However, after Nie Jiuque's death, Zuo Yan took advantage of the barrier's weakening to transform this place into a dungeon, setting numerous traps.
The king of the beasts here became the Guardian of Zuo Yan's dungeon.
Yet those imprisoned here are not those guilty of heinous crimes, but rather those who oppose Zuo Yan, most of whom belong to the Demon Clan.
Many were once Nie Jiuque's loyal subordinates.
Those who defied him, refused to collude with him, plotted to seize power, threatened him, or simply those among his own kind he disliked, were all heartlessly confined here to suffer endless torment, never to see daylight.
Amidst the rolling quicksand, a black figure gradually emerged, the newcomer seemed injured, stumbling somewhat awkwardly.
It was Zuo Yan, tormented under Nie Jiuque's hand.
At the dungeon's entrance lay a massive beast, sensing someone approach, the beast opened its eyes, saw it was Zuo Yan, then lazily closed its eyes and slept.
