We can talk now..

"Arghh.. tsk tsk~" Sounds of pain escaped from the giant's mouth, while his eyes started to open, and he unconsciously raised his hand to place it on the place he felt the most pain from, the back of his neck...

"If I were you, I wouldn't do this..." A voice sounded beside the giant suddenly, the giant stopped his hand in the middle of the way and looked at the source, it was Robin...

Then he continued to speak as he grilled what looked like a deer, "I attached a wind blade talisman on the back of your neck, with nothing but a thought I can activate it… 

I know your body is strong, but the blade will cut at least an inch or two before it stops, damaging the spinal cord means death for any living creature no matter how powerful he is, so please, for your own good... put your hand down and leave the talisman alone."

The Giant lowered his hand and started laughing, "Hahaha, cough, cough, coughhhh... that was unnecessary..."
