The girl is no longer named Jing Ke. Because she was criticized as being against history, she changed her name to A Ke. She was originally set to be Jing Ke’s sister in Glory of Kings, but she just inherited her brother’s name

So Jing Ke’s line before changing his name was “Not the Jing Ke you remember, but he is no different in lethality”

After changing his name to A Ke, his line was “Not the assassin you remember, but he is just as deadly.” The degree of fatality is no different”
