Zhou Shu put away the small roll and thought thoughtfully.

It seems that most of the caves in this cave do not have demon beasts, but some kind of spiritual objects rich in aura, which is very good news and worth exploring.

Zhou Shu took out a few spirit stones, set up a simple spirit gathering array, and continued to recover spiritual power.

If you decide to go in, you have to be prepared, your physical condition must be perfect, and there are no demon beasts, it doesn't mean that there is no danger, most of them have traps and other things, so be careful.

Cultivators generally use the Spirit Gathering Array to restore their spiritual power, and then cooperate with auxiliary pills to speed up the recovery. Of course, there are also pills that can quickly restore spiritual power, the kind that can also be used in battle, but most of that kind of pills are above the third order, and the price is high, so it is not something that ordinary cultivators can afford.

Zhou Shu can't afford it.

About half an hour later, Zhou Shu walked towards the entrance of the cave.

The Cloud Chasing Sword opened the way, carefully cutting through the surrounding dirt and stones, and walked slowly.

The cave is very deep, and the more you go down, the narrower and narrower it gets, and you walk nearly a hundred zhang, and the entrance to the cave in front of you is only a few feet wide.

It's a little strange, maybe this cave isn't an entrance, more like a makeshift vent or something.

Zhou Shu was more cautious, and his steps became slower and slower.

After walking for a while, a few bright lights suddenly appeared in front of me, apparently reaching the end.

Enlarged the entrance of the cave, Zhou Shu looked forward, his eyes suddenly froze a little, he finally understood why Xiao Roll was so eager.

Here, it turned out to be a spiritual stone vein.

For Xiao Roll, the spirit stone is the biggest temptation that cannot be resisted.

In the naturally formed cave, there is a large open space, and there is a crystal light shining everywhere, both around and up and down, all of them, illuminating the cave as if it were day.

The pure spirit stones, like the stars on the horizon, are half-hidden in the rocks or soil, emitting a thick or faint light.

I can't imagine that there is such a place hidden under the ruins.

There must be a spiritual vein in the spiritual stone mine, and the spiritual energy here is very strong, much better than that of the Shaking Wind Garden, and there should be a third-order spiritual vein below.

The discovery of the spirit vein and the spirit stone mine is not a small opportunity.

Zhou Shu put away the excitement in his heart and continued to walk inside.

After walking for a short time, he made other discoveries, there were traces of fighting in many places, and there were also many broken bones and abandoned magic weapons on the ground.

He walked over to the pile of bones and tried to pick them up, but as soon as the bones touched his fingers, they quickly scattered into ashes.

Obviously, these white bones have been lying here for I don't know how many years, at least thousands of years, have long been weathered and withered.

Those magic weapons are similar, although they are not weathered, but they have no reaction to the spiritual power input by Zhou Shu, obviously because they have not been used by cultivators for too long, the spiritual energy has gradually dissipated, and they have lost the characteristics of magic weapons, and they have lost their value as materials.

Pity.

Zhou Shu felt regretful, at a glance, there were at least a dozen storage bags and various magic weapons, but none of them could be used.

In addition to the magic weapon, there are also many broken formation talismans on the ground, which are quite mysterious from the rune pattern, most of them are formations that can even be blocked by foundation building realm cultivators, but after so many years, the formation talisman has long lost its effectiveness, and the formation no longer has any effect, and nothing can stop it.

The years are ruthless, and thousands of years will defeat many things and turn them into nothingness, such as magic weapons that no cultivators use, no array talismans that are replenished by spiritual power of spirit stones, cultivators who have not reached the Yuan Infant Realm, and so on.

But it's just a low-level thing, if it's a high-level thing, it can not only resist the invasion of time, but can continue to grow. For example, magic weapons, magic weapons of the fifth order and above, without the need for cultivators to use them, they can absorb the surrounding aura to nourish themselves, as long as they are placed in a place with aura, they will look like new no matter how long it takes.

The magic weapon is like this, and so is the cultivator, if he breaks through the Yuan Infant, he will only make his cultivation more profound in thousands of years, instead of losing to the ruthless years.

Zhou Shu sighed for a while and continued to walk deeper into the cave.

Nearing the end, he stopped.

There was a pile of white bones in front of him, half-leaning on the cave wall, there were many obvious scars on the white bones, and even a left hand was missing, and at its feet, there was a crystal bone jade staff.

The bone jade staff is about three feet long, as thick as a child's arm, the whole body is turquoise, the texture is extremely exquisite, and the top is inlaid with a deep red gem like fire.

The aura is exposed, the brilliance can be seen, if it is a magic weapon, it obviously still retains the original function.

Is it a high-level magic weapon?

Zhou Shu felt a burst of ecstasy in his heart, and reached out to pick up the bone jade staff.

Put it in his hand and look at it carefully, input a trace of spiritual power, and suddenly felt disappointed, this will definitely not be a high-level magic weapon, and it is not even like a magic weapon, because the spiritual power in it is very thin, and even he can easily enter and master it.

If it is a high-level magic weapon, with the spiritual power of Zhou Shu's Qi Refining Realm, it is impossible to enter the magic weapon at all, and it is impossible to use it.

But it is strange that this bone jade staff can stay here for so long and withstand the invasion of time, most of which are for other reasons.

His gaze fell on the gem at the top of the bone jade staff, the gem was crystal clear, like a spirit stone, but the surface was covered with a layer of faint white smoke, and there seemed to be a raging and eager flame in the middle of the continuous burning, vaguely revealing a lot of enchanting allure, the magic was abnormal, people couldn't help but want to touch, want to take it as a treasure.

But Zhou Shu looked at it, and did not enter the spiritual power temptation, nor did he touch it with his hands.

The gem gave him a strange feeling, which he rarely felt, and every time he felt it, there was always danger behind it.

Put it away first, and talk about it later when you get back.

He stood by the bones and looked back.

Looking at the dazzling spirit stone mine, the white bones and magic weapons everywhere, and the traces of fierce battles on the cave walls, Zhou Shu unconsciously made up pictures in his brain.

Thousands of years ago, this was originally a small family, and they relied on spirit stone mines and spirit veins to establish a territory and gradually grow and develop. But one day, he was broken in by a powerful enemy who wanted them to surrender and hand over the spirit stone mine. Naturally, they refused, and as a result, the murderous enemy destroyed the family domain and turned it into ruins.

The small family finally introduced the enemy to the most heavily defended spirit stone mine, where they fought to the death, and finally the enemy died, but the family also perished.

It's a sad and heroic story.

Zhou Shu put away his thoughts and began to carefully observe the spirit stone mine.

He had only been to the Spirit Stone Mine once, and that was when he was in Wufumen, but the Spirit Stone Mine in Wufumen was a little smaller than here, only second-order. Looking carefully at the past, most of the spirit stones here are medium-grade spirit stones, and there are very few low-grade spirit stones, and there are a lot of them, just exposed, there are at least forty or fifty thousand.

There are no high-grade spirit stones, and it is impossible for a third-order spirit stone vein to produce a high-grade spirit stone.

This wealth is not small.

But it's not easy to get, it's a vein instead of a dug spirit stone.

Mining spirit stone mines requires a lot of manpower and energy, digging spirit stones is not the same as digging other minerals, the process is much more complicated, spirit stones are very small and buried deep in the rocks, it is easy to break, if you are not careful, the spirit energy in the spirit stones may escape or even explode.

Zhou Shu thought for a while, and soon had an idea.
