After Zhang Fan entered the light curtain, the communication with the outside world was completely interrupted.

But that's not a good thing for him.

In this way, after he discovers the power stone, no one will know how much he will put in his sub-biological space.

Although this is indeed a bit inauthentic, look at the people outside, all of them are actually ghosts. How many of them are genuinely interested in getting the power stones and sharing them with you?

At this time, Zhang Fan opened the nano watch and scanned it.

The scanning range of the nano watch can reach a radius of ten kilometers.

Just finished scanning this place.

Soon, a three-dimensional map was presented in his retina.

I saw that the terrain here is a huge circular open field.

In the very center of the circular open field is a crater.

This crater is supposed to be an active volcano.

The volcano is constantly spewing magma out.

The red light that Zhang Fan saw just now should be the light emitted by magma.

It's just that because this is the bottom of the water, the amount of magma eruption is not large, and it will be cooled down quickly.

In addition, it seems that this place and the four ponds are not connected at all before.

So from the outside world, there is nothing abnormal at all.

Zhang Fan didn't understand until this time why the word fire was not engraved under the four pools.

This active volcano is already on fire.

and other four characters of gold, wood, water, and earth, which just form the five elements.

The five elements are mutually reinforcing, so that the balance is maintained here.

Although Zhang Fan doesn't believe in these, but judging from the current situation, it seems that there is a little bit of truth in this.

Zhang Fan looked at all the details on the three-dimensional map.

On the surface, there don't seem to be any power stones here.

As he dived in the direction of the volcano, he said, "Do a deep scan." ”

Soon, the results of the scan came out.

After searching all the details, there was a discovery.

Halfway up the mountain, under the rock formations, there is a tombstone.

Who would bury their ancestors halfway up the mountain?

Zhang Fan glanced down at the energy detector.

As he got closer to the volcano, the numbers on the detector grew larger.

Soon, it has reached more than 50.

At this time, Zhang Fan had already come to the volcano.

At this time, although the volcano is not too big, it is definitely not small.

According to Zhang Fan's estimates, the diameter of the crater is almost more than 200 meters.

At the foot of the mountain, the diameter reaches about 5 kilometers.

The height of the volcano is about 300 meters.

At the crater, hot magma is constantly spewing out.

However, after the magma erupts for more than 50 meters, it will fall down and gradually flow down around the crater.

Zhang Fan didn't have time to appreciate the wonders of this underwater volcano, so he directly followed the map and came to the halfway point of the mountain.

According to the scans of the nanowatch, the tombstone is one meter below the rock formation here.

At this time, the magma flowing down from the mountain pass was less than twenty meters away.

If it's a few days late, the lava might have already flowed here.

From the data on the energy detector, the energy value has reached 93.337.

It seems that the power stone must be in the tomb under this rock formation.

Perhaps someone buried their ancestors on the mountain before.

But I didn't expect the volcanic eruption to bury the ancestors' Murong.

Zhang Fan didn't have time to think about it, and quickly dug with the shadow blade.

After more than half an hour, the tombstone was finally dug up.

The words engraved on the tombstone are not like the ancient seal characters carved on the bottom of the pool outside.

It's a book.

Although it is traditional, Zhang Fan doesn't understand it very well, but the nano watch can be translated.

The handwriting on it is: Father Yang went to the tomb of the sick.

Next to it is a line of small words: Ziyang stands without illness.

From this tombstone, it seems that there is not much information to be seen.

At this point, the magma above was less than fifteen meters away.

It looks like the magma is flowing down a bit faster.

Zhang Fan's heart sank.

Could it be that the volcano is about to erupt?

I've heard it before, and according to the analyzed data, the volcano around Wudalianchi should erupt more than 50 days later.

But no one knew that there was a volcano hidden under the water.

And the volcano is already erupting, but there is no large-scale eruption.

Now it seems that this underwater volcano could erupt on a large scale at any time.

Looks like we're going to have to hurry.

Zhang Fan didn't dare to think about it anymore, and hurriedly excavated the tomb below.

Fortunately, after digging for a while, the rock layer above has been excavated, and the bottom is actually earthy.

He digs a lot faster.

It took about an hour, and when the magma above was still about five meters away, the tomb was finally dug up.

In the tomb was a pair of bones that had long since been shattered.

Next to the bones, the one that emitted a glimmer of light was indeed a power stone!

It's just that to Zhang Fan's disappointment, there are not as many energy stones as he imagined, only two.

But even if it's two power stones, it's worth it.

After all, that's the equivalent of 10 billion.

It took more than a month to get 10 billion.

Even for an intermediate martial artist, it was not a small amount.

Putting these two power stones into the sub-biological space, Zhang Fan found that in this small tomb, there was also a book.

Zhang Fan's heart is not good.

This book is soaked in water like this, so it's not over?

He hurriedly and carefully picked up the book.

The book was stronger than he had imagined, and it didn't seem to be fragile from being blistered, nor from being buried in a tomb for hundreds or thousands of years.

And it looks very leathery, like oiled paper.

The book is obviously an ancient book, thread-bound.

The book is not turned from right to left, but from left to right, as in ancient times.

Zhang Fan didn't have time to read the content carefully at this time, only looked at the cover.

On the cover, there are three more illegible fonts.

It doesn't look like a seal script, it's not an official script, and I don't know if it's an oracle bone inscription or a golden script.

Fortunately, there are nano watches, and through the translation of nano watches, Zhang Fan finally understood what the book was called.

It's called - "The Secret of Longevity".

Belch......

Zhang Fan was directly speechless.

This looks like something out of fantasy.

What kind of society is it now, how can anyone still believe in this kind of bird thing?

But think about it, the owner of this tomb should be hundreds or even thousands of years ago, I believe these are understandable.

And his son didn't believe in it anymore, otherwise he wouldn't have been able to use it to bury him.

Of course, it is not excluded that his son does not know the words on it, so it is naturally impossible to know that this is the so-called "Recipe for Longevity".

Although Zhang Fan doesn't believe in this thing, this thing can be regarded as a cultural relic.

If you take it out and sell it, you can sell it for a lot of money.

And this thing has been in the tomb for almost a thousand years, and it can be intact without any protection.

There is no change in the water either, which in itself shows that the material of the book is special.

Therefore, Zhang Fan directly included this thing in the sub-biological space.
