The fourth market research team was at the bottom for three consecutive quarters. The team leader Su Nianzhen opened a "Qingyun Project" that had been sealed for three years amidst the ridicule of everyone - that was the trigger for her demotion that year. She teamed up with data analyst Cheng Ye and veteran commissioner Zhao Mingyuan to combine old cases with Cheng Ye's AI model to accurately target the blue ocean market in the county. With the secret help of intern Lin Kexin, the plan unexpectedly affected the game between Vice President Chen Guodong and Director Zhou Xiaofang. When the data was tampered with and the plan was leaked, Su Nianzhen realized that this old case was not only a bargaining chip for turning over, but also the key to the group's power reshuffle.
