The sun has been annihilated for hundreds of years, and humans have huddled in the fire of the earth to survive. Qin Jin, the abandoned son of the former stand-in, accidentally activated the twin system while digging for fire insects in the ice - the holy [Fire] wanted him to save the world, and the crazy [Breaking Oath] lured him to destruction.
In order to get a mouthful of food, he led his team to storm the frozen granary, but encountered the Bone Eater, who could tear apart armor, and the tribal chieftain Cao Man, who pursued the law of the jungle. When the Tinder system issued the mission of "rescuing young children" and the oath-breaking system showed the words "kill the chief" in blood, Qin Jin opened the trap with a grin: "I want them all."
The seed bank of ancient civilization deep in the granary reveals the truth that humans once actively extinguished the sun; the mother's nest brand on the tribal saint points to the awakening of supernatural powers from radiation experiments. The two opposing systems in Qin Jin's body are exactly the split good and evil personalities of the "Tinder Project" AI.
With his left hand he built a shelter to take in refugees, and with his right hand he held a knife to destroy his enemies, walking on the tightrope between order and chaos. When the wanderer and profiteer Liu Huaishan monopolizes day money and triggers a currency war, and when the world-destroying bloody feast predicted by the prophet Zhou Tong comes, Qin Jin plots a plan to massacre the rebels, but he discovers the Tinder logo with his childhood number engraved on the bottom of the celebration wine bottle.
In order to end the eternal night, he went deep into the alien nest to seize the core of the mother nest, and faced the confession of the scientist's consciousness: "We thought that creating a fire spring could replace the sun, but we released the devil in the center of the earth." Finally, standing in front of the artificial solar furnace, Qin Jin faced the ultimate choice: ignite the fire of civilization and sacrifice himself, or let mankind fall into darkness forever?
The only light in the eternal night is the embers of betrayal.
