This dark cuisine tasted alright, though its appearance was too horrifying, with those fish heads looking as eerie as if they were alive, even twitching inside his mouth as he ate.
But it must be said, it was this dish that gave him the physical fitness of a normal person, otherwise, he might have even thought of using it as a weapon, given how the eerie glow of the fish eyes was quite useful when he originally went to get food.
As for the idea of enhancing this dark cuisine to boost its effects, he had contemplated it but never implemented it because, with his original constitution, eating an enhanced version would definitely have killed him since it was too potent. It had to be gradually escalated.
First, eat the unenhanced version, then eat the enhanced +1, and then move on to +2, +3, etc., not jumping straight to +12 since such a leap would undoubtedly be fatal.
