Battle of Selangrad (1)
In another part of Selangrad, not that far from the Inner Layer of the Selangrad.
Around ten Gold-Tier demon Professionals were tearing through the defenses of the Human Brotherhood, killing every foolish soldier that was idiotic enough to step in their path. Initially, there were more of them, but some of them needed to stay behind to entertain the Gold-Tier Professionals of the Human Brotherhood who were attempting to stop them from entering the inner layer of the Selangrad.

It was built by the architects and engineers of the Avalon Kingdom and was designed with both defenses and practicability in mind. Overall, it was very well-designed and divided into four layers for the purposes of defense and utility.
