This was something she had always been puzzled by; if it wasn't absolutely necessary, her mother would never have let someone else raise her child.
"Assassinations," Long Chengtian said gravely, "In those years, we lived in constant unrest. Mother often took us to hide from our enemies' assassination attempts, as well as fend off the Long Family's own attempts against us. It was impossible to guard against everything. As a mother and her children alone, managing to hide for a few years was already a challenge. Later, with the help of a friend of Mother's, we managed to evade their surveillance and lived for a year on the Aegean Sea. That was the most peaceful year we had before we were discovered again. One year, Mother secretly took you away, and you never came back. I think she had someone else raise you. I made a fuss and pleaded, but Mother refused to reveal your whereabouts, only saying that she had sent you to Eastern Europe."
