Three hours later...
For the next three hours, Aaron and his small army of undead started to clear every monster in sight. All the monsters that he faced were weak. There are various monsters, but the highest that he faced were monsters that crossed to Rank-2 recently.
Clearing them out was very easy, and it also made Aaron very happy. Though the level-up speed is not very high, he collected a lot of resources. Some of them he can use and some he can't, which can be sold for credits at the academy.
Though he gets 1,000 credits every month, his increased appetite and the requirement to enter higher rank dungeons make those 1,000 almost non-existent. There is also the need to buy books from the library to increase his knowledge.
