Transformation: Junior Sister, Don't Be Afraid, Senior Sister, I Have Become an Immortal

This is the system of my dreams. It does not abuse the owner, does not obliterate, and the tasks are negotiable and not mandatory. The author can also write about the protagonist and his junior sister's childhood, and the protagonist and the daughter of the city lord's palace. There are still some questions 1. Is it a single heroine or multiple heroines? 2. Is the protagonist invincible? Authors need to know how to interact more. This reader has fallen in love with your cover, so you understand, right?

It's very beautiful, but there's just too little. I don't know if I'll be able to finish it in my lifetime.

Big cheers for the author! Also, don't have too many female leads, otherwise I'll have to pay you in installments [laughing evilly]

It looks good, but there are very few. Come on, the author [sending my heart][sending my heart]
