Su Wan, a gifted young woman who dropped out of junior high school, makes a living working as a night-shift cleaner. By chance, she solves a seemingly impossible twin-tower structural load problem that has baffled the architectural community for three years. However, the credit is stolen by the wealthy Xu Jiao. After publicly exposing the fraud, Su Wan rises to prominence, breaks free from her exploitative birth family, and joins forces with Shen Yan, a once-renowned architect who has retired from the industry, to expose the dark secrets behind the construction sector. Ultimately, she achieves unanimous acclaim at an international architectural competition, and the two find redemption in each other as they become legends in the industry.
