From the Start, I Had a Hundred Billion Years of Cultivation

[At least three chapters a day, so read with confidence!] A peerless demonic sword kills its master, seizes his body, and is reborn with a hundred billion years of cultivation. It traverses the ancient forbidden zones and sweeps across the Eight Wilds and Four Seas! With a snap of its fingers, the realms of the gods crumble into dust! It breaks through every shackle and overthrows the immortal sects founded by emperors! In this life, it will become the strongest being, reigning over the Nine Heavens and Ten Lands!
