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!
