The hedron embedded in the top of the cave emits a soft glow like fireflies, and when you arrive at Moro Cave, you will see one of these glowing hedrons after a few steps. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Without the spar lighting, it would be difficult for anyone other than Xu Yan's left eye to see the surrounding environment clearly.

Originally, he didn't care about this kind of spar that grew in the stone, but Xu Yan accidentally found that a spar on the top of his head had fallen off the stone wall and was about to fall down.

Out of curiosity, he flew to the top of the cave and grabbed the hedr.

With a gentle tug, the hedron is in hand.

After landing on the ground, Xu Yan played with the fluorescent spar in his hand, and looked at it, his eyes began to glow with a layer of doubt.

The small spar is nothing special, there are many materials that can emit light in the cultivation world, and this spar is not a refining material, it is basically useless, but the edges and corners of this spar are a little different.

Although it is not boxy, it is also angular, very much like it has been cut out by someone, and it is definitely not a natural formation.

With a hint of doubt, Xu Yan raised his head and looked into the distance.

As far as the eye can see, dozens of fluorescent crystals on the top of the cave are similar in size, and the edges and corners are also about the same.

Xu Yan began to recall the places he had passed along the way, and in his memory, the fluorescent crystals that appeared on the top of the cave seemed to be all about the same size, and the distance between them was surprisingly consistent, and a piece would appear every two or three zhang.

From the neatly arranged fluorescent crystals on the roof of the cave, Xu Yan thought of some long passages in the palace, and the dome of those passages would be lit with everlasting lights.

"Morro Cave is not a royal palace......"

Xu Yan, who shook his head and muttered to himself, suddenly raised his eyebrows sharply.

When he looked at the fluorescent crystal on the roof of the cave in the distance again, an astonishing guess slowly rose from Xu Yan's heart.

Could it be that the fluorescent crystals here were deliberately left behind?

Unless someone did it on purpose, why are the hedrons arranged so neatly?

It was difficult to spot this vision when standing in place, because although the hedron glowed, it could not shine too far, and only by stopping under the hedron could it be seen carefully, so it would be difficult for ordinary Void Pill elders to perceive the arrangement of the hedron position, unless they had extraordinary eyesight.

Coincidentally, Xu Yan's left eye was extremely strong, and even in complete darkness, he could see far away.

Is it the fluorescent crystal left by the two powerhouses who explored Moro Cave last time, or is it left behind by other mysterious powerhouses?

When Xu Yan was muttering secretly, the people of the Money Sect had already arrived one after another.

Seeing that Xu Yuze was approaching, Xu Yan naturally took out the fluorescent spar and asked casually, "Elder Xu, can this spar be refined?"

"Fluorescent stone, light like fireflies, can only illuminate, basically useless, mostly buried in the ground, and different shapes and sizes. ”

Glancing at the stone in Xu Yan's hand, Xu Yanze could be regarded as seizing the opportunity to show off, and said: "If it is a huge fluorescent stone, there is a chance to refine a special magic weapon, which is not very powerful, but it can exude dazzling brilliance, and even the realm of Xudan cannot be looked at directly, it must be a whole piece, at least the size of a zhang, such a large fluorescent stone, no one wants it for nothing." ”

As an elder of the refining tower, Xu Yanze's understanding of refining materials is far beyond ordinary people, and at this time, he shook his head in front of Xu Yan, with a posture of pointing at the juniors.

"I see, taught. ”

Xu Yan nodded, not asking more, and waiting for Xu Yanze, who was waiting to say a few more words, was not disappointed.

"Although the magic weapon refined by fluorescent stone is not very powerful, it has a surprisingly winning effect, think about it, you turn over your hand and sacrifice a magic weapon, others haven't seen what shape it is, your eyes are blind first, isn't this invincible, how about it, do you want the old man to help refine a few, it's not expensive, five thousand spirit stones a piece, four thousand can also be, Elder Xu don't go, three thousand spirit stones can also be discussed!"

Ignoring Xu Yanze, Xu Yan raised the fluorescent stone in his hand and said, "I'll go ahead, you are a hundred feet away from me, this stone shall prevail, if I stop, you must not move forward." ”

After that, Xu Yan should go first.

With fluorescent stone as a reference, a Void Pill elder like Xu Yuze, who has a deep cultivation, is enough to see it from a hundred zhang away, and Xu Yan also does this to ensure that the people of the Money Sect do not collide with the people of the Heavenly Ghost Sect.

Walking quickly, after Xu Yan broke away from the crowd, his expression began to become strange.

The shapes are different and the sizes are different, this is what Xu Lize himself said, and with Xu Lize's understanding of refining materials, it is impossible to make mistakes.

However, the fluorescent stones in the entire Moro Cave are all similar in shape and the same size!

Thinking of the three-day entrance closure period, Xu Yan was even more confused.

If there is no time limit, it is okay, in order to see the surroundings clearly, the good and evil factions may make a move to leave fluorescent stones for lighting, but the three-day time limit, unless they are full of food, who will come to Moro Cave to install lamps?

Could it be that Moro Cave is a dangerous place deliberately opened up by someone?

Although he had doubts in his heart, there was a legend that Moro Cave was an immortal cave, and even though Xu Yan had some doubts about the origin of this dangerous place, he didn't care too much in the end.

If it's really the Immortal Cave Mansion, it's reasonable to leave some fluorescent stone lighting, but there's no need to fill every passage.

Even if there is an immortal, it should be a boring and eccentric immortal who likes to walk around his cave......

With the thought of slandering the immortal family, Xu Yan walked quickly, walking through the sand sea and stone forest, stopping from time to time to observe the surroundings and identify the footprints and traces left by the people of the Heavenly Ghost Sect.

There should be no danger in following the evil sect, this is Xu Yan's guess, and sure enough, after more than two hours, Xu Yan has been safe and sound.

During the period, I also saw some traps buried deep in the sand, and many monsters of different shapes, and finally found the corpse of a fierce tiger beast, the flesh and blood have been divided, only a huge skeleton remains, and it is a demon spirit at a glance.

There are free thugs in front of him, Xu Yan is happy and relaxed, less than half a day's trip, he finally saw the evil people in the distance.

In the distance, there should be a fight, and a buzzing roar can be heard from afar, and the earth shakes from time to time under your feet, and it seems that the fight is very fierce.

Jumping on a boulder, Xu Yan stared at it, and with the sight of his left eye, he saw an amazing scene.

At the end of the stone forest, a huge exit appeared, but in front of the exit, two giants stood in the way.

The giants are not humans, nor are they monsters, but two sandmen condensed from the yellow sand, three feet high, each carrying a boulder in both hands, and the earth will tremble between the rise and fall of the boulder.

At the end of the stone forest area, two strange sand man giants came out and completely sealed the exit.

"Spell or Forbidden?"

Seeing the sand man in the distance, Xu Yan frowned and muttered to himself.

This level of monster is enough to be worthy of the Void Pill powerhouse, and it can't be killed, people are made of sand, but those two boulders are thousands of catties, and the Void Pill can also be smashed into meat slurry when it is slapped on the body. (To be continued.) )
