Honestly, this particular Hunter x Hunter fanfiction is one of my favorites among the Chinese adaptations. However, it's a crossover fic where the main character (MC) jumps to another universe, and I would advise stopping after the original Hunter x Hunter arc, as the story loses its momentum from there.
SPOILER AHEAD:
The MC abruptly and callously abandons all the friendships and connections he formed in his previous world, seemingly forgetting them without a second thought. The lack of character growth makes his personality feel stagnant.
As the narrative progresses, the presence of CCP propaganda becomes increasingly intrusive, particularly in the Marvel Cinematic Universe storyline. It becomes so overt that it's no longer a subtle touch, which can be quite off-putting.
Lastly, the love interest in the story is a young girl whom the MC adopts and raises from childhood, intending to give her a happy life. Unsurprisingly, she falls in love with him, and he accepts it, despite his role as her adoptive father. This unexpected turn of events, with the "grooming" aspect, crossed a significant emotional boundary for me.
In summary, while I could tolerate the political undertones and the MC's detached nature, the grooming dynamic was where I couldn't continue reading.
