A delayed delivery order leads him to drive through an abandoned tunnel, breaking into a dying border fortress. There, beacon fires have not yet extinguished, the granaries are empty, and the lives of seven thousand people hang by a thread. Starting from a bowl of Luosifen, he travels back and forth between different worlds, delivering food, medicine, and hope to distant places.

What people are truly waiting for is never a piece of cargo, but rather that in times of utter desperation, someone is still willing to walk through the long darkness and reach their side.
