Lu Yuan, a dedicated employee of eight years, is mercilessly laid off on the day his 4.8-billion-yuan project wins the bid, only to discover that the patent for his company's core technology has expired. Facing suppression by his former employer and an industry-wide blacklist, he rejects the temptation of a million-yuan renewal offer, takes the original patent documents, and partners with Ruicheng Group to establish Yuanheng Design Studio. With his formidable technical expertise, he secures contracts worth tens of billions, publicly defeats his rivals' slander at an industry association meeting, and pushes his former employer, whose shoddy construction practices come to light, into a shutdown crisis. Ultimately, he rises from a low-level engineer to an industry leader, achieving success in both his career and love life.
