He won't turn into a human later
Detective Lin Chen died in the line of duty and woke up as a Chinese pastoral dog, commonly known as a native dog.
As soon as he accepted the reality, a criminal investigation system popped up in his mind: super sense of smell, clue perspective, understanding human speech, and a gift package for newbies to protect his body.
There was a murder in the village, and everyone said it was an accident. He took out a cyanide water cup and a woman's hair, leading the veteran policeman to overturn the conclusion, and the real murderer was arrested.
From then on, the local dog cheated all the way. Ten years of unsolved cases, serial killers, inter-provincial trafficking gangs - cases that the police couldn't solve, he locked up in three minutes.
No characters are changed throughout the whole process, no abuse of the master, no punishment, just a fun story about solving crimes.
His name is Achen. A Chinese pastoral dog that scares criminals.
