During a casual chat, Ronin asked Lurans if there were any more advanced Magic Books in the castle, but the answer was no.
Left with no choice, he could only try his luck at the Magic Energy Chamber of Commerce. He reluctantly spent Six Hundred Gold Coins to purchase the Magic Book for *Wall of Sighs*.
This was a Guardian Magic that, when cast, could summon a massive, translucent Wind Wall to block area-of-effect attacks.
For the next two days, he studied the Magic while taking Erin around, letting the child who had lived in the deep mountains for over a decade see the outside world.
While out with Erin on Wushan Lake, Ronin successfully mastered the Magic.
Gazing at the massive, translucent Wind Wall before him—ten meters long and five meters high—he could sense its strength. It could probably even block Ridder's Blast Flame Slash.
