One day hundreds of years ago, Su Nianhe lost forever the only sister who was good to her.
When she witnessed her sister being killed, the violent blood in her body could no longer be controlled. Her original black hair instantly turned to white, and her eyes changed from brown to blood red.
In the end, she dyed half of the sky of Linglu Mountain red with the blood of those who attacked Linglu Mountain.
Later she knelt before her sister's grave and told her that I had found a way to resurrect you.
The price is to use blood as a sacrifice, tattoo the bloody shore on the back, and lose emotions to become a tool of killing.
Su Jinhe lost his memory after his resurrection.
Later, the two met during a hunting mission. After experiencing various encounters, Su Jinhe recovered his memory. He also regained the lost feelings of his sister.
