Du You hurriedly left here because there were many things to attend to recently.
The most important thing was that after a period of enhancement, Du You was preparing to start clearing the territories around the surface.
Although the subterranean space didn't have a large population, there were far more Magical Beasts here. Although there weren't many cities nearby, Du You could find quite a few powerful Magical Beasts in them.
After hunting some eighth-tier Magical Beasts and turning them into Undead Creatures, the foundation of his Undead Army was established.
Du You could also see how harsh the environment here was; he now had nearly fifty eighth-tier Undead Creatures. This number likely exceeded the combined strength of the nearby cities on the surface.
