In an instant, it reached fifty kilometers.
Countless sounds within fifty kilometers appeared in Xu Qing's divine perception at this instant.
There was the sound of water flowing, the roars of ferocious beasts, the sound of fish swaying their tails, the sound of sand moving with the undercurrents… In fact, there was even a sound that sounded like breathing coming from the Forbidden Sea itself.
It was bizarre and drawn out…
Everything appeared in Xu Qing's divine perception. He had a feeling that as long as he wanted to, all these sounds could be used by him.
Hence, at the next instant, the area of fifty kilometers around him suddenly fell silent.
All the sounds were stripped away by Xu Qing's thought and sent outside of fifty kilometers.
With the help of their sounds, the ripple continued to spread.
250 kilometers, 500 kilometers…
The cycle repeated.
