Taking down a Grandmaster Level Soul was something that was almost impossible for Adam who had only recently strengthened his Soul Form to become a Master Level Soul, especially since the Grandmaster Level Soul was an Evil Soul that was powerful and skilled.
However, Adam couldn't allow it to roam freely and it was his responsibility to take it down after finding out about its existence, while it would also feal a blow to the Blood Moon Group.
Suddenly, Adam sensed something appearing near him and instantly became alert.
It was a portal from the underworld and usually, when sensing them, Adam could tell that it was a mere mindless Death Wraith, but now he felt danger as he jumped away from the portal that appeared near him.
The existence of an Evil Soul that was that powerful in a Mortal Realm would definitely alert the underworld, and Adam didn't want any issues with the underworld.
