[Time travel + ancient novels + house fighting and palace fighting + overhead + big heroine, weak emotional drama] Yan Ying was originally a cultural relic restorer who was admitted to the establishment.

However, the gears in her destiny are tightly interlocked one by one, and she cannot completely move them by herself. People she trusts often die tragically, and the backlash is approaching her step by step...
