The three girls all nodded when they heard this, and then Li Mo said: "Later, the former sect master arrived here, accidentally found the jade box, and encountered the great elder of Yanhuangmen outside, so only one box was left. ”

"This is really a twist and turn, fortunately, Brother Mo is familiar with the symbol of the mysterious sect, so he opened the box to obtain the Ten Thousand Dao Dan Sutra. Otherwise, I don't know how many years the treasure in this box will be sealed. Su Yan sighed.

"By the way, Senior Brother Mo, did you say that after the Great Elder of the Yanhuang Sect snatched another treasure box, did he open it?" Liu Ningxuan asked suddenly.

"This is not known, the Yanhuang Sect must not be an ordinary sect, as the only emperor-level sect in the country, it is a existence with the powerhouses of the Nine Realms. However, the box is very inconspicuous, and the method of opening it is unique, and there is a chance that it will still be in the dust. Li Mo said.

"The next volume is the next volume, and the question now is that there have been two jade boxes here, does it mean that there are really relics of that mysterious sect here?" Qin Ke'er said.

"If there are ruins, it is most likely under this thousand steel rock formations. Li Mo said.

At this time, Zhu Duanmu rushed over and said, "Sect Master, the entire grotto has been searched, and there is no entrance, the thousand steel rock formations have occupied the entire ground, and no mechanism and facilities have been found. ”

"Look for it again. Li Mo waved his hand.

Zhu Duanmu bowed and retreated, so everyone continued to search in the grotto.

Groping inch by inch along the land, looking for possible organs.

Li Mo also picked up his well-informed eyes, looking for it step by step, and it took him three days to finally find something strange in a corner of the grotto.

The surface of the rock formation is an inconspicuous bulge, and under Lingtong's eyes, there is a thick chain within the bulge, which extends downwards, and is obviously the location of the mechanism.

But the problem is that the chain has already broken before it goes deep into the eight zhangs.

"It seems that this place has also been affected by the war, and the mechanism has been broken, so there is only one last way left. Li Mo frowned slightly and said.

"What method?" Su Yan couldn't help but wonder.

"Digging. Li Mo said.

"But how do you dig this, this thousand steel stratum is very hard. Liu Ningxuan shook her little head like a drum.

Li Mo smiled slightly and said: "It is true that it is difficult for ordinary high-grade or even top-grade excavation tools to destroy the Thousand Steel Formation, but don't forget that we still have a treasure in our hands, that is, the horn of the Zhu Tong Corpse Caracal!"

Everyone suddenly realized that the horn of the king-level brute beast was not covered, it could be sharp enough to break everything, and it only needed to take a little bit as the tip of the digging tool, and the cost was very small.

Of course, even a tiny amount of horns can be a priceless treasure on the market, but for those who have harvested a full four full horns, this consumption is insignificant.

So, Li Mo and Zhu Duanmu began to refine excavation tools. But half a day later, a bunch of digging tools were smelted.

Then, Zhu Yuan and others began to excavate the strata within the scope of the organ.

Although the mechanism is broken, there are obvious signs of cutting in the formation.

As Li Mo said, the sharpness of the excavation tools made of corpse caracal horns is quite terrifying, although it still takes a lot of effort to dig up the stratum when digging, but Zhu Yuan and the others are also Xuanshi in the late Xuanyuan period, so the progress of the excavation is very smooth.

It took three days to dig down the trap and finally found the other layers of ore.

Li Mo saw the hidden stone passage in the depths of the mine under Lingtong's eyes, and immediately ordered to change the direction and dig horizontally, and after digging to the stone road, a passage finally appeared in front of everyone.

Descending along the stone path, the stone path is spacious but endless, just walking along the stone path takes half a day, and when you reach the exit, you suddenly see a huge underground world.

As far as the eye can see, there are dense underground forests and various karst caves.

The crystals in the rock formations on all sides exude a dazzling luster, and the rocks here are all translucent and radiate various brilliances.

Even the plants that grow here are translucent, and the colors are intertwined to create a fantastical world.

"Look, the fish in this pool are also transparent. ”

Liu Ningxuan shouted loudly on the side.

Everyone rushed over to take a look, and saw that there was a large pool formed by the convergence of underground rivers, and the big blue fish were swimming in it, and they were not disturbed by the approach of everyone.

"Bang-"

Xiao Hei jumped down and swam comfortably.

"It's such a paradise, I didn't expect there to be such a place deep underground. Su Yan sighed softly.

Li Mo couldn't help but nod and said, "Even if the spiritual veins are destroyed, the qi of heaven and earth here is still thick, and it is enough to reach the treasure land of the first-line sect." And there are thousands of steel formations to protect, I'm afraid that no one has been here here for thousands of years. ”

"But this place is not like the relics of a sect, but more like a treasure place for a few people to cultivate. Su Yanhu said suspiciously.

