Animal behavior researcher Shen Tinglan accidentally comes to the Ten Thousand Demons Spiritual Continent, binding the All-Spirits Beast Perception System, and is able to read the inner thoughts of various divine beasts. Facing the divine beasts of different races in this world and heaven, she does not rely on high-powered demon power, but with solid observation experience, cracks various difficult problems such as cubs refusing to eat and abnormal behaviors. She travels everywhere, visits multiple demon clan territories, records the living habits of different living creatures, and resolves dilemma after dilemma brought about by the environment and behavior. Along the way, she supports each other with the suanni Jinchuan, gains the trust of numerous divine beasts, establishes the All-Spirits Observation and Conduct Institute, explores the unique survival mysteries of the living creatures in this different world, and opens a new journey that is warm and full of wondrous encounters.
