Qing Transmigration: The Most Dazzling Pearl

After transmigrating here due to a disturbance in the space-time continuum, Qing Huan needs to absorb dragon energy to restore her energy. She discovers that she has transmigrated into the world of Empresses in the Palace, but things aren't quite the same as in the original series... (This isn't a story that vilifies anyone. I'll do my best to keep everyone in character. The heroine didn't come here for a palace intrigue mission, so this transmigration-and-palace-struggle story is a little different from the others.)
