In her past life, Shen Zhixia handed over her last box of rations, only to be locked outside and frozen to death. Reborn ten days before the extreme cold arrives, she hoards grain, prepares water, changes the locks, and vows never to be a pushover again. Acquaintances want to stay for free, neighbors force her to donate her grain, and Zhao Jiancheng locks the life-saving grain everyone bought with their money into his private warehouse. "Everyone is about to starve to death, and you're still only looking out for yourself?" Shen Zhixia tightens the door chain: "My grain will not be taken for free! The grain you bought, go ask him for it!" This time, no one will be able to step on her to survive.
