Not bad, but not quite what I expected. Over 150 chapters, I read mostly about everyday life at school from the perspective of different secondary characters, the author is either nostalgic himself or tries to play on the readers' nostalgia, but for me, as a non-Chinese reader, it works poorly and such moments feel boring.
One good thing here is that the author does not use so many templates from other immortal urban novels: there are no constant slaps in the face (although the hero often takes revenge), there are no sects or families hidden from the world, there is no spiritual energy revived and there was no incredible harem while I was reading.
