Just like the envelope, the white card was extremely clean.
Only two words were written on the card:
'Remember it.'
Glued behind these words was a small clump of black, hard hair.
A few crusts of brownish blood were stuck to the hair, which emitted a choking scent when brought close to the nose.
'M·K·S', three letters written in cursive using black ink were on the bottom right corner of the card.
From a design perspective, this card utilized the concept of 'simplicity' to the extreme.
Because of this, the little information revealed on the card was extremely striking.
"From what you've just said, do you know what's on the card?" Zheng Qing stroked his bare chin, mumbling, "I feel like I've seen this scent on the card somewhere... it feels familiar."
"I have a guess. But I can't confirm it until I do some later checks." Xiao Xiao found the letter quite interesting. He wolfed down his breakfast, then eagerly pulled out his notebook, suddenly asking, "Do you know who M·K·S is?"
