Nian Shilan Reborn: The Yiguan Chronicle

After Nian Shilan died by smashing her head against a pillar, she was reborn on the night before entering Prince Yong's manor. Carrying seventeen years of memories and a body covered in wounds, she wanted to change her fate, only to discover that changing it was harder than dying. The greatest danger wasn't the emperor or the empress. It was her own nature.
