The modern explorer Shen Wan traveled through time and became the legitimate daughter of the Zuo Xiang who was expelled from the Daqian Dynasty. On the third day of her wedding, she embarked on a three-thousand-mile exile with Xiao Jingheng, the crippled king. In a critical moment, she activated the Doomsday Fortress All-in-one RV system, disguised a heavy-duty off-road RV as a dilapidated carriage, and used bulletproof body, constant temperature air conditioning, modern medical treatment and weapons arsenal to carve out a way out of the desperate situation. On the way to exile, Shen Wan used high-voltage electric shock batons, drones and other magic weapons of the Immortal family to reduce the dimensionality of his attacks, and successively resolved oppression by officials, heavy rains and mudslides, night attacks by wolves, miasma in the black forest, sieges by bandits, and multiple batches of killers sent by the emperor.
