'I have to be faster,' Richard thought.
He considered what kind of attack he needed to unleash.
It had to destroy a wide area, but the destructive force must not be too strong, otherwise it would shatter the Spirit Nature.
After thinking for a moment, Richard decided to use his wave.
Whoosh!
His wave instantly spread out, but only as a thin layer, enveloping the entire mine.
He touched the earring on his left ear, activating its power.
It was, of course, the Echo of Wave, allowing him to launch attacks through his wave.
Through the wave, Richard sent countless lightning bolts that exploded the moment they appeared.
They appeared everywhere because they could manifest anywhere his wave existed, including the areas he couldn't reach directly.
Their explosions were not excessive, yet every lightning bolt was powerful enough to destroy one large Spirit Nature chunk.
Richard continuously released new bolts, and their explosions shook the entire mine.
