A terrifying nursery rhyme (5)

"The smell of formalin didn't come from behind the door. It came from the surface of the door." About ten seconds later, Ling turned on the oil lamp again (there wasn't much information on the door, so anyone could remember it after a few seconds) and said,"but ... Under normal light, we can't see the liquid on the door."

"That's not right ... Formalin doesn't have any color. " Xiao Tan added,"and not in the dark ..."

"There's nothing strange about it. " Feng bujue cut him off."This means ... The liquid on the door is not formalin."

"It can't be ... I'm familiar with this smell. It ... Can't be wrong, right?" When Xiao Tan reached the latter half of his sentence, he lost confidence.

"Because you have more experience in formalin, when you smell a similar pungent smell, you subconsciously bring this experience into your mind and come to the wrong conclusion." As Feng bujue said that, he walked to the door to take a closer look.
