Reborn as the Beloved Great-Aunt, I Feed the Whole Village Meat at Every Meal

When Chen Zhenzhu, a strength-type esper in the apocalypse, perishes alongside a Level Nine zombie, she thinks it's finally all over. But when she opens her eyes again, she's become a widow in ancient times. Her husband has died, and her in-laws have used an excuse to cast her out. After spending so long in the dark, merciless apocalypse, Chen Zhenzhu thinks: Better to live badly than die. Besides, the scenery in ancient times is lovely, and the plants and animals don't go crazy and eat people. With strength enough to move mountains, Chen Zhenzhu heads into the hills to hunt wild boars, then shares the meat with the whole village. She raises the piglets, rabbits, pheasants, and ducks she catches, and gets the entire village into livestock farming. With a library space she can carry around, Chen Zhenzhu uses the information inside to lead the villagers in raising livestock and growing crops. From then on, everyone in the village eats meat at every meal. [There is a male lead, but he appears fairly late.]
