The Yin Soul Realm, strictly speaking, is not a realm.
It is a small world isolated by the concerted efforts of the Four Hidden Kings and the Ten Kings, using the Ten Kings Command.
Here, ghastly qi looms heavily, and the entire world resembles Tianqian Valley and the Black Sand Sea.
Even more terrifying is that without the Ten Kings Command controlling the Ghost Specter, it can appear at any time and place.
Those living in the Yin Soul Realm might face death at any time and location.
Whether taking a stroll outside or sleeping at home, they might mysteriously die in the Ghost Specter.
As a result, the population here keeps dwindling.
Even the number of strong warriors is gradually decreasing.
If not for using the Tribulation Thought Treasure against the Ghost Specter below the sixth level, there would be some assurance; the entire Yin Soul Realm's population would have long been wiped out.
