I Am Invincible in the World, What's Wrong with Having Hundreds of Millions of Maids?

Shen Mo accidentally traveled to Wanjie Island and became the "Lord of Wanjie", shouldering the important responsibility of running Wanjie Inn and Tianji Tower. The Wanjie Inn connects all the worlds, and through the mysterious Wanjie Cave, people from different worlds gather here. Shen Mo uses lifespan as a "toll" to provide cross-border passages for visitors. At the same time, he uses the Tianji Tower to announce the secrets of all realms, triggering interactions among the heavens. They come across borders, some seek martial arts, some seek immortality, and some just want to see what their lives are like in the world next door. And Shen Mo, sitting behind the counter, watching the heroes from all over the world making trouble, occasionally saving a beauty and coming back as a maid. Open an inn that connects all realms, listen to the secrets of the heavens, and see the scenery elsewhere. By the way, make this Ten Thousand Realms Villa the most stable place to stay in the world.
