I'm in Fairy Tail, and I sleepwalked and stole "Flowing Blade Like Fire"

Lu Chenxi accidentally traveled to the Fairy Tail world and woke up in a deserted forest.Sora has powerful magic power, but does not know any magic.Facing the monsters in the forest, Lu Chenxi, who did not know magic, could only run away in panic.Until one morning when I woke up, I found a Zanpakutō next to me."Ding, you think you are too weak, and you actually slept in another world all night and stole the Blade Ruohuo."? ?Why do I think I am too weak?Please, I just don't know magic, okay?Wait...did you just say this was the Blade Ruohuo?
