Eren's room. Stardust guild dorm. Morning 9 AM.
Scrunch!
Eren took a bite out of a fruit that looked like an apple with some runic patterns naturally formed on it. With each bite, he could feel his fire-element mana getting stimulated in his mana circuits.
Eren had 11 more fire-element apples like these. They were called Ifrit fruits by the local populace. These fruits were a common Rank 1 resource available in Gilaahan. He had brought those fruits from Malcolm.
Eren had spent the last day practicing the new spells he had received from Malcolm. The fire-element fruits he was eating were supposed to assist him in casting fire-element spells by helping his circuits get used to converting his normalized mana into fire-element mana. The fruits also helped rankers increase their affinity for fire.
