The supporting character's harem is very normal - Chapter 182 You guys... are really weak.

After an accidental death, in order to continue to live, Gu Bai had to choose to go through various wonderful books to complete tasks.

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.

In a world filled with abilities and superpowers, Moby Kane, a 16-year-old boy, is an orphan who is living his life with a little too much optimism, trying his best to get by.

Due to him having no ability, he had been bullied and tortured every day. However, for some odd reason, he never complained and always stayed happy no matter what. It was almost unnatural.

On one cruel day of immense pain, he realized that the world is a brutal, unforgiving place, making him regain his lost senses.

In his moment of desperation, a miracle happened.

[ You have unlocked the Demon System ]

Now that Moby has the power to change his cruel destiny, how will he use it to get back at the world that wronged him on the road to becoming the demon lord...

IMPORTANT MESSAGE TO NEW READERS! PLEASE READ!

My first few chapters' writing quality is very bad and lackluster but gets much better as the novel progresses!

Also, the first 5 chaps are kinda similar to vamp system but the story and settings differentiate after that into their own thing past that point! Hope you stick around! :)

Quick note! many people in the world are cruel and almost psychotic but there is a good narrative reason for that, it will be explained later on in the novel I promise! :D
