Who said that Bai Chen only heard such humiliation after transmigrating to this world? No, that assumption was not true because Bai Chen had often heard such insults in his previous life.
["Look! That kid has a pair of blue eyes! He's so scary!"]
["Hey! Don't go near that kid! My mom said he's not his parent's kid because his parents don't even have blue eyes like him! He definitely isn't his parents' child!"]
