When Lu Yuan, a down-on-his-luck stall owner, is being bullied by thugs, he accidentally activates the Myriad Worlds Trading System. Through an old-fashioned radio, he establishes a connection with the war-torn Great Yuan Dynasty and meets Chu Zhan, a military general trapped in a desperate situation. Lu Yuan continuously sends modern supplies such as flashlights, walkie-talkies, high-voltage electric batons, building materials, and electrical appliances across worlds. Using overwhelming technological superiority, he drives back powerful enemies and helps Chu Zhan break free from the control of a corrupt imperial court, transforming Soulbreak Valley into an impregnable cyber fortress. Lu Yuan then sparks commercial wars with his unique products, drains the Great Yuan's national treasury, and dismantles its national strength. Ultimately, with technology and power far ahead of his era, he destroys the old dynasty and joins the people and soldiers of another world to establish the mighty Divine Abyss Cyber Dynasty, whose power commands respect in every direction.
