Pika Sage listened to Angel's account, pondered for a moment, and said, "The foundation of the Deceitful Smile Shell is the Recording Shell invented by the Pi Luoxiu clan. The Recording Shell can record all the audio present in the Mirror Ghost's laughter, and only through manual adjustment by Pi Luoxiu scholars can the effect of the Deceitful Smile Shell be achieved."
"What you mentioned, sir, is actually having the subjects accept images. This is different from accepting sound frequencies."
"However, having subjects accept sound or images is essentially a deception of the sensory organs. In theory, it can be achieved."
Pika Sage spoke rapidly and immediately added a clause.
"But, this is only theoretical. The Recording Shell was invented after years of painstaking effort by several Pi Luoxiu scholars, and the amount of inspiration, time, and technical resources invested is difficult to explain in just a few words."
