I love how MC is shocked and amazed that she would be expected to inherit her grandfather's property. Moreover, she's all like "noo I'm just a kid..." as if it's a terrible thing she wants to avoid.
How many Three Kingdoms reincarnators would be overjoyed if their powerful elders kicked the bucket and left them a bunch of money and men? Of course, it would be hard for an 8 year old to actually meaningfully control the legacy left behind by Dong Zhuo, but that's not a reason to give up on such a golden opportunity.
