Mastering Symbols!

Sam, with a sense of purpose, sent Lan Yuhan a true essence sound transmission. 

This was a vital moment, and he needed to ensure every detail was conveyed accurately. 

Meticulously, he listed the required materials and precisely described how they needed to be processed. Some of these instructions were exceptionally intricate, with an attention to detail that only a master of their craft could appreciate.

Lan Yuhan, her background rich in inscription technique knowledge and memory as sharp as a razor, listened as Sam's words seemed to flow in an incomprehensible stream of consciousness. 

To others, it might have sounded like gibberish, but Lan Yuhan nodded, her eyes sharp and focused, and she replied, "Understood."

She began preparing the materials, displaying a level of skill that was truly breathtaking. Each material that passed through her capable hands transformed as if she were a magician weaving intricate spells.
