No interest, move on.

I liked the beginning until halfway through 350 chapters, then it became messy and the story branched off in a direction where it became completely stupid, as if the author didn't know how to move his story forward, so he added things as he saw fit, but in the end I found it redundant how it was told, I found it inconsistent with the story from the beginning which had completely won me over. Too bad, for me there are only 250 chapters, the rest is useless to read.

I saw in the comments that the work is racist? But no, not at all, I don't know what you have experienced in life or if you are very naive, but all over the world every country, every nation, every individual has this little proud and "racist" side as you say but in my eyes I find it completely normal. The work is really great, the details of the characters, skills, talents, very detailed descriptions. The author surely has a high degree in mathematics, it is really a fantastic work for my part I fell in love with it. I look forward to the next chapters... and how the story will evolve.
