A huge mountain peak has completely turned into a huge volcano with a hollow middle, and it doesn't seem to be very big from above, but when the three of them stepped closer, they realized that the height of this volcano was more than 10,000 feet.

Standing at the foot of the mountain and looking up, feeling it reaching into the sky, Bu Tianxiang took out his flying sword from the storage ring and immediately transformed into a giant fiery red flying sword.

Watching his actions, Yu Xinghai also took out his fiery red flying sword from his storage ring, and at the same time transformed into a giant flying sword, and then the whole person jumped on his flying sword, and after shaking it a few times, he was already standing firm.

Bu Shiren, who was originally standing beside him, stared at his actions with wide eyes, and he didn't even hear Bu Tianxiang asking him to fly the sword.

"Brother Yu, what kind of cultivation are you now, why haven't you even been able to make a flying sword for a few days?"

Bu Shiren's heart was full of shock, when he first met him, it should have been ten or twenty years ago, that was when he was still a first-level Qi refining monk who was beaten by someone who used a secret talisman to escape.

But now in just twenty days, the other party can already make the flying sword, he knows that the other party's background is extraordinary, from the fairy world, but he can re-cultivate after the loss, this speed is too fast!

Twenty days, from a rookie to a monk who can get on the table, what an astonishing speed.

"I am now refining qi at the eighth layer, because I have the spiritual power of the five attributes in my body, so the spiritual power content is much higher than that of ordinary monks, and now I have the spiritual power contained in ordinary monks on the first floor of the foundation, so I can barely fly with a sword. Yu Xinghai smiled at him.

Listening to what he said, Bu Tianxiang's heart was also floating, a trace of different color flashed between his eyebrows, and he stared at him and fell into a deep groan.

"This kid's cultivation can improve so quickly, it seems that there are a lot of secrets on his body, and I don't know if it is a blessing or a curse for the young patriarch to follow him to cultivate!"

Just as Bu Tianxiang was groaning, Bu Shiren sighed for a while, and then jumped on his flying sword, for him, in fact, this time he was already a little satisfied with breaking through two layers of cultivation in a row.

He can't be compared with Yu Xinghai, the demon, as the so-called people are more dead than people, and he can't be too greedy, otherwise insatiable greed will make people fall into an irreparable situation.

Edgeworth slowly crossed the peak and flew above the crater, but the massive volcano had not erupted, so they could withstand the scorching heat of Edgeworth's levitation directly above the crater.

The crater is huge beyond ordinary people's imagination, and the top of the eruption crater is 100 zhang wide, and the deeper you look into the crater, the wider it becomes.

If the overall appearance of this volcano is described as an inverted funnel-shaped, the entire volcano is almost hollowed out of the entire peak, the lowest layer is 20,000 zhang below the depths of the ground, and its breadth is at least a few thousand zhang.

Just imagine, locking a fist-sized purple Xuanhuo in the vast magma layer of thousands of zhang is like looking for a needle in a haystack, if it weren't for Yu Xinghai using the Heavenly Demon Eye Vision, it is estimated that he would not be able to find the purple Xuanhuo in the tumbling magma layer.

"Brother Yu, are we going on like this?" Looking at such a huge and terrifying volcano, Bu Shiren suddenly hesitated, to be honest, let him come to such a place by himself, even if he was given 10,000 spirit stones, he would not go.

What are you kidding, although he is greedy for money, he will not joke with his own life.

Looking at his appearance, Bu Tianxiang glared at him, and said with some reproach: "What's the matter, boy, are you afraid! This is where you insist on coming." ”

"Ahem" Bu Shiren coughed dryly twice, and replied with a somewhat embarrassed smile: "This volcano is indeed a little scary, but isn't there a little uncle here now, you won't die for a while, right?"

"Hmph, if I hadn't saved you from death, I wouldn't have come to this Flame Mountain Range to save you before, let you endure hardships, and let you run around all day long!"

"Hehe" Hearing this, Bu Shiren had no choice but to laugh dryly.

"Build a few more defensive shields for your body, let's go down now, you kid be careful for me"

After speaking, Bu Tianxiang looked at Yu Xinghai, who was also above the Sword's suspended crater, and glanced at him meaningfully.

"Nephew Yu Xian, let's go down! You should be careful yourself, such a place is extremely dangerous, and I can't take care of the two of them at the same time, so"

Bu Tianxiang didn't finish his words, just because Yu Xinghai had already nodded to him and said, "Uncle Xiang, don't worry, I will take care of myself, don't worry too much about you." ”

Yu Xinghai naturally has a sense of proportion in his heart, and he will not forcibly move the purple mysterious fire without being completely sure.

Immediately, the two of them controlled the flying sword and slowly fell towards the crater, and a scorching energy suddenly burned the shield of the flying sword's expansion into a sizzling sound.

"What's that?"

Just descended less than a hundred zhang away, but Bu Shiren suddenly stared at the crystals on the inner wall of the volcano that were crystal clear and flashing red, and shouted loudly.

As he spoke, he couldn't help but sniff into the air fiercely, and then his eyes lit up, and he shouted again with excitement, "Treasure!

