Kaiser with Jacob and Alia, who were also done with their sides stood amazed seeing Karna, the guy who had just not to long ago told them he didn't remember how to wield a sword was now attacking in such a risky way.
Karna, on the other hand, was focused on something else—a unique kind of notification that he got.
<Ding! You have killed an injured Lev-4 Grebber.>
<Mark of the Dead is analysing kill's cause.>
<Mark of the Dead has deemed kill as yours.>
<You 113 have gained exp.>
<Required 270 400 experience to level up:>
'What the duff, System? What does this mean? Karna, upon seeing the new added set of notification after killing the level-4 grebber asked the system feeling confused.
The system then began to explain to Karna that the Mark he received had two primary functions.It also mentioned that it was about to explain this to him when Karna had stopped it just before the bloodhound began to chase after them.
