Roland studied magic in his own chamber.
Substance Transformation wasn't hard to learn. At least, the spell model that the Magic Tower provided wasn't.
But the problem was that it could only transform the four basic metals. To transform other substances, he had to figure out the different ratio of magic power.
Then there was a huge problem.
Roland didn't really know the molecular formulas of other substances.
For example, Roland knew that water was dihydrogen monoxide.
But then, what did the oxygen atom look like? How should elementary particles be combined into that? How should they be rearranged into hydrogen atoms?
After thinking about that, Roland found it rather tricky to reassemble new substances with the spell.
Having no other choice, he could only ask the netizens on the Internet in a thread.
