Jack, an outdoor store owner in modern Texas, USA, inadvertently established a cross-time connection with Elias, a down-and-out prince who was dying of thirst in the other world "New Eldorado" through an "antique cowboy boot" from the 1880s. Faced with the encirclement and suppression by gangs and oppression by mining companies, Jack used modern equipment such as riot shields, bright flashlights, and bear repellent spray from outdoor stores to help Elias turn defeat into victory and repel the bandits and a thousand mercenaries. With the blessing of the "Voice Conveyor" and "Heavenly Punishment Fireworks", the two developed from material transactions to fighting side by side, and finally helped the prince establish his country and become the king.
