven or eight zhang wide, there are also some miscellaneous precious items, such as the bones of a second-order demon beast, dozens of attached jade talismans, several yin spirit stones, and a small piece of yin stone, but the only one that does not have snow spirit leaves.

For this matter, Deng An quickly found the reason. He once followed the usage of the Yin Rong Stone explained by Master Zijin, wrapped the snow spirit leaf with spiritual power and mental power, and tried to send it into the Yin Rong Stone, but he was unsuccessful, but the half-dark weapon could be easily sent in. Judging by this, it's not that the grimaces don't have snow spirit leaves, but that they can't be stored in the Yin Rong Stone.

Deng An did not feel sorry for this, the value of the Yin Rong Stone alone was no longer something that could be measured by Xue Lingye, let alone the demon bones and bones inside.

Deng An'an moved, and a one-foot-long demon beast corpse appeared in front of him in an instant, and at the same time, a fierce and brutal aura rushed towards him. Even if there are no remnants of soul in it, it is still extremely lethal.

Deng An's mind couldn't help but sway, and he almost couldn't hold it, and after he reacted, he was so frightened that he hurriedly retreated four or five feet, and then he felt better in his heart. The third-order demon beast was really powerful, and just some of the aura formed by the bones could force him back. However, when he remembered the strength displayed by the remnant soul of the rock spirit rat, he was immediately relieved.

Let Pang Hai, Grimace, Wang Da and other meditative cultivators, and the bones that they did not hesitate to fight for finally fell into the hands of Deng An, and while he was happy, he also felt the troubles of happiness. He had tried several things, but he couldn't remove any of the bones. Perhaps, as Pang Hai said, only with the strength of the middle stage of condensation can he successfully break through the anger.

Of course, Deng An was not discouraged. Now that the corpse bones are in its hands, there is no need to worry about being taken first by other cultivators, as long as he waits for revenge, he can concentrate on cultivating for a period of time, and when he reaches the middle stage of condensation, he can take it out and use it.

What's more, the fact that the third-order cannot be used does not mean that the second-order cannot be used. He collected the bones of the rock spirit rat and took out another demon beast bone. The bones of this demon beast are only about three feet long, and the reason why it is said to belong to the second order is because it can be judged from the texture of the bones. However, it is impossible to draw an accurate conclusion as to whether this corpse bone is in the middle or late stage, but it can be collected in the Yin Rong Stone by Grimace, and it must be above the middle stage of the second order.

As for the name of the demon beast, Deng An was confused, he could only tell that it was a flying demon beast, in the Burial Immortal Mountain, this kind of demon beast was relatively rare, and several common ones were excluded.

However, if you don't know the original name of the demon beast bones, it will have a certain impact on the refining weapon, but fortunately, this impact is not too big, because, at least, it can be classified as a flying demon beast, and when refining the weapon, you can consider some dark weapons that are known for their speed.

From the information provided by Kunshan, Deng An quickly found a set of spiritual weapons called "Zimu Bone Arrow". The attack speed of this set of bone arrows is amazing, and even if it is used face-to-face, the opponent cannot defend against it. It consists of two bone arrows, one large and one small, and if used separately, each bone arrow is only equivalent to a quasi-artifact, however, if the two bone arrows are used together, in some cases, it can even exert the power of a medium-grade artifact.

Relatively speaking, the greater the power of the artifact, the more difficult it is to refine.

The two bone arrows in this set of spirit weapons are only infinitely close to the spirit weapons, which is not too difficult for the refining technology that Deng An has mastered so far, and the demon beast bones he uses are likely to be above the middle stage, and the success rate of the refining weapon will also be greatly increased.

Deng An didn't hesitate and immediately decided to refine the Zimu Bone Arrow.

After some preparation, he flicked his fingers forward, and the surface of the demon beast corpse was immediately like a gray-white film, and after refining for six days and six nights, a white substance like nephrite replaced the demon beast corpse bones and was suspended in front of him.

