The three of them were looking for Du Hei's traces, but half a day passed, but they had no clue at all.

At this time, most of the physical strength was finally consumed and we had to rest.

The three of them stopped and began to rest.

At this time, Du Hei in the mountains also completed the hunting of the second ferocious beast.

Du Hei is very satisfied with this efficiency.

He felt that he was lucky.

The ferocious beasts I met were all the more unique.

He did not gather a large number of first-level beasts as his younger brothers.

Ferocious beasts like monkeys, wolves, and dogs usually have a group of little brothers around them, which is difficult to deal with when they reach the second level.

But what he met was a cheetah type and a bear type.

He happily cut the bear's paws, cut off the bear's gall, and put them in the package. Du Hei did not stay there for a long time, but continued to go towards the depths of the mountains.

Deep in the mountains, the trees gradually became taller.

From more than ten meters to twenty or thirty meters, to towering trees, almost completely obscured the sunlight.

The surroundings became a little dark, and it became a little weird.

Du Hei walked forward.

Soon, he discovered something was wrong.

After a full ten miles down, there was no sound coming from the surrounding area. It seemed that it was like a quiet jungle.

This is not very normal.

He had already figured out some rules. Under normal circumstances, the territory of a second-level ferocious beast was only a few miles at most.

After all, after the revival of spiritual energy, humans lost their dominance, the reproduction of the world's creatures is not disturbed, and the number of ferocious beasts is extremely exaggerated.

Many ferocious beasts were born in a nest of several cubs.

Therefore, in fact, the living space of ferocious beasts is also compressed.

Unlike before, a tiger can control everything in a jungle.

It is not surprising that there are several ferocious beasts of the same level in the jungle now.

It is precisely because of this situation that it is not particularly easy for humans to hunt ferocious beasts.

After all, the battle produces movement and it is easy to attract other ferocious beasts to surround them.

There are many factors to consider when hunting ferocious beasts.

Even like Du Hei, he usually doesn't dare to trouble the second-level high-level ferocious beasts.

These are all, he is already an exception.

In such a huge area, without any movement or stillness, there is usually only one situation, that is, there is the strength of a ferocious beast, which far surpasses the rest of the nearby existences.

This kind of transcendence is a crushing transcendence.

Otherwise, even if there is a difference, as long as it is not too big, this situation will not happen.

"A third-level ferocious beast!"

Du Hei's heart tightened.

In this case, he had only one idea, which was to quickly leave this area.

However, this idea only lasted for a moment.

Du Hei, when he left this area, saw a cave.

Moreover, this is not an ordinary cave.

The cave is deep and dark, but at the entrance of the cave, there are clear existence and residues of human buildings.

Moreover, in the cave, Du Hei felt the breath of spiritual power.

In just a moment, he had a guess.

This place should be an abandoned spiritual mine cave!

Mines, generally speaking, naturally exist in wild areas.

If you want to mine, you must be able to do your work in the wild.

When working in the wild, there is naturally the danger of being discovered and attacked by ferocious beasts.

Even if humans use hidden formations to cover the mines, it is not foolproof.

If it is a mine cave, it is worth a huge amount, and there will naturally be strong people to guard it.

But if a mine is no longer valuable, humans would not take such a big risk.

This is obviously the case here.

A mine with little value, but perhaps after years of baptism, some spiritual ore has been born again.

Du Hei's heart started to beat pounding at this moment.

This is a great opportunity.

If the amount of spiritual ore left inside is quite large, then you will be rich.

But at this time, what was before Du Hei was a choice.

There are very likely third-level ferocious beasts here.

Moreover, no one is sure whether the third-level ferocious beast will appear in the mine cave.

However, this hesitation did not last long.

Du Hei decided to investigate.

He is a summoner after all.

There is no need to take risks by yourself when you investigate.

This is one of the biggest advantages of summoners.

This kind of opportunity must not be missed.

Soon, Du Hei slowly summoned.

Ice Bird.

The summoning technique was strengthened twice.

This is the summoning skill he used as a mat during the holidays.

When he was promoting the blue quality, his successive failures provided him with a lot of enhanced experience points.

It was already falling to what it was before it was strengthened.

Later, Du Hei considered that he was indeed a reconnaissance skill, so he simply strengthened it to the top quality of white.

At this moment, under the strength of his second-level intermediate level, the summoned Ice Bird also has the strength of the second-level intermediate level, but it is not very strong.

But in terms of speed, it is not slow.

With the ability to fly and take on reconnaissance missions, it is perfect.

After a blue bird the size of a palm was summoned by Du Hei, Du Hei ordered the velociraptor to be alerted, and then there was a spiritual link.

When the spirit is linked to the Ice Bird, Du Hei is equivalent to transforming into the Ice Bird and flying towards the mine cave.

The mine is a bit deep and even darker.

The broken lighting device is vaguely visible at the top.

After flying hundreds of meters inside, Du Hei was extremely surprised at this time.

On the ground, there were some ore that made him extremely familiar with.

Iron ash ore.

Roughly speaking, at least thousands of iron ash ore are piled up on the ground.

On both sides of the mine cave, there are still some unmined ore.

This way, it is extremely clear at a glance.

This is an iron ash mine cave.

However, the mining reached the end and was attacked by ferocious beasts, so it simply did not retake the place.

After all, the accumulated ore on the ground, plus the unmined ore in the stones on both sides, is probably only a few thousand yuan, and the value is only one million yuan.

And to maintain mining of a mine in such an area, the cost will definitely be quite large.

Obviously not worth it.

So this place was abandoned.

But this amount is a considerable income for Du Hei.

Even if the ore that is still embedded in the rocks is not mined, it will be useless to just pick up the scattered on the ground!

Du Hei's heart moved. At this moment, suddenly, a strange sound came from Bing Bird's ears that were linked to the spirit.
Chapter completed!
