Dual Transmigration: From the Start, One Pound of Millet for a Bride

[Villain, scheming, historical, transmigration, dual transmigration] During the reign of Emperor Jing of the Daye dynasty, natural disasters struck one after another, leaving the people in dire straits. The protagonist, Lin Mo, accidentally transmigrates to ancient times and obtains a dual-world transmigration System, allowing him to travel freely between the ancient and modern worlds. He carries ancient goods to the modern world to sell, then transports modern goods back to ancient times, making a fortune in the process. He spends lavishly in the modern world, while buying farmland and mansions, purchasing official posts, trading in slaves, and exploiting the people in ancient times. From the start, one jin of millet gets him a wife, and for every ten jin, he gets one extra free. As he makes money, he also recruits troops and builds up his forces, becoming sworn brothers with princes and noble clans. The foolish emperor becomes his father-in-law, and the princess becomes his beloved wife. [The protagonist is something of a villain. The story focuses on recruiting troops, farming, taking wives, and building power in ancient times, along with showing off and face-slapping. Readers who dislike somewhat villainous protagonists should steer clear. There is no female lead in the modern-world storyline.]
