Chapter 551: Black Sand Erupts! Sense of Belonging! (Second Update)
So this was it, this black sand storm, the Mountain and River Ruins were just fine, how could such a thing appear, and with such astonishing power.
Mountain River Academy must have gone mad, to create something like this in a place they had sealed themselves. It didn't look like they were guarding a restricted area, it seemed like they had dug themselves a hole and buried themselves in it.
Now Yang Zhen fully understood, this wasn't something created by the people of Mountain River Academy. It was an Ancient Demonic Pattern that existed before they had sealed him. It had just been suppressed by the True Essence Heavenly Vein during that time and hadn't been released.
