Hell was a particularly difficult region for the players due to three reasons. 

First, the debuff. In hell, their stats and stamina would be reduced as long as they breathed. In areas where the hellfire river flowed and poison spread, there were many restrictions on activities such as constant damage or blindness. It was truly a land of death. 

Second, the diversity of demons and demonic creatures. Each of the 33 regions of hell had different environments. There were various types of demons and demonic creatures that inhabited them. The demons differed by individual and the demonkin by species. There were also major differences in combat styles. It was difficult to identify and prepare for each one. It was an unpredictable realm. 

Third, it was the absence of a map. The scale of hell was comparable to the human world. However, the actual size felt more than that. It was because there were so many rough places and maps didn’t exist. It was difficult to become familiar with the geography, so it felt like they were wandering in a maze or walking in an endless desert.

Yet even in such an infamous hell, Yura and Kraugel weren’t held back. It was thanks to Leraje. She was a living strategy book and GPS. She was the 10th ranked great demon in the hierarchy and knew too much about hell. She had all types of information that was hard for even a Demon Slayer to know and clearly guided Yura and Kraugel. The two of them had accumulated more than one or two achievements over the past fortnight with Leraje. 

It was natural since...
