Yin Wanxing, a 27-year-old hotel receptionist, was betrayed by his fiancé and his best friend in his previous life and died of bloodletting. He died with the hotel. Thirty days before she was reborn in the apocalypse, she unexpectedly awakened [the apocalyptic hotel management system] and used all her savings to buy a run-down hotel in the suburbs, becoming the only "safe house" owner in the apocalypse. She looks like a soft-spoken girl who speaks slowly, but in reality she acts as a protector, luring her enemies into the hotel and then throwing them out to feed the zombies. The hotel only charges a life-threatening "room fee" - materials, intelligence, and even marrow crystals. Here, staying is a gamble for your life, and the blacklist is a reminder of your life. When the bloody defected researcher Lu Siyan came to her door with a golden marrow crystal, and when the military, laboratories, and doomsday organizations all coveted her hotel, Lin Wanxing held the system in hand and slowly wrote on the check-in book: "Welcome. I wish you... A pleasant stay."
