Bai Ruozhu's expression was very grave. Although it was the first time she had encountered this poison, it was not the first time she had heard of it. She knew this poison was called "Cuckoo's Blood," as it was recorded in her half-scroll of the Poison Scripture.
Does this mean that this world has the most secretive half-scroll of her Poison Scripture? Or are there books similar to her half-scroll of the Poison Scripture? Or perhaps someone possesses an entire scroll of the Poison Scripture?
