The Great Siming is an innate god who was the first life ever to exist in the universe, born with the power to bestow and reclaim life. Ever since his birth, the universe was bestowed with the essence of life, hence, making him the Deity King of the Dao of Life, and the source of all life in the universe. He was an incredibly strong existence that ruled over the Deity Kings of the Prehistoric Dark Ages, only to meet his downfall when he was betrayed by a few Deity Kings.
He was revived when zhong yue was researching dao language from dark age. Later he co-operates with zhong yue to change their fate of being killed and to open the road to dao world.
