Seeking the name of an original novel, one that can attract people…Seeking the name of a character…

In my creation, it is an urban fantasy genre. The name should be attractive…The story is probably about a ten-year-old assassin who failed a mission and was saved by a person on the brink of death. This person is a magician. After saving the assassin, he accepted the assassin as a disciple and granted him magic. It seems that he is kind, but he is trying to devour the assassin's natural remnant spirit (a person born with a broken soul). After the assassin escaped, many things happened to make the assassin stronger…
The assassin met a person who taught him martial arts, and then he cultivated both magic and martial arts…The names were not good, but those that were good added points!
