Yue Qiluo's Multiverse Journey Begins with The Grave Robbers' Chronicles

Yue Qiluo was awakened from her slumber and was about to break out of her coffin, but a retirement System suddenly appeared and stopped her. After a friendly discussion, the two became partners. From then on, the heroine embarked on a journey through small worlds, learning all kinds of skills and making herself stronger.

I originally planned to write a long novel, but the first world didn't go as well as I'd hoped, so I've decided to mull things over and start a new book.
