On this side of the Maple Moon Continent.
Ji Fengyao, Xi Que, An Zijin, Lu Yang, and Zhuang Shaoze have already dug up the layer containing the high-grade spirit stones.
They dug vertically downwards, and the diameter of the area they dug was no more than five meters. Therefore, there were still many low-grade and mid-grade spirit stones buried in the soil and rocks on both sides. It would take more manpower and time to finish digging them out.
Digging vertically downwards was Ji Fengyao's idea.
Firstly, she wanted to verify whether this mine was indeed a man-made spiritual mine;
It now seems that this mine is most likely man-made, because the quality of this superior layer is also very similar.
Furthermore, below the superior-grade spirit stone, there is no quality transition; the next level is the ultimate-grade spirit stone!
Similar to the qualities mentioned above, the fault lines are very obvious!
“Miss, this spirit mine…” Xi Que had mined spirit mines in Mangshan with Ji Fengyao.
Even though she was usually carefree and oblivious, she noticed something was amiss.
Natural minerals wouldn't suddenly improve in quality like this, going from low-grade mixed with medium-grade to all medium-grade; then from medium-grade mixed with high-grade to all high-grade, and so on, gradually moving upwards.
But the spirit stones here are not only arranged in an orderly and neat manner, but their quality is also so similar that they don't seem to be natural at all.
"Don't make a sound," Ji Fengyao told the magpie through telepathy.
Xi Que thought she still didn't trust An Zijin and Lu Yang, so she just gave a soft "hmm" and didn't say anything more.
Anyway, whatever her mistress says goes, and she completely obeys and trusts her mistress unconditionally.
At this moment, An Zijin suddenly stopped digging and pretended to listen carefully, asking, "Miss, Luyang, did you hear anything?"
"What?" Lu Yang also stopped and turned his head to look at An Zijin in confusion.
Ji Fengyao, Xi Que, and Zhuang Shaoze also stopped digging, and the isolation array immediately fell silent.
The group carefully discerned the sounds around them.
Above, there was the faint sound of the waterfall crashing down, and the sound of water flowing slowly through the mud.
Xi Que and Zhuang Shaoze could only hear these things; they were completely unaware of anything else.
But besides these, Ji Fengyao and Lu Yang both heard faint thunder and bursts of explosions coming from a very, very far place below them.
It's like someone is undergoing a tribulation, or like many people are fighting?
Ji Fengyao, Lu Yang, and An Zijin all looked puzzled.
Is someone undergoing tribulation deep underground?
Are people fighting?
Were they hallucinating?
Or is there another unknown world beneath this plane?
"Miss, shall we continue digging?" An Zijin asked with a strange expression.
"What's wrong?" Xi Que and Zhuang Shaoze both looked puzzled.
“It looks like someone is undergoing tribulation or fighting down there,” Ji Fengyao said, finding it somewhat unbelievable herself, but she continued, “Keep digging and see what’s going on. But be careful, in case there’s an illusion array down there.”
The group nodded in agreement, and upon hearing the words "illusion array," they all calmed down a bit.
As the name suggests, an illusion array is a formation that can create illusions. It can conjure up even the strangest sounds, let alone thunder or fighting. Therefore, it's not surprising that they are hearing these sounds now.
But when they finished digging out the top-grade spirit stone layer, they were stunned when they looked down through the semi-transparent spirit liquid layer below.
Even the well-informed Ji Fengyao couldn't believe her eyes.
