In the fifth year before the Demon Calendar, the Demon King's forces were besieged by numerous human powerhouses.
At the brink of death, he laid down the most vicious curse.
"Seven Calamities will appear in this world. They will not vanish until the world is destroyed."
Later, the curse came true.
"Immortality" "Gold" "Storm" "Unknown" "Crystal" "Mutation" descended upon the continent one after another.
In the year 750 of the Demon Calendar, the Abyssal Demon God arrived in the mortal world. At last, all Seven Calamities had come to pass.
In the year 900 of the Demon Calendar, the Abyss launched its assault on the Heavenly Court. Almost the entire angel race perished, save for their goddess, but the Abyssal Demon God also vanished from the world.
