One Watch, I Trade Two Worlds

Lin Dong is a low-level office worker who has just been fired and has nothing coming in. He comes into possession of a wristwatch that moves him between the present day and an ancient dynasty, and he starts carrying goods across. A load of ordinary modern glass covers a war indemnity that had been crushing the treasury. Nine years of compulsory schooling is enough to leave the court's senior scholars with nothing to say, and objects he brings from home, which everyone there takes for divine implements, settle fights against men reputed unbeatable in war. His standing climbs. He is made consort to the princess, which puts him inside court politics against the chief minister, and the empress takes an interest in him as well. In the present day his circumstances change too, since the money and the leverage travel both directions. He keeps both lives running at once, using what he knows about how things are made.
