Doomsday Descends: From the Start, I Have Just Thirty Days to Live

Xia Mo transmigrated again, and the moment she opened her eyes, the System pulled her into a dungeon. The dungeon was hell from the start. Yin energy had contaminated the entire world, and she had to find food for humans. Frail and delicate, she hadn't even found any edible plants when a seventh-rank giant serpent came after her. Luckily, she was clever and resourceful... Luckily, she had plenty of talismans... Luckily, she still had her storage pouch... If she couldn't beat it, she could wear it down. This dungeon wasn't bad: monsters dropped loot, and the giant serpent's core could actually help her cultivate mystic energy. Core, come on! Into Big Sis's pocket, all of you! But... she had only thirty days left to live. She needed to earn merit points? The world she had just transmigrated into was another apocalypse, a wasteland contaminated by yin energy... An orphan like her would have a hard time getting by if she was too weak. She had to raise her mystic energy as fast as possible!
