Plague Archfiend

Appearance
Inside the grotto, there were countless rune engraved crystal stones forming a restriction. And there were also many stone tablets with a fixed distance between them. There were more than 100 of those stone tablets around, forming a big circle. In the middle of this circle, a nearly three meters tall Ox-Headed Person was bound. Looking from far away, he somewhat resembled Horned Demon Na Gusi, but his energy fluctuation was violent, was vaguely not any inferior to Jiang Tunsheng, unexpectedly was a half-Sage realm evil spirit. He roared frequently and struggled to break free from his binding of rune chain.
