Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos).

However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

It burned an entire kingdom to the ground for petty revenge against the humans. It ransacked the Board of Sorcery, hoarding all the cores in their treasury to ease its greed. It killed and destroyed a God for entering its territory without its permission. In a cavern within the Great Aeternus Labyrinth, a reptile seemly like any other hatched from its egg. With a growing intellect it shouldn’t have and adaptability traits that is impossible for its current tier of evolution, it began its life surviving and growing stronger. Read as this reptile mutate and evolve. Watch as it change the world of Atinen, as it usher the world into a new age of chaos and destruction as well as prosperity and hope. *** I know you guys are tired of fun monster evolution stories where the monster becomes increasingly less monstrous, and eventually they're just a more spicy version of a human and it stops being a monster evolution story. I am too. This story is not about a human who was hit by a truck and reincarnated into a world where he so happens to be a monster. No. This story follows the Mc who is a monster with a monster’s mentality and POV. However, reincarnation is apart of the story. Additionally I have taken certain elements from some of my favorite non-human novels and stories such as: Chrysalis, Kumo Desu ga, Nanika?, and even Re: monster. Point is, I’m incorporating a large amount of ideas and flipping them to fit my story.
