The more she walked in, the more Wang Zi's brows wrinkled, this endlessly made her a little upset, so she simply flew directly with the sword, and suddenly the speed was raised.

She didn't know how far she had run, anyway, the deeper she went, the more full of aura became.

Suddenly, her mind noticed that there were more glowing crystalline objects on the walls on both sides of the walls, the largest ones the size of a fist, and the smaller ones the size of a grain of rice.

Spirit Stone!

Wang Zi instantly recognized what this thing was, and was slightly startled.

At present, there is only one known source of spiritual stones on the earth, and that is the occasional eruption of Yangzhou Ding under the Huangpu River.

If you let people know that there will be a large number of spirit stones in the depths of this cave, it will definitely make people crazy.

The spirit stones inlaid on the walls on both sides are not only a little, the more they go inside, the more they continue to go inside, although they are getting fewer and fewer, they are getting bigger and bigger, and the largest one she has seen that there is an adult's head big.

Could it be that this is a spiritual vein?

Wang Zi guessed this in his heart, and it was extremely likely.

The spirit stones on the walls on both sides do not seem to be artificially inlaid with them, but seem to have grown on their own, and have been bred after tens of millions of years.

Wang Zi guessed that this cave may have been excavated in ancient times, specially used to collect spirit stones, after the pre-Qin period, the monks disappeared, and this cave was sealed, and it has not been seen again until now.

This cave has been nourished by spiritual energy for many years, and the surrounding cave walls are extremely hard, so it has not collapsed for thousands of years.

But then again, since this is a spiritual vein, how could that person disappear so well? And before the third wave of people disappeared, there was a final image, which was a dilapidated mountain village, and the buildings were still in ancient shape.

Is there a cave in the depths of this cave? Everything is full of unknowns, but it also makes Wang Zi curious, is there another adventure here? Judging by her luck, it shouldn't be too bad.

Found out, that's ...... End!

I don't know how far it flew, but when it was put on the surface, it was estimated that it could cross the entire country.

Sure enough, at the end, it was a spiritual vein, a spiritual vein rich in spirit stones, which seemed to have been mined half, and half of it had not been mined.

Although Wang Zi couldn't see how much of this half there was, it was at least enough for all the awakened people in the entire country to consume for a long, long time. It is impossible to estimate how long Wang Zi will be, but there should be hundreds of years.

However, the premise is that they have the ability to mine, after all, the spirit stone is a rich spiritual energy compression, which has been condensed over an unknown number of years, and it is much harder than diamond.

In the cultivation realm, there are special tools for mining spirit stones, and as for how people will mine on this planet, it depends on their brains.

However, since he is here, he naturally can't go home empty-handed, and he has to dig up at least a little bit of this spiritual vein.

As for how much to dig, it depends on her ability, with her Jindan realm, plus the help of magic weapons, she should be able to dig a batch.

Sacrificing the flying sword, under the command of Wang Zi, he suddenly flew out towards the spirit stone in front of him.

With a deafening sound, sparks flashed, and the spirit stone was slammed down by the flying sword, touching her Wang Zi's palm.

"Damn, why should I cut it so hard?" Wang Zi felt incredible, this spirit stone was even harder than she imagined.

Although she has spirit stones, she has never done an experiment of cutting spirit stones, and she only knows that spirit stones are very hard, but she didn't expect it to be so hard.

She cut the spirit stone once today, and she knew it.

MMP, do you want to do this, obviously a large spiritual vein is in front of her, but she is told that she can't take it away, and she feels that her life is gray.

It's okay if she didn't find this spiritual vein, but now that she knows it, she can't take it away, which makes her heart ache!

Her heart did hurt a little, firstly because of this spiritual vein, and secondly because the flying sword without a sword grid collided with this spiritual stone, and was actually knocked out of a small hole.

She has been raising this flying sword for so long, and she has long been associated with it, and now that the flying sword is injured, she is not comfortable. Fortunately, this is not a natal weapon, otherwise she would be comfortable.

There is another important thing, this flying sword and spirit stone can still be knocked out of each other, it seems that this flying sword is a little backward and needs to be refined.

Now that she has reached the Dan stage, her refining skills have increased significantly, and it must be easy to improve this levelless sword, and it is estimated that she can raise it to a level.

If you want to refine the flying sword, let's get this when you have time, and now her main thing is, that is...... What is it?

Oh yes, it's to save people, and see where those who are missing go.

But then again, it's all in the end, why haven't you seen those missing people? Not even the corpse was seen, let alone the last picture of the deserted village.

There seemed to be some strange secrets revealed here that Wang Zi didn't notice, and she couldn't help but fall into deep thought, thinking about all the situations along the way, to see if she had missed something.

What's missing? It seems that this way has come, and there is nothing wrong with it.

This is even more strange, it is even more strange that there is something strange about it, but it can't be discovered.

No, the silence in this cave seems to be too much, or rather, it's too quiet.

At this moment, Wang Zi is like Conan possessed, his brain is flying, and he will think about all the memories he passes by.

But she is not Conan after all, and she can't find Conan, let alone the name of the Grim Reaper Schoolboy, and she won't go anywhere to die.

Rubbing her eyebrows, this is the first time she has felt a headache since she cultivated immortals.

"It's the most annoying thing that needs to go through the brain, if only I could rely on my strength to speak, so that I can directly level A, why waste so many brain cells, now I have a headache to think about." Wang Zi muttered dissatisfiedly.

Looking at the spiritual veins in front of her again, she suddenly felt that there was no hurry to find someone, let's dig some spirit stones first. It's all here, she's not Yanagishita Megumi, there's no need to pretend to be HD, anyway, no one sees it here, she just digs it casually.

This flying sword, which has accompanied her since the opening of the light, is now being dug by her, and the sword body has a gap at a speed visible to the naked eye, and the sword body, which was originally clean and can be used as a mirror, also has a lot of large and small scars.

However, this spirit stone is a little small, but it is enough for Wang Zi to squander it for a while.

The flying sword had a lot of injuries on the spirit stone, and it was fed back to Wang Zi, making her a little uncomfortable and not feeling very comfortable, but she quickly recovered.

After collecting these dug spirit stones and the deformed flying swords into the Purple Mansion for warmth, Wang Zi remembered again what he was here for, obviously he was here to find someone to save people, how did he become a miner?

But then again, there's no clue at all, where is she going to start? I don't know where to start.
