"Wilderness", this hacker, appeared in front of the whole world without warning. This name represents a combination, and the center of this combination - "the most beautiful mandala tree on Flevin Street", Keener. No one knows where he came to the United States, no one knows his background. He seems to be a fog of revenge, and his enemy - NYUE, is even more powerful. Can Keener take revenge? After returning from hell to the world, where should he go?
