Book Transmigration: This Cannon-Fodder Female Supporting Character Is Rather Sweet

I don't understand why the heroine is still so weak since she is given such high configuration. Is it the main strategy to open high and go low? And according to what the heroine described in the book, after the fruit was eaten by the original heroine, the heroine still felt a little bit more effective in fighting. But why do you feel that the heroine is so weak after entering the book? And that fruit that can save the heroine's life, why can't you send someone to ask the mountain master to deliver it and then go get it yourself. In the end, the heroine returned to her original form and couldn't do anything. I felt that the heroine was too weak. Anyway, the whole book was very frustrating to read. 😅
