Give and take
"Theft of what?" asked Fu Yu Sheng, though he had heard about someone trying to steal someone's identity card and maybe there were some weird cases where someone would pretend that they were someone else but he never thought that someone could even steal someone's entire existence.
"It's the darkest of all magic," said Song Yan as she tried to remember what Gu Yujin told her about the ' Stolen Existence Ritual'. " It requires the blood of the person you want to steal existence of along with their birth character and as well as a strand of the person whose identity the person intends to steal. Once these things are in the hand of the culprit they can easily go through the rest of the ritual, no one would even find out about what is going on even the person whose identity is being stolen because the ritual does not harm either of the parties, so until the entire thing is completed nothing will happen as it happens in other rituals."
