On my first day of employment, I watched helplessly as my colleague at the next station worked overtime and was eaten by the floor. In this weird company, the more involved you are, the faster you will die, and the only way to survive is by fishing. Everyone tried their best to climb up, but I was the only one who made it to the end by exploiting loopholes in the rules. When I touched the seventh floor, I discovered that everyone who climbed to the top would become the nourishment of the tower.
