After Chen Xin awakened to the ability to communicate with animals, he embarked on the path of metaphysics to solve crimes. She relied on a rat informant to solve the first case of a brainless female corpse. She was hired as a consultant to the Federal Ministry of Security, but was initially despised by the agents. Later, he used cockroaches to explore secret rooms and stray cats to provide clues to solve the serial murder case, which convinced everyone. Rats, insects, cats, dogs, and birds formed a huge intelligence network. She was recruited by the General Administration and promoted to the chief consultant of the Special Talent Program. The international espionage circle was afraid of this oriental woman who could use the creatures in the city to detect everything. She repeatedly solved serious cases with her animal informant network and became the king of mysterious informants.
