Abyssal Invasion? As a Demon Cultivator, I Laughed

In 2028, the Abyssal invasion brought supernatural powers to Earth, thrusting the planet into an era of global awakening. Humanity can now enter the Abyss to retrieve lost sparks of civilization and wield earth-shattering power, but the world remains under constant threat from terrifying abyssal entities. After transmigrating and inheriting the profound teachings of the Boundless Holy Path Sect, Chu Xiu stares deeply at a collection of utterly unhinged demonic secret arts. Crafting a Bone Banner, for instance, normally requires the sacrifice of hundreds of mortals—but surely, zombies count as people, right? He soon discovers that these grotesque and terrifying abyssal creatures are not only surprisingly effective for forging demonic artifacts, but using them generates zero karmic burden. Best of all, their numbers are practically limitless. Armed with this infinite resource, Chu Xiu begins to forge legendary demonic treasures and master forbidden divine powers that no one has ever achieved before: Blood God Banners, Profound Yin Corpse Kings, Heavenly Demon Avatars, and the Great Yin-Sha Formation of the Eight Desolations. Years later, as the Abyss launches a full-scale invasion and ancient deities sleeping for millennia finally open their eyes to gaze upon the mortal realm from the depths of the abyss, they find a single human staring right back at them with sparkling eyes: "Look at those thick tentacles! Those gorgeous eyeballs! What an absolute treasure trove of prime crafting materials!"
