Boom~~~
In the underground space, a powerful surge of Mental Strength swept out, enveloping the entire area.
"Has... his Refining Spirit Art broken through?"
As a Ninth-Order Law Saint, Su Qingli immediately sensed what had happened. A trace of astonishment appeared on her fair, pretty face.
A Metahuman's Mental Strength originated from the Sea of Consciousness.
The Sea of Consciousness was extremely mysterious. Even Mental Type masters did not dare claim to fully understand what it truly was.
Precisely because of this, the Refining Spirit Art so closely tied to the Sea of Consciousness was especially crucial and required great caution.
She needed several hours of preparation every time she broke through in her Refining Spirit Art.
How could anyone be like Xu Jingming, flying through the sky one moment and breaking through on the spot the next?
"This guy really is a freak.
His strength was already close to mine before.
With this Refining Spirit Art breakthrough, he has probably surpassed me."
Shaking her head, Su Qingli abandoned the thought of resting.
Azure Jade Purity Divine Lightning surged forth, filling the entire underground space as she stood guard for Xu Jingming...
For ordinary Metahumans, the Sea of Consciousness resembled a starry sky, with Mental Strength as bright new stars scattered throughout it.
But Xu Jingming, who cultivated the SSS-rank Spirit Refining Art, the "Thunder Sea Meditation Technique," was different.
His Sea of Consciousness was like a vast ocean.
And what flowed within that ocean was not seawater, but boundless lightning!
When the "Thunder Sea Meditation Technique" was raised to the Sixth Level, a storm erupted above the entire thunder sea!
Rumble rumble~~
Thunder roared as wind and rain raged.
Seawater formed of 'lightning' rose into the air and swept back and forth across the surface.
The entire ocean
