Yu Nian'an was reborn in the apocalypse.
In his previous life, he watched everything fall into ruin with his own eyes, ending in tragedy. When he awoke again, the butterfly effect had quietly rewritten the entire timeline, bringing together many people who should never have met.
High walls separated the ruins from the survivors, while the base within struggled to endure. Aberrants rampaged, a mother organism lurked in the shadows, and danger drew closer with every passing moment.
In this life, he didn’t seek to save the whole world. He only wanted to give everything he had to protect the people he cherished.
Brutal survival, comrades fighting side by side, memories of his past life buried deep within... step by step, he moved toward the truth, and toward a fate already written.
