Lu Yuning was a thirty-five-year-old office worker in the twenty-third century who died from overwork and arrived in the Underworld. With no family to burn offerings for her, she spent three hundred years working menial jobs while studying for the highly competitive recruitment exams of the Heavenly Court. After finally passing the assessments, she discovered that the Quick Transmigration Department was full. Instead, she was accepted into the newly established System Department, a bureaucratic branch responsible for supervising task employees in mission worlds. Following a grueling pre-employment training period, she was paired with System 009, a low-intelligence virtual assistant, and assigned her first mission: the Era Cannon Fodder Series.
Lu Yuning drew a lottery ticket for a mission titled "The Cannon Fodder in a Fortune Child Story." She entered a mission pod and transmigrated into a Small Thousand World based on a popular era novel set in 1960s China. She became the five-year-old Lu Yuning, the youngest daughter of the third branch of the Lu family in Hong’an Brigade. In the original novel, the female lead was Lu Yuxin, known as Fubao, the treasured lucky child of the neighboring Ninth Branch. The original host of Lu Yuning’s body was defined as the unlucky counterpart who lived in the shadow of Fubao’s protagonist halo, envying her privileged life until she died an ordinary, regretful death. Lu Yuning’s mission objective was simple: live out her natural lifespan and become the protagonist of her own life.
Upon arrival, Lu Yuning observed the stark contrast between her family and the Ninth Branch. The Lu family was large, poor, and hardworking, with every member contributing labor to survive. In contrast, Fubao was spoiled rotten by her grandparents and cousins, never required to work, and constantly showered with snacks sent by her army cousin. The original host had spent her childhood envying Fubao, believing her own life was miserable by comparison. Lu Yuning, however, maintained a pragmatic adult perspective. She recognized that her family, despite their poverty, provided genuine care, stability, and mutual support. She found satisfaction in small pleasures, such as the sugar rice cakes her grandmother made, and took pride in her own ability to earn work points by cutting pig grass.
The core conflict emerged through a dispute between children in the brigade. Fubao’s cousins, Lu Shier and Lu Shisan, manipulated a boy named Lu Yushan from the Third Branch by promising him biscuits in exchange for cutting pig grass, only to renege on the deal. When Lu Yushan confronted them, Lu Shier attacked him with a rock, causing a severe head injury. The incident escalated into a public confrontation between the families, drawing in the brigade leader and production team head. Lu Yuning watched as the adults argued over the truth, work points, and family honor. She realized that the original host’s fate was not predetermined by fate alone but was shaped by her own choices and associations. By distancing herself from Fubao and focusing on her studies and family duties, Lu Yuning began to carve a different path. She avoided the negative consequences that typically befell those who stayed close to the female lead, proving that she could escape the role of cannon fodder through observation, caution, and independent effort.
