Pan Gaofeng returns to the First Academy of Aerospace Science and Technology after completing his graduate studies, joining the elite team tasked with developing the Long March 5, a rocket that will define his nation's future in space exploration. As a young engineer surrounded by veterans and peers equally passionate about the mission, he discovers that building something revolutionary means enduring setbacks that shake confidence and test resolve. When a launch fails spectacularly, the project faces mounting pressure from skeptics who question whether success is even possible. Gaofeng must navigate the weight of national expectations, the frustration of technical obstacles that seem insurmountable, and his own doubts about whether he belongs among his more experienced colleagues. Through late nights in laboratories and tense moments in control rooms, he learns that progress isn't measured in single achievements but in the collective determination to rise after falling. This is a story about ordinary people pursuing an extraordinary goal, where personal growth and technological breakthrough become inseparable.
