What was the flute sound?
Gu Xijiu looked at the big mussel. Why didn't she hear any flute sounds?
Suddenly she thought of something!
She had the modern knowledge and knew there were some sounds that were inaudible to humans in this world because human ears had its limitations when receiving some high-frequency sounds. However, this high-frequency sound could be heard by animals. For example, the movement before an earthquake could be heard by birds, so they would feel insecure even before the earthquake, but alas, humans were not able to pick up this sound...
Would it be the case when the big mussel said it heard the flute sound?
Would it be the culprit behind this who is actually playing some kind of special flute that could not be heard by a human to control the venomous person?
As the venomous person would have spells inside their body, they would be under the control of the culprit.
