For the low rating of this fanfic I thought it would be very bad, but after reading more than 820 chapters I concluded that it deserves a much higher rating, the story is good, there are no big holes in the plot, the interaction of the characters are good, the MC is not it gets strong very quickly but it's not weak either, there are many disagreements between the characters and that makes it a little tiring, but it didn't spoil my reading.
I've seen fanfics much worse than this one with a high rating, so I recommend you read it
