The Demon Emperor coughed up black blood. His facial expression twisted in pain.
His chest got pierced with something that he did not see coming. He wasn't even able to sense it, much less defend against it.
What's worse is that the Miraculous Son got impaled by him. He could literally smell and feel the putrid holiness he was exuding and it was making him sick.
Thus, even though it pained him so much, he forcibly dislodged himself from the crystal arrow that pierced his chest.
It left a gaping hole in there. He's pretty sure that the arrow destroyed his heart. But thanks to his regenerative ability as well as his false immortality, he survived this blow even without a heart.
The Miraculous Son is also at the same...
Coughing out more blood, the Demon Emperor heard white noise. He felt nauseous for a bit and his vision blurred.
