Great Yin Dynasty

This is the Great Yin Dynasty, outwardly prosperous and stable, but with undercurrents surging beneath the surface. Since the constant appearance of "transmigrators," order and culture have begun to shake.

The Soul Purification Bureau is a government-affiliated "Transmigrator Registration and Placement Bureau." All who come to this world must register here, record their origins and identities, and learn the local culture, seeking a place to settle. If they take over the body of a local, they must confess their identity to the original family to gain recognition. The Soul Purification Bureau is both a solemn regulatory body and the only legal way for transmigrators to integrate into society.

Outside the court, two external forces also exert a huge influence.
The Four Seas Merchant Association, formed by early transmigrators and local merchants, controls glass, happy water, compressed biscuits, and other otherworldly goods, monopolizing the market and amassing immense wealth. It is a paradise for profit-seekers and a hotbed of conspiracies.
The Pure Stream Academy, led by local Confucian scholars, symbolizes the guardian of traditional culture. Academy disciples recite classics, emphasize the teachings of their masters and rituals, and are wary of otherworldly ideas, preferring to limit them through debate and education, never resorting to force.

In the capital, bustling activity and solemnity coexist.
In the red-light district, information and entertainment are equally valued.
In the South Wind Pavilion, scholars and celebrities, under the guise of elegance, are equally addicted to desire.
The East Market of the capital is bustling with people, a gathering place for information and rare goods.
The Pure Stream Academy resounds with the sound of reading, and the debate grounds are filled with the clash of new and old ideas.
And in the Soul Purification Bureau, the suppressed archives and training grounds remind people that this is also a place of supervision.
The Four Seas Merchant Association's warehouses are filled with otherworldly goods, and luxury and novelty shock everyone's eyes.
The square in front of the imperial city, where the people often gather to witness ceremonies and executions.
The deepest part of the imperial city is the residence of the emperor and empress and the source of government decrees, solemn and majestic, not to be trespassed.

In this world, transmigrators may be placed as ordinary people, or they may become tools of the merchant association, objects of debate in the academy, or even secret agents of the dynasty.
You must choose: obey the registration system and integrate into society, or conceal your tracks and become an anonymous black户?
Will you throw yourself into the profit-seeking game, or enter the cultural arena?
Or, will you witness the tremors of history between the square and the imperial city?

This is the Great Yin—a stage both ancient and novel, waiting for you to write your own chapter.
