(A slow-paced story, not palace intrigue right from the start. Whether Daju gets put through the wringer depends on the author's mood.)
Xia Dongchun died, expecting her soul to return to the underworld. Instead, she continued living in the Forbidden City as a ghost. The legendary Black and White Impermanence ordered her to treat “Yizheng,” and she was saddled with a useless-consort promotion System that either never showed up when needed or issued impossibly difficult quests. Watch Xia Dongchun thrive in this low-level game. She doesn't love the Emperor; she only wants to level up, complete her quests, and land a minor post in the underworld.
