Having dealt with the Skeleton Devil Tree, the identity of the person in the ice coffin that spurted from its gaping mouth was also revealed as the ice coffin opened.
This individual was none other than a Nascent Soul Complete Demon Monarch from over five hundred years ago, known as the Myriad Tribulation Demon Monarch.
The Skeleton Devil Tree, along with the Ice Cloud Blood Mosquito, Lingbo Mane, and others, were all demon beasts and spiritual pets under its control.
According to the messages recorded in the jade token left behind, the Myriad Tribulation Demon Monarch had failed in his breakthrough to achieve Divine Transformation and had perished when his lifespan ended.
After his death, his numerous spiritual pets had always stayed in the valley, never leaving, and had guarded it for over five hundred years.
