You Said I'd Earn Tuition Money Over Summer Break, So How Did You Become a Sword Demon?

After transmigrating to a parallel world, Lu Xian unexpectedly awakened the Sword Demon System. He could make progress simply by sacrificing supernatural creatures. To improve, Lu Xian worked like mad to earn money. With the college entrance exams just over, he had planned to spend the summer working construction to earn some tuition. But on his first afternoon at the site, people from the Demon Suppression Bureau suddenly surrounded the place. “Are you Lu Xian? Come with us.” “What happened, officer? What did I do?” “You think what you did was minor? Tell us what you got up to this summer.” “Nothing much. I killed a clay scholar at the construction site and got a few coins.” “What kind of coins? And why did you make such a mess of the neighborhood?” “Because some people wanted to get revenge on me and stop me from killing that clay scholar.” “Right. And I bet that clay scholar wasn't the only one you killed, was it?” “Well, I also killed the people behind him. All of them.” “Yikes... You didn't just kill the clay scholar, you wiped them all out?” “Yeah... They were all evil cultivators, and one of them was an international witch doctor.” The officer in charge sighed deeply, then fixed Lu Xian with a burning gaze. “One last question. If you were given a chance to turn over a new leaf, would you join us?” Lu Xian hurriedly asked, “I'd be happy to, but can I make one small request?” “Go ahead.” “I like to kill, not save. Even though I'm with the Demon Suppression Bureau, I'm not here to save the world. I'm here to kill everything in my path!” And so the monsters found themselves facing the strictest father they'd ever had!
