Nether River Page
Origin
An infamous cursed artifact purchased by Fu Xing from an underground market. It is a yellowed page burning with black flames.
Effects & Usage
When a cultivator uses their essence blood to write a vow of secrecy on it, a ghostly head appears. If the vow is broken, the violator suffers a mysterious calamity, as allegedly happened to the Mid Nascent Soul cultivator Feng Tianxing. It had no effect on Han Li due to an unknown object within his body repelling it.
