Seven Layers of Hell
After 200 years of living in their own bubble, humanity was finally dragged back to Yamani due to their own negligence. Without their knowing, they are returned to the order of life of their ancestors. Humans are back to being slaves who can be enjoyed by all kinds of creatures. One year later, they realized that they were a small part of the humans who lived in that layer of soil, while the rest were still living safely on Earth. The announcement from the Queen awakens the fighting spirit of the old soldiers who want to return to their sins and save humanity. Without being able to realize that all of that is part of the great destruction that will come to them. The battle within the seven layers of hell has finally begun.
The Little Hint
"We burned it."
Langit nodded in response to that. "And it's not easy, is it?" he guessed, justified by a member of Wisnu's group.
They know that creatures that look like them and like to eat humans have strength that is many times greater than that of ordinary humans. Hunters like them were quite able to match the strength of the wrenas because they were used to dealing with many wild beasts, some of the animals in the forest were even much bigger than their bodies.
It took two to three hunters to defeat a wrena and make them die before they managed to burn it. No one wants to let these terrible demons live, because the last time a guard freed the demon, his village was destroyed because the wrena was able to heal his wounds very quickly.
