By the time they returned to the Shelter, it was already late afternoon.
After going back to the Mansion of the Berserk Gang, Aragorn separated from his 2 friends as he returned to his workshop to go check on some things.
Princess Elanor waved Rex goodbye before also going out for her own business. Left alone in the mansion, Rex went inside and after having a nice bath to freshen up, he left for the Blood Market.
After a few weeks of staying in the Gundam Shelter to settle down and thoroughly digest his gains, Rex was now ready to sell one of his loots.
After defeating one of the strongest Intermediate Mystic warriors that he ever faced, Pain, he left with the Parasitic Armor.
Since the armor was not compatible with him as a mystic warrior, Aragorn already advised him long ago to trade it when they finally get to the Gundam Shelter. The Blood Market was the perfect place for businesses like this.
