Master, You're Not Respectable

Snow Qilin asked the help of the immortal Qi Guiyuan to save her niece: in exchange he had to protect Qi Guyan’s granddaughter, Qi QiQi, in a parallel world where she was the head of the Heavenly Jade Palace sect. For doing so he learned some martial art techniques form the immortal, and he arrived to this new world, but due to the absorption of energy of thus new world, his body transformed into a very cute and very young lolita girl: he became a ten years old girl body.
After this, when he exited the forbidden sword tomb of the Jade Palace sect, “she” was renown as the little ancestor, or the young grandmaster: the sect was in a state of some internal and external strife, due to lack of power and strenght, and so “she” could only act and cope with the actual situation: “her” new martial training was so not developed but it was good enough to change the subtle balance between this and other sects. Moreover, did she have a chance to return to his previous male state and return to Earth to see his niece?
