Reborn in a Creepy World, I Became a Dog

Zhang Heidi is reborn, but unfortunately, he becomes a dog. A cute little fox tags along, and he also obtains a jar from a three-eyed Daoist that can grant an unlimited number of wishes, though each wish comes at a price in the future. From then on, this dog slays demons, devours immortals, and destroys the paranormal. The protagonist is decisive and ruthless, never soft-hearted or sluggish. He gets revenge the same day, never letting a grudge linger overnight. (There’s a lengthy buildup at the beginning as the protagonist obtains the most important artifact, the Yin-Yang Demon Jar. The main storyline properly begins after the jar appears in Volume One.)
