Xu Nian'an, an innocent young man who grew up in a Taoist temple in the mountains, was forced to go down the mountain to integrate into modern society because the Taoist temple was demolished. Unexpectedly, he was born with a "humanity experimenter" golden finger - whenever someone is malicious or kind to him, a progress bar of the corresponding color will appear above his head, green for kindness and red for maliciousness, and it can also display the other person's true thoughts in real time.
As soon as he entered the city, he met Lin Wan'er, who claimed to be his childhood sweetheart, but there was a red stripe on his head: "This fool must be easy to trick, let's first let him sign a ten-year contract with food and accommodation included." The simple Xu Nian'an smiled and signed it, because he saw a line of small words under the red stripe: "Actually, I want to protect him, there are too many bad people in the city."
From then on, Xu Nianan started an interesting "humanity experiment" in the city. He used the purest way to heal everyone around him who was mentally wounded, but he didn't know that he was unraveling a secret that had been hidden for twenty years - the demolition of the Taoist temple that year was inextricably linked to the disappearance of his parents.
This is the story of an innocent boy's well-intentioned "experiment" that warmed the whole city. Funny healing, there are also laughter and tears.
