My Cultivation Is A Legendary Dagger

Zhao Cheng transmigrated, only to find himself the infamous 'Jade Rat,' a legendary thief, now battered, bloodied, and condemned to death row. Framed for stealing the mystical 'Thousand Miles of Rivers and Mountains' and crippled by a ruthless princess who destroyed his cultivation, he was left as mere bait for a terrifying assassin. His modern knowledge was useless; his life was forfeit. But in his darkest hour, a miracle: the 'lost' legendary dagger, Madam Xu, wasn't destroyed. It had fused with his ruined Qi Sea, rebuilding his core stronger than ever. This sentient blade became his very cultivation, granting him unparalleled stealth, combat prowess, and the hidden memories of the thief saint. He was no longer just a man—he was the living blade. With the assassin dead by his newfound power and a new identity forged, Zhao Cheng, now Zhao Yushu, prepares to disappear into the city's underbelly. The Princess thinks him dead, the Man in Black's patrons remain hidden, and an entire empire unknowingly stands on the precipice of his vengeance. But how will he, a crippled thief, truly exact revenge on those who control the very capital?
