In front of them, a massive Sky Island appeared.
The size of this Sky Island was as large as a planet.
However, the size of the Sky Island wasn't the most surprising thing.
What surprised them the most was the presence of many modern buildings on this Sky Island.
Tall buildings, city streets.
Even various artificial lakes and man-made forests appeared one by one on it.
They also saw some black vehicles speeding crazily on the streets.
Cheng Jianyong exclaimed, "Whoa, what kind of civilization is this?"
"I seem to see various cars and some small flying devices!"
Yes, besides those vehicles running on the ground, they also saw some flying devices running in the sky.
Han Xing pondered, "The mortals in this world have a power level similar to our Blue Star. However, their technology seems to be slightly more advanced than ours."
"But it seems their civilization hasn't been around for many years."
"Somewhat strange."
