Within the vastness of the Three Realms created by Pangu and molded by Nuwa, all things are possible. This is the land that gave birth to countless myths and legends, including those of Sun Wukong the Monkey King, Hou Yi the Sunslayer, the Buddha Tathagata, the Jade Emperor, and more. This was a realm of asuras, devas, gods, Immortals - and the world that Ning found himself reborn into.In his past life, Ning had been a sickly youth, but the philanthropy he had carried out resulted in him being blessed with a new life in the Three Realms as a deva of the Heaven Realm - or at least, that was what was supposed to happen. A series of accidents led him to instead be reborn within the noble Ji clan in another part of the Three Realms, Swallow Mountain. This certainly seemed like a downgrade from being a deva, but he had powerful parents who loved him, maids who doted on him, a mighty clan behind him, and a cultivation technique from a benefactor that was supposed to make him stand out even amongst the devas, to say nothing of the cultivators of this strange land.And yet, not all was well in Swallow Mountain. Monsters abounded everywhere, ravaging the land his clan was sworn to protect. His own clansmen enviously eyed his position, while the other clans of the area hungrily eyed the Ji clan itself. Strife begins to stir as the shadow of war looms. Quelling this was not a task for a mere boy - it would take a true warrior of Swallow Mountain!
