At the age of 24, having graduated from university and secured a stable job, Yang Pann found himself yearning for more. His life, while comfortable, had become monotonous, and he often felt the urge to break free.

His life took a turn when he stumbled upon a magical little shop. From that moment on, his fate was destined to be anything but ordinary. The shop, more akin to a small museum, housed a variety of items, each a product of a movie, game, or novel.

"Is this a dinosaur's claw? It looks quite real."

"This must be the head of an alien. It looks quite scary."

"I think I've seen this knife in that game before."

Suddenly, a series of mechanical notifications echoed in his ears. "Identity confirmed. Beginning binding. Identity serial generated: 97762. Probationary executor number 97762, please pay attention. The trial will begin in one minute. Please prepare yourself."

Yang Pann found himself selected by the Infinite Space, a power of undeniable magnitude. It periodically dispatched its subordinates to different worlds to complete assigned missions. Successful executors would receive rewards, even a superman bloodline. However, failure to complete the missions would result in punishment. The process was simple, yet cruel.

As Yang Pann woke up, a translucent screen appeared before him, displaying notifications and a countdown timer. He was now part of a grander scheme, a pawn in the game of the Infinite Space.

What adventures and challenges await Yang Pann in his new role as an executor of the Infinite Space?
