This book is broadly divided into three stages: elementary school (yokai), middle school (aliens), and high school (people from other worlds). The power scale gradually expands from Earth to the entire universe, and then to other universes, with almost no connection to the plot.
As for what kind of story this book tells, in short, it's an everyday-life story about an invincible protagonist gradually reflecting on his own life. At least, it's everyday life to him. Though it's a slice-of-life story, the destruction caused whenever they fight is unquestionably world-shattering.
The author doesn't just throw things together at random. They decide whether to include a series based on whether it fits the original setting, and most of them appear in short segments that expand the worldbuilding.
(Attention! This book has either no female lead or a single female lead! The author hasn't decided which yet, but it absolutely won't be a harem collecting women!
The fire is about to die down, but the king is nowhere to be seen 😭😭😭
After so many years, and with all the ups and downs, is it finally over?
Where is the author? Any new books?
He was castrated?
Looking for books similar to this one, from Tomato, Qidian, or Xirang. I've already read "The System Arrives at the Great Ascension Stage," "The Mysterious Immortal," and "The Mysterious Sea." I've also read Tomato's "National Destiny."
Have you already given up?
The story is finished!
Heroes, ah, that reminds me, Feilu also has one.
