One Watch, I Trade Two Worlds

Luther, an ordinary office worker fired and broke, finds a watch that lets him travel between modern and ancient worlds. Using modern glass, he pays off a massive war debt. With basic education, he outsmarts top scholars and defeats legendary war gods. From a nobody, he rises to prince consort—dominating court, corrupt officials, and even charming the empress. Between two worlds, he turns modern knowledge into unstoppable power, winning the princess and climbing from bottom to top.
