After spending his hunter points to get the book, he only had 23 hunter points left. He went back to the Bronze hall to pick on hunting quests. He was not planning to focus on hunting, but since the quests did not have a time limit. He could just apply for it and work on it while he was doing other things.
He asked Peniel what monsters were common and easy to encounter for levels ranging around 15 to 20. Peniel advised him to retake the hunting quests for Silver Wolf, Goblins, Grey Sabrecat, Gremlins, Gnomes, and Lizardmen since Jack didn't plan to go anywhere far. They were the most common monsters around this region.
She then told Jack of some higher-level monsters that were also easy to encounter, but they roamed a bit further from the capital. It was Green Harpy, Bald Eagle, Fire Jackal, and Giant Worm. Jack followed Peniel's instructions without any question and applied for the quests.