"People spread out and looked to see if there were any artificial structures. Li Mo waved his hand.

So the people dispersed again, and the underground world was very vast, with caves connected here and there, and all kinds of dense woodlands and rivers were everywhere, which seemed to stretch for hundreds of miles, and for a while there was no useful news coming.

However, there is no danger here, and the only brute beasts are herbivorous creatures, and they are not aggressive at all.

It wasn't until the seventh day that the disciples discovered a cave on a cliff with faint traces of artificiality.

Li Mo took the three girls and the others to the cave immediately, and when he looked up, the place where the cave was located was very hidden, and it was not easy to find it.

The entrance to the cave is not large, only allowing one person to travel, but once you walk in, there is a cave inside, first of all, there is a wide stone hall, which can accommodate hundreds of people, and there are several forks in it.

However, there are no stone tables and stone benches made of ordinary people's habitation, and there are no traces of cultivation in the small room that can be used as a branch of the cultivation area.

The so-called artificial trace is a trace that the disciple found on the corner of the fork in the road when he was investigating.

The traces were also extremely shallow and obvious, and if it weren't for the disciple's sharp eyes, it would have been difficult to find.

"It's weird, it's a good habitat to take care of it a little, plant it, dig out a pool, and make some stone beds and stone benches, but why is there no trace of human habitation? Su Yan said.

"It's just other traces of life, but there must be a cultivation ground to live here. Could it be that there are more habitable caves besides here?" Qin Ke'er pondered.

Several people were discussing on the side, and Li Mo felt the trace and slowly walked towards the fork in the road.

At the end of the fork in the road is a small cave hall, with groundwater seeping out of the rock crevice on one side, dripping and dropping water droplets, and the other three sides are translucent stone walls that exude a fluorescent luster.

It was empty as far as the eye could see, and there was nothing worth noting.

But Li Mo still used his Lingtong eyes, swept over ten feet and ten feet, and then suddenly his pupils dilated suddenly.

In the center of this stone wall to the east, there is a zone that even the eyes of the mind cannot penetrate!

He immediately strode over, but saw that the translucent stone wall was intertwined, and the middle part was an irregular rock the size of a palm, which was attached to the entire stone wall.

Li Moyun stared at it with a clear eye, and the thickness of a few inches of this rock, the translucent texture could be seen at a glance.

However, this is just an illusion.

Li Mo could not see through the inner structure of the rock with his keen eye, and as he observed, he found that the luster of the rock was subtle and different from the surrounding rock formations.

This rock and the surrounding rock formations are not the same material, let alone the companion of these rock formations, which means that this rock was inlaid here by someone the day after tomorrow.

And as he looked closely, there seemed to be a ripple of water on the stone under this luster.

Organ!

No, it's more like a mystery!

His heart jumped sharply, and he immediately said, "Uncle Duanmu, come and see, what is the origin of this rock?"

Zhu Duanmu walked over, stared at it carefully, then frowned, and said in surprise: "It's strange, this stone is natural, it doesn't seem to be artificially cast, but it gives people the illusion of a mysterious weapon, but it is too natural to say that it is a mysterious weapon, it is completely like a natural generation, and it has not been carved out." ”

Su Yan's three daughters also came over, but with their current eyesight, they couldn't see the reason.

"Could it be a celestial artifact?" said Zhu Duanmu suddenly.

When a sentence fell, everyone was shocked.

Li Mo nodded slightly and said, "Sure enough, Uncle Duanmu, you have the same opinion as me, this is not a stone, but a heavenly weapon!"

Everyone couldn't help but shush, and their eyes were all focused on this stone.

This seemingly natural stone turned out to be a heavenly artifact!

As a powerhouse of the Eight Realms Spirit Aperture Realm, the Heavenly Weapon can only be used and forged, representing the highest craftsmanship and the most powerful combat power of the Xuanmen, each of which is a Xuanmen Treasure and is enshrined in the Treasure Pavilion of the highest level.

But I never thought that this stone embedded in the rock wall would be a celestial artifact.

Li Mo stretched out his hand and brushed it on the stone, and there was a subtle touch on his fingertips, but his brows were furrowed, and he said to himself:

"What does it mean to be inlaid here?"

Everyone also exchanged their heads and whispered, but they were all worried.

"Could it be that there was an accident here back then, and then the owner of the Heavenly Weapon escaped?" Zhu Yuan speculated carefully.

"It's impossible! This is a celestial artifact, and if you don't die, you can't take it away. Zhu Duanmu waved his hand categorically.
