Beginning Longevity by Refining Demon Qi

【Steadfast and fearless, ruthless and decisive, transmigration】 Lin Huai transmigrates into the weakest demon in the world. Killing other demon beasts earns him demonic energy. Refining it lets him develop new demon arts, and growing stronger is just a thought away. In an instant, he rises from a lowly little demon into a mighty one who inspires awe and terror, and keeps growing stronger at a staggering pace. In a troubled age, demons run rampant, ghosts multiply, and people's hearts are shrouded in darkness. He stays true to himself, slaying the demons that deserve to die and vanquishing the monsters that wreak havoc in the world. Until he catches the faint, elusive scent of immortality in the world. He develops demonic arts amid clashing thunder. He comprehends the Dao beneath the bright moon. He envies the mandarin ducks by the peach-blossom spring. And in an unexpected place, he finds immortality.
