I Purify the Wasteland for My Sister's Sins

Ning Xi wakes to a chilling truth: she's a clone created for one purpose—to atone for her original's catastrophic mistake. Two centuries ago, her sister tore reality apart, scattering dimensional rifts across the Federation and plunging the world into apocalyptic chaos. Now Ning Xi must dive into corrupted pocket worlds, purifying the twisted landscapes one by one. But when an NPC calls her 'sister' and recognizes her face, the carefully constructed lies begin to crumble. What really happened 200 years ago? And is she truly just a disposable tool, or something far more dangerous?
