Modern antique dealer Zhou Ye, thanks to an ancestral pendant, is able to travel back and forth to Wangchuan, an isolated city suffering from a three-year severe drought. Faced with corpses littering the field and monopolies by powerful clans, he uses the resource disparity between the two worlds to save the world with dimensional reduction, opening porridge stalls to gather public support, leveraging grain prices to eradicate corrupt officials and grain tyrants, and forging divine weapons and heavenly thunder to crush the rebel army besieging the city. In the modern storyline, he also uses ancient rare treasures to counter-kill wicked relatives who seized his property and capitalist tycoons. Between running for his life and counter-attacking across dual worlds, he not only firmly sits as the "Master of Wangchuan" and a "hundred-million-yuan collector", but also gradually uncovers the shocking mystery behind his father's old case and the pendant.
