Escort Bureau Assistant: Broken Jade Connects Earth Veins

Twelve years ago, the North Territory broke out and the entire camp turned into a purgatory. The five-year-old boy was dug out from the pile of corpses, holding a piece of jade tightly in his hand. No one knew where he came from, and no one cared. The escort agency took him in, gave him food, and worked as an animal for twelve years. No name. No origin. Only the piece of jade on the chest that is getting smaller and smaller has never had any heat in twelve years. Until the night when the batch of black stone darts arrived—— The jade is hot. Something was waiting for him deep underground.
