Wuxia Crossover: From the Start, Six Sects Surrounded Me, So I Cut Through Them All

I transmigrated and nearly starved to death before an old man named Dong Tianbao rescued me. Five years later, my master died. Carrying his ashes, I set off for Wudang as he had wished. But from the start, I was thrown into hell difficulty: the Six Great Sects were attacking Wudang Mountain, and dozens of martial arts experts were forcing Zhang Cuishan to his death and even trying to kill Zhang Wuji! These so-called orthodox sects are worse than the Demon Cult! At this critical moment, the System, five years late, finally came online! 【Strong emotions detected in Host. Heaven's Justice Punishment System activated!】 【Newbie gift pack: Indestructible Vajra Art, perfected!】 In an instant, blades and bullets couldn't hurt me, and fire and water couldn't harm me. My defense was maxed out! What are we waiting for? Let's do this! You want to hurt Zhang Wuji? I'll show you what it means when “your attacks do nothing to me, and my counterattacks will end you”! A Kongtong elder? Taken down in one move! The Kunlun sect leader? Crippled with one punch! The Six Great Sects' masters are like a bunch of three-year-olds in front of me! Abbess Miejue: “Boy, who exactly are you?” I point to the urn on the ground. “He's my master, the ‘traitor’ you all talk about. And I'm here to clean house, and while I'm at it... clean up the trash you call the martial world!” Saving Zhang Cuishan was just a side benefit. My real purpose is to place my master's ashes in front of Zhang Sanfeng with my head held high! Then I'll tell him that the man he misjudged all those years ago raised a disciple who can sweep through the entire martial world! The Heaven Reliant Sword? The Dragon Slaying Saber? The Nine Yang Manual? Sorry, I'm taking them all! The martial world is too murky, and it's full of hypocrites. Let this “villain” carve out a clean world with his own hands!
