After spending the night in a low depression near the cliff, the next morning, the dragon's nest on the cliff was again filled with the sound of sharp air currents and a loud dragon roar.

Immediately, this legendary-level demonic beast slowly flew away from the lair, circled in the air at an altitude of five thousand meters, and left unhurriedly.

It wasn't until it disappeared for nearly five minutes that Fang Jin dared to come out of his hiding place.

Sure that the other party would not return for a while, he quickly moved and prepared to sneak into the dragon's lair of this legendary demonic beast. Scout the terrain first, and follow the change to see if you can find anything good. After all, as in the movies, the dragon's lair is full of treasures and magical items.

However, if you want to quietly blend into the dragon's nest without leaving any breath, it is also a delicate job.

Fang Jin's spatial equipment contained a medicinal powder that could cover his breath, and he first sprinkled one on himself, and then summoned the Black Flame Storm Griffin from afar, and sprinkled it all over his body, before letting this trembling griffin send himself to the dragon's nest at the top of the cliff.

The dragon's nest, located at the top of the cliff, carved a space in the cliff that was more than thirty meters wide and at least hundreds of meters deep. He noticed that the rock layer at the top of the dragon's nest was at least ten zhang thick, and it was by no means easy to shake. If you can take advantage of the time when the dragon of destruction is left in the nest**, you can suddenly kill it and block it in the dragon's nest......

This is undoubtedly a very tempting and at the same time very feasible idea.

Whether it will work or not depends on the next investigation.

With a wave of his hand, the Black Flame Storm Griffin flew away from here, helping himself watch the wind in the air, and Fang Jin stood still on the stone platform at the entrance to the dragon's nest on the cliff. After looking into the deep passage a few times, he didn't find any other problems, so he crept in.

After the first few tens of meters, there was a small bend in the passage ahead, and you could vaguely smell the unpleasant smell left by the Black Dragon of Destruction, as well as the terrifying aura for creatures below the Golden Rank.

Rounding this curve that is not too large, the view ahead suddenly opens up.

At the end of more than 100 meters, a huge and spacious cave appeared in front of him. In the central place where the black dragon rests, some messy decorations are also made with the unique "aesthetic taste" of the dragon clan. Other than that, there was nothing left except for a large pile of burned ashes that had been left over from the aftermath of eating.

There are no mountains of treasure as imagined, nor powerful magical equipment.

This inevitably made Fang Jin a little disappointed that his illusions were broken.

"Wait...... That big rock! ”

After a glance and found nothing, and was about to evacuate in such disappointment, Fang Jin inadvertently glanced back, and suddenly saw a large black stone that was randomly thrown in the corner.

Look at the weight, at least half a ton!

Familiar!

Very familiar!

At first, he only felt unusual, but the more he looked at it, the more familiar it became, and he realized that there must be some origin of this stone.

After pondering for more than ten seconds, Fang Jin suddenly remembered something, and his face changed.

This is not a metal ore that is necessary for forging high-tier Legendary equipment...... Netherworld Gold Iron Ore?

With exceptional hardness and wear resistance, the forged heavy armor and plate armor equipment often comes with extremely high durability and basic physical defense values. The problem is that before this, when the Astral Black Merchants collected this ore, the amount was denominated in a small piece (about two to three catties). Because of this, he was accustomed to small impressions, so he didn't recognize it at the first time.

And even such a small piece can easily be sold for tens of thousands or even hundreds of thousands of gold coins!

The Netherworld Constant Gold Iron Ore in front of me......

Fang Jin had previously judged that it weighed half a ton, which was roughly measured by the density and weight of ordinary rocks. In fact, the density of Netherworld Gold Iron Ore is at least four or five times that of ordinary rock. In other words, this piece of high-purity ore that was discarded at random in the corner of the dragon's nest and was purely composed of Netherworld Constant Gold Iron Ore weighed at least more than two tons, or even nearly three tons!

Based on the price of at least 30,000 or 40,000 gold coins per catty......

Two or three hundred million gold coins?

Fang Jin's heart beat violently incorrectly, and he didn't expect that a seemingly inconspicuous piece of ore in the dragon's nest could be sold for such a sky-high price!

Even with the wealth of the Salvation Guild, hundreds of millions of gold coins are unimaginably astronomical.

No, no, no!

Netherworld gold iron ore can be so valuable, it is based on the fact that the production is very small. If a few thousand kilograms are suddenly shipped at once, then unless the treacherous black businessmen collectively have a convulsion, they will definitely try their best to lower the price. At that point, a five-ten-fold price reduction is possible.

Therefore, even if you succeed yourself, in order to maximize the value, you will definitely not be able to realize it all at once.

Most of them can only be withheld for forging by their own guild members, and a small amount of them can be shipped slowly. Only in this way can we ensure that its value is not discounted to the greatest extent!

But in any case, this is a treasure that can trigger a superpower war and make the ignorant professions scramble.

For a moment, Fang Jin planned to immediately open the mobile space and store it in the guild warehouse of the Rescuers' Guild Headquarters, the safest safe in the world at the moment.

But another worry is that in the mind of heaven and man are at war.

A voice told him that the inconspicuous black stone had clearly been discarded at random by the Dragon of Destruction. Even if it disappears one day, as long as there is no obvious breath and traces left, the other party will most likely not care.

But another voice reminded him not to underestimate a legendary beast with high intelligence in any detail!

If the dragon of destruction is alerted in advance, the variables and risks of follow-up actions will increase indefinitely. What's more, this place is located on a 5,000-meter cliff in the hinterland of Kunlun Mountain, and it is located in the lair of legendary magical beasts, it is almost impossible for anyone else to break in, and it is very safe in itself.

Even if you take 10,000 steps back, someone really broke into this place, and they have a deep vision and keen attention, and they can detect the black ore in this corner at a glance. In the absence of space equipment, there is no way to take it away with a few tons of storage backpack that comes with the system!

Therefore, before he killed and destroyed the Black Dragon, he didn't need to worry about the Netherworld Constant Gold Iron Ore going to another family.

However, having said that, this is a super ore worth hundreds of millions in theory after all!

It is difficult for anyone to be absolutely sane when such a huge fortune is suddenly involved, and it is within reach.

But in the end, Fang Jin still restrained his impulse with great perseverance, and without even reaching out to touch this piece of ore, he retreated.

After making sure that he had left no traces, he immediately harnessed the Storm Griffin to turn around and run wildly, heading straight back to the Shu County headquarters.

It seems that the timetable for the crusade against this legendary monster is bound to be advanced!
