She wasn't his food, so he decided to indulge her by replying. He said, "Today is your lucky day."
His will moved as an ocean of force. This ocean submerged her and grabbed her. She became frozen, unable to move an inch. Then the force dragged her down to the dark side of the void universe, and the head submerged itself again.
Only the immortal continent was still there. Nothing had been harmed on it. It will be difficult for anyone to notice that a fight had technically taken place here.
It wasn't actually a fight even though the Supreme Origin god had tried to resist. Her attempt at resistance was simply insignificant.
The whole process of capturing her was as easy as catching a chick. The Supreme Origin god couldn't even struggle. She didn't even know when she was captured. She only felt her world slow down until it stopped completely.
She was still aware, because of her Supreme law. But short of that, there is nothing else that she can do.
