Beneath the Dayin River, inside a cave.
The stone door, about three stories tall and less than two stories wide, was embedded askew in the rock wall.
At first glance, it looked like a mirage.
Yet the edges of the stone door were cracked with numerous fissures in the rock.
It was as if a tremendous force had smashed the entire stone door against the rock wall, embedding it within.
This stone door, straddling the line between illusion and reality, was also where a great number of ghostly fireflies emerged from the cracks.
Flowing along the current, they polluted the Dayin River that stretched for thousands of miles.
"Is this the source of the Dayin River's transformation?"
Lin Yan's gaze suddenly grew solemn.
And these hundred-odd corpses turned soldiers arrived in front of the stone door.
The copious ghostly fireflies continuously clung to their bodies.
After a moment, the one at the forefront, "Pei Xiong," reached out his palm before the mirage of the stone door.
