The wild grass on the ground turns green and then yellow, yellow and then green, layer after layer.
The city's scale expands and then shrinks, shrinks and then expands, repeatedly.
Three times has the teaching building within Rhein University been rebuilt, the White Jade Statue at the entrance has been refurbished five times.
Everything is changing.
Everything is replacing.
The only thing that remains unchanged...
Seems to be the hafnium alloy trash can robot beneath the White Jade Statue, unchanged for decades, centuries, day-to-day.
It still gleams silver.
It still works diligently.
It still works lethargically.
Every day, many students pass by the statue, and they can see this hafnium alloy trash can that never fades, never scratches, picking up garbage here.
It's always so new, yet always so old.
