Are You from the Demon-Suppressing Division a Master of Heavenly Magic?

Xiao Xing traveled to the fantasy world of martial arts and became a member of the Demon Suppressor of the Dayu Dynasty. But what made Xiao Xing collapse was that he actually awakened the magic sacrifice system? What the hell? Damn it, don't play with me. I'm from the Demon Suppression Division. Why are you giving me magic powers? But suddenly one day, Xiao Xing was on a mission, and in desperation, he used the magic technique Xuanyin Finger to attack the people of the Xuanyin Sect! "Brother, stop fighting, we're on our own!" "One of our own?" Xiao Xing was stunned for a while, but when he turned around, Xiao Xing stabbed him in the head with a knife. He was heartbroken. The person in the demon sect didn't know why Xiao Xing wanted to kill one of his own until his death! From then on, Xiao Xing's world opened a new door. He transformed into Lao Liu, specializing in deceiving people in the demon sect and stabbing them when they were not prepared. It is not a meritorious deed! People in the demon sect are so frightened that they are being stabbed from behind, and they are about to collapse! Finally, the incident of the Xiao Guild's magic skills came to light! Xiao Xing: I study magic skills just to deal with them better! What? Do you want to punish me? Jie Jie Jie Jie, you seem to have forgotten, I am a demon cultivator, so don't blame me for being rude, I'm just waiting for you to use me...
