The last thing I can remember where I read this novel is after the captain had his hand eaten by MC and MC regenerated(?) his hand. Then the captain had a mock battle, he used his hand to punch and it sent the opponent flying. Thank you for your help.
That should be 11-13 or somewhere around there. Edit: The thing with the hand didn't happend in the ... Park? of the dragons? That weird shit. Ugh, the updates are so slow I forgot.
Yeah, you're right She ate his hand in a cave at a mountain, then she realized she what she had done, she regenerated(?) his arm back.
