Netherworld

In the netherworld where ranks were rigid, most higher ranked creatures possessed extremely large fighting strengths. However, this was not absolute. Lower ranked undead creatures had the possibility of undergoing evolution and become high ranked undead creatures as well. For example, the majority of skeleton kings that could be as strong as a bone dragon had fortuitous occurrences and were naturally produced. However, there were also skeleton kings which could have been the lowliest skeleton that underwent countless evolutions. Although the probability was extremely small, it existed. Spirits in the netherworld could swallow each other. If low ranked undead creatures were able to swallow the spirit of a formidable bone dragon, they could substantially improve a few stages. Merely, this probability was extremely low. Typically, weaker undead creatures would only instinctively escape when facing someone higher ranked than them. They would never dare to attack unless they had a master and only under their master’s orders would they disregard their lives and attack. However, even if they attacked, when facing a higher ranked undead creature, there would never be any flukes and would definitely be massacred, let alone being able to swallow the spiritual strength of a higher ranked undead creature. Most of the low ranked undead creatures that were able to evolve had coincidentally come across high ranked undead creatures that were almost killed by even stronger undead creatures. While the even stronger undead creature had not arrived, they were then able to conveniently swallow the spirit of the higher ranked undead creature. Taking the formidable bone dragon as an example, it could kill or seriously injure a group of hate warriors with one breath. The spirits of these lower ranked undead creatures were of no interest to the bone dragon. If there just happened to be a skeleton or zombie warrior in the vicinity after the bone dragon left, they would be able to conveniently devour a higher ranked hate warrior’s spirit. When such a low probability matter repeatedly happens on a low ranked undead creature, the low ranked undead creature that had swallowed the spirits of many high ranked undead creatures would be able to gradually evolve and become a high ranked undead creature that surpassed its birth restrictions.

netherworld was split into regions and territories. Some of the most ancient formidable existences occupied vast territories, ceaselessly campaigning against one another. There were even extremely formidable undead creatures that possessed the strength to tear apart the restrictions of their position, having the frightening strength to travel across the world with their own strength.
