When Earth's magnetic poles vanished in 2020, cosmic radiation nearly annihilated humanity. Over the following century, creatures underwent radical mutation while the surviving human population—reduced to tens of thousands—endured in fortified bases. In the Abyss, among mutated xenogenics, exists An Zhe: a sentient mushroom who assumed human form after consuming the remains of deceased human An Ze. Driven by singular purpose, An Zhe infiltrates the human settlement to retrieve his harvested spore. There he confronts constant danger—discovery guarantees death. The Judges patrol relentlessly, tasked with identifying and eliminating all xenogenic lifeforms. Colonel Lu Feng leads them with unmatched perception and ruthlessness, executing any confirmed xenogenic immediately. Yet An Zhe's true nature remains imperceptible to Lu Feng's discerning gaze, weaving a complex story where human and xenogenic worlds collide and intertwine. Silver Award winner at the 12th Chinese Nebula Awards for Chinese Science Fiction.
