Rebirth of the Nine Netherworld: Decide the World with a Sword and Reverse the World

In my previous life, I was recognized by the virtual game "Nine Nethers" as the best swordsman in the world! But I discovered the cruel truth behind the game, and was cruelly silenced by my most respected master, and died tragically with hatred. Once reborn, I returned to the eve of the launch of the server of "Nine Nethers"! With full level memory, peerless sword skills and all the secrets of my past life, I am back! In this life, I will never make the same mistakes again! The frail sister said: "Brother, there is medicine in Jiuyou that can cure me." The hypocritical and paranoid Master attempts to control all mankind and turns everyone into pawns. I hold a heavy knife in my hand, with murderous intent: Protection is never control! Kill the counterfeit master, solve the conspiracy, save your sister, and rewrite everyone's tragic ending! From a nobody in Jiuyou, he became the strongest swordsman who surpasses all living beings!
