The water ahead is abnormally dark, with no trace of light.
Anyone who has ever dived into the sea knows that the deeper you go, the darker it becomes.
If you reach the very depths, you will feel there is no light around at all.
Being in such an environment can greatly amplify the fear in one's heart, as if hidden in the sea's darkness are terrifying giant creatures.
The fear of the deep sea gets its name from this.
At this moment, this darkness seems insignificant to Qin An and Long Tianxing.
Even with just a hint of light, the two can see the situation ahead clearly.
In front lies a vast underground cave, so deep that it's impossible to see what's inside.
"This is indeed a natural cave," Qin An performed the Nine Turns Dragon Roar Shadow Step, transforming into a blur and arriving beside the cave, gazing inside.
Qin An discovered a tiny rice grain-sized light in the darkness at the end.
If not looked at carefully, even a cultivator could easily overlook it.
