The Delivery God of Two Worlds

After a fatal accident, Leo awakens with the Delivery God System and gains the power to travel between two worlds. Time-traveled into a famine fantasy realm, he completes delivery quests, saves a girl from crushing debt, and turns rare resources into great wealth. Gold in another world? He takes it. Overpriced medicine in reality? He buys the factory. By trading between worlds, he rises from courier to tycoon and begins his path to godhood.
