The pinholes were extremely fine, and when indoors, one couldn't see them at all; it was only under the sunlight, when the light shone through, that they appeared before Chu Yu's eyes.
And the pinholes formed a character.
Chu Yu's eyelids twitched, and remembering that Hua Cuo was beside her, she quickly pretended to casually tuck the piece of paper into her sleeve and returned to the carriage with Hua Cuo.
They had originally planned to visit Wang Yizhi and then enter the palace. Chu Yu did not intend to change her plans. Upon entering the Imperial Palace, she stopped again, took out the piece of paper, and confirmed the character against the light once more.
Chu Yu furrowed her brows, and after a long time, she slowly folded the paper and meticulously stored it away with a bit of confusion.
What was Wang Yizhi trying to tell her?
Why use such a covert method to hide that character within the message?
