Can you write a short funny story about a middle aged man working a office job and his daily live, which uses many different tropes from Chinese xanxia and wuxia stories?
Once upon a time, in a bustling metropolis, there lived a middle-aged man named John, who worked a mundane office job from 9 to 5. But little did his coworkers know, John had a secret obsession with Chinese xianxia and wuxia stories.

Every day, during his lunch break, John would retreat to the rooftop of his office building, where he practiced his sword fighting skills with a broomstick, channeling his inner warrior. He imagined himself as a powerful cultivator, fighting off evil demons and saving the world from destruction.

But one day, John's fantasy became reality. As he was battling imaginary foes, a gust of wind blew a mysterious talisman onto the rooftop. Without thinking, John picked it up and felt a surge of energy coursing through his veins.

Suddenly, he was no longer a mere office worker. He had become a powerful cultivator, capable of flying through the air and summoning powerful spells. His mundane office job was now a distant memory, as he embarked on a quest to rid the world of evil spirits and villains.

But as he was battling a fierce demon in the city's central square, he suddenly felt a sharp pain in his back. It turned out that the talisman had been a fake, and he had merely been stabbed with a pencil by one of his coworkers, who had been watching his antics from afar.

As John slumped to the ground in pain, he realized that he may not be a real cultivator after all. But he also realized that his daily office life wasn't so bad after all. He laughed it off, picked himself up, and returned to his desk, ready to tackle the next report with renewed vigor. From that day forward, he knew that his xianxia and wuxia fantasies were better left in the realm of imagination.
