This Underground City was even more impressive than the one above.
The streets were actually paved in concrete.
The streets of the base above were all dirt, worn down by foot traffic.
Here, the population was sparse. They had been squatting there for a while and didn't know whether it was too remote or there were simply few people around, as they hadn't encountered a single person all that while.
They had originally planned to squat and question someone, but since no one showed up, they just had to move around and see.
As it turned out, it was indeed because the street they were on was too remote, which was why there were no people.
As they walked on, they encountered more people.
These people were also very neatly dressed, and they walked in the middle without any mismatch.
However, they were all men.
At this point, Su Yinhe was glad she had disguised herself.
If she, a woman, walked among them, it would definitely be conspicuous.
