The wicked female cannon fodder has arrived home

Saint Mary class representative, beware!!! Transmigrating into a book + infrastructure + farming + online shopping mall system + doing business + no CP + daily food + fighting for the best!!! A brainless and slow-paced cool story, don't read with your brain, the heroine goes crazy every day and is immoral at any time! The heroine is: a turtle eats a turtle, and doesn't recognize her relatives! The main theme is that a woman without morality is wealth! What does the cannon fodder want? Immorality, sudden wealth and freedom...
