Bab 88: Upgraded Soul Contract

"Aaaahhhh!"

Nathan had expected a more uncomfortable feeling than a proto-class since he had found the same thing when he absorbed the juvenile class.

Never in his wildest dream would he think of pain when absorbing a core.

His eyes were rolling back, leaving only the white behind. His body first arched up before it started writhing on the bed. He kept clutching his chest as the pain was concentrated in that part, as if the core was stuck on his trachea.

The pain was not ordinary. He managed to endure the excruciating pain from getting stabbed, yet Nathan actually screamed like never seen before. The pain must be unimaginable.

"Oi, stupid dog! What is happening here? What is going on? Heal him!" Fenrir panicked.

"I don't know. This must be a reaction to eating the core. There should be no problem." Anubis gritted his teeth. He was using his healing ability, but there was no effect.
