Li Jinglan stayed up all night reading The Untamed and tragically died of sudden cardiac arrest. Because she was so fixated on protecting Wei Wuxian, she accidentally found herself transported into the book.
What? Wei Wuxian's parents died, leaving him to wander alone? After Jiang Fengmian adopted him, people mocked him as the son of a servant? All the cultivation clans joined forces to attack the Burial Mounds? Not on her watch. She would step in.
With the story in her hands and as Wei Wuxian's maternal aunt, she would protect him. (The plot has been changed considerably, and the pacing is a little slow. If that's not your thing, don't read.)
