Island Survival: The Heroine Is a Total Try-Hard

[Transmigration to another world + no male lead + System + sci-fi + survival on a deserted island] Chi Jing was inexplicably pulled into a deserted-island survival game. From the start, she had nothing but a thatched hut, and the System offered nothing but a seven-day beginner protection period. After finally obtaining a divine artifact, she got it eaten by a shark? At first, Chi Jing thought it was just a game, so she dutifully focused on surviving. But the longer she survived, the more puzzled she became. Was this game virtual, or was it another world? Was the System actually a group of people? What had brought her into this game in the first place? She could only uncover the truth step by step, all on her own. Note: No romantic pairing. The heroine grows throughout the story and has no powerful golden finger. This is not a wish-fulfillment story, so please steer clear if that’s not for you.
