The Little Cannon Fodder's Sister Changes Her Fate

I set up a system, but in the end, I couldn't help with anything. I only knew the plot (you can know it through the book, which is redundant), what elixirs and treasures can't be given to the host, and I don't even know where the treasures are. I can only explain the effects of the elixirs and spirit beasts. What's the use of a system when you have a portable grandpa? Set up a portable grandpa who cannot help the heroine when she is in danger. The heroine does not understand elixirs and spirit beasts and will not explain them. What's the use of carrying grandpa with you? The two might as well become one. The heroine's sister is indeed small, but the original text is not stupid. Very strong character. As a result, the author describes the relationship between the heroine and her sister. He really looked like a child. But readers are not children. Can't appreciate it.

Very well written. Engaging, not cliche, and well organized. My elder sister is so kind to my younger sister, just like my mother. I hope my sister won't be a white-eyed wolf. In the original book, it was my sister who killed her sister.

Is there a male protagonist 🧐
