Luke closed his eyes and focused on his mana core to assess its condition. He was happy to see that there was no harm to his mana core after properly inspecting it. But he can't say anything about both of his hands.

In contrast, there are red scars all over his left arm, suggesting that mana had crept into the incorrect pathways and had no way to escape.
