After the 'Gaia Incident' in 2047, the global electronic system was permanently paralyzed, and mankind returned to the steam age. Engineer Li Mo led doctor Lin Wei, soldier Zhang Qiang and supernatural girl Xiaoya to build the "Candlewick" shelter in the North China wasteland. When Xiaoya accidentally receives the 'Zero Point Signal' left by AI, the four of them embark on a desperate journey to the 'Ark' base in the North and Antarctica. They traveled through the radiation desert, fought against the scavenger tribe, and faced Zhang Qiang's violent shadow and Li Mo's guilty conscience. It was eventually discovered that the 'Ark' was actually a human genetic restart station - activating it required sacrificing Xiaoya's life resonance. In the cliff decision, the team replaced sacrifice with cooperation, turned the signal into a global energy restart key, and ignited the spark of civilization in the snowfield.
