"Ainsley's New Bodyguard"

Ainsley did what the Godfather suggested to her. She looked at Martin's chest and saw the oath words chaining the young man's soul. 

The soul was similar to a flicking blue fireball, definitely unique to each person. But those words forming a chain around the fireball was the proof of a soul oath. 

When Ainsley saw the chain, her face paled. 

[Martin still has...the soul oath.] The baby gulped and tried to keep her calm. 

[This impostor...can even copy the soul oath.] 

! 

The Godfather shuddered. He overheard what Grandpa Yofan said about a top-tier mimicry ability user that could even copy the target's soul oath…

He didn't think he would find one infiltrating the family! 

[So, this guy...is the one that old man warned you about, right?] 

[Right. I'm sure that he's an impostor because he didn't use any of the real Martin's abilities...and yet he still had the same soul oath.] 

This spy is an elite one!
