The Eternal Return of Fire

On the day the earth was destroyed, Lin Shen sent the consciousness of 7.3 Billion human beings into the universe. As the designer of the Tinder Project, he was the last to upload himself. No one knows that deep in the core code of Ark, he left himself a line of instructions that only he can see. Ten thousand years later, there are only 305 spark capsules left. Some people survived by devouring their own kind in the darkness, some collapsed and fled in despair, and some stood in front of the fire cabin like a monument that would never fall. But Lin Shen was always awake. He was so sober that even he almost forgot whether that line of instruction was to survive or to hold on to something.
