Help! My Colleague Is an Ancient Demon Lord

Shi Yan, the ancient demon king, came back from seclusion for three thousand years and prepared to rebuild the glory of the demonic way. As a result, he fell from the sky and crushed the crown of the new demon king. The next second, the director of the human resources department took out the QR code and scanned it. "Comrade, please don't create panic in public places. Please register first." The token was withheld - "There is no anti-counterfeiting mark attached." The floor tiles were cracked - "Eight hundred for one piece, deducted from salary." If you want to rule the Three Realms - "The Three Realms are under the control of the Bureau of Culture and Tourism. You must first approve it." Just like that, the most powerful demon in history signed a labor contract and sat in the cubicle. Sitting next to the work station was a girl eating potato chips and watching a movie - she was his archrival three thousand years ago and had been working for five years now. The director of the human resources department upstairs is writing an "Analysis Report on the Emotional Fluctuations of the Observed Subjects" every day. The master chef of the cafeteria studied the recipe for a month for his sentence "Why is meat sweet?" Later, someone asked Shi Yan: Do you still want to destroy the world? Shi Yan thought for a while: "... Let's talk about it next month. This month's KPI has not yet reached the target."
