With such a strange black iron ball, it is difficult for Xiao Yan to imagine that there is no other harm, for example, if there is a poison attached to this black iron ball, he will be frizzy to touch, and the poisoning will be small, but if the detoxification fails, he will die.

Here, he must be cautious, one of the things that Xiao Yan collected before was that there was vinyl attached to its surface, and the vinyl was black in general with the book, in this case, Xiao Yan didn't care much, who knew that after the palm touched, it was directly glued, and after a lot of trouble, he took the ancient book from the palm of his hand.

With the lesson of the last time, Xiao Yan naturally will no longer be careless, and he will grow wise, so Xiao Yan at this moment does not dare to touch it directly with his palm.

The sword struck lightly on these iron balls, and it made a pleasant sound, Xiao Yan was dizzy when he heard it, the sound transmission effect of this iron ball was first-class.

"If you take these iron balls to form a formation, even if you add the Nether Sonic Wave Skill that you have mastered, the power will definitely increase greatly compared to the sound wave you have. Since the sound transmission effect of this iron ball is so good, Xiao Yan can't help but think of this, after all, his proficiency in the Netherworld Sonic Wave Skill is close to perfection.

It seems that if you want to break through this Netherworld Sonic Wave Gong, it is also an opportunity to need external objects, perhaps......

Picking up these iron balls one by one with a sword, Xiao Yan's mind moved, and the black iron balls resting on the blade of the sword disappeared from front of him one after another, and were moved to a relatively empty place by Xiao Yan's mind.

Since awakening the Phantom Eye, Xiao Yan also has a general understanding of the space in the Ring of Light, in general, in this Ring of Light, there are a total of three thousand small spaces, just like the Three Thousand Great Avenues, it is very easy to remember, and in these three thousand small spaces, there are different storage effects.

And the place where Xiao Yan moved these iron balls just now is the three thousand small spaces, which are dedicated to storing iron metal items, don't look at the three thousand small spaces in this bright ring, but each small space is three times the size of the storage ring.

The space inside the general storage ring is only four or five square meters of space, and the space of this bright ring is far more than one qiē!

Even Xiao Yan's temperament, after learning about it, he smashed his tongue.

When Xiao Yan put the last black iron ball into the Ring of Light, he found a record of this kind of iron ball in the last place where the iron ball was placed, and there was a note there, and the note was full of these, four big characters.

Xuanyin Thunder!

When the four characters of Xuanyin and Thunder were displayed in front of Xiao Yan's eyes, even Xiao Yan, who was calm, couldn't help but be moved, in this world, so far, he had never heard of flammable and explosive things similar to bombs.

"It turned out to be Xuanyin Thunder just now, my God, fortunately Lao Tzu put it relatively hidden, otherwise, the crystal nucleus that I got recently would have suffered. "The space for storing metal, compared to the space used by Xiao Yan at present, is indeed the most hidden one, at least, it is much farther away from the small space where the crystal nucleus of the renamed bird is placed.

After Xiao Yan's observation before, the crystal nucleus of the duplicate bird is placed under the ice for too long, and the original attribute of the crystal nucleus will be lost.

It's just that now the space with the crystal nucleus of the renamed bird all exudes a scorching temperature, although it is not as hot as before, but it is not to be underestimated.

"In a few days, Lao Tzu will slowly refine you, even if you can't refine it, you have to absorb it slowly. "I don't know how strong the fire attribute energy stored in this renamed bird crystal nucleus is, if Xiao Yan cultivates like this, in a short period of time, he will definitely be able to make the fire attribute in his body compete with the water attribute.

And the most important thing is that once Xiao Yan completely refines the crystal nucleus of the duplicate name bird, then it will be of great benefit to raise a small duplicate name bird in the future, once Xiao Yan is completely refined, and the duplicate name bird after having spirituality will inevitably recognize itself as a relative, even if it has no spirituality, it will also guard Xiao Yan's side.

After all, from Xiao Yan's body, there is the breath of his mother, and this kind of blood connection cannot be erased at all.

If it weren't for this small duplicate name bird, Xiao Yan would not have said anything to devour the crystal nucleus of the fifth-order demonic beast, and if he didn't have an explosion, it would be worth the loss.

