The green robe suddenly burst into a burst of aura, and a layer of glow appeared, which immediately bounced off Yan Wubian's wisp of divine consciousness, and the nearby aura also fluctuated strangely.

"Hey, this robe is a bit weird!"

With a light sigh of surprise, Yan Wubian, who was a little surprised, quickly returned to his normal color on his face, and after muttering, he grabbed the void in front of him with one hand.

With a shake of the green robe, it suddenly turned into a piece of green light and flew directly out of the skeleton and flew into Yan Wubian's palm.

The green robe was extremely soft in his hand, exuding a warmth, it didn't seem to be anything peculiar, gently stroking the green robe in his hand, Yan Wubian's face couldn't help but flash a look of enlightenment.

"The material of this green robe should be woven from an ancient demonic beast skin, which can resist the detection of the cultivator's divine sense, and it seems that it also has the function of heat insulation, which can be regarded as a rare thing. ”

As soon as the words fell, Yan Wubian casually put away the green robe, and turned his gaze to stare at the bones that had been exposed, a small cyan storage bag, which was wrapped around the bones around his waist.

With a slightly happy face, Yan Wubian took a few steps forward, carefully picked up the storage bag, and swept it inside with his divine sense, his face couldn't help but be stunned.

The space inside this storage bag is extremely huge, nearly 100 times that of an ordinary storage bag, however, there are not many things in this large space.

Yan Wubian then flipped the palm of his hand, and the opening of the storage bag in his hand was facing downward, and after a flash of spiritual light, a large number of things were immediately revealed on the ground.

Most of the things in front of me are pieces of red crystals, all exuding a scorching and roasting atmosphere, which seems unusual. In addition to this, there was a jade box, a white medicine bottle, and a long red knife.

Looking at these things, Yan Wubian's eyes narrowed halfway, and he could already recognize the long knife at a glance as an ordinary spirit treasure, which had almost no attraction to him. On the contrary, it was the contents of the jade box and the medicine bottle, which aroused his great interest, because under the sweep of his divine sense just now, he could not forcibly invade it, and he didn't know what the jade box and medicine bottle were made of.

As for those reddish red crystals, they made him feel a little familiar, as if he had seen the introduction of such a thing somewhere.

"This thing seems to have been tried...... , spiritual material, this is the rumored spiritual material!"

Picking up a piece of crimson crystal, Yan Wubian frowned slightly, and after thinking about it for a while, he immediately remembered the introduction of this kind of thing mentioned in that ancient book, and couldn't help but exclaim in surprise.

Spiritual material is a special material used by ancient refiners to refine spiritual treasures, and its refining method is somewhat special, most of them will use some rare materials combined with a certain refining method to form spiritual materials.

And these crimson crystals at the moment, it is obvious that this cultivator who has fallen here wants to refine a powerful fire attribute spirit treasure, so he will carry so many spiritual materials with him, and it seems that the power of the spirit treasure refined with this spiritual material is definitely not trivial.

Yan Wubian was still wondering how there were so few things in the storage bag before, obviously, this skeleton should have used most of its resources on these spiritual materials before his death.

As for the long knife, although it was not of much use to him, it was also a rare spiritual treasure after all, and it was naturally impossible for him to let it go at will, and it was also included in the spirit pet space again.

Immediately after, Yan Wubian checked the white medicine bottle, however, the medicine bottle was empty and there was nothing, which couldn't help but make him feel a little disappointed.

After putting away the empty medicine bottle, Yan Wubian stretched out his hand, and the white jade box flew into his hand with a "whoosh". Then I slapped the jade box and opened the lid.

But just as the palm of his hand slapped on the lid of the box, a layer of glow emerged from the lid of the box, bounced Yan Wubian's palm out.

"There is a ban!"

Yan Wubian was stunned for a moment, and then without any hesitation, the spiritual light in his hand flashed and grabbed the lid of the box again.

The glow on the jade box reappeared, but under Yan's boundless power, the glow was obviously unable to withstand the huge force on the palm, and it had already collapsed in a few breaths.

Then, Yan Wubian grabbed the lid of the box and opened the lid of the box. As soon as his eyes froze, he immediately saw the contents of the box, which turned out to be a simple topaz Jane.

After hesitating for a moment, Yan Wubian still carefully took out the jade slip and put it close to his forehead, and his divine sense immediately broke out of his body, swept through the jade slip, and his face showed a look of surprise.

"Red Flame Knife?"

After carefully reading the contents of the jade slip, the corners of Yan Wubian's mouth moved and muttered to himself.

The content recorded in this piece of jade slip turned out to be a spiritual treasure refining method, and most of the materials used were spiritual materials and the like. Although the jade slip also has a method of sacrificial refining of spiritual materials, it actually requires the fusion and refining of forty-nine kinds of fire attribute spiritual materials, as well as many auxiliary materials. Most of these materials, Yan Wubian has basically never heard of, obviously these things should have long been extinct.

And those crimson crystals are the spiritual materials needed to refine this flame knife, not even one-third, as for the rest of the spiritual materials to be collected and refined, it is basically a fantasy, Yan Wubian believes that even if he spends his life and searches for it in the Demon Domain and Sky City, he will not be able to collect all the materials for refining the flame knife.

However, Yan Wubian could see that the power of this flame knife was absolutely extraordinary, although it was only a chicken rib now, and it could only be used for refining research, but if he went to the fairy realm in the future, he might not have the opportunity to refine it.

Sighing secretly, Yan Wubian re-put the jade slip into the jade box a little carelessly, and just as he was about to re-close the lid, his eyes inadvertently swept over a piece of animal skin at the bottom of the jade box, his face couldn't help but be slightly stunned, and his heart moved.

"It's ...... The topographic map seems to be the topographic map under this sea of fire!"

Pulling out the animal skin in the jade box, he spread it out, looking at the pattern painted on it, a hint of joy could not help but emerge from his face.

Yan Wubian didn't expect that there would be such an unexpected joy in this box, to be honest, he had really forgotten the route he had walked in order to pursue Zu Xiyi before, and he was originally worried that he would encounter danger in order to find an exit from this place, and running around, with this map, not only did he not have to worry about getting lost in it, but his own safety would also be greatly increased.

Without any delay, Yan Wubian immediately carefully studied the map in his hand, and after a while, he exhaled a long breath and muttered to himself in disbelief:

"It turned out to be a treasure map, there are still treasures hidden in this place, the ancient tomb marked on this map, could it be the secret place of the Blood Demon Holy Ancestor?"

As soon as the words fell, as if thinking of something, Yan Wubound's eyes couldn't help but flicker.
