I remember the typical fanfics in which someone reincarnates as a celestial Dragon and imposes his government on the world, it would be interesting if someone reincarnates as a super powerful celestial Dragon with a system and when it seems that he will win, the Gods intervene and eliminate him, by the way I like the Gods in this fanfic, they are imposing and they are basically incomprehensible cosmic horrors, here the Gods are immortal beings capable of affecting the entire universe and they are creators of universes