And in the past few days, under the feeding of Xiao Yan, the little Chongming Bird has gradually entered a meditative state, Xiao Yan only gave a small piece of flesh and blood to the Chongming Bird before, and I really didn't expect it to take nearly three days to digest it.

Of course, the renamed bird at this moment will not meditate, and as for being choked to death, it is still very possible.

After observing the surroundings casually, when Xiao Yan didn't find anything worth cherishing himself, he took a step and walked forward.

The previous note about the Xuanyin Thunder did not introduce the role of the Xuanyin Thunder, but it can be seen from the name on the note that this must be an item with great explosive power.

As for how to use it, it didn't mention anything.

"It's finally almost here!" Xiao Yan was extremely excited at the moment, looking at the suddenly bright cave, and his voice sounded.

"Damn! What's going on?" Xiao Yan was depressed at the moment, he walked to the brightest part of the cave, but the qiē in front of him made Xiao Yan want to cry without tears, this is too fucking a hole, this cave, it turned out to be a front and back together, two passes, no matter how you go, you will never be trapped inside, the entrance of the cave is the exit, the exit is also the entrance of the cave, by the way!

Xiao Yan really wanted to scold the old mother of the person who dug the hole, you don't build a cave, and you won't build a normal cave?

Sue sù you, brother is prepared, but he wants to find a baby, okay, since he hasn't even gotten together a baby, Lao Tzu might as well just blow you up!

Xiao Yan is called an anger, no matter who it is, it is estimated that he will be very angry from hell by such a clay man, even if it is a clay man, there are still three points of fire, not to mention, Xiao Yan is flesh and blood.

Saying that, Xiao Yan actually took out the Xuanyin Thunder in the Zài Bright Ring that he had stored before, and the Xuanyin Thunder was heavy, and it was not lighter than his own sword!

"It's quite heavy!" Xiao Yan didn't feel the heaviness of the Xuanyin Thunder before, but now that he holds it in his palm, the heavy feeling goes deep into the bone marrow.

"Look at Lao Tzu blowing you up! Grandma's!" Xiao Yan pushed suddenly, and the Xuanyin Thunder had already flown out of his palm, and Xiao Yan had the brute strength to resist a big tree, and this sudden throw even threw the Xuanyin Thunder five zhang away.

I only heard a loud bang, but nothing happened next, Xiao Yan's original action of covering his ears also stopped abruptly at this moment, and he underestimated in his heart, "Damn, what's going on, it can't be fake, right?"

Suspiciously, he looked in the direction where the Xuanyin Thunder had landed before, and then followed with a probe, Xiao Yan was still afraid that the Xuanyin Thunder would suddenly explode again!

For this kind of thing, Xiao Yan, who has had a lifetime of experience, is not uncommon.

Until Xiao Yan approached the area around Xuanyin Thunder, there was no explosion, Xiao Yan couldn't help but really wanted to scold again, but he still held back, no matter how he said it, he was a very civilized person, how could he swear casually?

"Could it be that even this is fake?" Xiao Yan stood in a gray suspicion that this Xuanyin Thunder was also fake at this moment, didn't this thing explode after throwing it away? But he didn't find any switches that could be pulled on it.

Picking up the Xuanyin Thunder from the ground again, Xiao Yan looked very carefully this time, but he was even more disappointed.

"Damn, inferior products, fake and shoddy, I'll fucking ruin you!" Xiao Yan let out a furious roar, and the palm of his hand had been replaced by a bright light, which was the fighting spirit of the fire attribute.

The fighting spirit of the fire attribute was attached to the palm of his hand, Xiao Yan aimed at the Xuanyin Thunder in front of him and pushed it hard, and in an instant, the kick was also pushed five zhang away, Xiao Yan pushed it casually, and he really didn't expect his strength to be so great.

"Want to run, there is no door!" Xiao Yan looked at the Xuanyin Thunder that didn't want to stop, and a burst came out of his mouth, and then he saw a nameless fire in his palm, which condensed out, and then threw it towards the Xuanyin Thunder Whip five zhang away.

However, just when Xiao Yan's fire attribute fighting spirit hit the Xuanyin Thunder, an unimaginable scene arose, and Xiao Yan didn't know where to go at the moment.

