One by one, reaching his goals

Seven hours after Yanchan left Mark's control and left in search of his sister.

Mark looked at the evening sky, already darkening, from the top of a mountain. Yuri was beside him, looking up at the same sky while looking at a small tree with wide and curious eyes. 

He was now clean.

With a deep gaze, Mark stared at his palm, thoughtful.

Now that the Savage Lord is dead, the demons could—in theory—conquer this world slowly. Since I also weakened the savages so profoundly, I guess new mega-dungeons would be appearing here in a month or two. 

He had caused yet another world's destruction. It might not have happened yet, but it wasn't far from happening; he had already planted the seeds. Mark wondered what he felt about this, while at the same time, turning on his system to see his new Ultimate Demonic Arts.
