Her Family Really Does Own a Mine

Song Jinqing was reborn on Xuanjing Continent in the interstellar era. Armed with an ancient martial arts manual, a natural talent for wind-based abilities, and a gift for identifying gemstones, she was determined to become the greatest gemstone appraiser in the galaxy. But after finally leaving the "newbie village" where she'd spent the first sixteen years of her life, she discovered four words stamped on her forehead: Female Side Character No. 3.

Looking closer, she spotted tiny words between the strokes: Plot Trigger Countdown: 10, 9, 8...

Huh? Wait...

Once she realized she was just a character in a book, all Song Jinqing wanted was to stay far, far away from the male lead and live a quiet, peaceful life...

But this world is running out of energy, its plants and animals are mutating, and radiation is almost everywhere... Huh? How did she end up as the knight of all the female side characters and the beloved darling of the villain group?!

The outside world is so scary. She really wants to crawl back underground!

But Granny says she isn't allowed home unless she gets into college!
