Unknowingly, a long time had passed in this world. Du You's opening of this eight-tier world had finally stabilized, and it didn't cause much resentment among the undead creatures in this world.
Many intelligent undead became professionals and started their own professional training.
In this world, they can hunt other undead to improve themselves, and they can also improve by entering other worlds.
Perhaps because they're not afraid of death, these undead professionals improve very quickly, and they make excellent companions for many professionals. As these undead professionals gradually integrated, everyone was happy.
The upper echelons gained experience and have begun planning to fully open another eight-tier world. Of course, the specifics of when and how to do this still require preparation, and it can't be done as easily as Du You did.
The people at the lower levels were also very satisfied to have another world to enhance their power.