According to the amount of bone arrows needed to refine the child and mother bones, Deng An had divided the bones of the second-order demon beast into three parts, but two of the bones had been in the previous refining process, because there were some deviations in the control of the fire, causing them to all turn into ashes.

Fortunately, the last one was successfully refined.

Looking at the refinement of this purified demon bone, Deng An slowly calmed his mood, his fingers clicked, and he drove the ghost fire to divide it into two parts, one large and one small, and then used the ghost fire to shape them separately, gradually, one long and one short, two bone arrows, revealing the rudimentary shape.

Because the Yin pattern has not yet been depicted, the two bone arrows are like art treasures made of crystal, and the surface reflects not much brilliance in the space, making them more crystal clear.

Deng An looked at them, and his expression gradually became confused. At this moment, in his eyes, their surfaces were no longer smooth, but covered with mysterious lines. I don't know how long it was, but at what point his fingers started to move......

After another three days, in the depths of the cave where Deng An was, there was a clear roar.

"Whoosh!whoosh!" suddenly sounded in the darkness, and two crystal lights, one large and one small, quickly swept through the air, and a suspended stone turned into countless pieces without warning.

"The speed of this bone arrow is really amazing, if you take advantage of the opponent's unpreparedness, use it to sneak attack, I believe it can become a killer weapon to influence the situation of the battle, but it is a little difficult to drive them, without a certain amount of time to practice, I am afraid it is difficult to really use it freely. Deng Anxin thought in his heart, and with a finger from afar, the two bone arrows instantly merged and returned to his hand.

The child and mother bone arrows were finally refined.

This is a slightly gray surface, engraved with countless lines of crystalline bone arrows, if you judge from its appearance, it is difficult to find that it is composed of two bone arrows, one long and one short.

Deng An is not in a hurry to practice using it, and these tasks can be done on the road. He casually took out the jade talismans that Grimace had saved. Before going to Ju Kingdom, if you can master one or two spells of the Condensation Period, it will also be of great help to seek advantages and avoid disadvantages.

After checking five or six attached jade talismans in a row, Deng An's expression suddenly became strange, because the content of these attached jade talismans was exactly the same as the one he had purchased at Qianqiao Peak, and they were all introductory knowledge about the phantom fire refiner.

Grimace deliberately bought these things, and it seemed that he had guessed Mu Sen's plan, so he deliberately bought some out of his own considerations in order to cause trouble for the other party.

Through the words of that mysterious voice in the Yin Wind Valley, Deng An had already determined that the consignment of those meditation predecessors with jade talismans in Nian Wen Zhai must be Mu Sen. In this way, he used the Yin Spirit Bead as a temptation to deceive the Yin Cultivator who was able to condense the Ghost Fire to the Yin Wind Valley.

The only thing that puzzled him was what kind of relationship Mu Sen had with the owner of the mysterious voice, and what kind of agreement had been reached between the two parties, so that he was willing to find a suitable meditation for him.

However, for the time being, these issues have little to do with Deng An. He checked the remaining jade talismans one by one, and then threw them aside one by one.

Since he reached the condensation stage and the soul core gave birth to telekinesis, Deng An no longer needed to destroy the attached jade talisman to obtain the information inside like during the Nayin period, he only needed to use his telekinesis to probe lightly, and the information contained in it would be transmitted to his consciousness. Since the stored thoughts were relatively weak, they were no longer left when his thoughts were probed.

When he picked up the last jade talisman, Deng An swept it with his mental power at will, almost subconsciously wanting to throw it away, however, his hand suddenly paused and left it. His face slowly showed some unexpected surprise.

This turned out to be a reproducible jade talisman. The high-level meditation cultivators have strong mental power, and the attached jade talismans made by them can be reused.

Unfortunately, due to the existence of the Attachment Jade Talisman for too long, there were only seven or eight spells left in it, but the first of them was the one that Deng An had been looking forward to for a long time.
