The clear river water flowed past in front of Wang Chen with a gentle gushing sound.
A faint mist hovered over the surface of the river.
The length of this underground dark river was unknown, with pitch-black sides extending over three zhang in height.
On the rock walls on both sides, there were all traces of water erosion.
It wasn't the flood season yet, so the riverbed appeared quite shallow, covered with fine sand and pebbles.
Wang Chen raised his head to look at the crack he had just descended from.
He pondered a way out of this predicament.
Wang Chen wasn't the least bit panicked because, even deep underground, relying on his Grandmaster-level mudstone technique, he could dig a tunnel back to the surface.
And it wouldn't take a long time.
He carefully observed the surroundings, pondering where to start would be the most appropriate.
At that moment, Wang Chen's gaze suddenly sharpened.
