Xia Mu held a map found from Hao Qingqiankun's bag in his hand, followed by Li Cheng and others, and a group of people searched for treasure on the barren beach according to the signs on the map.

Of course, the premise is that the final destination marked on this map must have treasures, in fact, from the time they got this map to the present, Xia Mu and the others don't know what exists at the end of this map, maybe it's a treasure, maybe it's a dangerous place, or it's a gathering point for all the monks in the Song Kingdom who lurk in the treasure mine mountain range?

In short, everything didn't matter, because Xia Mu and the others had already walked nearly two-thirds of the way according to the instructions on this map, and they were not far from the destination marked on the map.

This is a desert that occupies a circle of several miles, about five hundred miles away from the center of the barren beach, which makes Xia Mu a little surprised, you must know that although the barren beach is barren, but other places are still full of rubble, but there is a small desert marked here in the map, and it is difficult not to feel strange in this situation on the barren beach full of rubble.

Xia Mu turned his head to look at the people behind him and asked, "Don't you think this place is a little strange when you are on your way?"

"Senior Brother Huixia, when we were on our inspection, we also focused on exploring this place, but in the end we didn't find anything, so we temporarily ignored the strangeness of this place. A disciple in the courtyard replied.

Xia Mu was speechless, but it couldn't be said that they didn't investigate carefully enough, it could only be said that everyone subconsciously didn't think that there was anything valuable on the barren beach, so even if they felt that this desert was very strange, but after they didn't find anything valuable, they subconsciously thought that the appearance of this place was just accidental.

In fact, if it weren't for the destination marked on the map was this desert, Xia Mu himself would probably find it difficult to imagine what would be buried under this desert.

Sighing softly, Xia Mu looked around at everyone, and said with a smile on his face: "Let's start digging and see what Song Guo has buried under this." ”

"Yes. Everyone agreed, and under the pinching of their hands, they joined hands to launch the sand control technique.

With a bang, the entire central part of the desert began to roll, and then the sand in the center of the desert began to move towards the edges, gradually revealing a deep pit, and the scope and depth of the pit continued to change as everyone continued to carry out sand control techniques.

About half an hour later, just when the spiritual power in everyone's bodies was about to be exhausted, a dilapidated stone gate appeared in everyone's sight. There were cracks and sand everywhere, but there were still traces of people who had been there, and occasionally some discarded spirit stones used by monks could be seen.

The stone door was opened, and a deep passage appeared in front of Xia Mu, Li Cheng and the others, Xia Mu noticed that the rock used in the passage was actually an extremely low temperature deep-sea ice rock, which seemed to have been transported to this place from an extremely distant place, or was this barren beach once an ocean?

Xia Mu's face showed a solemn look on his face, and said, "Follow me, cheer up." ”

"Senior Brother Xia, don't you need to report to the higher authorities first?" a disciple in the courtyard asked in a low voice.

Xia Mu walked down the stairs of the passage and said, "I don't know what is inside, how can I report to the top?" at least figure out what is below." ”

Hearing this, the disciple immediately smiled, indeed as Xia Mu said, at present, everyone has not found anything here, if they report it rashly, on the one hand, it is not good for the above to decide what level of monks to send according to the situation, and on the other hand, if there is nothing here, it will be suspected of false reporting.

The passage was much deeper than everyone imagined, and Xia Mu could feel that the temperature in the air began to rise gradually.

There were no words all the way, as everyone continued to advance, the exclamation in Xia Mu's heart became stronger and stronger, the length of this deep-sea ice rock passage has exceeded ten miles, and it is still extending downward, what an amazing amount of work is this?

In other words, what is hidden in the ground of this barren beach, which is worthy of such a vast project that the Song Kingdom has spent so much effort to build. Of course, this passage is not necessarily built by the Song State, but one thing is certain, that is, the secrets that exist here are by no means simple, otherwise the Song State would not have sent a team of monks to sneak into the barren beach at such a sensitive moment.

Gently exhaling a scorching breath, Xia Mu led everyone to continue to move along the passage, he could feel that he was constantly going deeper and deeper towards the center of the earth, and the temperature in the air along the way was getting higher and higher, and even Xia Mu felt a trace of heat.

After continuing to walk for another half an hour, the deep-sea ice rock passage in front of them finally came to an end, and the eyes suddenly opened up, but everyone was so shocked by the scene in front of them that they couldn't speak.

The crimson magma tumbled and bubbled slowly, and what appeared in front of everyone was a river of lava with no end in sight, and the air was filled with a strong smell of sulfur as the overwhelming heat wave hit.

Xia Mu's gaze suddenly fell on the other side of the magma river, which was red, covered with red stones, flashing with a mesmerizing golden-red light.

The pupils in Xia Mu's eyes shrank suddenly, and a look of disbelief appeared on his face.

