In Konoha: I Am the Old Demon of Black Mountain

A soul from Earth collides with the remnant soul of a powerful cultivator from another world. Luckily, he activates a System and destroys the expert's spirit.

Huh? Why did the expert leave behind memories, cultivation techniques, and a puppet general? And why have I awakened spiritual awareness, too?

Now that I've awakened spiritual awareness, what am I supposed to do about Black Zetsu underground?

What? The puppet general was captured by the Akatsuki, and they want to control him with the Sharingan? Uh, are they sure they're not inviting trouble in?

My soul reincarnates in Konoha. What the heck? My mom is Kurenai Yuhi?

Staring at the young woman before him, who had given birth before getting married, Yuhi Shinyun fell into deep thought. Should he call her Mom or not?
