The first 100 chapters were interesting and even a little funny, but then in a very short period of time the whole routine of the author became boring, or everything that was interesting became a boring routine.
What was happening became very monotonous, for all sex one metaphor until the end of the novel, in the promotion of interesting little: it is simple, few features in its capabilities, +100 billion trillion points (too frivolous numbers, they simply cannot be perceived normally).
At the moments when the author could develop secondary directions of the plot (his boat, the development of the received world or his inner universe) everything again came down to metaphors of sex and getting a stronger thigh that can be hugged.
At the moment of getting into the higher mythological world (myths only of the East/China) everything came down to the appearance of all sorts of mythological characters and the appearance of a chat room, again associated with different near-mythological Eastern/Chinese worlds. And all for the appearance of new female characters, although there are many old ones for the hero, because he does not use clones or incarnations.
As for the characters, I can only say that they are all just decorations for the hero's journey. The only unique thing about them is their names, and not always. Otherwise, they are empty shells with a semblance of character that disappears after sex, because after that all the girls turn into a puddle of insane happiness whose only desire is for the hero to continue practicing.
In essence, a boring drag with often incomprehensible references and a pre-determined ending.
