Luke leaped towards the dragon god with a frown on his face, after taking care of the hand that delivered the blow, he'll deal with the body that released that blow! As for the system quest - he really didn't care about it, all he wanted was to kill the dragon.
Would he hold back? Not likely, with his eyes giving off an eeriely purple glint, Luke spun his upper body, swinging his sword madly to aim at The Dragon God's face, his brows knitted together.
The Dragon God, who wasn't standing idly frowned at this as he dashed back mid-air, his expression calm and relaxed as he watched Luke. He wasn't worried in the slightest, and wasn't able to hide his disdain.
Seeing this, Luke didn't give chase upon his sword unable to meet it's mark but floated suspended mid-air, his eyes narrowed and a smile forming on his lips.