With a loud "bang", Xiao Yan, who was hiding behind a huge and incomparable tree, was also shocked to the point that his eardrums were about to burst, and he was surprised, "Is this the case? In this way, the power of the Xuanyin Thunder can be fully released, but this is also a little too powerful!"

When Xiao Yan raised his eyes to look, the cave before that had been directly blasted out of a huge hole from the outside by the power of this Xuanyin Thunder, which looked very hideous, and at the same time did not lose that kind of grandeur.

However, Xiao Yan didn't have time to care about the qiē in front of him at the moment, but looked behind him worriedly, because behind him was his own academy, this loud noise, eighty percent of it had already resounded throughout the entire Canaan Academy, at that time, would he be punished?

Xiao Yan didn't dare to imagine it, and she didn't want to think about it.

But the more he didn't want to think about it, but he thought of it a little more, "No, something is wrong? The loud bang just now didn't seem to have spread for long, and it seemed to have stagnated!" Xiao Yan finally realized that something was not quite right, you know, there was such a loud noise just now, there was no possibility that there was no response, if so, it is very likely that the forbidden land has a sound insulation effect, and even, the forbidden place and the outside are directly two spaces.

"Damn, if I had known that I would use it like this, Lao Tzu wouldn't have been so wasteful!" The scene in front of him undoubtedly left the deepest impression on Xiao Yan, but Xiao Yan was also very glad that he had just pushed the Xuanyin Thunder away from a distance, otherwise, he would have become a ghost in hell at this moment, and he couldn't die anymore.

"Haha, in the future, if Lao Tzu is a demonic beast that I can't beat, or a human, I will take out the Xuanyin Thunder and let you see how powerful the master is. Xiao Yan faced the scene in front of him, smiled gloomily, and then turned around and walked towards a forest.

As he walked, Xiao Yan thought that this place should be far away from when he entered, and there was also a considerable distance from the entrance of the forbidden land, but it was strange, why was it not as hot as before?

"Could it be that my ability to resist the heat has improved? But this is not right, even if I have a high resistance to the heat, I can't feel the temperature outside!" Xiao Yan even felt that the heat here and what he felt before was simply two levels.

"Forget it, the changes in heaven and earth are the weirdest, Lao Tzu is too lazy to care!" Since he doesn't feel hot, at least it means that he can go ahead, and the purpose of his coming to the forbidden land is not to go to the inside of the forbidden land, and then see if there are any medicinal materials he needs?

"Blood Clotting Grass, Blood Crushing Grass, I'm cǎo fucking you! Where the hell are you? Don't let me keep looking for it. According to the records on the Longyuan fragment, the blood coagulation grass generally grows in areas with higher temperatures, and the more places where the temperature can burn people, the blood coagulation grass is the most, not only a lot, but also the quality of its medicinal materials is also very good.

There is also a record of the growth attribute of blood ginseng on the Longyuan fragment, blood ginseng, generally grows on steep cliffs, the temperature is the same as the growth characteristics of blood coagulation grass, it is in the kind of high temperature area, generally, the higher the temperature, the better the blood ginseng grows.

"But I don't know if there is anything in the forbidden land?" Xiao Yan blinked, fortunately, these two medicinal materials were all in a relatively hot area, if one was in a hot area and the other was in a cold area, this would be bothering Xiao Yan himself.

As he walked forward, Xiao Yan came to a waterhole, where the water was clear and he could even see the fish swimming in the bottom of the water, but there was no sound of flowing water in such a clear waterhole, and this was not the end of the water source, which could already be seen from the several branches that were separated.

"Good cold water. Xiao Yan complied, and patted the water in the water source lightly, which immediately stirred up a huge wave, but when the palm of his hand touched the stream in the pool, Xiao Yan's palm was quickly withdrawn, and the water here was very cold, and it could not be said to be water.

Xiao Yan had never seen such cold water, at least not before, and even the northernmost North Pole of the earth in his previous life, the ice and snow there may not be as cold as the stream here.

Xiao Yan took a step and walked into the edge step by step, he was also very curious about the water here, after all, he had been hot before, and he would not reject the water here at all.
