Sword Immortal, Blade Demon, Abyssal Immortal Venerable

[No System] [Scheming] [One True Love] (This is a slow-burn story, with a lighthearted and comedic tone at first.) In the immortal lands of the Nine Provinces, countless cultivators have sought immortality, yet no one has ever truly ascended to become an immortal. Mo Yuan comes from Blue Star. At birth, a Yin-Yang millstone formed in his dantian, allowing him to cultivate immortal arts and demonic techniques alike. From then on, he embarks on an extraordinary path. Above the Heavenly Abyss, demons dance. Through the rise and fall of ages, he will become an Immortal Venerable!
