Zheng Tan followed the two people from not too far away, moved his ears, turned his head to look back, and noticed that Black Gold was following behind but did not immediately catch up; instead, he kept some distance.
Cats have the advantage in terms of size and agility, so maintaining some distance was better to avoid being detected by the two people ahead. As long as he followed Zheng Tan, Black Gold wouldn't lose track of him.
The two individuals also glanced around while talking but didn't notice anything unusual, which made them feel much more at ease.
However, these two didn't realize that sometimes, the followers weren't just people but could also be animals. Maybe they thought that, in the cold winter daylight, there wouldn't be any dangerous animals around?
