"All right."
"I believe everyone now has the concept of 'why' in mind."
"So let's talk about the specifics."
Seeing that her question had achieved the result she wanted, Lan Qingyou gave an almost imperceptible nod.
Then she waved her hand.
The purple Alchemy Array that had been there was "tossed" into the air.
As it rose, the Alchemy Array continued to expand.
In the end, it enveloped the entire classroom.
"The patterns on an Alchemy Array are actually very simple: triangles, circles, squares, and connections between Magic Circuits."
"But even these simple patterns can greatly enhance the effects of potions."
"So first, let's talk about the triangle, which is used most often."
"Everyone knows that triangles hold a special place in Semiotics."
"When the point faces up, which is commonly known in alchemy as the 'upright position,' it represents the element of 'fire' among the four great elements."
"Likewise, when the point faces up, adding a horizontal line through the middle represents the element of 'air.'"
"When the point faces down, forming an 'inverted triangle,' it represents the element of 'water.'"
"Likewise, an inverted triangle with a horizontal line through the middle represents the element of 'earth.'"
"These are the four great elements that make up the world."
"Besides these, adding certain things to a circle can represent all kinds of mineral elements."
"For example, an empty circle represents 'oxygen.'"
"A dot in the middle represents 'hydrogen.'"
"A vertical line connecting the top and bottom represents 'nitrogen.'"
"Adding a cross represents 'sulfur.'"
"These are concepts from Drafting and Semiotics, but they're just as significant in alchemy."
"So in alchemy—especially in potion brewing, which most of you alchemists are familiar with—subjects like Semiotics, Magic Array Studies, and Drafting are unavoidable."
"Now, let's return to the question from earlier."
"Why can
