Tomb Robbing Mysterious Coffin

Tomb robbers are generally divided into two major factions, one is the northern faction and the other is the southern faction. I am a restaurant owner, but privately I am in the antique business. An old photo drew me into a huge conspiracy. The ghost coffin, the real and fake Mausoleum of Qin Shihuang, the thousand-year-old rice dumplings... What secrets are hidden in the photos? Who is the real mastermind?
