Lin Fan pulled up a screen in front of him and placed it between him and Rokuko.
This was the screen for his Dungeon Master System.
Since Rokuko was the dungeon core that he was contracted to, she was naturally able to see this screen as well.
The screen wasn't on the management page, but rather it was on a special page.
This was the dungeon improvement page.
Other than increasing in grades, there were other ways to dungeon cores to improve themselves. They would spend DP to unlock new features that they could access, which was the page that Lin Fan currently had open.
After a few months of saving up and more and more people coming to the town, providing them with more DP, they were finally able to afford some dungeon improvements.
