Arthur McConaughey is the most inconspicuous plumber in Harbor City—and the despised "live-in son-in-law" of the Black family.
Three years ago, he entered into a marriage contract with the Black family, a union that everyone deemed far beneath Emily Black.
But at a charity gala, a bodyguard for the powerful Klaus family saluted him in public, addressing him as "Dragon Lord." Slowly, the layers of his true identity began to peel away.
Facing a relentless onslaught—the financial strangulation by the Klaus family, forced demolitions by Green Real Estate, a total blackout by the New York elite, and a hostile power grab from the McConaughey clan—Arthur navigates every challenge with calculated precision. Meanwhile, his wife, Emily, evolves from a woman full of doubt into his most trusted partner, growing from someone in need of protection into an equal who stands firmly by his side. As the truth behind "Project Zero" finally surfaces, Arthur discovers that the secret his parents gave their lives to seal away lies hidden deep within the heart of the Arcadia Museum.
