Tang Wen was transmigrated to the Da Chu dynasty and became a deadbeat noble and the lord of an abandoned island.

Fortunately, he had the Landlord System and was able to return to the modern era. After making his first pot of gold, he returned to the dynasty to make even more money.

He built waterways, expanded farms to plant herbs, and raised tigers and red-crowned cranes.

“I have to build roads as well… I can keep coming back and forth between two different times to make money, but I need more people to work for me…”

“Come and work for me. I can provide food and shelter. I even have pills for you to get stronger and I can even help you find the love of your life. Become my slave.”

Just like that, millions of people started to work for Tang Wen.

“Sir, don’t you know? Almost 80% of Linghai County now belongs to Tang Wen.”

“My liege! Tang Wen has taken almost all of our land…”

As Tang Wen’s influence started to spread even further, he said, “I don’t know how big my land is. All I know is that I have a new title, the Landlord.”
