Wang Chen stood at the door of Jiangcheng University, holding the crumpled recruitment notice in his hand, and couldn't help but twitching at the corner of his mouth. The notice clearly stated "We are looking for professional lecturers related to ancient book restoration and traditional magic techniques", but as soon as he entered the principal's office, the principal Zhang with Mediterranean hair slapped the table and spat: "Xiao Wang, our mathematics department is short of people. I see on your resume it says 'proficient in numerology'. Isn't this a close relative of mathematics? That's it, you will start teaching advanced mathematics to freshmen next Monday!"
