The protagonist isn't merely a powerful figure in one domain. He's the "administrator" of the Myriad Worlds, able to switch seamlessly between different worlds and identities. Urban face-slapping, post-apocalyptic survival, lavish spending as a tycoon, domination of the entertainment industry...! In the main world, Lin Feng becomes a legend who secretly controls the globe. With heroines from other worlds, including an urban empress, a post-apocalyptic Valkyrie, and an ancient female emperor, he spends his days occasionally managing worlds and, most of the time, living a carefree life.
