Chen Dong suffered from a disease, a disease called low-risk depression. He was educated to be unable to stop the drug since he was a child! Because once the drug was stopped, there would be two possibilities, either becoming a schizophrenic madman or an incredible genius. Unfortunately, he belonged to the latter. Since the drug was cut off, the whole world was completely overturned. If he was an expert in biology, then when he walked on the street and saw all living things, he would have an insight into the biological forms, muscle tissue, and bone tissue of the other party... If he was a doctor, then when he walked on the road, he would see the diseases of passers-by, and even the disgusting lungs of severe smokers... But he had a special liking for psychology research, and could see through all the secrets hidden in the other party's heart based on a person's eyes, body language and movements. From then on, a palace-level master of criminal psychology emerged.
