"Who... who exactly are you?"
Lei Ayoudo, having seen that Chen Feng was completely unaffected by her Gu Worms, had already become panicked. She looked at him as if she saw something terrifying. She remembered a sentence her grandfather told her when she was a child, "If one day you come across someone who is not controlled by your Gu worms, do not oppose him, because that person is very likely to be from the Innate Realm."
But Chen Feng was still so young, Lei Ayoudo found it hard to believe he was a master of the Innate Realm. She suspected he had some other trick that made him immune to Gu Techniques. She was both panicking and doubting.
