well well now you guys would be wondering if this is tragic story of a mermaid who herself or her descendent avenged for genocide...then I am sorry to disappoint you all...this is story of a reader like you who won the lottery of fetus rebirth...applause..and the fairy tale you just read was a rough draft for my forum which I plan to use to educate my older siblings and my little freinds in an attempt to save them from being a cannon fodder so the deceiving title lol.
This should have leaked some of the major details about me in this life. So let me introduce myself my name is Samia, I go by Sam or Mia, I am a mermaid and this is 2489 AE(after established) interstellar year yes my friends I have time traveled to future and left our dear Earth long behind and I am currently 4 year old, average life expetancy of mermaids is 700 years while humans have 500 years on an average while orc live 1000 years, there are other species as well but I need to be older to do the stats to avoid being suspicious.
As a senior member of transmigation novel readers club and being completely poisoned by them for over more than a decade. I have gone through all the possible plots and how to live a millennium with peace so I have came up for some rules for myself to prevent from receiving lunch box early considering, I have no clue if it is parallel space or through a book situation, I have no system or magical space and have no idea if will have any auxiliary golden finger, to make matters worse I have no idea whether I will be a protagonist or stepping stone for one, the last one scares me a bit cause I don't want to affected by so called will of heaven. So following are the rules to save my life.
To be as low key as possible, don't be a hero and absolutely don't be a cannon fodder. Have few vests in case I want to make some waves
Learn a few lucrative life skills, come on living for few hundred years it would be boring without doing anything and maybe I can buy an agriculture planet or satellite some day..
To do good deeds remotely, they always emphasize utility of merit in almost every second time travel novel.
May be try what other travelers did like farming, cooking, carving, acting, singing, directing, driving a mecha and so on although I have no idea on how to do any of it but it would always be fun to try these..
