Doomsday: I've Evolved My RV into a Cosmic Ship

When the doomsday came, the city turned into ruins, and the earth turned into a slaughterhouse!
Zombies roared in the ruins, treating living people as food.
Mutants became rampant in the darkness, taking pleasure in torturing and killing living people.
Tom had the chariot system after he was reborn. He could strengthen the chariot infinitely by killing the zombie!
Everyone else fled in a hurry at the end of the day, while Tom looked at the group of zombies that were fleeing and shouted excitedly, "No one can escape!"
Every shelter: "It's not a car at all. It's a mobile fortress. The shelter we built is as fragile as paper compared to Tom's chariot!"
Every research organization: "How could it be possible? How could Tom's technology be so powerful? It's just magic!"
Evolved man: "If we are extraordinary professionals, then Tom is the god!"
Junkman: "I want to go to Tom's shelter. It's the safest place in the world!"
