A modern person transmigrates into the timeline of the Great Tribulation of the Demonic Dao, becoming a Nine-Leaf Sword Grass growing on Mount Buzhou. By chance, he obtains the inheritance of the mighty Pangu! He exposes Hongjun's schemes, helps Nuwa create humanity and develops a martial path suited to humans. He helps Houtu awaken the Earthly Dao, stops Hongyun from giving up the Primordial Purple Qi, and prevents the Great Tribulation of the Witch and Demon clans from happening! He awakens both the Human Dao and the Earthly Dao.
When Chaos first emerged, the primordial world was far from peaceful. Flames of the Great Tribulation of the Demonic Dao swept across the land. The Demon Ancestor Luohu tempered the Immortal-Slaying Sword Formation with the essence and blood of the three clans. Its killing aura soared to the heavens, plunging the world into darkness and laying waste to all living things.
Atop Mount Buzhou, in a crack in the stone cliff of the pillar that held up heaven and earth, a Nine-Leaf Sword Grass quietly took root. Its long, narrow leaves shone with a faint green-gold gleam. At its heart was a soul from the modern world.
Three days ago, he had been an overworked wage slave staying up late to write. When he opened his eyes, he had become this primordial spirit herb. The memories of the primordial world flooding his mind sent a chill through him. After the Great Tribulation of the Demonic Dao would come Hongjun merging with the Dao, the war between the Witch and Demon clans, humanity struggling to survive between them, and one immeasurable tribulation after another. All living beings were merely pieces on the Heavenly Dao's board.
