Lu Jie is a man of science reborn into a world of scheming sects and arrogant cultivators who prize raw power over reason. Rather than chase the immortal heavens through brute cultivation, he turns to alchemy and rigorous scientific inquiry to uncover the underlying laws governing qi. Starting from the very bottom rung of a sect hierarchy, he carves out a unique path no cultivator has ever walked before.

Lu Jie is warm, relentlessly curious, and self-aware enough to laugh at the genre tropes he keeps tripping over. His scientific mindset makes him distinct from the typical 'chosen one' cultivator, and his genuine care for the large cast of companions around him — human and spirit beast alike — gives the series its emotional core. He grows in power steadily, but never loses his essential humility.

Across five books, Lu Jie grows from a curious sect outsider into the de facto savior of an entire empire, accumulating spirit beast companions, founding his own sect, navigating court politics, and ultimately confronting a world-ending Demon God. The series balances slice-of-life warmth and found-family bonds with escalating cosmic threats, culminating in a bittersweet but satisfying ending that pays off five books of careful setup.
