My System Said \"Be a Passerby\"... I Built an Empire.

Forced into the lowest tier \"Passerby A System,\" Shi Yan is dumped into a dying empire's cold palace as a sickly three-year-old prince, destined for oblivion. His mission: remain hidden, \"grow vulgarly,\" and passively witness the fated protagonists become a \"grudge couple.\" But Shi Yan refuses to be a plot device. Armed with a sharp intellect and a quirky system companion, he unearths forgotten secrets and leverages hidden connections. From barren rags, he conjures bountiful riches—recruiting gourmet chefs, master tailors, erudite tutors, and skilled craftsmen. His desolate prison transforms into a self-sufficient, luxurious haven, utterly detached from the unfolding chaos. As the \"heroes\" stumble through their fated, yet subtly twisted, romance, Shi Yan, from his secret throne, silently pulls the strings. His comfortable life is secured, but is this quiet luxury his final ambition, or merely the prelude to an even grander, unseen rise?"
