When the "Eternal Night Sky" swallowed the sun without warning, the world instantly fell into biting cold and boundless darkness. The deadly "light-eating moss" spreads like a plague, devouring all light sources and heat, and human civilization collapses in despair. The survivors huddled next to the weak light. Every breath was precious, and every time they went out could be a farewell. Lin Jin, a "waste" abandoned by the times, awakened the strange "Eye of the Candle Dragon" in this catastrophe - his left eye can instantly dismantle any material and see its most primitive structure and energy flow! He can see through the failing core of the last energy battery that others regard as a treasure; he can instantly decompose the spoiled components of the can that others are fighting for; even facing the ferocious mutated "shadow beast", he can accurately find the fatal weakness of its energy core! However, these eyes were also a reminder of his life. Every time he used them, they crazily devoured his little life force. Does it bring hope to the protagonist or another crisis?
