A "Newcomer's Adventure" in a vaccine production workshop, under the cold shell of steel, data and rules, witnesses the dual tempering of technology and human nature. Zhou Qiming, a master's student, stepped into the majestic and clean vaccine factory with ideals in mind. He soon discovered that this place was not the high-tech paradise he imagined, but a sophisticated world composed of giant steel tanks, countless SOPs (standard operating procedures) and thick records. Here, every parameter and every signature is related to human life, and a 0.1% Deviation may mean millions of losses and risks of life. Starting from clumsily wearing three-layer clean clothes, Zhou Qiming, under the leadership of strict tutors, calm and unkind QA (quality assurance) monitors, and colleagues with different personalities, experienced night shift shocks, provincial inspection storms, and the setbacks and successes of process transfers. At the same time, dangerous municipal construction outside the wall, malicious threats from the dark, and an office romance quietly growing on the edge of the rules have all made his growth path full of thorns. When external crises and internal risks erupt at the same time, Zhou Qiming and his colleagues must work together to protect not only the hope of the vaccine bred in the can, but also the dignity of the profession, the weight of life, and the warmth of humanity that still beats under the cold data.
