15 years of failure. 3 months until exile. 1 million buckets of water... and the System finally awakens. Aurelian Chu transmigrated to a ruthless world of immortal cultivators with one massive a Defective Spirit Root. Stuck as a lowly menial servant in the Cloudspire Sect, he's spent fifteen grueling years watering medicinal herbs just to survive. At thirty, he faces mandatory expulsion. His cultivation path is officially dead. Or so he thought. When Aurelian hauls his one-millionth bucket of water, he unlocks the Heavenly Dao of Diligence System . No overpowered legendary artifacts. No sudden cheat bloodlines. Just a simple, unbreakable Consistent effort guarantees measurable progress. Every bucket carried increases his Constitution. Every herb chopped boosts his Spirit. Every beginner manual read levels up his Fire Control. Transferred to the prestigious but deadly Alchemy Hall as a pawn in a bitter sect rivalry, Aurelian is surrounded by arrogant prodigies and ruthless masters who see him as stepping stone. But they don't know his secret. While they spend decades meditating for a sliver of enlightenment, Aurelian is quietly grinding his stats, leveling his skills, and preparing to break every rule of cultivation. He might have started at the absolute bottom, but with enough hard work, even the heavens will have to make way.

Aurelian has inherited the Astral Zenith Sect, becoming its new Sect Master and claiming sole control over its secret realm. Armed with ancient cultivation techniques and vast resources, his strength continues to shatter past limits. But the dangers outside the realm are rapidly escalating, and a far deadlier threat has just surfaced: the Heavenly Demon Sect has laid an ambush in Greenwood Valley, trapping his sister, Seraphina, in a sinister blood ritual. With hostile factions and rival cultivators closing in, Aurelian cannot afford to let his guard down. To survive these mounting threats and protect his family, he has no choice but to master his newfound abilities and relentlessly expand his power.

Turning the tables on an Archdemon inside a lethal blood array was only the beginning. With his enemy's cultivation devoured and his clan safely relocated, Aurelian claims a coveted invitation to the Eastern Region's deadliest proving ground—the Genius Tournament. Cloudrest Province is nothing like the Azure backwater he came from. Here, prodigies are common as dust, and a single glance at his Defective Spirit Root is enough to write him off. Let them. The Five Great Geniuses sit at the top of this region, and Aurelian intends to climb over every one of them. At the summit of the hundred-step Trial Stairway lies the legacy of Sovereign Lin—an ascended immortal whose power has gone unclaimed for ten thousand years.
