In an experimental accident, top quantum physicist Lin Wei carried a "civilization observer" implanted in her left eye and traveled back to the era of primitive tribes before writing existed. As the "god-given trophy" of the leader of the cannibal tribe, she must use modern knowledge to survive in the Stone Age, while using a scientific perspective to examine the evolution of primitive civilization. When the observer showed abnormal interference in the civilization process of this time and space, she discovered that her journey through time was no accident - another force was deliberately distorting the early process of human civilization. Lin Wei had to choose between remaining neutral as an observer and intervening. Every decision she made would affect the direction of the entire human civilization.
