Some gates are not meant to be opened. Some frequencies were never meant to be heard.Deep in the mist-soaked mountains of Guizhou lies Yinyu Village, a place erased from maps and memory. When a research team arrives to test the next-generation AR device-the Iris-4-they expect silence.Instead, they awaken the dead.Elias Thorne, the brilliant architect behind the Iris-4, soon discovers that the valley is not a blank-signal zone but a sealed spiritual containment field. The village is a lid, built generation after generation to trap something older than dynasties.But when the Iris-4 activates, the seal cracks.In the ghost-infested Yin-side of Yinyu, green funeral lanterns rise. Doors of empty homes slide open. Footsteps circle the ancestral hall. And the river-black, silent, and ancient-begins to wake.What the team believed was topographic interference becomes horrifying truth: the AR device is not mapping the spirits-it's letting them through.Now trapped overnight on the forbidden side of the river, Elias and his team must confront the truth buried beneath the village, decode the ancestral warnings, and survive the night-long siege of Jiuyou-the deepest underworld of Chinese myth.Terrifying, immersive, and fueled by folklore and cutting-edge tech, Spirits of China blends cosmic horror with ancient ritual in a relentless descent into the unseen.Once the Iris-4 opens its eye... the spirits never close theirs.
