While Chen Yu was taking a breather, one of his viewers sent multiple paid comments.

The placebo effect was also known as the psychological consolation effect.
It was a common method of psychological treatment used to help patients with severe illnesses with low tolerance to drugs.
Through hypnosis, suggestion, and dialogue, placebo could help patients reduce their psychological barriers, increase their confidence in overcoming their illness, and achieve a better effect in their overall treatment.
Not only could a placebo drug treat mental illnesses, but it also had a significant effect on physical illnesses.
The folk witches and shamans, as well as charlatans, often used this method to confuse others.
