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 killed its master, seized his body, and was reborn with a hundred billion years of cultivation. It will traverse the ancient forbidden zones and sweep across the eight directions and four seas! With a snap of its fingers, the divine kingdoms will be reduced to ashes! It will break through every constraint and topple the immortal sects ruled by emperors! In this life, it will become the strongest being, ruling over the nine heavens and ten lands!
