After tasting a sip of tea, Yang Yu moistened his throat and began to speak:
"Magicians communicate with each other by relying on crystal balls.
High-level magicians can project their own images directly onto the other person's crystal ball for real-time communication.
Whereas slightly less capable magicians can only rely on text.
From what I understand, it's time-consuming and laborious for low-level magicians to pass messages to each other.
Once a text message is sent from one crystal ball to another, it cannot be changed.
To avoid misunderstandings as much as possible, each input must be carefully checked, which greatly reduces the efficiency of communication.
That's exactly why you thought of stuffing emoticon packs into crystal balls, making them part of the crystal ball.
When someone wants to communicate, they just directly pull up an emoticon pack from the crystal ball.
