Since Loose Cultivators rarely used Runes, Mo Hua had never even seen a Rune with his own eyes up until now, so he had cast that question to the back of his mind.
Now that they were discussing Artifact Refining and he heard mention of Rune making, Mo Hua suddenly remembered and decided to ask.
Master Chen tugged at his beard, furrowing his brow in thought, "I am neither a Formation Master nor a Talisman Master, so I can't say for certain, but since you asked, I'll tell you what I know."
After finishing, Master Chen added, "But these are certainly words from an outsider's view, just listen to get an idea, and don't necessarily take them as truth."
"Mhm, mhm," Mo Hua nodded repeatedly.
"To my knowledge, Rune making is both a branch of Formation and a branch of Artifact Refining."
"A hybrid of Formation and Artifact Refining?" Mo Hua exclaimed in surprise.
