Lord of War
The next day.
Inside Eren's potion lab. Underground facility. White Raven guild's headquarters.
Eren had gotten refreshed after completing the nightly mana circuits training and sparring sessions with Alephee that followed afterward. He was now looking at a giant array that had been created by Alephee in an empty hall space.
Alephee entered the array eye and began her operations. There were various sections inside the array that were created by the intersection of complex runic details. Some sections contained metallic ores while the other sections contained various weapon artifacts.
The various chunks of various metals found in various sections of the array were obtained inside Minerva's Utopia. There were some metallic chunks that Eren had personally bought from external sources upon Alephee's suggestion.
