Lu Chenzhou, a young servant at Hidden Sword Manor, bears the Great Dao of Ten Thousand Swords Returning to the Hidden Treasury, yet possesses no spiritual power for cultivating immortality. He spends his days buried in the task of organizing sword manuals and is regarded by the world as a useless nobody. At the grand gathering to appraise famous swords from across the heavens, the prodigy Sima Duankong flaunts his power and attempts to destroy the Scripture Pavilion. At the critical moment, a single drop of ink from Lu Chenzhou dispels peerless sword energy, and a single remark exposes the flaws in the sword techniques of every sect, causing all the famous swords present to bow in worship. From a mere young servant, he ultimately rises to become the Master of Ten Thousand Swords, whose name shakes the immortal realms.
