Feng Jianyu picked the painting to hang it back when something rough brushed on his palm. Considering the painting was a rare collective item, properly framed in pure gold and rosewood frame. How can there be a flaw in it? Moreover, it was not ordinary wear and tear but something deliberately carved.
He closed his eyes and brushed his fingers to feel it again what it was.
Viola! There are some letters scribbled over it, that can only be felt through touch.
"Mei, I'm telling you some numbers. Just check if that's the correct password" He connected his phone back to the safe and dictated the numbers.
A minute later he heard Xiu Mei celebratory voice, "Yes…. That's correct. You got the password"
Obviously, that pig brained Kong Da can never remember such a complicated password and get it carved on the corner of the painting frame. How stupid!
Jianyu touched Kong Da's thumb on the sensor to open the safe.
