At some point Calamity God became a Heavenly Guardian of the Cleansing Incense Ancient Sect, but future generations had no knowleadge regarding his origin. There were many different legends. One stated that Calamity God came from a Burial Ground, another believed that he was born in the Ancestral Earth, while some believed that he was subdued by Immortal Emperor Min Ren from an external space.
In truth, however, Calamity God was a Heavenly Ancestral Snail and the only one who ever learned all Eighteen Solutions unlocking full power of his race. Thanks to it he became so powerful that only Immortal Emperor Min Ren was able to win a match against him. Calamity God was one of the two True Gods of the Mortal Emperor World (another one is the Heavenly Dao Academy's Realm God).[?]
Calamity God guarded the Cleansing Incense Ancient Sect for millions of years and his existence is one of the reasons why the Cleansing Incense Ancient Sect was able to stand strong for entire Emperors Era.
Around 50,000 years ago Calamity God suddenly left the Cleansing Incense Ancient Sect and completely disappeared without a trace and no one had ever seen it again. As for why he suddenly left after protecting the Sect for so long, no one knew. Even the disciples of the Cleansing Incense Ancient Sect during that period was unaware. It became a mystery without an answer.
In truth, after Black Dragon King killed Immortal Emperor Ta Kong and ripped the Heaven's Will, he requested the help of Calamity God to assail the Immortal Demon Grotto and retrieve Li Qiye's body. Calamity God died during the assault on the Immortal Demon Grotto.
