That is a sign that it contains black iron, a first-order metallic material.
However, such training resources are no longer in Li Qingtong's eyes.
It's just first-order black iron, how much spiritual stone is it worth?
Within the intricate tunnels, Li Qingtong directly chose the shortest path into the core area, not even taking care of the centuries-old elixirs that existed in some tunnels.
Soon, an underground circular space with a diameter of nearly one hundred feet appeared in front of Li Qingtong.
There had been exploration in Lingding for a long time, and Li Qingtong had never been too amazed by this place.
His eyes only need to focus on the center of this space.
There is a mushroom-shaped rock there. The upper part has been separated from the top of the space, leaving only a palm-sized rock root below.
The whole rock mushroom is about ten feet high, and the umbrella cover is almost nine feet in diameter.
The reason why things of such a shape attract Li Qingtong is certainly not because of their mysterious appearance.
This rock mushroom was gnawed out by the black beetle from the most elite area of the black iron vein for who knows how many years!
The remaining part is the core part of the entire mineral vein.
In the black beetle's broken soul memory, every time it gnaws at this part, it can only chip away at a negligible amount.
Black iron ore mother!
It contains a mass of black iron ore.
This thing can only produce low-level materials such as black iron if raised, and its help to Li Qingtong is very limited.
However, Li Qingtong still took the trouble to go there.
The purpose is to add a more complete system of rules and order to the Lingding space.
It's always good to have more sources of minerals.
There is another reason...this mineral source is different from the ordinary black iron ore source and mother ore.
Its mushroom cap also gave birth to a spiritual eye thing!
This is companionship!
For Li Qingtong, any spiritual eye object at this moment is a huge help.
At this point, Li Qingtong no longer needs to take the initiative to inspire.
The spiritual cauldron released its means, and a layer of mysterious aura spread across the entire mining area like water waves.
When reaching the edge area, these spiritual lights suddenly retracted.
A scene happened that even Li Qingtong didn't understand.
The dark iron essence scattered throughout the mining area was recovered along with the aura.
In just the blink of an eye, those spiritual lights had already enveloped the essence of the mushroom in the mine tunnel.
All the Xuantian essence carried by the spiritual light retracted from the entire mining area is attached to the mushrooms.
The next moment, a collection of spiritual light was released.
This mushroom has disappeared!
Li Qingtong's body turned into a gust of wind and fled within the mine tunnel.
It was a hundred times faster than when I entered, and in three to five breaths I had already covered most of the distance.
The core of the mine collapsed!
This caused the entire mining area to collapse, and the mining area that had been drained of its spiritual essence seemed to turn into an area of sand.
Those mine tunnels can no longer be overwhelmed.
From a high altitude, it looks like a sandy vortex has appeared in the entire area.
A huge quicksand pit formed in a short period of time.
In the edge area, Li Qingtong emerged from the falling quicksand.
It was still a step too late, but he was already over the embarrassing situation now, so he didn't need to pay attention anymore.
The breath all over his body shook, and his whole body was shot out like a sword.
But just as Li Qingtong was flying in the air, a sudden thunder and lightning force fell on his head!
That's not all.
Centered on the collapsed tunnel, calamity clouds began to accumulate in the sky within a radius of hundreds of miles.
A power that is different from all the catastrophes Li Qingtong has experienced or experienced while in a dream state!
"It's just the power of the Heavenly Tribulation, how can there be 'heaven' in such a space!" Li Qingtong's words were slightly contemptuous.
After all... the spirit cauldron itself is moving in this direction as it nurtures the void.
Opportunities time after time brought about earth-shaking changes in Lingding.
But the current inner space of the Lingding Cauldron can still only be regarded as a secret space.
It is still far from the definition of "heaven and earth".
The area of the secret realm on this island is unknown to be many times larger than the inner space of the Ling Cauldron, but it is just bigger, and spiritually it is far inferior to the secret realm space inside the Ling Cauldron.
For a moment when Li Qingtong was in a daze, the specious aura of heavenly calamity from the outside world suddenly became stronger.
I don't know if he was angered by what Li Qingtong said to himself.
A bolt of thunder descended.
Li Qingtong felt even weirder.
The number of catastrophes he has experienced is so great.
That can be said to be extremely experienced. Even the old monsters in the Nascent Soul stage are far inferior to Li Qingtong in terms of overcoming tribulations.
At the moment when the tribulation thunder landed, Li Qingtong felt a completely different aura of the power of law and order.
Before he could do any more sensing, the appetizer Jie Lei had already been absorbed by the Ling Cauldron.
Let Li Qingtong's unexpected changes appear.
This specious pseudo-celestial disaster brought great benefits to the Creation Spirit Cauldron.
It doesn't give the Lingding more power, but it expands something that even Li Qingtong can't explain.
Li Qingtong resisted the force of the thunder and flew to the edge of the bunker.
It was like a greedy demon appeared at the bottom of the pit, devouring everything crazily.
The bunker continues to expand and seems never-ending.
The second calamity thunder fell.
There was no need for Li Qingtong to initiate any means, Lingding could not wait to capture it.
In this way, he passed through nine special small tribulations with joy and joy without any danger. Li Qingtong rushed to the next monster lair with a sense of loss.
He had already guessed that the act of collecting the spiritual eye thing and the mineral source thing should have angered the 'spirit' in this secret space.
It seems that the next move should be as careful as possible.
Li Qingtong occasionally picked up some small surprises on the road, but the high-level monks from the Tianbu Dao Sect outside were already a little confused.
Just now, the extinct light spot reappeared with a large swath of brilliance.
Of course not all, but as many as two-thirds!
Have the dead come back to life?
The monster lair in the form of a mouse is placed at the end, not because it is the richest and is the finale.
But because this nest is the most barren!
A rocky mountain that was riddled with holes contained countless monsters, large and small.
As for the elixirs and plants... there isn’t even one ten years old!
Li Qingtong didn't come here just for the magical medicine or spiritual plant.
He released the white jade centipede.
The white jade centipede, whose appearance gradually changed from a ferocious state to a refined one, got into the rat's nest.
One after another, rats and mice were devoured by it.
When the white jade centipede was almost full, it deliberately showed its whereabouts.
The entire rat nest rioted.
Next, of course, the Ghost-faced Seven-Star Spider and the Sea Snake began to eat the rats and rats that had been led out of their nests.
