After Ten Years of Failure, I Discovered That It Was a World of Demons

Jiang Bai was reborn in ancient times. He studied hard for ten years and failed miserably. When I returned home, I accidentally discovered that my sister-in-law was a fox demon, and then I realized the world of demons I was in! At the same time, Jiang Bai awakened the most powerful upgrade system! "Congratulations to the host for successfully killing a first-grade demon. The reward: the Confucian and Taoist Holy Body!" "Congratulations to the host for successfully killing the third-grade banshee. Reward: Follow your words!" During the day, Jiang Bai was a weak scholar who had no strength and only wanted to take the imperial examination. At night, Jiang Bai transformed into a Confucian and Taoist fanatic, killing demons everywhere! Looking at the nine-tailed demon fox queen who was kneeling on the ground and shivering, Jiang Bai said in a deep voice: "Put your hair up! Do you hear me? I asked you to put your hair up!"
