The End Is Coming: I Only Have Thirty Days Left to Live in the Beginning

At the end of summer, they traveled through time together again, and as soon as they opened their eyes, they were pulled into the dungeon by the system. The start of the dungeon is in hell mode. The whole world is polluted by Yin Qi, and she needs to find human food. She was delicate and frail, but before she could find any edible plants, she was chased away by a seventh-level giant python. Fortunately she is smart and witty... Fortunately she has a lot of charms... Fortunately, her storage bag is still there... If you can't beat her, grind slowly. This copy is not bad. You can drop treasures when you fight monsters. The crystal core of this giant python can actually help her practice black power. Come on, crystal cores, put them all in my sister's pocket! It's just that... She only has thirty days left to live, so she needs to earn merit? This new world she wore turned out to be another apocalypse, a wasteland world that would be polluted by Yin Qi... It would be difficult for an orphan girl like her to get along if she was too weak. She must improve her profound strength as soon as possible!
