Lin Shen was completely flabbergasted, thinking, "Has Tie's brain gone bad? Even if his brain's broken, his eyes should still be fine, right? Or is it that he's never looked in a mirror and doesn't know what he looks like? We don't share a single similar trait, how could we possibly be biological brothers?"
However, upon further reflection, Lin Shen thought that given Tie's current half-human, half-metal state, if it were himself, he probably couldn't accept it either. It was understandable that he didn't like looking in mirrors.
"Tie, look, I have single eyelids, and you have double eyelids. My hair and pupils are lighter in color, while yours are darker. Even our nose bridges are different, yours being higher and mine smaller. Not a single facial feature is similar, how could we possibly be biological brothers?" Lin Shen pointed to his own face, trying to remind Tie as gently as possible that they looked nothing alike.
