None of My Students Are Human

*This article is a fictitious world view and fictional subject matter, please do not substitute it. 1. After graduation, Ye Xuan successfully stayed in school as a counselor. On his first day of employment, he received a call from a student. The little girl was crying out of breath. She sobbed and said, "What should I do, teacher? I left my head at home!" Ye Xuan:...? Tell me again, what did you leave at home? 2. The first theme class meeting of the new semester starts with getting to know each other. Ye Xuan stood on the stage, looking at the group of strange students below, and fell silent. Finally, a young man who looked exactly like a human and looked very out of place among the demons came on stage to introduce himself. The young man blushed slightly and said shyly, "Hello everyone, my name is Vasak. I don't have much talent. I'll show you a manual skin change." As he spoke, he pulled away his skin, revealing the metallic bones inside. Ye Xuan: "..." I'm careless. Not only is this not a human being, it's not even a living thing. 3. Later, Ye Xuan discovered that he himself seemed not to be a human being. Intention: Study actively, make progress every day, and be a pillar of the country.
