I Slayed Demons in the Tang Dynasty and Attained Enlightenment

Gu Changan, who traveled through time and became a bad guy in the Tang Dynasty, awakened the Golden Finger of the Demon Refining Furnace. I originally thought that I would be able to level up from slaying demons and rise to the top, but I didn't expect that I would encounter a nine-tailed fox demon on my first mission. The fox demon smiled sweetly: "Little Master, your stove... Seems like it can't shut me down." The next second, the demon refining furnace shook violently, and Gu Changan's expression changed drastically—— This stove looks like it's going to explode!
