Transform into a Girl and Wander in the World of Immortality

As a contemporary stinking otaku, Su Yu accidentally fell into a manure pit when he went out to buy Shenbao tablets in the middle of the night, and then disappeared. When she woke up, she had come to another parallel world. However, there was no modern technology here, only weirdos flying with swords in the sky. "Have I traveled through time?" Su Yu thought to himself. "Ding, an unsuitable host has been detected, and we are now forcibly binding it... The binding was successful! Start transforming the useless host." (Because I am a new author and my writing skills are relatively poor, I don't like to make mistakes)
