Thriller: I Am the Strongest

(The protagonist in this book is insane, takes pleasure in doing evil, and has unhealthy outlook on life. Be careful before entering!) ………… What will you do when horror suddenly strikes? My answer is, play! Play like crazy! My life is gloomy, but horror brings me joy! It's scary and gives me the motivation to move forward! And let me see through the essence of this world! As long as you are strong enough, there is nothing you can't do! And I am the strongest in this world! Monster preview! MONSTER! [Later period invincibility + single female protagonist + first person + slow pace + please point out any irregularities that are not consistent with common sense, and they will be rectified if necessary] This is the story of a person coming from nothing, and then from being to nothing...
