The book seemed to have been leafed through often. It was stained with blood, its cover curled, and even the lettering had faded, leaving it barely readable.
Yang Yi took it and obtained its item information.
[Name: Limb Grafting Notes] [Type: Treasure] [Quality: Fine] [Description: An introductory text of the Limb Spider Cult, and essential reading for grafting doctors. Reading it will reduce sanity (0-20), with a chance of learning Grafting Surgery, which requires a Grafting Kit to perform. Access to opportunities for practice or a teacher will further increase the chance of learning successfully. Allows other limbs to be surgically attached to the human body. The success rate is highest at joints, followed by bones, and lowest at the abdomen. For highly skilled practitioners, the success rate will increase significantly.]
"You read this book?" Yang Yi asked Su Na.
"I skimmed through it once." Su Na nodded in acknowledgment.
"The Grafting Surgery described in here causes severe rejection, inflicting tremendous pain on the patient.
"If you're going to graft something, it's best to use the Spider Queen's spinal fluid alongside it. That can greatly reduce rejection.
"Or you could use that miraculous spell you know."
Su Na rattled off a whole string of words, placing heavy emphasis on "miraculous spell," wanting Yang Yi to reveal something.
But he acted as though he hadn't heard her. He glanced at Su Na's sanity and found it was 79/80, down by only one point.
It seemed this book hadn't cost Su Na much sanity.
Instead, he asked her, "You learned this surgery?"
"More or less, but I can do better than what's in the book."
Su Na seemed rather dissatisfied with the book.
Yang Yi flipped through a few pages, giving it a cursory look as well.
