Have I Become the Ring Grandpa of the School Belle?

My name is Cheng An. I come from the Dark Ages and rose from the Age of Chaos. I have killed ancient gods and shaken the Eight Desolations. I was a terrifying existence in that era. However, I was trapped in the ring for some reasons until a soft and sinister girl came to the door. Seeing her sincere attitude, I reluctantly became her ring grandfather... —— My name is Gu Lingxi. I come from another world and live in an era where cultivation is possible. Human beings here live in one living circle after another, and the outside is a forbidden area. That day I entered the secret area of the school and a ring cried to me. He said he was very pitiful and hoped that I would take him away... But many people say that rings are useless and useless, but I found that it is not that simple... He can take me to hunt for treasures in restricted areas, as if I were visiting my own home... But the only bad thing is that he asked me to call him brother. I want to call a hundred-year-old grandfather brother... Tonic... It's really embarrassing! Cheng An: "Are you really not screaming?" Gu Lingxi: "Brother~"
