Jagged Germany - Chapter 1778: blast back to the stone age

Noah Brown had a gift for fighting. Unfortunately punching things didn't pay the bills, at least until he died and an Eldritch god found his soul. The encounter led him to a new world, summoned by bloody cultists, with nothing but the shirt on his back, and a strange item in his system menu.

[???] : A source of infinite potential.

Perhaps he'd finally get to put his gifts to good use.

A long time later, Ah Zhao and her younger generations started chatting about her own story.

“At first, I was selected by the system to become the man’s plug-in to help him reach the pinnacle of life.”

“-Then what happened afterward?”

Ah Zhao lit a cigarette and her expression had great changes:

“-Later, I became the wife of the Male God.”
