In Greek mythology, there was a god who was punished by the gods - Sisyphus. He was cursed to roll a huge boulder up a mountain every day. However, because the boulder was too heavy, it would often fall off the cliff on the way. The first half of his efforts often failed halfway, so he had to repeat this thing endlessly, and his life was lost in this meaningless repetitive work. The gods saw no greater punishment than this. But what did Sisyphus think? Does he derive happiness from ineffective work day after day? Got some inspiration on a boulder? Xerxe thought that it was boring enough that she was stuck in the office every day doing ineffective work like a Sisyphean boulder. When she time and time again traveled to the afternoon when she was assassinated in the Northern and Southern Dynasties, and died again and again, maybe office work was not so boring after all.
Purpose: People must imagine Sisyphus's happiness, because the struggle toward heights itself is enough to fill a person's heart.
