What is it like to own an abandoned oil town in the West? At first, Xu Xing simply wanted to provide some convenience for travel enthusiasts and camping enthusiasts traveling by car to the northwest.

The stall has been upgraded to a convenience store with a unique style, the instant noodles cooked in an earthen pot have been transformed into a restaurant that provides hot and authentic beef noodles, and the shack has been transformed into a hotel that is unique in the country and can look up at the deep starry sky. The tire point has been upgraded to become a gas station and maintenance station….

after that,

The town unknowingly became the size of a small county town…sixth tier, fifth tier, fourth tier, third tier…a few years later it became the only new first-tier city in the northwest Gobi Desert…

- Description from novelbuddy

Transmigrating into a world of cultivation, you find yourself at the lowest rung of the sect's hierarchy. Everyone wants to bully you to gain some benefits. Fortunately, there are always a few junior brothers and sisters who are 'generous and understanding', allowing you to improve peacefully and secretly grow stronger. Years later, unbeknownst to anyone, you successfully become a deity within the sect. This day, your master visits you at the sect's request.'The upper echelons of the sect believe you have been diligent and loyal over the years, and though your strength is mediocre, you are an honest person, so they've found a marriage alliance for you.''An alliance marriage?''Not exactly. The other family has a rule: marrying into their family means taking their surname.'Is this... becoming a son-in-law who marries into the wife's family?

The days where adventurers would roam the land and grow strong are long gone. More than 99.9% of the world's population is level 1, and in fact, leveling just isn't something people think about anymore, as almost every spawn point on the planet has been gone for close to a thousand years. Only the elites, the super rich, or the super lucky have access to spawn points, and because of this, they are like Gods among men: like superheroes. For people like Zach, life is a mundane, ordinary experience of getting up, going to school, working, and then going back to bed. But that's all about to change when he stumbles upon one of the only unknown spawn points in existence. And in doing so, his life is about to descend into a wild chaos he never could have expected. (Lit RPG, fantasy, action, slow burn)

Crossing to One Piece world, he became Roger’s younger brother.
