On his third day in the post, Gong Yanzhou went straight to the materials yard at Lot 2 of the Fengshui Phase One project. Pi Jiantang handed him a neatly copied ledger, hoping to fob him off. But Gong insisted on seeing every original weighbridge ticket from after midnight. He laid them out and went through them one by one, calculating that 141 truckloads of crushed stone had arrived, totaling 1,302 cubic meters, 22 more than reported. The truck numbers were even a continuation of those in yesterday's ledger. He then checked the shift logs and fuel records. Two excavators running for eleven hours should have used 330 to 396 liters, but the books listed only 132 liters. Two hundred liters of fuel had vanished into thin air. Pi Jiantang's smile faded. Gong Yanzhou told him to open the fuel tanks, but he didn't move. Which machine had those 200 liters of fuel gone into, and where had it been driven?
