In olden days, Zhao lived as a somber money-lender. Long had he stockpiled things that had been given to him in pawn, and as he searched through the piles of items again one night, he found an ancient copper lantern that had been glazed with a cracking green laquer. Knowing he needed better light in his office, the rat took it, polished off the dust of the ages, filled it with fuel and lit it. Little could he imagine what happened next. The incensed oil emitted an eerie fog, and when he breathed he understood. He understood... all. He then knew what it was he needed to do.
