I Am an Evil God in the Library

Lucifer, the Supreme Lord of the Demon World, couldn't bear the day and night government affairs, so he disguised himself as a waste with zero magic power and went to work as a librarian at the worst magic academy in mankind. He just wants to drink tea and read human novels. In the college, a common female student often brought him desserts, which made him very comfortable. Until the college was invaded by a powerful enemy, the dean and the elite students were all defeated, and the female student was also seriously injured. The enemy leader clamored for a bloodbath in the academy. When everyone was in despair, Lucifer smacked his lips helplessly, put down the tea cup, and picked up a crushed wand from the ground. He stepped forward, and the terrifying magic power caused the space to begin to shatter. He looked at the enemy with eyes like a group of noisy insects: "Do you know that making a retired veteran cadre angry... The consequences will be really serious."
