Yang Jian sat alone on the fifth floor, where he was now patiently flipping through various books.
There were texts on human anatomy, acupuncture meridian charts, knowledge of different body parts, and the like—some deep and technically complex, others popular and easy to understand with colored illustrations.
"Lividity is the purple discoloration that appears on the skin due to blood pooling in the capillaries and small veins under the force of gravity after the cessation of circulation..."
"In other words, lividity is just the accumulation of blood retained in the skin. If I can remove this pooled blood, the lividity in my body will disappear."
While reading these headache-inducing books, Yang Jian simplified his understanding and began experimenting.
He couldn't possibly walk around the streets forever with a dead man's body; it might be alright during the day, but at night it could scare people to death.