After he reminded him like this, Bu Tianxiang and Yu Xinghai followed his gaze to the inner wall of the volcano at the same time, and then they showed shocked expressions at the same time.

The flaming red and crystal translucent things on the inner wall of the volcano in front of him turned out to be all fire spirit crystals.

The fire spirit crystal is a kind of spar that contains a large amount of fire attribute spiritual power, and its characteristics are similar to the spirit stone, but the spiritual power contained in the spirit stone is attributeless, and the monk with any kind of spiritual root can absorb and transform into the corresponding attribute spiritual power, while the fire spirit crystal in front of him contains the fire attribute spiritual power, which is only suitable for the monks of the fire attribute spiritual root to absorb and use.

Of course, this is limited to mortal dust, for the immortal world, the monk has the spiritual power attribute transformation technique, so a treasure that is more advanced than the lower grade spirit stone can be described as a sought-after thing.

With so many fire spirit crystals covering almost the entire inner wall of the volcano, since both of them had previously focused their eyes on the magma at the bottom of the volcano, if it hadn't been for Bu Shiren's reminder, they might not have noticed it so quickly.

"Haha, I sent it, I didn't expect my Bu Shiren to change his appearance, but the blessing is still the same as back then" Bu Shiren suddenly laughed, and then opened his mouth to Bu Tianxiang who was shocked, urging: "Uncle, quickly put the flying sword close to the inner wall of the volcano, let's quickly dig up some fire spirit crystals." ”

As soon as these words came out, Bu Tianxiang did not reply, but he commanded the flying sword, turning into a streamer, and the tip of the sword was directly inserted into the hard and abnormal inner wall of the volcano with the power of thunder.

These fire spirit crystals in front of him are also an incomparable cultivation treasure for him with a fire attribute spirit root, if he doesn't take the opportunity to dig up some, how can he afford to take the risk of coming to this volcano?

Yu Xinghai's movements were also not slow, and in a flash of sword light, the tip of his flying sword had already been slanted into the inner wall of the volcano on the other side, and the metallic long sword in his hand suddenly appeared in his hand, and after a flash of golden light, it shrank into a mini sword with a length of seven inches.

In a flash, he had already come to the inner wall of the volcano, and between his hands and hands, he had already used the tip of his seven-inch small sword to dig out a fiery red crystal from the inner wall.

This crystal is not large, found with two fingers, in a diamond-shaped state, under the light of the fire, shimmering translucent.

What is striking is that there is a fiery red flame that seems to be burning in the middle of the translucent crystal, which looks unusually beautiful.

On the other side, Bu Shiren and Bu Tianxiang were already digging up the fire spirit crystals in front of them quickly and even a little frantically, and the craziest of them was none other than Bu Shiren, who had always been very greedy for money, and I saw that he didn't know when he took out a low-level magic weapon that looked like a small hoe and an iron pickaxe from the storage ring that specialized in digging spirit stones.

From this point of view, the other party has done this kind of thing a lot, and that kind of tools and skillful digging techniques are not comparable to Yu Xinghai and Bu Tianxiang.

However, the more Yu Xinghai and the others dug, the more frightened they became, and they were shocked to find that after digging up another layer of fire spirit crystals, they were simply inexhaustible.

Digging and digging Yu Xinghai, he couldn't help but copy the Yuan Shen into the state of the Heavenly Demon, the stars flashed in his eyes, sweeping towards the inner wall of the entire giant volcano, followed by translucent fiery red crystals, and most of the volcano in front of him was actually formed by fire spirit crystals.

It was the first time Yu Xinghai had seen such a huge fire spirit crystal vein, and then he couldn't help but wonder, since this peak was all fire spirit crystal veins, why had it become a huge crater?

This is not at all reasonable, the veins of fire spirit crystals are generally not swallowed by earth fire or magma, because their energy and hardness are not devourable or destroyed by the former, and it is even more impossible to form such a huge crater.

Some of the things he couldn't figure out, so he simply stopped thinking about this problem, and for now, he still mined more Fire Spirit Crystals, what he needed now was such cultivation resources, and it could be said that no matter how much he said, he wouldn't be too much.

After discovering that the inner wall of the volcano was full of veins of fire spirit crystals, he no longer dug them one by one, but simply transformed the metallic flying sword into a giant flying sword, and shot it to the inner wall with the power of thunder, and then stirred on the inner wall, and as the smoke and dust filled, countless fire spirit crystals fell.

At the moment when these fire spirit crystals fell, Yu Xinghai waved his hand and ingested them into the immortal spirit storage ring, repeating the action repeatedly, and those fire spirit crystals quickly decreased.

Such a movement immediately alarmed Bu Tianxiang and Bu Shiren, who were digging fire spirit crystals one by one, and when they saw him using such a barbaric method to dig up fire spirit crystals, they couldn't help but burst into a foul mouth.

"Can I do this?"

Both of them said a word of nonsense, and then they did it as it was, and at the same time, a low-level flying sword came out of their respective storage rings, frantically mining an incredible number of fire spirit crystals.
