Su Yu had a plan in mind, then started wandering aimlessly around the city.
He still maintained his invisibility, observing everywhere.
After wandering for several hours, the sky gradually darkened.
"The residents here..."
The more Su Yu looked, the more he frowned. He found something odd about the residents in this city.
Because the relationship between these residents and the various mechanical creations was very strange.
In this city, various mechanical creations were running around everywhere, many of which were vehicles.
Initially, Su Yu thought that these mechanical creations were the city's public facilities, like buses and such.
But upon closer inspection, he discovered that those mechanical vehicles were empty; no humans were riding in them.
These mechanical creations were not serving humans.
On the contrary, it was humans who were serving these mechanical creations, cleaning, charging, repairing them... doing various chores.
