An Jing's advancement to the Purple Mansion, like every breakthrough in his past, was effortlessly simple, as easy as breathing.
The classics he acquired in the Tianyuan Realm, the secret transmissions he obtained from the Bright Mirror Sect, and the secret techniques and experiences he received from Jin Yanhua, Jiang Ziji, and other predecessors from various forces, all became the nourishment for his growth, turning into fragments of a vast puzzle.

When An Jing found a way to reconcile the Immortal and Martial paths, even though he hadn't found the final answer and the puzzle wasn't complete, the beginning was enough for him to prove his Void Purple Mansion.
