"Qin Yi, I believe what you said, that no one can swap it out unnoticed. But it doesn't stop anyone from stealing under supervision." Long Hai sneered.
Qin Yi squinted slightly, "From what you're saying, did I imitate the Second Prince's handwriting and switch the secret message?"
"Isn't that so?"
Qin Yi said indifferently, "Do you have any evidence?"
Long Hai laughed disdainfully, full of mockery, "Qin Yi, you probably don't know that there's a mark between the Second Prince and my letters, but the secret message you gave me doesn't have it."
Qin Yi squinted; damn, this Yun Baixuan is truly cunning.
However, he couldn't figure out that the letters Yun Baixuan gave him had been carefully checked, revealing nothing unusual.
"What kind of mark?"
Long Hai took out another piece of letter and unfolded it together with the letter Qin Yi had brought, "Qin, can you see anything?"
