A modern woman, Shen Wan, traveled to Daqian and became the legitimate daughter of the left prime minister who had her house confiscated and was exiled. She accidentally unlocked the doomsday RV system and disguised the RV as a coffin truck to travel with her. Her husband is Xiao Jingheng, the former god of war who was framed and lost his leg. On the way to exile, their eccentric father and mean stepmother constantly made things difficult for them, and the escorting officer also bullied them many times. Shen Wan relied on the modern supplies and electric shock equipment in the RV to fight back one by one. On the way, she dealt with crises such as heavy rains, plagues, wolf packs, and assassin ambush, and also rescued the suffering refugees. She used on-board medical equipment to treat Xiao Jingheng's injuries, and the two trusted each other in times of trouble. Shen Wan confessed the origin of time travel to Xiao Jingheng, and the two reached an agreement to cooperate.
