When "rust fever" tears apart the veil of civilization, the world falls into disorderly carnival and wailing. Chen Mo, a former mechanical engineer, did not wait for the legendary perfect refuge. He only got a 30-square-meter abandoned tour bus parked in a suburban auto repair shop - leaking rain, power outage, and a half-dead engine. It was also full of dust and a scrawled note left by the previous owner: "It can take you anywhere, if you can repair it."
This is not a story about having an invincible fortress. This is a story about an ordinary person who uses wrenches, wires, broken glass and tenacious rationality to regain his living space inch by inch in a zombie-infested hell. When others looted, he repaired; when others hid, he calculated the inclination of solar panels; when others betrayed for a can of food, he tried to extract clean water from the rusted car wreckage.
From a leaky iron shell, to a mobile greenhouse, a silent stalker, a micro laboratory, and finally an ark carrying the fire of civilization. Chen Mo and his bus will travel not only through fallen cities and desolate wilderness, but also through the deep valleys of the collapse of human nature and the cliffs of technological ethics. What he has to face is not only the bloodthirsty "infected people", but also the more dangerous ghosts from the old era and the iron fists who are trying to establish a new order on the ruins.
Survival is not the goal, just the starting point. The real challenge is: after everything is destroyed, what do we leave behind and what do we rebuild?
The answer may lie in this 30 square meters of continuously extending steel space, following the wheel, heading towards an unknown tomorrow.
