Karna was still unconscious but like before he can still communicate with the system even if his body was out cold. He was just waiting for his body to get enough strength to wake up.
But while he was minding his own business system, a voice rang in his mind taking him aback and then he remembered that Eklavya was still waiting for him under the tree.
"Wait!? What happened now? Eklavya got an epiphany? Well that's reasonable seeing how talented he is but who is another one who got enlightened? And why am I getting benefits of it?"
Karna spoke sound but no one here to hear him out, and the system being his system not answered him making him go crazy with the questions arising in his mind.
He understands that Eklavya getting an epiphany, Though it was still a surprise but it was understandable as his talent was already very high and on top of that he even increased so it was just about to happen.
