Jason Lawrence, whose work is to restore ancient books, had always longed to escape his family's constraints and live a peaceful life, until his sister Lily suddenly contracted a mysterious illness that clan members called the "ancestral curse." When family members began falling ill one after another, while current family head Victor somehow always miraculously provided an "antidote," Jason began to suspect a dark secret lurking behind these events. Following a hint from his mentor, Walter Thompson, at the library, Jason returned to the abandoned family home and accidentally discovered encrypted notes left by his grandfather, Franklin Lawrence. The deciphered contents hit him like a thunderbolt—the ancestral burial ground that the family had protected for generations wasn't a blessed site, but a massive ancient tomb filled with deadly traps. The so-called "curse" was actually Victor using a sound wave device from the tomb to systematically eliminate pure-blooded family members who threatened his position. Even more heartbreaking for Jason was learning that his father, Gregory, who had "disappeared" ten years ago, had actually died in the tomb while searching for the truth. To save his sister and innocent family members, Jason formed a "truth-seeking team" with his childhood friend Leo Lawrence and tech expert Michael Carter. On a stormy night, they infiltrated the ancestral tomb that had devoured countless lives. They not only had to solve deadly puzzles like the "Corridor of Three Questions" and the "Court of Stars"—ancient wisdom combined with modern technology—but also engage in a desperate life-or-death chase with Victor's pursuers along the "Path of Heartlessness." Deep in the burial chamber, Jason finally found his father's remains and a tear-stained final letter, revealing a truth more brutal than he could have imagined. In the final "Return to Origin" ritual, he used the mechanism his grandfather had left behind to turn the tables on Victor, using the "Soul-Devouring Sound" to make the hypocritical family head fall victim to his own trap. However, when Jason became the new family head as a hero, vowing to establish a democratic and transparent new Lawrence Family, time proved a cruel truth—the dragon-slaying youth eventually became a dragon himself, just in a more concealed and deadly way. Ten years later, Jason hadn't become Victor; he had become something far more terrifying.
