Introduction to the work of "Blade Peasant Girl" Lin Wanxing, the top agent of the 21st century, was betrayed by his teammates during a mission. After falling off a cliff, he traveled to Baijia Village in the ancient Qin Kingdom and became a 12-year-old peasant girl with the same name. When you open your eyes, you will see a desperate situation: the family has only four walls, and the only mud house is leaky; father Lin Jianjun fell off a cliff half a year ago and is paralyzed in bed, suffering from bedsores every day; eight-year-old sister Lin Xiaoyue is sensible and precocious, but has a sallow complexion due to long-term hunger; six-year-old brother Lin Chaoyang is so hungry that he faints and his life hangs on a thread. What's worse is that Zhao Cuihua and Er Bolin Jianye, the grandmothers of the old house, regard them as a thorn in their side. They take advantage of the situation to rob food and property, beat and scold them at every turn, and take the suffering of the third family as their own pleasure. With the calmness and wisdom of an agent, Lin Wanxing rolled up her sleeves and shouldered the heavy burden: during the day, she went up the mountain to dig herbs, set traps to catch hares and pheasants, and used her medical and poison knowledge to treat her father's bed sores; at night, she set up animal traps to prevent sneak attacks by her best relatives, and secretly planned her livelihood. Faced with Zhao Cuihua's behavior and Lin Jianye's greed, she no longer swallowed her anger like the original owner, but used strategies to fight back, making her best relatives suffer so much that they never dared to come to her again. Aunt Sun's tortillas, Aunt Zhou's salt, Zhang Tan's free leather tanning, Uncle Li's forest guidance... The kindness of the neighbors gave her warmth, and she also used her own abilities to repay her: helping Uncle Sun cure his cough, sharing herbal knowledge with the villagers, and relying on Tianxianglou's stable sales of game for food and cloth. From providing food and clothing to saving money to buy land to grow food, from mending old clothes to making new clothes for the family, Lin Wanxing relied on the survival skills of an agent and modern thinking to lead his family out of the quagmire step by step.
