With the System, I Am Killing Everyone in the New World

She was once an ordinary social creature in the real world, but after her accidental death, she was selected by a mysterious high-dimensional system and traveled to a different world where magic and swordsmanship were intertwined. System prompt: "Ding! Congratulations to the host for binding the 'High-Dimensional Life Simulator'. This system will help you reach the top in the new world!" She: "Wait! This familiar routine... Am I going to become a Mary Sue heroine?!" System: "Host, please rest assured that this system is by no means mundane. You will gain a high-dimensional perspective, be able to see into the nature of all things, deduce future trends, and even... Rewrite the rules of the world!" Her: "It sounds powerful, but I refuse! I just want to lie down!" System: "Sorry, the host has been bound and cannot be released. Warm reminder: Negativity will trigger the punishment mechanism, including but not limited to: becoming ugly, bald, and turning into a frog..." Her: "..." In this way, she was forced to embark on a journey of "killing everyone" in the New World. With the blessing of the high-dimensional system, she could see through her opponent's weaknesses at a glance, easily solve ancient puzzles, and even... Seduce the cold and ascetic Elf King? Elf King: "Woman, you successfully caught my attention." Her: "No, I'm not, I'm just completing the task!" System: "Ding! Congratulations to the host for completing the hidden mission of 'capturing the heart of the Elf King'. The reward: the secret treasure of the elves - the seeds of the Tree of Life!" Her: "..." This is an anti-conventional adventure story from another world. The heroine has a high-dimensional system, but she just wants to lie down. However, the gears of fate have already turned. How will she live in this new world full of magic and conspiracy?
