When Bai Hanyun loses her family's favor following her grandfather's passing, she retreats to the countryside with nothing but a fresh start. Her modest country home conceals an extraordinary secret—an antique mirror dwelling in its basement that defies all logic. Through its mysterious surface, a connection forms between two worlds, and the consequences ripple across dimensions. Across the veil, General Feng Xiyan faces annihilation. Surrounded by the Yuezhi Tribe's forces and abandoned by the imperial court, he commands the desperate citizens of Xiqiang City as starvation and despair close in. Yet salvation arrives through impossible means—a divine intervention that transforms their fate. Supplies materialize without explanation, sustenance flows without source, and prosperity blooms where death once loomed inevitable. As miracles reshape their reality, neither Bai Hanyun nor Feng Xiyan can ignore the inexplicable bond drawing them together across the barrier between worlds.
