Chapitre 1397: The speed of killing

The clinic was located in the High-tech Zone of Hailan city, which wasn't a bustling area. When Zhao Yu walked onto the bridge, there wasn't a single person on it.

The traffic under the bridge was not as dense as he had imagined. The cars were moving back and forth, as if they had slowed down the pace of the entire city.

After following Zhao Yu onto the bridge, the police officers were naturally anxious and at a loss. They didn't understand why Zhao Yu wanted to come here.

Then, something happened that made them even more confused. Zhao Yu was looking at something on the bridge. He suddenly squatted down and sniffed the railing like a Hound.
