Karwenz saw nothing but pale white in front of him after returning from death. He felt some ringing in his ears and also an uncomfortable and powerful urge to vomit due to the condition of this physical body.
It was expected that his vision wouldn't recover immediately. It would take time getting used to eyes that hadn't been used for quite a while. This physical body that Karwenz had prepared for himself had been sleeping for almost a month.
This body hadn't eaten or drunk anything for the past month. Plus, due to the special condition of this body, the mortal's body had already reached its extreme limit.
If it wasn't for this body originally belonging to an excellent swordsman, then "he" would likely have to first rest properly for half a year in order to recover.
"Bro, I'm going to play outside now."
