"Now let me tell you the real reason you and your loved one have been hearing all those strange sounds!"
Lin Tian smiled slightly and continued, "This plant, named Blood-colored Spirit, is a special medicinal herb that contains a faint neurotoxin. Once the flowers bloom, they continuously release a fragrance from their pistils, and this fragrance is poisonous!"
"Of course, since the toxicity is mild, briefly smelling it won't cause any discomfort. However, if you smell it for a prolonged period, such as an hour or two, the toxins will accumulate in the body and cause abnormalities in the auditory nerves, leading to auditory hallucinations!"
"Mrs. Feng, you and your husband rest in this bedroom every night, inhaling the fragrance of the Blood-colored Spirit, thus experiencing hallucinations under the influence of the toxin."
