Time passed, second by second.
After about one Shichen, Su Chen had moved as many rocks as a whole mountain…
Finally, that pile of rocks was completely cleared away.
A deep sea cave appeared!!!
A very strange cave.
The entrance wasn't large, but there seemed to be a layer of deep blue, translucent halo rippling there. It was a Formation, some ancient Formation…
This ancient Formation actually resisted that terrifying deep-sea pressure, actually resisted the impact of the boundless sea water.
It had existed for a full Ten Thousand Years upon Ten Thousand Years, yet it hadn't cracked.
Even stranger, from within the cave, separated by the Formation's halo, waves of rhythmic pulsing sounds were rolling out.
The sound was very faint, like an illusion.
But Su Chen heard it. Not only did he hear it, his heartbeat actually completely resonated with it, echoing along with it…
