Slay the Gods: Golden Core Martial Artist, Slaying Susanoo from the Start

In the world of The Bad Kids, he gains three hundred years of cultivation from the Bad Marshal, reaching a power that seems to touch the heavens. In the Twelve Valleys, his mastery of Gu techniques is enough to shame the twelve valley masters. In The Outcast, he faces the entire world of outcasts alone with nothing but his sword, seizes countless treasures and cultivation techniques, forms a golden core, survives the immortal tribulation, and enters the realm of immortals. In a mist-shrouded world, he delights in slaughtering gods and uses their corpses to nurture Gu insects. He is a god-slayer feared by all the deities. I'm no good at writing introductions, so please head straight to the story.
