And at this moment, as though she thought of something, Yu Zi Yu's gaze suddenly shifted to Qing `er as she spoke,"Since you're back, prepare to move the spirit stone mine tonight.”
"It's just moving, Master. We should be going underground, right?”
Nodding his head, Yu Zi Yu also agreed and said,""Go underground to prevent too much spiritual energy from leaking out of the spirit stone mine.”
As he said, Yu Zi Yu's gaze also pulled onto the mutated wild beast not far away.
A red firefox was lying on a huge rock, and a black buffalo was sleeping in front of him.
There were also the four giant wolves in the distance, as well as Bro Flattop, who was still baring his teeth.
Of course, that little golden monkey could also be considered.
With the eight of them and Qing 'er, they could easily dig a tunnel underground within a day.
Thinking up to here, Yu Zi Yu's countless tree roots that extended deep underground intertwined with each other, quickly turning into one.
Then,
"Rumble, rumble, rumble…"
As the earth shook, a flat ground not far from the ground was pierced through by countless tree roots, and a huge pit appeared.
"Using this hole, you can directly dive underground and then…Do you understand?"
"Naturally, I understand."
Smiling, Qing Er waved at the mutated beasts and led them towards the entrance of the cave.
And this was one of the benefits of the Extraordinary Era.
Their terrifying bodies, combined with their abundant spiritual energy, were enough to increase the efficiency of these mutated beasts in digging holes by more than a hundred times.
Now, with a change of perspective, Yu Zi Yu had already seen Qing Er bringing these eight mutated wild beasts straight into the spirit stone mine.
The Green Girl Giant Wolf occasionally breathed, and wind blades tore through the rocks.
The black bull, the Ox Demon, walked on the ground with its hind legs. Then, it charged forward for dozens of meters.
And because the ground was hundreds of meters deep, the settling of the earth for tens of millions of years was enough to support such a small-scale earthquake.
With that, the mutated beasts did not have to worry about the tunnel collapsing.
......
After a long time, a tunnel that was dozens of kilometers long had been dug deep into the ground.
At this moment,
"Stomp, stomp, stomp…"
With heavy footsteps, Qing 'Er had already brought the mutated beasts back to the depths of the Northern Universe Canyon.
However, to their astonishment, the depths of the Northern Universe Canyon seemed to have been hollowed out. There was an additional underground plaza that was hundreds of meters wide.
In the center of the square, there was a blood-colored plant that was slowly swaying.
"Master, this is…"
Qing 'Er was also surprised.
"While you guys are busy, I naturally won't be idle. Isn't it just digging a square with the help of the roots?”
As he said, Yu Zi Yu pulled his gaze towards the blood grass not far away and added,""The spiritual herb you brought back for me has not lost its spirituality. If nothing unexpected happens, it will be of great use to me.”
"You're welcome."
A knowing smile appeared on Qing `er's face as she waved her right hand.
A moment later, a pile of rocks that were faintly emitting a hazy glow appeared in front of Yu Zi Yu under the support of Qing Er's Mental Energy.
"Are these spirit stones?"
The tree root rolled up a fist-sized rock. Yu Zi Yu was also suddenly startled.
A very pure Spiritual Energy suddenly wrapped around it. Yu Zi Yu could vaguely feel the root expanding and contracting as if it was absorbing something.
"No wonder that silver centipede broke through so quickly. With the nourishment of such a spirit stone mine, even a pig could break through.”
"Indeed."
Nodding her head, Qing 'Er could not help but laugh."According to the analysis of the humans, this should be a medium-sized spirit stone mine that should be enough to meet Master's needs.”
"A medium-sized spirit stone mine?"
Smiling, Yu Zi Yu was also rather excited.
With these spirit stones,
His breakthrough was about to begin.
Thinking up to here, Yu Zi Yu also exhaled deeply.
The tree roots immediately wrapped around him, and in the blink of an eye, a few large nets were pulled out.
"Qing `er, take these nets and ask Nine-Tails and the others to bring back more spirit stones. Try to fill up this square.”
Speaking up to here, Yu Zi Yu seemed to have thought of something and added,""I'll use the roots to open up a few more small squares. When the time comes, let Nine-tails and Devilox choose one each and use the spirit stones to cultivate.”
"I thank Master on their behalf.”
Pursing her lips into a smile, Qing 'Er waved her sleeves and rolled up several large nets. She led Nine-Tails and the others towards the spirit stone mine again.
However, after opening up the tunnel, their speed was obviously faster than before.
The Wind Wolf and Nine-Tails were especially fast. In just a short while, they had already returned with a large pile of spirit stones in their mouths.
Seeing this, Yu Zi Yu also smiled and used the tree roots to arrange the spirit stones.
However, what was slightly unfortunate was that these spirit stones had not been cut and were all some oddly shaped ores. Even if Yu Zi Yu had the intention to place them, it looked like a messy pile of small mountains.
Shaking his head, Yu Zi Yu did not mind.
Compared to this, he could already feel a very dense spiritual energy wrapping around his roots.
"Hu, hu…"
As if they were breathing, countless tree roots expanded and contracted.
At the same time, Yu Zi Yu also controlled the black tree roots that were like black pythons, surrounding the entire spirit stone hill, pulling it into a small circle.
"It's almost time to advance."
Yu Zi Yu silently recited in her heart and also sank into her main body.
Boom! A loud sound like a bolt of lightning struck his mind.
Immediately following that, Yu Zi Yu's entire person trembled for it.
It was ethereal like a galaxy, and the world was colorful…
Under the night sky, the entire world was colorful.
And that, even if the Extraordinary Era arrived, the source of power was spiritual energy.
Only, at this time, with the spirit stone mine, Yu Zi Yu did not draw in this spiritual energy on a large scale. Instead, it was the roots hidden deep in the ground that swept up.。
Boom!
As if it was swallowing and spitting, the spirit stones placed in the underground square shook at the same time.
Immediately after, countless wisps of spiritual energy surged out of the spirit stone like ribbons. Before they could even take a step in the air, they had already swarmed toward the spirit stone along with a suction force.
In the blink of an eye, the entire underground square was in a small storm.
