The slender briefcase is easily opened with the passcode you were given, inside of it are a pair of polymerized
clear plastic sheets, sandwiched between them a simgle sheet of parchment, looks to be very old and handwritten in Chinese.
Looking at the parchment you see it appears to be a page from a ledger, perhap from a trader or antique dealer. Despite
its' obvious age there are a few entries scribed within the past 30 years.
