War Truck in the Apocalypse

“The apocalypse is about to arrive! I have to survive!”
Shen Cong, a victim of persecution complex, saw someone mention online that the apocalypse was right around the corner, and he immediately believed in that person’s words. He hid himself at home and refused to go out, focusing on just creating his very own apocalyptic war truck and polish his survival skills.
And one day, six years later…
…The apocalypse arrived.
