Mary Sue Is the Cross-Dressing Stepmother's White Moonlight

Lian Ying had always thought she lived in an ordinary modern society, until one day a Demon King dropped from the sky and burst into tears in front of her. "My daughter! My precious baby girl!" Lian Ying: ? After learning who she was, Lian Ying was taken to the Abyss by His Majesty the Demon King. They arrived that day, and the Demon King kicked the bucket that very day. In the Abyss, purebloods ruled. As the Demon King's biological daughter, Lian Ying was born a powerful, top-tier pureblood. Even though the Demon King had an adopted son, the throne still passed to Lian Ying. Forced to become the Demon King, Lian Ying had to watch out for her elder brother, who kept plotting assassinations, and stay wary of her father's wife, her stepmother.

Her elder brother stopped picking fights every day and instead spent all his time lurking around the palace, watching her until she felt uneasy. Elder brother: Stare Lian Ying: Why are you all still awake so late every night? And then there was the subordinate she had always been so proud of. He had helped her with government affairs, and now he had followed her into the harem. Her subordinate was utterly sincere as he strongly recommended a consort-selection event for the Demon King. "Your Majesty works so hard every day. Why not bring in some new people..." Lian Ying opened the list, and the very first name on it was her subordinate's. Lian Ying: ...I want to burn this.
