Lin Xiaoman and Li Chang'an are a loving young couple who, after eating a meal of poisonous mushrooms, time-traveled straight into a primitive tribe. While other time-travelers face palace intrigue and power struggles, the two of them get a practical survival course in the wilderness—Lin Xiaoman has spent three years watching TikTok outdoor survival videos, and Li Chang'an is a programmer with maxed-out hands-on skills. Relying on identifying mushrooms, digging fiddlehead ferns, and harvesting chestnuts to save a starving tribe, they weave fish baskets to catch fish, make bows and arrows to hunt, and dig bamboo shoots and pick walnuts, leading a group of primitive people wearing animal skins to live a surprisingly flavorful life. Surviving while showering each other in sweetness, they reenact every day: "What should I do when my husband in the primitive tribe spoils me too much?"
