A forgotten cave in the sea of Time

Fifty years ago-- The Outer Beast Territory within the Black Sun Kingdom

This area is famous for being untouched by humans as it was home to countless beasts whose levels range from 1 to 10, those beasts take advantage of the large area in the outer beast zone to hunt each other and even hunt some unfortunate humans

The number of humans who enter this area looking for an easy hunt or a quicker way to reach another kingdom is not small, But the number of humans who actually get out of it alive does not even reach a quarter of that number. Only experienced Hunters who can detect danger before it occurs or high-level cultivators can roam here freely. After all, it is a forbidden area for humans, only someone who is a Marial Knight can walk around here without fear.

However... Two individuals have been frolicking in that area for a very long time as if it were their backyard.
