Jake finished his breathing training sometime before the two-day rental period ended. he gained some benefits during this retreat as his stats grew by one point. He managed to get better at regulating his energy.
The third dungeon for a solo run he chose from the mission board was another unique dungeon. It was a lizardman dungeon, and the most highlighted thing about it was its rank. It was a low rank-E dungeon. Jake decided to give it a try and see how did he fare against a dungeon with E-rank monsters. He wanted to leave right away, but Alan stopped him. He was forced to rest for the next two days before being allowed to go on another expedition.
"Get enough rest and recover your mentality before running out of a dungeon. It will be dangerous for you to go on continuous expeditions." Alan was strict with his words.
