This was an advanced microscope of such exaggerated precision in its mechanical construction.　　Over the course of a day and night beneath this microscope, within the microscopic world of the dissected white mouse cells, Grimm glimpsed a mysterious region he had never encountered, never heard of, and never even imagined. Moreover, this enigmatic zone appeared to exist within every living cell.　　This enigmatic zone was exceedingly minute.
