The formless ancient world was infested with despicable demons. They hunted and feasted on mankind, keeping the human civilization constantly in a weak and suppressed state.

During the first known year, a magical mountain descended into the world from the realm of the Gods. Carved on this enormous mountain was a message: ‘Heaven Prevails’…

After the Grand Descent, a name that was given to the descending of the mountain, the Three Great Sages made their ways to Mystic Mountain where they learned to harvest what we now call magic, establishing the Mystic Cults and eighty-one sacred shrines to help aid mankind with the cult’s mystic powers against the eternal fight to the death with demons.

Cliche. Another monster progression story. That was probably what you thought when you read the title of my story. And, I can't lie, for the most part, it probably is.But, what else am I supposed to do when I've been thrusted into a world that could kill me in an instant? There's nothing to do but to progress, to devour and evolve. You would do the same too.Such is the basis of a monster.Such is the right of any living being.So that's what I did. I ate, I killed and I hoarded anything I could get my big limbs on. Friendship, allies and love? There used to be a little god calling himself “Heaven's Equal” who spouted of such things, before I ate him. The world went pretty quiet after that.Follow my story. Read for yourself how I evolved from a little monster in a lake I thought was the ocean, all the way into the Titan Of Destruction.What To Expect:- A relatively quick progression story- Ruthless, I mean - Fang Yuag levels - of ruthless protagonist.- A system? that grows stronger along with the protagonist- Big Monsters Duking It Out, with minimal humans/beastmen/elves, etc. . .focus. Basically, monsterverse without annoying ass humans ruining the show.- Did I mention that the protagonist was pretty evil?
