Note: this is just a fanfiction of many animes and manga, the originals didn't belong to me. I don't own anything except oc. And also my native isn't English, there will be some grammar problems but I will try my best to reduce them. and cover pic is also not mine, I take it from google, which is from solo levelling. if the honourable creator wants me to remove it, I will do it gladly. The first chapters will be short, but later will be lengthened. warning: this is written by an amateur. so those, who were searching for god-level-fanfictions, might lower their expectations. thank you.
