Brian would never have imagined that someone would dare to eavesdrop on him. His bedroom was the most guarded place in the entire mansion with several arrays and noise cancellation spells. He was a prestigious figure in his empire, hence his and his wife's safety were always his priority. He had also put the arrays on her daughters' room which in terms of power were not less than his arrays.
Nobody could enter there and had to maintain at least a 5-meter distance from their bedroom, otherwise, they would be killed instantly by the array's sharp lasers, and with noise cancellation spell he didn't bother to ask Mrs. Taylor to turn her volume down.
