"Boom!"
A tremendous sound echoed, and silver light illuminated the entire cave.
"Indeed..."
Chen Yuan, who was advancing at high speed, suddenly stopped, looking solemnly at the ancient and majestic stone door before him.
The stone door looked unremarkable, but around it countless runes were flowing continuously.
"Xuanyu Jun Mansion..."
Chen Yuan slightly raised his head, murmuring softly.
Above the stone, there were four characters carrying an endlessly vast aura.
The aura emitted by these four characters was also the original source that caused the four Beast Kings to tremble.
It was very likely that this place was the tomb of the owner of Tongshen Cliff.
Only for this reason would the four Beast Kings feel the trembling of their bloodlines.
"Should... Should we go in?"
The Thundering Sky Leopard trembled all over, its body's lightning seemed to flicker with its trembling, flashing uncertainly.
