I Became Kurama in My Dreams

The protagonist of this classic novel just gets a cheat code, and then a superpower bureau pops up in reality. Didn't the author know anything about current novel trends before writing this book? Why would they still use such a toxic plot?

I really enjoyed reading the Naruto world, for about thirty or forty chapters, but then it jumped to modern-day cats and dogs, and I couldn't keep reading.

Everyone knows that firing a Tailed Beast Ball generates thrust (that is, the Nine-Tails shows signs of being pushed back when firing a Tailed Beast Ball). Could we extrapolate this to the Nine-Tails, allowing it to fly into space by continuously firing Tailed Beast Balls with its rear end facing upwards? And since it's a chakra being, it doesn't need to eat, drink, or breathe air, and it also possesses infinite energy... Oh wow!

Does the author consider the Six Realms to not exist?

Thirty-odd chapters of writing about superpowers, then national control, the constant threats of joining some so-called school or being under 24/7 surveillance with no privacy or freedom, and using superpowers is illegal, leading to jail time and research. What's the point of writing this? I'm withdrawing it.

The beginning was going well, what was you thinking when you went and started writing about real-world superpowers? This book is basically doomed to fail.

What kind of deep-seated hatred and resentment is this? 24-Hour surveillance, unconditional cooperation with research institutes—how has this organization survived this long? Write more; your self-indulgent musings are fine for you to read, but I'll just leave it at that.

Didn't the author even read the book after finishing it? Is this protagonist insane?

I don't understand. Don't these authors read novels? Can't they just look at the novel's comment section to see what the "criticism points" are? Why do some authors always seem to touch those sensitive spots? I can accept superpowers in real life, but how can you write a story about traveling between two-dimensional worlds like this?

Learning eight techniques in a week, and then opening the Death Gate and still not being able to kill even the lowest-level, some kind of so-called superhuman? What kind of Naruto fanfiction is this?
