Rising From the Abyss: The Supreme's Revenge

Coveting the Supreme Bone, both Keanu Yates' best friend and fiancée betray him, stealing it, and then sending him off a cliff to his end. Fortunately, the Nether Supreme of Skyward Gate saves him, and Keanu breaks through the God Realm as his power reaches its peak three years later. He rises as the new Nether Supreme, the man who holds the most power among all people. Getting rid of anyone who stands in his way, he returns to Drieso to investigate the truth of his death.
