The scorching sun blazed, in the depths of the Southern Border's Endless Mang Forest, the trees loomed ominously, ancient trees with trunks ten people could barely wrap their arms around were visible everywhere, and dark green vines coiled around the trees climbing everywhere, stretching among numerous ancient trees like fat, wandering monstrous pythons, from which occasionally dripped green sap.
Most areas of the Endless Mang Forest are unknown lands where no one has ventured since ancient times. Over billions of years, fallen leaves have continuously accumulated and decayed on the ground, forming an unknown thickness of humus layer, and countless dazzling miasmas rise from the ground, forming colorful and highly toxic miasma clouds as time accumulates in the depths of the jungle.
