Chen Shang transmigrates into an apocalyptic world plunged into extreme cold, where he gains the ability to evolve infinitely. To escape the freezing waves, he binds himself to a secondhand van and heads south toward Sun City, humanity's last surviving refuge. Along the way, he encounters greedy relatives raiding supermarkets, neighbors occupying safe houses, malicious villagers, and cities blocking his path. Relying on his infinite evolution ability, Chen Shang repeatedly escapes danger as his van gradually evolves into an RV, an armored vehicle, and even a flying battleship. But when he finally reaches Sun City, he discovers that the greatest secret of the apocalypse is hidden there.
