Lu Chen, an ordinary college student working late into his thesis, was sent into the world of "Mortals" by a "kind" punch from the Dirt Truck Emperor. His soul then possessed the body of a hapless, third-level Qi Refining cultivator of the same name and surname, a mere handful of spirit stones, on an unnamed island in the Broken Star Sea. Faced with the predatory nature of the immortal world and its constant dangers, Lu Chen was overcome with grief: "I just want to find a job after graduation!"

Relying on vague fragments of his memories of the original novel and the logical thinking of a modern engineer, he cautiously struggled to survive in this unfamiliar sea. He started out by reselling low-level monster materials, then used modern knowledge to refine low-level alchemy formulas; from fleeing in panic from small-time forces, he carved out a niche for himself on an unnamed island, using a crude formation. He had no idea he'd arrived thirty years too early, or that the future "Han Paopao," who would become a worldly legend, was still ignorant and naive in a mountain village somewhere in the southern sky.

Thirty years later, when Lu Chen, reaching the late stage of Foundation Establishment cultivation and armed with several ancient treasures and secret techniques found in the Broken Star Sea, embarked on a ship returning to his homeland in the Southern Sky, fate quietly shifted. He would join the Yellow Wind Valley as "Senior Brother Lu," and befriend the cautious, steady-minded young man, Han Li. Their fateful encounter forged a friendship that served as both mentor and friend. Through foresight and dedicated effort, Lu Chen surpassed Han Li in achieving Dan, Nascent Soul, and Spiritual Transformation... his cultivation remaining a full half-body lead.