"The best Yanyang Stone is the best Yanyang Stone. Before Xia Mu could speak, Li Cheng on the side could judge it by his appearance alone, and couldn't help but shout in surprise, and the rest of the people also had excited expressions on their faces.

The best Yanyang Stone is the top material for creating fire-attribute spirit treasures, and the size of an ordinary fist is worth millions of lower-grade spirit stones, and there is actually a whole vein of the best Yanyang Stone here, if this matter spreads, it is estimated that even the powerhouses of the immortal realm will be alarmed. And as the discoverers, if they report, according to the regulations of the hospital, they can own one percent of the best Yanyang stone of this vein, if it is converted into a low-grade spirit stone, it is conservatively estimated to be about tens of millions.

Of course, the big head must be Xia Muna, but even so, the rest of the people can at least distribute hundreds of thousands of spirit stones, which is simply a windfall.

"Senior Brother Xia, the veins of the best Yanyang Stone are not trivial, and we must immediately report to the courtyard, so that the courtyard can arrange for a master to come and sit down. Li Cheng on the side took a deep breath and forcibly suppressed the excitement in his heart.

Hearing this, Xia Mu nodded and said, "I'll use the messenger talisman to pass on the news now, Li Cheng, you take all your juniors and disciples to explore this place and see if there are any new discoveries besides this superb Yanyang Stone vein." ”

"Good. Li Cheng didn't talk nonsense, and shouted directly: "Senior brothers, spread out in pairs to see if there are any other treasures in this underground cave, if you can find them, the credit will definitely not be able to escape." ”

The crowd agreed.

So the twenty-two disciples in the courtyard dispersed in groups of two and began to explore around the lava river.

"It's really good luck that I actually found a top-grade Yanyang Stone vein, which is enough to rank in the top ten among the many veins that our Qiankun Holy Courtyard has. This time, we followed Senior Brother Xia to the right person, and when someone was sent down, each of us would definitely harvest more than hundreds of thousands of spirit stones. Some of the disciples were smiling and whispering as they patrolled along the lava river.

Xia Mu also had a smile on his face, but he was much calmer than the others, and he was not stunned by the huge cake that fell from the sky, but immediately took out the messenger talisman from the Qiankun bag, and transmitted everything here back to the courtyard through the messenger talisman.

After doing all this, Xia Mu finally calmed down and began to look at the magma river in front of him again. Even from afar, Xia Mu could feel that it was filled with an incomparably large amount of fire attribute energy.

Probably only in such a place can such a superb vein of Yanyang Stone be cultivated.

His eyes swept back and forth on the magma river a few times, Xia Mu didn't find anything strange, so he walked boldly and reassuringly to the river.

The magma river in front of him contains an incomparably abundant fire attribute energy, which is an excellent natural fire source, for Xia Mu, he only needs to arrange some spirit arrays to guide the fire attribute energy in the magma river, and it can be used to practice alchemy, and the effect is definitely much better than the fire spirit array.

This magma river is also a treasure trove.

Xia Mu had already begun to think about how to use the magma river in front of him.

It was at this moment that Li Cheng rushed out of a cave with an injured disciple on his back, his face full of panic.

"What happened?" Xia Mu frowned slightly, carefully examined the disciple's injuries, and found that he was only hit by a huge force that caused him to faint temporarily, and did not suffer any fatal injuries.

"Suddenly, a salamander came out of the cave and injured Senior Brother Li......" Li Cheng's face was pale, but his speech was quite clear.

"Lead the way. Xia Mu handed over the injured and fainted Senior Brother Li to the care of other disciples who rushed to the scene after hearing the news, and followed Li Cheng towards the place of the incident with great strides.

When the two of them passed through three or four large caves in the cave, they came to the place where Li Cheng said the incident occurred, which was a very huge stalactite cave.

In the middle of the cave, a salamander several feet long was looking at the two intruders, Xia Mu and Li Cheng, with its red pupils.

"Elite-level fierce beast?" Seeing this salamander, Xia Mu was startled, but after some careful induction, he found that although the aura of the salamander in front of him far exceeded that of ordinary sub-elite fierce beasts, it did not reach the elite level. Strictly speaking, this is a powerful sub-elite-level beast that is about to advance to the elite level.

As soon as his eyes turned, Xia Mu saw that there was an extremely large nine-pointed teleportation array behind this salamander, and his face suddenly changed slightly, and countless conjectures flashed in his heart.

"Li Cheng, you stand back. Xia Mu stretched out his hand to signal Li Cheng to withdraw from the stalactite cave, and then grabbed his right hand at the palm of his left hand, and a purple-gold halberd flashed out from the palm of Xia Mu's left palm.

And when Xia Mu summoned the immortal halberd out of his body, the salamander also raised its head suddenly, and the flesh wings on its neck suddenly opened, its eyes were like needles, cold and ruthless, and it instantly entered a combat state.
