A lame boy accidentally activates an ancient immortal formation and is transported to another world. There he obtains the heaven-defying treasure, the Hunyuan Sumeru Gourd, but becomes trapped in the Space of Ten Thousand Laws. Chaotic spirit fiends and fiends of the Ten Thousand Laws bind him, rendering the treasure powerless. Yet he also acquires the ancient, heavenly-grade manual for cultivating as an immortal and a demon, The Immortal-Demon Method. To avoid calamity, the Dragon Ancestor transforms the immortal power and true qi within his body into a righteous, noble aura, which resembles chaotic turbid energy and is difficult to detect. He later becomes a disciple of the Red-Haired Ancestor, who is in fact the apprentice of the Blood Demon Ancestor, whose blood once flooded the world ten thousand years ago! By chance, he obtains the blood clan's sacred tome, The Blood God Scripture. From then on, he forges a path of cultivation that is neither demonic nor immortal.
