Wei Wuji saw that in the corner of the grotto, there was a phantom shadow, flashing by.

He hurriedly rushed over, looked around, and the first thought in his heart was that someone had come in!

But this idea was immediately overturned by him, and it was impossible to enter the grotto. This is an important place for the sect, and there are many disciples guarding it outside, and it is heavily guarded.

The second thought, this place has a strong aura, attracting demonic beasts to come.

But this is also impossible, the retreat is important, the sect has sent people to check again and again, and the birds and beasts in the Spirit Valley have been expelled, so as not to affect the cultivation of the disciples.

The third thought is that someone has set up a peeping circle in the grotto, and the phantom just now is a sign of the circle.

But after Wei Wuji carefully examined the grotto several times, he also overturned this possibility. With his current rune technique, it is impossible for the rune array of the five major sects to hide from his eyes. Maybe there is a magic circle, and Wei Wuji can't break it, but if he can't see it with his faceless eyes, there is absolutely no such possibility.

"It's really weird, I saw it, and I was definitely not dazzled. Wei Wuji was puzzled.

With his current strength, his divine sense and mind can be distinguished, and it would be ridiculous to say that it was inexplicably dazzling. But the phantom just appeared, and it was still under his nose, and the ghost disappeared, this ...... It's hard to explain, huh?

Wei Wuji thought about it, laid a rune array on the ground, and then ignored it and entered the gourd fairyland.

The grotto was uninhabited, so quiet that it could be heard when a needle fell, and after an hour, a phantom figure appeared, as if the light and shadow flashed through the crack in the door, and quickly disappeared into the distance.

For more than ten days in a row, Wei Wuji deliberately dodged, and the process from the appearance to the disappearance of the phantom was ingested by the rune array, and all of them were displayed in front of Wei Wuji's eyes.

"It seems to be a fluorescent light, not like a monster creature?, but the fluorescent knows how to hide, and it clearly has a hint of intelligence......"

Wei Wuji had never encountered such a thing, which made him puzzled, "Every time it disappears from this ground, is there something abnormal in this place?"

This grotto is a natural formation, and there are not many changes, except for the addition of stone tables and stone beds and some utensils, and the entrance to the cave has been slightly changed, and the magic circle has been shielded. Wei Wuji knocked on the ground, checked it carefully, and found that under the gap in the ground, it turned out to be a hollow.

Wei Wuji stretched out his hand and pressed it, and with a bang, the ground actually fell downward, revealing a hole the size of a sea bowl.

He looked down into his mind and found that the deeper the hole went, the more spacious it became, and after thirty zhang, it could accommodate the body to drill through. However, the depth of the cave has no end, and it goes straight down, and the divine consciousness and mind cannot reach the end.

"If you don't make a fool of yourself, you can clearly understand that this place can't cultivate with peace of mind. ”

Wei Wuji dug with both hands, and the solid stones fell like mud. After a while, Wei Wuji widened the hole and drilled his body into it.

After thirty zhang, Wei Wuji didn't need to dig, and his body could move forward. He continued his descent through the crevices in the rocks, and the passage grew wider and wider, and at first he had to crawl forward, then he could hunch over, and at last he was able to walk upright.

There was no fork in the road along the way, Wei Wuji kept going down along the passage, and it was estimated that he had walked more than fifty miles, and the road became a little smoother.

"I don't know where this cave leads?" Wei Wuji was curious and continued to move forward.

Walking more than ten miles further, Wei Wuji felt that the aura was getting richer and stronger, far exceeding the aura in the grotto. At this time, a fork in the cave appeared, and Wei Wuji stopped to observe and walked in the direction of the strong aura.

Along the way, Wei Wuji saw a lot of strange stones, the big ones were like hundreds of catties of boulders, and the small ones were like fists, and each stone exuded a rich aura.

Wei Wuji leaned over to inspect it, erasing the outer layer of the stone, revealing the essence inside, these stones were either essence stones, or essence stones, and some were spirit stones.

"Could it be that there is a spiritual vein in front of you, and the light and shadow are spiritual objects attracted by the spiritual veins......

Wei Wuji lowered his head and groaned, placed a few hidden runes on his body, and continued to walk forward.

There are more and more forks, and Wei Wuji's artistic conception discerns the direction of the flow of the aura, leaving a little mark, and always goes in the direction of the aura.

Along the way, Wei Wuji found no trace of the demonic beast, and just as he was feeling uneasy, a phantus suddenly flashed and drifted away into the distance.

"It's this phantom!" Wei Wuji's heart perked up, and he chased after the phantom.

The phantom was as fast as an illusion, and Wei Wuji's speed was not slow, and he followed closely behind, chasing all the way.

"There is no way ahead, it's a dead hole!" Wei Wuji's divine sense probed ahead, and found that there was no road ahead, and his speed suddenly accelerated a few points, approaching the phantom fluorescence.

Whew! The phantom flew straight towards the stone wall, penetrated the stone wall and disappeared.

Wei Wuji came to the stone wall, groped up and down to inspect, smashed it with a fist, and bang! The stone wall burst open, revealing a hole.

Without the slightest hesitation, Wei Wuji got in, walked more than ten zhang, and came to a wide cave. In the center of the cave, a huge round stone more than three feet high emitted a brilliant light. Several phantom fluorescents are slowly rotating in the air around the stone, as if they are arched guards.

"What kind of stone is this!?"

Wei Wuji hid in the dark, feeling the rich aura emitted by the stone, his expression was shocked, and his eyes were about to fall out.

The aura emitted by the stone, rich as mist, viscous as water, without a trace of impurities, lingers around the stone, like a silk ribbon.

Wei Wuji had never seen such a rich aura, even in the classics, there was no such record. He had no idea that the aura could be condensed to such an extent that it was no longer formless and phaseless qi, but a substantial state visible to the naked eye.

"There is such a boulder in the world, even if it is a hundred, a thousand times the spirit stones added together, and together they turn into aura, it is not as good as one percent of this boulder!" Wei Wuji withdrew from the shock and looked around secretly.

There was no danger around, and Wei Wuji quietly probed his divine consciousness and mind towards the round boulder.

It is estimated that he felt Wei Wuji's divine consciousness and intent, and the boulder suddenly changed. All the phantom fluorescence, as well as the aura that emanated, snorted to the ground and was included in the boulder.

In an instant, the boulder's light converged, and in the blink of an eye, it turned into an ordinary stone.

If the shock just now made Wei Wuji dumbfounded, the changes in the boulder now made Wei Wuji look in a trance, and he almost suspected that he was dreaming.

"This ...... How is this possible? Could it be that this stone is a living spiritual thing?"

Wei Wuji cleared his mind and took a closer look at the boulder again. There is not the slightest mistake, it is a stone, there is not the slightest sign of life.
