Dou Dou headed east along Chunhua Second Road.
Upon reaching the intersection with Chunhua Third Road, she turned north onto it.
She kept her head down, moving at a slow, stop-and-go pace. Shen Xin followed on foot, while Sun Zhao and Chen Chao trailed behind in their car.
She ambled along until she reached the end of the road.
Ahead of them was East Yang Road.
It was a major, six-lane, two-way road bustling with traffic. Dou Dou stopped here.
She sniffed all around, first heading east for a bit before stopping and doubling back. Then she went west, but after a short distance, she stopped again and returned to the intersection once more.
The others had already gotten out of the car and were waiting by Shen Xin's side.
"Shen Xin, I think Dou Dou has lost the scent source," Li Jiahui said. "There are too many interfering scents here. And look at the road—a street sweeper must have come through this morning."
Shen Xin called out to her.
Dou Dou immediately ran over.
