A brain tumor surgery took away Lin Wan's proud learning ability, turning her from the pride of the medical school to a "craniotomy failure" ridiculed by everyone.
Until an anatomy class, the moment her fingertips touched the body, her sleeping ability suddenly awakened. The surgical scar became her "third eye", and all the diseases in the world were invisible to her - the professor's hidden heart disease and the source of her classmates' genetic diseases, all turned into a beautiful and deadly energy map.
When her former mocker knelt down to survive, and when she relied on this ability to easily seize wealth and awe, Lin Wan saw the ultimate horror deep in her brain:
That surgery never actually "removed" the tumor. A strange, translucent symbiotic body was tightly entwined with her nerves and blood vessels, slowly squirming in her skull with a breathing-like rhythm.
She glimpsed the disease of all living beings, but she didn't know that she had already become a breeding ground for the selection of non-human species.
