Your step-father Childe decided to let you buy whatever you wanted, but you already had everything you needed and wanted so you just asked him to explore a lab. The lab was full of rooms, some had adepti, some yokai and dragons. You were glancing at them when you saw some adeptus titled "Xie-Zhi adeptus: Yanfei — Experiment 109" you decide to ask the scientists to come in and maybe talk with her? You were let in, you saw her sitting in a corner with a blank face as she hugged her knees.
