People in a Different World, Professional Time Traveler

Mu Chen traveled to a different world. In this world, the trajectory of life is determined by [vocation]. A farmer's son is a [farmer] from birth, and a noble's son is a [noble] from birth. If you want to become a [warrior], you need to learn combat skills. If you want to become a [mage], you need to learn spells. Warriors hone their combat skills, mages study secrets, thieves steal chickens and dogs, farmers work diligently, and people climb on the established roads, building a stable and strict ladder of order. The elves resonate with the whispers of nature in the forest, the dwarves forge the veins of the earth at the bottom of the mountains, and the human kingdom composes an epic of conquest and trade as it expands. The demi-humans, on the other hand, struggle to survive between slavery and resistance. What supports these thousands of phenomena are the [imprints] and [trajectories] that circulate in the world. Combat skills, spellcasting, forging, and even healing are all guided by the resonance mark. And Mu Chen's vocation is to be the only [traveler] in this world.
